1. Field of the Invention
The present invention relates generally to devices for ejecting bulk materials from trailers. More particularly, 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.
2. Description of Related Art
Many bulk commodities and aggregates are transported throughout the United States by various types of trailers, including transport semi-trailers. Materials commonly moved include, but are not limited to, dirt, sand, rock, grain, etc. A truck operator is paid to move material from one location to another - the more material an operator can move in a given period of time, the more profitable the operator's business will be.
Many transport trailers used by operators are of the “self-unloading” type. Self-unloading trailers use one of several forms of “moving floors” to eject material from the trailer. Moving floors come in various forms including, but not limited to, reciprocating slat floors and conveyor belt floors. By their automation, these floors substantially decrease the time required to eject material from trailers compared to manual ejection methods. One time consuming drawback of a moving floor, however, is that after ejecting transported material from the trailer, some amount of residual transported material often remains on the trailer floor—material that must be manually swept or shoveled out of the trailer. Removing residual material from a trailer takes time, which increases the total transport time and reduces the operator's profit.
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 the moving floor is activated and material is ejected from the trailer, the invention “rides” along 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. After ejection is complete, the apparatus may be pushed back into place or pulled back into place via the tether bar. The invention may be used with most self-unloading trailers and does not require retrofitting of trailers for proper use. The “means for traversing the panel sweeper” may include a hinged door, a horizontally sliding panel, or a vertically sliding panel and gives the operator access to the trailer area behind the apparatus without the need to climb over the apparatus and risk injury.
