Description

Technical Field

[0001] This invention relates to the field of livestock medicine administering equipment, specifically to a livestock medicine administering equipment and its usage method. Background Technology

[0002] In livestock farming, the health of livestock directly affects the efficiency of farming and the quality and safety of livestock products. Livestock are susceptible to various diseases, some of which may affect their reproductive system. Administering medication orally ensures that the drug reaches the reproductive organs precisely, increasing the drug concentration at the lesion site, thereby more effectively killing pathogens, eliminating inflammation, and promoting the recovery of the reproductive organs.

[0003] Chinese Patent (Announcement No.: CN116350381A) addresses the problem of difficulty in administering medication to livestock. Operators often struggle to open the livestock's mouths, making the process challenging. Forcibly opening the mouth with instruments can cause stress and harm to the operator, further complicating the process by making it difficult to maintain the livestock's head position during medication administration. This new medication feeding device induces the livestock to open its mouth, then gradually expands to secure the head, preventing stress. It also effectively directs the medication from the cartridge into the feeding tube, avoiding the problem of residual medication at the bottom of the cartridge being difficult to drain.

[0004] In livestock farming, existing livestock medication administration devices have certain limitations in treating reproductive system diseases. While these devices can administer medication through the esophagus while keeping the animal's head still, they are ineffective when administering medication to the reproductive system. The animal's body is difficult to stabilize, leading to significant struggle due to fear or discomfort, and potentially resulting in the animal kicking the operator with its hind hooves. This not only poses a potential threat to the operator's safety but also severely hinders the smooth progress of the medication administration process, reducing treatment efficiency and accuracy. Therefore, this paper proposes a livestock medication administration device and its usage method. Summary of the Invention

[0005] The purpose of this invention is to provide a livestock medication applicator and its usage method, which has the advantage of ensuring smooth medication administration and solving the problem of livestock bodies being difficult to effectively fix.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a livestock medication applicator, comprising a fence frame and a top frame fixedly mounted thereon, a syringe for administering medication to the reproductive parts of livestock, and a water tank for receiving the medication, wherein the top frame is provided with a movement limiting mechanism for fixing the hindquarters of livestock and restricting the position of the hind legs. The limiting mechanism includes two sets of horizontal seats on the top frame. Each set of horizontal seats is provided with an inner clamp for holding the livestock. The top frame is provided with a translation component that drives the two sets of inner clamps to move synchronously towards or away from each other. The horizontal seat is equipped with a self-stopping component that restricts the horizontal movement of the livestock when the inner clamp is in close contact with the hindquarters of the livestock. A set of comb-shaped connecting frames is fixedly connected to both horizontal sides of the top frame. A notch-shaped locking post is fixedly connected to the end of the comb-shaped connecting frame away from the top frame. The notch-shaped locking post is equipped with a gathering component that limits the position of the livestock's hind legs. The horizontal seat is also equipped with a pressure delivery component that supplies liquid medicine into the syringe after the inner clamp stops moving horizontally.

[0007] Preferably, the translation component includes a bidirectional lead screw that rotates on a top support with a fixed axis. The bidirectional lead screw includes two sets of threaded portions integrally formed with opposite thread directions. Each of the two sets of threaded portions is threadedly connected to a set of inner cylinders. The two sets of transverse seats rotate on a set of inner cylinders with a fixed axis.

A return spring is provided in the inner groove, and the two ends of the return spring are fixedly connected to the horizontal seat and the positioning wedge, respectively. The inner shaft cylinder is provided with a wedge groove corresponding to the position of the positioning wedge. The top support is fixedly connected to a guide column, and both sets of horizontal seats are provided with slots for the guide column to slide through.

[0008] Preferably, the horizontal seat is provided with a side slide and a groove for sliding connection of the side slide. An end frame is fixedly connected to the side slide, and two sets of vertical guide rods slide through the end frame. Both sets of vertical guide rods are fixedly connected to the inner clamping plate. The end support is threaded with a locking bolt that limits the height of the vertical guide rod.

[0009] Preferably, the self-stopping component includes a positioning pin fixedly connected to the positioning wedge, and a V-shaped positioning groove is provided on the side slide for the positioning pin to slide. The positioning wedge is initially positioned in the wedge groove.

