[0030] Embodiment 1: In order to solve the problem of uneven mixing of raw materials in the prior art, the following solution is disclosed. For details, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, it includes a mixing barrel 1, a support frame 3, a discharge port 4, a support base 5, and a feed port 11. The top of the mixing barrel 1 is provided with a feed port 11, and the bottom of the mixing barrel 1 is provided with a discharge port 4. Support frames 3 are provided on both sides of the bottom of the mixing barrel 1, and both sides of the bottom of the support frame 3 are welded to the support base 5. An adjusting mechanism 6 is provided inside the support frame 3. The adjusting mechanism 6 includes an adjusting motor 606, and the adjusting motor 606 is arranged inside the support frame 3. One side of the adjusting motor 606 is rotatably connected to a driving shaft 603, and the outer side of the driving shaft 603 is sleeved with a connecting bevel gear 605, and one side of the connecting bevel gear 605 is meshed with a linkage bevel gear 607, and a linkage shaft 608 is penetrated inside the linkage bevel gear 607, and the linkage shaft 608 is An adjusting gear 609 is sleeved on the outer side of 8, and an adjusting tooth 610 is meshed on one side of the adjusting gear 609, and the adjusting tooth 610 is fixed to the outer side of the mixing barrel 1, and a driving bevel gear 602 is sleeved on the outer side of the driving shaft 603 on one side of the connecting bevel gear 605, and a driven bevel gear 601 is meshed on one side of the driving shaft 603, and a stirring shaft 604 is penetrated inside the driven bevel gear 601, and one end of the stirring shaft 604 extends to the inside of the mixing barrel 1, the driving bevel gear 602 and the connecting bevel gear 605 have the same size and shape, and the driving bevel gear 602 and the connecting bevel gear 605 have the same movement direction, and a plurality of adjusting teeth 610 are provided, and the cross-sections of the plurality of adjusting teeth 610 are all trapezoidal, and the plurality of adjusting teeth 610 are distributed in a ring shape.

[0031] In the present embodiment, when in use, the regulating motor 606 is started to drive the driving shaft 603 to rotate, and the driving shaft 603 drives the driving bevel gear 602 to rotate synchronously while the driving bevel gear 602 and the driven bevel gear 601 are meshed with each other, so the driving bevel gear 602 rotates while driving the driven bevel gear 601 to rotate synchronously, thereby driving the stirring shaft 604 to rotate, and then driving the cross bar 9 to rotate, and the cross bar 9 rotates while driving the scraper 2 to rotate, so that the raw materials adhered to the inner wall of the mixing barrel 1 can be scraped to reduce the waste of resources, and the cross bar 9 rotates while driving the stirring rod 7 and the fixed rod 8 to rotate synchronously, thereby stirring the raw materials inside the mixing barrel 1 and mixing them evenly.
