FIELD: agriculture. SUBSTANCE: cleaning unit of grain combine harvester comprises oscillating board 2 arranged under thrashing-separating unit 1 which is followed by sectional straw walker 7 with upper and lower sieves 3 and 10, fan 8 and a device for collecting the products of thrashing. Dividers 4 installed on oscillating board 2 before upper sieve 3 in a longitudinal-vertical plane divide the flow of grain coming from oscillating board 2 into several flows and make it narrower. Sections 6 of straw walker 7 are arranged in symmetry with dividers 4 and are made narrower at the outlets of the flows of grain and small pieces of straw for delivering these flows between the flows of grain that came off the oscillating board 2. EFFECT: improved design. 2 dwg
