[0001] The invention belongs to the technical field of livestock fixation, and in particular relates to a fixation structure and method for livestock fixation. Background Art

[0002] Livestock refers to domesticated animals that are mainly used for human production, labor and life needs. Livestock usually include some common animals, such as cattle, sheep, pigs, chickens, ducks, etc. They can provide meat, dairy products, eggs and other food, or be used for farming, transportation and other labor. The breeding and management of livestock is an important part of agricultural production and can provide humans with rich resources and economic benefits.

[0003] When fixing pigs with the existing livestock fixing structure, the staff generally pushes the splint, and then directly clamps the two sides of the pig's body through the splint. However, since the pig's body is usually strong and has great strength, the fixing effect of the clamping plates on both sides is too simple, resulting in a poor fixing effect, which in turn affects the subsequent injection or other medical work of the staff.

The second inclined block squeezes the third inclined block and the convex rod at the top thereof to move upward, so that the convex rod drives the clamping plate to move to the outside of the support frame, thereby preventing the pig from being tripped by the clamping plate when entering the support frame at the beginning. Then, the limit plate moves toward the direction of the transmission assembly, so that the convex rod drives the two clamping plates to slide in opposite directions along the trajectories of the two inclined grooves respectively. When the grille plate abuts the skin on both sides of the pig's body, the clamping plate abuts the pig's legs and squeezes the pig's legs to fit with the outer wall of the grille plate, so that the pig's body and legs are fixed at the same time, thereby achieving a good fixation effect.

[0022] The present invention improves the fixation effect on livestock by arranging the coordination of structures such as a rotating component, a transmission component and a clamping component. The first bevel gear cooperates with the transmission component, so that the transmission component drives the two bevel gear plates to rotate in opposite directions, thereby causing the two support plates to rotate in opposite directions. Subsequently, the two support plates respectively drive the two groups of first round rods and second round rods to rotate in opposite directions, thereby reducing the gap in the middle of the support plates. When the outer walls of the first round rods and the second round rods are in contact with the skin at the pig's neck, the support plates stop rotating, thereby limiting the pig's neck, thereby achieving a better fixation effect.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 11 As shown, the present invention provides a fixing structure for fixing livestock, comprising a support frame 1, a motor 2 is fixedly connected to the top of the support frame 1, a push plate assembly 3 is arranged inside the support frame 1, a moving assembly 4 is movably connected inside the support frame 1, a pair of clamping plates 5 are movably connected inside the support frame 1, a convex rod 6 is fixedly connected to the bottom of the clamping plate 5, a rotating assembly 7 and a transmission assembly 8 are movably connected to one side of the support frame 1, two bevel gear plates 9 facing oppositely are arranged on one side of the support frame 1 close to the transmission assembly 8, and clamping assemblies 10 are fixedly connected to the opposite sides of the two bevel gear plates 9;

[0037] The push plate assembly 3 includes a grid plate 301 movably connected to both sides of the support frame 1 .

[0038] The above scheme is adopted: the first inclined block 401 and the second inclined block 402 are driven to move toward each other through the grille plate 301, so that the second inclined block 402 squeezes the third inclined block 405 and the convex rod 6 at its top to move upward, and then the clamping plate 5 is driven to move to the outside of the support frame 1 through the convex rod 6, and then the first inclined block 401 abuts against the inclined surface of the limiting plate 403, and squeezes the limiting plate 403 to move in the direction of the transmission component 8, thereby driving the two convex rods 6 to slide in opposite directions along the trajectories of the two inclined grooves 404, and then the two clamping plates 5 slide in opposite directions. When the grille plate 301 abuts against the pig's skin, the clamping plate 5 abuts against the pig's leg and squeezes the pig's leg to fit the outer wall of the grille plate 301, thereby fixing the pig body and the pig's leg at the same time, thereby achieving a good fixing effect.

[0039] like Figures 1 to 9 As shown, the moving assembly 4 includes a first inclined block 401 and a second inclined block 402 fixedly connected to the grid plate 301, a limit plate 403 is movably connected inside the support frame 1, and two inclined grooves 404 facing opposite directions are provided on the surface of the limit plate 403, and a third inclined block 405 is fixedly connected to the bottom of the clamping plate 5, and the rotating assembly 7 includes a rotating drum 701 and a limit rod 704 movable inside the rotating drum 701, and a guide groove 702 is provided in an annular manner at 180 degrees on the inner wall of the rotating drum 701, and a first bevel gear 703 is fixedly connected to the top of the rotating drum 701, and a moving block 11 is fixedly connected to the bottom of the limit rod 704, and the end of the moving block 11 away from the limit rod 704 is hinged A second connecting rod 12 is connected, and a third connecting rod 13 is hinged at the bottom end of the second connecting rod 12. The end of the third connecting rod 13 away from the second connecting rod 12 is fixedly connected to the limit plate 403. A protrusion 705 is provided at a 180-degree angle on the top of the limit rod 704. The protrusion 705 is movably engaged in the guide groove 702. The transmission assembly 8 includes a first rotating shaft 801. The outside of the first rotating shaft 801 is fixedly connected with a second bevel gear 802 and a third bevel gear 803. The second bevel gear 802 and the third bevel gear 803 are oriented in opposite directions. The second bevel gear 802 is meshed with the first bevel gear 703, and the two sides of the third bevel gear 803 are respectively meshed with two bevel gear plates 9.

