How to make a vibrating plate for soil compaction with your own hands

Purpose of vibrating plates

A vibrating plate is a mechanism designed to compact loose soils and bulk building materials. In addition, such a mechanism is widely used for vibration processing of semi-dry concrete mixtures and asphalt when constructing floors and paving surfaces. The use of such a tool is very effective when working on a small plot of land and in cramped spaces.

Homemade electric vibrating plate.

The construction of sidewalks, garden paths, driveways and parking lots near a private house using a vibrating plate is carried out much faster, while ensuring high quality of work. Compacting the bottom of the trenches when laying utilities eliminates their possible damage in the event of subsidence of loose soil. These and other advantages encourage many home craftsmen to make such equipment themselves and use it in construction work.

What is a vibrating plate?

Why do you need a vibrating plate?

The processes of compacting various loose bases are integral to construction work. For example, crushed stone, sand, soil and other similar materials.

Basically, these are the stages of preparation for pouring concrete, asphalt, laying tiles or building a foundation.

In order to mechanize the compaction process, so-called vibrating plates are used. The mechanism of their action is quite simple.

The device creates vibrations under the action of which small particles of the compacting layer are knocked as close to each other as possible, excess air is displaced and at the finish a flat base of the required density is obtained.

Buying such a car for yourself is quite unprofitable. A homemade vibrating plate will cost much more profitably.

Structural structure of the mechanism

A vibrator is mounted on a weighty platform, and a motor is installed above it. The last two nodes are connected by a coupling and a V-belt drive.

The rotational movements of the engine are converted into oscillatory movements using a vibrator and transmitted to a heavy platform, which in turn acts on the compacted surface.

The device's reverse function makes it possible to perform work in narrow trenches and pits.

The stove itself is made of steel or cast iron, preferably of good quality. Otherwise, the service life of the device is significantly reduced, and cracks appear on the surface of the base.

The size of the working surface of the slab affects the pressure exerted by the mechanism on the compacted layer. A slab with a smaller area compacts the soil better.

The density of the finishing layer depends on the vibration force. The higher it is, the better the material is compacted.

Vibrating plate configuration options

Nutrition classification

1. electrical,
2. diesel and
3. gasoline vibrating plate.

Electric. Electric is considered the most economical. This is exactly what they recommend collecting with your own hands for your own household.

Moreover, in terms of technical characteristics, vibrating plates with an electric motor are in no way inferior to their competitors. The only downside is the condition of having an accessible electrical network.

Gasoline. It will cost more than electric ones, but cheaper than diesel ones.

However, it will be more profitable to buy fuel for diesel engines, although the engine itself will be the most expensive of the three described.

Also, its disadvantage will be high noise, which reduces comfort at work.

The power of the installed motor must be sufficient to operate a heavy slab. Otherwise, the latter will load in bulk material.

Classification by weight

Highlight:

1. Lightweight slabs. Weighing 75 kg. For processing layers up to 15 cm thick. Such slabs are used for landscaping work, laying paving slabs, and damping polyurethane mats.
2. Universal plates. Their weight ranges from 75 to 90 kg. The maximum layer to be treated is 25 cm. They are used for landscape work, repair of road surfaces, including patching on asphalt.
3. Medium-heavy. Weight 90-140 kg. The thickness of the treated layer is up to 60 cm. Application - laying road surfaces in layers, backfilling trenches along the perimeter of the foundation.

Classification by direction of movement

According to the direction of movement during the compaction process, vibrating plates can be straight or reverse.

Straight lines can only move forward, and if a second pass over the compacted layer is necessary, such a machine will have to be turned around. And this, albeit small, is still a waste of time.

Reversible vibrating plates can move both forward and backward. They give higher performance. Typically, devices with slabs weighing more than 100 kg are equipped with reverse.

Additions to the package

An additional advantage would be if the vibrating plate is equipped with an irrigation system.

It protects the unit from sticking to the compacted surface. They should carefully protect the engine from water.

This way, small particles of bulk materials will not clog into the mechanism, and the machine itself will last much longer.

