ABSTRACT:
A hopper bed for grain or the like is provided by the present invention. An opening in the hopper bed is closed by a flat plate structure which is mounted on first and second track components disposed on either side of the opening. A flat flange portion is coupled with the structure on each side in longitudinal alignment with a track component. Each flange portion has a plurality of closely spaced aligned openings which are also aligned with two spur gears. The spur gears are rotated to mesh with the gear track presented by the openings in the flange and thereby reciprocate the plate structure to close or open it. This construction precludes the accumulation of most foreign material in the gear track although any which does accumulate is cleaned out by the action of the gear itself moving in the track.