[0010] Preferably, the pressing assembly includes a hollow worm gear sleeved on a bidirectional lead screw and coaxially fixed with the inner shaft cylinder, the hollow worm gear being meshed with a worm wheel, and the worm wheel rotating on a horizontal seat with its axis fixed. A piston cylinder is fixedly connected to the horizontal seat, a pressure plate is fixedly connected to the inner circumferential surface of the piston cylinder, an inner extension rod is fixedly connected to the pressure plate, a connecting rod is rotatably connected to the inner extension rod, and the end of the connecting rod away from the inner extension rod is rotatably connected to the worm gear. The piston cylinder is fixedly connected to an inlet pipe and an outlet pipe. The inlet pipe is fixedly connected to the water tank, and the outlet pipe is fixedly connected to the syringe.

[0011] Preferably, the gathering component includes a forked open column that moves freely in the horizontal direction. The forked open column includes an integrally formed horizontal section, and the notch-type locking column has a column groove for sliding connection of the horizontal section. The comb-shaped connecting frame is equipped with a drive gear that is driven by a motor and rotates freely in the horizontal direction. The drive gear rotates on the comb-shaped connecting frame and is connected to the bidirectional lead screw. The drive gear is meshed with a central rack. The central rack passes through the notch and is fixedly connected to the horizontal part. At each of the horizontal ends of the central rack, there is a set of positioning components that limit its horizontal displacement.

[0012] Preferably, the positioning component includes lateral teeth disposed at the end of the central rack and meshing with the drive gear, and a rectangular groove is provided on the notch post for sliding connection between the central rack and the lateral teeth; An inward block and an outward block are fixedly connected to the same side of the central rack and the lateral teeth, respectively. A limit post is fixedly connected to the inward block. The limit post slides through the outward block and a relief spring is sleeved on its outer circumference. The two ends of the relief spring are fixedly connected to the inward block and the outward block, respectively.

[0013] Preferably, the forked open columns in the two sets of convergence components are staggered in the vertical direction.

[0014] A method for using a livestock medicine applicator, comprising the following steps: S1. Preparation: Before using the livestock medicine applicator, ensure that all parts of the equipment are in good condition and check that each part is securely installed. At the same time, prepare the required medicine solution and pour it into the water tank, ensuring that the medicine solution is sufficient and free of impurities. S2. Livestock guidance: Guide the livestock to be medicated to the fence frame, so that they stand with their backs to the top of the frame. During the guidance process, keep the movements gentle to avoid startling the livestock and ensure that they can enter the fence frame smoothly and be between the two sets of inner clamps to prepare for the subsequent fixing operation. S3. Body position restriction: The hind legs of livestock are restricted by the convergence component, so that the hind legs of livestock are restricted between the forked open columns, which effectively prevents the dangerous behavior of livestock kicking people with their hind legs due to discomfort during the administration of medicine. The translation component drives the inner clamp to fit tightly against the animal's spine, thereby fixing the animal's body and keeping it stable during the administration of medication. S4. Medication infusion: After restricting the position of the livestock, insert the syringe's outlet end into the livestock's reproductive position and complete the medication infusion process through the pressure delivery component. S5. Equipment Reset: After the medicine is injected, the inner clamp is driven to move to release the livestock. After the livestock are released, all parts automatically reset to their initial state, preparing for the next injection operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting a movement limiting mechanism, the present invention can effectively fix the animal's body, keeping it stable during the administration of medicine. This can prevent the animal from struggling excessively due to fear or discomfort, ensuring the smooth progress of the administration. Furthermore, it can be adaptively adjusted according to the different body sizes of the animals, achieving a close fit between the inner clamp and the animal's hindquarters, thus enhancing the reliability and adaptability of the fixation.

[0016] 2. By setting up a gathering component, this invention can effectively prevent livestock from kicking people during the medication process, thereby ensuring the personal safety of operators and also helping to reduce the self-injury that livestock may cause due to struggling.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 9 The present invention provides a technical solution: a livestock medicine administerer, including a fence frame and a top frame 1 fixedly installed on it, and also includes a syringe for administering medicine to the reproductive parts of livestock and a water tank for receiving the medicine liquid. The top frame 1 is provided with a movement limiting mechanism for fixing the hind back of the livestock and limiting the position of the hind legs. The limiting mechanism includes two sets of horizontal seats 4 set on the top frame 1. Each set of horizontal seats 4 is provided with a set of inner clamps 15 for supporting livestock. The top frame 1 is provided with a translation component that drives the two sets of inner clamps 15 to move synchronously towards or away from each other. The horizontal seat 4 is equipped with a self-stopping component that restricts the horizontal movement of the livestock when the inner clamp 15 is in close contact with the hind spine of the livestock. A set of comb-shaped connecting frames 2 are fixedly connected to both horizontal sides of the top frame 1. A notch-shaped locking post 22 is fixedly connected to the end of the comb-shaped connecting frame 2 away from the top frame 1. The notch-shaped locking post 22 is equipped with a gathering component that limits the position of the hind legs of the livestock. The horizontal seat 4 is also equipped with a pressure delivery component that supplies liquid medicine into the syringe after the inner clamping plate 15 stops moving horizontally.