Advantages of a homemade tamping machine

The main advantage of a home-made vibrating plate is its low cost and the ability to perform high-quality and efficient work. The simple design ensures the reliability and durability of the mechanism. In addition, a homemade vibrating plate allows you to:

• Safely tamp any surfaces;
• reduce the amount of manual labor when performing work;
• improve the quality of footpaths and platforms;
• It is good to compact dry cement and semi-dry concrete mixtures when laying them.

Having a mechanism for compacting loose soils and bulk materials will allow you to carry out any amount of landscaping and exterior design work.

Review of purchasing options.

Proper care

Most walk-behind tractors are equipped with gasoline or diesel engines, therefore, having made a vibrating plate with such a drive, it will be necessary to provide appropriate care for the manufactured equipment. You can extend the life of a unit with a gasoline or diesel engine by observing the following rules:

• Before starting work, check the tightness of all fasteners.
• Regularly inspect the engine, check the fuel and oil levels.
• The spark plugs in the engine are inspected and, if necessary, cleaned of carbon deposits.
• For the durability of the equipment, you can use a rubberized mat, which is placed on the workpiece blade, preventing it from cracking when working with large crushed stone.
• Before each use of the equipment, the air filter is inspected and cleaned.
• Filling the gas tank is carried out exclusively with the engine turned off.
• It is not recommended to use a self-made vibrating plate on concrete, hardened asphalt and other hard and durable surfaces.

By making your own vibrating plate with an electric motor, you can significantly save on the purchase of professional equipment. This equipment has a reliable and simple design, and the use of a drive and base from a walk-behind tractor will significantly simplify its manufacture, so every homeowner can handle this work.

Mechanism design

The main working element is a heavy metal platform, which can be made of gray ductile iron or steel. The vibration effect on it is transmitted from a mechanical vibrator driven by a gasoline, diesel or electric engine.

Drawing of a homemade vibrating plate.

A durable handle is provided to control the vibrating plate as it moves across the work area. Additionally, the design may include a fuel tank or starting electrical equipment. The engine and vibration device are installed on a frame, which is mounted directly on the tamping platform.

The basic principle of operation of a vibration motor in a phone

The vibration motor for a telephone operates as an incorrectly balanced motor (electric motor).

In other words, the load is attached to the motor shaft not centrally, but slightly offset, which causes the motor to oscillate slightly when moving. By changing the load weight, engine speed, and the distance from the shaft to the weight, you can change the number of oscillations to the desired amount.

The vibration motor is the only moving part in the entire phone mechanism, which moves a small metal weight to sense vibration. And when the load is large enough, it negatively affects both the weight itself and the entire system.

Like any component of a mobile phone (as well as a computer), the vibration motor can break.

The main malfunctions of vibration motors (the vibration alert on the phone does not work):

1. The electric motor itself does not work;
2. In case of moisture or mechanical shock, the contacts and/or the upper cable are damaged. The top cable in a phone (smartphone) is a set of flexible contact elements that are responsible for turning the device itself on and off, as well as the presence and adjustment of sound.

Various contaminants can interfere with the operation of the motor if they come into contact with it or its contacts. Signs that the vibration motor for your phone needs to be changed will be a strong rattling sound during its operation, or a complete absence of any signals when there is an incoming call.

As a result of such a malfunction, not only the vibration signal will disappear, but the entire operation of the mobile phone system may also be disrupted, so you cannot delay in repairing the motor.

A vibration motor for a phone is an integral part that will help the user to always be in touch.

Therefore, if it malfunctions, the repair or replacement of the part should be entrusted to the service center specialists, since this requires almost completely disassembling the phone, and at home and without special skills and tools, it will be somewhat difficult to cope with such a task.

Use the services of specialists - this will help extend the life of the entire mobile device. The faster the vibration motor is replaced, the cheaper and easier it will be to repair the mobile device itself.

Making a tamping plate

The plate for the vibrating tamper can be manufactured at the factory or made by hand from a metal sheet with a thickness of at least 8 mm. A homemade vibrating plate should provide such a weight to the device that it will give a tight fit to the surface being treated.

Its dimensions should not exceed 800 x 500 mm, excluding the curved edge, which will ensure convenient operation and the ability to use the device without additional assistants.

