简介 A combine harvester (10) comprises a primary threshing unit (26) arranged to receive and thresh a harvested crop stream and a cleaning unit (48) which receives tailings, chaff and grain removed from the straw in the threshed crop stream. The cleaning unit comprises a shaking sieve (56) which separates tailings from the grain. The combine further comprises a re-thresher (78) to which the tailings are supplied, the re-thresher comprising a housing (81, 82) which bounds a passage, a re-thresher auger having flighting elements (77) mounted on a shaft (73), a plurality of threshing fingers (80) mounted on the shaft between the flighting, and a plurality of guide vanes (84) mounted inside the passage on the inner surface of the housing. The inner surface of the guide vanes present a profile which substantially conforms to the cylindrical swept volume of the flighting elements. Crop material is conveyed through the re-thresher by contact between the guide vanes and flighting of the auger in rotation.
