Description

Technical Field

[0001] The present invention relates to the technical field of animal husbandry, and more particularly to a weighing device used for sheep breeding. Background Art

[0002] Weighing is a core component of sheep farming management, directly impacting economic returns and animal health. Regular weighing allows for accurate monitoring of sheep growth performance, optimizing feed ratios, and reducing breeding costs. It also helps identify individuals with abnormal weights and prevent disease or malnutrition. High-yielding breeding sheep can be selected to improve breeding efficiency. Furthermore, weight-based pricing during trading or sale ensures fair returns. Furthermore, weighing data provides a basis for scientific decision-making and is a crucial foundation for achieving refined, digitalized farming.

[0003] For scientific feeding, precise management, and disease prevention and control, sheep are typically kept in separate groups to improve breeding efficiency and protect animal health. However, during the weighing process, sheep from different pens must pass through the same weighing equipment one by one. Due to differences in living environment, feeding methods, and immune status among the sheep in each pen, collective weighing can lead to cross-contact between the sheep, creating a high-risk node for virus transmission. Therefore, it is necessary to propose a weighing device for sheep farming to solve this problem. Summary of the Invention

[0004] In response to the problems existing in the prior art, the present invention aims to provide a weighing device for sheep farming that can address the problem of existing sheep weighing equipment not being effectively disinfected during collective weighing, which can lead to virus transmission and cross-infection. The device has the advantage of timely disinfection after each sheep is weighed, preventing the spread of viruses and cross-infection.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A weighing device for sheep farming, comprising a cage, one corner of the cage being rotatably connected to a central axis, a rotating motor being mounted on the top of one corner of the cage, an output end of the rotating motor being mounted on the top of the central axis, two groups of arm beams being symmetrically mounted on the upper and lower surfaces of the central axis, with four arm beams in each group arranged in a cross pattern;

[0007] A strip-shaped inner cavity is provided in the four arm beams at the upper end of the central axis, and a plurality of nozzles are equidistantly installed at the bottom of the four arm beams, and the plurality of nozzles are communicated with the corresponding strip-shaped inner cavities.

[0008] As a preferred solution of the present invention, a sliding door is symmetrically installed at one end of the cage body, a bottom beam is installed at the bottom of the other end of the cage body, an arc corner frame is provided on the top of the cage body, and a slide is provided at the bottom of the arc corner frame.

[0009] As a preferred solution of the present invention, a floor scale is installed inside the cage body, and four weighing feet are symmetrically installed on the top surface of the floor scale. A load-bearing plate is placed on the top of the four weighing feet. One side of the floor scale is rotatably connected to a plurality of sleeves, and the same side of the load-bearing plate is installed with a plurality of sliding rods corresponding to the sleeves, and each of the sliding rods is slidably connected to the corresponding sleeve. Two pull rods are rotatably connected to the other side of the load-bearing plate, and a triangular plate is fixed to the end of the pull rod, and the pull rod and the triangular plate are slidably connected to the inside of the bottom beam.

[0010] As a preferred solution of the present invention, a push plate is installed at the bottom of the central axis, and the push plate is rotatably connected to the inside of the bottom beam.

[0011] As a preferred solution of the present invention, a first spring and a telescopic rod are installed in each of the arm beams at the upper end of the central axis, the telescopic rod is elastically connected to the inside of the arm beam through the first spring, and a plurality of nozzles are equidistantly arranged at the bottom of the telescopic rod, and a convex column is installed on the top surface of the end of the telescopic rod away from the central axis.

[0012] As a preferred solution of the present invention, a liquid tube is installed in the arm beam at the upper end of the central axis, one end of the liquid tube is connected to the strip inner cavity, and the other end of the liquid tube is connected to the interior of the telescopic rod. A squeezing clamp and a second spring are installed in the arm beam at the upper end of the central axis at one end away from the central axis. The squeezing clamp is elastically connected to the interior of the arm beam through the second spring, and one side of the squeezing clamp abuts against the liquid tube, and a plug is fixed on the other side of the squeezing clamp. An arc strip is installed on the side of the telescopic rod, and the plug abuts against the surface of the arc strip.

[0013] As a preferred solution of the present invention, a regulating groove is provided on the side of the bottom beam, a connecting rod is slidably connected to the inside of the bottom beam, a sliding frame is slidably connected to the outside of the connecting rod, a regulating rod is installed on the outside of the sliding frame, and the regulating rod is slidably connected to the regulating groove.