A flat steel plate, when moving over soil or concrete mixture, will constantly cling to an uneven surface. To avoid this, the front and rear edges of the slab are slightly bent upward, resulting in a structure reminiscent of a sled. To do this, stepping back a little from the edge, you need to make a cut in the metal to a depth of 5-6 mm using a grinder and bend the strip. Repeat this operation on the other edge of the sheet. The contact line after the bend must be welded using electric welding.

Making a tamping plate.

To install the motor and vibration mechanism on the platform, you need to secure the support frame. It can be made from two installed pieces of metal channel. They must be installed parallel to each other transverse to the axis of the tamping platform. Drill mounting holes for the motor and vibrator in them and weld them with electric welding.

Vibration motors for phones: operating principle and innovative developments

Vibration motors for phones are devices that produce mechanical vibrations. When signaled by an incoming call, the miniature motor produces a vibration alert.

It is controlled by a PWM signal and is a microelectric motor with an eccentric on the shaft. The engine causes the load, which is attached to the shaft not at the center, but slightly to the side, to oscillate. The number of vibrations can be easily varied.

To do this, it is necessary to change the weight of the load, the distance from the load to the beginning of the shaft, or the engine rotation speed.

If you need to always be in touch, and frequent meetings and the company's corporate policy require the use of silent mode, the vibration alert function will help you always monitor incoming calls and not miss a really important contact.

The vibration alert rarely fails, however, if this happens, it is very easy to restore the phone’s functionality. You just need to order new vibration motors for phones in the online store.

Malfunctions of vibration motors most often occur due to dirt getting inside them, as a result of which the lubricant thickens and the motor begins to rotate weakly. To check the rotation speed of the motor, a voltage of 1.5 - 2 V is applied to it in any polarity. Depending on the test results, a decision is made whether the part can still serve or whether it needs urgent replacement.

Often, this happens when rattling occurs during operation of the vibration motor or as a result of mechanical damage. Malfunctions in the operation of the component may also be associated with incorrect operation of the cable to which the vibration motor is connected.

In this case, you cannot do without replacing the cable. As mentioned above, these micromotors are susceptible to dust, dirt and moisture entering the housing, as well as falls and shocks.

The latter lead to the contacts of the part mechanically moving away from the contacts on the motherboard, as well as to jamming of the part.

The current age of mobile technology involves improving existing parts every day. The clear leader in this area remains Apple, which successfully develops and improves existing technologies and clearly does not intend to stop there.

Back in 2009, Apple filed for a patent on haptic feedback technology. This technology involves the use of innovative vibration motors.

They will increase the accuracy and improve the quality of vibration responses, and will also be able to simulate vibration in certain parts of the body exactly where the screen is pressed and provide it with a feedback function.

When you press virtual buttons, the display not only vibrates, but also springs, which creates the effect of pressing a real button. The use of such electronic components on a mass scale is complicated by the thin size of mobile phones. However, as Apple successfully proves to us, nothing is impossible in this world.

Engine selection and installation

When making a vibrating plate with your own hands, diesel engines are usually not used. Yes, they are reliable and durable, diesel fuel is cheaper than gasoline, but these engines are too expensive and bulky for a small home machine. The most popular mechanisms are those with a gasoline internal combustion engine and with an electric drive.

The gasoline engine makes it possible to perform work regardless of the presence of a nearby energy source. This vibrating plate is in demand among small construction teams performing contract work on private development sites.

To carry out work within the personal territory, it is better to use a tamping machine with a 220V electric motor. It operates much quieter, does not require refueling, and the power supply can be easily provided through an extension cord that can be extended to any location on the site.

The electric motor is fixed to a welded channel using bolts and connected to the vibration mechanism using a belt drive. If the vibrator eccentric is connected to the motor with a rigid connection or mounted on a shaft, then the motor bearings will constantly fail due to vibration effects.

The structure of the model with a gasoline engine.

The center of gravity of the engine must be on the central axis of the vibration platform. If this is not done, then during operation the vibrating plate made by yourself will constantly move to the side and you will have to make additional efforts to keep it in the desired direction. Vibration-damping pads made of thick rubber must be placed under the motor feet.

