How to make a corn crusher with your own hands?

How to separate corn kernels from the cob at home

Usually in cooking, the purified product is boiled and then consumed, without first separating the grains. But there are times when you still need to separate them. We will describe how to do this below.

Manually

It is most convenient to peel boiled corn with your hands.

Here's one way:

Boil the culture and cool it so that you can hold the cob in your hand.
Place a wide container in front of you.
Take a sharp knife in your working hand, and hold the corn in the other.
Using the tip of the knife, carefully begin to pick out one row of grains.
Use this method to go to the end of the row and repeat for the rest. You can separate the remaining rows of grains with your hands.

Using a peeler

It is better to clean raw corn using a sheller. This device is a container, inside of which there is a metal disk with teeth (peeler), driven by a motor or manually. The blades located just below the disk direct the grains into the outlet chute.

All actions when working with this device are very simple:

Prepare the cobs. Free them from foliage.
Place the container with the product near the peeler.
Place a container under the outlet of the device to collect the finished product.
Load the cobs into the sheller and turn on the device.
Open the bean collection flap.

Nuances of processing corn plantings

Due to the fact that there are now a lot of drugs against weeds, it is worth choosing them wisely. So, for any herbicide product there are instructions from the manufacturer, which must be strictly followed.

If herbicide treatment occurs before emergence, care must be taken to ensure that the solution does not penetrate below the seeds. Most reagents that are applied directly to the soil only work if the soil has sufficient moisture.

To prevent a negative impact on the quality of the crops grown, the last treatment of the site is carried out 1 week before the start of harvest.

Types of weeds growing in crop rows

Weeds are divided into annuals and perennials. Annuals that most often infect corn include barnyard grass, wild oats, crabgrass, and others. Perennial weeds include the following: knotweed, cornflower, chistets, pigweed, peas and others.

Deadlines

It is important not only to correctly select the necessary drug, but also to determine the optimal period for processing the crop.

Pre-emergence

To effectively control weeds, it is recommended to carry out pre-emergence treatment using products that are aimed at destroying a complex of weeds. However, these drugs only work when we are talking about annual or biennial plants.

Post-emergence

Weeds pose the greatest danger to corn in the 3-10 leaf stage. However, at the moment when there are already 6-7 leaves, most types of crops are susceptible to the negative effects of reagents. For this reason, a section of seedlings up to 3-4 leaves is considered a suitable time for treatment with pesticides.

Principle of operation

A motor powered by electricity is present in all types of units. Let's look at how to peel corn at home with a large sheller. It is equipped with a disk; its teeth are not sharp, have a roundish shape. The height of such teeth varies from 6 to 8 mm. The disk itself resembles a sieve in appearance due to the large number of round holes for grain.

The body of the device must be closed with a flap, so the crop will not scatter to the sides. There are designs with a cob tray attached to the body. The lid for cleaning the device is located at the bottom. This model helps to significantly save time: the first batch is processed in the housing, and the second waits its time in the tray.

After placing the crop, the motor rotates the disk (more than 45 rpm). The corn is pressed down by its mass, beats and clings to the teeth. The grain begins to pour into the holes of the disk and the gap between the cylinder and the disk, from where it flies out into the lower section of the device. There is no acceleration, so the finished product is poured through the chute into a prepared container or onto the ground. Light cobs are pushed up by heavy ones. If the beans stop pouring out, it's time to throw away the waste and load a new batch.

The operating principle of small-type devices is the same, however, there are differences in the design of the device. A pipe with teeth is attached to the rotating disk. Due to the fact that the teeth are directed inward, the grains cling to them well and then fall into the container. The empty cob does not fall anywhere, it remains in the hands of the owner. The cleaning element of the large device is located horizontally, and the small one is located vertically.

Drawings of various designs of garden shredders

Let's look at several designs of shredders that you can assemble yourself.

Drawing of a hammer grinder

A hammer chopper can crush branches, straw, corn stalks, and grain.

1 — loading hopper (sheet δ1 mm); 2 — edging of the neck of the loading hopper (corner 25x25); 3 — damper/valve (sheet δ1 mm); 4 — M6 bolt for tie (8 pcs.); 5 — framing of the loading hole in the housing (equal-flange angle 25 mm); 6 — M8 pin (8 pcs.); 7 — outer drum of the housing (pipe Ø 270x6); 8 — stator with grooves (pipe Ø 258x6); 9 and 20 — hammers and spacers (sheet δ3 mm, hardened to hardness HRC 45–47, 72 pcs. and 70 pcs., respectively); 10 — latch Ø 3 (4 pcs.); 11 — M20 nut with a spring washer; 12 — hammer axis (circle Ø 22, 4 pcs.); 13, 14 — piping of pipes (equal-flange angle 25 mm); 15, 19 — gaskets (rubber, sheet δ3 mm); 16 — M8 nut for fastening the flange (8 pcs); 17 — hammer rotor; 18 — flange (sheet δ5 mm, 2 pcs.); 21 — clamp; 22 - drive shaft

