COMBINE HARVESTER Russian patent published in 2024 - IPC A01D41/12 A01F12/44 

FIELD: agriculture.

SUBSTANCE: grain harvester contains an inclined chamber with a scraper conveyor and a threshing drum, between which a separating device is placed. The separating device is made in the form of a lattice consisting of parallel longitudinal strips connected at the ends, the cross section of each of which is oriented in a position close to vertical. A scraper conveyor is mounted above the grate. Each longitudinal strip of the grid is mounted on the bearings of two crankshafts with alternating movable and fixed strips in the transverse direction.

EFFECT: increased efficiency of the free grain separation process while ensuring the exclusion of the possibility of clogging the holes of the separating surface with components of the combed heap.
