[0048] The filter assembly 4 is arranged inside the mixing barrel 1. The filter assembly 4 includes a filter plate 41, a block 42, a fixed block 43, a damping rod 44 and a fixed ball 45. The filter plate 41 is movably connected to the inner wall of the mixing barrel 1. The two sides of the bottom end of the filter plate 41 are fixedly connected with the block 42. The two sides of the inner wall of the mixing barrel 1 are fixedly connected with two fixed blocks 43. The opposite sides of the front and rear fixed blocks 43 are provided with guide holes. The inner wall of the guide hole is fixedly connected with a damping rod 44. A spring is sleeved on the damping rod 44. The end of the damping rod 44 close to the block 42 is fixedly connected with a fixed ball 45, the front and rear ends of the spring are fixedly connected to the damping rod 44 and the fixing ball 45 respectively. By bringing the filter plate 41 close to and tightly against the upper side of the fixing block 43, the clamping block 42 is inserted between the two fixing balls 45. Under the action of the damping rod 44 and the spring, the fixing ball 45 will generate a thrust on the clamping block 42 to fix it to the filter plate 41, thereby filtering the mixed raw materials and preventing impurities from affecting subsequent processing. After processing, the filter plate 41 can be removed by lifting it upwards, which is convenient for cleaning impurities remaining on its upper side and ensuring the subsequent filtering effect.

[0049] The stirring assembly 9 is used in conjunction with the protective shell 8 and is arranged inside the mixing barrel 1.

A plurality of stirring plates 95 are fixedly connected to the lower end of the side wall of the shaft rod 91. By starting the motor 93, the driving bevel gear 94 can be driven to rotate, so that the upper driven bevel gear 92 starts to drive the shaft rod 91 and the stirring plates 95 to rotate, and the raw materials in the mixing barrel 1 are fully stirred and mixed. The cooperation of multiple inclined stirring plates 95 can reduce the time required for mixing.

[0050] Embodiment 2:

[0051] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0052] A sleeve 96 used in conjunction with the cover plate 5 is sleeved on the shaft rod 91. The inner wall of the sleeve 96 is rotatably connected to the side wall of the shaft rod 91 by being provided with a sealed bearing. The outer wall of the sleeve 96 penetrates the cover plate 5 and is rotatably connected thereto by being provided with a sealed bearing. The driven bevel gear 92 on the lower side is fixedly connected to the outer upper side of the sleeve 96.
