Step-by-step assembly: a vibratory plate with their own hands using a gasoline or electric motor
Compaction of soil, a layer of backfill or concrete castings during construction work requires special equipment. In private construction, there are often problems associated with deformation or settling of the foundation.
The cause of these events is poor compaction of the layer of sand backfill. According to the technology, the density should correspond to the condition of a long-used country road. Checking the quality of ramming is usually done by walking on the compacted area. if no footprints are left, the work is done at the proper level.
Tamping soil is not only required on critical areas. The normal laying of tiles on garden paths requires the creation of a layer of sand cushion, which also requires a maximum degree of compaction, otherwise the coating will begin to fail and move apart. It is impossible to achieve high quality of work by hand, and the vibratory plate comes to the rescue.
For home use, not everyone can afford to buy a ready-made device, since the cheapest model costs up to 20 thousand rubles. rubles. People who can operate with a plumbing tool and welding inverter, prefer self-made vibratory plates that save the budget and bring the desired result.
Vibratory plate: varieties and their features
By and large, all modern rammers are arranged similarly and do not differ from each other. the only difference may be observed in the type of the drive used to operate the tool, as well as some design features. For example, in the presence of reversible motion. let’s deal with it to begin with, but first we need to understand, due to what this tool moves over the tamped plane. You wouldn’t think that the operator would move such a heavy tool by hand. so the builder won’t be long enough. The operator only directs the vibratory plate, and it moves by means of slight vibration, thanks to which the process of tamping is also carried out. the plate as though nudges itself in the right direction.
But back to the reverse, which is very useful because you don’t have to reverse it when you’re working. They are dragged back and forth, switching modes, changing the direction of the vibration, which makes them go either forward or backward.
In addition to reverse, as mentioned above, vibratory plates can differ in the type of drive. in this regard they can be divided into three groups.
- Electric vibratory plate. This kind of rammer is tightly bound to power lines. if you plan to work far away from them, it is better not to buy such a tool. Or buy only in combination with an electric power generator.
- Gasoline vibratory plate. This is by far the most popular and cost effective in today’s market. As a rule, in terms of price it is in the middle between electric rammers and diesel vibratory plates.
- Diesel vibratory plate. While almost equal to their gasoline counterparts, these vibratory plates are used less frequently, because they’re a little more expensive.
VIBRATING TABLE. I make a with my own hands
There is a third indicator (or rather characteristic) of this tool. weight. According to this feature, all vibratory plates can be divided into four groups.
- Lightweight up to 75kg.
- Universal. their mass can vary from 75 to 90 kg.
- Medium. 90-140 kg.
- Heavy. 140 kg and more.
The mass can be called almost the most important characteristic of a vibratory plate. it is the mass and the size of the rammer that determine its capabilities. Let’s talk about it further, studying the question of how to choose a rammer?
Homemade gasoline vibratory rammer
The vibratory plate with gasoline engine differs from the electric model only in one component. the engine. Instead of the electric drive in this case a powerful gasoline engine is chosen that allows you to control the vibrator’s eccentric.
As the engine for the homemade machine, experts advise to take a single-cylinder motor manufactured by Honda.
The frame of the device with the vibrator and the plate is assembled in the same way as described for the electric vibratory rammer. Once it is ready, it will be necessary to fix the gasoline motor on it.
Some craftsmen manage to assemble a gasoline unit from a power tiller, removing all unnecessary things from it and assembling the necessary blanks for the vibratory plate on the frame. This modification simplifies all working operations and greatly reduces the assembly time. Another option of a homemade vibratory plate involves its making from a peorator, the device of which is very convenient for the stated purposes. Requires even less effort to resurface.
Classification of rammers by weight
Weight is an important technical parameter in addition to power. This is what you need to pay attention to when choosing a model of the device or when creating a rammer with your own hands. According to this parameter, vibratory plates are divided into four types:
Low compaction, used in agriculture, landscaping
High-frequency with low amplitude, used for thin layers of fine-grained soil and asphalt pavement
Applicable for thick layers of coarse-grained soils
Have a high amplitude of oscillation, are used when a high degree of ramming is needed
Useful tip! When choosing a vibratory plate, take into account that a heavy device is less maneuverable, but more effective. If the weight does not match the ground thickness and is less than recommended, it will take a long time to compact and use additional fuel or power.