[0021] like Figures 1-3As shown, when administering medication to the reproductive organs of livestock, the livestock is guided into the enclosure frame and its back is positioned between two sets of inner clamps 15. When securing the livestock, the translation component drives the two sets of inner clamps 15 to move synchronously towards each other in the horizontal direction, thereby causing both sets of inner clamps 15 to clamp and secure the livestock's hindquarters, effectively securing the livestock's body and keeping it stable during the medication administration process, thus ensuring the smooth progress of the medication administration operation.

[0022] At the same time, two sets of convergence components set below the top frame 1 limit the hind legs of the livestock, mainly restricting the hind limbs of the livestock, thereby effectively preventing the livestock from kicking people with their hind legs due to discomfort during the administration of medicine, so as to ensure the safety of the operators and help reduce the self-injury that the livestock may cause due to struggling.

[0023] After the inner clamp 15 secures the livestock, the horizontal position of the inner clamp 15 will no longer change under the drive of the self-stop component. At this time, the pressure delivery component will operate, which can drive the liquid medicine in the water tank to flow into the syringe. Therefore, after the inner clamp 15 stops moving, the liquid outlet of the syringe can be inserted into the reproductive part of the livestock, so that the liquid medicine can be gradually injected into the reproductive part under the drive of the pressure delivery component.

[0024] It should be noted that in actual use, in the initial state, the horizontal distance between the two sets of inner clamps 15 is at its maximum. When guiding livestock to move between the two sets of inner clamps 15, there may be differences in the distance between the livestock and the two sets of inner clamps 15. However, when the two sets of inner clamps 15 approach the livestock under the drive of the translation component, under the drive of the self-stop component, the inner clamps 15 can automatically stop moving after being pressed against the back of the livestock, so that both sets of inner clamps 15 can be pressed against the back of the livestock to achieve the purpose of restricting their bodies.

[0025] Therefore, in actual use, there is no need to deliberately adjust the position of the livestock between the two sets of inner clamps 15, and the two sets of inner clamps 15 will stop moving only after they are in close contact with the livestock under the drive of the self-stop component, thus adapting to different types and sizes of livestock and improving the versatility and adaptability of the medicine administerer.

[0026] In one preferred embodiment, the translation component includes a bidirectional lead screw 3 that rotates on a top support 1 with a fixed axis. The bidirectional lead screw 3 includes two sets of threaded parts that are integrally formed and have opposite thread directions. The two sets of threaded parts are threadedly connected to a set of inner cylinders 6, and the two sets of transverse seats 4 rotate on a set of inner cylinders 6 with a fixed axis. The horizontal seat 4 is provided with a positioning wedge 7 and an inner groove for sliding connection of the positioning wedge 7. A return spring 9 is provided in the inner groove, and the two ends of the return spring 9 are fixedly connected to the horizontal seat 4 and the positioning wedge 7 respectively. The inner shaft cylinder 6 is provided with a wedge groove 8 corresponding to the position of the positioning wedge 7. The top support 1 is fixedly connected to a guide column 5, and both sets of horizontal seats 4 are provided with slots for the guide column 5 to slide through.