[0040] The above scheme is adopted: the limiting rod 704 drives the protrusion 705 to move upward under the action of external force, so that the protrusion 705 slides along the trajectory of the guide groove 702, thereby driving the rotating drum 701 and the first bevel gear 703 at its top to rotate. While the first bevel gear 703 rotates, the two bevel gear plates 9 are driven to rotate in the opposite direction through the transmission assembly 8, so that the two support plates 1001 rotate in the opposite direction, and then the two support plates 1001 respectively drive the two groups of first round rods 1002 and second round rods 1003 to rotate in the opposite direction, thereby reducing the gap in the middle of the support plate 1001. When the outer walls of the first round rod 1002 and the second round rod 1003 are in contact with the skin at the pig's neck, the support plate 1001 stops rotating, thereby limiting the pig's neck, thereby achieving a better fixing effect.

[0041] like Figure 6 , Figure 10 to Figure 11 As shown, the clamping assembly 10 includes a support plate 1001, and the outer wall of the support plate 1001 is fixedly connected to the first round rod 1002 and the second round rod 1003, one end of the first round rod 1002 and the second round rod 1003 are movably connected to the first connecting rod 1005, and the two first connecting rods 1005 are provided with straight grooves at one end close to the first round rod 1002 and the second round rod 1003, and the first connecting rod 1005 is movably connected to the second rotating shaft 1004 at one end away from the bevel gear plate 9, and the second rotating shaft 1004 is fixedly connected to the support frame 1, and the first round rod 1002 and the second round rod 1003 respectively rotate around the two second rotating shafts 1004 as the axis, and the angle between the first round rod 1002 and the second round rod 1003 is ninety degrees.

[0042] The above scheme is adopted: a straight slot is opened at one end of the first connecting rod 1005, and its function is that when the first round rod 1002 and the second round rod 1003 rotate, the ends of both close to the first connecting rod 1005 will slide inside the straight slot. The straight slot can effectively make up for the length difference between the first round rod 1002 and the second round rod 1003 after rotation, thereby ensuring the normal operation of the device.

[0043] like Figures 1 to 5 , Figure 8As shown, the top ends of the two grille plates 301 are respectively fixedly connected with the first toothed plate 302 and the second toothed plate 303, and the output shaft end of the motor 2 is fixedly connected with the gear block 304. The two sides of the gear block 304 are respectively meshed with the first toothed plate 302 and the second toothed plate 303. When the gear block 304 rotates, it drives the two grille plates 301 to move toward each other. When the grille plates 301 move, it drives the first inclined block 401 and the second inclined block 402 to move in the same direction. The first inclined block 401 The ends of the second inclined block 402 close to the limiting plate 403 are both inclined, the ends of the limiting plate 403 away from the inclined groove 404 are both inclined, the opposite ends of the two third inclined blocks 405 are both inclined, the inclined surfaces of the second inclined block 402 and the inclined surfaces of the third inclined blocks 405 abut against each other, and after the two first inclined blocks 401 move toward each other, they respectively abut against the inclined surfaces at both ends of the limiting plate 403, and after the two second inclined blocks 402 move toward each other, they squeeze the two third inclined blocks 405 to move upward.

[0044] The above scheme is adopted: the two grille plates 301 are moved toward each other, and its function is that the two grille plates 301 can adjust the distance between each other according to the size of the pig, so as to achieve effective limiting according to the size and fatness of the pig. At the same time, the two grille plates 301 move toward each other, which can apply pressure to the pig's body more evenly, thereby preventing local excessive squeezing or uneven force, thereby reducing the pig's discomfort and risk of injury.

[0045] like Figures 1 to 5 , Figure 8 As shown, the two protruding rods 6 are movably engaged in the inside of the two inclined grooves 404 respectively, and the clamping plate 5 is initially located inside the support frame 1. A plurality of slide grooves are provided on the surface of the support frame 1, and the slide grooves are used to limit the second inclined block 402, the first inclined block 401 and the third inclined block 405 when they move. A door panel is hinged on the side of the support frame 1 away from the clamping assembly 10.

[0046] The above solution is adopted: the clamping plate 5 is initially located inside the support frame 1. Its function is that when the pig enters the support frame 1, if the clamping plate 5 is located outside the support frame 1, it may block the pig's walking, affect the pig's normal movement, and bring inconvenience to subsequent operations.

