Description

Technical Field

[0001] This invention relates to the field of cattle breeding technology, and in particular to a stable and efficient marking device for cattle breeding. Background Technology

[0002] Ear tags are animal identification devices applied to the ears of livestock to identify their identity and record individual information. Their structure consists of a main tag (including the tag face, neck, and head) and a secondary tag. The main tag penetrates the ear and is fixed in place, while the tag face carries coded information. They are used on large and medium-sized livestock such as cattle, sheep, and pigs.

[0003] For example, patent application number CN202011149118.2 discloses "a marking device for cattle breeding", which includes an upper handle, a lower handle and an anti-slip pad. The feature is that the lower handle is provided on the lower side of the upper handle, and the anti-slip pad is glued to the outer side of the same end of the upper handle and the lower handle.

[0004] However, when using the above-mentioned device, if the cow's ear is passed between the handles for marking, the cow's ear may swing continuously, and the operator may not be able to control the feeding distance and force properly. The cow's ear may be easily broken, resulting in marking failure. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that when marking cattle ears by passing them through the handles, the cattle ears may swing continuously, making it difficult for workers to control the feeding distance and force, and the cattle ears are easily bent, resulting in marking failure. Therefore, this invention proposes a stable and efficient marking device for cattle farming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stable and efficient marking device for cattle breeding includes a clamping rod one, wherein a clamping rod two is hinged to the middle of the clamping rod one; It also includes a marking mechanism for marking cow ears. The marking mechanism includes two clamping plates symmetrically arranged between the left inner sides of clamping rod 1 and clamping rod 2. A connecting rod 1 is hinged to the right side of the clamping plates at their respective ends. The ends of the connecting rod 1 at their respective ends are fixedly connected to clamping rod 1 and clamping rod 2. A connecting rod 2 is hinged to the left side of the clamping plates at their respective ends. A slider is hinged to the ends of the connecting rod 2 at their respective ends. The ends of the sliders at their respective ends are slidably connected to clamping rod 1 and clamping rod 2. A spring 1 is fixedly installed on the left end of each slider. The left end of the spring 1 is fixedly connected to clamping rod 1 and clamping rod 2. It also includes a high-efficiency marking mechanism, which includes a movable plate that is slidably mounted on a clamping rod, and a striking post that is fixedly mounted at the lower end of the movable plate.

[0007] Preferably, an ear tag pin is fixedly installed at the lower end of the clamping rod, and ear tag clips are provided on the upper end of the clamping plate on the lower side, symmetrically corresponding to the ear tag pins. A rotating shaft is fixedly installed on the ends of the ear tag clips that are far apart from each other. The rotating shaft is rotatably installed on the clamping plate on the lower side, and a torsion spring is sleeved on the outer side of the rotating shaft.

[0008] Preferably, straightening strips are abutted and fitted on the side of the clamping plates that are close to each other on both sides. A connecting plate is slidably installed on the front end of each straightening strip. A guide rod is fixedly installed on the rear end of each connecting plate. A sliding groove plate is slidably installed through the rear end of each guide rod. The sliding groove plates are respectively fixedly installed on the ends of the clamping plates that are far apart from each other on both sides.

[0009] Preferably, each of the connecting plates has a movable frame slidably inserted into one of its opposite ends, and the movable frames are slidably installed on the opposite ends of the two sliding groove plates.

[0010] Preferably, inclined plates are slidably installed on the sliding groove plates on both sides corresponding to the movable frames. The left end of the inclined plate abuts against and fits against the movable frames on both sides, and top strips are fixedly installed on the inclined plates at the ends of clamp rod one and clamp rod two that are close to each other.

[0011] Preferably, each of the connecting plates has a push block abutting against and fitting on its left end. The push block is slidably mounted on the clamping plate, and each of the push blocks has a spring two fixedly mounted on its left end. The left end of the spring two is also fixedly mounted on the clamping plate.

