ABSTRACT:
Apparatus for handling particulate material such as is stored in a hopper having an elongated throat opening closed by one or more gates. The gates are mounted at one end thereof from axially aligned rails which are preferably mounted outside the hopper on each lateral side of the throat opening. The other end of the gate is arcuately formed in axial cross section, and is supported on structure, preferably including rollers, bridging the throat opening transversely. As the gate is moved along the track, the other end moves upwardly and forwardly in the hopper, and will dig into and break up arches and rat holes and other formations within the hopper to promote flow through the gate.
