Description

Technical Field

[0001] This invention relates to the field of animal marking technology, specifically to an ear tagging device for livestock breeding. Background Technology

[0002] Livestock farming falls under the category of biological industry. In livestock farming, to strengthen the management of each animal and facilitate the classification of each animal's growth cycle and physical condition by managers, tags need to be installed on the animal's ears. This allows various data to be recorded during the animal's growth process, enabling staff to adjust feeding methods in a timely manner based on the animal's physical condition, ensuring better growth for each animal. Currently, when tagging livestock, tag pliers are generally used to fix the tag to the animal's ear. When tagging, the tag insert and tag plate are placed on the upper and lower sides of the tag pliers, and the animal's ear is placed in the middle of the tag pliers. Pressing the tag pliers will fix the tag to the surface of the animal's ear.

[0003] However, existing ear tagging devices for livestock farming use a pressing method for tagging, which is slow and can easily cause pain to the animals. In addition, the tagging position is prone to deviation, and it cannot tag vertically. After tagging, the damaged area of ​​the pig's ear cannot be disinfected. The environment of the farm is heavily polluted, making the damaged area of ​​the pig's ear prone to infection, which affects the tagging effect. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This type of ear tagging device for livestock farming, through the setting of a power storage mechanism, allows for the following steps: When ear tagging of livestock is required, the pressing block is first pressed down. At this time, because the limiting rod is inserted into the limiting hole, it can limit the first moving block. The moving rod will not move downward, causing the first spring to be gradually compressed and storing power. At the same time, when the pressing block moves downward, it can slide down along the slope, pushing the limiting block into the mounting cover. The second spring is compressed. When the pressing block passes the limiting block, the top of the pressing block can abut against the bottom of the limiting block, thereby limiting the pressing block and preventing it from moving upward and returning to its original position. Next, the auxiliary tag is clamped and fixed on the pressure plate, the main tag is placed on the ejector pin, and then the handle is held by hand and pressed down. The two pressing blocks move closer to each other, and at the same time, the moving plate drives the two pressing rings to move closer to each other. The fourth spring is gradually compressed, and when the pressing ring comes into contact with the animal's ear, it clamps and limits the position, which can achieve a positioning effect and ensure more accurate marking. Then, the moving plate is turned so that the limiting rod is pulled out of the limiting hole. At the same time, the third spring is stretched. At this time, the first moving block is no longer limited, and the second moving block can move downward quickly under the action of the first spring. At the same time, the moving rod and the first moving block drive the pin and the main label to move downward quickly and insert into the auxiliary label after passing through the ear, realizing a fast marking operation, which is more convenient and faster, reduces animal pain, and ensures vertical marking, resulting in better marking effect.

[0017] This livestock ear tagging device, through the inclusion of a disinfection mechanism, works as follows: During tagging, when two squeezing blocks move closer together, an L-shaped block drives a sliding block downwards. This creates negative pressure above the sliding block within the working chamber. Simultaneously, the first one-way valve closes and the second one-way valve opens, allowing disinfectant stored in the reservoir to enter the working chamber through a second flexible tube. After tagging, releasing the squeezing blocks causes the two moving plates to move away from each other under the action of a fourth spring. This also causes the two pressure rings to move away from each other and detach from the ear. Furthermore, the L-shaped plate moves the ejector pin away from the pressure plate and detaches it from the ear, reducing animal pain and improving tagging effectiveness. Simultaneously, the L-shaped block drives the sliding block to reset, squeezing the disinfectant within the working chamber. The first one-way valve opens and the second one-way valve closes, allowing the disinfectant to enter the annular cavity through the first flexible tube and spray onto the tagging wound on the ear through the spray nozzle. This automatic disinfection of the tagging wound is more convenient, faster, and ensures effective tagging. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 This invention provides an ear tagging device for livestock farming, including a grip plate 1. Two symmetrically arranged movable plates 11 are connected to the side wall of the grip plate 1 via a moving mechanism. Each movable plate 11 has a pressure ring 12 fixedly connected to its side wall. An L-shaped plate 14 is fixedly connected to the top of the upper movable plate 11, and a first movable block 15 is connected to the top of the L-shaped plate 14 via a power-accumulating mechanism. A mounting base 16 is fixedly connected to the bottom of the first movable block 15, and a pin 17 is detachably connected to the mounting base 16. A pressure plate 13 is fixedly connected to the side wall of the lower pressure ring 12. A disinfection mechanism for disinfecting the tagging location is provided between the two pressure rings 12. Before tagging, power is accumulated, enabling rapid puncture during tagging, reducing animal pain, and ensuring vertical tagging for better results. After tagging, disinfectant is automatically sprayed onto the tagging wound on the ear, automatically disinfecting the wound, making it more convenient and faster, and ensuring the tagging effect.

