[0031] Furthermore, the lower end of the stirring cylinder body 1 is arranged in a V-shaped structure, and the stirring blades 53 at the lower end of the stirring rod 52 are arranged in a variable-diameter spiral structure, so that the discharging is complete.

[0032] The usage method of this embodiment is as follows: Close the second valve on the connecting pipe 62, open the first valve on the exhaust pipe 63, and start the exhaust fan 61. Under the action of the exhaust fan 61, the air in the stirring cylinder body 1 passes through the filter net 7 and then enters the exhaust hood 6, and then is discharged through the exhaust pipe 63, making the inside of the stirring cylinder body 1 in a negative pressure state during the feeding process. Wait for the materials to be premixed and stirred to be added into the inside of the stirring cylinder body 1 through the feed hopper 2 and the feed port 21. After the feeding is completed, close the feed port 21, close the first valve on the exhaust pipe 63, open the second valve on the connecting pipe 62, and the servo motor 5 drives the connecting rod 51 and the stirring rod 52 to rotate.

When heating is required during stirring, power on the heater 64, and the heater 64 heats the circulating air, thus having the function of heating and drying. After stirring evenly, open the discharge port 3, and the materials are discharged from the discharge port 3, realizing the premixing and stirring operation of veterinary medicine powder and premix. The combination of stirring and agitation makes the stirring efficient, uniform, and highly functional. The feeding and exhausting of the stirring cylinder body 1 form a negative pressure to prevent dust from rising during feeding, and the filter net 7 prevents the medicine powder from overflowing during exhausting. The cleaning plate 71 and the brush 72 on the connecting rod 51 rotate synchronously in the stirring cylinder body 1 during the stirring process, and the brush 72 cleans the filtering surface of the filter net 7, making the cleaning of the filter net 7 convenient and the exhausting smooth.

[0033] Embodiment 2

[0034] The structure of the premixing and stirring equipment for veterinary medicine powder and premix in this embodiment is basically the same as that of the premixing and stirring equipment for veterinary medicine powder and premix in Embodiment 1. The difference lies in that the discharging mechanism 4 includes a plugging plate 41, a corner cylinder 42, and a plugging table 43 (see Figures 1 to 5).
