Abstract
A combine harvester is disclosed with an infeed arrangement for receiving the harvested material, with a threshing device for degraining the harvested material, and with a cleaning device that is downstream from the threshing device for segregating the harvested material, and thereby a separating the grain from the non-grain components. The cleaning device includes has a sieve device that can rotate about a rotational axis with an at least sectionally sieve-shaped sieve jacket that extends in a peripheral direction around the rotational axis. Separating the grain from the non-grain components is performed by the cleaning device by superimposing a rotary movement and oscillating movement of the sieve jacket such that the oscillating movement is directed transverse to the rotational axis of the sieve device.
