Abstract

A vibrator feeder for causing piled up granular material to move down its own slope and off the edge of a shelf-like structure for unloading. The vibration is limited to material resting on a small edge, or lip, of the material support structure. This lip is formed as an extension of the floor of the bin. A series of rods supported from a vibration generator extend into the material resting on the lip. The vibrations disturb the angle of the repose of the material which feeds off the lip.
