A hydraulic cylinder for a drive unit assembly for a reciprocating floor slat conveyor system has a single tubular barrel divided into two chambers by a center head or plug. The center head is held in position by shrink fitting it into the barrel.

A grate bar (for forming a plank of a conveyor grate for transporting bulk material) includes at least an up-facing surface for supporting bulk material, a down-facing surface for supporting the grate bar on at least one grate bar rest, front end and rear-end sides, first and second profiled narrow sides. The first and second profiled narrow sides are complementary to one another and form a moving gap therebetween if and/or when the first profiled narrow side of the chosen grate bar is positioned adjacent to the second profiled narrow side of a neighboring grate bar (that is identical to the chosen grate bar at least with respect to the profile of the second profiled narrow side). The grate bar can be easily replaced if a front edge between the up-facing surface and the front-end side has a front edge curvature, a rear edge between the up-facing surface and the rear-end side has a rear edge curvature and the rear edge curvature is complementary to the front edge curvature.

A plastic splash guard hold down bearing for a moving floor conveyor has opposing hooks that clip onto an underlying support. The bearing presents a flat top surface for allowing a floor slat to slide back and forth as part of a moving floor conveyor. The plastic material and bearing construction is sufficient flexible to clip the bearing onto the support.

The present disclosure relates to end caps for extruded floor slats that are built into moving floor conveyor systems. The end cap has a portion that is inserted in the hollow end of an extrusion and is held in place by self-threading screws that thread directly into the material making up the end cap and the floor slat at the same time.

Reciprocating floor slat conveyor systems typically utilize floor slats that reciprocate back and forth while riding on bearings. The bearings sometimes have a curved J shape and, as a consequence, are commonly referred to as J bearings. The design disclosed here is an improved version of a J bearing that has segmented surfaces that are angled, rather than curved, relative to each other. Angled surfaces reduces voids between bearings and floor slats.

In a walking floor conveyor, an arrangement of panels lined longitudinally in a side-by-side fashion are organized into at least two correlating groups of panels. At least two panels within each group. Each panel grouping is propelled and retracted in a reciprocating manner, each by a hydraulic cylinder. The panels comprising wheel receptacles underneath the panels and at least one wheel fitted within a wheel receptacle to allow for forward and backward movement along a wheel support beam. These reciprocating panels supported by a series of wheel support beams, interior support beams and side support beams. These side support beams are at their tallest in the back and shortest in the front to provide a slant allowing for a flow of cargo and liquid runoff captured within a plurality of panel drains located between the panels towards a frontally placed auger designed for the assistance of cargo discharge.

The present disclosure relates to end caps for extruded floor slats that are built into moving floor conveyor systems. The end cap has a portion that is inserted in the hollow end of an extrusion and is held in place by self-threading screws that thread directly into the material making up the end cap and the floor slat at the same time.

According to an example aspect of the present invention, there is provided a hauling beam, which can be placed in connection with, a load to be moved, so that by moving the hauling beam the load can be moved. The hauling beam can be moved, for example, by dragging. The hauling beam described herein makes it possible to lift the load to be transferred on the rollers, wheels or rolls and to transfer the load by means of them. The hauling bean further comprises a spring retainer having a body with at least one mounting block attached to at least one of the parallel slats, a slide mounted on the body and a spring retained between the slide and a detent on the body, wherein the slide is attached to the support beam, a chain running as a loop around chain sprockets at each end of the hauling beam, one end of the chain being connected to the slide and one end connected to the body of the spring retainer, and an actuator configured to move one of the sprockets in the longitudinal direction of the chain.
