Description

Technical Field

[0001] This utility model relates to the technical field of milking equipment, and in particular to a rotary milking stand. Background Technology

[0002] The rotary milking stand uses a rotating circular milking table for continuous milking operations. Milkers clean and disinfect the animal's udder and fit the milking cups at the entrance. Since there is no need to walk back and forth, it is easy to operate, has high labor efficiency, and requires only a small number of people to carry out large-scale continuous milking operations.

[0003] To allow animals to leave the milking parlor voluntarily after milking, rotary milking parlors are equipped with devices to repel them. For example, Chinese utility model patent CN213404515U, entitled "A Device for Driving Cattle Outlets from a Rotary Milking Parlor," includes a drive motor suspended above the cow outlet of the rotary milking parlor. At least one flexible hose is connected to the output shaft of the drive motor, and the axial direction of each hose is perpendicular to the axis of the output shaft. The drive motor drives the hose to rotate, thereby striking the head of the cow to drive it away from the rotary milking parlor. This method, which uses striking to drive the cow, easily causes significant stress in the cow, leading to agitation and potential damage to the equipment or the cow itself. Utility Model Content

[0004] The purpose of this invention is to provide a rotary milking stand that is gentler in repelling animals, less likely to cause stress to the animals, and has a better repelling effect.

[0005] The technical solution adopted by this utility model is: a rotary milking stand, including a rotating platform, a drive mechanism and a slide rail;

[0006] The rotating platform has a ring structure and can rotate around its axis. The rotating platform is divided into several milking stations around its axis. The opposite sides of the milking stations arranged in sequence along the radial direction of the rotating platform are called the head-facing side and the in-and-out side, respectively. The opposite sides of the milking stations arranged in sequence along the rotation direction of the rotating platform are called the first dividing side and the second dividing side, respectively.

[0007] The slide rail is located above the rotating platform and includes a first slide rail, a second slide rail, and a third slide rail. The first slide rail is an arc-shaped structure arranged around the axis of the rotating platform, and its travel path is parallel to the horizontal plane. The second and third slide rails are curved structures arranged around the axis of the rotating platform. The second and third slide rails are located between the two ends of the first slide rail. One end of the second slide rail is connected to one end of the first slide rail, and one end of the third slide rail is connected to the other end of the first slide rail. The height of the second and third slide rails gradually increases in the direction away from the first slide rail, so that a retraction and maintenance space is formed between the other ends of the second and third slide rails.

[0008] One driving component corresponds to one milking station. The driving component includes a driving part, a rotating shaft part, and a sliding part, which are arranged sequentially along the radial direction of the rotating platform. The rotating shaft part is rotatably mounted on the rotating platform, and its rotation axis is set horizontally and perpendicular to the radial direction of the rotating platform. One end of the driving part is connected to the rotating shaft part, and the driving part is located on the head side of the milking station, with the center of gravity of the driving component on the driving part. One end of the sliding part is connected to the rotating shaft part, and the sliding part is slidably mounted on the lower side of the slide rail. The sliding part can be driven by the rotating platform to move along the slide rail. When the sliding part is located in the first slide of the slide rail, the vertical plane containing the rotation axis of the driving part and the rotating shaft part forms an angle and moves away from the milking station.

[0009] The working principle of this utility model is as follows:

[0010] In use, the second and third slides are located near the exit of the milking table. The rotating platform drives each milking station to make circular motion by rotating, so that the sliding part of the repulsion part on each milking station passes through the first slide, the second slide, the repulsion holding space, and the second slide in a cycle.

[0011] When the sliding part of the repelling component is located in the first slide of the slide rail, the repelling part forms an angle with the vertical plane where the rotation axis of the rotating shaft is located and is far away from the milking station, so that the head of the animal can be extended out of the milking station and face the side after entering the milking station.

