Description

Technical Field

[0001] This utility model relates to the technical field of animal husbandry, specifically to an adjustable livestock fence. Background Technology

[0002] Conventional livestock fences typically have a single gate, which can easily cause congestion when livestock enter and exit in large numbers. This not only affects passage but may also cause the fence to deform and collapse due to collisions.

[0003] Access gates are generally of a fixed size, and for ease of management, only one access gate is usually set up or opened at a time. The size of the access gate is difficult to change later. Livestock at different growth stages have different sizes, and as the livestock gradually mature, the size of the access gate becomes difficult to meet their needs for entry and exit, resulting in overcrowding.

[0004] Therefore, the access gates of existing livestock pens are difficult to accommodate livestock at different growth stages. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable livestock fence to solve the problem that the access gates of existing livestock fences are difficult to adapt to the entry and exit of livestock at different growth stages.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: An adjustable livestock fence includes a gate frame and a plurality of fence frames, wherein the gate frame and all the fence frames are connected end to end to form a closed fence; The gate frame includes a frame and a plurality of vertical bars arranged horizontally within the frame. The length of the vertical bars is arranged in the vertical direction, and a door passage is formed between two adjacent vertical bars. A movable gantry is also provided within the frame. The movable gantry is arranged side by side with the vertical rod and located outside the vertical rod. The movable gantry includes at least two horizontally arranged sliding rods and multiple vertically arranged gantry rods connected between the two sliding rods. The sliding rods are horizontally slidably arranged in grooves opened in the inner wall of the frame.

[0007] Furthermore, the number of gate posts is less than the number of vertical posts, and the spacing between some adjacent gate posts is equal to the spacing between some adjacent vertical posts.

[0008] Furthermore, adjacent fence frames are hinged together; The two ends of the gate frame are hinged or detachably connected to the corresponding fence frame.

[0009] Furthermore, two transverse through holes are provided on the vertical side plate of the frame, directly opposite the end of the sliding rod; An operating lever is connected to the ends of the two sliding rods; The operating lever extends through the transverse through-hole to the outside.

[0010] Furthermore, the two operating levers are connected by a pull rod.

[0011] Furthermore, the pull rod is an outwardly protruding arc-shaped rod.

[0012] Compared to existing technologies, the advantages of this application are: The fence provided by this utility model mainly sets one of the fence frames as a gate frame, and forms a gate passage (for livestock to enter and exit) on the gate frame. At the same time, by moving the gate frame, the gate passage is opened when it overlaps, and the gate passage is reduced or the entry and exit is restricted when it is misaligned. The size of the gate passage can be flexibly adjusted to accommodate livestock at different growth stages. Multiple gate passages can be set at the same time, and the entry and exit can be opened, adjusted and restricted simultaneously. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figure 1 As shown, this utility model provides an adjustable livestock fence, which mainly includes: The gate frame 1, multiple fence frames 2, and a movable gate frame 3 installed inside the gate frame 1 are designed to accommodate the penning and entry / exit needs of livestock of different sizes, and are especially suitable for scenarios where young and adult livestock are raised together or raised in different time periods in farms.

[0018] Among them, the gate frame 1, as the core gate structure of the fence, has a frame 101. Inside the frame 101, multiple vertical bars 102 are evenly arranged in the horizontal direction. A gate passage 103 for livestock to pass through is naturally formed between two adjacent bars 102. Multiple fence frames 2 are connected end to end with the gate frame 1 to enclose a closed breeding space. The number of fence frames 2 can be flexibly increased or decreased according to the size of the breeding site to adapt to the needs of different areas.

[0019] To enable flexible adjustment of the width of the doorway 103, and to meet the needs of preventing young animals (such as piglets and lambs) from squeezing out and allowing adult livestock (such as sows and adult sheep) to pass smoothly.

[0020] In this embodiment, a movable gantry 3 is assembled inside the frame 101. The movable gantry 3 is arranged side by side with the vertical rod 102 and located outside the vertical rod 102. It consists of two horizontally arranged sliding rods 301 and multiple vertical gantry rods 302 fixedly connected between the two sliding rods 301.

[0021] Correspondingly, the inner wall of the frame 101 is provided with a groove 4 that is adapted to the sliding rod 301. The sliding rod 301 can slide horizontally along the groove 4, thereby driving the door rod 302 to move synchronously, so that it is misaligned with the vertical rod 102, thereby changing the width of the door passage 103 and solving the problem that traditional fixed doors cannot adapt to livestock of different growth stages.

