INCLINED CHAMBER OF COMBINE HARVESTER Russian patent published in 2016 - IPC A01D41/12 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building and can be used to harvest grain crops. Inclined chamber 1 of combine harvester 2 includes mesh bottom 5, 6 conveyor for movement of grain and device 9 for removal of free grain allocated through holes of mesh bottom 5. Device for removal of free grain is made in form of a screw 10 with axis aligned with longitudinal plane of symmetry of inclined chamber 1 and displaced from its mesh bottom 5 at acute angle downwards. Solid bottom 12 is located under mesh bottom 5 and includes a chute screw 10.

EFFECT: sloped surfaces are located on sides of the chute, angle of inclination of sloped surfaces towards chute screw 10 in transverse direction increases from top downwards, which ensures formation of a narrow stream of free grains and possibility of transporting grain using an auger.
