Abstract:
A plow conveyor adapted to convey abrasive scrap, comprising:an elongated trough having a flat bottom and sides; and a chip-motivating pusher bar in the trough that is adapted to reciprocate longitudinally and float laterally as the pusher bar reciprocates to move scrap along the trough, the pusher bar including a bearing component having a bottom surface that slidably engages the flat bottom for longitudinal and lateral movement, side surfaces extending up from the bottom surface, and an end surface forming corners with the bottom surface and the side surfaces, the corners each including a beveled bearing surface extending at an oblique longitudinal angle to each of the bottom surface and the side surfaces and the end surface to provide angled engagement with the flat bottom and the sides of the trough so that the corners cannot be sharpened to a chisel-simulating edge even after substantial wear, whereby wear on the trough is reduced.