[0014] As a preferred solution of the present invention, a push rod is slidably connected to the inside of the bottom beam, a side slide groove is installed at one end of the push rod, one end of the connecting rod is slidably connected to the inside of the side slide groove, a third spring is installed inside the bottom beam, the push rod is elastically connected to the inside of the bottom beam through the third spring, and two downward pressure blocks are installed at intervals on the top surface of the push rod.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. A rotating cross door is set at one corner of the cage exit. The cross door can close the cage exit. When the exit needs to be opened, the revolving door on the side of the cage can drive away the sheep, preventing them from staying inside the cage, making it easier for the flock to leave the cage and saving weighing time. A strip inner cavity and a nozzle are also set on the cross door. When the cross door rotates, the external pump body pumps the liquid medicine into the strip inner cavity of the arm beam on the side and exit of the cage, and sprays it through the nozzle, covering the fan-shaped area, effectively disinfecting the space where the sheep pass, and reducing the risk of virus transmission.

[0017] 2. The coordination of the dial boss and the slide allows the retractable rod to slide when the revolving door rotates, thereby flexibly adjusting the number of exposed nozzles and the disinfection range, ensuring the disinfection effect of each area inside the cage. The telescopic length of the telescopic rod automatically adjusts with the position of the revolving door. The closer to the diagonal position of the central axis of the cage, the more nozzles are exposed, which compensates for the problem of insufficient nozzle coverage on the arm beam and makes disinfection more comprehensive. At the same time, the design of the arc strip and the extrusion clamp can dynamically control the opening and closing degree of the liquid tube, accurately adjust the flow of the disinfectant solution, reduce the spraying volume in the corners of the cage, and increase the spraying volume in the middle area of the cage side. This ensures effective disinfection while avoiding waste of liquid solution, not only optimizing disinfection efficiency but also reducing breeding costs. In particular, it rationally allocates disinfection resources for the corners of the cage where the sheep are less active, taking into account both economy and practicality.

[0018] 3. The push-to-dial at the bottom of the central axis works in conjunction with the control rod, connecting rod, and push rod, triggering the tilting and drainage function of the load-bearing plate under manual control. When the control rod is moved to the long end of the control slot, the connecting rod contacts the push-to-dial. As the central axis rotates, the push-to-dial pushes the connecting rod, which in turn drives the push rod and the downward pressure block, pressing down the triangular plate and pulling the pull rod. Ultimately, the load-bearing plate tilts to one side to drain accumulated fluid, effectively solving the problem of disinfectant liquid accumulating on the load-bearing plate surface. This ensures both weighing accuracy and the stability of the sheep's walking. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0033] For example 1, please refer to Figures 1 to 11 As shown, the present invention discloses a weighing device for sheep breeding, comprising a cage 11, wherein one corner of the cage 11 is rotatably connected to a central axis 31, a rotating motor 32 is mounted on the top of one corner of the cage 11, and an output end of the rotating motor 32 is mounted on the top of the central axis 31, and two groups of arm beams 33 are symmetrically mounted on the upper and lower surfaces of the central axis 31, with four arm beams 33 in each group arranged in a cross pattern;

[0034] A strip-shaped inner cavity 35 is provided in the four arm beams 33 at the upper end of the central axis 31 , and a plurality of nozzles 36 are equidistantly installed at the bottom of the four arm beams 33 , and the plurality of nozzles 36 are communicated with the corresponding strip-shaped inner cavity 35 .

[0035] A sliding door 12 is symmetrically mounted on one end of the cage body 11 , a bottom beam 13 is mounted on the bottom of the other end of the cage body 11 , an arc-shaped frame 14 is disposed on the top of the cage body 11 , and a slideway 15 is disposed on the bottom of the arc-shaped frame 14 .

[0036] A floor scale 21 is installed inside the cage 11. Four weighing feet 22 are symmetrically installed on the top surface of the floor scale 21. A load-bearing plate 23 is placed on the top of the four weighing feet 22. One side of the floor scale 21 is rotatably connected to a number of sleeves 24. On the same side of the load-bearing plate 23, a number of sliding rods 25 corresponding to the sleeves 24 are installed, and each sliding rod 25 is slidably connected to the corresponding sleeve 24. The other side of the load-bearing plate 23 is rotatably connected to two pull rods 26. A triangular plate 27 is fixed to the end of the pull rod 26, and the pull rod 26 and the triangular plate 27 are slidably connected to the inside of the bottom beam 13.

