摘要:
The claimed utility model relates to agricultural machinery, in particular to threshing and separating devices of grain harvesters. The objective of the claimed utility model is to increase the productivity of the combine harvester, reduce crushing and injury of grain, simplify the design, increase the reliability of the mechanism, ensure a smooth rate of change in gaps at the entrance and the outlet of the threshing drum, as well as the possibility of adjusting the recommended clearances over a wide range. To achieve the specified technical result, the claimed utility model comprising a front concave section, a rear concave section, adjustable suspensions of the rear concave section, pivotally connected to the levers mounted on the torsion shaft, and adjustable trunnions installed in the inclined grooves of the front section of the concave and fixed on the thresher frame, a power drive, a bracket, an additional shoulder, pins, adjusting bolts, adjusting leveling axles, rods, while an additional shoulder is introduced into one of the levers from the side of the power drive installation, made in the form of separate plates rigidly fixed on the common axis of rotation of the lever, and the plates are interconnected by an edge passing through both surfaces of the plates, an additional shoulder located offset and at an angle other than 90 degrees relative to the other lever arm. The power drive at one end is fixed on the bracket, and at the other end it is fixed on the additional arm of the lever by means of cylindrical hinges, the bracket being movable along the grooves. The front and rear sections of the concave are pivotally connected by pins installed from the outside in the longitudinal grooves of the thresher frame and fixed on the inner side of the frame sidewalls by means of a bolted connection.Заявляемая полезная модель относится к сельскохозяйственному машиностроению, в частности к молотильно-сепарирующим устройствам зерноуборочных комбайнов.Задачей заявляемой
