| description | A grain cleaning system for a combine harvester, comprises a frame supporting a grain pan and a sieve. The grain pan receives grain and chaff separated from the crop by a threshing mechanism and is reciprocable relative to the frame in order to separate the grain from the chaff and to propel the grain and chaff towards the sieve. The sieve is reciprocable relative to the frame and is connected to the frame by front and rear support arms and that are pivotably secured to the frame and to the sieve. In the invention, the front support arms have different geometries from the rear support arms such that when the sieve is reciprocated relative to the frame, the vertical component of oscillation is greater at the front end than at the rear end of the sieve. |