[0012] When the sliding part of the repelling component slides from the first slide into the second slide, the height of the second slide gradually increases in the direction opposite to the first slide. Since the repelling part of the repelling component forms an angle with the vertical plane containing the rotation axis of the rotating shaft, the center of gravity of the repelling component is on the repelling part. This causes the repelling component to rotate under its own weight at the end of the repelling part away from the rotating shaft. The repelling part gradually moves towards the head-facing side of the milking station, and the sliding part gradually moves upwards, gradually reducing the external space on the head-facing side of the milking station. This allows the repelling part of the repelling component to repel the animal's head, thereby driving the animal to leave the milking station and exit from the milking stand. This continues until the sliding part of the repelling component enters the repelling holding space, where the repelling part is parallel to the vertical plane containing the rotation axis of the rotating shaft.

[0013] When the sliding part of the repelling component slides from the repelling support space into the third slide, the height of the third slide gradually increases in the direction away from the first slide (i.e., the height of the third slide gradually decreases in the direction towards the first slide). The sliding part of the repelling component is squeezed downward by the third slide, causing the repelling component to rotate. This causes the repelling part to gradually move away from the milking station head, gradually expanding the external space on the side of the milking station head until the sliding part of the repelling component slides into the first slide. The repelling part maintains a certain angle with the vertical plane containing the rotation axis of the rotating shaft, thus preparing for the next batch of animals to enter the milking station.

[0014] This solution uses a repelling mechanism that rotates to gradually reduce the external space facing the milking station head, thus repelling the animals. This method is gentler and more effective. Because the second and third slides are designed with gradually increasing heights in the direction opposite to the first slide, and the rotating platform rotates slowly, the repelling mechanism rotates slowly, minimizing stress on the animals during repelling. Furthermore, since the repelling mechanism is driven by its own weight, if the animal's head exits slowly, the repelling mechanism will support the animal's head without forcibly squeezing it, thus preventing injury and ensuring good safety.

[0015] Furthermore, in the rotary milking stand described above, a counterweight is provided on the end of the driving part of the driving member that is away from the rotating shaft.

[0016] Furthermore, in the rotary milking stand described above, a first guide roller is rotatably provided on the sliding part of the retractor, the rotation axis of the first guide roller is arranged along the axis of the sliding part, and the first guide roller slidably abuts against the lower side of the slide rail.

[0017] Furthermore, in the rotary milking stand described above, the sliding part of the driving member is sequentially formed with a first connecting part, a first guiding part, and a first stud part along its axial direction. One end of the first connecting part is connected to the rotating shaft part, and the first guide roller is rotatably mounted on the first guiding part. It also includes a first clamping nut, which is threadedly connected to the first stud part. The first clamping nut cooperates with the first connecting part to clamp and position the first guide roller in the axial direction.

[0018] Furthermore, as described above, a rotary milking stand also includes a first anti-loosening nut, which is threaded onto the first stud and rests on the side of the first clamping nut facing away from the first guide roller.

[0019] Furthermore, as described above, a rotary milking stand also includes a driving gate and a driving component. One driving gate corresponds to one milking station. One end of the driving gate is a rotating end, and the other end is a free end. The rotating end of the driving gate is rotatably mounted on the rotating platform. The rotation axis of the driving gate is vertically positioned and located near the angle between the entrance / exit side and the second dividing side of the milking station. In the initial state, the free end of the driving gate is located near the angle between the head-facing side and the second dividing side of the milking station. The driving gate rotates, causing its free end to move in the direction of the angle between the entrance / exit side and the first dividing side, and the driving gate has a tendency to return to its initial state. The driving component is fixed relative to the ground and located above the rotating platform. The rotating platform rotates, causing the driving gate of the milking station adjacent to the driving component in the rotation direction to be squeezed and rotated by the driving component.

[0020] Furthermore, as described above, a rotary milking stand also includes a guardrail and a divider. The guardrail and divider are fixedly installed on the ground and located around the periphery of the rotating platform. The guardrail is an arc-shaped structure arranged around the axis of the rotating platform. The divider is located between the two ends of the guardrail, such that an entrance is formed between the divider and one end of the guardrail, and an exit is formed between the divider and the other end of the guardrail. The second and third slide rails of the slide rail are located near the exit. An extension is formed on the divider, which is higher than the drive gate and located between the milking station near the entrance and the milking station near the exit. The drive unit is located on the lower side of the extension of the divider.

