[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The purpose of the utility model is to provide a self-locking neck clamp for dairy goats to solve the problems existing in the above-mentioned related technologies, simplify the structure of the self-locking neck clamp for dairy goats, improve the locking reliability of the neck clamp, and reduce production and maintenance costs.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] Example 1

[0034] This embodiment provides a self-locking neck clamp for dairy goats. Figures 1-6 , including a neck clamp mechanism and a locking mechanism, wherein the neck clamp mechanism includes a main frame 1, the main frame 1 can be fixed on the animal pen 16, the main frame 1 includes a fixing element, and the fixing element is used to separate a plurality of upper slots 2, each upper slot 2 is provided with a locking rod 3, the locking rod 3 is hinged to the main frame 1, and the locking rod 3 is rotated relative to the main frame 1 to achieve locking and unlocking of the upper slot 2; the locking mechanism includes a locking shaft 4, a locking sleeve 5 and a locking piece 6, the locking shaft 4 is connected to the main frame 1, and one end of the locking sleeve 5 is connected to the locking rod 3 The other end of the locking sleeve 5 is hinged to the locking piece 6, and the locking sleeve 5 is slidably connected to the locking shaft 4. The locking rod 3 and the locking piece 6 are respectively located on both sides of the locking shaft 4; the locking shaft 4 is provided with a card block 7. When the locking rod 3 is in a free state under the action of gravity, the locking piece 6 can abut against the card block 7 and limit the locking sleeve 5 from sliding along the locking shaft 4 to achieve locking of the upper slot 2; the locking piece 6 can rotate relative to the locking sleeve 5 and cross the card block 7, so that the locking sleeve 5 can slide along the locking shaft 4 and drive the locking rod 3 to deflect, so as to achieve unlocking of the upper slot 2.

[0035] The present invention relates to a self-locking neck clamp for dairy goats. The fixing element separates the main frame 1 into an upper slot 2. The upper slot 2 is provided with a locking rod 3. The locking rod 3 can rotate to lock and unlock the upper slot 2. When the locking rod 3 is in a free state under the action of gravity, the locking piece 6 abuts against the clamping block 7 to restrict the rotation of the locking rod 3. At this time, the animal's head cannot pass through the gap between the locking rod 3 and the main frame 1, thereby locking the upper slot 2. The locking piece 6 is rotated to separate from the clamping block 7 and drive the locking sleeve 5 to slide along the locking shaft 4. The locking sleeve 5 drives the locking rod 3 to rotate. At this time, the gap between the locking rod 3 and the main frame 1 allows the animal's head to pass through, unlocking the upper slot 2. After the animal's head passes through the upper slot 2 and the locking rod 3 is reset, the locking piece 6 still abuts against the clamping block 7 to lock the animal. The present invention has a simple structure, convenient locking and unlocking operations, and reliable locking. It greatly improves the adaptability of the self-locking neck clamp for dairy goats and reduces the production cost of animal husbandry.

[0036] It should be explained here that, in actual application, the main frame 1 can be fixed to the animal pen 16 to facilitate the use of the self-locking neck clamp for dairy goats. In addition, the number and distribution of the upper slots 2 in the neck clamp mechanism can be adjusted according to actual use requirements.

[0037] The locking sleeve 5 is a U-shaped groove structure with an open top. The bottom of the locking sleeve 5 is connected to the top of the locking rod 3. The locking shaft 4 is located in the U-shaped groove of the locking sleeve 5. The locking piece 6 is located above the locking shaft 4 and is hinged to the two side walls of the locking sleeve 5. While the locking sleeve 5 slides along the locking shaft 4, the locking sleeve 5 will also deflect due to the rotation of the locking rod 3. In this specific embodiment, the locking sleeve 5 is configured as a U-shaped groove structure to ensure that the locking sleeve 5 can move smoothly, thereby ensuring that the locking rod 3 can rotate smoothly, thereby improving the operation reliability of the self-locking neck clamp for dairy goats. In addition, the locking piece 6 is hinged to the two side walls of the locking sleeve 5, providing sufficient space for the locking piece 6 to move, further improving the locking and unlocking reliability of the self-locking neck clamp for dairy goats.

[0038] In this specific embodiment, the locking piece 6 is an L-shaped bending structure, one bending arm of the locking piece 6 is hinged to the locking sleeve 5, and the other bending arm of the locking piece 6 can be abutted against the card block 7. The locking piece 6 is set to a bending structure to ensure that the locking piece 6 is in full contact with the card block 7 and is convenient for operation.

