Description

Technical Field

[0001] This invention belongs to the technical field of live chicken slaughtering production lines, and specifically relates to an automatic chicken hanging device. Background Technology

[0002] In the live chicken slaughtering production line, the live chickens in the cages need to be grabbed in advance and their legs are hung on hooks (usually by the operator reaching into the cage to grab the legs of the live chickens and then hanging them on hooks) so that subsequent bleeding and defecation operations can be carried out.

[0003] Currently, the main method of suspending live chickens involves manually hanging them on hooks or suspension devices, such as slaughter line hanging devices (CN220987453U), chicken hanging systems (CN207011612U), and hanging devices for chicken slaughter lines (CN209749627U). However, its disadvantages include: requiring a large amount of labor, low efficiency in hanging chickens, and inconvenience in operation. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic chicken-hanging device that can at least solve the problems mentioned in the background art.

[0005] The present invention adopts the following technical solution.

[0006] An automatic chicken-hanging device includes a transmission system, a suspended track system above the transmission system, and a chicken-grabbing system on the transmission system. The chicken-grabbing system is used to hold the legs of a standing live chicken and hang the live chicken upside down on the hooks of the suspended track system.

[0007] Furthermore, the chicken-catching system includes a bucket-shaped container with an open top that is basically flush with the top surface of the transmission system. The bottom of the bucket-shaped container is also open and located directly above the limiting mechanism. The limiting mechanism is only used to hold the body of the live chicken, with the legs of the live chicken exposed below the limiting mechanism.

[0008] Furthermore, the chicken-catching system also includes a horizontally arranged fork assembly, which includes several integrally formed U-shaped rods. Hooks are provided on the U-shaped rods, and gate-shaped rods are provided on the inner side of the U-shaped rods. The open space formed by the gate-shaped rods and the U-shaped rods is used to hold the legs of the live chicken, and the open space has a structure that is wider at the top and narrower at the bottom.

[0009] Furthermore, the minimum width of the open space is approximately equal to the diameter of a live chicken's lower leg.

[0010] Furthermore, a baffle is provided below the limiting mechanism, and the baffle is connected to a vertically arranged second cylinder. The distance between the baffle and the limiting mechanism allows the fork assembly to pass laterally. This structure facilitates a more stable and smoother fork hold of the live chicken leg.

[0011] Furthermore, the limiting mechanism includes two spaced and parallel channel steels, with several spaced and vertically arranged rollers on the inner side of the channel steels. The width between the two channel steels is just enough to hold the body of a single live chicken. This design allows for more successful holding of the live chicken's body and facilitates adjustment of the chicken's position.

[0012] Furthermore, a third cylinder is connected to the top of the channel steel A, which is far from the first cylinder. The third cylinder is installed on the outer wall of the bucket-shaped container and is used to control the channel steel A to rise and fall at a set time.

[0013] Furthermore, a first cylinder arranged laterally is connected to a U-shaped rod located on the back side of the hook body. The first cylinder is used to control the lateral movement of the fork assembly.

[0014] To enable more efficient hanging of chickens, a row of rollers is installed on each of the two opposite walls of the top of the bucket-shaped container. These rollers serve as part of the transmission system and support the chicken cage, with a hollow space between the two rows of rollers.

[0015] Furthermore, the power system of the suspended track system, the power system of the transmission system, and the first, second, and third cylinders are all connected to a controller. When the controller's processor executes its program, it performs the following functions:

[0016] Step 01: When the chicken cage moves onto the bucket-shaped container with the conveyor system, control the conveyor system to pause;

[0017] Step 02: After the live chicken in the cage falls between the two channel steels, control the first cylinder to move the fork assembly laterally. During this process, the fork assembly holds the legs of the live chicken.

[0018] Step 03: After the hook of the fork assembly is hooked onto the hook, control the second cylinder to move the baffle downward.

[0019] Step 04: After the fork assembly is moved away with the hook, control the second cylinder to reset the baffle, and control the first cylinder to reset.

