FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machine-building and can be used in devices for postharvest treatment of grain. The grain cleaner comprises a frame, two sieve boots, a drive shaft with bearing assemblies and two pairs of eccentrics. On the drive shaft two pairs of rotating loads of equal weight are mounted. The mass of rotating loads is such that their centrifugal forces balance from 30% to 70% of inertial forces generated by the movement of the sieve boots.
EFFECT: due to dynamic balance of the grain cleaner the processing efficiency of its operation increases by decreasing the deflection of the drive shaft.