DIY vibration motors

A vibration motor is essentially an incorrectly balanced motor. In other words, the load is not centered on the motor shaft, causing the motor to oscillate. The amount of oscillation can be changed by changing the weight of the load, the distance from the beginning of the shaft to the load, and the rotation speed of the motor.

A vibration motor can be installed on any object, which will cause that object to vibrate and move due to vibration. This is a quick and primitive way to make a simple robot move.

Vibration motors can be found in cell phones, pagers, game joysticks, and massagers.

If you don’t have this, then you can easily create a vibration motor yourself by attaching any unbalanced load to the shaft of any motor. A vibration motor can also be made by dividing the balanced load on the shaft into two parts.

Below are some simple examples.

Where can I get a ready-made vibration motor?

The main source of vibration motors are gaming joysticks with “recoil”.

Simply disassemble the joystick and remove the motor. It is ready to use.

Fan imbalance

A quick and simple way to make a vibration motor is to take a computer cooler and break off half of the blades with pliers. This will unbalance the fan and cause it to vibrate.

Adding an eraser

• Another simple way to make a vibration motor is to attach an eraser or piece of cork to the shaft of any DC motor.

Installing the Terminal Block

You can also make a vibration motor by attaching a terminal block to the shaft of any DC motor. The terminal block itself is heavy enough to cause the motor to vibrate, but you can experiment with clamping small objects like screws into the terminal block.

Adding a crocodile

You can also get a vibration motor by adding a crocodile to the engine. Find a motor with a plastic gear on the shaft. Place the crocodile on this gear and solder the two parts of the crocodile so that it does not jump off.

Vibration mechanism

The simplest device for creating vibration vibrations can be made from a piece of metal circle with a diameter of 40-65 mm. To do this, a hole with a diameter of 12-14 mm is drilled parallel to its axis along the entire length. It should be offset from the center by about half the radius. A metal rod of the appropriate diameter must be inserted into this hole and firmly secured with nuts.

Bearings or bronze bushings are installed on the same shaft-rod on both sides, mounted on racks welded to the channel. The height of the stands depends on the diameter of the vibrating roller. On the belt drive side, a pulley is attached to transmit rotational motion from the electric motor to the vibrator. Rotating at high speed, this roller with a shifted center of gravity will create oscillatory movements and transmit them through the racks to the vibrating platform.

Electric vibratory rammer circuit diagram.

You can use a factory-made vibration mechanism. This will provide a higher level of machine reliability, but will entail additional costs.

Homemade vibration motor for concrete

To compact the concrete mass in foundations and other reinforced concrete structures, surface-type or submersible vibration motors are used. For a surface vibrator, a vibration motor with a power of 1 to 1.5 kW, operating on a 220 V network, is suitable.

Its diagram is shown below, and it consists of:

1. Handles for holding, guiding and carrying the device.
2. Electric motor of sufficient power.
3. Power cable.
4. Eccentric unbalance.
5. Bases of the required size.

Professional models of vibration motors have an adjustable eccentric, which allows you to adjust the amplitude of vibrations and the force with which compaction is performed. The eccentric is fixed on the output shaft of the electric motor. To do this, a bracket is rigidly fixed to the shaft, and the unbalance in turn is attached to it with a threaded connection. By loosening the thread, you can adjust the position of the eccentric in relation to the motor shaft, thus changing the amplitude of the device.

Torque transmission

It is recommended to use a soft V-belt drive as a transmission to transmit torque from the engine to the vibration mechanism. It will ensure reliable rotation of the eccentric and protect the motor bearings from the effects of vibration.

It is recommended to use double-belt pulleys. This will give greater grip to the belts and ensure trouble-free operation in the event of a break in one of the belts.

To protect against possible injuries, the belt drive must be covered with a protective cover, and if this cannot be done, then a bumper guard must be installed.

How to assemble a vibrating plate yourself

Materials

1. Sheet of steel measuring 50x80cm and thickness 8 mm;

2. 
   An area vibrator and an electric motor for it, for example IV-98E. Some craftsmen build vibrating plates with a washing machine motor

3. Two pieces of channel up to 45cm long;
4. M10 and M12 bolts with nuts and washers;
5. Metal pipes 1.5 m long and 20-25 mm in diameter;
6. Shock absorbers.

