HARVESTING MACHINE Russian patent published in 2024 - IPC A01D41/08 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Harvesting machine includes combing unit (I) consisting of combing drum (1) with combing combs (2) mounted on it, threshing unit (II) and means for moving thrashed grain along tubular conveyor with rotating impeller with drive. Replaceable decks (3) with curvilinear ribbed surface of trapezoidal, wavy or triangular shape are located above combing drum (1) in the direction of movement of the combed heap. Between combing drum (1) and the threshing grain transfer device along the tubular conveyor there is blade beater (7) with cutoff flap (8). In threshing unit (II) above the threshing grain transfer device there is comb-type straw walker (9) with combs and a drive from a cam mechanism with reflecting shield (12) made of elastic material located above it. Comb teeth pitch does not exceed two dimensions of cam mechanism eccentricity T≤2A_ec, where T is the comb teeth pitch, mm, A_ec is the cam mechanism eccentricity, mm. On the rear wall of threshing unit (II) of the unit there is window (13) for removal of the long-stem mass.

EFFECT: providing minimum losses of combed grain and obtaining grain-chaff pile without content of long-stem mass with high density of grain-chaff pile.
