Description

Technical Field

[0001] This utility model relates to the field of livestock hoof trimming technology, and in particular to a hoof trimming device for sows. Background Technology

[0002] In large-scale pig farming, the health of sows' limbs and hooves is a key factor affecting their reproductive performance and lifespan. Due to prolonged exposure to hard surfaces such as gestation crates, sows often experience insufficient activity, leading to excessive hoof growth or uneven wear. This can result in various limb and hoof diseases such as hoof cracks and foot inflammation, which can severely cause lameness, difficulty feeding, and even culling. Therefore, regular hoof trimming of sows is an important daily management practice to ensure their health and welfare and extend their productive lifespan.

[0003] Currently, hoof trimming of sows typically utilizes existing gestation or restraint crates to restrict the sow's body position. While the sow's torso is confined by the bars, her limbs still have a considerable range of motion. The operator needs to grasp and lift one of the sow's hooves by hand or with the aid of simple ropes, and try to hold it in a suitable position and angle. Throughout the hoof trimming process, the operator usually needs to expend considerable physical strength to control the sow's leg struggles while simultaneously operating the trimming tools with their other hand, requiring a high degree of coordination and strength.

[0004] However, the traditional method of manually restraining pig hooves has inherent safety and efficiency problems. Due to the lack of a dedicated and effective restraint and fixation mechanism for individual hooves, sows will struggle and kick violently during hoof trimming due to stress. This not only greatly increases the difficulty and danger of the operation—operators are easily injured by kicks or lose their grip due to the sow's sudden exertion—but the sow herself may also suffer joint or soft tissue injuries from excessive struggling. Furthermore, because the hoof cannot be stably fixed in one position, operators cannot perform precise and accurate trimming, resulting in inconsistent hoof trimming quality. The process is time-consuming and inefficient, making it difficult to effectively and safely promote this necessary health management measure. Therefore, a sow hoof trimming device is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hoof trimming device for sows, aiming to improve upon the traditional method of manually restraining pig hooves, which lacks an effective fixing mechanism, causing sows to struggle violently due to stress. This not only increases the difficulty of operation and personal danger but may also injure the sow herself. Furthermore, unstable hooves make trimming inaccurate, resulting in time-consuming and poor-quality work.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hoof trimming device for sows, comprising a cage body, wherein a first side frame and a second side frame are fixedly connected to the upper surface of the cage body, the first side frame and the second side frame form a fully enclosed frame, a second side plate is provided on the inner side of the first side frame, an opening is provided through the inside of the side plate, a positioning mechanism is installed on the outer wall of the side plate, and a hoof trimming mechanism is installed on one side of the outer wall of the side plate;

[0007] The positioning mechanism includes a bracket, a limiting rod, and an arc-shaped plate. One side of the outer wall of the bracket is fixedly connected to one side of the outer wall of the side plate. The outer wall of the limiting rod is slidably connected to the inside of the bracket. The lower end of the limiting rod is fixedly connected to the upper surface of the arc-shaped plate. A rubber block is fixedly connected to the inner side wall of the arc-shaped plate. A spring is sleeved on the outer wall of the limiting rod. A limiting frame is fixedly connected to the outer wall of the side plate. A limiting wheel is rotatably connected inside the limiting frame. The limiting wheel is rolled on one outer wall of the side frame.

[0008] As a further description of the above technical solution:

[0009] The hoof trimming mechanism includes a mounting frame and a hoof trimming cutter. A slider is fixedly connected to one side of the outer wall of the mounting frame. The outer wall of the slider is slidably connected to the inside of the side plate. The hoof trimming cutter is disposed on the upper side of the mounting frame and is fixed to the mounting frame by bolts.

[0010] As a further description of the above technical solution:

[0011] A telescopic rod is fixedly connected to the upper surface of the cage, and a perforated plate is fixedly connected to the upper surface of the telescopic rod.

[0012] As a further description of the above technical solution:

[0013] The cage body has symmetrical limiting grooves inside, and symmetrical sliders are slidably connected inside the cage body.

[0014] As a further description of the above technical solution:

[0015] The two sliders are internally connected to rollers, and one side of each roller is rolled on the inner wall of the limiting groove.

