[0023] According to the present specific embodiment, the stirring mechanism 104 is fixedly connected to the tank cover 102, the tank cover 102 is fixedly connected to the mixing tank 101, the protective plate 108 is fixedly connected to the mixing tank 101, the vibration block 107 is fixedly connected to the output end of the vibration motor 106, the vibration motor 106 is fixedly connected to the mounting plate 105, the mounting plate 105 is fixedly connected to the mixing tank 101, the discharge pipe 110 is fixedly connected to the tank body 109, the feed cover 115 is rotatably connected to the cover body 111, each of the nozzles 114 is fixedly connected to the water pipe 113, the water pipe 113 is fixedly connected to the cover body 111, the water tank 112 is fixedly connected to the cover body 111, and the cover body 111 is fixedly connected to the tank body 109, each of the scrapers 120 is fixedly connected to the drive shaft 117, each of the stirring blades 119 is fixedly connected to the corresponding stirring rods 118, each of the stirring rods 118 is fixedly connected to the drive shaft 117, one end of the drive shaft 117 is fixedly connected to the output end of the stirring motor 116, and the stirring motor 116 is fixedly connected to the cover body 111. The vibration block 107 currently arranged is driven by the vibration motor 106 to remove residual impurities in the mixing tank 101 by vibration, thereby improving the impurity removal ability. The design structure is simple, and solves the problem that some residues of raw materials will still exist during the cleaning process, and long-term accumulation is prone to corrosion in the chamber.

[0024] Among them, the stirring mechanism 104 is located above the tank cover 102, the tank cover 102 is located above the mixing tank 101, the protective plate 108 is located on one side of the mixing tank 101, the vibration motor 106 is located on one side of the mounting plate 105, and the mounting plate 105 is located on one side of the mixing tank 101. During use, the staff starts the vibration motor 106, and the vibration motor 106 drives the vibration block 107 to rotate. The vibration block 107 is a solid ellipse. During each collision with the tank body 109, the residual impurities on the inner wall of the tank body 109 will be vibrated, thereby separating these impurities from the inner wall of the tank body 109. The setting of the protective plate 108 can reduce the direct damage of the vibration block 107 to the tank body 109, and is more vibration-resistant.

[0025] Secondly, the discharge pipe 110 is located below the tank body 109, the feeding cover 115 is located above the cover body 111, each of the nozzles 114 is located on the peripheral side of the water pipe 113, the water pipe 113 is located below the cover body 111, the water tank 112 is located above the cover body 111, and the cover body 111 is located above the tank body 109.

Each of the nozzles 114 works together to spray the water in the water pipe 113, thereby ensuring the humidity in the tank body 109 and also better promoting stirring and mixing and cleaning the inner wall of the tank body 109.

[0026] At the same time, each scraper 120 is located below the drive shaft 117, each stirring blade 119 is located above the corresponding stirring rod 118, each stirring rod 118 is located on the circumferential side of the drive shaft 117, and the stirring motor 116 is located above the cover body 111. Each scraper 120 rotates with the rotation of the drive shaft 117. Since each scraper 120 just touches the inner wall of the lower half of the tank body 109, the impurities remaining in the inner wall of the lower half of the tank body 109 can be effectively scraped out during the rotation of the scraper 120. The cooperation between the stirring blade 119 and the stirring rod 118 can better increase the contact area with the material, thereby better stirring the material.

[0027] In this embodiment, the vibration block 107 is driven by the vibration motor 106 to remove the residual impurities in the mixing tank 101 by vibration, thereby improving the ability to remove impurities. The design structure is simple, and solves the problem that some residues of raw materials will still exist during the cleaning process, and long-term accumulation will easily cause corrosion in the chamber. During use, the staff starts the vibration motor 106, and the vibration motor 106 drives the vibration block 107 to rotate. The vibration block 107 is a solid ellipse. During each collision with the tank body 109, the residual impurities on the inner wall of the tank body 109 will be vibrated, thereby separating these impurities from the inner wall of the tank body 109. The provision of the protective plate 108 can slow down the direct damage of the vibration block 107 to the tank body 109, and is more resistant to Vibration, the staff opens the feeding cover 115 to pour the material into the tank body 109, and then provides water to the water pipe 113 through the water tank 112, and each of the nozzles 114 works together to spray the water in the water pipe 113, thereby ensuring the humidity in the tank body 109, and also better promoting the stirring and mixing and the cleaning of the inner wall of the tank body 109, and each of the scrapers 120 rotates with the rotation of the driving shaft 117, because each of the scrapers 120 just abuts against the inner wall of the lower half of the tank body 109, so during the rotation of the scraper 120, the impurities remaining in the inner wall of the lower half of the tank body 109 can be effectively scraped out, and the cooperation between the stirring blade 119 and the stirring rod 118 can better increase the contact area with the material, thereby better stirring the material.
