ABSTRACT:
A hopper gate and pneumatic actuating mechanism for controlled discharge of bulk materials from a bottom-unloading vehicle are described. The hopper gate comprises an arcuate closure plate pivotally mounted by wedge shaped end plates below a rectangular hopper opening, said hopper opening having one edge defining the end of a hopper end elevated higher than the opposed edge defining the other hopper end wall. The pneumatic actuating mechanism comprises a pair of opposed air bags selectively expanded by an air supply and operatively connected to the closure gate by a linkage system for opening and closing the gate.
