Description

Technical Field

[0001] The present invention relates to the field of livestock breeding, and particularly to a livestock breeding fence that can prevent livestock from climbing over. Background Art

[0002] Livestock breeding refers to the production process in which humans domesticate animals and through artificial feeding and breeding, convert forage and feed into livestock products that can be used by humans, which is an important link in the material exchange between humans and nature.

[0003] When herders conduct outdoor livestock breeding on the grassland, they need to temporarily build a breeding fence to classify, medically examine, vaccinate, and trim livestock separately. When livestock pass through the breeding fence, if they are frightened, they will have a stress reaction and may climb over the breeding fence, which affects the protection of livestock. Moreover, during the climbing process, the livestock will collide with the guardrail, causing the breeding fence to tilt, affecting the installation, disassembly, and use of the breeding fence. When installing the breeding fence, uneven ground and height on the breeding ground will cause the breeding fence to be skewed, affecting the working effect of the breeding fence.

[0004] In view of the above problems, we have developed a livestock breeding fence that can prevent livestock from climbing over. Summary of the Invention

The spring between the sliding rod and the first connecting frame is used for buffering to reduce the damage to the breeding fence. Through the meshing of the rack and the one-way gear, when livestock squeeze or impact the breeding fence, the spline drill rod moves downward again to enhance the fixing effect of the breeding fence, preventing the breeding fence from tilting due to the squeeze or impact of livestock and affecting normal use.

[0019] 3. By setting up an adjusting component, the position of the support legs is adjusted to keep the first connecting frame parallel to the ground, adapting to different heights of the ground and preventing the breeding fence from skewing due to uneven breeding ground.

On the upper sides of the first support frame 3 and the second support frame 5, an expansion assembly 8 is arranged. The expansion assembly 8 is used to increase the block, limit the direction of livestock climbing over, and at the same time increase the distance required for climbing over to prevent livestock from climbing over. The expansion assembly 8 includes a first rotating rod 801. The first rotating rod 801 is slidably connected to the second support frame 5. At the lower end of the first rotating rod 801, a limiting plate is fixedly connected. At the upper end of the first rotating rod 801, a rotating handle is fixedly connected. The limiting plate of the first rotating rod 801 cooperates with the circular limiting groove and the rectangular sliding groove at the upper part of the second support frame 5. The first rotating rod 801 is rotatably connected to a first fixing plate 802. The first fixing plate 802 is symmetrically rotatably connected to adjusting plates 803 at the front and back.

The limiting rods 805 are slidably connected to the first support frame 3. On the opposite sides of the adjusting plates 803, expansion plates 806 are rotatably connected. The expansion plates 806 are rotatably connected to the first support frame 3 and the second support frame 5. The first support frame 3 is provided with an adjusting assembly 9. The adjusting assembly 9 is used to adjust the distance between the support legs 1 and the first sliding frame 2. The second support frame 5 is provided with a fixing assembly 10. The fixing assembly 10 is used to fix the support legs 1 on the ground. The first connecting frame 4 is provided with a resisting assembly 11. The resisting assembly 11 is used to buffer the impact of livestock.

[0033] As Figure 2 and Figure 3 shown, the adjusting assembly 9 includes second sliding frames 901 arranged at equal intervals. The second sliding frames 901 are respectively slidably connected to the first support frame 3 and the second support frame 5. The second sliding frames 901 are slidably connected to the support legs 1. Between adjacent second sliding frames 901, a second connecting frame 902 is fixedly connected. On the upper side of the middle second sliding frame 901, a connecting plate 903 is fixedly connected. The connecting plate 903 is rotatably connected to a second rotating rod 904. At the front end of the second rotating rod 904, a rotating handle is fixedly connected. At the rear end of the rotating rod 904, a limiting plate is fixedly connected. In the middle of the second support frame 5, a connected circular limiting groove and a rectangular groove are arranged. The second rotating rod 904 is slidably connected to the second support frame 5. The limiting plate at the position of the second rotating rod 904 cooperates with the circular limiting groove and the rectangular groove in the middle of the second support frame 5.

