FIELD: agricultural engineering, in particular, farm crop seed cleaning and sorting equipment.
SUBSTANCE: grain cleaning machine has frame, shaft arranged at an angle to horizontal plane and connected to frame by means of bearing units, pan fixed on shaft by means of bearing units, screen equipped with convex shields rigidly attached to screen sides and connected to shaft, mechanism adapted for connecting of pan to screen by balancing of inertial force and converting of vibration amplitude, and engine. Pin of said mechanism is attached to frame. Grain cleaning machine is provided with two pan movement restricting members made in the form of flexible plates fixed on frame, and device adapted for fixing of pan in extreme position and secured on frame. Engine is made asynchronous and single-phase, and is connected to shaft. Engine working winding is connected to ac circuit.
EFFECT: simplified technical realization of driving of grain cleaning machine.