Cutting tool - circular saw package

A package of 15–30 circular saws mounted on a shaft is one of the options for the cutting system of a shredder. Some craftsmen point out that saw teeth quickly become clogged with plant matter. Others claim that they achieved good performance of the tool empirically - by setting the teeth differently relative to neighboring saws. Since carbide teeth are thicker than the disk itself, thin separators made of metal (for example, washers) or plastic must be installed between the saws, and the entire package is clamped with nuts.

Pack of 15 saw blades on shaft

As a drive, you can use a low-power walk-behind tractor, pulleys and bearings - used parts from a VAZ car. The bell of the loading hopper is a truncated pyramid, the outlet hole is small so that a person’s hand does not pass through. It is better to make the frame for the chopper higher in order to remove the crushed raw materials less often.

Double roller shredder

This chopper chops branches into measured pieces from 2 to 8 cm long, convenient for heating a bathhouse or wood-burning heating boiler. Its design consists of two shafts with knives - 3-4 pieces per shaft, rigidly secured with bolts. Knives can be turned from KamAZ or MAZ springs. If you can find a bulldozer knife, that will also work. The shafts are fixed on massive sheets in parallel, at a distance sufficient for the knives to cut the branch without clinging to each other. Free rotation of the shafts is ensured by bearings, and their synchronization is achieved through a gear clutch moving by a belt (chain) from the engine. To drive this chopper, it is advisable to use a high-power engine, but at low speed.

If you want to create a mobile shredder, you need to provide mounts for wheels on the frame.

How to choose the right grain crusher for your household

In fact, when choosing a grain grinder, you need to focus on only one value - the grind size. This is the main characteristic that affects its performance.

As for the grinding method, it is more secondary than key for choosing a grain crusher, but it still depends on what kind of grain you are focusing on, which one will be the main one.

Hard grains, for example, are best crushed by impact and pressure, plastic grains are best processed by abrasion, and brittle grains are easiest to crack.

In this regard, crushers are produced with different grinding mechanisms: jaw crushers, which are based on two plates - movable and fixed. This mechanism grinds the grain like a mill, and they are well suited for plastic grains.

A cone crusher works on a similar principle, the only difference being that cones are used instead of plates. A roller crusher crushes grain using two shafts; when it falls between them, it is flattened. Excellent for fragile grains. The impact crusher is the most common option.

This is exactly what a coffee grinder looks like; you can grind anything with it. But best of all, the design of its mechanism is suitable for dealing with hard grain . And if necessary, such a crusher can grind any grain along with hay into a homogeneous mass.

Therefore, before choosing a grain crusher for the household, you need to immediately decide for what purposes and for what grains it will be used.

Also, you need to take into account the volume of grain that will need to be ground during the day - it is clear that a crusher with high power will cope with a large volume much faster than a low-power one.

Another feature that is worth paying attention to is the materials from which the device is made.

Since a grain crusher is an agricultural implement and is intended for use in a wide variety of conditions, the body of this product must be manufactured accordingly.

Thick steel that is very difficult to bend, deform or damage is the best option.

If the walls of the grain crusher are thinner than 2 millimeters, the first deformations will appear immediately. And they will continue to appear until the moment when you have to equalize them yourself. Therefore, the thickness of the metal must be sufficient to withstand heavy weight.

Also, the quality of painting of the product is important . It must evenly cover all surfaces of the product in order to protect the metal from corrosion.

The quality of the paint is also of great importance - powder paints are perfect for this purpose, they are resistant to impact and abrasion. As for enamels, chips from small impacts will not keep you waiting. This is about appearance.

Regarding the maintenance and warranty of the grain crusher, it is best to purchase a product manufactured in the CIS countries.

They should be given preference in the first place, since you can always find parts for them that cannot be made on your own, moreover, usually such production facilities have been operating for many years and the equipment they produce is reliable and tested by many customers.

Rostselmash

Russian is a leading leader in the production of agricultural machinery.

Self-propelled and trailed complexes for harvesting and preparing high-quality silage are unpretentious, economical and efficient, and therefore are in demand not only in the CIS countries, but also abroad. Thus, the modernized self-propelled 4-row combine harvester KPS-4-1 for harvesting corn on the cob was developed specifically for work in China.

For medium and small livestock farms up to 500 heads and large agricultural firms, the manufacturer has created the DON 680M universal forage harvester with a machine throughput of 100 t/h.