[0012] Preferably, each of the clamping plates has a through groove at one end that is close to the other, and the cleaning ring is slidably installed in the through groove. An L-shaped groove is provided in the through groove corresponding to the cleaning ring.

[0013] Preferably, a positioning rod is slidably installed through the front end of the connecting plate corresponding to the straightening strip, the rear end of the positioning rod is inserted into the straightening strip, a support plate is slidably installed through the front end of the positioning rod, the support plate is fixedly installed on the front end of the connecting plate, and a spring is sleeved on the outer side of the positioning rod.

[0014] Preferably, a spring four is fixedly installed on the left end of the movable plate, and the left end of the spring four is fixedly installed on the clamping rod one. A blocking strip is abutted and fitted on the right end of the movable plate, and the blocking strip is slidably installed on the clamping rod one.

[0015] Preferably, a clamping bar is provided on the rear side of the clamping rod, and a connecting rod three is fixedly installed in the middle of the rear end of the clamping bar. The rear end of the connecting rod three is slidably installed on the clamping rod, and a spring five is sleeved on the outer side of the connecting rod three. The front and rear ends of the spring five are fixedly connected to the clamping bar and the clamping rod one, respectively.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the ear tag clips on both sides are rotated first, which drives the rotating shaft to rotate on the clamp plate, compresses the torsion spring, places the ear tag on the clamp plate, releases the ear tag clips, and drives the ear tag clips and rotating shaft to reset under the action of the torsion spring, clamping and fixing both ends of the ear tag on the clamp plate. This is beneficial for fixing the ear tag, preventing the ear tag from shifting during the marking process and causing marking failure, thus improving the marking accuracy.

[0017] 2. In this invention, the worker's palm passes between clamp rod one and clamp strip, and grips clamp rod one. The thickness of the palm will push clamp strip and connecting rod three to slide adaptively on clamp rod one, compressing spring five. The clamp strip is designed to easily clamp and fix the palm on clamp rod one, while the fingers grip clamp rod two. The worker holds clamp rod one and clamp rod two and aligns the cow ear between the clamp plates on both sides. At the same time, clamp rod one and clamp rod two are pressed down, causing the clamp plates on both sides to move closer to each other, and the ear tag needle to move closer to the ear tag clamped on the clamp plate. Finally, the ear tag needle passes through the cow ear and ear tag, fixing the ear tag on the cow ear, completing the marking work. The operation is simple and convenient.

[0018] 3. In this invention, after marking is completed, the hand holding clamp rod one and clamp rod two releases clamp rod two, and then the thumb of the hand holding clamp rod one and clamp rod two pushes the blocking strip outward to separate the blocking strip from the movable plate. Under the action of spring four, the movable plate and the impact post are pushed to slide rapidly on clamp rod one towards the connection between clamp rod one and clamp rod two. The impact post hits the connection between clamp rod one and clamp rod two, which helps clamp rod one and clamp rod two to quickly separate and reset. This avoids the situation in the traditional method where the reset spring is stuck between clamp rod one and clamp rod two, making it more difficult to press during marking. At the same time, it can also quickly reset after marking is completed, improving work efficiency.

[0019] 4. In this invention, the clamping strip facilitates the clamping and fixing of the palm and hand holding the clamping rod one, preventing the marking device from falling off when the fingers release the clamping rod two, thus ensuring stability.

[0020] 5. In this invention, when clamping rod one and clamping rod two approach each other, they also drive the clamping plates on both sides to approach synchronously. When the clamping plates on both sides approach each other, the left end of the clamping plates at the point where they approach each other will contact the cow's ear first. As clamping rod one and clamping rod two continue to rotate and approach each other, the clamping plates on both sides are subjected to pressure, which will drive connecting rod two and slider to slide outward on clamping rod one and clamping rod two adaptively, compressing spring one. At the same time, the clamping plates on both sides will also rotate adaptively on connecting rod one until the clamping plates on both sides are parallel. At this point, the ear tag needle passes through the upper clamping plate to complete the marking work on the cow's ear. The clamping plates on both sides are designed to clamp and flatten the cow's ear, avoiding the cow's ear from wrinkling and tilting during marking, which would cause the ear tag to be insecure after marking, thereby improving the marking quality.

