Description

Technical Field

[0001] This utility model relates to the field of pig breeding technology, and in particular to an adjustable local breeding pig farrowing enclosure. Background Technology

[0002] In the current pig farming industry, farrowing pens are crucial facilities for ensuring the farrowing of sows and the early growth of piglets. However, traditional farrowing pens have many problems that cannot be ignored. Their space is usually fixed and cannot adapt to the needs of sows of different sizes. For larger sows, the cramped space restricts their normal activities, easily causing stress and affecting the farrowing process and postpartum recovery; while for smaller sows, an excessively large space is not conducive to their care of piglets.

[0003] Taking patent CN110447546A as an example, this patent aims to achieve spatial adjustment by changing the spatial structure of the fence through a slanted fence. However, in practice, this adjustment method requires replacing different types of fences, which is not only cumbersome and consumes a lot of manpower and time, but also may disturb sows in the breeding field due to frequent replacement of fence parts, which is not conducive to maintaining a stable living environment for sows and piglets. Therefore, we propose an adjustable local breeding pig confinement farrowing fence. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable local breeding pig farrowing enclosure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable farrowing enclosure for local breeding pigs includes a base, four sets of uprights fixed to the top of the base, a barrier between adjacent uprights, a partition door installed on one side of the barrier, a support frame installed on the top of the uprights, an adjustment mechanism installed on one side of the support frame, a separating mechanism installed on the adjustment mechanism, the separating mechanism being located on the base, and the separating mechanism being used to separate breeding pigs and piglets.

[0007] Preferably, the adjusting mechanism includes a threaded column fixed on a support frame, a first threaded sleeve connected to the threaded column by threads, a first bevel gear fixedly sleeved on the first threaded sleeve, a housing rotatably connected to the first threaded sleeve, a first adjusting rod installed on the housing, the first adjusting rod being inserted into the interior of the housing and connected to a second bevel gear.

[0008] Preferably, the first bevel gear and the second bevel gear are meshing transmissions, the housing and the inner wall of the support frame are slidably connected, and the separating mechanism is installed on the side of the housing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features an adjustment mechanism that moves a partition mechanism mounted on the side of the housing. This design allows for flexible adjustment of the space for the breeding pigs and piglets to accommodate different body sizes, solving the problem of fixed space in traditional farrowing pens. It avoids stress in large sows due to limited space and facilitates care for piglets by smaller sows. The partition mechanism also provides safety for the piglets; adjusting the height of the crossbar effectively prevents the sow from entering the piglet area during farrowing and daily activities, preventing injury and improving piglet survival rates. The device has a simple structure and can be adjusted without frequent component replacement, saving manpower and resources. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-3An adjustable local breeding pig farrowing enclosure includes a base 1, with four sets of uprights 2 fixed to the top of the base 1. A barrier 3 is fixed between adjacent uprights 2, and a partition door 4 is installed on one side of the barrier 3. A support frame 5 is installed on the top of the uprights 2, and an adjustment mechanism 6 is installed on one side of the support frame 5. A separation mechanism 7 is installed on the adjustment mechanism 6 and is located on the base 1. The separation mechanism 7 is used to separate the breeding pigs and piglets.

[0019] The adjusting mechanism 6 includes a threaded post 61 fixed to the support frame 5. A first threaded sleeve 62 is threadedly connected to the threaded post 61. A first bevel gear 63 is fixedly sleeved on the first threaded sleeve 62. A housing 64 is rotatably connected to the first threaded sleeve 62. A first adjusting rod 65 is installed on the housing 64. The first adjusting rod 65 is inserted into the interior of the housing 64 and connected to a second bevel gear 66. The first bevel gear 63 and the second bevel gear 66 are meshed and driven. The housing 64 is slidably connected to the inner wall of the support frame 5. The separating mechanism 7 is installed on the side of the housing 64. The separating mechanism 7 includes a movable frame 71 fixed to the side of the housing 64. A fixed rod 72 is fixed inside the movable frame 71. A second threaded sleeve 73 is installed on the top of the movable frame 71. A second adjusting rod 74 is threadedly connected inside the second threaded sleeve 73. The bottom of the second adjusting rod 74 is rotatable. A crossbar 75 is connected and sleeved on a fixed rod 72. There are several sets of fixed rods 72. The crossbar 75 and the fixed rod 72 are slidably connected. An adjustment mechanism is set up to drive the separation mechanism installed on the side of the shell to move. This design can flexibly adjust the size of the activity area for breeding pigs and piglets according to the size of the sow, solving the problem that the space of the traditional farrowing pen is fixed and cannot adapt to sows of different sizes. It avoids stress reactions caused by small space for large sows and makes it easier for small sows to care for piglets. At the same time, the design of the separation mechanism provides safety for piglets. Adjusting the height of the crossbar can effectively prevent the sow from entering the piglet activity area during farrowing and daily activities, preventing the sow from crushing the piglets and improving the survival rate of piglets. The device has a simple structure and can be adjusted without frequent replacement of parts, saving manpower and resources and is very convenient.

[0020] When it is necessary to adjust the size of the activity area for breeding pigs and piglets, the farmer rotates the first adjusting rod 65. The first adjusting rod 65 drives the connected second bevel gear 66 to rotate. The second bevel gear 66 meshes with the first bevel gear 63, causing the first bevel gear 63 to rotate accordingly. Because the first bevel gear 63 is fixedly sleeved on the first threaded sleeve 62, the first threaded sleeve 62 will rotate and move on the threaded post 61. Since the housing 64 is rotatably connected to the first threaded sleeve 62 and slidably connected to the inner wall of the support frame 5, the movement of the first threaded sleeve 62 will cause the housing 64 to slide along the inner wall of the support frame 5. The separating mechanism 7 is installed on the side of the housing 64. Ultimately, the separation mechanism 7 is moved, thereby changing the size of the activity area for breeding pigs and piglets. After the sow gives birth, in order to prevent the sow from crushing the piglets, the height of the crossbar 75 in the separation mechanism 7 needs to be adjusted. The farmer rotates the second adjusting rod 74, which moves up and down within the second threaded sleeve 73 via threaded transmission. Because the bottom of the second adjusting rod 74 is rotatably connected to the crossbar 75, and the crossbar 75 is sleeved on the fixed rod 72 and can slide, the crossbar 75 will slide on the fixed rod 72 as the second adjusting rod 74 moves up and down, thereby adjusting the height of the crossbar 75, forming an effective protective barrier for the piglets and preventing the sow from entering the piglet activity area.

[0021] In summary, compared to existing technologies, this utility model features an adjustment mechanism that moves the partition mechanism installed on the side of the housing. This design allows for flexible adjustment of the space for the activity areas of breeding pigs and piglets according to the sow's size, solving the problem of fixed space in traditional farrowing pens that cannot accommodate sows of different sizes. It avoids stress in large sows due to limited space and facilitates care for piglets by smaller sows. Furthermore, the partition mechanism provides safety for piglets; adjusting the height of the crossbar effectively prevents the sow from entering the piglet activity area during farrowing and daily activities, preventing injury to piglets and improving their survival rate. The device has a simple structure and can be adjusted without frequent component replacement, saving manpower and resources.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
