Technical Field
[0001] This utility model belongs to the technical field of livestock breeding equipment, specifically relating to a fixed restraint device for facilitating the injection of vaccines into breeding cattle. Background Technology
[0002] In livestock farming, vaccination is a crucial step in preventing animal diseases. However, due to the large size, strength, and susceptibility to fright of breeding cattle, the vaccination process presents challenges in terms of operational difficulty and poses significant safety risks to personnel.
[0003] Currently, common methods of restraining cattle mainly rely on traditional restraint pens or manual binding. Traditional restraint pens are mostly fixed structures, such as concrete or welded metal enclosures, which have low flexibility and make it difficult to adjust the movement space according to the size of the breeding cattle. This can easily result in the restraint being too loose or too tight, affecting the restraint effect. Manual binding relies on ropes or belts to tie the cattle's limbs, requiring multiple people to work together, which is time-consuming, labor-intensive, and lacks stability. Furthermore, forced binding can easily cause excessive stress to the breeding cattle and may even lead to external injuries. Therefore, there is a need for a restraint device that facilitates vaccination of breeding cattle, improving operational convenience and safety, and meeting the actual needs of the livestock industry. Summary of the Invention
[0004] To overcome the shortcomings of traditional restraint pens and manual binding methods in the prior art, such as insufficient flexibility, complex operation, and poor safety, this utility model provides a restraint device for easy vaccination of breeding cattle. Through the combined use of a limiting mechanism and an adjusting mechanism, the limiting range can be flexibly adjusted according to the size of the breeding cattle, achieving multi-directional restraint of the abdomen, back, and neck. This avoids poor restraint or animal stress caused by excessively loose or tight restraints. Spatial adjustment is achieved through a mechanical transmission structure, reducing human intervention and significantly improving the safety and efficiency of the breeding cattle restraint process.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: The fixing and restraining device for facilitating the injection of vaccines into breeding cattle mainly includes a support base, a limiting mechanism, a protective railing, and an adjustment mechanism. The protective railing is welded to the outside of the support base, forming a semi-enclosed area with openings at the front and back. The limiting mechanism is slidably installed on the support base to limit the breeding cattle around its perimeter. The adjustment mechanism is installed at the bottom of the support base and connected to the limiting mechanism to drive the limiting mechanism to move horizontally along the support base to accommodate breeding cattle of different sizes.
[0006] The limiting mechanism includes a scissor bracket, a first limiting rod, a second limiting rod, a push rod, a limiting plate, a support rod, and an arc-shaped limiting groove. The scissor bracket consists of two cross-hinged connecting rods. The front and rear ends of the support base have guide grooves along the width direction, and two parallel push rods are slidably connected in the guide grooves. The bottom end of the scissor bracket passes through a rectangular through groove on the upper surface of the support base and is connected to the end of the push rod. The top ends of the scissor bracket are longitudinally connected to a first limiting rod for limiting the sides of the bull's abdomen. The top end of the scissor bracket is provided with an upwardly inclined support rod. The top ends of the support rods are longitudinally connected to a second limiting rod for limiting the bull's back. The bottom end of the limiting plate is connected to the connecting rod of the scissor bracket, and the top end is connected to the support rod and is located at the front end of the support base. The end face of the limiting plate has an arc-shaped limiting groove for limiting the bull's neck.
[0007] The adjustment mechanism includes a bidirectional lead screw, a slider, and a handwheel. The end of the bidirectional lead screw is mounted on the bottom of the support base via a bearing. The axis of the bidirectional lead screw is perpendicular to the axis of the push rod. One end of the lead screw passes through the side wall of the support base and is connected to the handwheel. The slider is mounted in the middle of the push rod and is threadedly connected to the bidirectional lead screw.
[0008] The scissor brackets are connected by two connecting rods parallel to the first limiting rod. Multiple threaded holes are equidistantly opened on the connecting rods along the axial direction. Two sets of limiting rods are threaded to the ends of the connecting rods, and the ends of the limiting rods extend along the outside of the support base.
[0009] The support base has inclined support plates on both the front and rear sides to facilitate the entry and exit of breeding cattle. The support plates are evenly provided with anti-slip ridges. The support plates are fixed to the support base by welding, and their inclination angle is 15°.
[0010] The surfaces of the first limiting rod, the second limiting rod, the limiting bar, and the limiting plate are all covered with rubber cushioning pads.
[0011] The beneficial effects of this utility model are:
[0012] This invention uses a combination of a limiting mechanism and an adjustment mechanism to flexibly adjust the limiting range according to the size of the breeding cattle, achieving multi-directional limiting of the abdomen, back, and neck. This avoids poor restraint or animal stress caused by excessively loose or tight restraints. Spatial adjustment is achieved through a mechanical transmission structure, reducing human intervention and significantly improving the safety and efficiency of the breeding cattle restraint process.

