In the utility model, the driving motor and the bearing drive the rotating rod to rotate, so that the asphalt concrete can be continuously mixed when driving the rotating rod and the mixing plate to rotate. When mixing, the mixing box rotates synchronously and quickly. The mixing centrifugal force generated by the rotation of the mixing box further increases the mixing efficiency, and the mixing speed is fast. At the same time, by setting the L-shaped rod and the scraper, under the fixing property of the scraper and the rotation of the mixing box, the asphalt concrete on the inner wall of the mixing box can be cleaned when the mixing box mixes the asphalt concrete, avoiding waste caused by sticking to the inner wall when discharging the concrete.
