First Claim
Patent Images
1. 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.

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.

4. A rock separator comprising:
-
a first set of parallel sorting arms having one of their ends interconnected through a first beam; a second set of parallel sorting arms having one of their ends interconnected through a second beam, the sorting arms in said first set being positioned in alternating spaced relationship with sorting arms in said second set; a frame; a crankshaft having first and second lobes, said crankshaft being driven by a source of rotating power; means connected to said arms at a point longitudinally spaced from said beams for supporting said arms on said frame; first and second links having one of their ends pivotally connected to a common point on said frame and their opposite ends connected, respectively, to said first and second beams, said first beam being spaced closer to said crankshaft than said second beam; a first drive rod having one end pivotally connected to said first link and the opposite end engaging the first lobe of said crankshaft; and a second drive rod having one end pivotally connected to said second link and the opposite end engaging the second lobe of said crankshaft, said second drive rod being longer than the said first drive rod. - View Dependent Claims (5)