[0021] Furthermore, in the aforementioned rotary milking stand, the axis of the driving member is arranged vertically, and the driving member sequentially forms a second connecting part, a second guiding part, and a second stud part along its axial direction. The upper end of the second connecting part is connected to the extension part, and a flange is formed on the circumferential surface of the lower end of the second connecting part. It also includes a second guide roller and a second clamping nut. The second guide roller is rotatably mounted on the second guiding part of the driving member. The second clamping nut is threadedly connected to the second stud part of the driving member, and the second clamping nut cooperates with the second connecting part to clamp and position the second guide roller in the axial direction.

[0022] Furthermore, as described above, a rotary milking stand also includes a second anti-loosening nut, which is threaded onto the second stud portion of the drive component and is positioned on the side of the second clamping nut that faces away from the second guide roller.

[0023] Furthermore, in the rotary milking stand described above, the slide rail also includes a fourth slide rail, which is an arc-shaped structure surrounding the rotating platform. The travel trajectory of the fourth slide rail is parallel to the horizontal plane. The ends of the second and third slide rails that are away from the first slide rail are connected by the fourth slide rail, so that the first, second, third, and fourth slide rails are connected to form a closed ring structure.

[0024] The beneficial effects of this invention are: the method of repelling animals is gentler, less likely to cause stress to animals, and the repelling effect is better. Attached Figure Description

Detailed Implementation

[0037] like Figures 1 to 10 An embodiment of a rotary milking stand includes a rotating platform 1, a drive component 5, and a slide rail 4;

[0038] The rotating platform 1 has a ring structure and can rotate around its axis. Several partitions 2 are evenly arranged around the axis of the rotating platform 1, so that the rotating platform 1 is divided into several milking stations 11 around its axis. The opposite sides of the milking stations 11 arranged in the radial direction of the rotating platform 1 are called the head-facing side and the in-and-out side, respectively. The head-facing side is located closer to the center of the rotating platform 1. The opposite sides of the milking stations 11 arranged in the rotation direction of the rotating platform 1 are called the first partition side and the second partition side, respectively. A feed trough 3 is also provided on the rotating platform 1. The feed trough 3 is a ring structure arranged around the axis of the rotating platform 1. The feed trough 3 is located outside the head-facing side of the milking station 11. The feed trough 3 is divided into several feed chambers 31 along its travel path. One feed chamber 31 is corresponding to one head-facing side of the milking station 11.

[0039] The slide rail 4 is located above the rotating platform 1. The slide rail 4 includes a first slide rail 41, a second slide rail 42, and a third slide rail 43. The first slide rail 41 is an arc-shaped structure arranged around the axis of the rotating platform 1, and the travel trajectory of the first slide rail 41 is parallel to the horizontal plane. The second slide rail 42 and the third slide rail 43 are curved structures arranged around the axis of the rotating platform 1. The second slide rail 42 and the third slide rail 43 are located between the two ends of the first slide rail 41. One end of the second slide rail 42 is connected to one end of the first slide rail 41, and one end of the third slide rail 43 is connected to the other end of the first slide rail 41. The second slide rail 42 and the third slide rail 43 are arranged sequentially along the rotation direction of the rotating platform 1. The height of the second slide rail 42 and the third slide rail 43 gradually increases in the direction away from the first slide rail 41, so that a retraction and maintenance space is formed between the other end of the second slide rail 42 and the other end of the third slide rail 43.

[0040] One repelling component 5 corresponds to one milking station 11. The repelling component 5 includes a repelling part 51, a rotating shaft part 52, and a sliding part 53. The repelling part 51, the rotating shaft part 52, and the sliding part 53 are arranged sequentially along the radial direction of the rotating platform 1. The rotating shaft part 52 is rotatably mounted on the rotating platform 1, and the axis of rotation of the rotating shaft part 52 is arranged horizontally and perpendicular to the radial direction of the rotating platform 1. The repelling part 51 includes three repelling rods, which are arranged sequentially and separately along the axis of the rotating shaft part 52. One end of each of the three repelling rods is connected to the rotating shaft part 52. The repulsing part 51 is located on the outer side of the head facing the milking station 11, and the center of gravity of the repulsing part 5 is located on the repulsing part 51; one end of the sliding part 53 is connected to the rotating shaft part 52, and the angle between the axis of the sliding part 53 and the axis of the repulsing part 51 is 135°. The sliding part 53 is slidably disposed on the lower side of the slide rail 4. The sliding part 53 can be driven by the rotating platform 1 to move along the slide rail 4. When the sliding part 53 is located in the first slide 41 of the slide rail 4, the vertical plane where the axis of rotation of the repulsing part 51 and the rotating shaft part 52 are located forms an angle of 45° and moves away from the milking station 11.

