Description

Technical Field

[0001] This utility model relates to the field of pig weighing technology, specifically to a pig weighing and unloading device. Background Technology

[0002] Modern pig farming generally adopts large-scale fence farming. As pigs grow, in order to understand their growth information in a timely manner, they are usually weighed regularly. However, pigs are living animals, and it is very difficult to weigh them by binding them or driving them onto an open weighbridge. Often, multiple people need to operate at the same time.

[0003] A search revealed a utility model patent with publication number CN215573286U, which discloses a pig weighing device. The device includes a base plate, wheels and steering wheels located below the base plate, a weighbridge located above the base plate, and a fence assembly on the weighbridge. The fence assembly includes symmetrically arranged fences and an entrance gate for entering the fence. The entrance gate includes a rotating shaft with three sets of gate stops arranged in a circular array along its axis. One end of the rotating shaft also has a ratchet mechanism to prevent the entrance gate from reversing. This practical weighing device uses an entrance gate that can rotate in one direction without reversing. It rotates automatically using the force of the pig's forward movement and uses the ratchet mechanism to achieve a reversible locking effect. This greatly solves the problem of pigs leaving the weighing cage after entering it, and eliminates the need for dedicated control of the entrance gate's opening and closing. This makes the weighing operation more efficient and convenient to use.

[0004] Although the aforementioned patent uses a ratchet mechanism to achieve a reversible locking effect and address the issue of pigs entering and leaving the weighing cage, when the device approaches the fence of the breeding base, there is no fence protection between the device's outlet and the fence opening, and there is a large space between the two. This makes it easy for pigs to be stimulated and collide with the device during the weighing process, causing them to escape between the device's outlet and the fence opening. This affects the normal operation of the entire pig weighing process and greatly increases the workload of the workers.

[0005] Therefore, it is necessary to propose a pig weighing and unloading device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a pig weighing and unloading device. Through the cooperation between the internal parts of the rotating mechanism and the internal parts of the protective mechanism, the crossbar and fence can be opened or closed on the inclined ladder by adjusting the rotation and extension of the support rod. After opening, the fence is located on both sides of the inclined ladder, which can protect the connection between the fence opening of the breeding base and the main body of the device. This facilitates the orderly movement of pigs between the main body of the device and the fence of the breeding base. This solves the problem in the prior art where there is no fence protection between the outlet of the device and the fence opening of the breeding base, and there is a large space between the two. This makes it easy for pigs to be stimulated and collide with the device during the weighing process, causing them to escape from the device outlet and the fence opening of the breeding base. This affects the normal operation of the pig weighing process and greatly increases the workload of workers.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pig weighing and unloading device, comprising a device body, inclined ladders installed on both sides of the device body, a weighbridge mechanically installed at the top of the device body, a rotating mechanism rotatably connected to both sides of the device body and located at the top of the inclined ladders, and a protective mechanism rotatably connected to one side of the rotating mechanism and extending through to the top of the inclined ladder and the device body.

[0008] The rotating mechanism includes a support rod, which is rotatably connected to the top of the inclined ladder and extends into the interior of the inclined ladder. The bottom end of the support rod is mechanically connected to a connecting rod, and the bottom end of the connecting rod is mechanically connected to a support ring, which is slidably connected to the interior of the inclined ladder. The top end of the support ring and the interior of the inclined ladder are mechanically connected to a support spring, which is sleeved with the outer wall of the connecting rod. The bottom end of the support ring is mechanically fixed with a limit post and extends into the interior of the inclined ladder.

[0009] The protective mechanism includes multiple crossbars, which are rotatably connected to one side of a support rod and extend into the interior of the support rod. A fence rail is mechanically connected between the multiple crossbars and extends through the crossbars to the top of the inclined ladder and the main body of the device. A slip ring is slidably connected inside each crossbar and located at the top of the fence rail, and is rotatably connected to the top of the fence rail via a bearing. Limiting sliders are mechanically machined at both ends of the outer wall of the slip ring and slidably connected to the inner wall of the crossbar.

[0010] Preferably, the protective mechanism further includes a connecting shaft, which is rotatably connected to the inside of the support rod and located on one side of the crossbar. A torsion spring is sleeved on the outer wall of the connecting shaft, and a fixed shaft is rotatably connected at the junction of the lower part of the fence post and the inside of the crossbar.

[0011] Preferably, the left side of the main body of the device is the outlet, the right side of the main body of the device is the inlet, and the surface of the main body of the device is provided with a display screen that is electrically connected to the weighbridge.

[0012] Preferably, the inclined ladder has a support groove inside that matches the support rod, a limiting groove inside that matches the limiting post, and a telescopic groove inside that matches the connecting rod.

