ABSTRACT:
The invention provides for the automatic and continuous cleaning of feed hoppers. A plurality of brushes extend transversely across the path of the upper flight of the horizontal conveyor in the bottom of a feed hopper. The brushes are spaced from each other and frictionally engage the teeth of the feed apron to convey good fibers to the feed apron at the end of the upper flight of the conveyor. A perforated plate is positioned beneath the lower flight of the conveyor and as the brushes traverse the plate on the lower flight they push accumulations of pepper trash through the perforations and into a removable pan beneath the perforated plate.
