realizing that the sleeve 6 can also do axial vibration on the surface of the transmission shaft 5 along with the rotation of the transmission shaft 5, then the sleeve 6 drives the stirring block 7 to rotate in the hopper 2 so as to increase the flow rate of concrete in the hopper 2, so that the concrete is quickly discharged out of the hopper 2 to increase the operation efficiency of the production line, meanwhile, the stirring block 7 moving axially along with the sleeve 6 can also intermittently impact the hopper 2 so that the concrete adhered to the inner wall of the hopper 2 quickly flows downwards, and the phenomenon that the concrete remained in the hopper 2 is adhered to the lug 307, the multi-line production is achieved by increasing the capacity of the hopper 2 to improve the production efficiency while increasing the position of the pulley 310. The pulley 310 is not clamped by concrete in the sliding process, and the sliding is flexible.

When the concrete mixer is used, concrete produced by a production line falls into the hopper 2 from the top, the motor 4 is started, the output shaft of the motor 4 drives the transmission shaft 5 to rotate, then the transmission shaft 5 drives the sleeve 6 to rotate through the clamping key, then the rotating sleeve 6 drives the stirring block 7 to rotate, then the stirring block 7 is grabbed to stir the concrete in the hopper 2, meanwhile, in the rotating process of the sleeve 6, the sleeve 6 and the top cylinder 8 are intermittently engaged and separated, because the top cylinder 8 is fixedly connected with the mounting frame 1, the top cylinder 8 forces the sleeve 6 to move rightwards on the surface of the transmission shaft 5 along with the rotation of the transmission shaft 5, then the sleeve 6 moving rightwards drives the clamping key 10 to move and then compresses the spring 11, and the compressed spring 11 provides a reset force to enable the sleeve 6 to move towards the direction so that the sleeve 6 is re-engaged with the top cylinder 8, therefore, the sleeve 6 vibrates left and right on the surface of the transmission shaft 5, then the sleeve 6 vibrates left and right and rotates to drive the stirring block 7 to vibrate left and right while rotating, then the stirring block 7 can contact with the inner wall of the hopper 2 while vibrating left and right, then the stirring block 7 can drive the hopper 2 to vibrate, so that concrete remained in the hopper 2 and adhered to the inner wall of the hopper 2 flows downwards rapidly and is discharged from the bottom of the hopper 2, when the tank car is full and the bottom of the hopper 2 needs to be closed, the air pump 301 is started, the air pump 301 extends to drive the connecting plate 302 to move rightwards, then the moving connecting plate 302 drives the bottom plate 303 to move rightwards, then the moving bottom plate 303 drives the lifting block 305 to move rightwards, meanwhile, the moving bottom plate 303 drives the connecting rod 309 to move rightwards, and then the moving connecting rod 309 drives the pulley 310 to slide rightwards in the track 311, the lifting block 305 sliding to the right then moves the projection 307 to the right, then the projection 307 moving to the right comes into contact with the bottom of the hopper 2, then the hopper 2 presses the projection 307 downward, then the projection 307 moves downward with the lifting block 305 and then compresses the diaphragm spring 306, then the projection 307 continues to move to the right, then when the projection 307 moves to the right under the hopper 2, the compressed diaphragm spring 306 provides an upward reset force which causes the lifting plate 305 to move the projection 307 upward, then the upwardly moving projection 307 abuts against the bottom of the hopper 2, and at the same time the compressed diaphragm spring 306 still provides an upward force to the projection 307 so that the top of the projection 307 fits tightly against the bottom of the hopper 2, thereby preventing the concrete from leaking at the junction of the bottom of the hopper 2 and the top of the projection 307. Meanwhile, the concrete on the surface of the projection 307 is left from the bottom of the liquid baffle 308 without contacting with the lifting block 305 when flowing, so that the lifting block 305 is ensured not to be stuck by the concrete, and the distance from the pulley 310 to the bottom of the hopper 2 is increased, and the pulley 310 is ensured not to be influenced by the concrete at the bottom of the hopper.