Technical features of the module:

installation of the cutting drum cuts in the form of the letter V;
availability of an unloading accelerator;
removable rotary type grinder at 3848 rpm;
ergonomic Comfort Cab;
adjustable steering column;
advanced system for adding preservatives.

The combine is equipped with a YaMZ-238 V8 engine with a power of 290 hp in a transverse position. With. with turbocharging and built-in heat exchanger.

The fuel tank capacity of 540 liters is enough for 11 hours of operation.

Fuel consumption - 430 g per 1 ton of silage.

How to make your own corn husker at home

Corn cobs don't last long. When harvest is over, it is important to process them quickly. Hand processing a large volume of corn is a monotonous, tiring task. To save time and effort, you can make your own corn sheller.

general description

You can make your own corn husker using a drawing. Peelers are divided into 2 types:

Big. Used on large farms. The huller is designed for different sizes of corn. It is filled in buckets (from 8 kg) or bags. Cleaning time is 3-5 minutes. In 1 hour of operation, the device processes 500 kg of crop.
Small. Designed for use at home for peeling one cob. It is inserted into the hole of the device and held with your hand throughout the peeling process. The motor of a small peeler burns out when there is a large volume of work.

The electromechanical unit has 2 holes: the first hole is where corn is filled or inserted, the second hole is where cleaned grain comes out. Bare cobs are unloaded from a large drum. They are taken out by hand. Some types of devices simplify the work: they push empty cobs away from the grain.

A corn husker is a simple tool to make; however, you need to select the dimensions of the parts that correspond to the amount of harvest.

Principle of operation

How to make?

To make a corn husker with your own hands, it is important:

Use of durable materials and parts.
Selecting the appropriate volume of the device.
Availability of detailed, step-by-step instructions.

To create an electric corn husk, prepare:

The basis for the unit is made of durable material (aluminum, dense plastic).
Reservoir for cobs. It could be an old, unnecessary thing (a hopper from a washing machine, a cylindrical container).
Damper on the body.
Disc with teeth.
Toggle switch (switch).
Scraper.
Flange.
Motor.

The creation of the structure begins with fastening the base and tank with rivets. The grain removal mechanism is connected to the tray shield. A toggle switch with a magnetic starter is installed on the wall of the tank. Holes (no more than 14 mm) are drilled into the disk with a drill, teeth are welded, semicircular for farming or sharp for small harvest volumes.

The tray has 2 holes: one for grain and the other for empty cobs. 2 plates of 2 cm each are attached to the bottom of the chamber. They are needed to support the rubber scraper. Its task is to direct corn cobs from one side to the other. The flange is attached to the motor shaft.

Homemade corn husker

The drawing diagram of a corn huller provides a base - this is a cylindrical aluminum pipe from a water irrigation system, connected with rivets. It is bolted to the base of the device. The grain separator is connected to the tray shield with rivets. The toggle switch is attached to the side wall of the cylinder. The disc is equipped with semicircular teeth. To increase the rigidity of the disk, a 6*35 mm tire is welded.

2.5 cm plates are welded perpendicular to the disk. A rubberized scraper strip is bolted to the plates. The bottom of the bunker is equipped with a tire; the cylinder is screwed to it using bolts. There is a flange on the electric motor shaft, and a disk is attached to it. At the end of the flange there are 3 leading fonts. The gear disk rotates counterclockwise. This promotes self-tightening of the bolt and facilitates the exit of empty cobs through the door, which closes during shelling.

Self-production

The cost of grain grinders and grain crushers sold on the market is quite high, so it makes sense to make the unit yourself. Before you begin, you should carefully study the instructions, and also watch videos of how to make a grain grinder; there are many of them on the Internet. The simplest and most economically feasible option is to make a grain grinder from old household appliances.

Tools and materials:

Motor from an old vacuum cleaner or washing machine.
A square of plywood with a side of 30 cm.
Durable metal plate with dimensions 1.5x20x1.5 cm.
Steel strip 70x6 cm.
Three rods (possibly wooden).
Net. The size of the cells depends on the size of the finished product. Several meshes can be used depending on the grain being processed.
Container for collecting the finished product.

Operating procedure:

Attach the motor from a vacuum cleaner or washing machine to a square of plywood so that the shaft protrudes 4 cm downwards.
Sharpen the metal plate like a blade, in the direction of the axis of rotation. Make a hole in the middle corresponding to the diameter of the motor shaft and firmly attach it.
Make a working chamber by bending a steel strip into a ring. Insert three rods into the bottom of the chamber for secure fixation.
Install a mesh with holes of the required sizes.
Place a container or bucket under the mesh to collect the finished product.

