Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a high-efficiency screening device for producing veterinary drugs. Background Art
[0002] In the daily feeding process of livestock, in order to prevent the occurrence of nutritional deficiencies in livestock, specific vitamins and minerals (such as taurine, etc.) are generally supplemented regularly to enhance the immunity of animals. However, the content of vitamins and minerals in food is low, so it is difficult to supplement. Therefore, breeders generally add specific veterinary drugs to feed to supplement specific vitamins and minerals for livestock. The production process of veterinary drugs includes: raw material procurement and inspection, raw material pretreatment, preparation and mixing, granulation, drying, screening and packaging. The screening step is to use a vibrating screen to remove veterinary drugs with unqualified particles (such as large particles or small particles), so that the veterinary drugs have uniform particles, thereby improving the stability and consistency of veterinary drugs.
[0003] As in the prior art, the patent with the patent authorization announcement number CN214865165U discloses a high-efficiency screening device for veterinary drug production. The high-efficiency screening device for veterinary drug production sets the trough body on the spring in an inclined state. When the vibration motor at the bottom of the trough body works, it can drive the trough body to form regular shaking, thereby screening the internal materials. In the structure of the trough body, a discharge port is opened at its front end so that the fine materials that fall through the sieve can be discharged one after another, thereby achieving the purpose of continuous unloading; the screen is carried on the boss on the inner wall of the trough body and is tightened and fixed by bolts. This fixing mode makes the loading and unloading of the screen more convenient and quick; the high-efficiency screening device for veterinary drug production sets the end cover above the trough body in a non-contact state, and uses the induced draft fan to form a negative pressure above the trough body, so that the flying powder in the screening process is collected, alleviating the pollution problem in the workshop. This high-efficiency screening device for veterinary drug production significantly improves the functional characteristics of the screening device and has a good use effect.
[0004] Although the screening device in the above patent collects the flying powder during the screening process and alleviates the pollution problem in the workshop, it still has certain defects:
[0005] When the size of veterinary drug particles is very close to the size of the sieve holes of the vibrating screening machine, these particles are easily stuck in the sieve holes, forming the so-called "critical hole blockage". In this case, the particles are difficult to pass through the sieve holes during the vibration process, but will be stuck, causing the sieve holes to be blocked. If they are not cleaned for a long time, the efficiency of the entire screening process will be affected. The commonly used cleaning method is to use a brush to repeatedly clean or use a tool to knock on the sieve to clean the sieve, so as to facilitate subsequent screening work. However, due to the large area of the sieve, it takes a long time to clean, so this cleaning method is more inconvenient. Summary of the invention
[0006] In view of the deficiencies of the prior art, the utility model provides a high-efficiency screening device for producing veterinary drugs to solve the problems raised by the background technology and make the cleaning of the first sieve plate and the second sieve plate simpler and more convenient.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an efficient screening device for producing veterinary drugs, comprising a vibrating screening machine body, a frame installed in the middle position of the vibrating screening machine body, a partition fixedly connected to the middle position of the frame, a first sieve plate rotatably connected to the frame is provided on one side of the partition, a second sieve plate rotatably connected to the frame is provided on the other side of the partition, and a transmission assembly is provided at one end of the frame.
[0008] Furthermore, the transmission assembly includes a driven gear, a transmission gear, a rotating shaft and a transmission belt. The driven gear is fixedly connected to the end of the first sieve plate, the transmission gear is rotationally connected to the frame, the transmission gear is meshed with the driven gear, the rotating shaft is fixedly connected to the end of the second sieve plate, and a transmission belt is provided on the outside of the rotating shaft and the transmission gear.
[0009] Furthermore, an elastic buffer block is fixedly connected to the top of the partition.
[0010] Furthermore, the end of the elastic buffer block is configured in a conical shape.
[0011] Furthermore, a hand wheel is fixedly connected to one end of the rotating shaft away from the second screen plate.
[0012] Furthermore, a sleeve is sleeved on the outside of the rotating shaft, the sleeve is fixedly connected to the vibration screening machine body, one side of the sleeve is threadedly connected with a fixing bolt, and the fixing bolt passes through the sleeve and abuts against the rotating shaft.
