Grass, growing everywhere in abundance, can becomean excellent addition to the diet of poultry or livestock. However, without special adaptation here can not do. The grass grinder can significantly simplify this laborious procedure, which will also improve the quality of the resulting final product, greatly facilitating the tedious process of grinding.
In the subsidiary farm this device is needed forgrinding of dry herbs, which are used for feeding animals. That's why many farmers who have a small farm, prefer to have at hand this useful machine - grass shredder forage.
The principle of its operation is very similar to a food processor. Sharp knives, mounted in a cylindrical body, rotate with great speed, lightning crushing straw, grass, hay.
Grinder Grass copes with any source product in a matter of seconds.
Straw or dry grass, which you need to grind, are put in the funnel, which is located on top, and the resulting trash leaves the hole located at the very bottom, which is closed by a box.
Many private traders, who have a small number of livestocklivestock or poultry, prefer to construct a grass chopper with their own hands. For this, everything that is at hand, for example, the case of an old vacuum cleaner, is used. The only requirement is the presence of holes in the body from above. Some even manage to adapt an old saucepan, the main thing is that the shape should be cylindrical.
The motor, which is inserted into the grinder of grass, should have a power of not less than 180 watts. Only in this case it will effectively cope with the work.
From the motor you need to separate the pulley, which is not needed, and then the engine is attached to the container at the bottom with the help of pins, which will pull it together.
The bushing on which the knives will be fixed can be made on a lathe. The main thing is that it should have a cylindrical shape and a height of not more than forty centimeters.
The knives are fixed with the help of usual water nuts with a diameter of up to 32 mm.
A thread is made for the nuts on the cylinder. To fix the engine on the shaft in the cylinder, you need to drill two seven-millimeter holes, inside of which a thread is made for locking bolts.
Knives made with the help of a Bulgarian from the canvassaws, put on a square, which is obtained by removing the faces on the top of the cylinder, so that a square is formed. Their width is selected, based on the degree of stiffness of the fabric, so that the deflection during operation is excluded. The shape of the knives is of no decisive importance, the main thing is that they are located as close to the bottom of the container, approximately at a distance of ten millimeters.
The support platform of the unit is made ofrectangular profiles, which is a pyramid with a truncated top. Its dimensions are determined based on the size of the container in which the finished product is already collected.
Grass shredder, self-made or bought inspecialized shop, can crush and grind not only grass, but also various other wastes, including root crops for livestock. The main thing is to correlate the power of the motor, the strength of the knives with the material to be crushed.
