Threshing mechanism for a combine harvester and combine harvester with a threshing mechanism

摘要

The present invention relates to a threshing mechanism for a combine harvester, with at least three drums provided for the machining of the crop material, the one for threshing the harvested material is intended to include, as well as at least two of the threshing drum in a conveying direction of the crop material through the threshing mechanism downstream drums, wherein• the drums in each case have a diameter, wherein the diameter of the threshing drum is the greatest,• the drums to a in the conveying direction approximately concavely extending, rising, imaginary line are mounted.• the diameter of the to the threshing drum downstream drums in the conveying direction are successively smaller.The present invention also relates to a, in particular, self-propelled combine harvester with such a threshing mechanism, as well as a method for adjusting of the threshing mechanism.