[0047] The working principle and use process of the present invention are as follows: the operator opens the door panel, then drives the pig into the interior of the support frame 1, and pulls the pig head to the middle of the clamping assembly 10 through the gap opened at the top. At this time, the motor 2 is started to drive the gear block 304 to rotate, and then the first tooth plate 302 and the second tooth plate 303 drive the two grille plates 301 to move toward each other;

[0048] When the grille plate 301 moves, it drives the first inclined block 401 and the second inclined block 402 at the bottom thereof to move in the same direction, so that the second inclined block 402 abuts against the third inclined block 405, and squeezes the third inclined block 405 and the convex rod 6 at the top thereof to move upward, and then drives the clamping plate 5 to move to the outside of the bottom end of the support frame 1 through the convex rod 6, and then the grille plate 301 continues to move, so that the two first inclined blocks 401 respectively abut against the inclined surfaces at both ends of the limiting plate 403, and squeezes the limiting plate 403 to move in the direction of the transmission assembly 8, and when the limiting plate 403 moves, it drives the two convex rods 6 to slide in opposite directions along the tracks of the two inclined grooves 404, and then the convex rod 6 drives the clamping plate 5 to slide in the same direction, when the opposite sides of the two grille plates 301 respectively abut against the pig's skin, at this time, the two clamping plates 5 respectively abut against the front and rear legs on both sides of the pig, and squeeze the front and rear legs to fit with the outer wall of the grille plate 301, thereby fixing the pig's legs and body;

[0049] When the limiting plate 403 moves toward the transmission assembly 8, it drives the third connecting rod 13 to move in the same direction. Then, the third connecting rod 13 drives the moving block 11 upward through the second connecting rod 12. When the moving block 11 moves upward, the limiting rod 704 drives the protrusion 705 to slide inside the guide groove 702, so that the rotating drum 701 and the first bevel gear 703 at the top thereof rotate. When the first bevel gear 703 rotates, the first rotating shaft 801 and the third bevel gear 803 outside thereof rotate through the second bevel gear 802. When the third bevel gear 803 rotates, the two bevel gear plates 9 are driven to rotate in the opposite direction, so that the two support plates 1001 rotate in the opposite direction.

[0050] Driven by the support plate 1001, the first round rod 1002 and the second round rod 1003 close to the third connecting rod 13 rotate counterclockwise around the two second rotating shafts 1004 as the axis. While the first round rod 1002 and the second round rod 1003 rotate, they slide inside the first connecting rod 1005. The first round rod 1002 and the second round rod 1003 away from the third connecting rod 13 rotate clockwise driven by the support plate 1001. While the two groups of first round rods 1002 and second round rods 1003 rotate, the gap in the middle of the clamping assembly 10 is reduced. Subsequently, the outer walls of the first round rod 1002 and the second round rod 1003 are in contact with the skin of the pig's neck and slightly squeezed, thereby limiting the pig's neck and achieving a better fixing effect.

The fixing structure for fixing livestock according to claim 2, characterized in that: The two protruding rods (6) are respectively movably engaged in the inside of the two inclined grooves (404); the clamping plate (5) is initially located inside the support frame (1); a plurality of sliding grooves are provided on the surface of the support frame (1); the sliding grooves are used to limit the second inclined block (402), the first inclined block (401) and the third inclined block (405) when they move; a door panel is hinged on the side of the support frame (1) away from the clamping assembly (10).

10. A method for fixing livestock, applied to the fixing structure for fixing livestock according to any one of claims 1 to 9, characterized in that: The steps are as follows: S1. When the gear block (304) rotates, the two grid plates (301) are driven by the first tooth plate (302) and the second tooth plate (303) to move toward each other, thereby causing the first inclined block (401) and the second inclined block (402) at the bottom thereof to move, and then causing the second inclined block (402) to press the third inclined block (405) and the convex rod (6) at the top thereof to move upward, thereby driving the clamping plate (5) to move to the outside of the support frame (1) through the convex rod (6); S2, the first inclined block (401) then abuts against the inclined surface of the limiting plate (403), and squeezes the limiting plate (403) to move toward the transmission assembly (8), so that the two protruding rods (6) move in opposite directions along the tracks of the two inclined grooves (404), thereby driving the clamping plate (5) to move in the same direction until the clamping plate (5) abuts against the pig's leg; S3, the stopper rod (704) drives the projection (705) to slide along the track of the guide groove (702), thereby rotating the drum (701) and the first bevel gear (703), and then driving the two bevel gear plates (9) and the support plate (1001) to rotate in the opposite direction through the transmission assembly (8), and then the two support plates (1001) respectively drive the two groups of first round rods (1002) and second round rods (1003) to rotate in the opposite direction, thereby reducing the gap in the middle of the support plate (1001), until the first round rod (1002) and the second round rod (1003) are both in contact with the neck of the pig.
