Abstract
The present invention relates to a mechanical vibrating drive system for supplying a consistent, elliptical driving force to a conveyor trough. In a preferred embodiment of the invention, the vibrating conveyor has a set of vertical leaf springs connecting the conveyor trough to a vibratory frame, and a set of horizontal leaf springs connecting the vibratory frame to a stationary frame. The leaf springs amplify the motion initiated by a reversible motor, and the net result is a force output from the drive module that produces a uniform elliptical vibratory motion throughout the length of the conveyor trough. By reversing the motor, a symmetric elliptical motion for moving product in the opposite direction is generated without any further adjustments to the leaf springs.
