Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, and in particular to a multifunctional farrowing bed. Background Technology

[0002] With the rapid development of modern, large-scale, and intensive pig farming, improving piglet survival rates and sow productivity has become a core objective in pig farming management. During farrowing and lactation, piglets face numerous survival risks. One of the most prominent problems is that sows, due to loss of control while lying down, turning over, or nursing, can crush or injure piglets, leading to frequent cases of abnormal deaths such as piglets being crushed or trampled to death, severely impacting farming efficiency. Traditional farrowing crate designs typically restrict the sow's activity range using gestation crates to reduce direct harm to piglets. However, this design has significant shortcomings in practical application: on the one hand, sows may still insert their heads or parts of their bodies into the piglets' activity area while nursing or resting, increasing the risk of piglets being crushed; on the other hand, piglets, driven by their instinct to find milk, often actively enter the sow's living area, further exacerbating safety hazards. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a multifunctional farrowing crate that solves the technical problem of piglets being easily crushed in existing farrowing crates.

[0004] According to embodiments of the present invention, the present invention adopts the following technical solution:

[0005] A multifunctional birthing bed, comprising:

[0006] The farrowing crate body has a sow living area located at its center and piglet living areas located on both sides of the sow living area;

[0007] The protective component includes a mounting base, a protective door, and a positioning boss. The two opposite ends of the mounting base are respectively connected to the piglet living area and the sow living area. The protective door is rotatably provided at the end closer to the sow living area. The positioning boss is located on the rotation path of the protective door. Both the protective door and the positioning boss are provided with clearance openings so that when the protective door abuts against the positioning boss under the action of external force, the clearance openings are partially opened.

[0008] The mounting base is equipped with a safety component. When the protective door is in a protective posture under the action of external force, it is used to activate the safety component to close the end of the mounting base near the sow living area, so as to drive the piglets from the sow living area into the mounting base and / or the piglet living area.

[0009] Preferably, the security component includes:

[0010] Positioning rod;

[0011] A sleeve is rotatably mounted on the positioning boss. The sleeve has an inclined groove. The positioning rod has a positioning protrusion, and the positioning protrusion is slidably mounted on the inclined groove.

[0012] The safety door is connected to the sleeve.

[0013] Preferably, a limiting rod is provided on one side of the positioning rod, a first compression spring is sleeved on the limiting rod, and the top end of the positioning rod is connected to the limiting rod.

[0014] Preferably, a partition is provided between the sow living area and the protective door, and the far end of the safety door is attached to the partition.

[0015] Preferably, the mounting base is provided with a through groove communicating with the piglet living area, and a movable plate is slidably provided in the through groove. The movable plate extends out of the mounting base and fits against the mounting door.

[0016] Preferably, the movable plate has a walking plate at one end near the piglet living area, and the walking plate can be selectively connected to or separated from the movable plate.

[0017] Preferably, a slide bar is provided between the movable plate and the traveling plate, and a second compression spring is sleeved on the slide bar.

[0018] Preferably, one end of the walking plate abuts against the slide rod, and the other end is rotatably hinged to the mounting base.

[0019] Preferably, a connecting channel is provided on one side of the farrowing crate body for connecting the two piglet living areas.

[0020] Compared with the prior art, the present invention has the following beneficial effects: the rotatable and limit-positioned protective door provides a solid physical barrier for piglets, effectively preventing the sow from crushing or injuring the piglets when lying down; in addition, through the linkage between the safety component and the protective door, the safety component is automatically triggered to close the passage when the sow lies down, which can actively drive the piglets still in the sow area to the relatively safe mounting seat or the piglet living area.

[0024] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the technical solutions of this invention are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0025] See Figures 1 to 6 This invention provides a multifunctional delivery bed, comprising:

[0026] The farrowing crate body 1 has a sow living area 2 located at its center and piglet living areas 3 located on both sides of the sow living area 2.

[0027] The protective assembly includes a mounting base 4, a protective door 5, and a positioning boss 6. The two opposite ends of the mounting base 4 are respectively connected to the piglet living area 3 and the sow living area 2. The protective door 5 is rotatably provided at the end closer to the sow living area 2. The positioning boss 6 is located on the rotation path of the protective door 5. Both the protective door 5 and the positioning boss 6 are provided with a clearance opening 51 so that when the protective door 5 abuts against the positioning boss 6 under the action of external force, the clearance opening 51 is partially opened.

