US6415913B2 - Excited base conveyor system - Google Patents

A base excited vibratory trough conveyor includes a trough mounted on leaf springs to a base which is excited by a linear vibratory drive. The vibratory drive produces a linear force which is oriented to be perpendicular to the springs, and the linear force is adjusted to equal the reaction force of the springs on the base during the desired stroke.