[0016] As a further description of the above technical solution:

[0017] The upper surface of the second slider is fixedly connected to a sliding sleeve, and the two sliding sleeves are internally threaded with a bidirectional lead screw, the two ends of which are rotatably connected to the upper side of the cage.

[0018] As a further description of the above technical solution:

[0019] A rotating plate is rotatably connected to the upper surface of the sliding sleeve, and one side of the rotating plate is rotatably connected to the lower surface of the hollow plate.

[0020] As a further description of the above technical solution:

[0021] The arc-shaped plate is located on one side of the opening, and the hoof trimmer is located on the outer side of the side plate near the opening.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by placing the sow inside the cage and placing the pig's hooves through the opening on the outside of the side frame, the position can be adjusted according to different usage needs by moving the side plate. Then, the reaction force of the spring drives the limiting rod to lower the arc plate, thereby achieving the effect of limiting the position of the pig's hooves. At the same time, the hoof trimming operation can be realized by driving the hoof trimming mechanism. This solves the problem that the traditional device cannot limit the adjustment of the sow's hooves, resulting in a cumbersome and complicated hoof trimming operation, thus improving the practicality of the device.

[0024] 2. In this utility model, by rotating the bidirectional lead screw, the sliding sleeve causes the second slider to slide inside the limiting groove, thereby enabling the roller to move on the inner wall of the limiting groove. This reduces the friction between the second slider and the limiting groove. Simultaneously, the movement of the sliding sleeve causes the rotating plate to rotate, thereby enabling the hollow plate to drive the telescopic rod to extend, limit, lift, and move. This solves the problem that existing devices cannot be adjusted according to different sow sizes, thus improving the practicality of the device. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a sow hoof trimming device, including a cage 1 for overall positioning of the sow. The upper surface of the cage 1 is fixedly connected with a side frame 1 2 and a side frame 2 3 arranged symmetrically on the left and right. The side frame 1 2 and the side frame 2 3 together form an upper fully enclosed frame structure. The inner side of the side frame 1 2 is provided with a side plate 4 that can move left and right to adjust the internal width. The side plate 4 has an opening 5 through which the sow's hoof extends. The outer wall of the side plate 4 is equipped with a positioning mechanism for fixing the hoof. A hoof trimming mechanism for performing trimming operations is also installed on one side of the outer wall of the side plate 4.

[0033] The positioning mechanism includes a bracket 7 serving as a fixed base, a vertically sliding limiting rod 8, and an arc-shaped plate 10 that acts directly on the pig's hoof. One side of the outer wall of the bracket 7 is fixedly connected to one side of the outer wall of the side plate 4, providing an installation base point for the positioning mechanism. The outer wall of the limiting rod 8 can slide inside the bracket 7. The lower end of the limiting rod 8 is fixedly connected to the upper surface of the arc-shaped plate 10 to drive the arc-shaped plate 10 to rise and fall synchronously. The inner side wall of the arc-shaped plate 10 is fixedly connected to a rubber block 12 for buffering and increasing friction. The outer wall of the limiting rod 8 is fitted with a spring 9 for providing continuous downward pressure. The outer wall of the side plate 4 is fixedly connected to a limiting frame 11 for supporting and guiding the movement of the side plate 4. The limiting frame 11 is rotatably connected to a limiting wheel 6 that serves as a guide. The limiting wheel 6 can roll on the outer wall of the side frame 2 to reduce the frictional resistance when the side plate 4 moves.

[0034] Specifically, firstly, by moving the side plate 4 and utilizing the rolling of the limiting wheel 6 on the side frame 2, the internal width of the cage 1 can be easily adjusted to accommodate sows of different sizes, achieving initial restriction of the sow's torso. During hoof trimming, the hoof to be trimmed is guided through the opening 5 on the side plate 4. At this time, the limiting rod 8 is lifted upwards to compress the spring 9. After the hoof is placed in position, the limiting rod 8 is released, and the spring 9 immediately releases its elastic force, driving the limiting rod 8 and the bottom arc plate 10 to automatically descend. The rubber block 12 on the inner side of the arc plate 10 stably presses and fixes the hoof to the outer side of the side plate 4.

