Description
Technical Field
[0001] This application belongs to the technical field of animal husbandry, and more specifically, relates to a gate for a restraining pen. Background Technology
[0002] Pig farming is an agricultural production activity. In order to reduce the number of boars and improve the conception rate, farrowing rate and offspring viability of sows, artificial insemination of sows is necessary.
[0003] To ensure the efficiency of artificial insemination and avoid harming the sow, the sow should be placed in a gestation crate before artificial insemination to improve the efficiency of the process.
[0004] The existing limit bars have the following main drawbacks: the locking structure is complex and the opening and closing operations are inconvenient; the limit bars are generally set in rows, and each gate needs to be controlled individually, which cannot achieve unified control. Summary of the Invention
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a gate for a limit barrier. The technical solution adopted in this application is: A gate for a limiting barrier includes a gate body, a first connecting plate, and a first connecting shaft. The first connecting plate is rotatably mounted on the first connecting shaft, and the gate body is mounted on the first connecting plate. It also includes a locking mechanism, which includes a locking sleeve and a locking pin. The locking sleeve is arranged vertically, and the locking pin is movably disposed within the locking sleeve. Both the locking sleeve and the locking pin are located above the first connecting plate, and the first connecting plate has a locking hole into which the locking pin can be inserted.
[0006] Preferably, the gate for the limit barrier also includes a control mechanism, which includes a control seat, a control shaft, and a control chain. The control shaft is rotatably mounted on the control seat, and the control chain is located between the control shaft and the locking pin and is tightened by the control shaft and the locking pin.
[0007] Preferably, the control mechanism further includes a rocker arm, the inner end of which is fixedly mounted on the control shaft, and the control chain is located between the outer end of the rocker arm and the top of the locking pin.
[0008] Preferably, the control mechanism further includes a buffer spring, which is disposed between the control chain and the swing arm and is tensioned by the control chain and the swing arm.
[0009] Preferably, the locking mechanism further includes a locking cover, a pin, and a mounting plate. The mounting plate is rotatably mounted on the pin, and the locking cover is located at the lower end of the mounting plate. The locking cover can be rotated to the lower opening of the locking sleeve.
[0010] Preferably, the side of the mounting plate is also provided with a limiting part, and the locking cover rotates to the lower opening of the locking sleeve, with the limiting part abutting against the side of the locking sleeve.
[0011] Preferably, the gate for the limiting barrier also includes a second connecting plate and a second connecting shaft. The second connecting shaft passes through the second connecting plate and is rotatably mounted on the second connecting plate. The second connecting shaft is fixedly mounted on the gate body, and the rotation axis of the second connecting shaft and the first connecting shaft are on the same straight line.
[0012] Preferably, the gate for the limit barrier also includes a gate post, which is arranged vertically, and the first connecting shaft and the second connecting plate are both fixedly arranged on the side of the gate post.
[0013] Preferably, the cross-section of the first connecting plate is semi-circular, and the gate body is located on the outer edge of the first connecting plate.
[0014] Preferably, the upper end face of the first connecting plate is further provided with a limiting protrusion, which is located on the outside of the locking hole.
[0015] The advantages of this utility model are as follows: The gate body is mounted on the first connecting plate, and the gate body is linked with the first connecting plate. The first connecting plate rotates around the first connecting shaft, which drives the gate body to rotate and adjusts the angle of the gate body, thereby realizing the three states of the gate body opening outward, closing, and opening inward in sequence. The locking pin is movably located above the first connecting plate. When the gate body is closed, the locking hole rotates to the position directly below the locking pin, and the locking pin is inserted into the locking hole, restricting the first connecting plate from continuing to rotate and locking the angle of the gate body. When the control shaft rotates forward, it can simultaneously drive multiple control chains to wind around the control shaft, causing multiple locking pins to move upward at the same time. The locking pins slide out of the locking holes, and the gate bodies in the same row are unlocked synchronously, making operation convenient. When the control shaft rotates in the reverse direction, it can simultaneously drive multiple control chains to be released outward from the control shaft. Under the action of gravity, the locking pins move downward at the same time and insert into the locking holes, locking the angle of the gate body. Attached Figure Description

Detailed Implementation
[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0020] The barrier gate for the limit bar provided in the embodiments of this application will now be described.
[0021] Example like Figures 1 to 3 As shown, a gate for a limiting barrier includes a gate body 1, a first connecting plate 11, and a first connecting shaft 21. The first connecting plate 11 is rotatably mounted on the first connecting shaft 21, and the gate body 1 is mounted on the first connecting plate 11. It also includes a locking mechanism 3, which includes a locking sleeve 31 and a locking pin 32. The locking sleeve 31 is arranged vertically, and the locking pin 32 is movably disposed within the locking sleeve 31. Both the locking sleeve 31 and the locking pin 32 are located above the first connecting plate 11, and the first connecting plate 11 has a locking hole into which the locking pin 32 can be inserted.