[0021] 6. In this invention, when the clamping plates on both sides drive the connecting rod 2 and the slider to slide adaptively on the clamping rod 1 and clamping rod 2, the inclined plate will gradually approach the top bar and be squeezed by the top bar, pushing the inclined plate to slide backward on the slide plate. The inclined plate gradually separates from the movable frame. Under the action of the spring 2, it pushes the push block, connecting plate, movable frame, guide rod and straightening bar to move rapidly to the right. The straightening bar is set to straighten the folded cow ears and prevent the folded cow ears from causing the marking failure when marking the cow ears, thereby ensuring the marking quality.

[0022] 7. In this invention, the guide rod will drive the connecting plate and the straightening strip to move along the sliding track on the sliding plate, which will cause the straightening strip to automatically extend out of the groove of the clamping plate to automatically straighten the folded cow ear. After the straightening is completed, it will retract back to the right side of the clamping plate without affecting the clamping plate's clamping and flattening of the cow ear.

[0023] 8. In this invention, when a large amount of hair adheres to the straightening strip, the cleaning ring is first pushed out of the through groove through the L-shaped slide groove so that the cleaning ring contacts the right end of the straightening strip. Then, the cleaning ring is pushed backward along the L-shaped slide groove to remove the hair adhering to the straightening strip. The operation is simple and convenient.

[0024] 9. In this invention, pulling the positioning rod outward compresses the spring three, separating it from the straightening strip, and directly sliding the straightening strip out of the connecting plate, making it easy to remove the straightening strip from the connecting plate, facilitating the removal of hair and impurities adhering to the straightening strip, and benefiting subsequent use.

