For use in a reciprocating floor slat conveyor system having formed slats made of steel, a gap filler for sealing the gaps between side-by-side steel slats includes a portion that extends upwardly into the gap, and a lower portion that is connected to one of the side-by-side slats. The gap filler is installed by pushing down the gap filler into the gap between slats.

A switching valve module which is part of a switching valve control system for use with reciprocating slat-type conveyors is disclosed herein. Disclosed herein is a switching valve module that includes an inner control valve and an outer control valve. A spool is positioned within the inner control valve and a spool positioned within the outer control valve. Movement of each the spool creates both a spool-type seal and a poppet-type seal between the spool and the respective control valve.

The present invention relates to a detachably attachable moving headboard trailer ejector and floor cleaning apparatus for use with a self-unloading trailer having a front end, a rear end, side walls, and either a reciprocating slat conveyor floor or a conveyor belt floor. The invention comprises, in one embodiment, a base, a panel sweeper, one or more panel sweeper support members, a means for traversing the panel sweeper, a tether bar, side flanges, and a base flange. In use, the invention is placed in the front end of a self-unloading trailer and the trailer is loaded with material; when material is ejected from the trailer, the invention transverses or “travels” along the top of the moving floor and pushes the material out of the trailer's back end. The rubber flanges ensure a snug fit within the trailer and keep post ejection residual material at a minimum.