[0035] Reference Figure 1 and Figure 2 The hoof trimming mechanism includes a mounting frame 14 and a hoof trimming cutter 15. A slider 13 is fixedly connected to one side of the outer wall of the mounting frame 14. The outer wall of the slider 13 is slidably connected to the inside of the side plate 4. The hoof trimming cutter 15 is set on the upper side of the mounting frame 14 and is fixed to the mounting frame 14 by bolts 16. An arc plate 10 is set on one side of the opening 5, and the hoof trimming cutter 15 is set on the outer side of the side plate 4 near the opening 5.

[0036] Specifically, firstly, by moving the side plate 4 and utilizing the rolling of the limiting wheel 6 on the side frame 2, the internal width of the cage 1 can be easily adjusted to accommodate sows of different sizes, achieving initial restriction of the sow's torso. During hoof trimming, the hoof to be trimmed is guided through the opening 5 on the side plate 4. At this time, the limiting rod 8 is lifted upwards to compress the spring 9. After the hoof is placed in position, the limiting rod 8 is released, and the spring 9 immediately releases its elastic force, driving the limiting rod 8 and the bottom arc plate 10 to automatically descend. The rubber block 12 on the inner side of the arc plate 10 stably presses and fixes the hoof to the outer side of the side plate 4.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The cage body 1 has a telescopic rod 17 fixedly connected to its upper surface for support, and a perforated plate 18 serving as the upper frame is fixedly connected to the upper surface of the telescopic rod 17. The cage body 1 has left and right symmetrical limiting grooves 24 inside, and two sliders 21 serving as the lower moving base are slidably connected inside the cage body 1. Rollers 22 for reducing sliding friction are rotatably connected inside the two sliders 21, and one side of the rollers 22 rolls in the inner wall of the limiting grooves 24. Sliding sleeves 20 are fixedly connected to the upper surface of the sliders 21, and the internal threads of the two sliding sleeves 20 are connected to a double-ended screw 19 with reverse threads. The two ends of the double-ended screw 19 are rotatably connected to the upper side of the cage body 1. A rotating plate 23 serving as a movable sidewall is rotatably connected to the upper surface of the sliding sleeves 20, and one side of the rotating plate 23 is rotatably connected to the lower surface of the perforated plate 18, forming a linkage structure.

[0038] Specifically, when the operator rotates the bidirectional lead screw 19, the reverse thread on it drives the two sliding sleeves 20 and the fixed slider 21 to move synchronously towards or away from each other. Since the slider 21 drives the lower end of the rotating plate 23 to translate along the limiting groove 24, while the upper end of the rotating plate 23 rotates around the fixed hollow plate 18, the entire rotating plate 23 will rotate.

[0039] Working principle: When using this hoof trimming device to trim the hooves of sows, the sow is first placed on the perforated plate 18 inside the cage 1. Side frames 2 and 3 work together to prevent the sow from escaping. Then, the sow's hoof is placed on one side of the hoof trimming blade 15 by passing it through the opening 5. Rotating the double-acting screw 19 moves the two sliding sleeves 20 in opposite directions. The movement of the sliding sleeves 20 causes the rotating plate 23 to rotate, which in turn pushes the perforated plate 18 to rise and fall stably under the limiting extension and retraction of the telescopic rod 17. This allows the sow's hoof to be brought closer to the underside of the rubber block 12. The effect is that while the sliding sleeve 20 moves, the slider 21 drives the roller 22 to move smoothly in the limiting groove 24. When the sow's hoof reaches the lower side of the rubber block 12, the reaction force of the spring 9 drives the limiting rod 8 to push the arc plate 10 down, so that the rubber block 12 abuts against the hoof for limiting. At this time, by pushing the mounting bracket 14, the slider 13 slides inside the side plate 4, which can drive the hoof trimming knife 15 to contact the hoof and achieve the trimming operation. At the same time, the old hoof trimming knife 15 can be replaced and disassembled by using tools to tighten the bolt 16.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