[0020] Beneficial effects: The solution of this invention can not only successfully suspend at least ten live chickens on the suspension track system at one time, significantly improving the efficiency of live chicken suspension, but also greatly simplify the difficulty of live chicken suspension operation, eliminating the key operation step of directly grabbing chickens from the chicken cage or holding the chicken legs, which can make the live chicken suspension more successful, while saving a lot of manpower and labor costs.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0028] Combination Figures 1 to 6 As shown, an automatic chicken-hanging device includes a transmission system 1, a suspended track system above the transmission system 1, and a chicken-grabbing system on the transmission system 1. The chicken-grabbing system is used to hold the legs 8 of a standing live chicken and hang the live chicken upside down on the hooks 2 of the suspended track system.

[0029] In this embodiment, the chicken-catching system includes a funnel-shaped container 3. The height of the chamber 20 of the funnel-shaped container 3 is 30cm (the maximum height is no more than 35cm). The top of the funnel-shaped container 3 is open and basically flush with the top surface of the transmission system 1. The bottom of the funnel-shaped container 3 is also open and located directly above the limiting mechanism. The limiting mechanism is only used to hold the body 7 of the live chicken, and the legs 8 of the live chicken are exposed below the limiting mechanism. A row of rollers 19 is provided on the two opposite walls of the top wall of the funnel-shaped container 3. The rollers 19 are part of the transmission system and are used to support the chicken cage 6. There is a hollow space between the two rows of rollers 19. The chicken-catching system also includes a horizontally arranged fork assembly 10. The fork assembly 10 includes several integrally formed U-shaped rods 9. Hooks 11 are provided on the U-shaped rods 9. A gate-shaped rod 13 is provided on the inner side of the U-shaped rods 9. The open space 14 formed by the gate-shaped rod 13 and the U-shaped rods 9 is used to hold the legs 8 of the live chicken. The open space 14 has a structure that is wider at the top and narrower at the bottom. The minimum width of the open space 14 is basically equal to the diameter of the lower leg of the live chicken. A horizontally arranged first cylinder 12 is connected to the U-shaped rod 9 located on the back side of the hook 11. The first cylinder 12 is used to control the horizontal movement of the fork assembly 10.

[0030] In this embodiment, a baffle 4 is provided below the limiting mechanism. The baffle 4 is connected to a vertically arranged second cylinder 5. The distance between the baffle 4 and the limiting mechanism allows the fork assembly 10 to pass laterally. The limiting mechanism includes two spaced and parallel channel steels 15. Several spaced-apart brush rollers 16 are provided on the inner side of the channel steels 15. The brush rollers 16 are arranged vertically. The rotation of all brush rollers 16 is connected to a motor through a gear transmission mechanism. The width between the two channel steels 15 is just enough to hold the body 7 of a single live chicken. The function of the brush rollers 16 is to adjust the position of the live chicken. The brush rollers 16 during the rotation process can guide the live chicken that has not fallen into place to adjust laterally and vertically into place. The top of the channel steel A18 away from the first cylinder 12 is connected to a third cylinder 17. The third cylinder 17 is installed on the outer wall of the bucket-shaped container 3. The third cylinder 17 is used to control the channel steel A18 to rise and fall at a set time.

[0031] In this embodiment, the power system of the suspended track system, the power system of the transmission system 1, the motor of the roller 16, and the first cylinder 12, the second cylinder 5, and the third cylinder 17 are all connected to the controller. When the processor of the controller executes its program, it performs the following functions:

[0032] Step 01: When the chicken cage 6 moves onto the bucket-shaped container 3 along with the conveying system 1, the conveying system 1 is paused, and the motor of the hair roller 16 is controlled to run at the set speed.

[0033] Step 02: After the live chicken in the chicken cage 6 falls between the two channel steels 15, control the first cylinder 12 to move the fork assembly 10 laterally. During this process, the fork assembly 10 forks the legs 8 of the live chicken.

[0034] Step 03: After the hook 11 of the fork assembly 10 is hooked onto the hook 2, the second cylinder 5 is controlled to move the baffle 4 downward.

[0035] Step 04: After the fork assembly 10 is moved away with the hook 2, the second cylinder 5 is controlled to reset the baffle 4, and the first cylinder 12 is controlled to reset.