There is also a simpler option. When working with small volumes, the design can be simplified so much that you can do without a motor . And its production will take very little time.

You will need two logs from which the millstones will be made. It is better to use blanks made from hardwood of deciduous species (not coniferous, to avoid the ingress of resin). Oak or beech are ideal options:

From logs with a diameter of at least 2.5 cm you need to saw off pieces 25 cm long.
The contact surfaces of future millstones must be serrated. To do this, you can drive nails or any parts made of cast iron or steel into them.
A through hole in the form of a funnel should be made in the upper millstone for loading grain. You also need to install a handle.
Cover the upper part of the lower millstone with a tin strip 150-200 mm wide.
Attach a magnet near the hole for crushed grain to catch small particles resulting from abrasion of the metal teeth.
At the bottom, install a chute for collecting processed grain and a container for collecting it.

The principle of operation of such a grinder is very simple. With one hand you need to rotate the millstone by the handle, and with the other you need to gradually add grain. Finally, the resulting product is passed through a sieve for final screening.

Another simple option: a grain grater . Required:

Make two cylinders from tinplate so that the diameter of one is 2-3 mm smaller than the other. You can use clean canning jars of the appropriate size.
Using a nail and a hammer, make indentations on the sides of both cylinders to turn them into a kind of grater. On the outer cylinder, the sharp edges of the holes should be directed inward, and on the inner cylinder, outward.
Place the smaller cylinder on a wooden stake with a diameter of 200–250 mm, and close with a conical lid. Nail a rectangular wooden block 40 mm thick from below.
Make a base plate from wood with a hole that is the same size as the block and connect them so as to ensure the immobility of the inner cylinder.
Place the handles on the outer cylinder and insert the cylinders one into the other. After this, you can add grain and grind it by rotating the cylinder by the handles both clockwise and in the opposite direction.

Corn huller: description, principle of operation, how to do it yourself

The autumn harvest always ends with its careful preparation for the long winter. This issue is especially acute for farmers who focus on growing corn, since the cob is not stored for long.

That is why most people resort to a variety of methods for cleaning the grain from the base, one of which is an automatic corn huller.

From this article you will learn how to inexpensively make a corn husk with your own hands from scrap materials.

Step-by-step manufacturing instructions

To build a simple unit for cleaning corn grains, you need:

Create a strong support for the structure (this can be a strong table, an old base from any device). The steel stand can be welded from metal corners or a profile pipe (height 80–100 mm).
Attach the electric motor to the support using a bolted connection; to do this, drill the corresponding through cavities in the support according to the mounting holes. You can replace a bolted connection with a solid weld.
Attach the engine starting mechanism (power button) to the support with bolts, and then connect it to the engine. A cord with a plug must be attached to the reverse side.
Install the working part on the motor shaft. It is a steel pipe with a diameter of 5 cm, a length of 20 cm and a thickness of 2 mm. On one edge, parallel teeth are cut, slightly curved inward, and on the opposite edge, an adapter with bolted fasteners is attached for attachment to the shaft.
Attach a protective metal casing to the structure; its lower part should contain a chute for discharging grain, and its side should contain a hole for feeding grain. The most suitable alternative to the casing is the exhaust duct of the old ventilation system.

The device can be assembled in a few hours; later, after changing the teeth for sharp cutting, it can be used to construct a chopper for corn stalks and other plants, for preparing fresh feed, as well as silage.

Important! The working part must have wide longitudinal holes, otherwise the grain will gradually accumulate in it during operation, which makes cleaning much more difficult.

You can create a crusher with a more aesthetic appearance; for this you will need to get an old washing machine.

Top-loading models, like the Aurika washing machine, are best suited for conversion.

: Washing machine corn sheller

The main stages of manufacturing this peeler are as follows:

Create a strong support; for this you can use a small steel table or weld a tripod from metal rods.
Place a shallow container with sides at least 5 cm high at the top of the support; it will serve as a collection container.
Make a hole in the bottom of the collection container, 1 cm wider than the thickness of the shaft.
Attach the motor to the bottom of the support so that the shaft is pushed up through the bottom of the collection container.
Cut the bottom of the washing machine drum and attach small legs to it with bolts or a weld.
Secure the drum over the shaft, exactly in the center, with the legs resting on the bottom of the collection container.
Install a cleaning disk on the shaft; its diameter should be 1–2 cm narrower than the size of the drum. It can serve as a lid from a saucepan with numerous holes up to 10 mm in diameter and welded small teeth up to 8 mm high.
Mount a cover from the remains of the drum bottom; secure it using curtains with a bolted or welded connection.
Screw the trigger mechanism (switch) to the support and connect it to the engine, the reverse part should be attached to the cable with the plug.

