Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and in particular to an adjustable livestock pen. Background Technology

[0002] Livestock pens refer to the fences or enclosures used for raising livestock in animal husbandry. These pens are usually designed and divided according to the type, size and feeding needs of the livestock, providing them with appropriate living space and feeding environment. The setting of livestock pens helps to manage and protect livestock, ensuring their health and safety.

[0003] For example, patent document CN221598891U discloses an adjustable livestock pen, belonging to the field of livestock breeding technology. It includes a first guardrail with a protective shell fixedly connected to one side. In this invention, a second guardrail is driven by a drive motor to move relative to the first guardrail, thereby adjusting the length of the guardrail and increasing its extensibility. This allows the livestock farm to flexibly adjust the space according to the growth or number of livestock, thus making more effective use of available space. Pulling the buckle upwards causes it to rotate around the top of the connecting rod three until it is disengaged from the fixed rod two, allowing the feed trough to be removed from the fixed plate for quick cleaning.

[0004] However, this device can only adjust the length laterally, not the height longitudinally. Utility Model Content

Several fixing holes 607 are opened on the side of the second pull rod 606 and the first pull rod 601 away from the main board 1. The fixing holes 607 are arranged in a linear array. During the relative movement of the first pull rod 601 and the second pull rod 606, the slide rod 602 and the limiting sleeve 604 will also slide relative to each other. The locking block 603 and the limiting block 605 will limit the slide rod 602 and the limiting sleeve 604 to prevent the slide rod 602 and the limiting sleeve 604 from separating from each other. Two rollers 9 are rotatably connected to the bottom of the first sub-plate 201.

[0027] The stretching mechanism includes a slide plate 302, which is slidably connected to the outer surface of the limiting post 203. A protruding plate 303 is fixedly connected to the end of the slide plate 302 near the first sub-plate 201, and a second sub-plate 301 is fixedly connected to the end of the slide plate 302 away from the first sub-plate 201. Two rollers 9 are rotatably connected to the bottom of the second sub-plate 301. During the relative movement of the first sub-plate 201 and the second sub-plate 301, the limiting plate 202 and the slide plate 302 also slide relative to each other. The limiting post 203 and the protruding plate 303 will limit the limiting plate 202 and the slide plate 302 to prevent the limiting plate 202 and the slide plate 302 from separating from each other.

[0028] The transmission mechanism includes a motor 401, which is fixedly connected to the rear side of the main board 1. The output end of the motor 401 is fixedly connected to a rotating shaft 402, and a gear 403 is fixedly connected to the rotating shaft 402. Two racks 404 mesh on the gear 403. When the motor 401 is started, it drives the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 drives the gear 403 to rotate. The rotation of the gear 403 drives the two racks 404 to move relative to each other. The movement of the upper rack 404 drives the second sub-plate 301 to move, and the movement of the lower rack 404 drives the first sub-plate 201 to move.

[0029] The sliding mechanism includes two sliders 501, which are fixedly connected to the opposite sides of two racks 404.

[0030] Both the first sub-plate 201 and the second sub-plate 301 have reserved openings 7 on the side away from the main plate 1. The reserved openings 7 can prevent the two racks 404 from colliding with the opposite surfaces of the first sub-plate 201 and the second sub-plate 301 when they extend or retract.

[0031] Several through slots 8 are provided on the two main boards 1. All through slots 8 pass through the limiting plate 202 and the sliding plate 302. The through slots 8 can ensure ventilation of the pen while also making it convenient for farmers to observe the poultry.

[0032] Working principle: When using this device, the motor 401 drives the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 drives the gear 403 to rotate. The rotation of the gear 403 drives the two racks 404 to move relative to each other. The movement of the upper rack 404 drives the second auxiliary plate 301 to move, and the movement of the lower rack 404 drives the first auxiliary plate 201 to move. During the relative movement of the first auxiliary plate 201 and the second auxiliary plate 301, the limiting plate 202 and the sliding plate 302 also slide relative to each other. The limiting post 203 and the protruding plate 303 limit the limiting plate 202 and the sliding plate 302 to prevent them from disengaging. At the same time, the first auxiliary plate 201 and the second auxiliary plate 301 will extend and retract synchronously, thereby adjusting the lateral length of the enclosure.

[0033] During the relative movement of the first sub-plate 201 and the second sub-plate 301, the first pull rod 601 and the second pull rod 606, which are engaged in the slot 304, will also move relative to each other. During the relative movement of the first pull rod 601 and the second pull rod 606, the sliding rod 602 and the limiting sleeve 604 will also slide relative to each other. The locking block 603 and the limiting block 605 will limit the sliding rod 602 and the limiting sleeve 604 to prevent them from disengaging. After the horizontal length of the enclosure is adjusted, the two first pull rods 601 are pulled upward. After the position is at a suitable height, the bolts are inserted through the through holes on the sides of the first sub-plate 201 and the second sub-plate 301 into the fixing holes 607 on both sides of the first pull rod 601 and the second pull rod 606 to fix the height of the first pull rod 601 and the second pull rod 606, thereby adjusting the vertical height of the enclosure.
