A first feed pipe 5, a first discharge pipe 6, a second feed pipe 7, and a second discharge pipe 8 are fixedly installed on the corresponding side surfaces of the device body 1, respectively. The second feed pipe 7 and the second discharge pipe 8 are located below the first feed pipe 5 and the first discharge pipe 6. A first sealed cabin 3 is arranged between the end surface of the piston 2 and the device body 1, and a second sealed cabin 4 is arranged between the bottom surface of the piston 2 and the device body 1. The first sealed cabin 3 and the second sealed cabin 4 are fixedly installed on the corresponding side surfaces of the device body 1. The inner wall of the sealed cabin 4 is provided with a first sealing groove 9, and the first sealing groove 9 is movably connected with a first sealing plate 11. The inner walls of the first sealed cabin 3 and the second sealed cabin 4 are provided with a second sealing groove 12, and the second sealing groove 12 is movably connected with a second sealing plate 14. The piston 2 reciprocates in the device body 1, so that the pressure inside the first sealed cabin 3 and the second sealed cabin 4 changes. At this time, the medicines in the first sealed cabin 3 and the second sealed cabin 4 are regularly opened and closed through the first feed pipe 5 and the first discharge pipe 6 and the second feed pipe 7 and the second discharge pipe 8, so that the device body 1 can regularly and continuously load and discharge materials, thereby improving the loading rate of animal medicines.

[0028] The first feed pipe 5 and the first discharge pipe 6 are in communication with the first sealed cabin 3 , and the second feed pipe 7 and the second discharge pipe 8 are in communication with the second sealed cabin 4 .

[0029] The positions of the two first sealing grooves 9 correspond to the first feed pipe 5 and the second feed pipe 7 respectively, and the positions of the second sealing grooves 12 correspond to the first discharge pipe 6 and the second discharge pipe 8 respectively.

[0030] A movable rod 15 is fixedly installed on the end surface of the piston 2, one end of the movable rod 15 extends to the outside of the device body 1, and an electric telescopic rod is arranged on the outside of the device body 1. The electric telescopic rod is a conventional electric-controlled push rod in the prior art. The telescopic end of the electric telescopic rod is fixedly connected to one end of the movable rod 15, and the electric telescopic rod provides power for the movement of the piston 2.

[0031] A first spring shaft 10 is provided on the inner wall of the first sealing groove 9, and the first sealing plate 11 is movably connected to the first sealing groove 9 through the first spring shaft 10. A second spring shaft 13 is provided on the inner wall of the second sealing groove 12, and the second sealing plate 14 is movably connected to the second sealing groove 12 through the second spring shaft 13. The first spring shaft 10 and the second spring shaft 13 are conventional elastic reset shafts in the prior art. The cooperation of the first spring shaft 10 and the second spring shaft 13 ensures that the first sealing plate 11 and the second sealing plate 14 are opened and closed regularly.

[0032] The utility model uses the following steps: when the animal medicine vacuum feeding device is in use, when the animal medicine is fed, the electric telescopic rod is extended to carry the piston 2 to move downward, and the piston 2 moves toward the second sealed cabin 4. At this time, the second sealed cabin 4 is compressed and the pressure increases. The pressure of the second sealed cabin 4 is higher than the external air pressure. At this time, the first sealing plate 11 corresponding to the second feeding pipe 7 rotates under the action of the first spring shaft 10, and then seals with the first sealing groove 9. At this time, the second feeding pipe 7 is closed, and the second sealed cabin 4 is compressed and the pressure increases. At this time, the second sealing plate 14 corresponding to the second discharge pipe 8 rotates under the action of the pressure force and separates from the second sealing groove 12. At this time, the animal medicine inside the second sealed cabin 4 is discharged from the second discharge pipe 8. Since the piston 2 moves toward the second sealed cabin 4, the pressure inside the first sealed cabin 3 decreases. At this time, the external air pressure is greater than the internal pressure of the first sealed cabin 3. At this time, the first Under the action of pressure, the first sealing plate 11 corresponding to the feed pipe 5 rotates on the surface of the first spring shaft 10, so that the first sealing plate 11 is separated from the first sealing groove 9. At this time, the second sealing plate 14 is sealed with the second sealing groove 12 by external pressure. At this time, the animal medicine enters the first sealed cabin 3 through the first feed pipe 5. When the electric telescopic rod is recovered and the piston 2 moves toward the first sealed cabin 3, the animal medicine inside the first sealed cabin 3 is discharged from the first discharge pipe 6. This scheme causes the pressure inside the first sealed cabin 3 and the second sealed cabin 4 to change through the reciprocating motion of the piston 2 in the device body 1. At this time, the medicine in the first sealed cabin 3 and the second sealed cabin 4 is regularly opened and closed through the first feed pipe 5 and the first discharge pipe 6 and the second feed pipe 7 and the second discharge pipe 8, so that the device body 1 can be regularly and continuously loaded and discharged, thereby improving the loading rate of the animal medicine.

The first limit block 16 and the second limit block 17 are set to limit the rotation angle of the first sealing plate 11 and the second sealing plate 14, and then through the cooperation of the first spring shaft 10 and the second spring shaft 13, the regular opening and closing of the first sealing plate 11 and the second sealing plate 14 are guaranteed, thereby ensuring that the device body 1 can have regular and continuous loading and discharging.

[0035] The utility model uses steps: when the animal medicine vacuum feeding device is in use, during the regular opening and closing process of the first feed pipe 5 and the first discharge pipe 6 and the second feed pipe 7 and the second discharge pipe 8, in order to prevent the first sealing plate 11 and the second sealing plate 14 from rotating too much, which may cause abnormal opening and closing of the first sealing plate 11 and the second sealing plate 14, a first limit block 16 and a second limit block 17 are provided to limit the rotation angle of the first sealing plate 11 and the second sealing plate 14, and then the first spring shaft 10 and the second spring shaft 13 cooperate to ensure the regular opening and closing of the first sealing plate 11 and the second sealing plate 14, thereby ensuring that the device body 1 can load and discharge materials regularly and continuously.
