Description

Technical Field

[0001] This disclosure relates to the field of livestock equipment technology, and in particular to a head restraint device for livestock. Background Technology

[0002] In livestock farms, in order to prevent and control the occurrence and spread of infectious diseases, intraocular injection of vaccines is often used to vaccinate livestock (such as cattle and sheep).

[0003] Before vaccination, the animal's head needs to be effectively secured by hand. However, due to the animal's strong stress response and activity level, it is prone to agitation and struggle. Furthermore, as the time spent capturing and securing the animal is prolonged, the vaccination personnel become physically exhausted, which can lead to adverse consequences such as the animal escaping, inaccurate vaccine dosage, and the vaccination instrument scratching the animal's eyes. Utility Model Content

[0004] This disclosure provides a head-fixing device for livestock, which aims to solve the technical problem of effectively fixing the head of livestock to reduce the adverse consequences caused by excessive physical exertion of vaccination personnel.

[0005] To solve the above-mentioned technical problems, this disclosure provides a livestock head fixing device, which may include: a frame and a movable mechanism. The frame encloses a target space and has a first opening and a second opening communicating with the target space.

[0033] In livestock farms, in order to prevent and control the occurrence and spread of infectious diseases, intraocular injection of vaccines is often used to vaccinate livestock (such as cattle and sheep).

[0034] Before vaccination, the animal's head needs to be effectively secured by hand. However, due to the animal's strong stress response and activity level, it is prone to agitation and struggle. Furthermore, as the time spent capturing and securing the animal is prolonged, the vaccination personnel become physically exhausted, which can lead to adverse consequences such as the animal escaping, inaccurate vaccine dosage, and the vaccination instrument scratching the animal's eyes.

[0035] The inventors of this disclosure have discovered a head-fixing device for livestock. This device can include a frame and a movable mechanism. The frame has a target space, a first opening, and a second opening. The movable mechanism includes a first movable part, a second movable part, and a stepping part. The first and second movable parts are located at the second opening and face each other. The stepping part is connected to at least one of the first and second movable parts. When the stepping part is subjected to a stepping force (such as a target stepping force) from a vaccination personnel or mechanical equipment, the distance between the first and second movable parts can be reduced. This allows the head (or neck) of a livestock entering the target space from the first opening with its head (or neck) located at the second opening to be held between the first and second movable parts. Thus, the livestock can be reliably fixed using this device, thereby reducing adverse consequences such as livestock escape due to excessive physical exertion by vaccination personnel, inaccurate vaccine dosage, and eye injuries caused by vaccination instruments.

[0036] This disclosure provides a head restraint device 100 for livestock, see [link to previous section]. Figures 1 to 6 As shown, the livestock head fixing device 100 may include: a frame 10 and a movable mechanism 20. The frame 10 encloses a target space 11 and is provided with a first opening 12 and a second opening 13 communicating with the target space 11. The first opening 12 is an opening for livestock to enter and exit the target space 11, and the second opening 13 is used to form a fixing space 131 for the livestock's head. The movable mechanism 20 is connected to the frame 10 and includes: a first movable part 21, a second movable part 22, and a trampling part 23. The first movable part 21 and the second movable part 22 are disposed opposite to each other in the second opening 13, forming a fixing space 131 between them, and the distance between them can be reduced or increased. The trampling part 23 is connected to at least one of the first movable part 21 and the second movable part 22, and can drive the movable part connected to the trampling part 23 to move under the influence of a target trampling force, so as to reduce the distance between the first movable part 21 and the second movable part 22.

[0037] The frame 10 is formed by multiple horizontal bars 14 (circular or rectangular bars extending horizontally) and vertical bars 15 (circular or rectangular bars extending vertically) to create a target space 11. A first opening 12 and a second opening 13, communicating with the target space 11, are formed on the frame 10. Livestock can enter the target space 11 through the first opening 12, and their heads can correspond to a fixed space 131 formed by a moving mechanism 20 at the second opening 13, and be secured by the moving mechanism 20. The first opening 12 and the second opening 13 can be respectively located on opposite sides of the frame 10, or they can be respectively located on adjacent sides of the frame 10, for example: see [link to relevant documentation]. Figures 1 to 6As shown, the first opening 12 and the second opening 13 are respectively located on opposite sides of the frame 10. Livestock can enter the target space 11 through the first opening 12 and quickly enter the second opening 13 without turning their heads.

