Description

Technical Field

[0001] The utility model relates to the technical field of livestock breeding, in particular to a welfare farrowing crate for sows. Background Art

[0002] With the development of the livestock industry, farrowing crates for sows have become common equipment in pig farms. The existing farrowing crates for sows are applicable during the period of sow farrowing, providing a clean and comfortable environment, improving the survival rate of piglets, and also used to separate sows and piglets, effectively avoiding the death of piglets caused by being crushed by sows. However, the space of the farrowing crate is narrow, which is not conducive to the movement of sows and will have a certain impact on the fattening efficiency and psychological state of sows.

[0003] Therefore, a welfare farrowing crate for sows that solves the above problems is needed. Summary of the Utility Model

[0004] The utility model provides a welfare farrowing crate for sows. The first side positioning fence adopts an openable structure, increasing the activity space of sows, being conducive to the fattening, mental health and postpartum recovery of sows. At the same time, piglets can be restricted in the piglet restraint area, avoiding the trampling and extrusion of piglets by sows during the movement of sows and improving the survival rate of piglets.

[0005] The technical solution of the utility model is realized as follows:

[0006] The welfare farrowing crate for sows includes a horizontally arranged feces leakage board, and a pair of vertically arranged side baffles and end baffles are fixedly installed on the feces leakage board. The two end baffles are arranged between the two side baffles and are connected end to end with the two side baffles.

[0007] Two parallel first side positioning fences and second side positioning fences are also fixedly installed on the feces leakage board. The first side positioning fence and the second side positioning fence are both vertically arranged between the two end baffles. A vertically arranged first positioning door is hinged at both ends of the first side positioning fence, and each first positioning door is constrained and installed on the first side positioning fence through a first locking assembly. An end positioning fence and a front door are installed between the first side positioning fence and the second side positioning fence. A piglet passage is formed between the end positioning fence and the adjacent end baffle. A second positioning door is slidably installed horizontally at a position of the piglet passage close to the second side positioning fence. A second locking assembly is arranged between the second positioning door and the adjacent end baffle. A piglet restraint area is formed among the second positioning door, the second side positioning fence, the adjacent side baffle and the two end baffles.

[0008] A limiting component for limiting the opened first positioning door is provided on each of the end baffles. When the two first positioning doors are opened, a sow activity area is formed between the end positioning bar, the second side positioning bar, the front door, the two first positioning doors, and the adjacent side baffles.

[0009] As a preferred technical solution, each first locking component includes two horizontally arranged fixing plates. The lower fixing plate is fixedly installed on the first side positioning bar. Two connecting plates are fixedly installed between the two fixing plates. A vertically arranged locking rod is fixedly installed on each first positioning door. First limiting grooves for blocking the corresponding locking rod from moving towards the second side positioning bar are provided on the two fixing plates. A limiting plate is hinged between the two fixing plates. The limiting plate is arranged between the two connecting plates. A second limiting groove for blocking the corresponding locking rod from moving away from the second side positioning bar is provided on the limiting plate. The free end of each limiting plate abuts against the corresponding connecting plate away from the second side positioning bar. A first compression spring is constraint-installed between the free end of each limiting plate and the first side positioning bar.

[0010] As a preferred technical solution, the second locking component includes a first hook plate and a second hook plate. One end of each of the first hook plate and the second hook plate is a hook-shaped clamping portion. The other end of the first hook plate is fixedly installed on the end baffle adjacent to the second positioning door. The other end of the second hook plate is fixedly installed on the second positioning door. An elastic connecting plate is provided between the fixed end of the second hook plate and the clamping portion. A second compression spring is provided between the second hook plate and the second positioning door.

[0011] As a preferred technical solution, each limiting component includes two support plates fixedly installed on the corresponding end baffle. A plurality of horizontally arranged blocking rods are fixedly installed on each first positioning door. A blocking block for blocking the corresponding blocking rod from moving in the reverse direction is hinged between the corresponding two support plates. A limiting column is fixedly installed on the top of each blocking block. The bottom of each limiting column abuts against the top of the corresponding two support plates. A guiding inclined surface is provided on one side of each blocking block away from the corresponding end baffle. The lower end of each guiding inclined surface extends towards the adjacent end baffle.

[0012] As a preferred technical solution, a heightening railing is fixedly installed on the side baffle close to the first side positioning bar. A connecting rod is fixedly installed between the heightening railing and the first side positioning bar.

[0013] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] Since the sow welfare farrowing bed includes two first positioning doors, when using this farrowing bed, after the piglets finish suckling, the piglets can be driven through the piglet passage into the piglet restraint area. Then, close the second positioning door to restrain the piglets in the piglet restraint area, avoiding trampling and squeezing of the piglets by the sow during its movement, and improving the survival rate of the piglets. At the same time, the two first positioning doors can be opened, and the two first positioning doors are limited by the limiting component to prevent the first positioning door from moving towards the direction close to the second side positioning bar. At this time, the sow can move in the sow activity area. Compared with the traditional farrowing bed, the first side positioning bar of this farrowing bed adopts an openable structure, increasing the activity space of the sow, which is beneficial to the fattening, mental health and postpartum recovery of the sow.

[0015] Since the sow welfare farrowing bed includes a first locking component, when the piglets are in the suckling state, under the action of the first compression spring, the free end of the limiting plate abuts against the connecting plate. At the same time, the locking rod is limited by the first limiting groove on the fixing plate and the second limiting groove on the limiting plate, realizing the positioning of the first positioning door on the first side positioning bar, thereby restraining the sow between the first side positioning bar, the second side positioning bar, the front door and the end positioning bar, facilitating piglet suckling while avoiding trampling and squeezing of the piglets by the sow.

[0016] If it is necessary to open the first positioning door, the free end of the limiting plate can be rotated to move away from the first positioning door. As the limiting plate rotates, the locking rod disengages from the limit of the second limiting groove, and the first positioning door ends its locking and can be rotated away from the first positioning bar.

[0017] Since the sow welfare farrowing bed includes a second locking component, the cooperation of the engaging parts of the first hook plate and the second hook plate locks the second positioning door to the adjacent end baffle, thus forming a piglet restraint area, reducing the activity range of the piglets and facilitating the breeding personnel to grab the piglets for operations such as disinfection and vaccination.

[0018] If it is necessary to open the second positioning door, just pull the engaging part of the second hook plate away from the first hook plate, the elastic connecting plate deforms, and the engaging part of the second hook plate disengages from the lock of the engaging part on the first hook plate, that is, the second positioning door is unlocked.

[0019] Since the sow welfare farrowing crate includes a limiting component, during the opening process of the first positioning door, the blocking rod on the first positioning door abuts against the guiding inclined surface and pushes the blocking block to rotate upward. Further, the blocking rod moves between the blocking block and the adjacent end baffle. At this time, the first positioning door is in the open state. Due to the setting of the limiting column, the blocking block cannot rotate in the reverse direction, so that the first positioning door cannot rotate towards the direction close to the first side positioning fence, thus achieving the function of limiting the opened first positioning door. Furthermore, when the sow is moving in the sow activity area, it is avoided that the first positioning door moves towards the direction close to the first side positioning fence and causes harm to the sow. The opened first positioning door can act as a blocking railing on the side of the sow activity area to prevent the sow from disengaging from the farrowing crate from the side of the sow activity area.

[0020] When it is necessary to close the first positioning door, only need to rotate the blocking block upward so that the lower end of the blocking block is higher than the corresponding blocking rod. At this time, the first positioning door is unlocked. BRIEF DESCRIPTION OF THE DRAWINGS
