Claims
- 1. An arrangement for uniform distribution of an agricultural product on reciprocating transporting and cleaning organs of a sieve conveyor of a self-propelled harvester-thresher operating on an inclined surface, the sieve conveyor including a sieve box wherein swinging direction and thereby transporting direction of a transported product is changeable depending on a lateral inclination of the transporting and cleaning organs, the arrangement comprising a lower sieve secured to said sieve box and an upper sieve arranged in said sieve box and being swingably suspended above said lower sieve, means linked to said upper sieve to impart a movement in transporting direction to said product, and position adjusting means linked between a lateral side of said upper sieve and a wall of said harvester-thresher to change lateral position of said upper sieve relative to said sieve box in dependence upon an inclined position of the harvester thresher during threshing on an inclined surface, thus changing the direction of a movement component of the product transversely to said transporting direction.
- 2. An arrangement as defined in claim 1, wherein said position adjusting means includes slot-like openings formed in a side wall of said sieve box and in the wall of said harvester thresher, said slot-like openings sloping at an acute angle relative to said lower sieve, elongated holders fixed to said lateral side of the upper sieve and passing through said slot-like openings, and an operating means linked between said side wall of the harvester thresher and said holders to displace the same in said slot-like openings in response to position changes of the harvester thresher about its longitudinal axis.
