VIBRATION UNIT FOR SEED GRINDING Russian patent published in 2018 - IPC A01C1/02 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Vibratory unit for seed grinding is proposed, comprising a grinding drum, the inner surface of which is covered with a layer of rubber with an unloading window, working body in the form of a spring equipped with a device for changing the pitch of the turns, a hopper-dispenser, an unloading tray, mounted elastically on the base. Grinding drum is made in the form of an inclined with respect to the horizontal axis of a cylinder with a wavy surface along the perimeter and flat end walls of elliptical shape parallel to each other, placed perpendicularly or obliquely at an angle α to the horizontal axis of rotation of the grinding drum, but with preservation of parallelism to each other. In this case, the major axes of the ellipses of the end walls are rotated relative to each other by an angle β and along the entire length of the grinding drum is fixed a spring of conical shape with a flat section of turns.

EFFECT: installation provides increased productivity.
