FIELD: agricultural engineering; grain harvesters. ^ SUBSTANCE: proposed thresher has housing with side panels and main beaters arranged in housing, and also first and second threshing cylinders with decks and guide grates, straw walker and air-and-screen cleaner. Shaped holes with shaped flanges for fastening second threshing cylinder with deck and guide grate are made on side panels of thresher housing. Thresher is made for re-adjustment of two cylinders one into one-cylinder thresher by removing second threshing cylinder with deck and installing beater-separator and beater separator deck in its place. Outline of shaped is equidistant to outline of shaped flanges. Outline of one of shaped holes of side panels exceeds outer contour of deck of second threshing cylinder. ^ EFFECT: enlarged operating capability and efficiency of device at harvesting different crops under different conditions owing to possibility of conversion of two-cylinder thresher into one-cylinder one and back. ^ 7 dwg |
