Description

Technical Field

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

[0002] Weighing is a core link in sheep breeding management, directly affecting economic benefits and animal health. By weighing regularly, the growth performance of sheep can be accurately monitored, the feed ratio can be optimized, and the breeding cost can be reduced; individuals with abnormal body weights can be detected in time to prevent diseases or malnutrition; high-yield breeding sheep can be screened to improve breeding efficiency; at the same time, when trading or selling, the price is calculated according to the weight, ensuring fair returns. In addition, weighing data provides a basis for scientific decision-making and is an important foundation for realizing refined and digital breeding.

[0003] In order to scientifically raise, precisely manage, and prevent the spread of diseases, sheep flocks usually need to be housed in separate pens to improve breeding efficiency and ensure animal health. However, in the weighing process, sheep from different pens need to pass through the same weighing device in sequence. Due to differences in the living environment, feeding methods, and immune status of each pen of sheep, group weighing may lead to cross-contact between sheep flocks and become a high-risk node for virus transmission. Therefore, it is necessary to propose a weighing device for sheep breeding to solve the above problems. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a weighing device for sheep breeding, which can solve the problem that the existing weighing device in sheep breeding does not perform effective disinfection during group weighing, may lead to virus transmission, and cause cross-infection.

[0007] As a preferred embodiment of the present invention, a weighing scale is installed inside the cage body. Four weighing feet are symmetrically installed on the top surface of the weighing scale. A bearing plate is placed on the tops of the four weighing feet. A number of sleeves are rotatably connected to one side of the weighing scale. A number of sliding rods corresponding to the sleeves one by one are installed on the same side of the bearing plate. And each sliding rod is slidably connected inside the corresponding sleeve. Two pull rods are rotatably connected to the other side of the bearing plate. A triangular plate is fixed to the end of the pull rod. And the pull rod and the triangular plate are slidably connected inside the bottom beam.

[0008] As a preferred embodiment of the present invention, a push-dial is installed at the bottom of the central shaft. And the push-dial is rotatably connected inside the bottom beam.

[0009] As a preferred embodiment of the present invention, a first spring and a telescopic rod are installed in each arm beam at the upper end of the central shaft. The telescopic rod is elastically connected inside the arm beam through the first spring. And a number of nozzles are equidistantly arranged at the bottom of the telescopic rod. A convex column is installed on the top surface of the end of the telescopic rod away from the central shaft.

[0010] As a preferred embodiment of the present invention, a liquid delivery pipe is installed in the arm beam at the upper end of the central shaft. One end of the liquid delivery pipe is communicated with the strip-shaped inner cavity. The other end of the liquid delivery pipe is communicated with the inside of the telescopic rod. An extrusion clamp and a second spring are installed inside the arm beam at the upper end of the central shaft away from the central shaft. The extrusion clamp is elastically connected inside the arm beam through the second spring. And one side of the extrusion clamp abuts against the liquid delivery pipe. A top head is fixed to the other side of the extrusion clamp. An arc-shaped strip is installed on the side surface of the telescopic rod. The top head abuts against the surface of the arc-shaped strip.

[0011] As a preferred embodiment of the present invention, a regulation groove is provided on the side surface of the bottom beam. A connecting rod is slidably connected inside the bottom beam. A sliding sleeve frame is slidably connected to the outside of the connecting rod. A regulation rod is installed on the outside of the sliding sleeve frame. And the regulation rod is slidably connected inside the regulation groove.

[0012] As a preferred embodiment of the present invention, a push rod is slidably connected inside the bottom beam. A side sliding groove is installed at one end of the push rod. One end of the connecting rod is slidably connected inside the side sliding groove. A third spring is installed inside the bottom beam. The push rod is elastically connected inside the bottom beam through the third spring. Two pressing blocks are installed at intervals on the top surface of the push rod.

