UNIT FOR GRINDING ORGANIC FERTILISERS AND APPLICATION THEM INTO SOIL Russian patent published in 2015 - IPC A01C3/00 

FIELD: agriculture.

SUBSTANCE: unit comprises a hopper. In the hopper there are feeding horizontal conveyor, under which the grinding drum is mounted to the output side. The grinding drum is equipped with a toothed elements located along the helical lines. The toothed elements of the grinding drum are made lozenge, the front cutting edge of which is made parabolic with a sharpening angle of blade of 20-25°. Under the grinding drum the concave is mounted, having diamond-shaped toothed elements arranged in a checkerboard pattern. The sharpening angle of blade of the concave is 20-25°. The direction of the helical lines of the grinding drum is determined by the pitch t = Ma, where M is the number of bars of the grinding drum on which the toothed elements are mounted, a is the distance between the tracks of movement of the toothed elements of the grinding drum. The hopper is mounted on the frame, which is based on the wheeled mover. At the lower rear part of the frame on the hinge bracket with the help of leashes the harrow-hoe is mounted, to control which the hydraulic cylinders are provided, having the compression springs.

EFFECT: even distribution of organic fertilisers in the root zone of the soil is ensured, increase in its fertility and crop yields.
