AXIAL-ROTARY THRESHING AND SEPARATING APPARATUS Russian patent published in 2006 - IPC A01F7/06 A01F12/18 

FIELD: agricultural engineering, in particular, equipment for threshing of farm crops.

SUBSTANCE: apparatus has rotor and deck positioned for performing angular vibrations around axis of rotation of rotor. Deck vibrations are provided by means of unbalancing mechanism equipped with drive and mounted on deck. Deck vibrations allow speed of releasing grain from heap under threshing process to be increased owing to imparting sign-variable pulses to heap.

EFFECT: increased efficiency due to enhanced release of grain from heap.
