International ClassA01F 012/52AbstractA combine harvester (1) having a threshing and separating mechanism (8), a cleaning mechanism (9) disposed to receive threshed and separated crop material from the threshing and separating mechanism (8) and operable to separate tailings therefrom. Tailings rethresher means (44) are associated with the cleaning mechanism (9) for rethreshing the tailings separated therein, and tailings conveyor means (52) are provided for recycling rethreshed tailings from the rethresher means (44) to the cleaning mechanism (9). Above the cleaning mechanism (9) at a location offset from a discharge aperture (62) of the tailings conveyor means (52) a resilient screen (86) is provided which, in use, intersects the tailings flow and is operable to absorb the kinetic energy thereof which is imparted thereto by the tailings conveyor means (52). A deflector (72) is operatively associated with a forwardly inclined outlet portion (70) of the tailings conveyor means (52) to evenly spread and project the tailings against the screen (86). | |