[0037] A push plate 34 is installed at the bottom of the central shaft 31 , and the push plate 34 is rotatably connected to the inside of the bottom beam 13 .

[0038] The cage 11 is welded with metal rods and has a cubic structure. The side of the cage 11 where the sliding door 12 is installed is the entrance, and the side opposite to the sliding door 12 is the exit. No metal rods are welded to the side of the cage 11 where the central axis 31 is installed and the exit.

[0039] Two groups of arm beams 33 are symmetrically installed at the upper and lower ends of the central axis 31, each group having four arm beams 33. The central axis 31 and all the arm beams 33 together form a rotatable cross door. The upper and lower arm beams 33 on the central axis 31 that are in the same vertical plane are set as a pair. The two arm beams 33 of each pair are connected by a metal rod. The partition formed by each pair of arm beams 33 is defined as a revolving door, and its area is the same as the single-side area of the cage body 11. That is, when the door formed by one pair of arm beams 33 closes the side of the cage body 11, the door formed by the other adjacent pair of arm beams 33 just closes the exit of the cage body 11.

[0040] Before the sheep are weighed, the cross gate formed by the arm beam 33 is in the position shown in the appendix of the specification. Figure 1 When weighing a flock of sheep, the sliding door 12 is first opened, and a sheep enters the cage 11. The sliding door 12 is then closed. A floor scale 21 is installed on the bottom surface of the cage 11. When the sheep stands on the load-bearing plate 23, gravity is transmitted through the weighing feet 22 to measure the weight of the sheep.

[0041] During the weighing process, the sheep stands on the load-bearing plate 23, the weighing foot 22 and the load-bearing plate 23 will drop slightly, and the bottom end of the slide bar 25 in the sleeve 24 does not touch the bottom of the sleeve 24, that is, there is a certain space between the two; similarly, the pull rod 26 can also drop freely inside the bottom beam 13 (cannot rise), so that during the weighing process, the sleeve 24 and the slide bar 25, as well as the pull rod 26 will not affect the movement of the load-bearing plate 23, thereby avoiding affecting the weighing accuracy of the floor scale 21.

[0042] After the measurement is completed, the rotating motor 32 is started, driving the central shaft 31 to rotate, and the central shaft 31 drives the arm beam 33 to rotate. After the arm beam 33 at the exit of the cage body 11 rotates, the exit of the cage body 11 is opened, and the sheep walk out. At the same time, the arm beam 33 on the side of the cage body 11 rotates toward the inside of the cage body 11, reducing the internal space of the cage body 11 and driving the sheep away.

[0043] While the central axis 31 drives the arm beam 33 to rotate, the external water pump pumps disinfectant liquid into the arm beam 33 at the side and outlet of the cage body 11 (the arm beam 33 here is the arm beam 33 installed at the upper end of the central axis 31, the same below). The disinfectant liquid fills the strip inner cavity 35 in the arm beam 33, and then is sprayed out through the nozzle 36 at the bottom of the arm beam 33. The fan-shaped area swept by the arm beam 33 at the side and outlet of the cage body 11 will be sprayed with disinfectant liquid (the fan-shaped area is a quarter circle, that is, when the arm beam 33 on the side of the cage body 11 rotates circumferentially to the outlet, the nozzle 36 stops spraying disinfectant liquid), and the space where the sheep pass is fully disinfected to reduce the risk of virus transmission.

[0044] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 11 A first spring 41 and a telescopic rod 42 are installed in each arm beam 33 at the upper end of the central axis 31. The telescopic rod 42 is elastically connected to the inside of the arm beam 33 through the first spring 41, and a plurality of nozzles 36 are equidistantly arranged at the bottom of the telescopic rod 42. A convex column 43 is installed on the top surface of the end of the telescopic rod 42 away from the central axis 31.

[0045] A liquid tube 51 is installed in the arm beam 33 at the upper end of the central axis 31, one end of the liquid tube 51 is connected to the strip inner cavity 35, and the other end of the liquid tube 51 is connected to the interior of the telescopic rod 42. A squeezing clamp 52 and a second spring 53 are installed in the arm beam 33 at the upper end of the central axis 31 at the end away from the central axis 31. The squeezing clamp 52 is elastically connected to the interior of the arm beam 33 through the second spring 53, and one side of the squeezing clamp 52 contacts the liquid tube 51, and a plug 54 is fixed to the other side of the squeezing clamp 52. An arc strip 55 is installed on the side of the telescopic rod 42, and the plug 54 contacts the surface of the arc strip 55.