Before you buy a vibratory plate, you need to decide for what purpose and where it will be used, this will determine its weight
How it works
The structure and operating principle of the device does not practically differ from analogues.
Its base is a working surface of steel or cast iron, in the center of which the vibrating mechanism is located.
It transmits vibrations to the material to be worked, and it, in turn, tampers. The driving force is gasoline or electric drive, the torque from which is transmitted to the vibrator by the V-belt drive.
The whole machine is assembled on a solid frame. The gasoline engine costs more, it is more durable and long-lasting. Has the advantage of self-contained operation.
But the electric model is lighter and more compact. Can be used in narrow spaces and even indoors.
What is needed to make a vibratory plate at home?
The most expensive part of a future vibratory plate is the motor, which will create the vibration. The site vibrators (IV-98B, IV-98E, IV-99B, IV-99E) will work fine. Such an engine will cost you only 5-8 thousand. Preferably the models operating from the usual 220 V network. This is due to the fact that not all areas are connected three-phase 380 V power. To vibratory rammer with their own hands was available in any place, choose the model IV-99E and IV-98E. Gasoline vibratory plate with their own hands will require a gasoline engine.
Sheet metal for the site. Is suitable a common sheet of 8-millimeter metal, or some large part of the machine. The main condition. the weight of this plate should not be less than 60 kg.
Two channel bars for attaching the vibrator to the plate.
Bolts, pipe cuttings, plastic wheels and soft elastic cushions for the vibratory plate handle.
In addition, you should stock up on tools: angle grinder, welder and plumbing tools.
Where to use vibratory plates?
Equipment for leveling surfaces is used in different areas where it is required:
- ramming of concrete mix, paving stones, paving tiles;
- compaction of sand, crushed stone and other bulk materials;
- Construction work in small areas. where there is no possibility to use heavy machinery.
Vibratory plates are often used for work in pits and narrow trenches. Most models are factory-equipped to travel backwards, making them ideal for use in areas with lots of obstacles. Vibratory plate with your own hands, as a rule, is deprived of such a possibility.
How the vibratory plate works?
Without understanding the design and scheme of action of the vibratory plate to assemble it is almost impossible. It consists of four basic units:
The main part of the device is a massive plate located at the bottom of the unit. Above the plate is a motor which is connected to the plate by a vibrator. To connect the motor and the vibrator, there is a clutch and a V-belt transmission, which transmits the torque to the vibrator. This, in turn, converts the force from a rotational to an oscillating force.The vibrations from the vibrator are transmitted to the plate, which compacts the surface, squeezing out the sand and moisture.
Instructions for making a vibratory plate
Before dulling, directly, to the very creation of the device, it is necessary to carry out preliminary work. The first thing to familiarize yourself with the features of the surface of the soil, which will be compacted. It is necessary to take into account the presence of crushed stone, gravel, etc. When performing complex works, it is necessary to use a plate with the maximum amplitude of oscillation. Also, it is important to consider the maximum permissible vibrating force of the structure, in order to know what index of compaction of the soil it is suitable for.
The basis for the device is a motor, which can be purchased in the store, but do not forget to consider its power. To build the base for the vibratory plate you can take a sheet of metal, more than eight millimeters thick, and a metal plate to create the sole, which is fixed at the bottom. Note that the weight of the base must exceed 50 kg and be perfectly level.
In order to prevent the slab from burrowing into the ground, bend its edges, using welding and an angle grinder.
Next, it is necessary to mark the surface area of the structure in order to attach the motor to it, using the bolts. Don’t forget to use a spirit level, to make sure it is perfectly level.
To make the finished vibratory plate easy to move, a handle is attached to it, using the same bolts, which are reinforced with nuts. Silentblocks, or other similar materials, are attached to the top.
The next step is to weld pipes for the water tank and hose to the base of the device, which is necessary for tamping.
The design is ready and can compact the soil up to 100 mm, and work for an average of 2.5-3 hours without intervals.
Before you get down to running your machine, be sure to check that there are no cracks, that all the parts are attached, and so on. д.
