Abstract
A shaker conveyor is operated by a drive mechanism using rotary motion converted to reciprocating motion by an eccentric, which provides for a shaker conveyor driven by a compact drive system.
Claims31
In a shaker conveyor system for conveying a variety of materials, comprising in combination, a frame means, a drive system supported on said frame means, and a linearly-reciprocating trough means supported on said frame means and connected to said drive system in a manner to affect reciprocating movement of said trough means, the improvement wherein said drive system comprises:
- a. a rotary power source;
- b. a transmitting means operatively connected to said power source for transmitting power from said power source to a converting means for converting rotary motion to reciprocating motion;
- c. said converting means operatively connected to a receiving means;
- d. said trough means being connected to said receiving means;
- e. said converting means comprises
- I. a fly wheel operatively connected to said power source by said transmitting means;
- and
- II. an eccentric secured to said fly wheel at an eccentric fly wheel end, said eccentric having a reciprocating plate end oppositely disposed from said fly wheel end;
- f. said receiving means comprising
- I. a reciprocating plate rotatably receiving said reciprocating plate end of said eccentric;
- and
- II. said reciprocating plate being operatively connected to a trough support.
A shaker conveyor system comprising a frame means, a drive means secured to said frame means, and a trough means secured to said drive means and to said frame means, wherein:
- a. said frame means includes;
- I. a frame base;
- II. at least two load roller supports secured to said frame base;
- III. a pair of load roller mountings secured to said load roller support;
- IV. at least one guide roller support secured to each load roller support;
- V. a load roller secured to each of said load roller supports and contacting said trough means;
- VI. a guide roller secured to each of said guide roller supports and contacting said trough means;
- VII. a drive mechanism base secured to said frame means;
- and
- b. said trough means includes;
- I. a trough having a top trough side;
- II. a pair of trough sides perpendicular to and above said top trough side as a part of said trough;
- and
- III. a bottom trough side adjacent said drive means;
- and
- c. said drive means includes
- I. a power source;
- II. a fly wheel connected to said power source and rotatably mounted on a fly wheel axle;
- III. said fly wheel axle secured to said drive mechanism base;
- IV. an eccentric secured at a fly wheel end to said fly wheel so that an eccentric axis is parallel to a fly wheel axis;
- V. a reciprocating plate end of said eccentric opposite said fly wheel end of said eccentric secured and bearing supported in a reciprocating plate for rotation within said reciprocating plate;
- VI. said reciprocating plate being bearing supported within a support means for said trough means;
- and
- VII. said bottom of said trough side being parallel to said reciprocating plate.
A shaker conveyor drive for use in affecting longitudinal reciprocating movement of a conveyor trough supported in a fixed guide way so as to be movable only longitudinally, said conveyor drive comprising, in combination, a fly wheel, means supporting said fly wheel for rotation about a first axis of rotation, an eccentric secured to said fly wheel on an upper fly wheel side, a reciprocating plate secured to said eccentric, said eccentric being eccentrically and rotatably mounted within said reciprocating plate and secured eccentrically thereto, and said shaker drive secured to a trough support for said conveyor trough, and said reciprocating plate rotatably and eccentrically mounted within said trough support.
