Description

Technical Field

[0001] This utility model relates to a weighing and transferring device, specifically a weighing and transferring device for cattle, belonging to the technical field of livestock breeding equipment. Background Technology

[0002] Livestock farming equipment refers to various instruments and facilities used in the breeding, management, and production of livestock and poultry. It covers equipment for feeding, environmental control, and disease prevention and control. In the daily management of cattle herds, such as regularly monitoring weight to adjust feed ratios, and when cattle are sold or transported, accurate weighing and pricing and safe transportation are required. In disease prevention and control, in cases where sick cattle are isolated and weighed for accurate medication, cattle weighing and transportation devices can play a role in weighing, measurement, and convenient transportation, thereby improving breeding efficiency and management level.

[0003] The existing utility model with authorization announcement number CN221615882U discloses a weighing and transferring device for cattle. The presence of movable wheels allows the device to move on the ground, making it convenient to move the device to different positions for subsequent weighing work. The movable wheels rotate through bearings, providing support to the ground and ensuring that the device can roll smoothly during movement, reducing friction and making the device easier to control. The two pairs of movable wheels can work independently to facilitate turning in place and adjusting direction. The cattle pen provides a relatively safe, comfortable, and controlled environment, which helps reduce cattle stress and potential injury, and restricts the cattle's range of movement. The body restraint bladder inside the cattle pen can be inflated to further restrict the cattle's range of movement within the device, ensuring that they will not be injured or escape during movement or weighing.

[0004] While the aforementioned technical solution enables multi-directional transport and provides good spatial restraint for cattle, its chassis is too high and cannot be adjusted. The lack of an adjustable chassis height makes it difficult for smaller or less mobile cattle to load and unload, increasing the difficulty of loading and unloading. Therefore, a weighing and transporting device for cattle is proposed here. Utility Model Content

[0005] This invention proposes a weighing and transfer device for cattle to solve the problem that the lack of an adjustable chassis height travel structure in the prior art makes it difficult for small or immobile cattle to get on and off the device, thus increasing the difficulty of loading and unloading cattle.

[0006] This utility model is achieved through the following technical solution: a weighing and transfer device for cattle, including a cattle pen frame, a weighing plate is fixedly connected to the inner bottom wall of the cattle pen frame, two protective doors are movably hinged to the back of the cattle pen frame, and a chassis adjustment mechanism is provided on the outer side of the cattle pen frame. The chassis adjustment mechanism includes four fixed housings. A servo motor is fixedly connected to the inner wall of each fixed housing. A lifting column is slidably connected inside each fixed housing. A threaded rod is fixedly connected to the output end of each servo motor. A high-strength universal wheel is fixedly connected to the bottom end of each lifting column. A nut sleeve is fixedly connected to the inner wall of each lifting column. A button controller is fixedly connected to the front of the cattle rack. The weighbridge plate and the four servo motors are electrically connected to the button controller via wires.

[0007] Specifically, the two protective doors are respectively in contact with the two sides of the cattle pen frame on their respective sides. The side of each fixed shell close to the cattle pen frame is fixedly connected to the outer surface of the cattle pen frame. The inner wall of each nut sleeve is threadedly connected to the outer surface of the threaded rod. Two fixed rods are fixedly connected to the front of the cattle pen frame. A limit rod is fixedly connected to the front of each protective door.

[0008] Furthermore, each of the fixed rods has a limit block rotatably connected to its outer surface, and the interior of each limit block is engaged with the outer surface of the limit rod.

[0009] Each of the lifting columns has two limiting sliders fixedly connected to its outer surface, and the outer surface of each limiting slider is slidably connected to the inside of the fixed shell.

[0010] Preferably, a coupling is fixedly connected to the outer surface of the output end of each servo motor, and the inner wall of each coupling is fixedly connected to the outer surface of the threaded rod.

[0011] Furthermore, an auxiliary bearing is fixedly connected to the inner wall of each of the fixed shells, and the inner ring of each auxiliary bearing is fixedly connected to the outer surface of the threaded rod.