Tool

1. Welding machine,
2. hammer,
3. grinder with cutting wheels,
4. drill and a set of metal drills for it,
5. set of wrenches,
6. tape measure and marker.

Control handle and vibration damping system

During operation, thanks to the front location of the eccentric and the resulting vibrations, the platform with the engine installed on it begins to move along the surface independently. But to set the correct direction of movement, a control handle is needed.

According to its design, it can have one or two inclined posts with a transverse handle-crossbar. It is recommended to install a vibration damping device in the upper part of the handle so that vibrations are not transmitted to the hands during operation. You can use springs as protection; the stand itself can be made of two pipes, one of which will go inside the other. The springs are fixed by steel rings installed on the pipes.

If you have the financial opportunity, then instead of a homemade spring structure, you can install silent blocks from a passenger car. This will provide sufficient vibration damping, and the structure itself will be less noisy.

Making a manual tamper

There are many options for making a rammer with your own hands. Some people make massive structures entirely made of iron, but in this case welding will be required. Others prefer to make do with improvised materials. Let's consider the best option for manufacturing a manual tamper for compacting soil, sand and gravel.

To do this, you will need a standard square beam of 100 - 150 mm. It should not be rotten or flaking.

Healthy! Some use round logs, but with the help of such compactors it is impossible to fully compact the base in the corners.

You will also need to prepare:

Making blanks

We will prepare the structure according to the drawing shown below.

After preparing everything you need, saw off the ends of the timber at a right, even angle, according to the dimensions. After this, it is necessary to use a plane to level the plane of the lower end of the block and remove chamfers of about 5 mm from the edges of the workpiece.

To avoid getting numerous splinters during the work, it is recommended to sand and polish the surface of the block.

Making a “shoe”

The next stage of creating a tamping tool with your own hands is making a metal “shoe” from a sheet of steel. To cut the plate we use the following template.

Or, you can simply install the beam with its lower end on a sheet of metal and trace it with a pencil.

After this you need:

Installing the handle

Having retreated 100 mm from the upper edge of the block, it is necessary to mark the center of the future handle. To do this, you must first measure the diameter of the shovel handle. Let's say it is 36 mm. To prevent the handle from dangling, you need to use a drill whose diameter will be several mm smaller than the diameter of the handle. It should be taken into account that the outer part of the hole in the bar will be slightly larger than the internal diameter, so during the work process it is necessary to periodically insert the handle into the bar and check how tightly it fits.

If the handle does not fit into the hole, you should never try to hammer it in with a hammer. Otherwise, the timber may crack and making a rammer for earth, sand and gravel with your own hands will have to start all over again. It is much easier to slightly plan the cutting to the required diameter.

After the hole is ready, you need to apply glue to its walls and install the handle. Excess adhesive can be removed with a rag. In order for the handle to hold tightly, you need to fix it with a long screw, which must be screwed into one of the sides of the beam.

When the glue gains strength, you can begin to use the tamper. It is best to store a homemade tool in a dry place, or you can pre-paint the workpiece to make it last longer. If necessary, the steel nozzle can be easily replaced with a new one.

Possibility of reverse movement

Movements of a homemade vibrating plate made as described above are only possible in one direction. Therefore, after walking a certain distance, you have to turn it around and only then move in the opposite direction. This reduces the speed of work and requires additional physical effort on the part of the operator.

Another drawing of a variant with a gasoline engine.

In order to provide the vibration machine with the ability to reverse movement, it is necessary to install a device that changes the direction of rotation of the motor. After its installation and connection, the vibrating plate will be able to move in two directions.

When the edge of the treated area is reached, the operator turns off the engine and starts rotating it in the opposite direction. The vibrator eccentric will also become reversible and provide the machine with a return movement.

How to make a simple vibration robot with your own hands!

If you are a scientist yourself or simply an inquisitive person, and you often watch or read the latest news in the field of science or technology. It is for you that we have created such a section, which covers the latest world news in the field of new scientific discoveries, achievements, as well as in the field of technology. Only the latest events and only verified sources.

