Description

Technical Field

[0001] This utility model provides a cow neck clip, and particularly relates to a detachable and multifunctional cow neck clip. Background Technology

[0002] A cattle neck clamp is a livestock device used to restrict the movement of cattle, primarily in large-scale farms. It controls the cattle's behavior, such as feeding and medical procedures, by fixing their necks. Traditional cattle neck clamps typically consist of a fixed support frame and a movable neck yoke. Their function is to prevent cattle from moving freely while feeding, improving feed utilization; and to restrict the cattle's movement during medical procedures such as vaccinations and disease treatments, ensuring the safety of the personnel.

[0003] The existing basic structure of a cattle neck clamp includes a fixed base welded to the fence and a neck yoke hinged to the base. The neck yoke is opened and closed by a spring or a buckle. However, this structure has the following shortcomings:

[0004] Installation is inconvenient: Bolts are required to weld or fix the base to the fence, and installation and disassembly are time-consuming and labor-intensive, making it impossible to quickly adjust the position or replace the equipment.

[0005] Limited functionality: It can only achieve simple fixation when cattle are eating, and cannot be flexibly adjusted according to different scenarios (such as medical operations). The range of motion and locking method of the neck yoke lack adaptability.

[0006] Low structural strength: Traditional welding or hinged joints are prone to loosening or breakage after long-term use, especially when cattle struggle, the joints are easily damaged, affecting the service life.

[0007] Poor comfort: The neck yoke is in direct contact with the cow's neck and lacks a cushioning structure, which can easily cause abrasions or pressure on the cow, failing to meet animal welfare requirements.

[0008] Adjustment difficulties: Existing devices are difficult to adjust precisely according to the size of cattle, and have poor applicability to cattle at different growth stages or breeds. Utility Model Content

[0009] In order to solve the above problems, this application provides a detachable multi-functional cow neck clamp, which solves the problems of cumbersome installation, limited function, inconvenient adjustment, insufficient structural strength and poor adaptability of existing devices.

[0010] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a detachable and multifunctional cow neck clamp, including a fence, on which a cow neck yoke structure is connected by a snap-fit ​​structure; the cow neck yoke structure includes a base and a neck yoke bar;

[0011] The locking structure is movably disposed within the base. The base has a connector that passes through itself and is welded to the neck yoke on the side away from the locking structure. The connector is connected to an arc-shaped limiting plate corresponding to itself via a protrusion. An adjusting rod is fixedly connected to the other side of the limiting plate, and an adjusting component is sleeved on the other end of the adjusting rod.

[0012] Preferably, the connector includes a connecting rod corresponding to the protrusion, and one end of the connecting rod near the neck yoke is integrally connected to a welded component that is welded to the neck yoke.

[0013] Preferably, the adjusting component includes a rod portion placed inside the base, and an auxiliary handle placed outside the base is fixedly connected to one end of the rod portion away from the adjusting rod.

[0014] Preferably, a fixed plate is fixedly connected to the adjusting rod, and a movable plate is movably sleeved on the side of the fixed plate away from the limiting plate outside the adjusting rod. A return spring is provided between the movable plate and the fixed plate, and is sleeved on the outside of the adjusting rod. The adjusting component is placed on the side of the movable plate away from the fixed plate.

[0015] Preferably, the base has an internal fitting groove corresponding to the bull neck yoke structure, and the other side of the fitting groove has an arc-shaped rotating groove that is connected to itself and corresponds to the rod part of the adjusting member.

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0017] In use, this device utilizes a snap-fit ​​mechanism to quickly engage with the fence, enabling rapid installation of the cow neck yoke. When the cow lies down, the lower end of the neck yoke bar is pressed outwards, causing the arc-shaped section above the yoke bar to engage above the cow's neck, thus fixing the cow's position. This is suitable for use when the cow is eating. When the cow finishes eating and wants to leave, raising its head will reset the neck yoke bar. Furthermore, during rotation, the neck yoke bar causes the protrusion to rotate, pressing against the position of the limiting plate. The limiting plate then moves the adjusting rod and the fixing plate, compressing the return spring. At this point, the interaction of the adjusting component in the rotating groove rotates the limiting plate, causing it to rotate around the axis of the connecting rod of the connecting component. By changing the position of the limiting plate so that it abuts against the higher end of the protrusion, the position of the neck yoke bar is fixed, suitable for fixation during cow treatment.

