Abstract

A combined harvester has a sieve box having a receiving plate for receiving the grain threshed by the combined harvester and at least one sieve receiving the grain from the receiving plate, a drive operatively connected to the sieve box for oscillating the same in a predetermined direction, and a device operatively connected to the sieve box for changing the direction of oscillation of the latter during movement of the combined harvester over a slope inclined in a direction transverse to a longitudinal axis and concomitant lateral inclination of the receiving plate and the sieve in dependence upon the lateral inclination to thereby obtain a uniform distribution of the grain on the receiving plate and the sieve by changing the transportation direction of the grain.