[0013] Furthermore, both sides of the first sieve plate and the second sieve plate are inclined.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] This high-efficiency screening device for producing veterinary drugs can stop the vibration screening machine body when a large number of veterinary drug particles are stuck on the first sieve plate and the second sieve plate, and then rotate the first sieve plate and the second sieve plate to make the first sieve plate and the second sieve plate collide with the partition plate. During the collision, the veterinary drug particles will be vibrated and will automatically separate from the first sieve plate and the second sieve plate. This cleaning method is simple, convenient and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] See also Figure 1-5 A high-efficiency screening device for producing veterinary drugs includes a vibrating screening machine body 1, a frame 2 is installed in the middle position of the vibrating screening machine body 1, a partition 3 is fixed in the middle position of the frame 2, a first sieve plate 5 rotatably connected to the frame 2 is provided on one side of the partition 3, a second sieve plate 6 rotatably connected to the frame 2 is provided on the other side of the partition 3, and a transmission assembly is provided at one end of the frame 2.
[0024] The high-efficiency screening device for producing veterinary drugs in the utility model can stop the vibration screening machine body 1 when more veterinary drug particles are stuck on the first sieve plate 5 and the second sieve plate 6, and then rotate the first sieve plate 5 and the second sieve plate 6 to make the first sieve plate 5 and the second sieve plate 6 collide with the partition 3. During the collision, the veterinary drug particles will be vibrated and will automatically separate from the first sieve plate 5 and the second sieve plate 6. This cleaning method is simple, convenient and easy to operate. In addition, the structure of the vibration screening machine body 1 in the utility model is similar to the prior art, and the patent with patent authorization announcement number CN214865165U discloses a high-efficiency screening device for veterinary drug production, so it will not be elaborated on here.
[0025] like Figure 3 and Figure 5As shown, the transmission assembly includes a driven gear 7, a transmission gear 8, a rotating shaft 9 and a transmission belt 10. The driven gear 7 is fixedly connected to the end of the first sieve plate 5, the transmission gear 8 is rotationally connected to the frame 2, the transmission gear 8 is meshed with the driven gear 7, the rotating shaft 9 is fixedly connected to the end of the second sieve plate 6, and the rotating shaft 9 and the transmission gear 8 are externally sleeved with a transmission belt 10.
[0026] Specifically, when it is necessary to rotate the first sieve plate 5 and the second sieve plate 6, you only need to rotate the rotating shaft 9 first. The rotating shaft 9 will drive the transmission gear 8 to rotate through the transmission belt 10, and the transmission gear 8 will drive the driven gear 7 meshing therewith to rotate. The driven gear 7 will drive the first sieve plate 5 to rotate, and the rotating shaft 9 will drive the second sieve plate 6 to rotate. In this way, the first sieve plate 5 and the second sieve plate 6 can be flipped toward the direction of the partition plate 3 at the same time until they collide with the partition plate 3, so that the veterinary drug particles are vibrated and separated from the first sieve plate 5 and the second sieve plate 6.
[0027] like Figure 3 and Figure 4 As shown, an elastic buffer block 4 is fixedly connected to the top of the partition plate 3. After being hit by the first sieve plate 5 and the second sieve plate 6, the elastic buffer block 4 absorbs the impact force of the partition plate 3 to prevent the partition plate 3 from being damaged.
[0028] like Figure 3 and Figure 4 As shown, the end of the elastic buffer block 4 is set in a conical shape. The elastic buffer block 4 with a conical shape has a larger contact area with the first sieve plate 5 and the second sieve plate 6, and has a better effect of absorbing impact force.
[0029] like Figure 1 and Figure 3 As shown, a hand wheel 11 is fixedly connected to one end of the rotating shaft 9 away from the second sieve plate 6. Rotating the second sieve plate 6 by the hand wheel 11 is more labor-saving and convenient.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a sleeve 13 is sleeved on the outside of the rotating shaft 9 , and the sleeve 13 is fixedly connected to the vibration screening machine body 1 . A fixing bolt 12 is threadedly connected to one side of the sleeve 13 , and the fixing bolt 12 passes through the sleeve 13 and abuts against the rotating shaft 9 .
[0031] Specifically, when the first sieve plate 5 and the second sieve plate 6 need to be fixed in a horizontal state, the fixing bolts 12 can be tightened so that the fixing bolts 12 abut against the rotating shaft 9, thereby preventing the first sieve plate 5 and the second sieve plate 6 from rotating by themselves.
[0032] like Figure 4 and Figure 5As shown, both sides of the first sieve plate 5 and the second sieve plate 6 are inclined. The inclined first sieve plate 5 and the second sieve plate 6 rotate more smoothly.
[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