[0034] As Figure 2 、 Figure 3 、Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , the fixing component 10 includes a fixing frame 1001 which is fixedly connected to the second support frame 5. The fixing frame 1001 is rotatably connected to a third rotating rod 1002. One end of the third rotating rod 1002 is provided with a rotating handle. The first support frame 3 and the second support frame 5 are rotatably connected with a spline sleeve rod 1003. The spline sleeve rod 1003 at the second support frame 5 and the third rotating rod 1002 are driven by a pulley belt. The lower first connecting frame 4 is rotatably connected with a first transmission rod 1004. The spline sleeve rod 1003 and the first transmission rod 1004 are driven by a bevel gear set. The upper side of the spline sleeve rod 1003 at the second support frame 5 is fixedly connected with a second transmission rod 1005. The second transmission rod 1005 is rotatably connected with the second support frame 5. The spline sleeve rod 1003 is in spline connection with a spline drill rod 1006. A thread groove is arranged on the outer side of the lower side of the spline drill rod 1006. The support leg 1 is fixedly connected with a limiting convex block 1008. The limiting convex block 1008 is in sliding fit with the thread groove of the spline drill rod 1006. A spring is arranged between the spline sleeve rod 1003 and the spline drill rod 1006. The spline drill rod 1006 is in sliding connection with the support leg 1. The upper end of the second transmission rod 1005 is fixedly connected with a one-way gear 1007.

[0035] As Figure 6 、 Figure 7 and Figure 8 shown in Figure 6 , Figure 7 and Figure 8 , the resisting component 11 includes a sliding rod 1101. The sliding rod 1101 is symmetrically and equidistantly slidably connected to the first connecting frame 4 in the left and right directions. A buffer pad is arranged on the rear side of the sliding rod 1101. A spring is arranged between the sliding rod 1101 and the first connecting frame 4. A connecting rod 1102 is fixedly connected between the sliding rods 1101. The middle connecting rod 1102 is fixedly connected with a second fixing plate 1103. A rack 1104 is fixedly connected to the upper side of the second fixing plate 1103. The rack 1104 is meshed with the one-way gear 1007. Contact plates 1105 are symmetrically fixedly connected to the lower side of the second fixing plate 1103 in the left and right directions.

[0036] When the user installs the breeding fence, by rotating the second rotating rod 904, the limiting plate at the second rotating rod 904 is rotated to the same direction as the middle rectangular chute of the second support frame 5. Pull the second rotating rod 904 forward so that the limiting plate at the second rotating rod 904 is slidably engaged with the middle rectangular groove of the second support frame 5, thereby driving the second sliding frame 901 to move forward, causing the second sliding frame 901 to lose its cooperation with the support leg 1. Due to gravity, the three support legs 1 protrude downward and contact the ground respectively while keeping the first connecting frame 4 parallel to the ground, keeping the breeding fence stable and preventing it from tilting, eliminating the work of leveling the ground and reducing the workload. After the contact is completed, by pushing the second rotating rod 904, the second sliding frame 901 moves backward, causing the second sliding frame 901 to cooperate with the support leg 1 again, fixing the height of the support leg 1 to facilitate adapting to the ground height. Rotate the second rotating rod 904 so that the limiting plate at the second rotating rod 904 is perpendicular to the direction of the middle rectangular chute of the second support frame 5, fixing the position of the adjusting assembly 9. The user rotates the third rotating rod 1002, and the power is transmitted to the spline sleeve rod 1003 through the bevel gear and the first transmission rod 1004. The spline drill rod 1006 is pushed downward by the spring provided between the spline sleeve rod 1003 and the spline drill rod 1006. At the same time, the thread groove of the spline drill rod 1006 cooperates with the limiting convex block 1008, causing the spline drill rod 1006 to rotate and move downward while extending into the ground to fix the breeding fence. At this time, the expansion plate 806 is in a vertical state and the adjusting plate 803 is in an inclined state. After the fixation is completed, the user rotates the first rotating rod 801, causing the limiting plate at the first rotating rod 801 to rotate to the same direction as the upper rectangular chute of the second support frame 5, making the limiting plate at the first rotating rod 801 cooperate with the upper rectangular chute of the second support frame 5. After pushing the first rotating rod 801 downward and then rotating the first rotating rod 801, the limiting plate at the first rotating rod 801 is perpendicular to the direction of the upper rectangular chute of the second support frame 5, fixing the height of the first fixing plate 802. Through the sliding cooperation of the limiting rod 805 and the first support frame 3 in the vertical direction, the direction is restricted synchronously, causing the adjusting plate 803 to change from an inclined state to a horizontal state, rotating the first rotating rod 801 to fix the height, and at the same time changing the expansion plate 806 from a vertical state to an inclined state, blocking the direction when livestock climb over, increasing the width of the top of the breeding fence, increasing the distance required for livestock to climb over, and increasing the difficulty for sheep to climb over the breeding fence. After the adjustment is completed, the breeding fences are fixed through the sliding cooperation of the sliding sleeve 6 and the sliding pin 7, forming a guiding channel for the breeding fences.