[0046] The top surface of the cage 11 is provided with an arc-shaped frame 14, with its ends extending through the side of the top surface and the side beam at the exit of the cage 11. As the cross door rotates toward the interior of the cage 11, when the revolving door outside the cage 11 rotates to close the side of the cage 11, the protruding posts 43 on the top surface of the arm beam 33 of the revolving door simultaneously enter the slideway 15 at the bottom of the arc-shaped frame 14 and continue to slide within the slideway 15 as the cross door continues to rotate.

[0047] As can be seen from Example 1, when the revolving door at the exit of cage 11 rotates toward the outside of cage 11, the exit of cage 11 opens, and the weighed sheep exits through the exit. Simultaneously, the revolving door on the side of cage 11 rotates toward the inside of cage 11. As these two revolving doors rotate, the nozzles 36 at their bottoms spray disinfectant liquid. During this process, as the revolving door on the side of cage 11 rotates toward the inside of cage 11, the boss 43 slides within the slide 15. Under the guidance and restraint of the slide 15, the boss 43 pulls the telescopic rod 42 out of the arm beam 33, and the first spring 41 extends. The length of time the telescopic rod 42 slides out of the arm beam 33 varies with the rotational position of the revolving door about the central axis 31 and the position of the boss 43 within the slideway 15. Generally speaking, as the revolving door rotates from the side of the cage 11 toward the interior, the closer the boss 43 is to the diagonal point opposite the central axis 31 of the cage 11, the greater the length of time the telescopic rod 42 slides out of the arm beam 33, and the more nozzles 36 are exposed at the bottom of the telescopic rod 42. The nozzles 36 at the bottom of the telescopic rod 42 are exposed, where they begin to spray disinfectant, thereby disinfecting the space not covered by the arm beam 33. (The interior of the cage 11 is a cube, and the arm beam 33 covers a quarter of a cylinder. The closer to the diagonal point opposite the central axis 31 of the cage 11, the larger the space uncovered by the arm beam 33, and the less effective the disinfection is, so disinfection of this space is necessary.)

[0048] Because the sheep's range of motion during weighing is limited to the center of the cage 11, the space at the four corners of the cage 11 is rarely involved. From a cost-effective perspective, the disinfection effort in this space can be appropriately reduced. Therefore, the side of the telescopic rod 42 is provided with a curved strip 55 with an inwardly concave arc. The two ends of the curved strip 55 are at the same height. When the telescopic rod 42 is within the arm beam 33, the end of the curved strip 55 away from the central axis 31 contacts the top 54, causing the squeeze pliers 52 to compress the second spring 53 and squeeze the liquid passage 51. The function of the liquid passage 51 is to introduce the disinfectant solution in the curved strip 55 into the telescopic rod 42, and ultimately spray it out from the nozzle 36 at the bottom of the telescopic rod 42. After the squeeze pliers 52 squeeze the liquid passage 51, the passage is closed, and the disinfectant solution in the strip inner cavity 35 does not enter the telescopic rod 42.

[0049] As the arm 33 rotates toward the diagonal position of the central axis 31 within the cage 11, the curved bar 55 gradually slides out of the arm 33, following the telescopic rod 42. When the diagonal of the arm 33 and the cage 11 coincide, the plug 54 moves from the end of the curved bar 55 away from the central axis 31 to the other end of the curved bar 55. During this process, the curved bar 55 gradually releases the squeeze jaws 52 until it squeezes the plug 54 and squeeze jaws 52 again, causing the passage of the liquid passage 51 to gradually expand to its maximum value, then gradually shrink until it is resealed. The arm 33 then continues to rotate toward the exit of the cage 11. Under the restraining action of the slideway 15, the telescopic rod 42 and curved bar 55 gradually retract into the arm 33. The change in the size of the liquid passage 51 can adjust the amount of disinfectant liquid in the strip inner cavity 35 that enters the interior of the telescopic rod 42, thereby controlling the amount of liquid sprayed by the nozzle 36 at the bottom of the telescopic rod 42. Therefore, during the entire change process of the arc-shaped strip 55, the adjustment of the liquid spraying amount of the nozzle 36 at the bottom of the telescopic rod 42 is well achieved, from gradually decreasing the amount of liquid sprayed at the corner of the cage body 11 to gradually increasing the amount of liquid sprayed at the middle position of the side of the cage body 11, thereby achieving the disinfection effect while greatly reducing the waste of disinfectant liquid and effectively reducing the cost of sheep breeding.

