With the advent of spring, hot season begins for gardeners and gardeners, and they try to ennoble their infield. In order for fruit trees to bear fruit better, they are pruned. There remains a large number of branches and knots that are considered garbage. And only thrifty owners know how to efficiently use trimmings. Overgrown garden waste, usually consisting of twigs and mowed grass - fertilizer. However, this process lasts several years and requires a lot of space under the compost pit. To speed up the production of organic fertilizer and reduce it to several months, gardeners advise chopping wood waste. This will require a crusher for branches.
The device can process branches into wood chips or wood flour, from which, in addition to fertilizer, it is possible to create pellets for heating, putty and other compounds useful in the household. A garden shredder can be bought at a hardware or hardware store, but such an acquisition will require expenses. You can use the manual for the manufacture of the chopper.
A set of necessary materials
To assemble a homemade chopper, you will need:
- circular saw - 20 pcs.;
- engine (electric or gasoline);
- M20 hairpin with a set of fasteners;
- pulley with belt;
- bearings;
- metal pipe for the manufacture of a frame;
- stainless steel sheet for the hopper;
- plastic washer - 25 pcs.
Of the tools you need a hammer, a welding machine, a set of adjustable spanners and metal scissors.
Design
The main element of the device is the knife mechanism. Factory models are equipped with a metal disc with several cutting surfaces. However, with a large amount of work, the teeth quickly blunt and require frequent sharpening, which is not very convenient.
High performance in a homemade device will provide a carbide tipped saw.
It will take at least 20 such segments. The discs are equipped with sharp teeth designed to chop solid wood, so leaves, thin branches and roots can be easily processed.
In addition to the knife, the design requires other details that will drive the cutting element in motion. If you plan to process a small number of branches, it is better to use a unit with an electric motor. The garden electric shredder requires an electrical connection, and it is difficult if the work will be carried out away from the communication mains. The advantage of such models is low noise and lack of exhaust gases.. A gasoline unit has a much greater power, so it is needed where sawdust or shavings are made from rough source material, and the work itself is intense. When all the necessary spare parts have been prepared, you can proceed with the assembly of the shredder.
Assembly principle
For a type-setting knife mechanism, an axis is required, the diameter of which must correspond to the landing diameter of the disks (20 mm). A threaded stud, washers and nuts for it of a similar size are best suited.
The cutting discs are seated on the axis at a short distance from each other.
Tightly spaced teeth when cutting branches will cling. This is because the cutters protrude beyond the body of the web due to wiring. To avoid interference, you need to place homemade washers between the disks. Thin plastic material is suitable for their manufacture. It will take one puck less than knives. Then, a pulley is put on the axis (from the pump or the VAZ generator), and the pin rotates due to the bearings of the intermediate shaft of the same VAZ, having the same inner diameter (20 mm).
The basis of the crusher design is the frame, which is best assembled by welding from metal pipes. A walk-behind bar is hung on a welded frame. The motor on the frame is fixed so that it can be moved relative to the cutting unit. Then the tension of the drive belt changes freely. To make the machine comfortable in operation, on the frame you need to fix a piece of metal profile, which serves as an emphasis for processed branches. A protective casing covering the cutting block is cut out and welded from sheet iron. In the upper part of the construction, the homemade item is equipped with a bunker with a bell. It is cut out of galvanized steel. Garden waste will be loaded into this container for further crushing. To facilitate the movement of the chopper in the area, it can be equipped with wheels.
Homemade Machine Features
Garden shredder is a versatile household assistant, with which the processing of branches, knots, roots and other waste of natural origin will be easy. The garden will always have a well-groomed appearance. The knife mechanism easily processes branches and trunks of trees with a diameter of up to 10 cm, which is impossible for a factory unit, unless it is an expensive industrial equipment. Now you don’t have to waste time and sort garbage by selecting large branches. It is also important that a home-made assistant will chop even not enough dry branches. After all, the engine can be placed not on the same level with knives, but raised higher, protecting it from moisture.
Assembling the chopper according to the scheme, you can be sure of its high performance. All garden garbage falling into the crusher will be instantly pulled into the structure and quickly processed into a fine fraction. Properly assembled crusher is in no way inferior to expensive factory samples.
