A conveyor system for asphalt, concrete, aggregate and similar materials includes a plurality of conveyor flights and a pair of chains for moving the flights along a material supporting floor. Each flight includes end portions which attach the flight to the chains and a central portion having a hollow triangular cross section that extends substantially across the floor to define a narrow edge at the lower leading portion of the flight. The end portions support each flight with the narrow edge of the central portion facing and spaced from the floor. By this means the narrow edge and the spaced positioning of the edge relative to the floor prevent stones from accumulating between the flight and the floor. |
