ABSTRACT:
A reciprocating conveyor is formed of at least one group of at least three elongated slats of inverted U-shape spaced apart laterally for longitudinal reciprocation in such manner that all or a majority of slats move simultaneously in a load conveying direction and sequentially in the opposite, retracting direction. A seal member is secured to one side section of each slat and extends laterally therefrom to a position closely adjacent the facing side section of the adjacent slat. The fines of particulate material being conveyed as a load gravitate downward past the free side of the seal member and are deposited in a trough that underlies each pair of facing side sections of adjacent slats. As the adjacent slats move simultaneously in the load conveying direction, the corresponding pair of facing side sections move the fines in the trough in the same direction. This movement is enhanced by providing fines pusher members on the lower ends of the side sections of the slats.
