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.

Dependent claims

A reciprocating conveyor, comprising:

(a) a base,
(b) at least one group of at least three elongated parallel slat members each of inverted U-shaped cross section defining an intermediate load-bearing support section and a pair of laterally spaced, downwardly extending side sections, the slat members being spaced apart laterally above the base for longitudinal reciprocation on a sequence wherein at least a majority of the slat members are moved simultaneously in the same direction to move a load longitudinally in a conveying direction and a minority of the slat members are moved in the opposite direction to retract the slat members without retracting a load, the adjacent side sections of adjacent slat members forming a pair of mutually facing side sections,
(c) an elongated fines removal trough underlying each pair of said mutually facing side sections, whereby fines collected in said trough are moved along the latter during simultaneous movement of the associated pair of mutually facing side sections in the load-conveying direction of the slat members, and
(d) an elongated seal member secured to one side section of each said pair of mutually facing side sections and extending laterally therefrom to a position closely adjacent the other side section of the pair.
