[0030] The technical features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] As shown in the figure, this utility model is a sheep catcher with a position holding device, including a base plate 1. In one embodiment of this application, the base plate 1 can be in the form of a rectangular frame welded from square steel pipes. In other embodiments of this application, some supporting steel pipes can be welded and fixed inside the rectangular frame welded from square steel pipes to increase the supporting rigidity of the base plate 1.

[0032] In this application, two side door assemblies, a rear guard plate 2, and a set of clamping and turning mechanisms are provided on the base plate 1. The two side door assemblies are located at both ends of the upper surface of the base plate 1, and the rear guard plate 2 and the clamping and turning mechanisms are located on both sides of the upper surface of the base plate 1. An internal space is enclosed by the two side door assemblies, the rear guard plate 2, and the set of clamping and turning mechanisms. Sheep enter and exit through the two side door assemblies. After entering, they are held in position and turned over by the clamping and turning mechanisms to facilitate operations such as vaccination.

[0033] In one embodiment of this application, the rear guard plate 2 can be constructed using a welded steel pipe frame with an acrylic sheet attached to the frame, forming a closed plate-like structure. In other embodiments of this application, the rear guard plate 2 can also be constructed using only welded steel pipes or simply using a common plate-like structure such as acrylic sheet.

[0034] In one embodiment of this application, the side door assembly includes a rectangular frame door frame 501 and a door body 502 disposed within the door frame 501. The door body 502 is pivotally connected to the door frame 501, and a lock body is provided between the door body 502 and the door frame 501 to lock the relative position of the door body 502 and the door frame 501. In other embodiments of this application, the side door assembly may also adopt other door body forms that can be opened and closed.

[0035] In this application, the clamping and flipping mechanism includes a plate-shaped bracket 3 and a plate-shaped upper clamping device 4. Both ends of the bracket 3 are rotatably connected to the side door assembly via pivots. One side of the upper clamping device 4 is pivotally connected to the bracket 3, and the other side of the upper clamping device 4 has a lower clamping mechanism. After the upper clamping device 4 and the bracket 3 rotate around their pivot axis, the bracket 3, the upper clamping device 4, and the lower clamping mechanism combine to form a clamping and fixing space for the livestock. Several torsion springs 6 are provided at the pivot axis between the upper clamping device 4 and the bracket 3, and a ratchet fixing mechanism is provided between the upper clamping device 4 and the bracket 3 to fix the angle between them.

[0036] The door frame 501 has a support frame on the side surface facing the bracket 3, and the bracket 3 is rotatably connected to the support frame via a pivot.

[0037] In one embodiment of this application, multiple threaded holes can be provided on the side surface of the bracket 3. These threaded holes can be evenly spaced along the plate-like side surface of the bracket 3. The pivot between the bracket 3 and the support frame can be fixed within these threaded holes via a threaded connection. By adjusting the position of the pivot between the bracket 3 and the support frame, the overall center can be adjusted after the clamping and flipping mechanism clamps and flips the sheep, preventing the entire clamping and flipping mechanism from rotating. Based on this, a support protrusion can be welded and fixed at a corresponding position on the support frame. When the clamping and flipping mechanism clamps and flips the sheep, the support protrusion can support the bracket 3. Due to the influence of the center of gravity, the bracket 3 can rest on the support protrusion and will not rotate.

[0038] In one embodiment of this application, the two sides of the rear guard plate 2 are respectively fixedly connected to two side door assemblies by bolts, and the rear guard plate 2 and the two side door assemblies form a U-shape. The lower end of the rear guard plate 2 is fixedly connected to the base plate 1 by bolts. Several main components of this application are connected to each other by bolts, which facilitates disassembly. During the epidemic prevention process in pastoral areas, more sheep catchers can be loaded on mobile vehicles for convenient transportation and use in pastoral areas.

[0039] The lower clamping mechanism includes two clamping bends 7. The ends of the two clamping bends 7 are fixed to the sides of the upper clamping device 4. The middle section of the clamping bends 7 has a bend. The ends of the clamping bends 7 are perpendicular to or at an obtuse angle to the upper clamping device 4. The bend in the middle section of the clamping bends 7 is at an acute angle to the upper clamping device 4.