In our progressive times, science moves at a fast pace, so it is not always possible to keep up with them. Some old dogmas are crumbling, some new ones are being put forward.

Humanity does not stand still and should not stand still, and the engine of humanity is scientists and scientific figures.

And at any moment a discovery can occur that can not only amaze the minds of the entire population of the globe, but also radically change our lives.

Medicine plays a special role in science, since man, unfortunately, is not immortal, is fragile and very vulnerable to all kinds of diseases. Many people know that in the Middle Ages people lived on average 30 years, and now 60-80 years.

That is, life expectancy has at least doubled. This was, of course, influenced by a combination of factors, but it was medicine that played a major role. And, for sure, 60-80 years is not the limit of an average life for a person.

It is quite possible that someday people will step over the 100-year mark. Scientists from all over the world are fighting for this.

Developments are constantly underway in the field of other sciences. Every year, scientists from all over the world make small discoveries, little by little moving humanity forward and improving our lives. Places untouched by man are being explored, primarily, of course, on our home planet. However, work is constantly happening in space.

Among technology, robotics is especially rushing forward. The creation of an ideal intelligent robot is underway. Once upon a time, robots were an element of science fiction and nothing more. But already at the moment, some corporations have real robots on their staff that perform various functions and help optimize labor, save resources and perform hazardous activities for humans.

I would also like to pay special attention to electronic computers, which 50 years ago took up a huge amount of space, were slow and required a whole team of employees to maintain them.

And now there is such a machine in almost every home, it is already called more simply and briefly - a computer. Now they are not only compact, but also many times faster than their predecessors, and anyone can understand it.

Final work

After assembling the slab, all metal parts must be primed and painted to protect against corrosion. Securely fasten the supply cable to the control handle to prevent the possibility of running over it. The engine switch must be located on the structure itself to provide an emergency stop during operation.

After this, the vibrating plate made by yourself must be tested. Freshly dug soil is best suited for this. Testing on bulk material will not allow you to test operation at full load.

As you can see, it is quite possible to make a vibration machine yourself. But for this you need to have basic knowledge and experience in plumbing and welding.

Advantages of homemade products

The cost of a device made independently is much lower than that of ready-made equipment. In appearance, it resembles a walk-behind tractor with a vibration motor. Quality and durability are ensured by the simplicity of the design. The efficiency of such a vibrator is no lower than that of a purchased one, and sometimes even higher.

Advantages of a homemade vibrating plate:

• Full compliance with the operating conditions for which it is manufactured allows you to perform the assigned functions with high quality.
• The owner chooses which vibrating plate to make: with an electric motor or an internal combustion engine.
• Everyone also worries about their own safety. Therefore, all the necessary protection systems will be provided and installed.
• Having your own device will allow you to choose the time and place of work according to your circumstances.

Design and principle of operation of vibrating plates

When carrying out construction and repair work, there is often a need for compacting and leveling bulk materials - sand, soil, gravel. To solve the problem at hand, a vibrating plate is used. Regardless of the model, it consists of several elements:

• frames;
• steel or cast iron plate;
• vibration installation;
• engine that powers the entire structure.

The operating principle of the technology is very simple. When the motor is turned on through a belt drive and clutch, it starts the vibrator, which transmits energy to the plate located at the foot of the installation. Frequent oscillatory movements pass into the soil, and loose particles move as closely as possible to each other.

Summary and price

Considering the features of the UAZ-3159 Bars, it is clear that, despite the improved interior, this is the good old UAZ - with all that it implies. Even the designation “luxury” changes little - Bars is a car for off-roading, but not for the highway.

On the one hand, there are frankly weak brakes, low speed and acceleration to 100 km/h in 20 seconds, huge gasoline consumption of 20 liters per 100 km and an interior that is inferior even to inexpensive imported SUVs. On the other hand, it has phenomenal cross-country ability, which has become better thanks to increased ground clearance, a wider track and geared axles.

Is it worth buying such a car for the city - definitely not, since for 790 thousand rubles - which is how much the new Bars UAZ costs - you can find many good options. But if you plan to drive it off-road, this will be the best option, since its cross-country ability is not inferior to, and in most cases superior to, imported analogues and costs less than them (when compared with new ones).