[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figure 1 and Figure 2As shown, a detachable multi-functional cow neck clamp includes a fence 1. A cow neck yoke structure 2 is connected to the fence 1 via a locking structure 11. The cow neck yoke structure 2 includes a base 21 and a neck yoke bar 22. The locking structure 11 is movably disposed within the base 21. A connector 23 is provided on the side of the base 21 away from the locking structure 11, penetrating through itself and welded to the neck yoke bar 22. A corresponding arc-shaped limiting plate 25 is connected to the connector 23 via a protrusion 24. An adjusting rod 26 is fixedly connected to the other side of the limiting plate 25. An adjusting component 27 is sleeved and connected to the other end of the adjusting rod 26. The connector 23 includes a connecting rod corresponding to the protrusion 24. A welding component 28 is integrally connected to the end of the connecting rod near the neck yoke bar 22 and welded to the neck yoke bar 22.

[0030] In this embodiment, the locking structure 11 and the fence 1 are connected by a movable locking mechanism, specifically using a combination of a slot and a block. The block is fixed to the fence 1, and the slot is formed on the locking structure 11. The two are interference-fitted to achieve a detachable connection. The locking structure 11 can slide horizontally within the base 21 with a sliding stroke of 5-10mm to accommodate installation errors of different fence models. The base 21 has a cuboid structure with an internal groove adapted to the locking structure 11. The groove is 20mm deep and 15mm wide to ensure smooth sliding of the locking structure 11 and prevent it from falling off. The connecting rod of the connector 23 has a diameter of 12mm and a length of 80mm. Its integrated connection with the welded part 28 is achieved by forging. The welded part 28 has a U-shaped structure and is welded to the neck yoke 22 using carbon dioxide gas shielded welding. The weld height is 4mm to ensure connection strength. The protrusion 24 is hemispherical with a diameter of 10mm. It is bolted to the limiting plate 25 with an M6×15 bolt, ensuring that the limiting plate 25 can rotate around the center of the protrusion 24 with a rotation angle range of 0-45°. The adjusting rod 26 has a diameter of 8mm and a length of 150mm. It is welded to the limiting plate 25 with a double-sided fillet weld and a weld height of 3mm. The rod part of the adjusting component 27 has a diameter of 10mm and a length of 60mm. It is threaded to the auxiliary handle 3 with an M10×1.5 thread. The auxiliary handle 3 is cylindrical with a diameter of 30mm and a length of 80mm. Its surface has anti-slip texture and a friction coefficient ≥0.6.

[0031] The roles and benefits of each structure in solving existing technical problems are as follows:

[0032] The snap-fit ​​structure 11, with its movable design within the base 21, allows for tool-free installation of the bull neck yoke structure 2 and the fence 1, enabling manual snap-fitting and disassembly. This reduces installation time from 5 minutes for traditional bolted connections to 30 seconds, significantly improving work efficiency. Furthermore, the movable connection method compensates for manufacturing errors in the fence 1, broadening its applicability to fences of varying thicknesses from 3 to 5 mm.

[0033] The combination of connector 23 and welded part 28: The connecting rod of connector 23 serves as the rotation axis, allowing the neck yoke 22 to rotate flexibly around it with a rotation torque of 5-8 N·m, ensuring that the neck yoke 22 responds sensitively when the cow lies down and raises its head. The U-shaped structure of welded part 28 increases the welding area with the neck yoke 22, improving the welding strength by 30% compared to traditional flat welding. Tests show that the weld can withstand a tensile force of 1000 N without damage.

[0034] The linkage between the limiting plate 25 and the adjusting rod 26: When the neck yoke 22 rotates, the protrusion 24 pushes the limiting plate 25. The limiting plate 25, through the adjusting rod 26, drives the fixing plate 31 to compress the return spring 33. The spring constant of the return spring 33 is 20 N / mm, the maximum compression is 30 mm, and it can provide a return force of 600 N, ensuring that the neck yoke 22 can quickly return to its original position after the cow raises its head. At the same time, the arc-shaped design of the limiting plate 25 and the hemispherical shape of the protrusion 24 make the rotation process smooth and easy, reduce the wear rate by 50%, and extend the service life to more than 5 years.

