A conveyor apparatus (10) for discharging bulk flow material (14) from a trailer (57) includes a drive sprocket assembly (34) at one end (12), driven by a motor (38), with a free, idler sprocket assembly (24) at the other end (11). Endless loop drive chains (40, 42) engaged over the two sprocket assemblies are spaced apart by transverse spacer bars (44) attached between the chains. An endless loop conveyor belt (52) is received loosely over the endless loop drive chains, covering the chains but leaving slack in the belt . When the motor turns the drive sprocket assembly, advancing the drive chains and spacer bars, the weight of the bulk flow material holds the conveyor bel t tightly down, against the chains and bars, creating friction to prevent slippage between the chains and the belt, thereby allowing the chains to advance the belt, and the bulk flow material thereon.
