Due to the speed difference, the rotating shaft 3 rotates relative to the barrel 20 inside the barrel 20, which can drive the spiral plate 4 to stir the concrete raw materials. When the stirring is completed, the hydraulic cylinder 8 extends, driving the barrel 20 to adjust the angle, so that the discharge port 6 is aligned with the construction site and then the discharge port 6 is opened, and the concrete is transported to the construction site.