[0013] Compared with the prior art, the advantages of the present invention are as follows: 1. A rotatable cross gate is provided at a corner of the cage outlet. The cross gate can close the cage outlet. When the outlet needs to be opened, the rotating gate on the side of the cage can drive the sheep away, preventing the sheep from staying inside the cage and making it easier for the flock to leave the cage, saving weighing time. A strip-shaped inner cavity and nozzles are also provided on the cross gate. During the rotation of the cross gate, the external pump pumps the liquid medicine into the strip-shaped inner cavity of the arm beam on the side and at the outlet of the cage, and sprays it through the nozzles to cover a fan-shaped area, effectively disinfecting the space where the sheep pass through and reducing the risk of virus transmission.

[0014] 2. The cooperation of the through-pushing convex column and the slideway enables the rotating gate to drive the telescopic rod to slide when rotating, thereby flexibly adjusting the exposure quantity of the nozzles and the disinfection range, ensuring the disinfection effect of each area inside the cage. The telescopic length of the telescopic rod is automatically adjusted according to the position of the rotating gate. The closer to the diagonal position of the middle axis inside the cage, the more nozzles are exposed, compensating for the insufficient coverage of the nozzles on the arm beam and making the disinfection more comprehensive. At the same time, the design of the arc-shaped strip and the extrusion pliers can dynamically control the opening and closing degree of the liquid delivery pipe, accurately adjusting the flow rate of the disinfection liquid medicine, reducing the spraying amount at the corners of the cage and increasing the spraying amount in the middle area on the side of the cage, which not only ensures effective disinfection but also avoids waste of the liquid medicine, optimizing the disinfection efficiency and reducing the breeding cost. Especially for the corner areas where the sheep move less inside the cage, the disinfection resources are reasonably allocated, taking into account both economy and practicality.

[0015] 3. The push-dial plate at the bottom of the central axis cooperates with linkage mechanisms such as the control rod, connecting rod, and push rod. Under manual control, the tilting drainage function of the load-bearing plate can be triggered. When the control rod is toggled to the long end of the control groove, the connecting rod contacts the push-dial plate. As the central axis rotates, the push-dial plate pushes the connecting rod, which in turn drives the push rod and the lower pressing block to move, pressing down the triangular plate and pulling the pull rod, finally tilting the load-bearing plate to one side to drain the accumulated liquid, effectively solving the problem of the accumulation of disinfection liquid medicine on the surface of the load-bearing plate, ensuring both the accuracy of weighing and the stability of the sheep's walking.

Specific implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0019] Example 1, please refer to Figures 1 to 11 As shown, the present invention discloses a weighing device for sheep breeding, including a cage body 11. One corner of the cage body 11 is rotatably connected to a central axis 31. A rotating motor 32 is installed at the top of one corner of the cage body 11. The output end of the rotating motor 32 is installed at the top end of the central axis 31. Two groups of arm beams 33 are symmetrically installed on the surfaces of the upper and lower ends of the central axis 31. Each group of four arm beams 33 is distributed in a cross shape; There is a strip-shaped inner cavity 35 in the four arm beams 33 at the upper end of the central axis 31, and a number of nozzles 36 are equidistantly installed at the bottom of the four arm beams 33, and the number of nozzles 36 communicates with the corresponding strip-shaped inner cavity 35.

[0020] One end of the cage body 11 is symmetrically installed with a sliding door 12. A bottom beam 13 is installed at the bottom of the other end of the cage body 11. An arc angle frame 14 is arranged at the top of the cage body 11, and a slideway 15 is provided at the bottom of the arc angle frame 14.

[0021] A weighing scale 21 is installed inside the cage body 11. Four weighing feet 22 are symmetrically installed on the top surface of the weighing scale 21. A bearing plate 23 is placed on the tops of the four weighing feet 22. A number of sleeves 24 are rotatably connected to one side of the weighing scale 21. A number of slide bars 25 corresponding to the sleeves 24 one by one are installed on the same side of the bearing plate 23, and each slide bar 25 is slidably connected inside the corresponding sleeve 24. Two pull rods 26 are rotatably connected to the other side of the bearing plate 23. A triangular plate 27 is fixed at the end of the pull rod 26, and the pull rod 26 and the triangular plate 27 are slidably connected inside the bottom beam 13.

[0022] A push and pull disk 34 is installed at the bottom of the central axis 31, and the push and pull disk 34 is rotatably connected inside the bottom beam 13.