[0039] Specifically, a locking pin is connected to the middle of the locking piece 6, and the locking pin is rotatably connected to the two side walls of the locking sleeve 5, ensuring that the locking piece 6 rotates smoothly and further improving the working reliability of the locking mechanism.

[0040] More specifically, the main frame 1 also includes an upper cross bar 8 and a lower cross bar 9 arranged in parallel, the locking shaft 4 is located at the top of the upper cross bar 8, the fixing element connects the upper cross bar 8 and the lower cross bar 9, and the fixing element includes a first fixing rod 10 and a second fixing rod 11. The first fixing rod 10 is vertically arranged, and the second fixing rod 11 is an inverted Y-shaped structure. The locking rod 3 is arranged between the first fixing rod 10 and the second fixing rod 11, and the middle part of the locking rod 3 is hinged to the second fixing rod 11. The second fixed rod 11 is an inverted Y-shaped structure. The lower half of the second fixed rod 11 has two supporting rods. The locking rod 3 is hinged to a rod near the first fixed rod 10. When the locking rod 3 rotates, the bottom of the locking rod 3 contacts the first fixed rod 10 and rotates into place. The distance between the top of the locking rod 3 and the first fixed rod 10 reaches the maximum, allowing the animal's head to pass through, and the upper slot 2 is unlocked. When the animal lowers its head to feed, it presses down on the lower half of the locking rod 3, pushing the locking rod 3 back to its original position. The locking piece 6 passes over the block 7 and then resets. At this time, the distance between the upper half of the locking rod 3 and the first fixed rod 10 is reduced, preventing the animal's head from passing through. The upper slot 2 returns to the locked state, achieving self-locking, further improving the locking reliability of the self-locking neck clamp for dairy goats. The locking rod 3 and the locking piece 6 of the utility model both adopt a lever structure, which is simple in structure and reliable in movement. It is also necessary to explain here that, in addition, the block 7 and the locking piece 6 are both located on the side of the locking rod 3 close to the second fixed rod 11, that is, the block 7 and the locking piece 6 are both located on the side of the sliding path when the locking sleeve 5 is unlocked, so as to ensure locking reliability.

[0041] The locking rod 3 is connected to a connecting pin 12 , and the locking rod 3 is hinged to the second fixing rod 11 by means of the connecting pin 12 , which facilitates assembly and maintenance of the locking rod 3 and the second fixing rod 11 .

[0042] It should also be noted that a blocking plate 13 is also connected to the side of the locking rod 3 close to the second fixed rod 11. The blocking plate 13 is located between the connecting pin 12 and the locking sleeve 5, and the contour shape of the blocking plate 13 close to the second fixed rod 11 matches the shape of the second fixed rod 11. The blocking plate 13 can block the gap between the locking rod 3 and the top of the second fixed rod 11, thereby effectively preventing the animal's head from passing through the gap between the locking rod 3 and the top of the second fixed rod 11 when the locking rod 3 is locked, thereby improving the locking reliability of the self-locking neck clamp for dairy goats.

[0043] In practical applications, in each neck clamp mechanism, the number of upper slots 2 can be multiple groups, and the locking sleeves 5 and locking plates 6 correspond one-to-one with the locking rods 3 to meet the locking requirements of different animal pens 16 and different animals.

[0044] In addition, there are multiple groups of neck clamp mechanisms, all of which are arranged side by side, and the main frame 1 of each neck clamp mechanism is connected to the locking shaft 4. The side-by-side installation of the neck clamp mechanisms is achieved using a locking shaft 4, which is conducive to simplifying the structure of the self-locking neck clamp for dairy goats.