[0028] Reference Figures 1-12A stable and efficient marking device for cattle breeding includes a clamp rod 1, with a clamp rod 2 hinged to the middle of clamp rod 1. It also includes a marking mechanism for marking cattle ears. The marking mechanism comprises two clamping plates 3 symmetrically arranged between the left inner sides of clamp rod 1 and clamp rod 2. A connecting rod 4 is hinged to the right side of each clamping plate 3 at its opposite end. The opposite ends of connecting rod 4 are fixedly connected to clamp rod 1 and clamp rod 2, respectively. A connecting rod 5 is hinged to the left side of each clamping plate 3 at its opposite end. A slider 6 is hinged to the opposite end of each connecting rod 5. The opposite ends of slider 6 are slidably connected to clamp rod 1 and clamp rod 2, respectively. Spring 7 is fixedly installed on the left end of slider 6. The left end of spring 7 is fixedly connected to clamp rod 1 and clamp rod 2 respectively. Ear tag pin 8 is fixedly installed on the lower end of clamp rod 1. Ear tag clips 9 are symmetrically provided on the upper end of the lower clamping plate 3, corresponding to ear tag pin 8. A rotating shaft 10 is fixedly installed on the opposite end of the ear tag clips 9. The rotating shaft 10 is rotatably mounted on the lower clamping plate 3. A torsion spring 11 is sleeved on the outer side of the rotating shaft 10. Straightening strips 12 are abutted and fitted on the side of the clamping plates 3 that are close to each other. A connecting plate 13 is slidably installed on the front end of the straightening strip 12. A guide rod 14 is fixedly installed on the rear end of the connecting plate 13. A sliding groove plate 15 is slidably installed through the rear end of the connecting plate 14. The sliding groove plate 15 is fixedly installed on the opposite ends of the two side clamping plates 3. Movable frames 16 are slidably inserted on the opposite ends of the connecting plates 13. The movable frames 16 are slidably installed on the opposite ends of the two side sliding groove plates 15. Inclined blocks 17 are slidably installed on the sliding groove plates 15 on both sides corresponding to the movable frames 16. The left ends of the inclined blocks 17 abut against and fit against the movable frames 16 on both sides. Top strips 18 are fixedly installed on the opposite ends of the clamping rods 1 and 2 corresponding to the inclined blocks 17. Push blocks 19 are abutted against and fit against the left ends of the connecting plates 13. Push block 19 is slidably mounted on clamping plate 3. Spring 20 is fixedly mounted on the left end of push block 19. Spring 20 is fixedly mounted on the left end of clamping plate 3. Through groove 22 is opened at the close ends of clamping plate 3. Cleaning ring 21 is slidably mounted in through groove 22. L-shaped groove 23 is opened in through groove 22 corresponding to cleaning ring 21. Positioning rod 24 is slidably mounted through the front end of connecting plate 13 corresponding to straightening strip 12. The rear end of positioning rod 24 is inserted into straightening strip 12. Support plate 25 is slidably mounted through the front end of positioning rod 24. Support plate 25 is fixedly mounted on the front end of connecting plate 13. Spring 3 26 is sleeved on the outer side of positioning rod 24. During operation, when clamping rod 1 and clamping rod 2 approach each other, they also cause the clamping plates 3 on both sides to approach synchronously. When the clamping plates 3 on both sides approach each other, the left end of the clamping plates 3 at the point where they approach each other will contact the bull's ear first. As clamping rod 1 and clamping rod 2 continue to rotate and approach each other, the clamping plates 3 on both sides are subjected to pressure, which will cause connecting rod 2 5 and slider 6 to adaptively slide outward on clamping rod 1 and clamping rod 2 2, compressing spring 1 7. At the same time, the clamping plates 3 on both sides will also adaptively rotate on connecting rod 1 4 until the clamping plates 3 on both sides are parallel, at which point the ear tag needle 8 passes through the upper clamping plate 3 completely. The marking process for paired cow ears utilizes clamping plates 3 on both sides to clamp and flatten the cow ears, preventing wrinkles and tilting during marking and ensuring the ear tags are securely applied, thus improving marking quality. When the clamping plates 3 drive the connecting rod 5 and slider 6 to slide adaptively on clamping rod 1 and clamping rod 2, the inclined plate 17 gradually approaches the top bar 18 and is subjected to the squeezing force of the top bar 18, pushing the inclined plate 17 backward on the slide plate 15. The inclined plate 17 gradually separates from the movable frame 16, and under the action of spring 20, pushes the push block 19, connecting plate 13, and movable... The frame 16, guide rod 14, and straightening bar 12 move rapidly to the right. The straightening bar 12 facilitates the straightening of the folded cow ears, preventing marking failures caused by the folded cow ears during marking, thus ensuring marking quality. The guide rod 14 drives the connecting plate 13 and the straightening bar 12 to move along the slide track on the slide plate 15, causing the straightening bar 12 to automatically extend from the groove of the clamping plate 3 to automatically straighten the folded cow ears. After straightening, it retracts back to the right side of the clamping plate 3 without affecting the clamping and flattening of the cow ears by the clamping plate 3. When large amounts of... When measuring hair, first push the cleaning ring 21 out of the through groove 22 through the L-shaped slide 23 so that the cleaning ring 21 contacts the right end of the straightening strip 12. Then push the cleaning ring 21 backward along the L-shaped slide 23 to remove the hair adhering to the straightening strip 12. The operation is simple and convenient. Pull the positioning rod 24 outward to compress the spring 3 26 to separate it from the straightening strip 12. The straightening strip 12 can be directly slid out of the connecting plate 13, which makes it easy to remove the straightening strip 12 from the connecting plate 13. This facilitates the removal of hair and impurities adhering to the straightening strip 12 and is beneficial for subsequent use.