Important! For the design of the device, you should choose a motor that provides a rotational torque of the hulling disk of no more than 50 rpm, otherwise the grains will be damaged, which makes them unsuitable for long-term saving.

A corn huller is one of the most important and sought-after devices for the modern farmer.

There are many units of this type on the market, both industrial and home-type, but you can also make it yourself, using improvised materials.

To do this, you will need a small set of tools, as well as spare parts from old equipment, including an old washing machine.

Corn harvesters - characteristics, classification

Corn, as one of the main tall crops, is quite labor-intensive in terms of cultivation and harvesting. In agriculture, the value is not only of the cobs with seeds, but also of the leafy mass itself, used as livestock feed.

In order to invest in harvesting time, produce high-quality threshing and spend a minimum of energy resources, corn harvesters come to the rescue. Despite the fact that their variety is less than that of grain harvesters, the demand for them does not decrease.

Classification of corn harvesters

Corn harvesters can be classified according to several criteria:

design;
the nature of the reaping part;
functional purpose.

Based on the first characteristic, combine harvesters are distinguished:

self-propelled – full-fledged corn harvesting machines with their own power plant and drive wheels or tracks;
trailed – connected to the tractor via a PTO;
semi-mounted – installed on grain harvesting equipment in the form of adapters.

By header type:

Depending on the purpose of harvesting - for grain or vegetative parts:

silage;
for harvesting grain.

Characteristics of trailed corn harvesters

Trailed corn harvesting units are most often two-row devices powered by a tractor diesel engine. As a striking example, consider the Khersonets-7 trailed corn harvester. It is designed for cutting crops with a row spacing of no more than 90 cm.

The scheme of its operation is considered classic and looks like this. The stems along with the cobs are captured in the lumen of the header and enter the cob separator.

By pulling through the tear-off plates, the shoots are freed from the seed cobs, which go into the cob auger. From this part, the unthreshed parts of the corn move through intermediate conveyors into the husker.

An equally well-known domestic model of trailed combine harvesters for corn harvesting is the KKP-3, which today has been replaced by the new generation of corn harvesters “TORNADO” 80. These 2-row mechanisms, thanks to modern equipment, husk corn at high speeds.

Self-propelled corn harvesters

They are units that perform the following functions:

cutting off cobs, pre-cleaning them and crushing vegetative organs;
milking of cobs and harvesting of leafy stem residues;
silage of corn at the stage of milky-waxy ripeness.

Among the most famous self-propelled corn harvesting units is the Khersonets-200 KSKU-6A combine harvester. The technological diagram of its functioning is conventionally shown in the figure,

where the numbers correspond to:

1 – plants;
2 – capes;
3 – cob separators;
4 – grinding element;
5 – conveyor;
6 – storage for cobs without wrappers;
7 – crusher;
8 – inclined chamber;
9 – knife block;
10 – side tape;
11 – cob peeler;
12 – auger for plants that have not been cleaned.

An alternative to large-sized combines today are self-propelled mini-harvesters for harvesting corn. Most of these modifications are offered by Chinese manufacturers. For example, the 4YZ-3F, the photo of which is located below, with a weight of 5.4 tons, develops a power of 155 hp.

Attached corn harvesting equipment

Standard headers, which are equipped with modern grain harvesting units, are used as auxiliary adapters for this operation. The simplicity of their design allows you to replace the header and re-equip the thresher yourself.

For example, the Niva SK-4 combine is equipped with a ZhKN-2.6M header, and SK-5, SK-6 are equipped with PKK-4. They differ from each other not only in their grip width, but also in their operating principle.

ZhKN-2.6M has a reinforced feeder chamber and a beater drum, and PKK-4 is characterized by picker-scraper cob separators and a rotary grinding apparatus.

As mounted corn harvesters, you can use homemade mechanisms that are created on the basis of a mini tractor or walk-behind tractor.

The principle of operation of a crusher from a meat grinder

I would like to note that the operating principle of almost all grain crushers is identical and somewhat similar to the operation of the simplest coffee grinder in the kitchen, except that the scale of grain processing is much larger.

The self-made unit will be connected to a regular 220 V electrical network, which will be supplied to the electric motor.
The grain necessary for grinding is poured into a special reservoir located on top of the meat grinder for further processing.
Then the raw material enters the crushing chamber, where the grain processing process is carried out using a special knife.
The grain, crushed until ready, goes through the appropriate holes in the meat grinder into a container - it can be a bucket, pan, deep cup or something similar.

