The motor 170 drives the cam 180 to rotate, and the cam 180 intermittently contacts the push plate 230, thereby driving the contact plate 231 to move, and the contact plate 231 contacts the protrusion. 314, thereby pushing the protrusion 314 to reciprocate along the guide column 311, so that the knocking contact 315 knocks the wall of the mixing drum 10, so that the concrete adhered to the inner wall of the mixing drum 10 falls to the bottom of the mixing drum 10, which is beneficial to cleaning the concrete on the inner wall of the mixing drum 10. When discharging the concrete, the air inlet pipe 150 is connected with the high-pressure gas tank through the air pump, so that the high-pressure gas is discharged into the connecting shaft 171. In the process of the motor 170 driving the connecting shaft 171 to rotate, the high-pressure gas is discharged through the exhaust hole at the end of the stirring rod 172, so as to be blown to the inner wall of the mixing drum 10, so that the concrete on the inner wall of the mixing drum 10 is blown to the bottom of the mixing drum 10, which is beneficial to completely cleaning the concrete.
