Abstract
A vibratory conveyor for transporting an object includes a deck defining a conveying surface for supporting the object, the deck having an inner edge and an outer edge. A housing has an inner wall coupled to the inner edge of the deck and an outer wall coupled to the outer edge of the deck, wherein an interior of the housing defines a conveyor chamber. An inlet air plenum is provided in fluid communication with a plurality of air distribution chambers positioned inside the conveyor chamber. A plurality of apertures is formed in the plurality of air distribution chambers, wherein the apertures are arranged in an air distribution pattern. An exhaust outlet fluidly communicates between the conveyor chamber and an air vacuum source. The conveyor may a catch floor disposed in a central chamber for receiving debris from an air stream. The vibratory force advances the debris to a discharge opening formed in the catch floor.