[0038] The movable mechanism 20 is connected to the frame 10 and can form a fixed space 131 at the second opening 13 of the frame 10. The first movable part 21 and the second movable part 22 are disposed opposite to each other at the second opening 13, and a fixed space 131 can be formed between them. At least one of them is linked with the treading part 23 so that when the treading part 23 is subjected to a target treading force, it can drive the movable parts in the first movable part 21 and the second movable part 22 connected to the treading part 23 to move, thereby reducing the distance between the first movable part 21 and the second movable part 22, so that the head of the animal can be clamped between the first movable part 21 and the second movable part 22.

[0039] See one example. Figures 1 to 6 As shown, the livestock head fixing device 100 may include: a frame 10 and a movable mechanism 20. The frame 10 encloses a target space 11 and is provided with a first opening 12 and a second opening 13 communicating with the target space 11. The first opening 12 is the opening for livestock to enter and exit the target space 11. The second opening 13 is opposite to the first opening 12 and is used to form a fixing space 131 for the livestock's head. The movable mechanism 20 is connected to the frame 10 and includes: a first movable part 21, a second movable part 22 and a trampling part 23. The first movable part 21 and the second movable part 22 are disposed opposite to each other in the second opening 13, forming a fixing space 131 between them, and the distance between them can be reduced or increased. The trampling part 23 is connected to at least one of the first movable part 21 and the second movable part 22, and can drive the movable part connected to the trampling part 23 to move under the influence of a target trampling force (such as an external force from above), so as to reduce the distance between the first movable part 21 and the second movable part 22. One operating procedure for the livestock head restraint device 100 includes:

[0040] S101: The inoculation personnel drive the livestock to the first opening 12, so that the livestock enter the target space 11 through the first opening 12, and the head of the livestock corresponds between the first movable part 21 and the second movable part 22 of the second opening 13.

[0041] S102: The person administering the vaccine presses down on the foot pedal 23 to reduce the distance between the first movable part 21 and the second movable part 22, and clamps the animal's head to fix it between the first movable part 21 and the second movable part 22. Then, the person administering the vaccine can operate the injection instrument to inject the vaccine into the animal's eyes.

[0042] S103: The inoculation personnel increase the distance between the first movable part 21 and the second movable part 22 so that the first movable part 21 and the second movable part 22 can be removed from the fixation of the animal's head, and the animal can leave the animal head fixation device 100 through the first opening 12 or the fixation space 131 between the first movable part 21 and the second movable part 22 to complete the inoculation.

[0043] In this embodiment, the livestock head fixing device 100 may include a frame 10 and a movable mechanism 20. The frame 10 is provided with a target space 11 and a first opening 12 and a second opening 13 communicating with the target space 11. The movable mechanism 20 connected to the frame 10 includes a first movable part 21, a second movable part 22 and a stepping part 23. The first movable part 21 and the second movable part 22 are disposed at the second opening 13 and arranged opposite to each other to form a fixing space 131 for fixing the head of the livestock between them, and the distance between them can be increased or decreased. The stepping part 23 is connected to at least one of the first movable part 21 and the second movable part 22. When the stepping part 23 is subjected to a target stepping force from the vaccination personnel or mechanical equipment, the distance between the first movable part 21 and the second movable part 22 can be reduced, thereby clamping the head of the livestock that enters the target space 11 from the first opening 12 and whose head is located between the first movable part 21 and the second movable part 22 between the first movable part 21 and the second movable part 22. In this way, the head of the animal can be reliably fixed by the head fixing device 100, which can effectively reduce the adverse consequences such as the animal falling off due to excessive physical exertion of the vaccination personnel, inaccurate vaccine dosage, and scratches to the animal's eyes by the vaccination instrument.

[0044] In some embodiments, see Figures 1 to 6 As shown, the movable mechanism 20 also includes a reset structure 24, which is connected to the frame 10 and is used to provide a reset force to the movable parts of the first movable part 21 and the second movable part 22 after the distance between the first movable part 21 and the second movable part 22 decreases.

