[0026] Reference Figure 3 - Figure 4The mixing mechanism 5 includes a chute 51, which is located on the inner front wall of the support 42. A discharge port 52 is located on the inner bottom wall of the chute 51. A pre-set groove 53 is located on the inner top wall of the cover plate 44. The medicine is pre-added through the pre-set groove 53 to ensure the correct mixing ratio. A scale 54 is fixedly connected to the inner front wall of the cover plate 44 to accurately observe the dosage of medicine added to the pre-set groove 53. A ramp 55 is fixedly connected to the inner bottom wall of the chute 51. A movable plate 56 is fixedly connected to the rear outer wall of the cover plate 44. A discharge port 57 is opened on the bottom inner wall of the movable plate 56. A discharge port 52 penetrates the bottom outer wall of the bracket 42.

[0027] Working principle: By pulling the handle on the cover plate 44, the cover plate 44 is pulled out of the annular opening 43. Then, the medicine is added into the pre-set tank 53. The dosage is then adjusted by the through scale 54. After the dosage is controlled, the cover plate 44 is pushed into the annular opening 43 and leveled. The movement of the cover plate 44 moves the movable plate 56, which then inserts into the slide chute 51, aligning the discharge port 52 with the outlet 57. This allows the medicine in the pre-set tank 53 to flow into the discharge port 52 along the slope 55. The medicine is then discharged. The medicine flows out of the outlet 57 through the inlet 52, and then falls into the mixing tank 41. Then, the frame 1 is turned on to make the drive wheel 3 rotate. The rotation of the drive wheel 3 drives the mixing tank 41 to rotate. The rotation of the mixing tank 41 causes the medicine inside to tumble and shake. At the same time, when the medicine tumbles, it comes into contact with the mixing blade 46, so that the mixing blade 46 and the diversion port 47 cooperate to stir and divert the medicine, so that the medicine is evenly mixed when it tumbles and stirs. At the same time, when the mixing tank 41 rotates, it comes into contact with the scraper plate 48, so that the scraper plate 48 scrapes off the medicine adhering to the mixing tank 41 in real time.
