Today, there are many devices that greatly facilitate the daily care of the garden and the house. A wood crusher will not be superfluous . Almost everyone can make such a device with their own hands. With the help of such an aggregate, solid objects can be crushed.
Of course, someone might use a used wood crusher. Renting such an aggregate, however, will cost no less than creating a fixture with your own hands. Very often, the crusher is used to grind plastic, household waste, wood and stones, as well as to crush objects made of metal.
What are the crushers
Conventionally, crushers are divided into groups according to the type of use. They can be for grinding:
- plastics
- household garbage;
- a tree;
- metal;
- stone.
In addition, crushers are classified by size. The unit can be small - 0.02 m, medium - 0.1 m and large crushing - 0.3 m.
Based on the features, devices are:
- Knife devices.
- Devices are tiled.
- Crusher equipped with a cone-shaped hopper.
- Rotary knife machines.
How does a homemade unit
Recently, the Avito wood crusher has been in demand. However, this is not a universal unit. If desired, you can make a homemade device. To assemble it, it is worth understanding the principle of operation of such a device.
A homemade crusher works like a conventional meat grinder. The principle is quite simple. First, the material passes through the drum - the receiving bowl, and then enters the crushing system, where it is crushed very quickly. The compartment that grinds the garbage consists of several cutters and a mill. In this case, the performance of the unit directly depends on the power. However, this indicator should not be more than 2.6 kW. It is this power that the wood crusher has (used or new - it doesn’t matter).
What you need for work
To create a wood crusher, the following materials will be required:
- Saws. The thickness of these parts should be 0.6-0.1 m. They require 10 to 20 pieces for the unit to work normally. The more saws, the better will be the grinding of materials.
- Motor. It is best to use an electric motor. It works almost silently. A crusher with such a motor can grind debris in small quantities without harming the environment. Indeed, in the process of operation, the electric motor does not emit harmful substances. You can use the unit not only on the street, but also indoors. The main disadvantage is the dependence on power supply.
- Studs for attaching torches.
- Welding machine.
- Hopper and casing, which are made of galvanized metal.
- Washers and nuts.
- Profiled pipes made of metal, designed for the manufacture of the unit body.
DIY Wood Crusher
Making drawings is the first thing to do. Otherwise, you may get confused and assemble the unit incorrectly. Only after this can you start collecting the entire structure.
All saws should be installed on the already prepared axis. Their sizes should correspond to the sizes of torches. After installation, the discs must be secured with nuts and washers. In this case, some structural features should be taken into account. There should be thin washers between the saws. They will not allow the disks to touch each other with a point. The number of washers should be 1 less than the number of saws.
When the axles are locked and the discs are separated, a pulley should be installed. If such a part is not at hand, then it can be taken from a generator of a domestic car. In order for the stud to rotate normally, it is worth using several bearings with a diameter of 2 cm.
Frame manufacturing
The wood crusher is almost ready. With your own hands you can make a frame for the unit. For this, professional pipes will be required. They should be prepared in advance. To make the frame, the pipes must be welded together. Now you need to strengthen the design. To do this, it is worth mounting several profiles inside the frame. This will strengthen the mounting of the grinding unit and the hopper.
A sheet of metal should be welded to the finished frame, and then holes should be drilled in it for fastening the drum and motor. To make the crusher stand more stable, it is worth attaching 4 legs.
Now you need to install a disk that provides belt tension. It should be positioned so that the discs move freely. Such placement will allow you to freely adjust the belt.
So, how to create a wood crusher with your own hands. Making a case and connecting the saws is half the battle. Now you need to put the casing on the disc system. The hopper should be fixed above the cutting unit. That's all. The unit is ready.
What to consider
Now you know how to make a wood crusher with your own hands. Making the unit is actually not so simple as it might seem at first glance. There are several nuances to consider:
- Before assembling, it is recommended that you draw a drawing. This will clarify some aspects of the assembly of the structure, and also avoid even minor errors.
- To increase the productivity of the crusher, a larger number of saws should be installed. You can mount up to 25 drives. The thickness of each saw should be 0.1 m.
- If the crusher is designed to grind harder material than wood, then it is worth installing not an electric motor, but a motor block. Its power is much higher.
- To constantly not sharpen the discs yourself, you can install saws with alloy nozzles.
- So that the material is under pressure during the grinding process, a special beam should be fixed opposite the hopper, fixing it on the frame.
In conclusion
This is what a wood crusher looks like. How to take such a unit? This is easy if you can draw drawings and work with tools correctly. Of course, in the absence of experience, some difficulties may arise. It is worth noting that the crusher, created according to the instructions described above, is ideal for grinding not only fallen leaves and small garbage, but also for household waste and wood.
This design is considered more durable and reliable due to the saws installed horizontally. As for factory models, here the grinding system is mounted vertically. With this arrangement of saws, it is necessary to constantly monitor the humidity of debris and stems. Otherwise, the unit will break quickly. In addition, when manufacturing a wood crusher, you can independently choose an engine with the required power rating and the required number of saws.
