Description

Technical Field

[0001] This invention relates to the field of livestock breeding equipment technology, and in particular to a cow ear marking device with antibacterial function. Background Technology

[0002] In large-scale livestock farming, individual cattle identification is a fundamental step in disease prevention and control, traceability management, and production record keeping. Ear tags, as the core tool for attaching ear tags, are mechanically punctured to secure the tag to the cow's ear, thus identifying it. However, the puncture operation requires penetrating the ear skin, creating an open wound. If the tag surface carries pathogenic microorganisms, it can easily lead to localized infections or even the spread of disease in the flock, seriously threatening animal health and farming efficiency.

[0003] Currently, most commercially available cattle ear marking devices are purely mechanical, consisting of a handle, jaws, and firing mechanism, primarily made of stainless steel or engineering plastics. While some products improve surface smoothness to reduce dirt adhesion, they lack active disinfection capabilities. During continuous operation, operators typically rely on manual wiping or soaking to disinfect the equipment, which is not only inefficient but also makes thorough cleaning before and after each use difficult, posing a significant risk of cross-infection. To address these issues, existing research attempts to introduce ultraviolet or ozone disinfection modules into livestock equipment; however, these solutions are complex, costly, and require external power, making them unsuitable for field or mobile farming environments. Another common method is the use of chemical disinfectants (such as alcohol and iodine), which, while reliable and rapid, require manual spraying or application, making standardized execution difficult in fast-paced marking operations. This results in low actual disinfection coverage and poor timeliness, failing to meet the "one cow, one disinfection" requirement for disease prevention.

[0004] In summary, there is an urgent need for a compact, easy-to-operate bull's ear marking device that does not require external power and can automatically trigger a disinfection program after marking, so as to accurately disinfect the puncture site and the contact surface of the forceps in real time, thereby filling the gap in the existing technology in real-time, automatic, and fixed-point disinfection. Summary of the Invention

[0005] In order to overcome the shortcomings of existing cow ear marking devices that lack built-in automatic disinfection functions, making it difficult to achieve efficient and timely "one cow, one disinfection" and posing a risk of cross-infection, this invention provides a cow ear marking device with antibacterial function.

[0007] More preferably, the clamping assembly includes a clamping plate rotatably connected to the lower left of the main handle, and the clamping plate is connected to the main handle by a second torsion spring, which is wound around the clamping plate; the lower left of the main handle has a U-shaped notch at the corresponding marking needle, and the clamping plate also has a corresponding U-shaped notch for the marking needle to pass through.

[0008] More preferably, in the automatic disinfection mechanism: each disinfectant reservoir is fixedly connected to the left side of the main handle and the auxiliary handle, each disinfectant reservoir has a cavity for storing disinfectant, and each has an oblique directional disinfection nozzle on its adjacent side, with each directional disinfection nozzle facing the marking needle; the disinfectant spray driving assembly includes a pneumatic drive plate that is horizontally slidably connected to the right side of each disinfectant reservoir, and each disinfectant reservoir has a symmetrically distributed reset telescopic rod fixedly connected to its outer wall, the fixed end of each reset telescopic rod being connected to the outer wall of the disinfectant reservoir, and the telescopic end being fixedly connected to the corresponding pneumatic drive plate, and the telescopic end and the fixed end of each reset telescopic rod being connected by a reset spring; each disinfectant reservoir has a drive cylinder fixedly connected to its outer wall, and each cylinder has a piston rod that is horizontally slidably connected inside, with the right end of each cylinder piston rod being fixedly connected to the corresponding pneumatic drive plate.

[0009] More preferably, each drive cylinder has an air outlet on its left wall, and each air outlet is equipped with an air outlet check valve; each drive cylinder has an air inlet on its side wall, and each air inlet is equipped with an air inlet check valve; each directional disinfection nozzle is equipped with a liquid spray check valve; both the main handle and the auxiliary handle have drive bosses on their protrusions near the hinge shaft, the drive boss on the main handle contacts the right side of the upper pneumatic drive plate, and the drive boss on the auxiliary handle contacts the right side of the lower pneumatic drive plate.

[0010] More preferably, the disinfectant gathering and squeezing assembly includes variable volume squeezing bladders fixedly attached to each disinfectant storage frame. Each variable volume squeezing bladder is a square box with its surrounding walls made of sealed corrugated pipes. The top plate and bottom wall are rigid plates, which are connected by the sealed corrugated pipes to form a sealed chamber. The air outlet of each drive cylinder is connected to the inner cavity of the corresponding variable volume squeezing bladder.