[0027] The horizontal seat 4 is provided with a side slide 10 and has a groove for sliding connection of the side slide 10. An end support 13 is fixedly connected to the side slide 10, and two sets of vertical guide rods 14 slide through the end support 13. Both sets of vertical guide rods 14 are fixedly connected to the inner clamping plate 15. A locking bolt that limits the height of the vertical guide rods 14 is threaded on the end support 13.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, when the bidirectional lead screw 3 rotates freely in the vertical direction, since the positioning wedge 7 is initially in the wedge groove 8, the inner shaft cylinder 6 is restricted to rotate synchronously with the bidirectional lead screw 3 by means of the positioning wedge 7 being inserted into the wedge groove 8. The horizontal seat 4 is slidably mounted on the guide post 5, and the positioning wedge 7 is in the inner groove opened on the horizontal seat 4. Therefore, the horizontal seat 4 will not rotate due to the restriction of the guide post 5. Consequently, when the positioning wedge 7 is in the wedge groove 8, the inner shaft cylinder 6 will not rotate synchronously with the bidirectional lead screw 3.

[0029] Furthermore, when the bidirectional lead screw 3 rotates, it can drive the inner shaft cylinder 6, the horizontal seat 4, and the inner clamping plate 15 set on the horizontal seat 4 to move horizontally synchronously until the inner clamping plate 15 is in close contact with the hindquarters of the livestock. In actual use, the horizontal height of the vertical guide rod 14 and the inner clamping plate 15 below can be changed by tightening the locking bolt, so that the inner clamping plate 15 corresponds to the hindquarters of the livestock to be given medicine. Subsequently, by tightening the locking bolt, the height of the vertical guide rod 14 can be limited and the height of the vertical guide rod 14 can be prevented from changing under the action of external force. Therefore, in actual use, the height of the inner clamping plate 15 can be adjusted to adapt to different types of livestock, thereby improving the applicability of the medicine dispenser.

[0030] Based on the translation component embodiment, the self-stopping component includes a co-position pin 11 fixedly connected to the positioning wedge 7, and a V-shaped co-position groove 12 for the co-position pin 11 to slide on the side slide block 10. The positioning wedge 7 is initially located in the wedge groove 8.

[0031] like Figures 3-5As shown, when the inner clamping plate 15 is pressed against the back of the livestock, the inner clamping plate 15 is difficult to continue moving in the horizontal direction due to the obstruction of the livestock. At this time, the continuous rotation of the bidirectional screw 3 will still drive the horizontal seat 4 to continue moving in the horizontal direction through the inner shaft cylinder 6, thereby causing relative displacement between the side slide 10 and the horizontal seat 4.

[0032] At the same time, when the horizontal seat 4 and the side slide 10 are relatively displaced, that is, the side slide 10 can slide a certain distance on the horizontal seat 4, which in turn causes the corresponding pin 11 fixed on the positioning wedge 7 to slide on the V-shaped corresponding groove 12. The sliding process of the corresponding pin 11 in the V-shaped corresponding groove 12 will change the position of the positioning wedge 7 in the inner groove, so as to drive the return spring 9 to compress and deform and cause the positioning wedge 7 to disengage from the wedge groove 8.

[0033] In this process, after the positioning wedge 7 disengages from the wedge groove 8, as the bidirectional lead screw 3 continues to rotate, the inner shaft cylinder 6, which is threadedly engaged with it, will no longer be restricted by the positioning wedge 7. Consequently, the inner shaft cylinder 6 will rotate synchronously with the bidirectional lead screw 3. Therefore, the horizontal position of the horizontal seat 4 and the inner clamping plate 15 will not change.

[0034] It should be noted that after the medication is administered to the livestock, the bidirectional screw 3 is driven to rotate in the opposite direction, so that the positioning wedge 7 re-enters the wedge groove 8. Thus, during the continuous reverse rotation of the bidirectional screw 3, the transverse seat 4 and its inner clamping plate 15 can be driven away from the livestock, thereby completing the purpose of releasing the livestock and the resetting process.

[0035] Based on the self-stop component embodiment, the pressing component includes a hollow worm 16 sleeved on the bidirectional lead screw 3 and coaxially fixed with the inner shaft cylinder 6. The hollow worm 16 is meshed with a worm wheel 17, and the worm wheel 17 rotates on the horizontal seat 4 with a fixed axis. A piston cylinder 21 is fixedly connected to the horizontal seat 4. A pressure plate 20 is fixedly connected to the inner circumferential surface of the piston cylinder 21. An inner extension rod 19 is fixedly connected to the pressure plate 20. A connecting rod 18 is fixedly rotatable on the inner extension rod 19. One end of the connecting rod 18 away from the inner extension rod 19 is fixedly rotatable on the worm gear 17. The piston cylinder 21 is fixedly connected to an inlet pipe and an outlet pipe. The inlet pipe is fixedly connected to the water tank, and the outlet pipe is fixedly connected to the syringe.