[0037] When livestock pass through the breeding fence, when the livestock are frightened, they will hit the breeding fence. The livestock cause the sliding rod 1101 to slide by squeezing or hitting. The sliding rod 1101 slides forward along the first connecting frame 4. Through the buffer pad arranged at the sliding rod 1101 and the spring arranged between the sliding rod 1101 and the first connecting frame 4, the impact on the livestock and the guardrail is reduced. The sliding rod 1101 drives the second fixed plate 1103 to move forward through the connecting rod 1102, so that the rack 1104 moves forward synchronously. The rack 1104 meshes with the one-way gear 1007 to make the one-way gear 1007 rotate. Then, the power is transmitted to the spline sleeve rod 1003 through the second transmission rod 1005, so that the spline drill rod 1006 moves downward again. By the downward movement of the spline drill rod 1006, the fixing effect of the breeding fence is improved. When the sliding rod 1101 is no longer squeezed, the spring between the first connecting frame 4 and the sliding rod 1101 resets the sliding rod 1101.

[0038] When disassembling the breeding fence, by rotating the third rotating rod 1002 in the reverse direction, the spline drill rod 1006 is rotated and lifted through the spline sleeve rod 1003 and the limit convex block 1008. By releasing the cooperation of the sliding sleeve 6 and the sliding pin 7 of the adjacent breeding fence, the adjacent breeding fences are separated. By rotating the second rotating rod 904, the limiting plate at the second rotating rod 904 is rotated to the same direction as the middle rectangular chute of the second support frame 5, and then the second rotating rod 904 is pulled, so that the second sliding frame 901 loses the limit on the support leg 1, and the support leg 1 is retracted. Then, after pushing the second rotating rod 904 and then rotating the second rotating rod 904, the limiting plate at the second rotating rod 904 is rotated to a direction perpendicular to the middle rectangular chute of the second support frame 5, and the support leg 1 is limited again through the second sliding frame 901. By rotating, pulling, and then rotating the first rotating rod 801, the first rotating rod 801 is released from the limit and lifted to a position and then limited again, so that the adjusting plate 803 is changed from a horizontal state to an inclined state, and at the same time, the expansion plate 806 is changed from an inclined state to a vertical state, and the breeding fence is carried.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, as Figure 1 、 Figure 8 and Figure 9 shown, it further includes a sliding bracket 12. Chutes are symmetrically arranged on the left and right sides of the middle support leg 1. The sliding bracket 12 is slidably connected to the chute of the support leg 1. The chute of the support leg 1 is an inclined chute that is high at the back and low at the front. A spring is arranged between the sliding bracket 12 and the chute of the support leg 1. The sliding bracket 12 is in contact with the contact plate 1105.

[0041] When livestock pass through the breeding fence, when the livestock squeeze or impact the sliding rod 1101, the contact plate 1105 is moved forward through the second fixed plate 1103, so that the sliding bracket 12 moves along the inclined grooves on both sides of the middle support leg 1, and the bottom of the sliding bracket 12 contacts the ground, forming a triangular support structure, forming a more stable state, preventing the breeding fence from tilting due to the squeezing or impact of livestock. When the sliding rod 1101 is no longer squeezed, the sliding bracket 12 is reset through the spring between the sliding bracket 12 and the middle support leg 1, reducing the space occupation and facilitating recycling and transportation.

[0042] As Figure 1 and Figure 9 shown, it also includes a first foot 13 and a second foot 14. The first foot 13 is rotatably connected to the lower side of the support leg 1, and the second foot 14 is rotatably connected to the lower side of the sliding bracket 12. When the support leg 1 and the sliding bracket 12 contact the ground, the first foot 13 and the second foot 14 that are rotatably connected respectively contact the ground, increasing the contact area with the ground to adapt to the undulation of the ground and preventing the overall shaking of the breeding fence.

[0043] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by using equivalent replacements or equivalent transformations fall within the protection scope of the present invention.