[0041] The working principle of this embodiment is as follows:

[0042] In use, the second slide 42 and the third slide 43 are located near the outlet 30 of the milking table. The rotating platform 1 drives each milking station 11 to make circular motion by rotating, so that the sliding part 53 of the repulsion member 5 on each milking station 11 passes through the first slide 41, the second slide 42, the repulsion holding space, and the second slide 42 in a cycle.

[0043] When the sliding part 53 of the repelling part 5 is located in the first slide 41 of the slide rail 4, the repelling part 51 forms an angle with the vertical plane where the rotation axis of the rotating shaft part 52 is located and moves away from the milking station 11, so that the head of the animal can extend out of the milking station 11 and face the side after entering the milking station 11.

[0044] When the sliding part 53 of the repelling member 5 slides from the first slide rail 41 into the second slide rail 42, the height of the second slide rail 42 gradually increases in the direction away from the first slide rail 41. Furthermore, since the repelling part 51 of the repelling member 5 forms an angle with the vertical plane containing the rotation axis of the rotating shaft part 52, the center of gravity of the repelling member 5 is located on the repelling part 51. This causes the repelling member 5 to rotate under its own weight at the end of the repelling part 51 away from the rotating shaft part 52, resulting in the repelling part 5... 1. The head of the animal gradually moves towards the milking station 11 and the sliding part 53 gradually moves upward, so that the external space of the milking station 11 with the head facing to the side is gradually reduced, thereby realizing that the driving part 51 of the driving member 5 drives the head of the animal, thereby driving the animal to leave the milking station 11 on its own and leave from the exit 30 of the milking table; until the sliding part 53 of the driving member 5 enters the driving and maintaining space, and the driving part 51 is parallel to the vertical plane where the rotation axis of the rotating shaft part 52 is located.

[0045] When the sliding part 53 of the repelling member 5 slides from the repelling support space into the third slide rail 43, the height of the third slide rail 43 gradually increases in the direction away from the first slide rail 41 (i.e., the height of the third slide rail 43 gradually decreases in the direction towards the first slide rail 41). The sliding part 53 of the repelling member 5 is squeezed by the third slide rail 43 and moves downward, causing the repelling member 5 to rotate. This causes the repelling part 51 to gradually move away from the head-facing side of the milking station 11, gradually expanding the external space of the head-facing side of the milking station 11 until the sliding part 53 of the repelling member 5 slides into the first slide rail 41. The repelling part 51 maintains a certain angle with the vertical plane where the rotation axis of the rotating shaft part 52 is located, thus preparing for the next batch of animals to enter the milking station 11.

[0046] This solution uses the repulsion component 5 to gradually reduce the external space facing the head of the milking station 11 by rotating, thereby repelling the animals. This method of repelling animals is gentler and more effective. Due to the design of the second slide 42 and the third slide 43, which are each designed to gradually increase in height in the direction away from the first slide 41, and the slow rotation speed of the rotating platform 1, the repulsion component 5 rotates relatively slowly, making it less likely for the animals to experience stress during the repulsion process. In addition, when the repulsion component 5 is performing its repulsion work, since the repulsion component 5 is driven to rotate by its own weight, if the animal's head exits slowly, the repulsion component 51 will support the animal's head without forcibly squeezing it, thus avoiding injury to the animal from the repulsion component 5 and providing better safety.

