ORGANIC FERTILISER SPREADER Russian patent published in 2014 - IPC A01C3/06 

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machinery industry, in particular to devices for the surface distribution of solid organic fertilisers. The spreader comprises a body with a conveyor mounted on the chassis, a grinding body, a guide plate, and a distribution rotor. The distribution rotor is located horizontally across the width of the body. The distribution rotor is made in the form of a drum, the outer surface of which is made in the form of two truncated cones docked to each other by the large bases. On the drum surface the blades are mounted uniformly along the helix at various angles relative to the axis of rotation of the distribution rotor.

EFFECT: implementation of the spreader ensures a uniform fan distribution of fertilisers and increase in the width of the working area of fertiliser application on the field surface.
