The invention belongs to the technical field of scale type conveyors, and particularly relates to a scale type belt conveyor. The scale type belt conveyor solves the problems of existing continuous conveyors. The scale type belt conveyor comprises a rubber belt, a driving device and a supporting structure and is characterized by further comprising a round link chain used for fixing the rubber belt, the rubber belt is in the shape of a closed ring formed by lap joint of multiple rubber belt scales in the vertical direction, the scales are in the shape of arrow tail, and two end ports are oblique surfaces, with the upper portion of one end being oblique surface, and the lower portion of the other end being oblique surface; the center of each scale of the rubber belt is fixed to the round link chain. Any point of the scale type belt conveyor can operate in a bent mode and is adaptable to uneven grounds, conversion between linear movement and crooked movement can be achieved, and the scale type belt conveyor rotates on its own axis along with crooked traveling of a train when being installed on the train; the scale type belt conveyor has the advantages that belt conveyor operation resistance is small, and scraper conveyors are bendable, and the defects of large resistance, high noise and short service life of scraper conveyors are overcome.