[0029] The power storage mechanism includes two symmetrically arranged movable rods 301 inserted into the top of the L-shaped plate 14. The lower ends of the movable rods 301 are fixed to the top of the first movable block 15. The upper ends of the movable rods 301 are fixedly connected to the second movable block 302. The top of the second movable block 302 is fixedly connected to two symmetrically arranged first sleeves 303. A first sleeve rod 304 is inserted into each first sleeve 303. A pressing block 306 is fixedly connected to the upper end of the first sleeve rod 304. A first spring 305 is sleeved on the side wall of each first sleeve 303. The top of the L-shaped plate 14 is provided with a first limiting mechanism for limiting the pressing block 306, and the top of the L-shaped plate 14 is provided with a second limiting mechanism for limiting the first moving block 15. When it is necessary to tag the livestock with ear tags, the pressing block 306 is pressed down first. At this time, the first moving block 15 is limited by the second limiting mechanism. At this time, the moving rod 301 will not move down, so that the first spring 305 is gradually compressed to store force. At the same time, the pressing block 306 is limited by the first limiting mechanism.

[0030] The first limiting mechanism includes a mounting block 601 fixedly connected to the top of the L-shaped plate 14, and a mounting cover 602 fixedly connected to the top of the mounting block 601. A sliding plate 603 is connected inside the mounting cover 602 via a telescopic mechanism, and multiple arrayed limiting blocks 604 are fixedly connected to the side wall of the sliding plate 603. The top of the limiting block 604 is provided with an inclined surface 605. The movement of the sliding plate 603 is driven by a pushing mechanism. When the pressing block 306 moves downward, it can slide downward along the inclined surface 605. At the same time, it pushes the limiting block 604 to retract into the mounting cover 602, and the second spring 703 is compressed. When the pressing block 306 passes the limiting block 604, the top of the pressing block 306 can abut against the bottom of the limiting block 604, thereby limiting the pressing block 306 and preventing it from moving upward and resetting.

[0031] The telescopic mechanism includes two symmetrically arranged second sleeves 701 fixedly connected to the inner side wall of the mounting cover 602, and a second sleeve rod 702 is inserted into the second sleeve 701. The other end of the second sleeve rod 702 is fixed to the side wall of the sliding plate 603, and a second spring 703 is sleeved on the side wall of each second sleeve 701, which guides and resets the movement of the sliding plate 603.

[0032] The second limiting mechanism includes a limiting hole 401 opened on the side wall of the first moving block 15, and a limiting rod 402 is connected to the side wall of the L-shaped plate 14 through a reset mechanism. One end of the limiting rod 402 can be inserted into the limiting hole 401, and the other end of the limiting rod 402 is fixedly connected to a toggle plate 403. Since the limiting rod 402 is inserted into the limiting hole 401, it can limit the first moving block 15. When the toggle plate 403 is moved, the limiting rod 402 is pulled out from the limiting hole 401. At this time, the first moving block 15 is no longer limited.

[0033] The reset mechanism includes a fixing ring 501 fixedly sleeved on the side wall of the limiting rod 402. A third spring 502 is sleeved on the side wall of the limiting rod 402, and the two ends of the third spring 502 are fixed to the fixing ring 501 and the side wall of the L-shaped plate 14 respectively, which plays a guiding and reset role for the movement of the limiting rod 402.

[0034] The disinfection mechanism includes an annular cavity 901 located at the end of the pressure ring 12, and an annular plate 902 is fixedly connected to the top of the annular cavity 901. The top of the annular plate 902 has multiple arrayed spray holes 903, and the grip plate 1 is provided with a liquid supply mechanism for supplying disinfectant into the annular cavity 901. After marking is completed, the squeezing block 203 is released, and the two moving plates 11 can move away from each other under the action of the fourth spring 202. At the same time, the two pressure rings 12 are moved away from each other and detached from the ear. Furthermore, the L-shaped plate 14 can drive the ejector pin 17 to move away from the pressure plate 13 and detach from the ear, which can reduce the animal's pain and make the marking effect better. Meanwhile, disinfectant is supplied into the annular cavity 901 through the liquid supply mechanism and sprayed onto the marking wound on the ear through the spray holes 903, which can automatically disinfect the marking wound, making it more convenient and faster, and ensuring the marking effect.

[0035] The liquid supply mechanism includes a working box 1001 fixedly connected to the grip plate 1, and a sliding block 1002 slidably connected inside the working box 1001. An L-shaped block 1003 is fixedly connected to the top of the sliding block 1002, and the upper end of the L-shaped block 1003 passes through the top of the working box 1001 and is fixed to the moving plate 11. An annular cavity 901 communicates with the top of the working box 1001 through a first hose 1006. A liquid storage tank 1004 is fixedly connected to the grip plate 1, and the liquid storage tank 1004 is connected to the working box 1001 through a second hose 1005. The top of 01 is connected, and a first one-way valve is provided in the first hose 1006. The conduction direction of the first one-way valve is from the working box 1001 to the annular cavity 901, and a second one-way valve is provided in the second hose 1005. The conduction direction of the second one-way valve is from the storage tank 1004 to the working box 1001. When marking, when the two extrusion blocks 203 move closer to each other, they can drive the sliding block 1002 to move downward through the L-shaped block 1003. At this time, the square area above the sliding block 1002 in the working box 1001 is located inside the working box 1001. A negative pressure is created, and simultaneously, the first one-way valve closes and the second one-way valve opens, allowing the disinfectant stored in the storage tank 1004 to enter the working chamber 1001 through the second hose 1005. After marking is completed, the squeezing block 203 is released, and the two moving plates 11 can move away from each other under the action of the fourth spring 202. At the same time, this causes the two pressure rings 12 to move away from each other and detach from the ear. Furthermore, the L-shaped plate 14 can drive the ejector pin 17 to move away from the pressure plate 13 and detach from the ear, which can reduce the weight of livestock. The pain makes the marking effect better. At the same time, the sliding block 1002 can be moved and reset by the L-shaped block 1003. At this time, the disinfectant in the working box 1001 can be squeezed. At the same time, the first one-way valve opens and the second one-way valve closes, so that the disinfectant in the working box 1001 can enter the annular cavity 901 through the first hose 1006 and be sprayed on the marking wound on the ear through the spray hole 903. It can automatically disinfect the marking wound, which is more convenient and faster, and ensures the marking effect.