[0023] The whole body of the cage body 11 is welded by metal rods and is in a cube structure. The side of the cage body 11 where the sliding door 12 is installed is the entrance, and the side opposite to the sliding door 12 is the exit. And the side of the cage body 11 where the central axis 31 is installed and the exit are not welded with metal rods.

[0024] Two groups of arm beams 33 are symmetrically installed at the upper and lower ends of the central axis 31. Each group has four arm beams 33. The central axis 31 and all the arm beams 33 together form a rotatable cross door. Let the upper and lower two arm beams 33 on the central axis 31 in the same vertical plane be a pair. The two arm beams 33 in 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-sided 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.

[0025] Before weighing the sheep flock, the cross door formed by the arm beams 33 is in the position as shown in the attached Figure 1 When weighing the sheep flock, first open the sliding door 12. A sheep enters the inside of the cage body 11, and then close the sliding door 12. A weighing scale 21 is installed on the bottom surface inside the cage body 11. When the sheep stands on the bearing plate 23, the gravity is transmitted through the weighing feet 22, so as to measure the weight of the sheep.

[0026] During the weighing process, when the sheep stands on the bearing plate 23, the weighing feet 22 and the 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 freely drop (cannot rise) inside the bottom beam 13. In this way, 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 bearing plate 23, so as to avoid affecting the weighing accuracy of the weighing scale 21.

[0027] After the measurement is completed, the motor 32 is rotated to start, driving the central shaft 31 to rotate. The central shaft 31 drives the arm beam 33 to rotate. After the arm beam 33 at the outlet of the cage body 11 rotates, the outlet of the cage body 11 is opened, and the sheep walk out from the outlet. At the same time, the arm beam 33 on the side of the cage body 11 rotates towards the inside of the cage body 11, reducing the internal space of the cage body 11 and playing a role in driving the sheep away.

[0028] While the central shaft 31 drives the arm beam 33 to rotate, an external water pump pumps disinfection liquid medicine into the inside of the arm beam 33 at the side and outlet of the cage body 11 (here, the arm beam 33 is the arm beam 33 installed at the upper end of the central shaft 31, the same below). The disinfection liquid medicine fills the strip-shaped inner cavity 35 in the arm beam 33 and is then sprayed out through the nozzles 36 at the bottom of the arm beam 33. The fan-shaped areas swept by the arm beam 33 at the side and outlet of the cage body 11 will be sprayed with disinfection liquid medicine (the fan-shaped area is a quarter of a 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 the disinfection liquid medicine), fully disinfecting the space where the sheep pass through and reducing the risk of virus transmission.

[0029] Embodiment 2 is an explanatory description made on the basis of Embodiment 1. Specifically, 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 shaft 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 far from the central shaft 31.

[0030] A liquid passing pipe 51 is installed in the arm beam 33 at the upper end of the central shaft 31. One end of the liquid passing pipe 51 is communicated with the strip-shaped inner cavity 35, and the other end of the liquid passing pipe 51 is communicated with the inside of the telescopic rod 42. A squeezing clamp 52 and a second spring 53 are installed inside the arm beam 33 at the upper end of the central shaft 31, far from the central shaft 31. The squeezing clamp 52 is elastically connected to the inside of the arm beam 33 through the second spring 53, and one side of the squeezing clamp 52 abuts against the liquid passing pipe 51. A top head 54 is fixed on the other side of the squeezing clamp 52. An arc-shaped strip 55 is installed on the side surface of the telescopic rod 42, and the top head 54 abuts against the surface of the arc-shaped strip 55.

[0031] An arc angle frame 14 is arranged on the top surface of the cage body 11, and both ends of the arc angle frame 14 penetrate through the side beams at the side and outlet of the top surface of the cage body 11 respectively. During the process of the cross door rotating towards the inside of the cage body 11, when the rotating door outside the cage body 11 rotates to close the side of the cage body 11, the convex column 43 protruding from the top surface of the arm beam 33 of the rotating door synchronously enters the sliding track 15 at the bottom of the arc angle frame 14 and slides continuously inside the sliding track 15 during the subsequent continuous rotation of the cross door.

