ABSTRACT:
Previously belts, drag chains or screw feeders have been used to discharge a bulk material, such as wood pulp and the like, from a storage bin or hopper at the required rate. A problem with such feeders is obtaining uniform withdrawal of material from the full area of the bin, as typically some areas of the bin remain stagnant, and further there may be areas of consolidation and compaction of the bulk material against the walls of the bin. The present invention overcomes these problems by providing a discharge feeder in which an opening of selected width travels back and forth uniformly under the bin outlet. By a system of belts and pulleys, the surface of the feeder in contact with the bulk materials remains stationary with respect to the materials, while the opening itself traverses the length of the bin, allowing a uniform non-consolidating feed of the bulk materials.