[0011] More preferably, the top plate of the upper variable volume squeezing bladder is fixed to the inner wall of the upper disinfectant reservoir and flush with the top surface, and its bottom wall and surrounding walls are movable parts; the bottom wall of the lower variable volume squeezing bladder is fixed to the inner wall of the lower disinfectant reservoir and flush with the bottom surface, and its top wall and surrounding walls are movable parts; the side of the two variable volume squeezing bladders that are close to each other is provided with a movable plate.

[0012] More preferably, each of the variable volume compression bladders has an exhaust guide tube fixedly connected to one of its opposite sides, and each exhaust guide tube has a magnetic exhaust pin slidably connected vertically inside it; each exhaust guide tube has a reset magnet fixedly connected inside it, and the magnetic exhaust pin slides vertically on the corresponding reset magnet. The two magnetically cooperate to keep each exhaust pin in a retracted state when not under pressure.

[0013] More preferably, the disinfectant depletion indicator includes a disinfectant filling chamber fixed to the left side of each disinfectant reservoir, and each disinfectant filling chamber has a vertical channel communicating with the inner cavity of the corresponding disinfectant reservoir. Each disinfectant filling chamber is rotatably connected to a self-opening filling cap, which is connected to the disinfectant filling chamber via a first torsion spring. Each first torsion spring is wound around the adjacent self-opening filling cap to provide torque that tends to open the self-opening filling cap.

[0014] More preferably, each disinfectant filling chamber is equipped with a filling cap locking assembly. This assembly includes a linkage unlocking press block that slides horizontally to the right side of each disinfectant filling chamber. It is connected to the adjacent disinfectant filling chamber by two second springs. Each opening filling cap is provided with a hook on the side near the linkage unlocking press block. Each linkage unlocking press block is provided with a cavity for the hook to be inserted and a locking hook mating surface that cooperates with the hook.

[0015] More preferably, the linkage unlocking press block is provided with a slope on the side near the variable volume compression bladder, and each magnetic exhaust pin is spherical at the end that is far away from each other; the upper linkage unlocking press block is located to the upper left of the upper magnetic exhaust pin, and the lower linkage unlocking press block is located to the lower left of the lower magnetic exhaust pin.

[0016] The present invention has the following advantages: By linking the disinfectant storage box, the drive cylinder, the pneumatic drive plate and the handle, the present invention automatically triggers the spraying of disinfectant after the marking is completed and the handle is released, which is precisely applied to the marking needle and puncture site, realizing "one disinfection per cow"; no additional manual disinfection operation is required, avoiding cross-infection caused by continuous operation, and significantly improving the level of biosecurity in aquaculture.

[0017] This invention features a variable-volume compression bladder, the inner cavity of which is connected to a drive cylinder. It inflates and expands each time it is reset, actively squeezing the disinfectant towards the directional disinfection nozzle. Regardless of whether the marking device is held horizontally, tilted, or upside down, the disinfectant can be effectively pushed to the nozzle inlet, completely solving the problem of gravity causing the liquid surface to move away from the nozzle and ensuring stable and reliable disinfection function at all angles.

[0018] After the variable-volume compression bladder expands to its limit, the increased air pressure inside automatically pushes out the magnetic venting pin, which in turn unlocks the linkage pressing block, causing the self-opening filling cap to automatically spring open under the action of the first torsion spring. Operators can intuitively see the liquid shortage status without inspection, and after adding liquid, the compression bladder automatically contracts and resets, and the pin can be manually returned to its original position and the cap can be relocked. The structure is ingenious and easy to use. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0028] Example 1: A cow ear marking device with antibacterial function, such as... Figures 1-3 As shown, it includes a main grip 101 and a secondary grip 102, which are rotatably connected by a hinge shaft and connected by a first spring 103 to provide a restoring force when opened.

[0029] A marking pin 1031 for holding an earring is fixedly attached to the upper left part of the secondary handle 102. A clamping assembly for securing the earring is provided on the lower left part of the main handle 101. This clamping assembly includes a pressure plate 401 rotatably connected to the lower left part of the main handle 101, which is connected to the main handle 101 via a second torsion spring 402 to provide pre-tension force for clamping the earring. A U-shaped notch is provided on the lower left part of the main handle 101 at the corresponding marking pin 1031, and a corresponding U-shaped notch is also provided on the pressure plate 401 for the marking pin 1031 to pass through.

[0030] Both the main handle 101 and the auxiliary handle 102 have an automatic disinfection mechanism for disinfecting the marking needle 1031 on their left sides. This mechanism includes disinfectant reservoirs 104 fixed to the left sides of the main handle 101 and the auxiliary handle 102, respectively. Each disinfectant reservoir 104 has a cavity for storing disinfectant, and each has an angled directional disinfection nozzle 110 on one of their adjacent sides, with each directional disinfection nozzle 110 facing the marking needle 1031.

