Arrangement for uniform distribution of agricultural products in self-propelled harvester threshers and harvester thresher provided therewith

Claim 1

An arrangement of a harvester thresher, comprising an arrangement for uniform distribution of an agricultural product on reciprocating transporting and cleaning organs of a sieve conveyor in inclined position, particularly for the uniform distribution of an agricultural product in a sieve box of a self-propelled harvester thresher on an inclined surface, wherein swinging direction and thereby transporting direction of a transported product is changeable depending on a lateral inclination of the transporting and cleaning organs, said arrangement including an upper sieve which is swingably supported in said sieve box so as to impart a movement in transporting direction to said product, and means linked to said upper sieve for changing the direction of movement of the transported product relative to a lateral side of said sieve box in dependence upon an inclined position of the harvester thresher during threshing on an inclined surface, and further comprising an elastic member by which said upper sieve is suspended on a machine housing, links engaging laterally said upper sieve and extending through a slot both in a sieve box lateral wall and through a slot in a harvester lateral wall, and position-changeable supporting pieces connected with an outer side of the harvester thresher wall and arranged so that said links are rotatably mounted on said supporting pieces.