[0012] This utility model provides a weighing and transferring device for cattle, which has the following beneficial effects: This cattle weighing and transfer device, through the coordinated operation of a cattle pen frame, a weighbridge, a protective door, a fixed shell, servo motors, threaded rods, lifting columns, high-strength casters, a nut sleeve, and a button controller, allows for real-time weighing of cattle standing inside the pen frame and protective door. The button controller simultaneously powers four servo motors, rotating the threaded rods, which in turn raises and lowers the four high-strength casters relative to the pen frame. When cattle are being loaded or unloaded, the casters are raised to a position where they are not in contact with the ground, while the pen frame remains in contact with the ground. When cattle need to be transferred, the button controller lowers all four casters simultaneously, ensuring they support the ground while the pen frame remains off the ground. This significantly improves the convenience of loading and transferring cattle, avoiding the problem of small or immobile cattle being difficult to load and unload due to the lack of an adjustable chassis height.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] Please see Figures 1-4This utility model provides a weighing and transfer device for cattle, including a cattle pen 1. A weighbridge plate 2 is fixedly connected to the inner bottom wall of the cattle pen 1. The weighbridge plate 2 is a mature existing weighbridge structure with a good anti-slip effect on its upper surface. It can be customized according to the size of the cattle pen 1 for specific use, and can weigh the cattle immediately after they enter the cattle pen 1. Two protective doors 3 are movably hinged to the back of the cattle pen 1. A chassis adjustment mechanism 4 is provided on the outer side of the cattle pen 1. The chassis adjustment mechanism 4 includes four fixed shells 401, and a servo is fixedly connected to the inner wall of each fixed shell 401. The servo motor 402 has a built-in angle encoder, which can cooperate with other control structures to rotate accurately in terms of the number of revolutions and angles. The two protective doors 3 are close to each other on one side and respectively contact the two sides of the cattle pen frame 1. The side of each fixed shell 401 close to the cattle pen frame 1 is fixedly connected to the outer surface of the cattle pen frame 1. Two fixed rods 5 are fixedly connected to the front of the cattle pen frame 1. Each protective door 3 is fixedly connected to the front of the limit rod 6. By setting the fixed rods 5, a rotation base surface can be provided for other limit structures. By setting the limit rods 6, the above limit structures can be limited.

[0017] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 Each fixed housing 401 has a sliding connection to a lifting column 404 inside, and each servo motor 402 has a fixed connection to a threaded rod 403 at its output end. Each fixed rod 5 has a rotatable connection to a limit block 7 on its outer surface. The interior of each limit block 7 is engaged with the outer surface of the limit rod 6. By setting the limit block 7, it can rotate around the outer surface of the fixed rod 5 and engage with the outer surface of the limit rod 6, thereby temporarily locking the relative position of the protective door 3 and the cattle pen frame 1.

[0018] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 Each lifting column 404 has a high-strength universal wheel 405 fixedly connected to its bottom end. The high-strength universal wheel 405 has a high load-bearing capacity and can move in multiple directions. Each lifting column 404 has a nut sleeve 406 fixedly connected to its inner wall. The inner wall of each nut sleeve 406 is threaded to the outer surface of the threaded rod 403. Each lifting column 404 has two limiting sliders 10 fixedly connected to its outer surface. The outer surface of each limiting slider 10 is slidably connected to the inside of the fixed shell 401. By setting the limiting sliders 10, the lifting column 404 can slide vertically and directionally inside the fixed shell 401, thereby increasing the orientation and stability of the lifting column 404 relative to the fixed shell 401.

[0019] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 A button controller 407 is fixedly connected to the front of the cow rack 1. The button controller 407 can be an MCU or an Arduino series, which is small in size, low in cost and low in power consumption, and suitable for miniaturization and embedded applications. It can control multiple components through programming. It can be connected to the control terminal of each electrical component through digital output pins and control the power of each component through analog output pins. Specific control logic and timing can be implemented by writing code. The button controller 407 has a display screen, which can enable the weighing function of the weighbridge 2 and display the weighing result of the weighbridge 2. It can also preset and control the number of rotations and angles of the four servo motors 402, and thus synchronously control the lifting height of the four high-strength universal wheels 405 relative to the cow rack 1. The outer surface of the output end of each servo motor 402 is fixedly connected to a coupling 8. The inner wall of each coupling 8 is fixedly connected to the outer surface of the threaded rod 403. By setting the coupling 8, the connection between the output end of the servo motor 402 and the threaded rod 403 can be strengthened, thereby increasing the rotational stability of the threaded rod 403.

[0020] Please refer to this carefully. Figure 3 The weighbridge plate 2 and the four servo motors 402 are electrically connected to the button controller 407 via wires. Each fixed shell 401 has an auxiliary bearing 9 fixedly connected to its inner wall. The inner ring of each auxiliary bearing 9 is fixedly connected to the outer surface of the threaded rod 403. By setting the auxiliary bearing 9, the fixed shell 401 and the threaded rod 403 can be connected, thereby increasing the smoothness of the rotation of the threaded rod 403.

[0021] When using this utility model: First, while the high-strength casters 405 are supporting the ground, push the entire device to a location where it is convenient for cattle to climb. Then, operate the button controller 407 to control the four high-strength casters 405 to rise until the bottom of the cattle pen frame 1 contacts and supports the ground.

[0022] Then, the guard door 3 on one side is opened manually, and the cattle are driven into the cattle pen 1. The weight signal is transmitted to the button controller 407 via a wire and then displayed on the display screen of the button controller 407. After that, the guard door 3 that was opened is closed.

[0023] When the cattle are loaded and need to be transferred using this device, the operator controls the four high-strength casters 405 to descend synchronously until all four casters 405 are in contact with the ground for support. This solves the loading and unloading difficulties caused by the non-adjustable chassis of traditional devices, improving the convenience of transfer. The design of the entire cattle load-bearing and transfer device effectively solves the problem that the lack of a height-adjustable chassis structure makes it difficult for small or immobile cattle to get on and off the device, thus increasing the difficulty of loading and unloading cattle.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
