[0056] The implementation principle of a homogenizer for veterinary drug mixing in an embodiment of the present application is as follows: a variety of veterinary drugs are put into the mixing barrel 2 through different feed pipes 24, and the first power unit 4 drives the stirring blade 22 to rotate. During the rotation of the stirring blade 22, the various drug liquids are stirred and mixed. After the mixing is completed, the driving component 6 drives the valve 3 to open, and at the same time, the first moving component 5 drives the pushing plate 23 to move downward. During the movement of the pushing plate 23, the pushing plate 23 pushes the drug liquid to move downward, so that the drug liquid can quickly enter the body 1 through the connecting pipe 21, and the body 1 homogenizes the drug liquid. The homogenized drug liquid is moved out of the body 1 from the discharge port 12, completing the homogenization of the various veterinary drugs. There is no need for the staff to carry the drug liquid back and forth, which saves time and improves the work efficiency of veterinary drug homogenization.