[0013] Preferably, the side of the support rod is provided with a movable groove that matches the crossbar, the surface of the crossbar is provided with a swing groove that matches the fence post, and the two sides of the torsion spring are respectively connected and fixed to the support rod and the crossbar.

[0014] Preferably, the bottom end of the crossbar is provided with a connecting groove that matches the slip ring, and the connecting groove is provided with a limiting groove that matches the limiting slider. The top of the main body of the device and the top of the inclined ladder are provided with multiple positioning holes that match the fence railing.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By pushing the main body of the device to the fence entrance of the breeding base, aligning the entrance of the main body of the device with the fence entrance, and driving the pigs into the main body of the device via the inclined ladder, the staff lifts the support rod upwards. The support rod drives the support ring through the connecting rod to compress the support spring and move, so that the support rod extends out from the top of the inclined ladder. At the same time, the support ring drives the limiting post to separate from the inside of the inclined ladder, releasing the rotation limit on the support rod. The staff can then rotate the support rod, which will drive the crossbar and fence to protect the entrance and exit of the main body of the device. The pigs can then be weighed at the top of the main body of the device using a weighbridge.

[0017] 2. By lifting the support rod at the outlet, the support rod moves upward, causing the fence at the bottom of the crossbar to separate from the positioning hole at the top of the device body. This allows the support rod to rotate, moving the crossbar and fence away from the top of the device body. Simultaneously, the torsion spring inside the support rod resets, causing the connecting shaft to rotate. This rotation causes the crossbar to tilt at an angle, which in turn causes the fence to tilt synchronously via the fixed shaft and slip ring. The slip ring at the top of the fence slides inside the crossbar through a limit slider, allowing the top of the fence to swing at the top of the device body. The bottom of the fence rotates via the fixed shaft, completing the synchronous tilt with the crossbar. The bottom of the fence extends into the inclined ladder, providing protection for the crossbar and fence on both sides of the top of the inclined ladder. This protects the area between the device body and the enclosure of the breeding base, allowing pigs to be weighed and moved from above the device body to the breeding base via the inclined ladder, preventing them from escaping from the device body while using the inclined ladder.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The live pig weighing and unloading device shown includes a main body 1, inclined ladders 101 installed on both sides of the main body 1, a weighbridge 2 mechanically installed at the top of the main body 1, a rotating mechanism 3 rotatably connected to both sides of the main body 1 and located at the top of the inclined ladders 101, and a protective mechanism 4 rotatably connected to one side of the rotating mechanism 3 and extending through the inclined ladders 101 and the top of the main body 1.

[0029] The rotating mechanism 3 includes a support rod 301, which is rotatably connected to the top of the inclined ladder 101 and extends into the interior of the inclined ladder 101. The bottom end of the support rod 301 is mechanically connected to a connecting rod 302, and the bottom end of the connecting rod 302 is mechanically connected to a support ring 303, which is slidably connected into the interior of the inclined ladder 101. The top end of the support ring 303 and the interior of the inclined ladder 101 are mechanically connected to a support spring 304, which is sleeved with the outer wall of the connecting rod 302. The bottom end of the support ring 303 is mechanically fixed with a limit post 305, which extends into the interior of the inclined ladder 101.

[0030] The protective mechanism 4 includes multiple horizontal bars 401. The multiple horizontal bars 401 are rotatably connected to one side of the support rod 301 and extend into the interior of the support rod 301. The multiple horizontal bars 401 are mechanically connected to a fence bar 404, which extends through the horizontal bars 401 to the top of the inclined ladder 101 and the main body 1 of the device. A slip ring 406 is slidably connected inside the horizontal bar 401 and is located at the top of the fence bar 404. It is rotatably connected to the top of the fence bar 404 through a bearing. Limiting sliders 407 are mechanically machined at both ends of the outer wall of the slip ring 406 and are slidably connected to the inner wall of the horizontal bar 401.

[0031] Through the cooperation between the internal parts of the rotating mechanism 3 and the internal parts of the protective mechanism 4, it is easy to open or close the crossbar 401 and the fence bar 404 on the inclined ladder 101 by adjusting the rotation and extension of the support rod 301. After opening, the fence bar 404 is located on both sides of the inclined ladder 101, which can protect the connection position between the fence opening of the breeding base and the main body 1 of the device, and facilitate the orderly movement of pigs between the main body 1 of the device and the fence of the breeding base.

[0032] Refer to the instruction manual appendix Figure 1-6 The protective mechanism 4 also includes a connecting shaft 402, which is rotatably connected to the inside of the support rod 301 and located on one side of the crossbar 401. A torsion spring 403 is sleeved on the outer wall of the connecting shaft 402. A fixed shaft 405 is rotatably connected at the junction of the lower part of the fence post 404 and the inside of the crossbar 401. Through the mutual cooperation between the internal parts of the protective mechanism 4, the crossbar 401 can move, and the fixed shaft 405 can drive the fence post 404 to tilt at an angle.

