ABSTRACT:
In this scraper conveyor for loose bulk material the paddle-shaped conveyor elements are supported and guided in each case by means of supporting rollers of roller guiding arrangements with upper and lower bearing surfaces in the region of at least two longitudinal central planes of reference running parallel to one another. In order to prevent supporting rollers from becoming wedged in the roller guiding arrangments, the supporting rollers are provided on both sides of the appertaining longitudinal central plane of reference and each roller guiding arrangement contains an upper guide rail on one side of the longitudinal central plane of reference and a lower guide rail on the other side for the supporting rollers.
