A feeding mechanism 8 is provided on the tank body 1, and a weighing mechanism 9 is provided on the feed inlet 4.

[0023] Please see Figure 1 , Figure 2 , Figure 3 The feeding mechanism 8 includes a self-locking motor 81. The self-locking motor 81 is fixedly installed at the upper end of the tank body 1 and on the left side of the feed inlet 4. The upper end of the output end of the self-locking motor 81 is fixedly connected to a rotating shaft 82. The top of the rotating shaft 82 is fixedly connected to a turntable 83. Multiple uniformly distributed material cylinders 84 are fixedly sleeved inside the turntable 83. The top of the material cylinder 84 is provided with a feeding port 85, and the bottom of the material cylinder 84 is provided with a guide port 86. A solenoid valve is provided on the guide port 86. A support sleeve 87 is slidably sleeved on the outside of the turntable 83. The lower end of the support sleeve 87 is fixedly connected to a bracket 88. The bracket 88 is fixedly connected to the tank body 1. By designing the bracket 88, the support sleeve 87 can be supported. By designing the feeding mechanism 8, different materials can be added and mixed.

[0024] Please see Figure 1 , Figure 2 , Figure 4The weighing mechanism 9 includes a storage tray 91, inside which a weighing scale 92 is installed. A rotary motor 94 is fixedly installed at the right end of the feed inlet 4. The output end of the rotary motor 94 is rotatably connected to the feed inlet 4. A rotating block 93 is fixedly connected to the left end of the output end of the rotary motor 94. The rotating block 93 is rotatably connected to the feed inlet 4 via a bearing.

[0025] The specific implementation process of this utility model is as follows: During use, the solenoid valve on the bottom guide port 86 of the material cylinder 84 is opened, and the material is discharged through the material cylinder 84. The material enters the inside of the inlet 4 and falls into the weighing scale 92 inside the storage tray 91. The weighing scale 92 weighs the raw material. When the preset weight is reached, the solenoid valve on the guide port 86 closes. Subsequently, the output end of the rotating motor 94 drives the rotating block 93 and the storage tray 91 to rotate and flip. At this time, the weighed material is conveyed into the tank 1 through the inlet 4. During the material conveying process, the rotating motor 96... The connecting rod 97 and the elastic block 98 will rotate. The elastic block 98 can collide with the flipped storage tray 91, which can make the storage tray 91 vibrate, avoiding material residue inside the storage tray 91 and causing waste. This can achieve accurate metering and addition of raw materials. After the material enters the tank 1, the output end of the drive motor 5 can drive the rotating rod 7 to rotate. The rotating rod 7 drives the stirring rod 10 to rotate, which can stir and mix the material. At the same time, the rotating rod 7 will also drive the scraper 11 to rotate along the inner wall of the tank 1, which can scrape off the material attached to the inner wall of the tank 1 and avoid waste.

[0026] When different materials need to be added and mixed, the self-locking motor 81 is started. The output end of the self-locking motor 81 drives the rotating shaft 82 to rotate. The rotating shaft 82 drives the turntable 83 to rotate. The turntable 83 slides along the support sleeve 87. At the same time, the turntable 83 drives the material cylinder 84 to rotate. The material cylinder 84 in another position can be rotated to the top of the feed port 4, so that different materials can be added and mixed. This can realize the automatic addition of raw materials and make it more convenient to use.