[0036] like Figure 5 and Figure 6 As shown, after the positioning wedge 7 disengages from the wedge groove 8, the inner shaft cylinder 6 subsequently rotates synchronously with the bidirectional lead screw 3, and drives the hollow worm gear 16, which is fixed coaxially with it, to rotate synchronously. When the hollow worm gear 16 rotates, it can drive the worm wheel 17, which is meshed with it, to rotate in the horizontal direction.

[0037] Meanwhile, a freely swinging connecting rod 18 is provided between the worm gear 17 and the inner extension rod 19. When the worm gear 17 rotates continuously, the connecting rod 18 can drive the pressure plate 20, which is fixedly connected to the inner extension rod 19, to reciprocate within the piston cylinder 21. When the pressure plate 20 moves toward the connecting rod 18, it can draw the liquid medicine in the water tank through the liquid inlet pipe under negative pressure, so as to cause the liquid medicine in the water tank to enter the piston cylinder 21.

[0038] Furthermore, when the pressure plate 20 moves away from the connecting rod 18, it can squeeze the liquid medicine in the piston cylinder 21, so that the liquid medicine in the piston cylinder 21 flows to the syringe through the liquid outlet pipe, and is injected into the reproductive part of the livestock through the syringe. It should be noted that both the liquid inlet pipe and the liquid outlet pipe are equipped with one-way valves, and the valve ports of the two one-way valves are opposite to each other, thereby restricting the flow direction of the liquid medicine, so that the liquid medicine can only enter the piston cylinder 21 from the water tank and be discharged from the piston cylinder 21 to the liquid outlet of the syringe.

[0039] Based on the pressing and feeding assembly embodiment, the gathering assembly includes a fork-shaped open column 23 that moves freely in the horizontal direction. The fork-shaped open column 23 includes an integrally formed horizontal and vertical part 231, and the notch-locking column 22 is provided with a column groove for sliding connection of the horizontal and vertical part 231. The comb-shaped connecting frame 2 is equipped with a drive gear 24 that is driven by a motor and rotates freely in the horizontal direction. The drive gear 24 rotates on the comb-shaped connecting frame 2 and is connected to the bidirectional lead screw 3. The drive gear 24 is meshed with a central rack 25. The central rack 25 passes through the notch post 22 and is fixedly connected to the horizontal part 231. At the horizontal ends of the central rack 25, there is a set of positioning components that limit its horizontal displacement. The forked open posts 23 in the two sets of closing components are staggered in the vertical direction.

[0040] The positioning component includes a lateral tooth 26 disposed at the end of the central rack 25 and meshing with the drive gear 24, and a rectangular groove is provided on the notch post 22 for sliding connection between the central rack 25 and the lateral tooth 26. An inward block 27 and an outward block 28 are fixedly connected to the same side of the central rack 25 and the lateral teeth 26, respectively. A limiting post 29 is fixedly connected to the inward block 27. The limiting post 29 slides through the outward block 28 and a relief spring 30 is sleeved on its outer circumferential surface. The two ends of the relief spring 30 are fixedly connected to the inward block 27 and the outward block 28, respectively.

[0041] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the motor drives the drive gear 24 to rotate in the horizontal direction by fixing it on the comb-shaped connecting frame 2, and synchronously drives the bidirectional lead screw 3, which is connected to the drive gear 24, to rotate on the top frame 1. The bidirectional lead screw 3 and the drive gear 24 can achieve the transmission purpose through the meshing connection between multiple sets of bevel gears to ensure that the two can rotate synchronously.

[0042] At the same time, when the drive gear 24 rotates in the reverse direction, it can drive the bidirectional lead screw 3 to rotate to reduce the distance between the two sets of inner clamps 15 and achieve the purpose of restricting the position of the livestock. When the drive gear 24 rotates in the reverse direction, it can drive the transverse part 231 that meshes with it to move in the horizontal direction. The position of the hind legs of the livestock corresponds to the fork-shaped open post 23. The horizontal position of the fork-shaped open post 23 drives the hind legs of the livestock to enter between the fork-shaped open posts 23.

