Combine harvesters for separation between crop grain and crop residue in processing process, has rethresher unit, which is arranged between threshing concave and cleaning unit for repeating threshing through threshing concave

摘要

The combine harvester (10) has an inclined conveyor (18), which is arranged downstream of a threshing unit with a threshing drum (20) and a threshing concave (21), where a cleaning unit (34) is provided for cleaning the deposited crop material through the threshing concave. A rethresher unit is arranged between the threshing concave and the cleaning unit for repeating the threshing through the threshing concave. The rethresher unit is arranged at the downstream end of a conveyor (30), where the rethresher unit has a frustoconical body for protruding threshing elements.