[0029] As an embodiment of the present invention, a high-efficiency mechanism for high-efficiency marking is also provided. The high-efficiency mechanism includes a movable plate 27 that is slidably mounted on a clamping rod 1. A strike post 28 is fixedly mounted on the lower end of the movable plate 27. A spring 4 29 is fixedly mounted on the left end of the movable plate 27. The left end of the spring 4 29 is fixedly mounted on the clamping rod 1. A blocking strip 30 is abutted and fitted on the right end of the movable plate 27. The blocking strip 30 is slidably mounted on the clamping rod 1. A clamping strip 31 is provided on the rear side of the clamping rod 1. A connecting rod 32 is fixedly mounted on the middle of the rear end of the clamping strip 31. The rear end of the connecting rod 32 is slidably mounted on the clamping rod 1. A spring 5 33 is sleeved on the outer side of the connecting rod 32. The front and rear ends of the spring 5 33 are fixedly connected to the clamping strip 31 and the clamping rod 1, respectively. During operation, first rotate the ear tag clips 9 on both sides, causing the rotating shaft 10 to rotate on the clamping plate 3, compressing the torsion spring 11. Place the ear tag on the clamping plate 3, then release the ear tag clips 9. Under the action of the torsion spring 11, the ear tag clips 9 and the rotating shaft 10 will return to their original positions, clamping and fixing both ends of the ear tag on the clamping plate 3. This facilitates the fixation of the ear tag, prevents ear tag displacement during marking, and improves marking accuracy. The operator's palm passes between the clamping rod 1 and the clamping strip 31. Holding clamp rod 1, the thickness of the palm will push clamp strip 31 and connecting rod 32 to slide adaptively on clamp rod 1, compressing spring 5 33. The clamp strip 31 is designed to easily clamp and fix the palm on clamp rod 1, with fingers gripping clamp rod 2. The worker holds clamp rod 1 and clamp rod 2 and aligns the ear with the clamp plates 3 on both sides. At the same time, pressing clamp rod 1 and clamp rod 2 causes the clamp plates 3 on both sides to move closer together, and the ear tag needle 8 moves closer to the ear tag clamped on the clamp plate 3. Finally, the ear tag is inserted. The needle 8 passes through the cow's ear and ear tag, fixing the ear tag to the cow's ear and completing the marking work. The operation is simple and convenient. After marking is completed, the hands holding clamp 1 and clamp 2 release clamp 2, and then the thumbs of the hands holding clamp 1 and clamp 2 push the blocking strip 30 outward, separating the blocking strip 30 from the movable plate 27. Under the action of spring 4 29, the movable plate 27 and the striking post 28 are pushed to slide rapidly on clamp 1 towards the connection between clamp 1 and clamp 2 2. The striking post 28 strikes... The connection between clamp rod 1 and clamp rod 2 facilitates quick separation and reset of clamp rod 1 and clamp rod 2, avoiding the situation where the traditional method of setting a reset spring and getting stuck between clamp rod 1 and clamp rod 2 makes it difficult to press during marking. At the same time, it can also quickly reset after marking, improving work efficiency. The clamping bar 31 is designed to hold and fix the hand holding clamp rod 1, preventing the marking device from falling off when the fingers release clamp rod 2, thus ensuring stability.