[0028] The mounting base 4 is equipped with a safety component. When the protective door 5 is in a protective posture under the action of external force, it is used to activate the safety component to close the end of the mounting base 4 near the sow living area 2, so as to drive the piglets from the sow living area 2 into the mounting base 4 and the piglet living area 3.

[0029] In this embodiment, the farrowing crate body 1 is divided into three parts: a sow living area 2 in the central area and piglet living areas 3 on both sides. This layout meets the natural needs of sows for farrowing and lactation, while separating the piglet activity area from the sow's. A protective component is provided between the piglet living area 3 and the sow living area 2. The protective component includes a mounting base 4, whose two ends are respectively connected to the piglet living area 3 and the sow living area 2, serving as the necessary passage for piglets to enter and exit the two areas. A protective door 5 is rotatably mounted on the mounting base 4, located at the end of the mounting base 4 closest to the sow area and tilted at a 45° angle towards the sow living area 2. The mounting base 4 has two symmetrically arranged positioning protrusions 6, located on the rotation path of the protective door 5. Both the protective door 5 and the positioning protrusions 6 have clearance openings 51. Under normal conditions, the protective door 5 is in a free state. When the sow lies down to one side, it will squeeze the protective door 5, causing the protective door 5 to rotate and abut against the positioning protrusions 6. At this time, the protective door 5... The clearance openings 51 of the door 5 and the positioning protrusion 6 are partially aligned, forming a small, restricted passage that pushes the piglet's body into the mounting base 4. The piglet's head can pass through the clearance opening 51, but its body cannot completely pass through, preventing the piglet from being completely exposed to the danger zone. However, it effectively prevents the sow's body from continuing to press downwards, thus preventing the sow from crushing or trampling the piglet. In addition, when the protective door 5 is in a protective posture due to external force (sow squeezing), the safety components on the mounting base 4 will be triggered in conjunction, automatically closing the end of the mounting base 4 closest to the sow's living area 2. This will drive the piglet into the relatively safe interior of the mounting base 4 or the piglet's living area 3, changing the traditional passive protection into active protection. It is no longer a simple physical isolation, but an active, responsive safety system. The sow's approach behavior (potential danger) directly triggers the protection mechanism, forcibly separating the piglet from the sow, greatly reducing the risk of the piglet being crushed to death. This multi-functional protective farrowing crate can significantly improve the survival rate of piglets.

[0030] The security components include:

[0031] Positioning rod 7;

[0032] Sleeve 8 is rotatably mounted on the positioning boss 6. Sleeve 8 is provided with inclined groove 81. Positioning rod 7 is provided with positioning protrusion 71. Positioning protrusion 71 is slidably mounted on inclined groove 81.

[0033] Install the door and connect it to the sleeve 8.

[0034] In this embodiment, the positioning rod 7 is provided with a positioning protrusion 71, and the sleeve 8 is rotatably mounted on the positioning boss 6. A groove 81 is provided on the sleeve wall. The positioning protrusion 71 on the positioning rod 7 is slidably mounted within the groove 81 of the sleeve 8, forming a sloping slider mechanism. Two safety doors 82 are symmetrically arranged on the two positioning bosses 6 and directly connected to the sleeve 8. When the protective door 5 is closed and abuts against the positioning boss 6 (i.e., in a protective posture), it applies pressure to push the positioning rod 7 to move linearly. The linear movement of the positioning rod 7 forces the positioning protrusion 71 to slide within the groove 81. Since the groove 81 is inclined, the sliding... The linear motion of the block is converted into the rotational motion of the sleeve 8. The rotation of the sleeve 8 causes the two safety doors 82 connected to it to rotate. The two mounting doors rotate inward, pushing the piglets located in the clearance opening 51 into the mounting seat 4, thereby closing the end of the mounting seat 4 near the sow's living area 2. According to the inclination design of the inclined groove 81, it has a certain degree of self-locking. When the safety door 82 is closed, the piglets arch against the safety door 82 from inside the mounting seat 4. It is difficult for the force to be transmitted in the opposite direction through the sleeve 8 and the inclined groove 81 to open the protective door 5, further enhancing the stability of the isolation state. The safety door 82 will not open when the sow has not gotten up.