The main component of the crusher is an electric motor, which can be used with medium power and medium rotation speed. Crushed grain through a crusher from a meat grinder can be used, for example, in mash for rabbits , feed for pigs, chickens, ducklings, or for fishing baits. In this crusher you can grind almost anything, even seeds and dry bread.

How the device works

The operating principle of a homemade corn husker is simple. Corn cobs are poured into the unit body from above. Then the motor turns on, which, using a belt, begins to rotate the shaft and, accordingly, the peeling disk.

Teeth or other growths on the disc knock the kernels out of the cobs. They fall into holes and gaps, fall to the bottom of the body and, with the help of one or more rotating blades, centrifugal force and air flow, fall into a chute, through which they then exit into a container placed in advance or into a tied bag.

With the help of gravity and centrifugal force, full ears fall down and are crushed by teeth, and empty ones rise up. When the damper is opened to release the cleaned cobs, they fly out to the ground.

Do-it-yourself grass cutter driven by an angle grinder

I have birch trees growing in my dacha. Leaves are falling from the trees. We have to clean it up, burn it, and fill up the compost pit. The foliage takes a long time to rot. I decided to chop it up. For this you need a grass cutter. I looked at what they were making on the Internet. I turned on my brain and this is what I came up with.

Do you like an inexpensive option for a garden shredder? Read the article further and find out how to make a homemade product from an angle grinder and a metal tank. acted like this:

He thought about how to twist the chopper blades. The choice is small - install a motor from a washing machine, or buy an electric motor. According to the user, the motor from the washing machine is weak, and I didn’t want to purchase a three-phase unit and convert it to one phase.
Tok2Z
bought on the market, for 2 thousand rubles, an old grinder with a power of 2 kW and blades from a lawn mower for 700 rubles. I ordered an adapter sleeve from a turner, spending another 500 rubles.
I welded the frame and placed a galvanized water tank on it. I assembled the structure and turned on the grass cutter.

The turnover is crazy. I threw a shovelful of leaves into the tank, and they blew away! I checked where the flow was going. Air goes up from the edge of the tank and is sucked in in the middle. I cut out a galvanized ring and installed it in the center of the tank. Threw the leaves. The knives crushed it just right, and it flew into the lower pipe.

Homemade grass grinder from a grinder

A grass grinder made from a grinder is a fairly simple and quickly implemented option. To implement the project, you will need to stock up on the following parts and materials:

steel corners;
metal container (regular boiling);
homemade or ready-made knives (for example, from a lawn mower);
fasteners;
sheet metal.

Tools you will need:

electric drill;
welding machine and electrodes for it;
an angle grinder to cut corners;
spanners.

To assemble a shredder with your own hands based on an angle grinder, capable of grinding not only grass, but also branches up to 4 cm thick, it is recommended to use a power tool with a power of over 3 kW.

The creation of a grinding unit is carried out in the following sequence:

cut the corners into pieces with a grinder;
a frame resembling a chair is welded from them;
weld a shelf from a piece of sheet metal;
attach the grinder to the made frame (on the stand) with clamps, placing its shaft towards the top;
cut a hole about 10 by 10 cm in the side of the boil-out;
a sleeve, for example, made of tin, is attached to the slot, through which the ground plant mass will be dispensed from the container;
make a hole in the center at the bottom of the boil;
install the container on the angle grinder shaft and attach it with bolts or self-tapping screws to the metal frame;
Place the knife or disc on the angle grinder.

The result will be the design shown in the photo below.

The dimensions of the corners are selected individually to make it convenient to handle the mechanism.

Place a bucket or other container under the pipe for dispensing chopped grass with branches while working with the unit so that the processed plants do not fly away.

The created device can be improved. To do this, you will need a grinder shaft attachment about 15 cm long with two knives: at the upper end and in the middle. The blades are separated by a mesh attached to the casing wall.

How to make?

To make a corn husker with your own hands, it is important:

How to make a grain crusher with your own hands, video

A small grain crusher of your own is a very useful device for any farmer. With the help of a grinder, you can make food for rabbits or poultry at any time, grind feed from grain for livestock, or chop vegetables and fruits. In addition, the grain crusher can be used to make flour from grain for yourself, which is important for residents of rural areas. Knowing how to make a grain crusher with your own hands using drawings and videos , you can make farming easier.

Universal grass cutter and corn sheller

I also made a grass cutter. I mainly use it to chop grass for poultry. The basis of the homemade product is a kilowatt motor made in the USSR. I bought it for 1400 rubles. Works great. The engine is three-phase, but converted to operate from a 220 Volt network.

Making a homemade grass cutter step by step:

Holes were drilled and threaded in the flange.

The knives were made from a piece of an old rusty two-handed saw.

The knives were screwed to the flange.

