Abstract: A vibrating discharge apparatus for discharging particulate stored material from a surge or blending bin or the like, having a discharge end, a discharge apron defining an support surface near the bottom of the bin extending in a substantially horizontal plane along a conveyance path to the discharge end. The apron is directed along a downwardly curving convex apron path sloping downwardly from the horizontal plane at the discharge end and comprises a plurality of rigid elongated parallel transversely extending slat members each having a main slat body portion and a thin plate-like lip projecting therefrom to overlie the adjacent slat member.