[0045] It should also be emphasized that in other achievable specific embodiments of the present invention, the locking shaft 4 is rotatably connected to the main frame 1, and the side walls of the locking shaft 4 are provided with multiple groups of limiting elements, all of which are arranged circumferentially around the axis of the locking shaft 4; each group of limiting elements includes multiple blocks 7, and the blocks 7 in each group of limiting elements are arranged along the axial direction of the locking shaft 4, and the spacing between the blocks 7 of different groups of limiting elements is different. In the limiting elements, the spacing between adjacent blocks 7 can be determined according to actual locking requirements. When the spacing between adjacent blocks 7 is consistent with the spacing between the locking rods 3 in adjacent upper slots 2, all upper slots 2 can be locked; when the spacing between adjacent blocks 7 is twice the spacing between adjacent locking rods 3, it is possible to lock one upper slot 2 every other upper slot 2. For details, please refer to Figure 6 When the locking shaft 4 rotates to the upper group of limiting elements and the locking piece 6, the locking of 2N upper slots 2 is achieved. When the locking shaft 4 rotates to the lower group of limiting elements and the locking piece 6, the locking of N upper slots 2 is achieved, and the interval locking of the upper slots 2 is achieved to reserve a larger operating space, wherein N is a natural number greater than 0. In addition, the spacing between adjacent blocks 7 of the limiting element can also be set to irregular intervals according to actual needs to meet the locking requirements of different upper slots 2 and improve the flexibility and adaptability of the self-locking neck clamp for dairy goats. The locking situation can be adjusted by rotating the locking shaft 4 of the utility model to meet different locking requirements. The structure is simple and easy to operate. At the same time, when unlocking the upper slot 2, the locking shaft 4 can also be rotated to drive the block 7 to rotate to the side away from the locking piece 6. The block 7 is disengaged from the locking piece 6 to achieve rapid unlocking of multiple upper slots 2.

[0046] Furthermore, a shaft sleeve 14 is provided on the main frame 1, and the locking shaft 4 can rotatably pass through the shaft sleeve 14. The rotation axis of the locking shaft 4 is parallel to the sliding direction of the locking sleeve 5, ensuring the smoothness of the rotation of the locking shaft 4 and providing stable support for the locking shaft 4.

[0047] For ease of operation, the locking shaft 4 is connected to an adjustment handle 15, which can drive the locking shaft 4 to rotate, reducing the operator's workload. In order to avoid misoperation and prevent animals from colliding with the self-locking neck clamp for dairy goats, which may cause the locking shaft 4 to rotate out of position, the adjustment handle 15 is hinged to the locking shaft 4, and the hinge axis of the two is perpendicular to the rotation axis of the locking shaft 4. A stop groove 17 is provided on the main frame 1. The adjustment handle 15 can rotate relative to the locking shaft 4 and extend into the stop groove 17 to fix the position of the locking shaft 4 and the main frame 1. After the operation is completed, the adjustment handle 15 is rotated into the stop groove 17 to avoid misalignment of the locking shaft 4, improve the structural stability of the locking shaft 4, and avoid misoperation. For details, see Figure 6 The dotted line in the figure shows the state where the adjustment handle 15 is rotated into the stop groove 17. It should also be noted that the hinge axis between the adjustment handle 15 and the locking shaft 4 is perpendicular to the rotation axis of the locking shaft 4, and the rotation of the adjustment handle 15 does not affect the rotation of the locking shaft 4.

[0048] Example 2

[0049] This embodiment provides a self-locking neck clamp for dairy goats. The structure of the self-locking neck clamp for dairy goats in this embodiment is the same as that in the first embodiment.

[0050] In this embodiment, each set of neck clamp mechanisms has nine upper slots 2. The main frame 1 has a total length of 2.9 m and a height of 1.2 m. When each upper slot 2 is in the unlocked state, the maximum gap between the locking rod 3 and the first fixed rod 10 is 28 cm. The vertical distance between the hinged joint of the locking rod 3 and the first fixed rod 10 and the forage position is 55 cm. When the upper slots 2 are in the locked position, the spacing between the locking rod 3 and the first fixed rod 10 is 13 cm. The maximum vertical height that the upper slots 2 can accommodate sheep is 88 cm. It should be noted that the vertical dimensions of the self-locking neck clamp for dairy goats can also be adjusted by adjusting the installation position of the self-locking neck clamp for dairy goats and the animal pen 16 to meet different locking requirements. When the self-locking neck clamp for dairy goats is applied to other animals or to meet different locking requirements, the above dimensions can be adjusted according to specific working conditions.

[0051] In this specific embodiment, every four groups of neck clamp mechanisms are connected to a locking shaft 4, and two groups of limiting elements are set, which can lock 36 dairy goats at the same time; by adjusting the locking shaft 4, 18 goats can be locked at the same time, and the locking method is one position at a time (leaving enough operating space), and the other 18 positions are locked and the goats cannot be boarded.

[0052] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
