Patent ID: 8657103

Claim:
An apparatus comprising: a frame; a continuous loop conveyor belt mounted on said frame, said conveyor belt having a first edge, a second edge, and a belt surface between said first edge and said second edge, said belt surface moving in a direction parallel to said first edge and said second edge, said first edge being positioned relatively higher than said second edge such that said conveyor belt is at an angle with respect to a horizontal ground reference plane and such that said conveyor belt slopes downwardly from said first edge toward said second edge; a sidewall connected to said frame, said sidewall being positioned adjacent said second edge, said sidewall being perpendicular to said belt surface and running parallel to said second edge along an entire length of said belt surface in said direction, said sidewall forming a right angle with said belt surface to prevent items from falling off said belt surface at said second edge; a plurality of rectangular fins connected to said belt surface, said fins being perpendicular to said sidewall and being perpendicular to said belt surface; and a vibrator connected to said frame, said vibrator producing and transmitting vibrations to said conveyor belt.
