<p>A drive mechanism for a shaker conveyor is disclosed in which a drive unit is supported on a mounting beam and has an output crank connected through a pull rod to a conveyor trough such that the puller rod undergoes movement in a plane substantially parallel to the direction of movement of the trough. The drive unit is rotatable relative to the mounting beam in a manner to selectively vary the acceleration characteristics of the conveyor trough, and has a self-contained internal lubricating system which provides improved quiet operation.</p> |
