ABSTRACT:
In a trailer, a conveyor comprises a floor and two walls, each comprising a band and series of rollers. All the rollers of the walls are identical. The rollers of the floor are not. The first roller of the floor, at the discharge end, has a diameter larger than that of other rollers. The last roller, at the charge end, comprises cogs. The floor band is attached at both ends to a pad stream forming an endless conveyor with the floor band. The cogs fit into holes in the pads. The top floor band is of a rubber base and is dust tight; the bottom band is made of pads attached to each other by piano hinges. The cogs make the pad stream move alternatively from one end to the other, thereby causing the motion of the floor band towards the discharge end of the trailer and its return to the charge end. An angle iron joins the bands of the floor and of the walls to drag the band of the walls along with the top band of the floor. The discharge end roller, elevated, keeps the materials in the conveyor during transport.
