Description

Technical Field

[0001] The utility model relates to the technical field of piglet castration devices, in particular to a fixing device for piglet castration. Background Art

[0002] Castration of piglets means castration of piglets. Pig farms usually raise boars after castration. First, it is easy to manage, and second, it saves costs. If boars are not castrated, the effect of male hormones in their bodies can easily cause pigs to fight for food, territory, and bosses. When the fight is fierce, the pigs will not only not grow but lose weight, and sometimes they will be bitten to death, causing unnecessary losses. After pigs reach sexual maturity, the effect of sex hormones will also affect their weight gain. Castrated pigs are not affected by sex hormones, have a high feed conversion rate, and grow naturally fast, which greatly saves feeding costs.

[0003] When castrating piglets, a piglet castration rack is required. Chinese patent CN220158463U discloses a hanging vertical piglet castration rack, which includes a mounting plate, a base is arranged on the mounting plate, a beam assembly is arranged on the base, a hind leg rack is arranged on the beam assembly, a telescopic sleeve rod is arranged at the end of the beam assembly, an arc tube is arranged on the telescopic sleeve rod, a slidable slider is arranged on the beam assembly, and limited clamps are arranged at both ends of the slider. A bottom plate is arranged at the bottom of the mounting plate, a vertical rod is arranged on the bottom plate, an electric telescopic rod is arranged on the vertical rod, a matching card holder that matches the arc tube is arranged on the electric telescopic rod, and a collection box for collecting garbage is also arranged on the bottom plate. The hind legs of the piglet are fixed by the hind leg rack to avoid incorrect castration orientation due to pain and struggle of the piglet, thereby ensuring the smooth progress of the castration operation and improving work efficiency.

[0004] The device limits the pig's hind legs by setting two arch rings, so that when the piglet is hung upside down, the piglet's hind legs are fixed tightly in the arch ring by the piglet's weight. When the piglet struggles during castration, the pig's hind legs are easily fixed and injured, and the pig's body struggles and shakes, and the pig's legs are easily detached from the bottom of the arch ring, affecting the castration efficiency.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3The utility model provides a technical solution: a fixing device for castration of piglets, comprising a Y-shaped frame 1, a baffle 2 is welded at one end of the vertical rod of the Y-shaped frame 1, a hanging structure 3 for fixing the device to the pigpen railing is arranged on one side of the baffle 2, a spring clip 4 for limiting the position of pig legs is welded on the outer wall of the vertical rod of the Y-shaped frame 1, a fixing rod 5 is arranged on one side of the spring clip 4, one end of the fixing rod 5 is welded to the Y-shaped bracket, the other end of the fixing rod 5 is rotatably connected with a limiting hoop 6 for limiting the position of the pig body, and the other end of the fixing rod 5 is provided with a reset structure 7 for facilitating the rotation and reset of the limiting hoop 6.

[0021] When the piglet is hung upside down with its face facing the baffle 2, the limiting hoop 6 limits the piglet's trunk between the annular plate 601 and the Y-shaped frame 1. The limiting hoop 6 can reduce the range of motion of the piglet when it struggles, thus preventing the piglet from affecting castration due to excessive movements, thereby improving castration efficiency.

[0022] The limiting hoop 6 includes an annular plate 601 and a rotating rod 602 . The rotating rod 602 is welded to one end of the limiting hoop 6 . The top end of the rotating rod 602 penetrates the fixing rod 5 and is rotatably connected to the fixing rod 5 .

[0023] By setting the limiting hoop 6 to be rotatable, it is convenient for the piglets to be placed in the bifurcated end of the Y-shaped frame 1. Figure 1 As shown, manually pushing the annular plate 601 to the right can cause the rotating rod 602 to rotate and the annular plate 601 to open.

[0024] The reset structure 7 includes a welding block 701, a tension spring 702 and a limit block 703. The welding block 701 is welded to the outer wall of the rotating rod 602. One end of the tension spring 702 is fixedly connected to the welding block 701. The other end of the tension spring 702 is fixedly connected to one side of the fixed rod 5. The limit block 703 is welded to the outer wall at the top end of the rotating rod 602. The limit block 703 is arranged in an inverted L shape.

[0025] When the annular plate 601 is pushed to the right, the tension spring 702 is extended. When the annular plate 601 is released, the tension spring 702 is shortened, so that the rotating rod 602 rotates. Figure 3 As shown, the vertical rod of the limiting block 703 is pressed against one side of the fixed rod 5, so that the rotating rod 602 stops rotating. At this time, the piglet trunk is limited between the annular plate 601 and the Y-shaped frame 1.

[0026] The spring clip 4 includes a fixed plate 401 and a movable plate 402. An arc groove 403 for placing the pig leg is opened on one side of the fixed plate 401 and the movable plate 402. A concave block 404 is welded to one side of the fixed plate 401. A rotating shaft 405 is fixed to the bottom of the movable plate 402. The rotating shaft 405 is rotatably connected in the concave block 404. The outer wall of the rotating shaft 405 is sleeved with a torsion spring 406.

[0027] Press one end of the movable plate 402 to bring the two pins of the torsion spring 406 closer to each other, open the movable plate 402, put the piglet's hind legs into the two arc-shaped grooves 403, release the movable plate 402, and clamp the movable plate 402 above the fixed plate 401 under the elastic force of the torsion spring 406.

[0028] A sponge sleeve 8 is fixed to the outer wall of the V-shaped end of the Y-shaped frame 1 , and a sponge pad 9 is glued to the inner wall of the arc-shaped groove 403 .

[0029] The hanging structure 3 includes a hook 301 , one end of which is U-shaped, and the other end of which is welded to one side of the baffle 2 . Two hooks 301 are provided.

[0030] The hanging structure 3 further includes a U-shaped ring 302 , both ends of which penetrate the baffle 2 and are threadedly connected with nuts 303 .

[0031] When in use, the device is fixed to the pig pen, specifically, the two hooks 301 are hung on the horizontal fence at the top of the pig pen, the baffle 2 is pressed against the vertical rod under the horizontal fence of the pig pen, and the U-shaped ring 302 is inserted, and the U-shaped ring 302 limits the vertical rod in the gap between the U-shaped ring 302 and the baffle 2;

[0032] After the device is fixed, the annular plate 601 is pushed to the right, the tension spring 702 is extended, the piglet's body is placed between the Y-shaped frame 1 and the annular plate 601, and the piglet's face is facing the baffle 2. The annular plate 601 is released, the tension spring 702 is shortened, and the rotating rod 602 rotates. Figure 3 As shown, the vertical rod of the limit block 703 is pressed against one side of the fixed rod 5, so that the rotating rod 602 stops rotating. At this time, the piglet's trunk is limited between the annular plate 601 and the Y-shaped frame 1, and the movable plate 402 is pressed to place the two hind legs of the piglet in the arc groove 403, and the movable plate 402 is released. At this time, the piglet is fixed.

[0033] Compared with the traditional piglet slaughtering rack, the device not only prevents the pig legs from falling off the bottom of the device, but also increases the contact area between the pig legs and the device, thereby avoiding injuries to the piglet legs and improving the castration efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
