THRESHING AND SEPARATING APPARATUS Russian patent published in 2002 - IPC

FIELD: agricultural engineering. SUBSTANCE: apparatus has inclined feeding conveyor, two feeding spring-loaded and rubberized rolls and threshing rolls arranged in pairs behind feeding rolls. Threshing rolls are made in the form of shells with pins and are equipped with flexible working members, which are made in the form of elastic embracing shells provided with longitudinal semicircular projections and slots. At the site of maximal approach of each pair of threshing rolls, slot of one roll is arranged opposite projection of other roll. Pairs of threshing rolls and receiving rolls are positioned for mutual discrete shifting. Threshing rolls are mutually connected through synchronous transmission. Mass to be threshed is delivered by feeding conveyor to receiving rolls. Rubberized receiving rolls are spread apart to feed gripped mass to be threshed into space between threshing rolls. Mass to be threshed is subjected to multiple bending actions of threshing rolls. EFFECT: improved threshing quality by eliminating impact loads. 9 cl, 5 dwg
