Abstract
Abstract A vibratable material-receiving member, carrying a baffle, is attached to the bottom of a storage bin to promote the discharge of material therefrom. The material-receiving member also carries arms extending upwardly into the bin, which arms carry the vibratory effect to material in the upper portions of the bin.
