VIBRATORY GRAIN SORTING MACHINE

摘要

Disclosed is a vibratory grain sorting machine which comprises an assembly to be vibrated at least including a frame and at least one stack of sorting plate members. The assembly to be vibrated is pivotally supported on a base structure by a plurality of strut units. At least one of the strut units has a top end pivotally connected to a side wall of the frame and a bottom end pivotally connected to the base structure. Each of the remaining strut units has a top end pivotally connected to a bottom wall of the frame and a bottom end pivotally connected to the base structure. A vibrating device is connected to the frame to apply a force substantially toward and away from the center of gravity of the assembly to be vibrated, thereby angularly reciprocating the assembly to be vibrated, around the bottom ends of the respective strut units.
