Shredder for wood: manufacture

If from time to time you come acrossnecessity of trimming of trees, then you must face the task of storing thin branches. They can take up a lot of space. Some chop them by hand or use special shredders. The second option allows to achieve the result much faster, and the wood turns into small chips. A prefabricated unit is too expensive, so you can do it yourself.

Manufacture of disk grinders

If you decide to perform a shredder for a tree, then you will need the following materials:

• high-carbon steel;
• steel shaft;
• fasteners;
• steel sheet;
• pipes;
• two bearings.

When choosing a steel sheet, you should preferthe thickness of which is 5 mm, and also from 10 to 16 mm. The first version of the billet will go to the hopper and casing. High-carbon steel is necessary for knives, you can use for this purpose an automobile spring.

To weld the frame, you must stock round orprofile pipes. If you want to make a shredder for wood, you will need a 20 mm steel shaft. Bolts with nuts will serve as fasteners. The belt drive may or may not be installed if the crusher is equipped with an electric motor with a speed of 1500 per minute.

Manufacturing of shredder

Using thick metal, you must cuta circle whose diameter is 400 mm. In the center holes are made, where the shaft will be inserted. The shaft and pulleys are grinded on a lathe, at the ends of the shaft, the threads are threaded to fit the pulley and flywheel.

If you needed a shredder for wood and youdecided to make it yourself, then knives you can perform at home. If you can not cope with this, you can trust the case to the milling machine. From the steel sheet at the next stage, a protective casing is welded, which is connected to the hopper. The same material is used for the clip.

Assembling

Homemade chopper is a cutting mechanism,which is fixed on the frame. The latter can be performed in an arbitrary design. The drive motor is located in a convenient place, which will depend on the length of the belt. The fixation of the motor must be made sliding, so that the belt can be stretched.

Making a shredder for wood, you mustInstall the machine shaft on the frame. A pulley and a flywheel are fixed to it. The knives are screwed to the flywheel so that their angle of inclination is 30 °. Use for this you need bolts. In addition, steel pads are prepared.

Features of manufacturing a chipper with a matrix of saws

If you decide to make a shredder for woodwith your own hands, then you can use a working matrix, based on the saws. Assembly of the unit is much easier than the previous one, because there are fewer welding operations. For the assembly will need saws for wood from hard alloy. It is necessary to prepare sheet 2-mm steel, separating 5-mm washers and pipes for manufacturing the frame.

Assembly Features

After reviewing the drawings of the shredder for the tree, you canunderstand which design to choose. From the above-described parts, it is necessary to assemble the product, which is obtained by the method of a set of washers and saws on the shaft. On the sides, the elements are pressed with nuts. Washers are laid between the saws so that the thick cutting parts do not press against each other and do not move. The shaft presses the bearings and installs the clips.

Finally

When there is a lot on your gardentrees, then the chopper can be a good help in the farm. Acquire the factory model is quite expensive, so you can do it yourself. It will save you from circumcised branches that occupy a lot of space. The area of ​​use of sawdust and chips obtained is wide, because they can be used even for heating the house.