[0032] As can be seen from Embodiment 1, when the revolving door at the outlet of the cage body 11 rotates outward to the outside of the cage body 11, the outlet of the cage body 11 opens, and the weighed sheep come out from the outlet. At the same time, the revolving door on the side of the cage body 11 rotates inward to the inside of the cage body 11. While these two revolving doors are rotating, the nozzles 36 at their bottoms spray disinfection liquid medicine. During this process, as the revolving door on the side of the cage body 11 rotates inward to the inside of the cage body 11, the convex column 43 slides in the slideway 15. Under the guiding and restricting action of the slideway 15, the convex column 43 pulls out the telescopic rod 42 from the arm beam 33, and the first spring 41 elongates. The length of the telescopic rod 42 sliding out of the arm beam 33 changes with the position of the revolving door rotating around the central axis 31 and the position of the convex column 43 in the slideway 15. Generally speaking, during the process of the revolving door rotating from the side of the cage body 11 to the inside, the closer the convex column 43 is to the diagonal of the position where the central axis 31 of the cage body 11 is located, the greater the length of the telescopic rod 42 sliding out of the arm beam 33, and the more nozzles 36 exposed at the bottom of the telescopic rod 42. When the nozzles 36 at the bottom of the telescopic rod 42 are exposed, the nozzles 36 at this place start to spray disinfection liquid medicine, so as to disinfect the space that cannot be covered by the arm beam 33 (the internal space of the cage body 11 is a cube, and the coverage range of the arm beam 33 inside the cage body 11 is a quarter cylinder. The closer to the diagonal of the position where the central axis 31 of the cage body 11 is located, the larger the space not covered by the arm beam 33, and the worse the disinfection effect. Therefore, this part of the space needs to be disinfected).

[0033] Since the activity range of the sheep during the weighing process is only at the central position inside the cage body 11, and the spaces at the four corners of the cage body 11 are rarely involved. From the perspective of cost saving, the disinfection intensity of this part of the space can be appropriately reduced. Therefore, an arc-shaped strip 55 with an inward concave arc on the side is arranged on the side of the telescopic rod 42. The heights of both ends of the arc-shaped strip 55 are the same. When the telescopic rod 42 is inside the arm beam 33, the end of the arc-shaped strip 55 away from the central axis 31 abuts against the top head 54, so that the squeezing pliers 52 compress the second spring 53 and squeeze the liquid passing pipe 51. The function of the liquid passing pipe 51 is to introduce the disinfection liquid medicine inside the arc-shaped strip 55 into the telescopic rod 42 and finally spray it out from the nozzles 36 at the bottom of the telescopic rod 42. After the liquid passing pipe 51 is squeezed by the squeezing pliers 52, the channel is closed, and the disinfection liquid medicine in the strip-shaped inner cavity 35 will not enter the telescopic rod 42.

[0034] As the arm beam 33 rotates towards the diagonal position of the central axis 31 inside the cage body 11, the arc-shaped strip 55 follows the telescopic rod 42 and gradually slides out from inside the arm beam 33. When the arm beam 33 coincides with the diagonal of the cage body 11, the top head 54 reaches the other end of the arc-shaped strip 55 from the end far away from the central axis 31 on the arc-shaped strip 55. During this process, the arc-shaped strip 55 first gradually releases the squeezing pliers 52 to squeeze the top head 54 and the squeezing pliers 52 again, so that the channel of the liquid delivery pipe 51 first gradually expands to the maximum and then gradually shrinks until it is closed again. Subsequently, the arm beam 33 continues to rotate towards the outlet of the cage body 11. Under the limiting effect of the slideway 15, the telescopic rod 42 and the arc-shaped strip 55 gradually retract into the arm beam 33 again. The change in the size of the channel of the liquid delivery pipe 51 can adjust the amount of disinfection liquid entering the inside of the telescopic rod 42 in the strip-shaped inner cavity 35, 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, it is well realized that the amount of liquid sprayed by the nozzle 36 at the bottom of the telescopic rod 42 gradually decreases at the corner of the cage body 11 and gradually increases when it reaches the middle position on the side of the cage body 11, achieving the disinfection effect while greatly reducing the waste of disinfection liquid and effectively reducing the breeding cost of sheep.

