VIBRATION MACHINE FOR SEED GRINDING Russian patent published in 2018 - IPC A01C1/06 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Vibration machine is proposed for grinding seeds containing a grinding drum, the inner surface of which is covered with a layer of rubber, 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 the cylinder with end walls of elliptical shape. End wall at the loading bushing is made flat and mounted not only at an angle to the axis of rotation of the grinding drum, but also to the axis of its cylindrical surface. End wall at the discharge sleeve is made conical and is mounted not only at an angle to the axis of rotation of the grinding drum, but also to the axis of its cylindrical surface. Through the entire length of the grinding drum, a spring of wave-like shape with a circular cross section of coils is fixed, covered with a layer of rubber.

EFFECT: invention enables increased efficiency.