The grass cutter frame was made from a sheet of metal 4 mm thick. A strip of metal with a cross-section of 4x40 mm was welded to the square, which was bent in a circle. A hole was drilled in the center of the bed.

I bent the strip with a hammer, striking the metal on the jaws of a vice. The radius was controlled in a circle by drawing it on the bed.

At the finish, the user welded the legs to the base. Fixed the electric motor. I made a large tank with a lid so that debris would not fly out of the grass cutter while the engine was running.

The tank is removable for ease of use of the grass chopper.

Varieties of engines for assembling homemade products

Electric and gasoline engines removed from unused equipment are used as a drive for homemade products. Each of these two options has its own advantages and disadvantages. Models with an internal combustion engine are more convenient in that their operation does not require a nearby power supply. But in general, they are more expensive and have a more complex design than their counterparts equipped with an electric motor. Therefore, it is easier to make electrical equipment, and also more compact.

The maximum thickness of cut branches that a branch chipper can grind depends on the power of the electric motor installed on it and the characteristics of the knives.

Models with a motor up to 1.5 kW are capable of grinding sticks up to 20 mm in diameter. They are designed for low intensity work.
If an electric motor of 3 to 4 kW is installed, then such units can chop branches up to 40 mm thick.
More powerful electric motors (over 4 kW) are used to make a shredder for wood with a diameter of 7-15 cm.

To create a homemade shredder, you can use electric motors from an angle grinder, washing machine, or trimmer. They must be adapted to work from a stationary network with a voltage of 220 V. In order to grind material as thick as possible at home, it is recommended to equip the shredder with an electric motor of 1500 rpm with a power of about 3.5 kW. This parameter for internal combustion engines corresponds to 5-6 horsepower.

Good afternoon. I decided to modernize my household grain crusher. Extra hole and serve corn on the cob. . How to feed a cob 1. Parallel to the motor axis. In this case, the first knife hits, the second one should not bring the cob to 3 and 4. 2. Perpendicular to the motor axis. In this case, the ends of all knives are struck at the end of the cob. What interests me first of all is not the rapid destruction of the electric motor bearings. Who did it? Say the word.

I asked my husband to do it, he said that it is not economically profitable at home, it’s easier to take it to the factory and have it detailed.

Hello. See the topic How to separate corn from corn.

Wherever you are, always with you!

We'll definitely look into it, but the question seems to be how to grind it together with the cob.

Corn crusher in the easiest way)

The feed value of corn grain is determined by the high content of nitrogen-free extractive substances and starch in them. Corn fat is rich in unsaturated fatty acids (oleic, linoleic) and has a high iodine number - 125.

Corn is richer than other cereals in carotene (from 1.5 to 9 mg per 1 kg). It is recommended to feed corn grain to animals in a mixture with barley grain and meal. Good results are obtained when feeding corn to dairy cows in combination with protein-rich concentrates.

The maximum supply of corn grain to dairy cows when selling whole milk is 4 kg, when processing milk into butter 2 kg, when making cheese 3 kg per animal per day.

Corn is fed as ground grain. Finely ground corn is fed to cattle and pigs, and in the form of coarse corn to horses. Poultry are fed corn in crushed or ground form. The cost of 1 kg of live weight gain in bulls with the concentrate type of feeding is 2 times lower than with silage-concentrate feeding. More expensive concentrated feeds make it possible to obtain cheaper livestock products. With an increase in the proportion of concentrates in the animal diet, the productivity of fattening cows and cattle increases. And, despite the fact that these feeds are much more expensive than grass feeds, the cost of milk and meat is lower due to less feed consumption and higher digestibility.

Recommendations for feeding cracked corn:

Corn protein contains relatively few essential amino acids, so it is fed with feed that is complete in protein: peas, cake, animal feed, hay and legume grass.

Crushed corn is the best feed for chickens. Corn adds vibrant color to egg yolks. It is better to feed crushed corn to the bird at night, then it will remain full until the morning. Corn is good to feed to chickens and roosters. Chickens grow quickly, develop and gain weight, and the tough, dry rooster meat becomes more tender. Chickens should not be overfed with corn, as an overweight bird will stop laying eggs. The bird is heavily fed corn when preparing it for slaughter so that it quickly gains weight.

Crushed corn can be fed to young rabbits. They develop well and quickly and accumulate little fat. However, it is better to limit feeding corn to adult rabbits as there is a risk of developing obesity, which negatively affects reproductive function.

Always remember that to raise healthy livestock, feeding must be varied and balanced.

general description

You can make your own corn husker using a drawing. Peelers are divided into 2 types:

Big. Used on large farms. The huller is designed for different sizes of corn. It is filled in buckets (from 8 kg) or bags. Cleaning time is 3-5 minutes. In 1 hour of operation, the device processes 500 kg of crop.
Small. Designed for use at home for peeling one cob. It is inserted into the hole of the device and held with your hand throughout the peeling process. The motor of a small peeler burns out when there is a large volume of work.

