Description

Technical Field

[0001] The invention belongs to the technical field of ear tag clamps, in particular to a multifunctional ear tag clamp for large livestock. Background Art

[0002] The main function of ear tags is to record the activity patterns, epidemic prevention status and basic information of livestock, and it even plays an important role in the subsequent tracking of the quality source of meat products. The application of ear tags greatly facilitates the management of livestock; ear tagging of livestock has become a frequently used operation method in the animal husbandry industry. When ear tagging livestock, ear tag pliers are needed to penetrate the ear tag head of the main tag through the livestock's ear, embed the auxiliary tag, fix the ear tag, and leave the ear tag neck in the perforation to complete the tagging.

[0003] When the existing ear tag clamp is in use, the nail hole needle cannot always be perpendicular to the auxiliary tag. Especially when marking large livestock, the main tag neck and the auxiliary tag are not perpendicular, which can easily cause the wound on the livestock's ear to increase. In addition, after the marking is completed, the ear tag clamp cannot be quickly detached for the next marking. The nail hole needle cannot be cleaned and disinfected in time before and after marking, which can easily cause livestock wound infection. Summary of the invention

[0004] In order to solve the above-mentioned existing problems, the present invention provides a multifunctional ear tag clamp for large livestock, which can always keep the main tag neck and the auxiliary tag vertical, and can clean and disinfect the nail hole needle in time before and after marking. At the same time, after marking, the ear tag clamp can be quickly detached from the ear tag through the rebound structure, and is suitable for ear tags of various sizes.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: the present invention provides a multifunctional ear tag clamp for large livestock, comprising an elastic clamping type lower clamping plate assembly, the upper part of which is slidably provided with a self-rebounding upper clamping plate assembly, the elastic clamping type lower clamping plate assembly and the self-rebounding upper clamping plate assembly are connected with an adjustable clamp assembly, wherein the elastic clamping type lower clamping plate assembly comprises a first clamping plate and a clamping mechanism, the first clamping plate is movably provided at the end of the adjustable clamping plate assembly, and the clamping mechanism is provided on the first clamping plate; Furthermore, the self-rebounding upper clamping plate assembly includes a second clamping plate and a pressing mechanism, the second clamping plate is movably arranged at the end of the adjustable clamping assembly, a sliding positioning rod is provided at the lower part of the second clamping plate, the sliding positioning rod passes through and is slidably arranged on the first clamping plate, the second clamping plate is slidably arranged above the first clamping plate through the sliding positioning rod, a return spring is connected between the first clamping plate and the second clamping plate, the return spring is sleeved on the outer side of the sliding positioning rod, the pressing mechanism is arranged at the lower part of the second clamping plate, and a disinfection box is provided at the upper part of the second clamping plate.

[0006] Preferably, the first clamping plate and the second clamping plate are in the shape of a trapezoidal column, the adjustable clamp assembly is arranged on one side of the short side of the first clamping plate and the second clamping plate, the first clamping plate and the second clamping plate are symmetrically arranged up and down, and the upper part of the first clamping plate and the lower part of the second clamping plate are symmetrically provided with clamping grooves respectively; Further, movable grooves are provided on the four corners of the first clamping plate, the sliding positioning rod is slidably provided in the movable grooves, a mounting groove is provided in the middle of the first clamping plate, the mounting groove runs through one side of the long side of the first clamping plate, the mounting groove is provided inside the clamping groove, and the mounting groove facilitates the installation of the auxiliary mark; When ear-tagging large livestock, since the ears of livestock are of different sizes, a first clamping plate and a second clamping plate in the shape of a trapezoidal column are used, with the long side of the trapezoid facing outward to accommodate ears of larger sizes. The first clamping plate, the second clamping plate and the sliding positioning rod limit the movement of the livestock's ears to a certain extent, laying the foundation for safe and accurate ear-tagging.

