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

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.

A rock separator comprising: a rigid frame; a first set of parallel interconnected sorting arms; a second set of parallel, interconnected sorting arms, the sorting arms in said first set being positioned in alternating spaced relationship with the sorting arms in said second set; means for supporting said first and second sets of sorting arms on said frame; a shock absorbing support table mounted on said frame, said support table having a mounting surface fixedly secured to said frame and a shock isolation surface resiliently supported by said mounting surface; and powered means for imparting a random-like reciprocating motion to first and second drive rods connected to said first and second sets of sorting arms respectively, said powered means being mounted on said isolation surface such that the shock imparted to said frame by said arms is substantially isolated from said powered means.
