GRAIN CLEANER Russian patent published in 2021 - IPC B07B1/30 B07B1/42 

FIELD: agriculture engineering.

SUBSTANCE: proposed invention relates to agricultural engineering and can be used in machines for cleaning grain in all sectors of the national economy. The device of the grain cleaner consists of a frame, two sieve mills of approximately the same mass, located one above the other, and the sieve mills are attached to the frame using suspensions and racks, while the drive shaft for giving the sieve mills plane-parallel and antiphase vibrations is installed between them. The connecting rods transmitting movement from the shaft to the sieve box are connected to the upper sieve box in the area of its bottom and to the lower sieve box in the area of its cover. A counterweight is mounted on the drive shaft so that when the sieve mills are in the middle position, the counterweight is at the bottom.

EFFECT: increased dynamic balance of the grain cleaner.
