[0022] The utility model is further described below in conjunction with embodiments.

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 4 The mixing assembly 3 includes a ring 31 arranged on the inner wall of the mixing barrel 1, a connecting block 32 fixedly installed on the inner side of the ring 31, and a placing frame 33 fixedly installed on one side of the connecting block 32. A filter screen 34 is arranged at the bottom of the placing frame 33. A spiral rotating rod 35 is rotatably connected inside the placing frame 33. The outer surface of the spiral rotating rod 35 contacts the inner wall of the placing frame 33. A motor A36 is arranged on the upper surface of the mixing barrel 1. A connecting ring 37 is arranged on the output end of the motor A36 and the outer surface of the spiral rotating rod 35. The outer surfaces of the two groups of connecting rings 37 are sleeved with belts 38. Some raw materials that are difficult to mix are first placed in the placing frame 33, and the motor A is started from 36 to drive one group of connecting rings 37 to rotate, and the other group of connecting rings 37 is driven to rotate through the belt 38. Therefore, the spiral rotating rod 35 rotates, so that the spiral rotating rod 35 can crush the raw materials in the placing frame 33. The processed raw materials are transferred into the mixing barrel 1 from the filter screen 34 at the bottom of the placing frame 33, so that it is easier to mix with the solution in the mixing barrel 1, thereby improving the mixing effect.