[0047] like Figure 1 and Figure 2As shown, the slide rail 4 also includes a fourth slide rail 44, which is an arc-shaped structure surrounding the rotating platform 1. The travel trajectory of the fourth slide rail 44 is parallel to the horizontal plane. The ends of the second slide rail 42 and the third slide rail 43 that are away from the first slide rail 41 are connected by the fourth slide rail 44, so that the first slide rail 41, the second slide rail 42, the third slide rail 43 and the fourth slide rail 44 are connected to form a closed ring structure. By setting the fourth slide rail 44, it can be ensured that the sliding part 53 of the drive member 7 remains against the lower side of the slide rail 4, making the movement of the drive member 7 more stable. Furthermore, through this design, the slide rail 4 becomes a closed ring structure, improving the structural strength of the slide rail 4 and further making the movement of the drive member 7 more stable.

[0048] like Figure 8 , Figure 9 and Figure 10 As shown, a counterweight 54 is provided on the end of the repulsing part 51 away from the rotating shaft part 52 of the repulsing member 5. By providing the counterweight 54, the center of gravity of the repulsing member 5 is made closer to the end of the repulsing part 51 away from the rotating shaft part 52, which ensures that the sliding part 53 of the repulsing member 5 can slide against the lower side of the slide rail 4, and ensures that the repulsing part 51 can drive the repulsing member 5 to rotate when the sliding part 53 slides out of the first slide rail 41, thereby improving the reliability of the repulsing member 5.

[0049] like Figure 8 , Figure 9 and Figure 10 As shown, a first guide roller 55 is rotatably mounted on the sliding part 53 of the repelling member 5. The rotation axis of the first guide roller 55 is arranged along the axis of the sliding part 53, and the first guide roller 55 slidably abuts against the lower side of the slide rail 4. By providing the first guide roller 55, the friction between the sliding part 53 of the repelling member 5 and the slide rail 4 can be reduced, making the sliding part 53 slide more smoothly along the slide rail 4, and avoiding damage to the sliding part 53 and the slide rail 4 due to friction during use, thereby improving their service life.

[0050] like Figure 8 , Figure 9 and Figure 10 As shown, the sliding portion 53 of the repelling member 5 is sequentially formed with a first connecting portion 531, a first guide portion 532, and a first stud portion 533 along its axial direction. One end of the first connecting portion 531 is connected to the rotating shaft portion 52, and the first guide roller 55 is rotatably mounted on the first guide portion 532. It also includes a first clamping nut 56, which is threaded onto the first stud portion 533. The first clamping nut 56 cooperates with the first connecting portion 531 to clamp and position the first guide roller 55 axially. This structure makes the installation and disassembly of the first guide roller 55 more convenient, facilitating maintenance or replacement of the first guide roller 55.

[0051] like Figure 8 , Figure 9 and Figure 10 As shown, this embodiment also includes a first anti-loosening nut 57, which is threaded onto the first stud portion 533. The first anti-loosening nut 57 is positioned on the side of the first clamping nut 56 facing away from the first guide roller 55. By adding the first anti-loosening nut 57, the first clamping nut 56 can be prevented from loosening during use, thereby improving the stability of the first guide roller 55.

[0052] like Figure 4 and Figure 6 As shown, this embodiment also includes a driving gate 6 and a driving component 7. One driving gate 6 corresponds to one milking station 11. One end of the driving gate 6 is a rotating end, and the other end is a free end. The rotating end of the driving gate 6 is rotatably mounted on the rotating platform 1. The rotation axis of the driving gate 6 is vertically positioned and located near the angle between the entrance / exit side and the second dividing side of the milking station 11. In the initial state, the free end of the driving gate 6 is located near the angle between the head-facing side and the second dividing side of the milking station 11. The driving gate 6 rotates, causing its free end to move in the direction of the angle between the entrance / exit side and the first dividing side. An elastic element (not shown in the figure) is provided on the driving gate 6, giving the driving gate 6 a tendency to return to its initial state. The driving component 7 is fixed relative to the ground and positioned above the rotating platform 1. The rotating platform 1 rotates, causing the driving gate 6 of the milking station 11 adjacent to the driving component 7 in the rotation direction to be squeezed and rotated by the driving component 7. As the milking station 11 moves along with the rotating platform 1, the herding gate 6 is squeezed and rotated by the drive component 7. This causes the animals in the milking station 11 to be driven away by the herding gate 6 until the herding gate 6 has completely passed the position of the drive component 7. The herding gate 6 then returns to its initial state under the action of the elastic component, preparing for the next batch of animals to enter the milking station 11. By adding the herding gate 6 and the drive component 7, it is ensured that the animals are driven away from the milking station 11, further improving the herding effect. Furthermore, because the rotating platform 1 rotates slowly, the relative movement speed between the herding gate 6 and the drive component 7 is not high, so the rotation speed of the herding gate 6 is also relatively slow. The herding method is gentler and less likely to cause stress to the animals, resulting in better safety.