[0035] The adjustment component 27 and the rotating groove 35 are designed to rotate within the groove 35 at an angle range of 0-45°, corresponding to a position adjustment of 0-20mm for the limiting plate 25. This allows for precise adjustment based on the size of the cow. The anti-slip design of the auxiliary handle 3 allows the operator to complete the adjustment with a force of only 50N, reducing the operating force by 40% compared to traditional knob-type adjustments. After adjustment, the limiting plate 25 engages with the protrusion 24 to achieve self-locking, with a locking force ≥300N, ensuring that the handle will not loosen during the cow's struggle.

[0036] The return spring 33 is sleeved on the outside of the adjusting rod 26. The initial distance between the movable plate 32 and the fixed plate 31 is 15mm. When the neck yoke 22 rotates to its maximum angle, the distance is compressed to 5mm, and the spring stores 30J of energy. After the cow raises its head to release the constraint, the spring releases energy, causing the neck yoke 22 to return to its original position within 0.5 seconds. The return time is shortened by 70% compared to the springless structure, improving ease of use.

[0037] like Figure 3 , 4As shown in Figure 5, an adjustable component 27 of a detachable multi-functional cow neck clamp includes a rod portion placed inside a base 21. An auxiliary handle 3 is fixedly connected to the end of the rod portion away from the adjusting rod 26, which is placed outside the base 21. A fixing plate 31 is fixedly connected to the adjusting rod 26. A movable plate 32 is movably sleeved outside the adjusting rod 26 on the side of the fixing plate 31 away from the limiting plate 25. A return spring 33 is provided between the movable plate 32 and the fixing plate 31, which is sleeved outside the adjusting rod 26. The adjustable component 27 is placed on the side of the movable plate 32 away from the fixing plate 31. The interior of the base 21 is provided with a fitting groove 34 corresponding to the cow neck clamp structure 2. The other side of the fitting groove 34 is provided with an arc-shaped rotating groove 35 that communicates with itself and corresponds to the rod portion of the adjustable component 27.

[0038] In this implementation plan:

[0039] I. The Feeding Process of Cattle

[0040] Initial state: The engaging structure 11 engages quickly with the locking block on the fence 1 through the locking slot, the cow neck yoke structure 2 is in a free state, the neck yoke bar 22 is perpendicular to the ground, the return spring 33 is in a naturally extended state, and the contact point between the limiting plate 25 and the protrusion 24 is located at the lower position of the protrusion.

[0041] When the cow lies down to eat, its shoulders press against the lower end of the neck yoke 22, causing it to rotate outward (clockwise) around the connecting rod axis of the connector 23, with a rotation angle of approximately 15°-20°. At the same time, the arc-shaped section above the neck yoke 22 rotates inward (counterclockwise) simultaneously, engaging above the cow's neck. The contact pressure between the arc-shaped section and the cow's neck is approximately 20-30N, achieving temporary fixation of the cow.

[0042] When the cow finishes eating and raises its head, it pushes the curved section of the neck yoke 22 upwards, causing it to rotate inwards (counterclockwise) around the axis of the connecting rod to return to its original position. The return spring 33 releases its elastic potential energy, which drives the neck yoke 22 to quickly return to its original position through the fixing plate 31, adjusting rod 26, and limiting plate 25. The return time is ≤0.5 seconds. After returning to its original position, the neck yoke 22 returns to the vertical position, ready for the next use.

[0043] II. The Fixed-State Operation Process of Cattle Medical Care

[0044] Neck lever rotation: When medical procedures are required on cattle, the neck lever 22 is rotated outward (clockwise) around the axis of the connecting rod to its maximum angle (approximately 30°-45°) by external force (such as manual pushing by the feeder). At this time, the protrusion 24 rotates synchronously with the neck lever 22, and its hemispherical surface presses against the arc-shaped inner surface of the limiting plate 25, pushing the limiting plate 25 to move axially along the adjusting rod 26.

[0045] Spring compression: The movement of the limiting plate 25 causes the adjusting rod 26 and the fixed plate 31 to move synchronously, compressing the return spring 33. When the neck yoke 22 rotates to its maximum angle, the return spring 33 is compressed to 20-25mm, storing approximately 25-30J of elastic potential energy, and the axial force provided by the spring is approximately 500-600N.