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0018] This utility model discloses a restraining device for facilitating vaccine injection in breeding cattle. It mainly includes a support base 1, a limiting mechanism 2, a protective railing 3, and an adjusting mechanism 4. The protective railing 3 is welded to the outside of the support base 1, forming a semi-enclosed area with openings at the front and back to accommodate the breeding cattle. The protective railing 3 is composed of multiple vertically arranged steel pipes with gaps between them, ensuring that the operator can observe the condition of the breeding cattle while preventing them from struggling and escaping the support base 1. Support plates 5 are inclinedly installed at both ends of the support base 1, and are fixed to the support base 1 by welding at an angle of 15°, facilitating the operator to guide the breeding cattle into or out of the support base 1. The surface of the support plates 5 is evenly distributed with anti-slip ridges made of wear-resistant material to increase friction and prevent the breeding cattle from slipping during entry and exit. Guide grooves 11 are provided along the width direction at the front and rear ends of the support base 1, penetrating the front and rear end faces of the support base 1, allowing a push rod 24 to slide within them. The upper surface of the support base 1 is provided with a rectangular through groove 12, which is parallel to the guide groove 11. The bottom end of the scissor bracket 21 passes through the rectangular through groove 12 and is connected to the push rod 24.
[0019] The limiting mechanism 2 is slidably mounted on the support base 1 to limit the movement of the breeding bull around its perimeter. The limiting mechanism 2 includes a scissor-type bracket 21, a first limiting rod 22, a second limiting rod 23, a push rod 24, a limiting plate 25, a support rod 26, an arc-shaped limiting groove 27, a connecting rod 28, and a limiting bar 29. The scissor-type bracket 21 consists of two cross-hinged connecting rods, which are fixed together by a pin to ensure smooth and reliable horizontal extension and contraction, while also ensuring the overall rigidity of the limiting mechanism. The bottom end of the scissor-type bracket 21 passes through a rectangular through groove 12 on the upper surface of the support base 1 and connects to the end of the push rod 24. The top ends of the scissor-type bracket 21 are longitudinally connected to the first limiting rod 22, which is located on both sides of the breeding bull's abdomen to limit the range of motion of the bull's abdomen. The top of the scissor brace 21 is provided with an upwardly inclined support rod 26. A second limiting rod 23 is longitudinally connected between the top ends of the support rods 26. The second limiting rod 23 is located above the back of the breeding bull and is used to restrict the range of motion of the bull's back. The bottom end of the limiting plate 25 is connected to the connecting rod of the scissor brace 21, and the top end is connected to the support rod 26 and located at the front end of the support base 1. An arc-shaped limiting groove 27 is formed on the end face of the limiting plate 25 for limiting the neck of the breeding bull. Two connecting rods 28 parallel to the first limiting rod 22 are connected between the scissor braces 21. Multiple threaded holes are equidistantly formed along the axial direction on the connecting rods 28. Two sets of limiting rods 29 are threadedly connected to the ends of the connecting rods 28. The ends of the limiting rods 29 extend along the outer side of the support base 1 to restrict the range of motion of the bull's limbs, thereby enhancing the restraint effect.
[0020] An adjusting mechanism 4 is installed at the bottom of the support base 1 and connected to the limiting mechanism 2. It drives the limiting mechanism 2 to move horizontally along the support base 1 to accommodate breeding cattle of different sizes. The adjusting mechanism 4 includes a bidirectional lead screw 41, a slider 42, and a handwheel 43. Both ends of the bidirectional lead screw 41 are mounted on the bottom of the support base 1 via bearings. The axis of the bidirectional lead screw 41 is perpendicular to the axis of the push rod 24. One end passes through the side wall of the support base 1 and is connected to the handwheel 43. The slider 42 is installed in the middle of the push rod 24 and is threadedly connected to the bidirectional lead screw 41. When the handwheel 43 is rotated, the bidirectional lead screw 41 drives the slider 42 to move axially, thereby pushing the push rod 24 to slide within the guide groove 11. This drives the scissor bracket 21 to unfold or retract, achieving synchronous adjustment of the limiting mechanism 2. This not only improves operational convenience but also ensures the symmetry and stability of the limiting mechanism 2.
[0021] The surfaces of the first limiting rod 22, the second limiting rod 23, the limiting bar 29, and the limiting plate 25 are all covered with rubber cushioning pads. These pads are firmly attached to the surfaces of each component with adhesive, exhibiting good flexibility and tear resistance, effectively limiting movement while protecting the bull's skin from injury. The curved limiting groove 27 further limits the bull's neck, and the rubber cushioning pads further reduce stress and the risk of injury.
[0022] In actual use, the operator guides the breeding bull through the support plate 5 into the support seat 1 using a rope. The tilt angle and anti-slip ridge design of the support plate 5 allow the breeding bull to enter the support seat 1 smoothly and be positioned inside the limiting mechanism 2. Then, the operator adjusts the position of the limiting mechanism 2 according to the size of the breeding bull and drives the double-acting screw 41 to rotate by rotating the handwheel 43. The double-acting screw 41 drives the slider 42 to move along its axis. The slider 42 pushes the push rod 24 to slide in the guide groove 11. The movement of the push rod 24 causes the scissor bracket 21 to retract. The retraction of the scissor bracket 21 causes the first limiting rod 22, the second limiting rod 23, and the limiting rod 29 to move synchronously, thereby adjusting the limiting space of the breeding bull's abdomen, back, and limbs. At the same time, it drives the arc-shaped limiting groove 27 to limit the neck of the breeding bull. With the use of rubber cushioning pads, the stress response and risk of injury to the breeding bull are effectively reduced. The limiting rod 29 further enhances the limiting effect. After the limiting is completed, the operator can inject the vaccine into the breeding cattle. After the injection is completed, rotate the handwheel 43 in the opposite direction to unfold the scissor bracket 21, release the limiting of the breeding cattle, and the breeding cattle walk out of the support seat 1 through the support plate 5 on the other side of the support seat 1.