[0036] The moving mechanism includes two symmetrically arranged T-shaped guide rods 201 inserted into the side walls of each moving plate 11. The T-shaped guide rods 201 are fixed to the gripping plate 1, and a fourth spring 202 is sleeved on the side wall of each T-shaped guide rod 201. A pressing block 203 is fixedly connected to the side wall of the moving plate 11, which plays a guiding and resetting role in the movement of the moving plate 11.

[0037] The pushing mechanism includes a strip-shaped opening 801 on the top of the mounting cover 602. A pushing block 802 is slidably connected inside the strip-shaped opening 801, and the pushing block 802 is fixed to the top of the sliding plate 603. After marking is completed, the pushing block 802 is pushed to slide inside the strip-shaped opening 801, causing the sliding plate 603 to move. The second spring 703 is compressed, thereby moving the limiting block 604 into the strip-shaped opening 801 and disengaging it from the pressing block 306. At this time, the pressing block 306 is no longer limited. Then, the pressing block 306 is pulled upward to reset, and the mounting base 16 and the ejector pin 17 are driven upward to reset via the moving rod 301 and the first moving block 15.

[0038] Working principle: When using this device, to tag livestock with ear tags, first press the pressing block 306 downwards. At this time, since the limiting rod 402 is inserted into the limiting hole 401, it can limit the first moving block 15. The moving rod 301 will not move downwards, so the first spring 305 is gradually compressed to store force. At the same time, when the pressing block 306 moves downwards, it can slide down along the inclined surface 605, pushing the limiting block 604 into the mounting cover 602. The second spring 703 is compressed. When the pressing block 306 passes the limiting block 604, the top of the pressing block 306 can abut against the bottom of the limiting block 604, thereby limiting the pressing block 306 and preventing it from moving upwards to reset.

[0039] Next, clamp the auxiliary label onto the pressure plate 13, and place the main label onto the ejector pin 17. Then, hold the grip plate 1 and press the two compression blocks 203 closer together. At the same time, the moving plate 11 drives the two pressure rings 12 to move closer together, and the fourth spring 202 is gradually compressed. When the pressure ring 12 comes into contact with the animal's ear, it clamps and limits the position, which can achieve the positioning effect and ensure that the marking position is more accurate. Next, move the actuating plate 403 so that the limiting rod 402 is pulled out from the limiting hole 401. At the same time, the third spring 502 is stretched. At this time, the first moving block 15 is no longer limited, and the second moving block 302 can move downward quickly under the action of the first spring 305. At the same time, the moving rod 301 and the first moving block 15 drive the ejector pin 17 and the main label to move downward quickly and insert into the auxiliary label after passing through the ear, realizing a quick marking operation, which is more convenient and faster, can reduce the animal's pain, and can ensure vertical marking, making the marking effect better.

[0040] During marking, when the two extrusion blocks 203 move closer to each other, the sliding block 1002 can be moved downward by the L-shaped block 1003. At this time, a negative pressure is formed in the working box 1001 above the sliding block 1002. At the same time, the first one-way valve is closed and the second one-way valve is opened, so that the disinfectant stored in the liquid storage tank 1004 can enter the working box 1001 through the second hose 1005.

[0041] After marking is completed, the squeezing block 203 is released, and the two moving plates 11 can move away from each other under the action of the fourth spring 202. At the same time, the two pressure rings 12 are moved away from each other and detached from the ear. Furthermore, the L-shaped plate 14 can drive the ejector pin 17 to move away from the pressure plate 13 and detach from the ear, which can reduce the animal's pain and make the marking effect better. Meanwhile, the L-shaped block 1003 can drive the sliding block 1002 to move and reset. At this time, the disinfectant in the working box 1001 can be squeezed. At the same time, the first one-way valve opens and the second one-way valve closes, so that the disinfectant in the working box 1001 can enter the annular cavity 901 through the first hose 1006 and be sprayed on the marking wound on the ear through the spray hole 903. This can automatically disinfect the marking wound, making it more convenient and faster, and ensuring the marking effect.