[0053] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment also includes a guardrail 8, a partition frame 9, and a support frame 10. The support frame 10 is fixed to the ground and is connected to the guardrail 8 and the slide rail 4 for support. The partition frame 9 is fixed to the ground and is connected to the support frame 10 to form an integral structure. The guardrail 8 and the partition frame 9 are located on the periphery of the rotating platform 1. The guardrail 8 is an arc-shaped structure arranged around the axis of the rotating platform 1. The partition frame 9 is located between the two ends of the guardrail 8, so that an entrance 20 is formed between the partition frame 9 and one end of the guardrail 8, and an exit 30 is formed between the partition frame 9 and the other end of the guardrail 8. The second slide rail 42, the third slide rail 43, and the fourth slide rail 44 of the slide rail 4 are located near the exit 30. An extension 91 is formed on the partition frame 9. The extension 91 is higher than the driving gate 6 and is located between the milking station 11 adjacent to the entrance 20 and the milking station 11 adjacent to the exit 30. The driving member 7 is located on the lower side of the extension 91 of the partition frame 9. The milking station's exit 30 and entrance 20 are formed by the combination of guardrails 8 and dividers 9, facilitating the diversion and guidance of animals. In this embodiment, the walking path of the milking station's exit 30 spans the width of two milking stations 11. The overall walking path of the combination of the second slide 42, the third slide 43, and the fourth slide 44 also spans the width of two milking stations 11, thus allowing animals sufficient time to leave the milking station 11 after being driven away by the repelling device 5. When the milking station 11 moves from the exit 30 position to the entrance 20 position, the driving device 7 drives the repelling gate 6 to rotate, and the repelling device 5 returns to the state away from the milking station 11. When the milking station 11 has completely moved to the entrance 20, the repelling gate 6 returns to its initial state. Through this design, the action of the repelling gate 6 lags behind the action of the repelling device 5, making the sequence of their actions more reasonable. This avoids the animal's head being squeezed by the repelling gate 6 before it has completely retreated back to the milking station 11, resulting in better safety and a better repelling effect. In addition, the guardrail 8, the partition frame 9, and the slide rail 4 are connected into an integrated structure by the support frame 10, making the connection structure of the guardrail 8, the partition frame 9, and the slide rail 4 more stable.

[0054] like Figure 6As shown, the drive member 7 is vertically oriented, and along its axial direction, it sequentially forms a second connecting portion 71, a second guide portion 72, and a second stud portion 73. The upper end of the second connecting portion 71 is connected to the extension portion 91, and a flange 711 is formed on the circumferential surface of the lower end of the second connecting portion 71. It also includes a second guide roller 74 and a second clamping nut 75. The second guide roller 74 is rotatably mounted on the second guide portion 72 of the drive member 7. The second clamping nut 75 is threaded onto the second stud portion 73 of the drive member 7, and the second clamping nut 75 cooperates with the second connecting portion 71 to clamp and position the second guide roller 74 axially. By adding the second guide roller 74, the friction between the drive member 7 and the driving door 6 can be reduced, making the rotation of the driving door 6 more stable and preventing damage to the driving door 6 and the drive member 7 due to friction during use, thereby improving their service life.

[0055] like Figure 6 As shown, this embodiment also includes a second anti-loosening nut 76, which is threadedly connected to the second stud portion 73 of the drive member 7. The second anti-loosening nut 76 is positioned on the side of the second clamping nut 75 that faces away from the second guide roller 74. By adding the second anti-loosening nut 76, the second clamping nut 75 can be prevented from loosening during use, thereby improving the stability of the second guide roller 74.
