Referring to fig. 2, it can be understood that after the concrete is stirred, the interior of the machine body 1 can be cleaned by the sprinkler 5, and in order to clean the interior of the machine body 1 more completely, a driving assembly 56 for driving the support plate 51 to rotate by the rotation of the connection shaft 21 is disposed between each connection shaft 21 and the support plate 51.

The driving assembly 56 includes a driving disc 561, the driving disc 561 slides with the connecting shaft 21 and rotates synchronously, the periphery of the driving disc 561 is non-circular, and a fixing groove 562 for embedding the driving disc 561 is provided on one side of the supporting disc 51 near the driving motor 32.

An adjusting member 57 for driving the driving plate 561 to be engaged with or separated from the supporting plate 51 is provided at the outside of the body 1. When the inside of the machine body 1 needs to be cleaned, the driving disc 561 is embedded into the fixed groove 562 through the adjusting piece 57, and at the moment, when the driving motor 32 drives the connecting shaft 21 to rotate, the connecting shaft 21 also drives the supporting disc 51 to rotate through the driving disc 561 so as to drive the spray pipe 52 to rotate in the machine body 1, so that the water outlet 521 on the spray pipe 52 can spray water to various positions in the machine body 1, and the machine body 1 is cleaned more cleanly.

Referring to fig. 2, the adjuster 57 includes a first screw 571 screwed to the body 1. In use, a worker rotates the first screw 571 such that one end of the first screw 571, which is close to the supporting disc 51, abuts against the driving disc 561, and pushes the driving disc 561 such that the driving disc 561 is embedded in the fixing groove 562, thereby fixing the relative positions of the supporting disc 51 and the connecting shaft 21.

In order to enable the first screw 571 to abut against the driving disc 561 to be embedded into the fixed groove 562, when the periphery of the driving disc 561 is dislocated with the fixed groove 562, the driving disc 561 can be smoothly embedded into the fixed groove 562, and the outer side of the driving disc 561 is gear-shaped. When the first screw 571 is operated by the operator to push the driving disc 561 to move toward the fixed slot 562, the driving disc 561 abuts against one side of the supporting disc 51 and cannot be embedded into the fixed slot 562, and when the operator starts the driving motor 32 to drive the driving disc 561 to rotate so as to finely adjust the direction of the driving disc 561, the driving disc 561 can be embedded into the fixed slot 562.

The end of the first screw 571 is rotatably connected with balls, and the driving disc 561 is abutted with the first screw 571 through the balls, so that friction between the first screw 571 and the driving disc 561 is reduced. In order to avoid that when the driving motor 32 drives the driving disc 561 to rotate through the connecting shaft 21, the driving disc 561 slides out of the fixing groove 562 and cannot drive the supporting disc 51 to rotate, the first screw rod 571 can be always abutted on the driving disc 561 in the process that the driving disc 561 drives the supporting disc 51 to rotate, so that the driving disc 561 is prevented from sliding out of the fixing groove 562 under the inertia effect.

The adjusting member 57 further includes an electromagnet 572 fixedly connected to one end of the first screw 571 near the supporting disc 51, and the electromagnet is annularly sleeved around the ball. When the driving disc 561 is embedded into the fixed groove 562, and the driving disc 561 needs to be moved out of the fixed groove 562, the electromagnet 572 can be controlled to be electrified, so that the driving disc 561 and the electromagnet 572 are adsorbed together, at the moment, a worker reversely rotates the first screw 571 to move the driving disc 561 away from the fixed groove 562, and after a certain distance is moved, the worker de-energizes the electromagnet 572, so that a certain distance is kept between the driving disc 561 and the fixed groove 562, and the driving disc 561 is prevented from sliding into the fixed groove 562.

It will be appreciated that the height of the connecting shaft 21 may be set obliquely downward, so that the height of the connecting shaft 21 located inside the machine body 1 is higher than the height of the connecting shaft 21 connected with the driving motor 32, and the inclination angle may be 0.5-1 degree, so that when the driving disc 561 is located outside the fixing groove 562, it is not embedded into the fixing groove 562 again under the driving action of the adjusting member 57.

Referring to fig. 4, a discharge hopper 6 is further provided on the side of the body 1 near the ground, the discharge hopper 6 includes a hopper 61, and a valve 7 for closing the inside of the hopper 61 is provided inside the hopper 61.