[0036] In this embodiment, the chicken-hanging device operates as follows: When live chickens are ready to leave the farm, they are placed into chicken cages 6. The chicken cages 6 containing the live chickens are then placed on the conveyor system 1, with the door frame / door panel of the chicken cages 6 against the top surface of the conveyor system 1. When the chicken cages 6 containing the live chickens move along the conveyor system 1 onto the bucket-shaped container 3, the conveyor system 1 is paused. The state at this time can be referred to... Figure 1As shown; next, open the door frame (pull-out door frame) on the chicken coop 6. At this time, the live chicken in the chicken coop 6 will quickly fall into the chamber 20 of the bucket-shaped container 3, and then fall down along the chamber 20 between the two channel steels 15. Since the live chicken is standing in the chicken coop 6 and the height of the chamber 20 is small, the live chicken falls between the two channel steels 15 instantly. In most cases, the live chicken can still be in a "standing" posture when it falls between the two channel steels 15. Since the width between the two channel steels 15 is just enough to hold the body 7 of a single live chicken, the legs 8 of the live chicken will be exposed below the limiting mechanism. Next, control the first cylinder 12 to move the fork assembly 10 laterally, so that the fork assembly 10 will hold the live chicken's legs 8 (in the initial state, the fork assembly 10 is away from the channel steel 15). During this process, when the fork assembly 10 just contacts the live chicken's legs 8, the live chicken's legs 8 will be subjected to lateral force (first cylinder 12) The chicken deflects under the force generated by the action, but stops deflecting when the chicken leg 8 is blocked by the baffle 4. At this time, as the telescopic rod of the first cylinder 12 continues to move forward, the chicken leg 8 will be smoothly inserted into the open space 14. Then, as the suspended track system operates, when the hook 2 of the suspended track system touches the hook body 11, the hook body 11 of the fork assembly 10 will hook onto the hook 2. Then, the second cylinder 5 is activated to move the baffle 4 down, and the fork assembly 10 will change from a horizontal state to a vertical state under its own gravity. At this time, the live chicken and the hook body 11 are upside down on the hook 2. Then, after the fork assembly 10 moves away with the hook 2, the second cylinder 5 is activated again to reset the baffle 4, and the first cylinder 12 is reset again. Then, the transmission system 1 is activated to move forward one stroke, and the next chicken cage 6 containing a live chicken is moved along the transmission system 1 to the bucket-shaped container 3, and then the process of suspending the live chicken continues as described above.

[0037] In this embodiment, the hook 2 is a ring with a rod or connecting rope, and the hook body 11 is an open hook body. When the hook body 11 extends to the target position with the extension of the first cylinder 12, the hook body 11 is located at the necessary passage position of the ring on the hook 2, such as... Figure 5 As shown, the hook 11 is located on the moving trajectory of the ring, which ensures that the hook 11 is hooked on the hook 2.

[0038] In this embodiment, when the fork assembly 10 is in a horizontal state and the baffle 4 is in the initial state, the distance between the fork assembly 10 and the top edge of the baffle 4 is set to 3-5mm. This not only helps to smoothly insert the chicken leg 8 into the open space 14 of the fork assembly 10, but also helps the hook 11 of the fork assembly 10 to hang more accurately on the hook 2.

[0039] In this embodiment, one of the key points is that by directly utilizing the aforementioned specific structure, multiple live chickens in the chicken coop 6 can be simultaneously lowered into a short-elevation space and secured between two channel steels 15. Then, with the help of the horizontally arranged fork components 10, they can be simultaneously secured to the legs 8 of the live chickens. This allows at least ten live chickens to be successfully suspended on the suspension track system at once, and it only takes about twenty seconds to suspend twelve live chickens on the suspension track system at once (while the traditional manual suspension method takes at least one minute). This significantly improves the efficiency of live chicken suspension and greatly simplifies the operation of live chicken suspension, eliminating the key step of directly grabbing chickens from the chicken coop or clamping their legs. This allows for smoother live chicken suspension and saves a lot of manpower and labor costs. During use, the number of live chickens in the chicken coop 6 can be configured according to the number suitable for the open space 14, which facilitates the full opening of the door frame on the chicken coop 6 at once. When there are many live chickens in the chicken coop 6, only the door frame on the chicken coop 6 needs to be partially opened, allowing the live chickens in the chicken coop 6 to fall in multiple times.
