Self-propelled combine harvester

摘要

The present invention discloses a self-propelled combine harvester with a threshing device consisting of a threshing basket and of a threshing drum, the threshing basket being followed by a conveying floor which guides the threshed grain mixed with chaff to the winnowing device. This conveying floor consists of a plurality of individual part floors which are arranged above and offset relative to one another, thereby forming a plurality of fall stages, through which air is blown. A separation of the chaff from the grain thus takes place even before the grain/chaff mixture has reached the winnowing device. A conveying floor designed in this way results in a higher throughput and better cleaning.