[0043] Meanwhile, the two sets of forked open columns 23 are at different heights. Therefore, when the two sets of forked open columns 23 move toward each other, the overlapping movement of the two sets of forked open columns 23 on the horizontal plane can limit the hind legs of the livestock to a greater extent, thereby limiting the activity space of the livestock, and simultaneously preventing the livestock from kicking people with their hind legs due to discomfort during the administration of medicine.

[0044] It should be noted that in actual use, the bidirectional lead screw 3 and the drive gear 24 rotate synchronously. The rotation process of the drive gear 24 changes the horizontal position of the fork-shaped open column 23. The horizontal movement stroke of the inner clamping plate 15 is limited by the size of the livestock and its initial position. Therefore, positioning components are provided at both ends of the central rack 25. When the drive gear 24 rotates continuously, the central rack 25 is at the end of its movement stroke. At this time, the drive gear 24 meshes with the side teeth 26 in a set of positioning components. The rotation process of the drive gear 24 will drive the side teeth 26 to reciprocate and jump on the central rack 25. The repeated jumping action of the side teeth 26 adapts to the rotation requirements of the drive gear 24, so as to avoid the rotation process of the drive gear 24 being interfered with.

[0045] Therefore, by setting the positioning component, when limiting the livestock, the hind legs of the livestock can be restricted first by the two sets of forked open columns 23, thereby ensuring that the inner clamp 15 can correspond to the position of the hind spine. Subsequently, as the drive gear 24 continues to rotate, the inner clamp 15 gradually approaches the position of the hind spine of the livestock and sticks tightly to it. After the two sets of inner clamps 15 have completed the limitation of the livestock, the pressing component can move automatically to complete the process of administering medicine to the reproductive part of the livestock.

[0046] A method for using a livestock medicine applicator, comprising the following steps: S1. Preparation: Before using the livestock medicine applicator, ensure that all parts of the equipment are in good condition and check that each part is securely installed. At the same time, prepare the required medicine solution and pour it into the water tank, ensuring that the medicine solution is sufficient and free of impurities. S2. Livestock guidance: Guide the livestock to be medicated to the fence frame and make them stand with their backs to the top frame 1. During the guidance process, keep the movements gentle to avoid startling the livestock and ensure that they can enter the fence frame smoothly and be between the two sets of inner clamps 15 to prepare for subsequent fixing operations. S3. Body position restriction: The hind legs of the livestock are restricted by the convergence component, so that the hind legs of the livestock are restricted between the forked open columns 23, which effectively prevents the livestock from kicking people with their hind legs due to discomfort during the administration of medicine. The inner clamp 15 is driven to fit tightly against the hindquarters of the livestock by the translation component, thereby fixing the livestock's body and keeping it stable during the administration of medicine. S4. Medication infusion: After restricting the position of the livestock, insert the syringe's outlet end into the livestock's reproductive position and complete the medication infusion process through the pressure delivery component. S5. Equipment Reset: After the medicine is injected, the inner clamp 15 is driven to move to release the livestock. After the livestock are released, all parts automatically reset to their initial state to prepare for the next injection operation.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

9. A method of using a livestock medicine applicator, applied to the livestock medicine applicator according to any one of claims 1-8, characterized in that: Includes the following steps: S1. Preparation: Before using the livestock medicine applicator, ensure that all parts of the equipment are in good condition and check that each part is securely installed. At the same time, prepare the required medicine solution and pour it into the water tank, ensuring that the medicine solution is sufficient and free of impurities. S2. Livestock guidance: Guide the livestock to be injected with medicine to the fence frame and make them stand with their backs to the top frame (1). During the guidance process, keep the movements gentle to avoid frightening the livestock and ensure that they can enter the fence frame smoothly and be between the two sets of inner clamps (15) to prepare for subsequent fixing operations. S3, body position restriction: The hind legs of the livestock are restricted by the convergence component, so that the hind legs of the livestock are restricted between the forked open columns (23), which effectively prevents the livestock from kicking people with their hind legs due to discomfort during the administration of medicine. The inner clamp (15) is driven to fit tightly against the hindquarters of the livestock by the translation component, thereby fixing the livestock’s body and keeping it stable during the administration of the medicine; S4. Medication infusion: After restricting the position of the livestock, insert the syringe's outlet end into the livestock's reproductive position and complete the medication infusion process through the pressure delivery component. S5. Equipment reset: After the medicine is injected, the inner clamp (15) is driven to move to release the livestock. After the livestock are released, each component is automatically reset to the initial state to prepare for the next injection operation.