[0022] The gate body 1 is mounted on the first connecting plate 11. The gate body 1 is linked with the first connecting plate 11. The first connecting plate 32 rotates around the first connecting shaft 21, which drives the gate body 1 to rotate and adjusts the angle of the gate body 1, thereby realizing the three states of the gate body 1 opening outward, closing, and opening inward in sequence. The locking pin 41 is movably mounted above the first connecting plate 32. When the gate body 1 is closed, the locking hole 42 rotates to the position directly below the locking pin 41, and the locking pin 41 is inserted into the locking hole, restricting the first connecting plate 11 from continuing to rotate and locking the angle of the gate body 1.
[0023] The barrier gate also includes a control mechanism 4, which comprises a control base 41, a control shaft 42, and a control chain 43. The control shaft 42 is rotatably mounted on the control base 41, and the control chain 43 is located between the control shaft 42 and the locking pin 32, and is tensioned by the control shaft 42 and the locking pin 32. Alternatively, the control shaft 42 and the locking pin 32 can be connected by a rope.
[0024] When the control shaft 42 rotates in the forward direction, it can simultaneously drive multiple control chains 43 to wind around the control shaft 42, causing multiple locking pins 41 to move upward simultaneously. The locking pins 41 slide out of the locking holes, and the gate bodies 1 in the same row are unlocked synchronously, which is convenient to operate. When the control shaft 42 rotates in the reverse direction, it can simultaneously drive multiple control chains 43 to be released outward from the control shaft 42. Under the action of gravity, the locking pins 41 move downward simultaneously and insert into the locking holes, locking the angle of the gate body 1.
[0025] In this embodiment, the outer end of the control shaft 42 is also provided with an operating handle 421, which can conveniently drive the control shaft 42 to rotate.
[0026] The control mechanism 4 also includes a rocker arm 44, the inner end of which is fixed on the control shaft 42, and the control chain 43 is located between the outer end of the rocker arm 44 and the top of the locking pin 32.
[0027] By setting the rocker arm 44, the rotation radius is increased. The locking pin 41 moves the same distance, and the control shaft 42 needs to rotate at a smaller angle, making operation more convenient.
[0028] The control mechanism 4 also includes a buffer spring 45, which is located between the control chain 43 and the swing arm 44 and is tensioned by the control chain 43 and the swing arm 44.
[0029] The rotation of the control shaft 42 causes the buffer spring 45 between the control chain 43 and the rocker arm 44 to provide buffering. The tension of the control chain 43 changes gradually, making the control chain 43 less likely to break and ensuring high reliability.
[0030] The locking mechanism 4 also includes a locking cover 46, a hook pin 47, and a hanging plate 48. The hanging plate 48 is rotatably hung on the hook pin 47, and the locking cover 46 is located at the lower end of the hanging plate 48. The locking cover 46 can be rotated to the lower opening of the locking sleeve 31, and the locking pin 41 is attached to the locking cover 46 and cannot fall further. The gate body 1 can rotate freely. The state of each individual gate body 1 can be controlled separately through the locking cover 46.
[0031] The side of the hanging plate 48 is also provided with a limiting part 481. When the locking cover 46 is rotated to the lower opening of the locking sleeve 31, the limiting part 481 abuts against the side of the locking sleeve 31. At this time, the locking cover 46 is set in the horizontal direction, forming accurate positioning with high reliability.
[0032] The barrier gate also includes a second connecting plate 22 and a second connecting shaft 12. The second connecting shaft 12 passes through the second connecting plate 22 and is rotatably mounted on the second connecting plate 22. The second connecting shaft 12 is fixedly mounted on the barrier gate body 1. The rotation axis of the second connecting shaft 12 and the first connecting shaft 21 are on the same straight line to ensure that the barrier gate body 1 can rotate smoothly.
[0033] The barrier gate also includes a gate post 2, which is set vertically. The first connecting shaft 21 and the second connecting plate 22 are both fixedly set on the side of the gate post 2.
[0034] The cross-section of the first connecting plate 11 is semi-circular, and the gate body 1 is located on the outer edge of the first connecting plate 11, which is convenient for processing.
[0035] The upper end face of the first connecting plate 11 is also provided with a limiting protrusion 13, which is located on the outside of the locking hole.
[0036] In this embodiment, the upper part of the gate body 1 is also provided with an insemination door 14, which is hinged to the gate body 1; opening the insemination door 14 facilitates the insemination operation.
[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
