The invention discloses a novel concrete batching machine which structurally comprises a separating plate, a frame, an adjustable material guiding plate, a storage bin, a belt conveyor, a support frame, a triangular reinforcement frame, a mixed weighting hopper and a belt weigher; the belt conveyor is composed of a bend pulley, an adjustable roller, a front roller, a gear motor, a machine body, aguiding roller, a supporting leg and a belt; the adjustable roller is composed of slip-resistant lines, a roller, a movable support, a base and a tension bar; the belt conveyor is arranged at the bottom of the storage bin of the novel concrete batching machine; the adjustable roller is arranged on the belt conveyor; the adjustable roller drives the movable support to carry out angle adjustment byadjusting the tensile elongation of the tension bar, thereby enabling the roller to be capable of carrying out corresponding angle adjustment. Therefore, the adjusting function of the guiding chute ofthe belt conveyor is achieved.
