FIELD: agricultural engineering. ^ SUBSTANCE: sieve shoe has carcass with brackets on its front beam, and sieve. Carcass brackets are coupled through connecting rods to drive shaft. Hangers are connected to carcass through spherical pivot joints and to lower parts of levers through cylindrical pivot joints. Levers are made rotating and are connected through cylindrical pivot joints to brackets of thresher casing. Rotating levers on opposite longitudinal sides of carcass are pivotally connected through transverse tie-rods, which are pivotally connected through longitudinal tie-rod to double-acting hydraulic cylinder stem. ^ EFFECT: uniform distribution of heap on grid during operation on slopes owing to changing direction of vibrations and, as a consequence, improved conditions for separation of grain and reduced grain losses. ^ 1 dwg |
