FIELD: agricultural engineering, in particular, grain combine equipment.
SUBSTANCE: thresher has housing provided with side panels and incorporating beaters, threshing drums with concaves, straw walkers, and screen-air cleaner. Straw walkers are fixed on side panels by means of driving and driven crank shafts so that their inclination angle may be changed, and are equipped with mechanism for adjusting position of driving crank shaft. Position adjusting mechanism consists of left-hand and right-hand parts symmetrical with respect to one another, and is joined through bearings with ends of driving crank shaft of straw walkers. Each part of position adjusting mechanism comprises casing formed from corner portions and plates with radial slot and vertical slots, traverse with threaded stem, clip formed as plate with two bolts, and means for indicating inclination angle of straw walkers.
EFFECT: reduced grain losses behind thresher and improved versatility of grain combine thresher owing to the possibility of changing inclination angle of straw walkers depending on state of crop to be harvested.