[0035] A limiting rod 9 is provided on one side of the positioning rod 7, and a first compression spring 10 is sleeved on the limiting rod 9. The top end of the positioning rod 7 is connected to the limiting rod 9.

[0036] In this embodiment, a limiting rod 9 is provided on one side of the positioning rod 7, and the top end of the positioning rod 7 is connected to the limiting rod 9, which forcibly restricts the positioning rod 7 to move only up and down, ensuring that the positioning protrusion 71 on it can slide in the inclined groove 81 of the sleeve 8. A first compression spring 10 is sleeved on the limiting rod 9. When the protective door 5 is opened, that is, after the sow no longer applies pressure, the positioning rod 7 and the safety door 82 driven by it will automatically return to the initial open state without manual intervention.

[0037] A partition 11 is provided between the sow living area 2 and the safety door 82, and the far end of the safety door 82 is attached to the partition 11.

[0038] In this embodiment, a partition 11 is provided between the sow living area 2 and the safety door 82. When the safety door 82 is in a free state, the far end of the safety door 82 is perpendicularly attached to the partition 11. This is to prevent piglets from being completely located in the sow living area 2. The partition 11 blocks them from being close to the avoidance opening 51, so that the sow will not be directly squeezed when she lies down.

[0039] The mounting base 4 is provided with a through groove 12 that communicates with the piglet living area 3. A movable plate 13 is slidably provided in the through groove 12. The movable plate 13 extends out of the mounting base 4 and fits against the safety door 82.

[0040] In this embodiment, a through groove 12 connected to the piglet living area 3 is provided on the mounting base 4. A movable plate 13 is slidably provided above the through groove 12. Part of the movable plate 13 extends out of the mounting base 4 and is respectively attached to two safety doors 82. When the two safety doors 82 rotate inward, the movable plate 13 can be moved backward and the through groove 12 can be opened. Piglets can fall into the through groove 12 and pass through to the piglet living area 3. In the protective state, the piglets can be actively transferred to avoid potential dangers.

[0041] The movable plate 13 is provided with a walking plate 14 at one end near the piglet living area 3. The walking plate 14 can be selectively connected to or separated from the movable plate 13.

[0042] In this embodiment, a walking plate 14 is provided at the end of the moving plate 13. The walking plate 14 is used to at least partially close the channel 12 to prevent piglets from accidentally entering the channel 12 during feeding and being unable to eat the mother's milk. When the moving plate 13 moves backward, it can knock the walking plate 14 open to separate the two and expose more of the opening so that the piglets can return to the piglet living area 3 through the channel 12.

[0043] A slide bar 15 is provided between the movable plate 13 and the walking plate 14, and a second compression spring 16 is sleeved on the slide bar 15.

[0044] In this embodiment, a slide bar 15 is provided between the moving plate 13 and the traveling plate 14. The two ends of the slide bar 15 abut against the moving plate 13 and the traveling plate 14 respectively, so that when the moving plate 13 moves backward, the traveling plate 14 is separated from it and exposed to the through groove 12. A second compression spring 16 is sleeved on the slide bar 15 so that when the external force disappears, the traveling plate 14 and the moving plate 13 automatically return to their original positions.

[0045] One end of the walking plate 14 abuts against the slide bar 15, and the other end is rotatably hinged to the mounting base 4.

[0046] In this embodiment, the walking plate 14 is inclinedly disposed in the mounting base 4, with its lower end rotatably hinged to the mounting base 4 and its upper end abutting against the slide rod 15. By pushing the moving plate 13, the walking plate 14 rotates around the hinge point, thereby exposing the through groove 12.

[0047] The farrowing crate body 1 has a connecting channel 17 on one side for connecting the two piglet living areas 3.

[0048] In this embodiment, a connecting channel 17 is provided on one side of the farrowing crate body 1 to connect two piglet living areas 3, so that when the sow lies in different directions, the piglets can go to the corresponding piglet living area 3 to nurse through the connecting channel 17.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
