A grain combined harvester includes a reaper with a combing device, an inclined chamber with a beater feeding conveyer, a threshing and separating device made of units arranged in series: a grain cleaner and a device for additional threshing, a grain heap of which is delivered onto the middle part of an upper sieve of a cleaner by a conveyer, a grain tank. The device for additional threshing is made of several shafts on which corrugated disks are rigidly fixed with the same pitch. On the adjacent shafts the disks are shifted for one half of the pitch and rotate in the same direction. |
