MACHINE FOR GRINDING SOLID ORGANIC FERTILIZERS Russian patent published in 2017 - IPC A01C3/06 

FIELD: agriculture.

SUBSTANCE: machine is proposed, comprising a hopper, in which a feeding horizontal conveyor is located, under which a grinding drum equipped with toothed elements located along helical lines is located. The toothed elements are represented by grinding knives made in the form of plates repeating the circumference of the grinding drum, the front cutting edge of which is made in the form of a parabolic curve. Under the grinding drum, a shear knife is installed with an adjustable gap relative to the knife. The grinding drum is a hollow cylinder, on the side wall of which grinding knives are installed by means of rounded racks fixed with bolted connections, and the knives themselves are placed on the outer surface of the cylinder, so that the angle between the knife and the shear knife is equal to the cutting angle with a slip equal to 30…45°. Under the grinding drum on vibration dampers, a receiving tray and a vibrating distributor are mounted, behind which a milling cutter controlled by hydraulic cylinders is mounted by means of hinged brackets.

EFFECT: uniform distribution of organic fertilizers in the soil.
