A DEVICE TO MODIFY THE DISTANCE OR SEPARATION BETWEEN A THRESHING DRUM AND A THRESHING BASKET FROM A COMBINE.

摘要

1. Device for varying the distance between a threshing drum (10) of a combine harvester and at least one threshing basket segment (32) pivotally mounted on a threshing basket (18) by means of an adjusting element (42) connected to one end of the threshing basket (18), which adjusting element is movable against the action of a positioning force exerted by a spring (46), wherein the threshing basket (18) is pivotable together with one or more threshing basket segments (30, 32) by means of a further adjusting device (62) and the threshing basket segment or segments are pivotally mounted on a frame (28) of the threshing basket (18), characterised in that the downstream basket segment (32) has an arcuate extent which is smaller than the arcuate extent of the upstream threshing basket segment (30), covering a surface between 10% and 40% of the total threshing basket surface, while the downstream-located threshing basket segment (32) is supported on the frame (28) by the spring, which frame is pivotable together with the upstream-located threshing basket segment (30) by means of the further adjusting device (62).