[0030] Working principle: In use, the ear tag clips 9 on both sides are rotated first, causing the rotating shaft 10 to rotate on the clamping plate 3, compressing the torsion spring 11. The ear tag is then placed on the clamping plate 3. The ear tag clips 9 are released, and under the action of the torsion spring 11, the ear tag clips 9 and the rotating shaft 10 are reset, clamping and fixing both ends of the ear tag on the clamping plate 3. This facilitates the fixing of the ear tag and prevents the ear tag from shifting during the marking process, thus improving the marking accuracy. The operator's palm passes between the clamping rod 1 and the clamping strip 31, and grips the clamping rod 1. The thickness of the palm will push the clamping strip 31 and the connecting rod 32 to slide adaptively on the clamping rod 1, compressing the spring 5 33. The clamping strip 31 is designed to easily clamp and fix the palm on the clamping rod 1. The fingers grip the clamping rod 2, and the operator holds the clamping rod 1. 1. Clamping lever 2 aligns the cow's ear with the clamping plates 3 on both sides. Simultaneously pressing clamping levers 1 and 2 causes the clamping plates 3 to move closer together, and the ear tag needle 8 moves closer to the ear tag held on the clamping plate 3. Finally, the ear tag needle 8 passes through the cow's ear and ear tag, fixing the ear tag to the cow's ear, completing the marking process. The operation is simple and convenient. After marking, the hand holding clamping levers 1 and 2 releases clamping lever 2, and then the thumb of the hand holding clamping levers 1 and 2 pushes the blocking strip 30 outward, separating the blocking strip 30 from the movable plate 27. Under the action of spring 4 29, the movable plate 27 and the striking post 28 are pushed to slide rapidly on clamping lever 1 towards the connection point of clamping levers 1 and 2. The striking post 28 strikes the connection point of clamping levers 1 and 2, which helps to make clamping levers 1 and 2... The quick separation and reset of clamp rod 2 avoids the problem of traditional clamp rods 1 and 2 being stuck between them, which makes marking difficult. It also allows for quick reset after marking, improving work efficiency. The clamping bar 31 secures the hand holding clamp rod 1, preventing the marking device from falling when the fingers release clamp rod 2, ensuring stability. When clamp rods 1 and 2 approach each other, the clamping plates 3 on both sides also approach synchronously. When the clamping plates 3 approach each other, the left end of the side that approaches first contacts the bull's ear. As clamp rods 1 and 2 continue to rotate and approach each other, the clamping plates 3 are under pressure, which causes connecting rod 2 5 and slider 6 to adaptively clamp. The first rod 1 and the second clamping rod 2 slide outwards, compressing the first spring 7. At the same time, the clamping plates 3 on both sides will also rotate adaptively on the connecting rod 4 until the clamping plates 3 on both sides are parallel. At this point, the ear tag needle 8 passes through the upper clamping plate 3 to complete the marking work on the cow's ear. The clamping plates 3 on both sides are designed to clamp and flatten the cow's ear, preventing the cow's ear from wrinkling and tilting during marking, which would cause the ear tag to be insecure after marking, thereby improving the marking quality. When the clamping plates 3 on both sides drive the second connecting rod 5 and the slider 6 to slide adaptively on the clamping rod 1 and the second clamping rod 2, the inclined plate 17 will gradually approach the top bar 18 and be squeezed by the top bar 18, pushing the inclined plate 17 to slide backward on the slide plate 15. The inclined plate 17 gradually separates from the movable frame 16. Under the action of the second spring 20,The pusher block 19, connecting plate 13, movable frame 16, guide rod 14, and straightening bar 12 are pushed to the right at high speed. The straightening bar 12 is designed to straighten the folded cow ears, preventing marking failures caused by the folded cow ears during marking, thus ensuring marking quality. The guide rod 14 drives the connecting plate 13 and the straightening bar 12 to move along the slide track on the slide plate 15, which in turn causes the straightening bar 12 to automatically extend from the groove of the clamping plate 3 to automatically straighten the folded cow ears. After straightening, it retracts back to the right side of the clamping plate 3 without affecting the clamping and flattening of the cow ears by the clamping plate 3. When a large amount of hair adheres to the straightening strip 12, the cleaning ring 21 is first pushed out of the through groove 22 via the L-shaped slide groove 23, so that the cleaning ring 21 contacts the right end of the straightening strip 12. Then, the cleaning ring 21 is pushed backward along the L-shaped slide groove 23 to remove the hair adhering to the straightening strip 12. The operation is simple and convenient. Pulling the positioning rod 24 outward compresses the spring 3 26, separating it from the straightening strip 12, and the straightening strip 12 can be directly slid out of the connecting plate 13, making it easy to remove the straightening strip 12 from the connecting plate 13. This facilitates the removal of hair and impurities adhering to the straightening strip 12, which is beneficial for subsequent use.
