Multi-drum threshing mechanism for combine harvester, has scraper elements, which are engaged in intermediate space between teeth of conveyor drum, and are upstream to inlet area of separating basket

摘要

The multi-drum threshing mechanism has a threshing drum (22) which cooperates with a threshing concave (34), where the threshing cylinder is arranged in an overshot manner on a conveyor drum (26) acting with axially and circumferentially distributed teeth for conveying the crops. The scraper elements are engaged in the intermediate space between teeth of the conveyor drum. The scraper elements are upstream to the inlet area of a separating basket (36), where the teeth are adjacent to each other in axial direction.
