ABSTRACT:
A vibratory conveyor is provided that has only horizontal conveying motion acting on material lying in the plane of an elongate trough. A vibration generating apparatus is positioned selectively between the ends of the conveying trough. The vibration generating apparatus can be repositioned to any desired location along the trough to take advantage of the improved conveying action and the reduced deflection and twisting of the trough. The vibration generating apparatus includes a driving motor using a flexible drive to power two pairs of counter-rotating eccentric weights, with one pair being driven at twice the speed of the other pair so as to provide a motion on the material that moves the material along the plane of the trough with virtually no vertical component relative to the plane of the trough.