[0022] In actual farming, to avoid the problem that "the area on both sides is not covered when the gate is moved, causing livestock to run out from the edge", if the gate cannot cover the gap on both sides during the adjustment process, or there are still uncovered areas on both sides after adjustment, the risk of livestock escaping will increase.

[0023] This embodiment further provides a preferred design: the number of door bars 302 is set to be less than the number of vertical bars 102, and the spacing between some adjacent door bars 302 is equal to the spacing between some adjacent vertical bars 102.

[0024] Specifically, as follows: Taking the total number of vertical poles 102 as 6 and the spacing between them as 20cm, the 6 vertical poles form 5 passages 20cm wide. Among them, only the middle 3 passages are the planned "accessible passages", and the passages on both sides are "fixed blocking areas". The number of gate poles 302 is set to 4, which is 2 fewer than the vertical poles. The spacing between the 4 gate poles is also 20cm. The 4 gate poles can completely cover the area of ​​the middle 3 accessible passages.

[0025] At this time, the 20cm wide passages on both sides of the gate frame 1 are always in a "fixed blocking" state - no matter whether the gate bar 302 slides to the left or right, it only moves within the range of the three middle passages. The passages on both sides are always blocked by the vertical bar 102 and the edge structure of the gate bar 302, avoiding "gap that cannot be covered" during the adjustment process, and fundamentally preventing livestock from running out from the unblocked areas on both sides.

[0026] When it is necessary to restrict the entry and exit of young livestock, the gate 302 and the middle vertical bar 102 are staggered to form a seamless obstruction between the three middle access channels, and only some channels are opened when specific needs are required; when normal passage is required, the gate 302 and the middle vertical bar 102 are aligned, and the three middle access channels are kept at a uniform distance to allow livestock to enter and exit in an orderly manner.

[0027] This design ensures flexible adjustment of the central access passage while preventing livestock from escaping due to insufficient coverage by fixed shielding areas on both sides, making the gate design more in line with the core needs of "controllable passage and escape prevention" in actual breeding.

[0028] Furthermore, considering the convenience of fence assembly and storage, this embodiment optimizes the connection structure between fence frame 2 and gate frame 1: Adjacent fence frames 2 are connected by a hinge, such as by fixing with hinges. The hinge structure allows the fence frames 2 to be folded and stored, which can greatly reduce storage space when not in use, and has good impact resistance, which can withstand the collisions of livestock during daily activities.

[0029] The gate frame 1 and the corresponding fence frame 2 offer two connection options: a hinged connection suitable for long-term fixed use scenarios, ensuring a firm connection; and a pin-type detachable connection suitable for scenarios that require frequent adjustment of the fence area, such as seasonal expansion / reduction of the enclosure area. Disassembly can be achieved by simply pulling out the pin, balancing stability and flexibility.

[0030] To ensure the stability of the movable gantry 3 after adjustment, and to prevent the passage width from shifting due to livestock collisions or slight vibrations of the fence.

[0031] Implementation method: A limiting design is added to the control structure of the movable gantry 3: A transverse through hole 105 is provided on the vertical side plate 104 of the frame 101 for the operating rod 5 to pass through. The ends of the two sliding rods 301 are respectively fixedly connected to the operating rod 5. The end of the operating rod 5 away from the sliding rod 301 extends to the outside of the frame 101 through the transverse through hole 105, which is convenient for the user to operate from the outside of the fence. On one of the operating rods 5, multiple limiting through holes are opened at intervals along the length direction. Correspondingly, a positioning through hole that matches the diameter of the limiting through hole is opened on the vertical side plate 104 next to the transverse through hole 105.

[0032] It should also be noted that this preferred design is fully compatible with the aforementioned limiting structure. When the door rod 302 slides to the target mating position, it can still be locked by inserting the limiting rod into the through hole. Furthermore, the matching design of the spacing between the door rod 302 and the vertical rod 102 makes the limiting position easier to control, eliminating the need for repeated adjustments by the user and significantly improving operational efficiency.

[0033] In actual use, when the operating lever 5 is pushed to move the gantry 3 to the target position, the limit rod can be inserted into the positioning through hole and the corresponding limit through hole to lock the position of the operating lever 5, ensuring that the gantry 3 remains stable and further improving the reliability of use.

[0034] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
