FIELD: agricultural engineering. ^ SUBSTANCE: grain combine has thresher with casing within which on frame and side panels are positioned beaters, two threshing drums, air-screen cleaner with grain and gleanings augers, straw walker, and hopper. Grain and gleanings augers of cleaner are joined to lower part of grain and gleanings elevators. Upper part of grain elevator is joined to hopper feeding device, and upper part of gleanings elevator is joined to additional threshing device. Distributing auger of additional threshing device is disposed under straw walker and above air-screen cleaner. Gleanings elevator, distributing auger and additional threshing device are driven by means of pulleys of rear counter-drive shaft and shaft of additional threshing device, and by means of chain transmissions from shaft of additional threshing device to distributing auger and elevator. ^ EFFECT: increased efficiency and reduced grain losses. ^ 3 dwg |