[0031] like Figure 3 and Figure 4 As shown, each disinfectant reservoir 104 has a disinfectant spraying drive assembly on its right side, including a pneumatic drive plate 105 that is horizontally slidably connected to the right side of each disinfectant reservoir 104. Each disinfectant reservoir 104 has a symmetrically distributed reset telescopic rod 106 fixedly connected to its outer wall. The fixed end of the rod is connected to the outer wall of the disinfectant reservoir 104, and the telescopic end is fixedly connected to the corresponding pneumatic drive plate 105. The telescopic end and fixed end of each reset telescopic rod 106 are connected by a reset spring (built-in, not shown) to provide a reset force. Each disinfectant reservoir 104 has a drive cylinder 112 fixedly connected to its outer wall, and a cylinder piston rod 107 is horizontally slidably connected inside each cylinder piston rod 107. The right end of each cylinder piston rod 107 is fixedly connected to the corresponding pneumatic drive plate 105.

[0032] Each drive cylinder 112 has an air outlet on its left wall, and each air outlet is equipped with an air outlet check valve 109. Each drive cylinder 112 has an air inlet on its side wall, and each air inlet is equipped with an air inlet check valve 108, used to draw air from the outside when the piston returns to its original position. Each directional disinfection nozzle 110 is equipped with a liquid spray check valve 111, used to allow disinfectant to be squeezed out when the air pressure in the disinfectant reservoir 104 increases, and to remain closed in the absence of pressure or under negative pressure to prevent self-drip.

[0033] Both the main grip 101 and the secondary grip 102 have a drive boss 113 on the protrusion near the hinge axis. The drive boss 113 on the main grip 101 contacts the right side of the upper pneumatic drive plate 105, and the drive boss 113 on the secondary grip 102 contacts the right side of the lower pneumatic drive plate 105.

[0034] Because the grip direction is not fixed during use, the disinfectant will accumulate at the lowest position of the storage frame under the influence of gravity, which may prevent the directional disinfection nozzle 110 from drawing up the disinfectant. Therefore, this marking device is also equipped with a disinfectant gathering and squeezing component.

[0035] like Figure 4 and Figure 5 As shown, the component includes variable-volume squeeze bladders 201 respectively fixedly attached to each disinfectant reservoir 104. The top plate of the upper variable-volume squeeze bladder 201 is fixedly attached to the inner wall of the upper disinfectant reservoir 104 and flush with the top surface, and its bottom wall and surrounding walls are movable parts; the bottom wall of the lower variable-volume squeeze bladder 201 is fixedly attached to the inner wall of the lower disinfectant reservoir 104 and flush with the bottom surface, and its top wall and surrounding walls are movable parts; the sides of the two variable-volume squeeze bladders 201 that are close to each other are provided with movable plates.

[0036] Each variable volume compression bladder 201 is a square box, with all four sides made of sealed bellows 202. The top plate and bottom wall are rigid plates, which are connected by the sealed bellows 202 to form a sealed chamber.

[0037] Each drive cylinder 112 has an air outlet that is connected to the inner cavity of the corresponding variable volume compression bladder 201, allowing compressed gas to enter the compression bladder and expand it, thereby squeezing the disinfectant liquid to flow towards the directional disinfection nozzle 110.

[0038] Each of the variable-volume compression bladders 201 has an exhaust guide tube 203 fixedly connected to one of its opposite sides, and each tube has a magnetically attached exhaust pin 204 that slides vertically inside it. Each exhaust guide tube 203 has a reset magnet 205 fixedly connected inside it, and the magnetically attached exhaust pin 204 slides vertically on the corresponding reset magnet 205. The two magnetically engage, so that each exhaust pin remains in a retracted state when not under pressure.

[0039] Each disinfectant storage container 104 is equipped with a disinfectant depletion indicator on its left side, such as... Figure 6 and Figure 7 As shown, the disinfectant depletion warning mechanism includes disinfectant filling chambers 301 fixed to the left side of each disinfectant storage frame 104, each with a vertical channel communicating with the inner cavity of the corresponding disinfectant storage frame 104. Each disinfectant filling chamber 301 is rotatably connected to a self-opening filling cap 302, which is connected to the filling chamber via a first torsion spring 303. Each first torsion spring 303 provides torque to open the filling cap.

