ABSTRACT:
A reciprocating slat type conveyor comprises a framework mounting a bed of longitudinally extending, laterally spaced apart first and second groups of alternating slats arranged for longitudinal sliding movement on the plane of the bed. Interposed between adjacent reciprocating slats is a fixed slat mounted immovably to the framework, each fixed slat having an upper material supporting surface that is narrower than the upper material supporting surface of each first and second reciprocative slat. A pair of double acting hydraulic cylinders are provided to move the groups of reciprocative slats longitudinally, one group of reciprocative slats being connected to one cylinder and the other group being connected to the second cylinder, so that adjacent reciprocative slats are able to move independently of each other while every other reciprocative slat operates in unison off the same drive, whereby all reciprocative slats can be moved in the forward direction simultaneously, and each group of reciprocative slats can be moved in the rearward, retracting direction independently of the other.
