Description

Technical Field

[0001] This utility model belongs to the field of livestock breeding technology, and in particular relates to a liftable handcart for transferring livestock. Background Technology

[0002] In the process of livestock farming, it is often necessary to move livestock between different breeding sites. For example, livestock need to be moved to the farrowing house when they give birth, then to the nursing house after giving birth, then to the fattening house when the young are mature, and finally to the slaughter house when they are ready for slaughter. In this process, the handcart is a relatively simple and convenient way to move livestock. When using it, the handcart needs to be equipped with guardrails to prevent the livestock from escaping during the transfer.

[0003] However, existing livestock transfer handcarts are not convenient to raise or lower the guardrails during use. When the guardrails are higher than the livestock, it is difficult for the user to transfer the livestock onto the handcart, and when the guardrails are lower than the livestock, the livestock can easily escape from the handcart, resulting in economic losses. Utility Model Content

[0004] The purpose of this utility model is to provide a liftable handcart for livestock transfer. By setting up a lifting part, it solves the problem that existing livestock transfer handcarts are not convenient to raise or lower the guardrail during use. When the guardrail is higher than the livestock, it is difficult for the user to transfer the livestock onto the handcart. When the guardrail is lower than the livestock, the livestock can easily escape from the handcart, causing economic losses.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a liftable handcart for livestock transfer, comprising a handcart and several multi-stage telescopic rods fixedly connected to the top of the handcart, with guardrails fixedly connected to the top of the multi-stage telescopic rods. It also includes: a lifting part installed on the top of the handcart; and an anti-reverse part located on the right side of the handcart; wherein the left side of the anti-reverse part extends into the handcart, and the bottom of the lifting part extends into the handcart.

[0007] Furthermore, the lifting unit includes a sliding assembly installed at the bottom of the guardrail; and a rotating assembly disposed above the trolley; wherein the rotating assembly is disposed within the sliding assembly, and the bottom of the rotating assembly extends into the trolley.

[0008] Furthermore, the anti-reverse mechanism includes a transmission assembly disposed on the right side of the trolley; and a locking assembly installed inside the trolley; wherein the left side of the transmission assembly passes through the locking assembly and extends below the lifting mechanism.

[0009] Furthermore, the sliding assembly includes a primary outer shell fixedly connected to the top of the trolley, a secondary outer shell slidably connected to the inner wall of the primary outer shell, a tertiary outer shell slidably connected to the inner wall of the secondary outer shell, and a threaded sleeve rotatably connected to the inner wall of the secondary outer shell; wherein, the outer wall of the threaded sleeve is threadedly connected to the tertiary outer shell, and the telescopic adjustment of the top structure of the trolley is realized through the sliding connection of the primary, secondary, and tertiary outer shells and the threaded engagement between the threaded sleeve and the tertiary outer shell.

[0010] Furthermore, the rotating assembly includes a rotating block rotatably connected to the inner wall of the primary housing. A threaded rod is fixedly connected to the top of the rotating block, and a limiting component is provided inside the threaded rod. The rotating block penetrates the primary housing, and its bottom extends into the trolley. The limiting component includes a limiting groove formed at the top of the threaded rod, and a limiting block is fixedly connected to the top inner wall of the threaded sleeve. The limiting groove is a square groove, and the limiting block is a square block. The shape of the limiting block matches the limiting groove. The rotating block drives the threaded rod to rotate, and the square matching structure of the limiting groove and the limiting block converts the rotational motion into the lifting action of the three-stage housing.

[0011] Furthermore, the transmission assembly includes a rotating shaft rotatably connected to the inner wall of the handcart, a handle fixedly connected to the outer wall of the rotating shaft, and two bevel gears disposed on the left side of the rotating shaft; wherein, the right side of the rotating shaft extends to the outside of the handcart, the rotating shaft passes through the handle, the rotating shaft passes through the right bevel gear, the outer wall of the rotating shaft is fixedly connected to the right bevel gear, and a rotating block passes through the upper bevel gear, the outer wall of the rotating block is fixedly connected to the upper bevel gear. Through the transmission connection of the rotating shaft, the handle, and the bevel gears, the rotation of the handle can remotely drive the rotation of the rotating block, thereby realizing power transmission.

[0012] Furthermore, the locking assembly includes a limiting ring fixedly connected to the outer wall of the rotating shaft, a second limiting block slidably connected to the inner wall of the handcart, and an elastic element provided on the second limiting block; wherein, the limiting ring is a circular ring with several grooves, the bottom of the second limiting block is adapted to the limiting ring, the elastic element includes a spring telescopic rod fixedly connected to the top of the second limiting block, and a third limiting block slidably connected to the inner wall of the second limiting block; wherein, the top of the spring telescopic rod is fixedly connected to the handcart, and by means of the groove of the limiting ring and the cooperation of the second limiting block, combined with the elastic action of the spring telescopic rod, the position of the rotating shaft is locked to prevent it from rotating accidentally.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a lifting mechanism, when the height of the guardrail needs to be raised or lowered, the anti-reverse mechanism can rotate the rotating block, which in turn drives the threaded rod to rotate. When the threaded rod rotates, it will cause the secondary outer shell to slide. At the same time, under the action of the limit groove and the first limit block, the threaded sleeve will rotate. When the secondary outer shell slides, the threaded sleeve will drive the first limit block to slide. When the threaded sleeve rotates, it will drive the tertiary outer shell to slide. Thus, under the action of several multi-stage telescopic rods, the guardrail can be raised or lowered, which can prevent the guardrail from being too high and affecting the transfer, and at the same time prevent the guardrail from being too low and causing livestock to escape. This ensures the stability of the livestock transfer process.

