[0006] Preferably, it also includes two cleaning structures, which are symmetrically installed through the inner wall of the support plate.
[0007] Preferably, the cleaning structure includes a connecting pipe that is fixed to the inner wall of the support plate. The upper end of the connecting pipe is fixedly connected to a water inlet pipe, which is connected to a water pump. The lower end of the connecting pipe is fixedly connected to a square cylinder. A damping shaft is rotatably mounted on the inner wall of the square cylinder. A baffle is fixedly mounted on the outer wall of the damping shaft. The baffle is mounted on the side wall of the square cylinder with a clearance fit. A diffuser is fixedly mounted on the inner side wall of the baffle.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By limiting the rotational stability of the motor shaft through the support cylinder, and by adjusting the cooperation between the structure, connecting plate, and base, multiple elastic stirring wires are assembled between the base and connecting plate to facilitate thorough mixing of the filling and ensure the mixing effect.

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-5This utility model provides a cleaning structure for the inner wall of a mixing machine, including a support cylinder 1, which is connected to the main body of the equipment. A motor shaft 2 is inserted into the inner wall of the support cylinder 1, and the upper end of the motor shaft 2 is assembled with a motor inside the main body. A support plate 3 is fixedly assembled at the lower end of the outer wall of the support cylinder 1. The lower end of the motor shaft 2 passes through the support cylinder 1 and is fixedly connected to an adjustment structure 4. A connecting plate 5 is fixedly assembled on the outer wall of the adjustment structure 4. The lower end of the connecting plate 5 is connected to a base platform 7 through multiple elastic stirring wires 6. The lower end of the adjustment structure 4 is connected to the base platform 7.
[0017] By limiting the rotational stability of the motor shaft 2 through the support cylinder 1, and by adjusting the cooperation between the structure 4, the connecting plate 5, and the base 7, multiple elastic stirring wires 6 are installed between the base 7 and the connecting plate 5 to facilitate thorough mixing of the filling and ensure the mixing effect. At the same time, by adjusting the structure 4, after mixing is completed, the elastic stirring wires 6 can be adjusted to deform as a whole and expand outward until they are in contact with the inner wall of the mixing drum of the filling machine. A cleaning cloth is then tied to the outer wall of the wires, and the motor continues to drive the elastic stirring wires 6 to rotate as a whole, which can effectively clean the inner wall of the mixing drum of the filling machine and ensure the cleaning effect. It is also easy to adjust and use, only requiring manual up and down movement of the mixing drum, which is simple and quick, and does not require a separate cleaning system, saving time and effort.
[0018] The adjustment structure 4 includes an electric telescopic rod 41, which is fixedly mounted on the lower end of the motor shaft 2. The outer wall of the electric telescopic rod 41 is fixedly connected to the connecting plate 5. The lower end of the outer wall of the piston rod of the electric telescopic rod 41 is screwed with a bolt buckle 42. The lower end of the bolt buckle 42 is fixedly mounted with a connecting rod 43. The lower end of the connecting rod 43 is fixedly connected to the surface of the base 7.
[0019] When adjusting the deformation of the elastic stirring wire 6 using the adjustment structure 4, first activate the electric telescopic rod 41. The electric telescopic rod 41 retracts the piston rod and drives the connecting rod 53 to move upward through the bolt buckle 42. At this time, the connecting rod 43 will drive the connecting plate 5 to move upward and compress the elastic stirring wire 6 to deform. Since the elastic stirring wire 6 is designed to bend outward, the deformation will only continue to expand towards the outer end until it can fit against the inner wall of the mixing drum. Then, tie a cleaning cloth to the outer wall of the elastic stirring wire 6 to effectively clean the mixing drum.
[0020] It also includes two cleaning structures 8, which are symmetrically installed through the inner wall of the support plate 3.
[0021] The cleaning structure 8 includes a connecting pipe 82, which is fixed to the inner wall of the support plate 3. The upper end of the connecting pipe 82 is fixedly connected to a water inlet pipe 81, which is connected to a water pump. The lower end of the connecting pipe 82 is fixedly connected to a square cylinder 83. A damping shaft 84 is rotatably mounted on the inner wall of the square cylinder 83. A baffle 85 is fixedly mounted on the outer wall of the damping shaft 84. The baffle 85 is mounted on the side wall of the square cylinder 83, and the baffle 85 and the square cylinder 83 are in clearance fit. A diffuser frame 86 is fixedly mounted on the inner side wall of the baffle 85.
[0022] By turning on the water pump, cleaning water is sent to the connecting pipe 82 through the water inlet pipe 81. The position of the baffle 85 can be adjusted as needed. Due to the setting of the damping shaft 84, the position of the baffle 85 can be adjusted arbitrarily and suspended. The diffuser 86 is made of plastic, which can disperse the water droplets and is lightweight. If the baffle 85 is located on the inner wall of the square cylinder 83, the water coming out of the square cylinder 83 will diffuse and spray out. If the baffle 85 is opened to the outer end at 90 degrees, the water will spray out in the form of a water column through the connecting pipe 82. Multiple options can be selected to ensure the cleaning effect of the mixing tank.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
