摘要: A combine harvester comprises an oscillating thresher pan (128;228;328) for conveying a chaff/grain stream rearwardly to rear edge from where the grain/chaff falls under gravity into cleaning unit (148;248;348). The unit, or shoe, includes at least one vibrating (150;250;350,151;251;351) onto which falls. comprising fan (52) generating airstream is directed through failing stream. pan, when in use, provided with damping surface damp bounce of kernels falling thereupon. In example, by sheet rubber (284,288).