[0007] Further, the clamping mechanism includes a fixed plate, a clamping arc plate and a sliding rod, the fixed plate is symmetrically arranged on the upper part of the first clamping plate, the clamping arc plate is symmetrically arranged on the upper part of the first clamping plate, the clamping arc plate is slidably arranged between the assembly groove and the fixed plate, the sliding rod is arranged on the outer side wall of the clamping arc plate, the sliding rod penetrates and slides on the fixed plate, a clamping spring is connected between the clamping arc plate and the fixed plate, the clamping spring is arranged on the outer side of the sliding rod, the clamping arc plate is connected to a guide plate on the side of the long side of the first clamping plate, and the guide plate is inclined; When in use, when the auxiliary mark is pushed horizontally between the symmetrical clamping arc plates, the edge of the auxiliary mark will first contact the guide plate and squeeze the symmetrical guide plates away from each other until the auxiliary mark is inserted into the inner side of the clamping arc plate. The sliding rod limits the clamping arc plate to slide horizontally on both sides, and the clamping spring provides elastic squeezing force so that the clamping arc plate squeezes and clamps the auxiliary mark. It is suitable for auxiliary mark sizes of various specifications and is easy to install.

[0008] Furthermore, a transition arc surface is provided on the relative arc surface of the clamping arc plate, and the transition arc surface is inclined. After the marking is completed, under the instantaneous elastic force of the return spring, the auxiliary mark is quickly moved up relative to the first clamping plate and disengaged from the clamping of the opposite surface of the clamping arc plate. Even if the transition arc surface contacts the lower edge of the auxiliary mark, it will not be able to clamp the auxiliary mark because it is an inclined surface, and under the push of the clamping spring, the lower edge of the auxiliary mark slides up quickly along the inclined transition arc surface to leave the first clamping plate, thereby accelerating the detachment time of the auxiliary mark; the end faces of the symmetrical clamping arc plates are rotatably provided with separation push plates, and the two separation push plates are rotatably connected to each other. When the first clamping plate and the second clamping plate are squeezed against each other, the ears of the livestock squeeze the rotating connection of the separation push plates, and the symmetrical separation push plates squeeze and push the clamping arc plates to both sides, thereby loosening the clamping of the auxiliary mark and facilitating the removal of the auxiliary mark.

[0009] Furthermore, the lower wall of the second clamping plate is not penetrated by a clearance groove, a nail hole needle is provided at the center of the clearance groove, the axis of the nail hole needle passes through the center of the circular arc trajectory of the clamping arc plate, the pressing mechanism comprises a pushing spring, a pushing plate and a liquid passing cylinder, the pushing springs are all arranged in the clearance groove, the circumference of the pushing springs is evenly distributed on the outside of the nail hole needle, the pushing plate is connected to the lower part of the pushing spring, the coverage area of ​​the pushing plate is larger than the coverage area of ​​the symmetrical outer wall trajectory of the clamping arc plate, a through hole is penetrated at the center of the pushing plate, the nail hole needle is penetrated in the through hole, the pushing plate is slid up and down and is arranged below the second clamping plate, the liquid passing cylinder is arranged on the upper part of the pushing plate, and the liquid passing cylinder is symmetrically arranged on both sides of the nail hole needle; Further, the liquid-passing cylinder is slidably arranged inside the second clamping plate, half of the liquid-passing cylinder is arranged in the through hole, the liquid-passing cylinder is obliquely connected to the side of the nail hole needle with a liquid-separating cylinder, the upper end of the liquid-passing cylinder is provided with a liquid-passing groove, the liquid-passing groove faces the nail hole needle, and the upper end of the liquid-passing cylinder is horizontally provided with a closing plate, and the covering area of ​​the closing plate is larger than the cross-sectional area of ​​the liquid-passing cylinder; Preferably, the distance from the upper end of the liquid separation cylinder to the bottom surface of the clearance groove is greater than the distance from the upper wall of the push plate to the lower wall of the second clamping plate, and when the liquid passing cylinder moves upward, the liquid passing cylinder is connected to the disinfection box through the liquid passing groove; When the main mark is inserted onto the nail hole needle, the main mark can be quickly pressed with force to move the push plate up, push the spring to compress, drive the liquid-passing cylinder to move up, so that the closing plate in the disinfection box no longer blocks the connecting hole between the disinfection box and the liquid-passing cylinder, and then the disinfectant in the disinfection box flows into the liquid-passing cylinder through the liquid-passing groove. Since the liquid-separating cylinder and the liquid-passing groove are both facing the nail hole needle, when the disinfectant flows into the liquid-passing cylinder, a part of the disinfectant flows out through the liquid-separating cylinder and directly flows onto the nail hole needle, and another part of the disinfectant flows out through the liquid-passing cylinder and flows onto the main mark through the through hole. The disinfectant flows through the gap between the main mark and the nail hole needle to clean and disinfect the nail hole needle before marking. After the push plate is pressed once, the push plate is reset under the elastic action of the push spring, and then the closing plate is blocked between the disinfection box and the liquid-passing cylinder again to prevent the outflow of the disinfectant; and in the marking process, the main mark squeezes the push plate again to connect the disinfection box with the liquid-passing cylinder, and the disinfectant flows to the nail hole needle and the main mark respectively, and some disinfectant remains in the main mark. After the marking is completed, the nail hole needle quickly leaves the main mark under the push of the push plate, and its needle tip moves upward relative to the main mark. The disinfectant remaining in the main mark acts on the nail hole needle again, avoiding impurities such as livestock blood stains remaining on the nail hole needle, thereby achieving the technical effect of timely cleaning and disinfecting the nail hole needle before and after marking.

