Abstract
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. Such balancing results in no stroke or movement of the base. A more lightweight base can thus be used without requiring that the base center of gravity be aligned along the center of gravity of the conveyor and the trough, or that the base be excessively heavy.