[0023] This invention achieves automated adjustment of the limiting mechanism 2 through the linkage design of the scissor bracket 21 and the bidirectional lead screw 41, significantly improving the flexibility and adaptability of restraining breeding cattle. The combination of the arc-shaped limiting groove 27 and the rubber buffer pad reduces the stress response and risk of injury to the breeding cattle. The synchronous movement of the push rod 24 and the slider 42 ensures the symmetry and stability of the limiting mechanism 2, reducing human intervention and greatly improving operational efficiency and safety. To better enable those skilled in the art to fully understand and implement this invention, the following supplementary explanation of the implementation principle of this invention is provided in conjunction with specific application scenarios.
[0024] In actual operation, the operator guides the breeding bull through the support plate 5 into the support seat 1 using a rope. The support plate 5 has an inclination angle of 15° and its surface is evenly distributed with anti-slip ridges made of wear-resistant material, which effectively increases friction and prevents the breeding bull from slipping due to wetness or excessive force. The support plate 5 improves the stability of the breeding bull entering the support seat 1. After the breeding bull enters, the operator needs to adjust the position of the limiting mechanism 2 according to the specific size of the breeding bull. At this time, the handwheel 43 in the adjustment mechanism 4 is rotated, which drives the double-acting screw 41 to rotate. The double-acting screw 41 pushes the slider 42 to move along its axial direction through threaded transmission. The slider 42 is connected to the middle of the push rod 24, so the movement of the slider 42 will further drive the push rod 24 to slide in the guide groove 11.
[0025] The sliding of push rod 24 directly acts on the bottom end of scissor brace 21. Since scissor brace 21 consists of two cross-hinged connecting rods, with its top and bottom ends connected to the first limiting rod 22, the second limiting rod 23, and the limiting rod 29, respectively, the movement of push rod 24 will cause scissor brace 21 to retract. The retracting base of scissor brace 21 simultaneously drives the first limiting rod 22, the second limiting rod 23, and the limiting rod 29 to move, thereby adjusting the limiting space to adapt to the body shape of the breeding bull. The first limiting rod 22 is located on both sides of the breeding bull's abdomen to limit the range of movement of the abdomen; the second limiting rod 23 is located above the breeding bull's back to limit the range of movement of the back; the limiting rod 29 moves with connecting rod 28 to limit the limbs of the breeding bull. The threaded connection of the limiting rod 29 can be finely adjusted according to the specific position of the breeding bull's limbs to enhance the limiting effect.
[0026] Meanwhile, the arc-shaped limiting groove 27 on the limiting plate 25 restricts the bull's neck. The design of the arc-shaped limiting groove 27 allows the bull's neck to move freely within a certain range while avoiding rigid compression. The surfaces of the limiting plate 25, the first limiting rod 22, the second limiting rod 23, and the limiting bar 29 are all covered with rubber cushioning pads. These cushioning pads are firmly attached to the surfaces of each component with adhesive, exhibiting good flexibility and tear resistance. The presence of these rubber cushioning pads not only provides effective restraint but also protects the bull's skin from damage, reducing stress and the risk of injury during restraint.
[0027] After the limiting is completed, the operator can inject the vaccine into the breeding cattle. After the injection is completed, the handwheel 43 is rotated in the opposite direction, the two-way screw 41 is reversed, the slider 42 moves in the opposite direction along its axis, the push rod 24 retracts accordingly, the scissor bracket 21 unfolds, the limiting of the breeding cattle is released, and the breeding cattle walk out of the support seat 1 through the support plate 5. The whole process does not require additional manual intervention, which significantly improves the efficiency and safety of operation.
[0028] In the above steps, the linkage design between the bidirectional lead screw 41 and the scissor brace 21 enables the automated adjustment of the limiting mechanism 2. The telescopic movement of the scissor brace 21 ensures precise adjustment of the limiting space, adapting to the needs of breeding cattle of different sizes. The arc-shaped limiting groove 27, combined with the design of the rubber buffer pad, reduces the rigid pressure on the neck of the breeding cattle, thereby reducing stress response and the risk of injury. In addition, the synchronous movement of the push rod 24 and the slider 42 ensures the symmetry and stability of the limiting mechanism 2, avoiding situations where the limiting is too loose or too tight, further improving the restraint effect.
[0029] The above describes the operating principle and implementation steps of this utility model in a specific application scenario. Through the above structure and operation process, this device can significantly improve the safety and convenience of restraining breeding cattle, meeting the actual needs of the livestock breeding industry.
[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