[0010] Furthermore, the adjustable clamp assembly includes an upper pressure plate, a lower pressure plate, an upper handle, a lower handle and a pressing slide plate, the upper pressure plate is horizontally arranged above the second clamp plate, the lower pressure plate is horizontally arranged below the first clamp plate, the upper handle is connected to a side of the lower pressure plate away from the first clamp plate, the upper handle is inclined upward, the lower handle is connected to a side of the upper pressure plate away from the second clamp plate, the lower handle is inclined downward, the upper handle and the lower handle are cross-rotatingly connected, an auxiliary spring is connected between the upper handle and the lower handle, the pressing slide plate is symmetrically arranged at the lower part of the upper pressure plate and the upper part of the lower pressure plate, and the pressing slide plate and the upper pressure plate The upper and lower pressure plates are rotatably connected, and the pressing slide plate is slidably arranged in the clamping groove; when in use, the upper handle and the lower handle are held and pressed against each other, the auxiliary spring is compressed, so that the upper and lower pressure plates are close to each other, and the front ends of the upper and lower pressure plates are close to each other along a circular arc trajectory, so that the pressing slide plate squeezes the first clamping plate and the second clamping plate close to each other, and the upper and lower pressure plates are rotatably connected to the pressing slide plate, respectively. During this process, the pressing slide plate adaptively slides in the clamping groove. Since the sliding positioning rod slides in the movable groove, the first clamping plate and the second clamping plate are restricted to be always parallel to each other, thereby ensuring that the nail hole needle is always perpendicular to the auxiliary mark during the marking process.

