ABSTRACT:
An apparatus for separating rocks larger than a predetermined size from a mixture of various size rocks utilizing a plurality of transversely spaced, inclined arms. The arms reciprocate back and forth, thereby expediting the flow of the smaller rocks into a hopper below and the larger rocks to roll down the inclined arms. The arms are resiliently supported by springs, and the driving mechanism is mechanically isolated from the arms to protect it from shock and vibration received by the arms.
