ABSTRACT:
A drag conveyor for particulate material is provided with an upwardly-curved bend section for conveying the material with paddles mounted on a continuous chain from a first level to a second, higher level. The paddles are provided with angled portions on opposite sides thereof which, together with the bottom of the trough of the conveyor and correspondingly angled portions of the conveyor above the trough, confine the paddles while traveling through the bend section. The angled portions of the paddles constitute a bearing surface in cooperation with the angled portions of the conveyor in the inside curvature of the bend section to maintain chain tension and keep the paddles in self-cleaning contact with the trough bottom.