[0045] In other words, during the process of the target movable part (first movable part 21 and / or second movable part 22) in the first movable part 21 and the second movable part 22 moving to reduce the distance between the first movable part 21 and the second movable part 22, the reset structure 24 can provide a reset force to reset the target movable part, thereby conveniently realizing the increase of the distance between the first movable part 21 and the second movable part 22 to reset.

[0046] In some embodiments, see Figures 1 to 6As shown, the frame 10 may include: a first rod 16, a second rod 17, a third rod 18, and a fourth rod 19. The first rod 16, the second rod 17, the third rod 18, and the fourth rod 19 are connected in sequence to form a rectangular second opening 13. The first rod 16 is rotatably connected to the stepping part 23 on the side facing away from the third rod 18. The two ends of the first movable part 21 are slidably sleeved on the second rod 17 and the fourth rod 19, respectively. The two ends of the second movable part 22 are slidably sleeved on the second rod 17 and the fourth rod 19, respectively. The first movable part 21 and the second movable part 22 are close to or far away from each other along the second rod 17 and the fourth rod 19.

[0047] Thus, during the process of reducing the distance between the first movable part 21 and the second movable part 22 to clamp the animal's head, the first movable part 21 and the second movable part 22 slide along the second rod 17 and the fourth rod 19, thereby making the clamping process smoother and more accurate (or with a smaller deviation rate). Here, the first rod 16 and the third rod 18 can be vertical rods 15, and the second rod 17 and the fourth rod 19 can be horizontal rods 14.

[0048] In some embodiments, see Figures 1 to 6 As shown, the active mechanism 20 includes: a first sliding member 25, a second sliding member 26, and a linkage structure 27. The first sliding member 25 is slidably connected to the first rod 16 and movably connected to the first active part 21. The second sliding member 26 is slidably connected to the third rod 18 and movably connected to the second active part 22. The linkage structure 27 is movably connected to the footing part 23, the first sliding member 25, and the second sliding member 26 respectively. When the footing part 23 is subjected to a target footing force, the linkage structure 27 drives the first sliding member 25 and the second sliding member 26 to slide in opposite directions, so that the first sliding member 25 and the second sliding member 26 respectively provide a force to the first active part 21 and the second active part 22 to bring them closer together.

[0049] The lengths of the first slider 25 and the second slider 26 can be the same. In the initial state, the heights of the first slider 25 and the second slider 26 can be the same, so that the first slider 25 and the second slider 26 are in a position opposite to each other between the first rod 16 and the third rod 18. Then, when the stepping part 23 is subjected to the target stepping force, the linkage structure 27 can transmit the movement of the stepping part 23 to the first slider 25 and the second slider 26, so as to drive the first slider 25 and the second slider 26 to slide in opposite directions relative to the first rod 16 and the third rod 18 respectively, thereby realizing that the first movable part 21 connected to the first slider 25 and the second movable part 22 connected to the second slider 26 respectively move closer to each other.

[0050] In this embodiment, the linkage structure 27 converts the single stepping force of the stepping part 23 into the motion force of the first sliding member 25 and the second sliding member 26, thereby driving the first movable part 21 connected to the first sliding member 25 and the second movable part 22 connected to the second sliding member 26 to move closer to each other, thus avoiding the use of two independent drive mechanisms and simplifying the overall structure.

[0051] In some embodiments, see Figures 1 to 6 As shown, the linkage structure 27 may include: a first link 271, a second link 272, a third link 273, a first guide 274, a second guide 275, and a pull rope 276. The two ends of the first link 271 are rotatably connected to the foot pedal 23 and the first sliding member 25, respectively. The two ends of the second link 272 are rotatably connected to the first sliding member 25 and the first movable part 21, respectively. The two ends of the third link 273 are rotatably connected to the second sliding member 26 and the second movable part 22, respectively. The first guide 274 and the second guide 275 are respectively disposed on the first rod 16 and the second rod 17 on the same side of the frame 10. The two ends of the pull rope 276 are respectively connected to the first sliding member 25 and the second sliding member 26, and the pull rope 276 is wound around the first guide 274 and the second guide 275 and can move along the first guide 274 and the second guide 275.