[0050] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 11 A regulating groove 61 is provided on the side of the bottom beam 13, a connecting rod 62 is slidably connected inside the bottom beam 13, a sliding sleeve frame 63 is slidably connected to the outside of the connecting rod 62, a regulating rod 64 is installed on the outside of the sliding sleeve frame 63, and the regulating rod 64 is slidably connected to the regulating groove 61.

[0051] A push rod 71 is slidably connected to the inside of the bottom beam 13, and a side slide groove 72 is installed at one end of the push rod 71. One end of the connecting rod 62 is slidably connected to the inside of the side slide groove 72. A third spring 73 is installed inside the bottom beam 13. The push rod 71 is elastically connected to the inside of the bottom beam 13 through the third spring 73. Two downward pressure blocks 74 are installed at intervals on the top surface of the push rod 71.

[0052] Each time a sheep enters the cage 11 for weighing, it is sprayed with disinfectant. If this spraying continues for a long time, the disinfectant will eventually land on the surface of the load-bearing plate 23, potentially causing the disinfectant to accumulate. This can cause the weight of the load-bearing plate 23 to change, affecting the accuracy of the weighing on the scale 21, and can also make the surface of the load-bearing plate 23 slippery, affecting the stability of the sheep's walking. Therefore, a push-disc 34 is provided at the bottom of the central axis 31. When the central axis 31 rotates, the push-disc 34 idles inside the bottom beam 13. In the initial state, the control rod 64 is located at the short end of the control slot 61 (the control slot 61 is L-shaped, with the long side of the "L" as the long end and the short side as the short end). At this point, restricted by the control slot 61, the control rod 64 drives the connecting rod 62 through the sliding sleeve 63 to be above the push-disc 34, without interfering with the push-disc 34.

[0053] After a certain period of time, manually move the control lever 64 and follow the instructions. Figure 1 As shown, the regulating rod 64 is first moved to the left and then downward. First, the regulating rod 64 drives the sliding sleeve 63 to slide to the left on the surface of the connecting rod 62, and then the sliding sleeve 63 drives the connecting rod 62 to slide downward. When the regulating rod 64 reaches the long end of the regulating groove 61, one end of the connecting rod 62 slides from the upper end of the side slide groove 72 to the bottom, and the other end of the connecting rod 62 contacts the side of the push plate 34. Then, during the rotation of the central axis 31, the push plate 34 is driven to rotate, and the push plate 34 pushes the connecting rod 62 to the right. The connecting rod 62 slides relative to the sliding sleeve 63 and pushes the push rod 71 to the right through the side sliding groove 72 to slide inside the bottom beam 13. The push rod 71 compresses the third spring 73 and drives the two lower pressure blocks 74 to slide to the right. During the sliding process of the lower pressure block 74, the corresponding triangular plate 27 is squeezed, causing the triangular plate 27 to slide downward, and the triangular plate 27 drives the corresponding pull rod 26 to slide toward the inside of the bottom beam 13. Because the top of the pull rod 26 is connected to the side of the load-bearing plate 23 for rotation, the pulling force of the pull rod 26 causes the load-bearing plate 23 to tilt downward on this side, that is, the load-bearing plate 23 tilts downward to the side where the bottom beam 13 is located with the two weighing feet 22 close to the bottom beam 13 as the fulcrum. After tilting, the accumulated liquid on the top surface of the load-bearing plate 23 will be discharged from the top surface of the load-bearing plate 23, thereby recalibrating the weight of the load-bearing plate 23.

[0054] During the tilting process of the load-bearing plate 23, the slide bar 25 on the other side thereof slides out of the corresponding sleeve 24 (the two do not disengage), and the sleeve 24 tilts with the floor scale 21. The sleeve 24 and the slide bar 25 are used to prevent the load-bearing plate 23 from sliding or shifting during the tilting process, thereby ensuring that the load-bearing plate 23 can return to its original position.

[0055] After the central axis 31 rotates 90 degrees, each structure inside the bottom beam 13 will be reset, so that the load-bearing plate 23 is placed horizontally on the top of the weighing foot 22 again.

[0056] After drainage is completed, the regulating rod 64 is pushed upward to return the regulating rod 64 to the short end of the regulating groove 61, and the connecting rod 62 is lifted again above the push plate 34 by the sliding sleeve 63 to ensure that the rotation of the push plate 34 does not cause the connecting rod 62 to slide horizontally.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
