A single chain scraper conveyor comprises a trough having first and second straight sections disposed at angles to each other and an intermediate curved section between and joining the first and second straight sections. The intermediate section has an inner curved edge and an outer curved edge, and the trough has an opening along the inner curved edge. An endless chain is centered in and movable along the trough, and it carries a plurality of flights which extend across the chain at spaced locations along its length. Each flight has an inner end which moves around the inner curved edge of the intermediate curved section during operation. A deflector wheel is rotatably mounted adjacent the intermediate section, and it includes a periphery that is parallel to the inner edge, on which a plurality of heads are pivotally mounted at spaced circumferential locations. The heads include surfaces having V-shaped grooves or receiving recesses into which the inner end of each flight may engage. When engaged, the flight is guided by the head in its pivotal connection to the guide wheel around the inner edge of the intermediate curved section.