[0052] A first pin can be provided on the pedal part 23, and a second pin can be provided on the first sliding member 25. The two ends of the first connecting rod 271 can be rotatably sleeved on the first pin and the second pin, respectively. When the pedal part 23 is subjected to a target pedaling force, the first connecting rod 271 rotates relative to the first pin and moves with the pedal part 23, simultaneously causing the first connecting rod 271 to rotate relative to the second pin and drive the first sliding member 25, which has the second pin, to slide relative to the first rod body 16. A third pin can be provided on the first sliding member 25, and a fourth pin can be provided on the first movable part 21. The two ends of the second connecting rod 272 can be rotatably sleeved on the third pin and the second pin, respectively. The fourth pin; the second sliding member 26 may be provided with a fifth pin, the second movable part 22 may be provided with a sixth pin, and the two ends of the third connecting rod 273 may be rotatably sleeved on the fifth pin and the sixth pin respectively; the second sliding member 26 is connected to the first sliding member 25 through a pull rope 276, and the pull rope 276 is wrapped around the same side of the rectangular frame formed by the first rod 16, the second rod 17, the third rod 18 and the fourth rod 19 in a U-shape, so that the second sliding member 26 can slide relative to the third rod 18 as the first sliding member 25 slides through the pull rope 276, and the pull rope 276 is U-shaped, so that the sliding directions of the second sliding member 26 and the first sliding member 25 are opposite.

[0053] The first guide member 274 may have a recessed first arc-shaped surface, the arc direction of which may be consistent with the turning trajectory of the first rod 16 and the second rod 17. The second guide member 275 may have a recessed second arc-shaped surface, the arc direction of which may be consistent with the turning trajectory of the second rod 17 and the third rod 18. The pull rope 276 abuts against the first arc-shaped surface and the second arc-shaped surface and moves along the first arc-shaped surface and the second arc-shaped surface. Compared with the arrangement of the pull rope 276 directly along the edge of the corner of the first rod 16 and the second rod 17 and the second rod 17 and the third rod 18, the edge of the rectangular frame can avoid wear on the pull rope 276 and improve the smoothness of the movement of the pull rope 276.

[0054] In this embodiment, the linkage structure 27 may include a first link 271, a second link 272, a third link 273, a first guide 274, a second guide 275, and a pull rope 276. The first link 271 converts the target stepping force on the foot pedal 23 into a sliding force of the first sliding member 25 relative to the first rod 16. The second link 272 converts part of the motion force of the first sliding member 25 into a force of the first movable part 21 approaching the second movable part 22. The pull rope 276 converts part of the motion force of the first sliding member 25 into a force of the second sliding member 25 approaching the second movable part 22. The sliding force of the moving member 26 relative to the third rod 18 can be converted into a force that brings the second movable part 22 closer to the first movable part 21 through the third connecting rod 273. This allows the first movable part 21 and the second movable part 22 to move closer to each other. The connecting rods (such as the first connecting rod 271, the second connecting rod 272 and the third connecting rod 273) and the pull rope 276 have simple structures and are easy to manufacture. At the same time, the first guide member 274 and the second guide member 275 can prevent the edge from causing wear on the pull rope 276 and improve the smoothness of the movement of the pull rope 276.

[0055] In some embodiments, see Figures 1 to 6 As shown, the first guide member 274 is a first roller that can rotate relative to the frame 10. The first roller has a first groove on its periphery. The pull rope 276 passes through the part of the first groove away from the frame 10 and can move along the first groove. The second guide member 275 is a second roller that can rotate relative to the frame 10. The second roller has a second groove on its periphery. The pull rope 276 passes through the part of the second groove away from the frame 10 and can move along the second groove.

[0056] Alternatively, as the pull rope 276 moves along the first guide 274 and the second guide 275, the first roller and the second roller roll relative to the frame 10, which can further reduce the probability of wear on the pull rope 276.

[0057] In some embodiments, see Figures 1 to 6As shown, multiple second links 272 are arranged in parallel, and one end of one second link 272 and one end of the first link 271 are rotatably connected to the same pin of the first sliding member 25; multiple third links 273 are arranged in parallel.

[0058] Multiple second links 272 are arranged in parallel, which allows the first sliding member 25 to drive the first movable part 21 closer to the second movable part 22 more smoothly, and the livestock head fixing device 100 has higher structural strength. One end of one of the second links 272 and one end of the first link 271 are rotatably connected to the same pin of the first sliding member 25, so as to reduce the number of pins.