[0035] Embodiment 3. This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1 to 11 , a regulation groove 61 is provided on the side surface 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 regulation rod 64 is installed on the outside of the sliding sleeve frame 63, and the regulation rod 64 is slidably connected in the regulation groove 61.

[0036] A push rod 71 is slidably connected inside the bottom beam 13. One end of the push rod 71 is provided with a side sliding groove 72. One end of the connecting rod 62 is slidably connected inside the side sliding 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 pressing blocks 74 are installed at intervals on the top surface of the push rod 71.

[0037] Every time a sheep enters the cage body 11 and is weighed, disinfection liquid is sprayed once. After long-term spraying of the disinfection liquid, the disinfection liquid finally falls on the surface of the load-bearing plate 23, which may cause the liquid to accumulate, resulting in both a change in the weight of the load-bearing plate 23, affecting the weighing accuracy of the weighing scale 21, and causing the surface of the load-bearing plate 23 to be slippery, affecting the walking stability of the sheep. Therefore, a pushing and dialing plate 34 is provided at the bottom of the central axis 31. When the central axis 31 rotates, the pushing and dialing plate 34 idles inside the bottom beam 13. In the initial state, the regulation rod 64 is at the short end of the regulation groove 61 (the regulation groove 61 is in an L-shaped structure. Let the long side of the "L" be the long end and the short side be the short end). At this time, restricted by the regulation groove 61, the regulation rod 64 drives the connecting rod 62 to be above the pushing and dialing plate 34 through the sliding sleeve frame 63 and does not contact the pushing and dialing plate 34.

[0038] After a certain period of time, manually move the control lever 64. As shown in the attached instructions Figure 1 Move the control lever 64 to the left first and then downwards. First, the control lever 64 drives the sliding sleeve frame 63 to slide leftwards on the surface of the connecting rod 62, and then drives the connecting rod 62 to slide downwards through the sliding sleeve frame 63. When the control lever 64 reaches the end of the long side of the control groove 61, one end of the connecting rod 62 slides from the upper end to the bottom of the side sliding groove 72, and the other end of the connecting rod 62 abuts against the side surface of the push disc 34. Subsequently, during the rotation of the central shaft 31, the push disc 34 is driven to rotate. The push disc 34 pushes the connecting rod 62 to the right. The connecting rod 62 and the sliding sleeve frame 63 slide relative to each other, and the push rod 71 is pushed to slide inside the bottom beam 13 through the side sliding groove 72. The push rod 71 compresses the third spring 73 and drives the two pressing blocks 74 to slide to the right. During the sliding process of the pressing blocks 74, the corresponding triangular plates 27 are squeezed, causing the triangular plates 27 to slide downwards. The triangular plates 27 drive the corresponding pull rods 26 to slide inside the bottom beam 13. Also, because the top end of the pull rod 26 is rotatably connected to the side of the load-bearing plate 23, the pulling force of the pull rod 26 causes this side of the load-bearing plate 23 to tilt downwards, that is, the load-bearing plate 23 tilts downwards to one 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 liquid on the top surface of the load-bearing plate 23 will drain from the top surface of the load-bearing plate 23, thereby recalibrating the weight of the load-bearing plate 23.

[0039] During the tilting process of the load-bearing plate 23, the sliding rod 25 on the other side slides out of the corresponding sleeve 24 (the two will not separate), and the sleeve 24 tilts with the weighing scale 21. The functions of the sleeve 24 and the sliding rod 25 are to ensure that the load-bearing plate 23 does not slide sideways or shift during the tilting process, so as to ensure that the load-bearing plate 23 can return to its original position.

[0040] After the central shaft 31 rotates 90 degrees each time, the various structures inside the bottom beam 13 will reset, making the load-bearing plate 23 horizontally placed on the top of the weighing feet 22 again.

[0041] After the drainage is completed, push the control lever 64 upwards to make the control lever 64 return to the short end of the control groove 61. The connecting rod 62 is lifted above the push disc 34 again by the sliding sleeve frame 63 to ensure that the rotation of the push disc 34 will not cause the connecting rod 62 to slide horizontally.

[0042] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