[0040] In this application, when the upper clamping device 4 and the bracket 3 are rotated and folded to form an acute angle, the clamping bend 7 is secured to the sheep's belly. The upper clamping device 4, the bracket 3, and the clamping bend 7 together form a triangular clamping structure around the sheep, thus fixing the sheep in place. Then, by rotating the bracket 3 around the pivot between it and the support frame, the sheep can be turned over for easy vaccination or disease control checks.

[0041] In one embodiment of this application, the end of the clamping bend 7 has a sleeve, and the upper clamping device 4 has a sliding rod. The sleeve is sleeved on the sliding rod and slides along the sliding rod. The sleeve is provided with a plurality of clamping bolts, which pass through the sleeve wall and are threadedly connected to the sleeve. The ends of the clamping bolts are in tight contact with the surface of the sliding rod.

[0042] By sliding the clamping bend 7 on the sliding rod of the upper clamping device 4, the position of the clamping bend 7 and the spacing between each clamping bend 7 can be adjusted to accommodate the sustenance operation of sheep of different sizes and breeds.

[0043] In one embodiment of this application, the ratchet fixing mechanism includes a ratchet 901 and a pawl 902. The ratchet 901 has ratchet teeth on its rim surface, and the pawl 902 has a pawl at its end that engages with the ratchet teeth on the rim of the ratchet 901. The ratchet 901 is mounted on a bracket 3, and the pawl 902 is positioned on the upper clamping device 4 at a location that engages with the ratchet 901.

[0044] The pawl handle 902 is L-shaped, and the L-shaped bend of the pawl handle 902 is rotatably connected to the upper clamping device 4 via a pivot. A tension spring 903 is provided between the pawl handle 902 and the upper clamping device 4 to press the pawl onto the ratchet teeth.

[0045] In this embodiment, the ratchet fixing mechanism adopts a ratchet structure commonly used in the prior art, and its specific structural form is relatively mature.

[0046] In other embodiments of this application, angle limiting and fixing mechanisms with other structural forms may also be used, such as a damping hinge that can stop at any angle between the upper clamping device 4 and the bracket 3.

[0047] The technical solution of this application will be further elaborated below in conjunction with the instructions for use.

[0048] Before using this application, such as Figure 4 As shown, pull the pawl handle 902 to disengage the pawl from the ratchet teeth on the rim surface of the ratchet 901, adjusting the opening angle between the upper clamping device 4 and the bracket 3 to its maximum. Adjust the position of the clamping bend 7 according to the size of the sheep's belly and tighten the bolts to secure it. After opening the lock body, open one of the doors 502 while closing the other door 502, allowing the sheep to enter.

[0049] like Figure 5 As shown, the doors at both ends are locked after the sheep enters. Then, as... Figure 6 As shown, when the upper clamping device 4 is pulled down, the pawl moves on the rim surface of the ratchet 901. After the upper clamping device 4 and the bracket 3 clamp the sheep, the pawl gets stuck in the tooth groove of one of the ratchet teeth on the rim surface of the ratchet 901, so that the angle between the upper clamping device 4 and the bracket 3 is locked, tightly holding the sheep inside.

[0050] like Figure 7 As shown, after the above steps are completed, pull the bracket 3 to make the bracket 3 and the support frame of the door frame 501 rotate relative to each other, thereby causing the upper clamping device 4 and the sheep to reverse outward together, so that the sheep is firmly held in the upper clamping device 4 and the bracket 3, and the sheep's belly and body are completely exposed on the side, so that the disease prevention work can begin.

[0051] like Figure 8 As shown, after the quarantine work is completed, lifting one side of the bracket 3 causes the bracket 3 and the support frame of the door frame 501 to rotate relative to each other, allowing the sheep to return to a standing position. Pulling the upper clamping device 4 upward and moving the pawl handle 902 allows the upper clamping device 4 and the bracket 3 to return to their maximum opening angle, freeing the sheep from its restraints. Opening the door at the end facing the sheep's head allows the sheep to leave the sheep catcher.

[0052] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