[0033] Refer to the instruction manual appendix Figure 1-6The left side of the main body 1 is the outlet, and the right side of the main body 1 is the inlet. The surface of the main body 1 is equipped with a display screen that is electrically connected to the weighbridge 2. The left side of the main body 1 is the outlet, and the right side of the main body 1 is the inlet. The surface of the main body 1 is equipped with a display screen that is electrically connected to the weighbridge 2, so that the pigs can move from the right side of the main body 1 onto the main body 1 and stand on the weighbridge 2. After weighing, the pigs can be removed from the left side of the main body 1.

[0034] Refer to the instruction manual appendix Figure 1-6 The inclined ladder 101 has a support groove that matches the support rod 301 inside, a limiting groove that matches the limiting post 305 inside, and a telescopic groove that matches the connecting rod 302 inside. The limiting groove and telescopic groove inside the inclined ladder 101 that match the limiting post 305 inside facilitate the rotational limitation of the support rod 301 after the limiting post 305 is fixed inside the inclined ladder 101.

[0035] Refer to the instruction manual appendix Figure 1-6 The support rod 301 has a movable groove on its side that matches the crossbar 401, and the surface of the crossbar 401 has a swing groove that matches the fence rail 404. The torsion spring 403 is connected and fixed to the support rod 301 and the crossbar 401 on both sides respectively. The movable groove on the side of the support rod 301 that matches the crossbar 401 and the swing groove on the surface of the crossbar 401 that matches the fence rail 404 make it easy for the crossbar 401 to tilt on the support rod 301. At the same time, the tilting of the crossbar 401 makes it easy to drive the fence rail 404 to tilt synchronously.

[0036] Refer to the instruction manual appendix Figure 1-6 The bottom end of the crossbar 401 is provided with a connecting groove that matches the slip ring 406, and the connecting groove is provided with a limiting slide groove that matches the limiting slider 407. The top ends of the device body 1 and the inclined ladder 101 are provided with multiple positioning holes that match the fence bar 404. By providing multiple positioning holes that match the fence bar 404 at the top ends of the device body 1 and the inclined ladder 101, the bottom end of the fence bar 404 can be fixed to the top ends of the device body 1 and the inclined ladder 101, thereby driving the crossbar 401 to be limited and fixed at the top ends of the device body 1 and the inclined ladder 101.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-6By pushing the main body 1 of the device to the fence opening of the breeding base, aligning the entrance of the main body 1 with the fence opening, and driving the pigs into the main body 1 through the inclined ladder 101, the staff lifts the support rod 301 upwards. The support rod 301 drives the support ring 303 to compress the support spring 304 through the connecting rod 302, causing the support rod 301 to extend from the top of the inclined ladder 101. At the same time, the support ring 303 drives the limiting post 305 to separate from the inside of the inclined ladder 101, releasing the rotation limit on the support rod 301. The staff can then rotate the support rod 301, which will drive the crossbar 401 and the fence bar 404 to protect the entrance and exit of the main body 1. This allows the pigs to be weighed at the top of the main body 1 using the weighbridge 2.

[0039] Refer to the instruction manual appendix Figure 1-6 By lifting the support rod 301 at the outlet, the support rod 301 moves upward, causing the guardrail 404 at the bottom of the crossbar 401 to separate from the positioning hole at the top of the device body 1. This causes the support rod 301 to rotate, moving the crossbar 401 and the guardrail 404 away from the top of the device body 1. Simultaneously, the torsion spring 403 inside the support rod 301 resets, causing the connecting shaft 402 to rotate. The rotation of the connecting shaft 402 causes the crossbar 401 to tilt at an angle. The rotation of the crossbar 401, through the fixed shaft 405 and the slip ring 406, causes the guardrail 404 to tilt synchronously. The slip ring 406 at the top of the guardrail 404 then limits the movement. The slider 407 slides inside the crossbar 401, causing the top of the fence bar 404 to swing at the top of the main body 1 of the device via the slip ring 406, and the bottom of the fence bar 404 to rotate via the fixed shaft 405, thus tilting synchronously with the crossbar 401. The bottom of the fence bar 404 extends into the inclined ladder 101, thus protecting the crossbar 401 and the fence bar 404 on both sides of the top of the inclined ladder 101. This protects the area between the main body 1 of the device and the fence opening of the breeding base, allowing the pigs to be weighed and then moved from above the main body 1 of the device to the breeding base via the inclined ladder 101, preventing the pigs from running out of the main body 1 when passing through the inclined ladder 101.

[0040] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