[0015] 2. By setting an anti-reverse mechanism, when using the anti-reverse mechanism, the limit block three can be pulled, causing the limit block two to slide upwards. When the limit block two moves away from the limit ring, the limit block three can be slid to lock onto the handcart. When the limit block two slides upwards, it will exert pressure on the spring telescopic rod and generate elastic force. At this time, the limit ring will lose its restriction. Then, the handle one can be turned to drive the rotating shaft to rotate. Under the action of the two bevel gears, the rotating block will rotate. After the rotation is completed, the locking component can be reset to lock the rotating shaft again. This anti-reverse mechanism can be used to prevent the rotating shaft from rotating during use and affecting the height of the guardrail, thereby further ensuring the stability of the livestock transfer process.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The outer wall of the threaded sleeve 214 is threadedly connected to the tertiary outer shell 213. The rotating assembly 22 includes a rotating block 221 rotatably connected to the inner wall of the primary outer shell 211. A threaded rod 222 is fixedly connected to the top of the rotating block 221, and a limiting component is provided inside the threaded rod 222. The rotating block 221 penetrates through the primary outer shell 211, and the bottom of the rotating block 221 extends into the handcart 101. The limiting component includes a limiting groove 223 opened at the top of the threaded rod 222, and a limiting block 224 is fixedly connected to the top inner wall of the threaded sleeve 214. The limiting groove 223 is a square groove, and the limiting block 224 is a square block. The shape of the limiting block 224 is adapted to the limiting groove 223. By setting the lifting part 2, the guardrail 103 of the handcart 101 can be raised and lowered to avoid the guardrail 103 being too high and affecting the transfer, and at the same time to prevent the guardrail 103 from being too low and causing livestock to escape. This ensures the stability of the livestock transfer process.

[0030] The anti-reverse mechanism 3 includes a transmission assembly 31, which is located on the right side of the handcart 101; and a locking assembly 32, which is installed inside the handcart 101. The left side of the transmission assembly 31 passes through the locking assembly 32 and extends below the lifting part 2. The transmission assembly 31 includes a rotating shaft 311 rotatably connected to the inner wall of the handcart 101. A handle 312 is fixedly connected to the outer wall of the rotating shaft 311. Two bevel gears 313 are provided on the left side of the rotating shaft 311. The right side of the rotating shaft 311 extends outside the handcart 101, passing through the handle 312 and the right bevel gear 313. The outer wall of the rotating shaft 311 is fixedly connected to the right bevel gear 313. A rotating block 221 passes through the upper bevel gear 313, and the outer wall of the rotating block 221 is fixedly connected to the upper bevel gear 313. The locking component 32 includes a limiting ring 321 fixedly connected to the outer wall of the rotating shaft 311, and a second limiting block 322 slidably connected to the inner wall of the handcart 101. The second limiting block 322 is provided with an elastic element. The limiting ring 321 is a circular ring with several grooves. The bottom of the second limiting block 322 is adapted to the limiting ring 321. The elastic element includes a spring telescopic rod 323 fixedly connected to the top of the second limiting block 322, and a third limiting block 324 slidably connected to the inner wall of the second limiting block 322. The top of the spring telescopic rod 323 is fixedly connected to the handcart 101. By setting the anti-reverse part 3, the rotating shaft 311 can be anti-reverse after the height of the guardrail 103 is adjusted, so as to prevent it from rotating during use and affecting the height of the guardrail 103, thereby further ensuring the stability of the livestock transfer process.

[0031] A specific application of this embodiment is as follows: When it is necessary to raise or lower the height of the guardrail 103, the rotating block 221 can be rotated by the anti-reverse rotation part 3, which will cause the threaded rod 222 to rotate. When the threaded rod 222 rotates, it will cause the secondary outer shell 212 to slide. At the same time as the threaded rod 222 rotates, it will cause the threaded sleeve 214 to rotate under the action of the limiting groove 223 and the limiting block 224. When the secondary outer shell 212 slides, it will cause the limiting block 224 to slide through the threaded sleeve 214. When the threaded sleeve 214 rotates, it will cause the tertiary outer shell 213 to slide. Thus, under the action of several multi-stage telescopic rods 102, the guardrail 103 can be raised or lowered. 03 Sliding: When using the anti-reverse part 3, the limit block 324 can be pulled to make the limit block 222 slide upward. When the limit block 222 moves away from the limit ring 321, the limit block 324 can be slid to lock onto the handcart 101. When the limit block 222 slides upward, it will exert pressure on the spring telescopic rod 323 and generate elastic force. At this time, the limit ring 321 will lose its restriction. Then the handle 1 312 can be turned to make the rotating shaft 311 rotate. Under the action of the two bevel gears 313, the rotating block 221 will rotate. After the rotation is completed, the locking component 32 can be reset to lock the rotating shaft 311 again.