[0011] Furthermore, the upper handle and the lower handle are rotatably provided with extension rods at one end away from the upper pressure plate, and two groups of the extension rods are respectively provided at the upper part of the upper handle and the lower part of the lower handle, and the extension rods are respectively connected to the upper handle and the lower handle through magnetic blocks; When marking livestock with thick ears, the extension rod can be flipped open to indirectly extend the length of the upper handle and the lower handle. According to the principle of leverage, the torque of the upper handle and the lower handle is increased, making marking more labor-saving. When not in use, the extension rod can be flipped back into the upper handle and the lower handle, and the magnetic block inside will automatically close and be stored.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The multifunctional ear tag pliers for large livestock provided by the present invention are provided with a first clamp and a second clamp in the shape of a trapezoidal column. According to the different sizes of livestock ears, the first clamp and the second clamp have one side of the trapezoidal long side facing outward, which can accommodate ears of larger sizes. The first clamp, the second clamp and the sliding positioning rod limit the movement of livestock ears to a certain extent, laying a foundation for safe and accurate ear tagging; at the same time, the sliding positioning rod limits the first clamp and the second clamp to be always parallel to each other, ensuring that the nail hole needle is always perpendicular to the auxiliary tag during the tagging process, avoiding excessive wounds on livestock ears; 2. By setting the push spring, the push plate, the liquid-passing cylinder, the closing plate and the disinfection box, before marking, the push plate pushes the liquid-passing cylinder upward, so that the closing plate in the disinfection box no longer blocks the connecting hole between the disinfection box and the liquid-passing cylinder, and then the disinfectant in the disinfection box flows into the liquid-passing cylinder through the liquid-passing groove, wherein a part of the disinfectant flows out through the liquid-separating cylinder and directly flows to the nail hole needle, and another part of the disinfectant flows out through the liquid-passing cylinder and flows to the main mark through the through hole, and the disinfectant flows through the gap between the main mark and the nail hole needle. The nail hole needle is cleaned and disinfected before marking; during the marking process, the main mark squeezes the push plate again, so that the disinfection box is connected with the liquid cylinder, and the disinfectant flows to the nail hole needle and the main mark respectively, and some disinfectant remains in the main mark; after the marking is completed, the nail hole needle quickly leaves the main mark under the push of the push plate, and its needle tip moves upward relative to the main mark, and the disinfectant remaining in the main mark acts on the nail hole needle again, avoiding impurities such as livestock blood on the nail hole needle, and achieving the technical effect of timely cleaning and disinfecting the nail hole needle before and after marking; 3. A clamping mechanism is set up, which adopts the pre-action principle to facilitate the installation of the auxiliary mark. When the auxiliary mark is pushed into the clamping arc plate, the edge of the auxiliary mark contacts the guide plate first, and squeezes the symmetrical guide plates away from each other until the auxiliary mark is inserted into the inner side of the clamping arc plate. The clamping spring provides elastic squeezing force, so that the clamping arc plate squeezes and clamps the auxiliary mark. It is suitable for various auxiliary mark sizes and is easy to install. 4. A separation push plate is provided. When the first clamping plate and the second clamping plate are pressed against each other, the symmetrical separation push plates squeeze and push the clamping arc plates to both sides, thereby loosening the clamping of the auxiliary label, making it easier for the auxiliary label to be removed. Under the joint action of the auxiliary spring and the return spring, the first clamping plate and the second clamping plate quickly move away from each other on the upper and lower sides. The instantaneous elastic force causes the auxiliary label to quickly move upward relative to the first clamping plate and break away from the clamping of the opposite surface of the clamping arc plates. Even if the transition arc surface contacts the lower edge of the auxiliary label, it will not be able to clamp the auxiliary label because it is set as an inclined surface. Under the push of the clamping spring, the lower edge of the auxiliary label quickly slides up along the inclined transition arc surface and leaves the first clamping plate. Under the elastic thrust of the push spring, the push plate pushes the main label to separate from the second clamping plate, accelerating the time for the nail hole needle to leave the main label, thereby quickly separating the ear tag clamp from the ear tag after marking, avoiding tearing the ears of livestock. 5. When the auxiliary mark is pushed horizontally between the symmetrical clamping arc plates, the edge of the auxiliary mark will contact the guide plate first and squeeze the symmetrical guide plates away from each other until the auxiliary mark is inserted into the inner side of the clamping arc plate. The sliding rod limits the clamping arc plate to slide horizontally on both sides. The clamping spring provides elastic squeezing force, so that the clamping arc plate squeezes and clamps the auxiliary mark. It is suitable for auxiliary mark sizes of various specifications and is easy to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Working principle and workflow: When in use, the staff injects disinfectant into the disinfection box 8, installs the auxiliary label on the clamping mechanism 5, inserts the main label on the nail hole needle 64, and adopts the pre-action principle. When the auxiliary label is horizontally pushed between the symmetrical clamping arc plates 52, the edge of the auxiliary label first contacts with the guide plate 53, and squeezes the symmetrical guide plates 53 away from each other until the auxiliary label is inserted into the inner side of the clamping arc plate 52. The sliding rod 54 restricts the clamping arc plate 52 to slide horizontally to both sides, and the clamping spring 55 provides elastic squeezing force, so that the clamping arc plate 52 squeezes and clamps the auxiliary label. At this time, the upper end rotation point of the separation push plate 57 is still higher than the upper end surface of the clamping arc plate 52, which is suitable for auxiliary label sizes of various specifications; When the main mark is inserted into the nail hole needle 64, the main mark can be pressed quickly and forcefully to move the push plate 72 upward, push the spring 71 to compress, and drive the liquid cylinder 73 to move upward, so that the closing plate 731 in the disinfection box 8 no longer blocks the connecting hole between the disinfection box 8 and the liquid cylinder 73, and then the disinfectant in the disinfection box 8 flows into the liquid cylinder 73 through the liquid groove 732. Since the liquid separation cylinder 733 and the liquid groove 732 are both facing the nail hole needle 64, when the disinfectant flows into the liquid cylinder 73, a part of the disinfectant is The liquid flows out through the liquid separator 733 and directly flows onto the nail hole needle 64. Another part of the disinfectant flows out through the liquid passing cylinder 73 and flows onto the main mark through the through hole 74. The disinfectant flows through the gap between the main mark and the nail hole needle 64 to clean and disinfect the nail hole needle 64 before marking. After the push plate 72 is pressed once, the push plate 72 is reset under the elastic action of the push spring 71, so that the closing plate 731 is blocked again between the disinfection box 8 and the liquid passing cylinder 73 to prevent the disinfectant from flowing out.