A corn husker is a simple tool to make; however, you need to select the dimensions of the parts that correspond to the amount of harvest.

Advantages of a homemade option

Unlike factory models, a homemade shredder does not require excessive care. It will become a universal assistant in the household and will help not only to chop branches and other household waste, but also to crush fruits (apples, pears, plums), along with the seeds. This is very convenient when you need to make jam, puree or homemade wine when the fruits are crushed to a paste.

Garden shredder in action

It is also worth paying attention to the cost savings when using a homemade shredder. Firstly, manufacturing will initially be cheaper than buying a factory device, and secondly, a “homemade” device will not need to purchase expensive parts if it breaks down - all its elements are not expensive.

A homemade garden shredder can crush even large branches, turning them into chips

In addition, a homemade garden shredder is highly productive. All waste loaded into the hopper will be pulled into the saw blades and disappear at incredible speed. Thus, a homemade device can be no worse than an expensive and modern garden tool. In a word, if you really need a chopper, but there is no money to buy it, there is only one way out - to make it yourself!

Step-by-step instructions and nuances of work

1. The saws are mounted on an axis, the diameter of which is determined by the mounting diameter of the disks (20mm). A stud with an M20 thread is suitable for this. Accordingly, washers and nuts of the same diameter will be required.

Saws mounted on the axis of the future chopper

If we install the discs on the pin close to each other, the knife will not work. And here's why: the width of the saw teeth is greater than the width of the blade itself, so when rotating, the teeth will cling to each other. To prevent this from happening, it is necessary to separate the disks a short distance. This can be done as easily as possible using homemade washers that you can cut from thin plastic. Their number should be 1 piece less than the number of circular saws.

2. A pulley is put on the stud axle (from a VAZ generator or from a pump). To rotate the axle, two VAZ intermediate shaft bearings with an internal diameter of 20 mm are also used.

3. A frame is welded from profiled metal pipes onto which the walk-behind tractor rod is attached. The engine is mounted on the frame so that it can be moved relative to the circular saws. This is necessary to change the tension of the drive belt if necessary.

An axle with circular saws is attached to the frame

4. For ease of use, a thrust block made of metal profile is attached to the frame, against which branches and stems will rest when crushing.

5. A metal casing must be put on the cutting unit, which is welded from sheet metal or cut from galvanized steel. To be safe, it is better to use the first option.

It is better to make the casing from sheet iron - it is more reliable!

6. Another hopper with a socket is attached to the top for loading the material to be crushed. There are no special requirements for this part, so most often it is made of flexible galvanized steel.

The receiving hopper is easy to make from galvanized steel

Washing machine peeler

Before making a crusher, you need to decide on the volume of the working chamber and familiarize yourself with the drawings. They will help you understand the design of working units and possible fastening of parts. You can find detailed diagrams on thematic forums.

The most important thing for a corn cob chopper is a reliable and durable base to which the hopper will be attached.

It can be made from a metal corner or wooden blocks. The hopper is made from the body of a washing machine. A magnetic block for turning the engine on and off is mounted on the outside of the bunker.

A cutting disc is placed inside the grain crusher, in which small holes are first drilled. The diameter of the holes should not exceed fourteen millimeters. You should also weld several teeth onto the disk, the height of which is about eight millimeters. From the bottom of the working chamber, perpendicular to the disk, two plates, each two centimeters wide, are attached by welding, and a small rubber scraper is attached to them. The role of the scraper is to direct the grains falling out of the cobs. The chopper flange is attached to the motor shaft.

A small hole is made on one side of the working chamber of the corn crusher, under which a tray for ready and clean grain is attached. On the opposite side, make a larger hole to remove empty corn cobs. The working chamber of the chopper must have a lid with a lock.

For a homemade shredder, a motor from a washing machine or vacuum cleaner is suitable. The power will be enough to process raw materials, but such a device will not consume much electricity.

Tips and tricks for making

Basic recommendations that are followed when making a peeler:

It is advisable to prepare a drawing before starting work and carefully consider how all the parts will be secured. This allows you to select all the required material and tools.
The holes in the tank for feeding cobs and receiving grain are made with doors so that nothing can fly apart.
It will be more convenient to work if you provide a tray for unhusked corn.
If the engine is high-power, an emergency power outage is required.
The hole for removing recycled materials is made so that a bag can be put on it. This device will speed up the work several times.
To make the device more convenient to transport, small wheels are attached to it.