[0046] Limit plate rotation locking: The operator holds the auxiliary handle 3 and rotates the adjusting component 27 clockwise along the rotating groove 35 by about 20°-30°, causing the limit plate 25 to rotate synchronously around the axis of the connecting rod. After the limit plate 25 rotates, its contact point with the protrusion 24 moves from the lower position of the protrusion to the higher position of the protrusion, and the radial distance at the contact point increases by 5-8mm, thus achieving mechanical locking of the neck yoke 22. At this time, the neck yoke 22 is fixed at the maximum rotation angle position and can withstand the lateral pulling force ≥300N generated by the cow's struggle.

[0047] Release: After the medical procedure is completed, the operator holds the auxiliary handle 3 and rotates the adjusting component 27 counterclockwise to the initial position. The contact point between the limiting plate 25 and the protrusion 24 returns to the lower protrusion position. The return spring 33 releases its elastic potential energy, pushing the fixing plate 31, adjusting rod 26, and limiting plate 25 to move in the opposite direction, causing the neck yoke 22 to return to the vertical position, thus releasing the cattle from the restraints.

[0048] Specifically, it is necessary to combine existing technologies such as cattle feeders and neck yoke buffer sleeves to achieve more complete functionality. The cattle feeder is made of stainless steel (model SUS304), with a wall thickness of 2mm, a depth of 150mm, and a trough width of 300mm. It is fixed to the ground in front of the fence 1 using expansion bolts (M10×80). The bottom of the feeder has drainage holes (φ10mm) spaced 200mm apart to effectively prevent feed from accumulating water and becoming moldy. The neck yoke buffer sleeve is made of EPDM rubber with a Shore A hardness of 60A, an inner diameter of 25mm, a wall thickness of 5mm, and a length of 300mm. It is fitted onto the outer surface of the arc-shaped section of the neck yoke 22. Its surface has diamond-shaped anti-slip textures (1mm deep, 5mm spaced) to increase the friction with the cattle's neck to 0.8μ, while preventing the neck yoke 22 from causing abrasions to the cattle's neck. Furthermore, the inner surface of the slot of the locking structure 11 is inlaid with nylon wear-resistant sheets (2mm thick, model PA66+GF30), which can reduce the sliding friction coefficient between the locking block and the slot to 0.15, reducing wear and extending the service life to 100,000 opening and closing cycles. The auxiliary handle 3 of the adjusting component 27 is inlaid with a magnet (model N35), which forms a magnetic fixation with the iron sheet (1.5mm thick) on the surface of the base 21, with a magnetic force ≥5N, which can prevent the adjusting component 27 from rotating accidentally. The inner surfaces of the locking groove 34 and the rotating groove 35 of the base 21 are galvanized (coating thickness 8μm), and do not rust after ≥96 hours of salt spray testing, making them suitable for humid breeding environments. The entire cattle neck yoke structure 2 is made of Q235B steel, and the surface is shot blasted and then electrostatically powder coated with a coating thickness of 80μm, a gloss of 60±5GU, and an impact resistance of ≥50kg·cm, which can effectively resist cattle impacts and daily wear.

[0049] When using:

[0050] I. Usage and Process During Cattle Feeding

[0051] Usage: Suitable for cattle when they are eating feed. The purpose is to temporarily fix the cattle's position, prevent them from moving around randomly, and ensure a stable feeding process.

[0052] Usage process: First, use the snap-fit ​​mechanism to quickly snap the cow neck yoke structure to the fence to complete the installation; when the cow lies down to eat, its movement will push the lower end of the neck yoke bar outward, so that the arc-shaped section of the neck yoke bar will naturally snap into place above the cow's neck, thus fixing the position; when the cow finishes eating and wants to leave, the head-raising movement will cause the neck yoke bar to return to its original position, releasing the fixed state.

[0053] II. Usage and Process in Cattle Treatment

[0054] Usage: Applicable to the medical treatment of cattle, where the cattle need to be stably restrained to prevent them from struggling and interfering with the medical procedure.

[0055] Usage: After basic installation is completed, when the cow moves due to medical procedures, causing the neck yoke to rotate, the neck yoke will drive the protrusion to rotate, thereby squeezing the limiting plate. After the limiting plate is subjected to force, it will drive the adjusting rod and the fixing plate to move, causing the return spring to compress. At this time, by operating the adjusting component in the rotating groove, the limiting plate can be rotated around the connecting rod axis of the connecting component as the center. Adjusting the position of the limiting plate so that it abuts against the higher end of the protrusion, thereby fixing the position of the neck yoke, achieving stable restraint on the cow, and ensuring the smooth progress of medical procedures.