[0022] When ear-tagging large livestock, since the ears of livestock vary in size, a first clamping plate 4 and a second clamping plate 6 in the shape of a trapezoidal column are used, with the long side of the trapezoid facing outwards, so as to accommodate ears of larger sizes. The first clamping plate 4, the second clamping plate 6 and the sliding positioning rod 61 restrict the movement of the livestock ears to a certain extent, thus laying a foundation for safe and accurate ear-tagging. Place the ear of the livestock between the auxiliary mark and the nail hole needle 64, hold the upper handle 34 and the lower handle 33 and press them against each other, the auxiliary spring 35 is compressed, so that the upper pressing plate 31 and the lower pressing plate 32 are close to each other, and the front ends of the upper pressing plate 31 and the lower pressing plate 32 are close to each other along an arc trajectory, so that the pressing slide plate 37 squeezes the first clamping plate 4 and the second clamping plate 6 to be close to each other, and the upper pressing plate 31 and the lower pressing plate 32 are respectively connected to the pressing slide plate 37 for rotation. During this process, the pressing slide plate 37 adaptively slides in the clamping groove 9. Since the sliding positioning rod 61 slides in the movable groove 41, the first clamping plate 4 and the second clamping plate 6 are always parallel to each other, ensuring that the nail hole needle 64 is always perpendicular to the auxiliary mark during the marking process; The first clamping plate 4 and the second clamping plate 6 are close to each other, and the return spring 62 is compressed until the nail hole needle 64 passes through the ear of the livestock, so that the neck of the main mark is inserted into the auxiliary mark. In this process, the main mark squeezes the push plate 72 again, so that the disinfection box 8 is connected with the liquid cylinder 73, and the disinfectant flows to the nail hole needle 64 and the main mark respectively, and some disinfectant remains in the main mark; when pressing down, the ear of the livestock squeezes the rotating connection of the separation push plate 57, and the symmetrical separation push plate 57 squeezes and pushes the clamping arc plate 52 to both sides, thereby loosening the clamping of the auxiliary mark. At this time, the main mark is nailed into the auxiliary mark, and then the upper handle 34 and the lower handle 33 are loosened, and under the joint action of the auxiliary spring 35 and the return spring 62 The first clamping plate 4 and the second clamping plate 6 quickly move away from the upper and lower sides, and the instantaneous elastic force causes the auxiliary tag to move up quickly relative to the first clamping plate 4 and break away from the clamping of the opposite surface of the clamping arc plate 52. Even if the transition arc surface 56 contacts the lower edge of the auxiliary tag, it will not be able to clamp the auxiliary tag because it is set as an inclined surface, and under the push of the clamping spring 55, the lower edge of the auxiliary tag quickly slides up along the inclined transition arc surface 56 and leaves the first clamping plate 4. Under the elastic thrust of the pushing spring 71, the pushing plate 72 pushes the main tag to break away from the second clamping plate 6, which accelerates the time for the nail hole needle 64 to leave the main tag, thereby quickly separating the ear tag clamp from the ear tag after marking to avoid tearing the ears of livestock.

[0023] When marking livestock with thick ears and requiring greater force, the extension rod 36 can be flipped open to indirectly extend the length of the upper handle 34 and the lower handle 33. According to the principle of leverage, the torque of the upper handle 34 and the lower handle 33 is increased, making marking more labor-saving. When not in use, the extension rod 36 can be flipped back into the upper handle 34 and the lower handle 33, and the magnetic block inside is automatically attracted and stored.
