APPARATUS FOR SEPARATION OF GRAIN HEAP IN AXIAL THRESHERS

FIELD: agricultural engineering, in particular, equipment used for fractional separation of grain heap in order to produce biologically valuable grain. ^ SUBSTANCE: apparatus has casing and housing of thresher with threshing drum and deck. Dividing shields arranged in pairs are pivotally mounted on front and rear tilt walls of thresher housing so as to define grain heap separation sections. Conveyor is positioned under thresher deck and is equipped with vertical dividing rib extending along its axis of symmetry. Seed receiver consisting of pair of interconnected funnels is positioned below conveyor, at its end, in the course of advancement of apparatus. Seed receiver is designed for advancement in direction perpendicular to axis of symmetry of conveyor belt. ^ EFFECT: increased efficiency owing to maneuverability of dividing shields within separation sections to provide the ability to change fractional composition of produced grain heap. ^ 2 cl, 5 dwg