[0059] Multiple third links 273 are arranged in parallel, which allows the second sliding member 26 to drive the second movable part 22 closer to the first movable part 21 more smoothly, and the livestock head fixing device 100 has higher structural strength.

[0060] In some embodiments, see Figures 1 to 6 As shown, the reset structure 24 includes at least one of a first reset member 241, a second reset member 242, and a third reset member 243. The two ends of the first reset member 241 are respectively connected to the first rod 16 and the first movable part 21, and can generate an elastic stretching amount when the first movable part 21 moves closer to the second movable part 22. The two ends of the second reset member 242 are respectively connected to the third rod 18 and the second movable part 22, and can generate an elastic stretching amount when the second movable part 22 moves closer to the first movable part 21. The two ends of the third reset member 243 are respectively connected to the third rod 18 and the second sliding member 26, and can generate an elastic stretching amount when the second movable part 22 moves closer to the first movable part 21.

[0061] The two ends of the first reset member 241 are connected to the first rod 16 and the first movable part 21, respectively, and can generate an elastic stretch during the process of the first movable part 21 approaching the second movable part 22. Thus, after the restraining force (such as the target stepping force) that makes the first movable part 21 and the second movable part 22 approach each other is removed, the first reset member 241 returns to its original state, so that the first movable part 21 and the second movable part 22 can be easily returned to their relative positions before approaching each other.

[0062] The two ends of the second reset member 242 are respectively connected to the third rod 18 and the second movable part 22, and can generate elastic tension as the second movable part 22 approaches the first movable part 21. Thus, after the restraining force (such as the target stepping force) that makes the first movable part 21 and the second movable part 22 approach each other is removed, the second reset member 242 returns to its original state, so that the first movable part 21 and the second movable part 22 can be easily returned to their relative positions before approaching each other.

[0063] The two ends of the third reset member 243 are connected to the third rod 18 and the second sliding member 26 respectively, and can generate elastic tension as the second movable part 22 moves closer to the first movable part 21. Thus, after the restraining force (such as the target stepping force) that makes the first movable part 21 and the second movable part 22 move closer to each other is removed, the third reset member 243 returns to its original state, so as to drive the second sliding member 26 back to its position before sliding, thereby driving the second movable part 22 to easily return to its position before moving closer to the first movable part 21.

[0064] The first reset member 241, the second reset member 242, and the third reset member 243 can be as follows: Figures 1 to 6 The spring shown can also be other elastic structural components.

[0065] In some embodiments, see Figures 1 to 6 As shown, a first elastic limiting part 211 is provided on the side of the first movable part 21 near the second movable part 22; a second elastic limiting part 221 is provided on the side of the second movable part 22 near the first movable part 21; the first elastic limiting part 211 and the second elastic limiting part 221 are opposite to each other and form a fixed space 131 between them, and the two opposing surfaces of the first elastic limiting part 211 and the second elastic limiting part 221 are respectively arc-shaped recesses in the direction away from each other.

[0066] In other words, the first elastic limiting part 211 is disposed on the first movable part 21, and the second elastic limiting part 221 is disposed on the second movable part 22. The arc-shaped recessed design of the two opposing surfaces of the first elastic limiting part 211 and the second elastic limiting part 221 can form a circular, elliptical or other fixed space 131 between the first elastic limiting part 211 and the second elastic limiting part 221, so as to be closer to the outline of the animal's head or neck, thereby making the fixation effect on the animal's head better.

[0067] The first elastic limiting part 211 can be a structural component made of elastic materials such as rubber or silicone, and the second elastic limiting part 221 can be a structural component made of elastic materials such as rubber or silicone.

[0068] In some embodiments, the frame 10 may further include a limiting member movably disposed on the first opening 12, capable of switching between avoiding the first opening 12 and covering at least a portion of the first opening 12; when covering at least a portion of the first opening 12, livestock in the target space 11 are blocked by the limiting member, preventing them from leaving the target space 11 through the first opening 12, thereby better confining the livestock in the target space 11; while when avoiding the first opening 12, the livestock can leave the target space 11 through the first opening 12. For example, the limiting member may be a door hinged to the first opening 12, the door rotating relative to the frame 10 to switch between opening the first opening 12 (e.g., avoiding the first opening 12) and closing the first opening 12 (e.g., covering the entire first opening 12).
