[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Reference Figures 1-5 A high-efficiency sieving machine for veterinary drug raw materials includes a feeding section 101 and a sieving tank 2 mounted on a support 1. A feed pipe 201 is fixedly connected to the sieving tank 2. The feeding section 101 is connected to the feed pipe 201. The machine also includes:

[0029] Grinding plate 204 is fixedly connected in screening tank 2;

[0030] The feed pipe 201 is positioned above the grinding plate 204;

[0031] Drive rod 6 is rotatably connected to screening tank 2;

[0032] Connecting rod 601 is fixedly connected to drive rod 6;

[0033] The grinding roller 8 is rotatably connected to the end of the connecting rod 601 away from the drive rod 6, and the grinding roller 8 is positioned directly above the grinding plate 204;

[0034] The discharge pipe 203 is fixedly connected to the bottom of the screening tank 2.

[0035] The screening tank 2 is fixedly connected to a sieve plate 205, which is located directly below the grinding plate 204. A recovery pipe 202 is fixedly connected to the side wall of the screening tank 2, and the top of the recovery pipe 202 is connected to the screening tank 2. A connecting pipe 206 is also fixedly connected to the side wall of the screening tank 2, and the connecting pipe 206 is connected to the recovery pipe 202.

[0036] An air pump 4 is fixedly connected to the bracket 1, and an air blowing pipe 401 is fixedly connected to the air outlet end of the air pump 4. The air blowing pipe 401 is connected to the recovery pipe 202.

[0037] Reference Figure 2 , Figure 3 A drive motor 5 is fixedly connected to the top of the screening tank 2, and the drive end of the drive motor 5 is fixedly connected to the drive rod 6.

[0038] Reference Figures 1-5 During use, the feeding unit 101 feeds the processed veterinary medicine material into the screening tank 2. At this time, the drive motor 5 is started, which drives the drive rod 6 to rotate. The rotation of the drive rod 6 will drive the connecting rod 601 and the grinding roller 8 connected to it to rotate. At this time, the grinding roller 8 will squeeze and knead the veterinary medicine material on the grinding plate 204. After being ground, the veterinary medicine material will fall through the leakage hole at the bottom of the grinding plate 204. The fallen material will be screened by the screening action of the screen plate 205. The fully ground material will fall through the screen plate 205 to the bottom of the screening tank 2. The insufficiently ground material will fall through the connecting pipe 206 into the recovery pipe 202 under the guiding action of the inclined screen plate 205. At this time, the air pump 4 is started. The air pump 4 intermittently sprays air to blow the material in the recovery pipe 202, and then blows the insufficiently ground material back into the screening tank 2 for further grinding.

[0039] It should be noted that air pump 4 is a commercially available high-pressure pump.

[0040] It also includes a liquid nitrogen section 3, on which a conveying pipe 301 is fixedly connected. The conveying pipe 301 is connected to the recovery pipe 202, and the gas outlet end of the conveying pipe 301 faces the material outlet end of the recovery pipe 202.

[0041] In practice, when the recovery pipe 202 is conveying insufficiently ground veterinary drug material into the screening tank 2, liquid nitrogen can be sprayed into the recovery pipe 202 through the liquid nitrogen section 3 equipped with a liquid nitrogen pump. At this time, the liquid nitrogen injected through the conveying pipe 301 will come into contact with the veterinary drug material being conveyed in the recovery pipe 202. On the one hand, it can effectively push the veterinary drug material in the conveying process into the screening tank 2. On the other hand, the liquid nitrogen will come into contact with the veterinary drug material. At this time, the veterinary drug material will become brittle due to the low temperature of the liquid nitrogen, which will facilitate subsequent grinding on the grinding plate 204.

[0042] It should be noted that the discharge end of the liquid nitrogen pump is connected to the delivery pipe 301.

[0043] Reference Figure 4 A filter screen 4011 is fixedly connected to the air blowing pipe 401.

[0044] The filter screen 4011 installed on the air blowing pipe 401 can effectively prevent veterinary medicine from falling into the air pump 4.

[0045] Reference Figure 3 , Figure 5 In actual operation, a rotating rod 7 is fixedly connected to the bottom of the drive rod 6, and a paddle 701 is fixedly connected to the rotating rod 7.

[0046] The rotation of the drive rod 6 will synchronously drive the rotation rod 7 at its bottom to rotate. The rotation of the rotation rod 7 will drive the bottom paddle 701 to rotate. When the paddle 701 rotates, it can push the ground material off on one hand, and on the other hand, it can push the unground material at the bottom of the grinding plate 204. It can effectively push the material into the gap between the grinding roller 8 and the grinding plate 204, thereby improving the grinding efficiency.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