[0040] Each disinfectant dispensing compartment 301 is equipped with a dispensing cap locking assembly, including a linkage unlocking press block 304 that slides horizontally to the right side of the dispensing compartment. Each of these blocks is connected to the adjacent disinfectant dispensing compartment 301 via two second springs 305. Each self-opening dispensing cap 302 has a hook on the side near the linkage unlocking press block 304. Each linkage unlocking press block 304 has a cavity for the hook to insert into and a locking hook mating surface 306 that engages with the hook. Through the engagement of the hook and the locking hook mating surface 306, each linkage unlocking press block 304 can lock the corresponding self-opening dispensing cap 302.

[0041] The linkage unlocking press block 304 has a bevel on the side near the variable volume compression bladder 201. Each magnetic exhaust pin 204 has a spherical surface at the end that is far away from each other. The upper linkage unlocking press block 304 is located to the upper left of the upper magnetic exhaust pin 204, and the lower linkage unlocking press block 304 is located to the lower left of the lower magnetic exhaust pin 204.

[0042] Working principle: Before first use, manually press the linkage unlocking press block 304 to the left to compress the second spring 305, causing it to release the hook lock on the self-opening filling cap 302. The self-opening filling cap 302 automatically flips open under the elastic force of the first torsion spring 303. Disinfectant is injected into the disinfectant storage frame 104 through the vertical channel of the disinfectant filling chamber 301 until the liquid surface contacts the movable plate of the variable volume squeezing bladder 201. Then, the self-opening filling cap 302 is closed in the reverse direction. Its hook pushes the linkage unlocking press block 304 to the left, and after passing the top surface, the second spring 305 pushes it to the right to reset. The locking hook mating surface 306 re-hooks the self-opening filling cap 302, completing the seal.

[0043] Pry the clamping plate 401 upwards to charge the second torsion spring 402. Place the perforated part of the earring at the U-shaped notch on the left side of the main handle 101. Release the clamping plate 401, and the second torsion spring 402 will drive the clamping plate 401 to reset and clamp the earring. Place the earring on the marking pin 1031 on the left side of the secondary handle 102.

[0044] Hold the handles of the main handle 101 and the secondary handle 102, so that the left forks are engaged with the two sides of the bull's ear (the earring and the ear tag are located on the two sides of the bull's ear). Grip the two handles tightly, the first spring 103 is compressed, the left sides of the main handle 101 and the secondary handle 102 move closer together, the marking pin 1031 pierces the bull's ear and drives the earring through the ear tag, completing the marking.

[0045] At the same time, the drive boss 113 gradually releases its pressure on the pneumatic drive plate 105, the return spring in the return telescopic rod 106 extends, pushing the pneumatic drive plate 105 to the right, causing the cylinder piston rod 107 to move to the right, creating negative pressure in the drive cylinder 112, and opening the air intake one-way valve 108 to draw in air. During this stage, there is no increase in air pressure in the disinfectant storage box 104, and no disinfectant is sprayed.

[0046] After marking is completed, the handle is released, and the first spring 103 causes the main handle 101 and the secondary handle 102 to return to their original positions. The drive boss 113 then presses against the pneumatic drive plate 105 again, pushing it to the left, and the return telescopic rod 106 is compressed. The pneumatic drive plate 105 drives the cylinder piston rod 107 to move to the left, compressing the air in the drive cylinder 112. The exhaust check valve 109 opens, and the compressed air enters the variable volume compression bladder 201 through the exhaust port. The variable volume compression bladder 201 expands, squeezing the disinfectant and increasing the pressure in the disinfectant reservoir 104. This opens the spray check valve 111, and the disinfectant is sprayed from the directional disinfection nozzle 110, precisely acting on the marking needle 1031, achieving "one cow, one disinfection".

[0047] As the number of markings increases, gas is continuously forced into the variable-volume compression bladder 201. When it expands to its limit (the movable plate contacts the inner wall of the storage frame), the continued injection of gas significantly increases the gas pressure inside the bladder. When the gas pressure is sufficient to overcome the magnetic attraction of the reset magnet 205, the magnetic venting pin 204 is pushed outward, opening the venting guide pipe 203 and allowing the variable-volume compression bladder 201 to communicate with the atmosphere. Simultaneously, the spherical end of the extended magnetic venting pin 204 presses against the inclined surface of the linkage unlocking press block 304, pushing it to the left and releasing the hook lock on the self-opening filling cap 302. The self-opening filling cap 302 automatically flips open, indicating that the disinfectant has been exhausted.

[0048] When adding disinfectant, the injected disinfectant level pushes against the movable plate of the variable volume compression bladder 201, causing it to contract and return to its original position. After adding the disinfectant, manually push the magnetic venting pin 204 back to its original position, then close the self-opening filling cap 302. The linkage unlocking press block 304 automatically hooks the filling cap, and the system returns to standby mode.

[0049] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
