[0008] Further, it further includes a second limiting element. The second limiting element is connected to the frame and is used to limit the movement track of the moving element.

[0009] Further, the first limiting element includes an upper wing middle guide rod and a lower wing middle guide rod.

[0010] Further, the moving element further includes a rotating rod, the second limiting element is a vertical shaft body, the rotating rod rotates around the second limiting element as an axis, one end of the rotating rod extends into the channel, and a detection plate is fixedly connected to the other end.

[0011] Further, the resistance element includes a heavy object, a steel wire and a roller. The roller is rotatably connected to the frame. The two ends of the steel wire are respectively connected to the rotating rod and the heavy object. The steel wire contacts the roller.

Embodiment 1: like Figures 1 to 5 As shown, a residual wing detection device includes: a first limiting element 1, a moving element 2, a resistance element 3, a detection element 4 and a frame 7, wherein the first limiting element 1 is fixed relative to the frame 7, the first limiting element 1 is used to limit the displacement of the wing of the bird 9, the moving element 2 is in contact with the wing of the bird 9, the resistance element 3 is used to provide the moving element 2 with resistance to hinder the wing of the bird 9 from moving in the direction of the first limiting element 1, and the detection element 4 is used to detect the movement of the moving element 2. The first limiting element 1 enables the wing of the bird to accurately reach the area in contact with the moving element 2, so that the wing will basically not shake or deflect around the joint after being subjected to resistance, thereby improving the accuracy of detection.

[0022] Furthermore, a front-to-back through channel 10 is formed between the left and right first limiting elements 1 for the poultry 9 to move from front to back, and the moving elements 2 on the left and right sides of the channel 10 extend into the channel 10 respectively.

[0023] Further, it further includes a second limiting element 8, the second limiting element 8 is connected to the frame 7, the second limiting element 8 is used to limit the movement track of the moving element 2, and the second limiting element 8 enables the moving element 2 to reciprocate in the forward and reverse directions only under a fixed movement track, avoiding the movement of the moving element 2 in other directions from affecting the detection of its position by the detection element 4.

[0024] Further, the first limiting element 1 includes an upper-side guide rod 11 of the wing middle part and a lower-side guide rod 12 of the wing middle part. The upper-side guide rod 11 of the wing middle part and the lower-side guide rod 12 of the wing middle part. The upper-side guide rod 11 of the wing middle part is located above the lower-side guide rod 12 of the wing middle part. The upper-side guide rod 11 of the wing middle part and the lower-side guide rod 12 of the wing middle part are respectively in contact with the upper and lower sides of the joint between the wing middle part 92 and the wing root 91. The upper-side guide rod 11 of the wing middle part and the lower-side guide rod 12 of the wing middle part play a guiding and limiting role during the movement of the wing part, reducing the left-right shaking of the wing middle part 92 and the rotation of the joint with the wing root 91.

[0025] Preferably, the first limiting element 1 further includes a neck guide rod 13. Two neck guide rods 13 are located between the two lower-side guide rods 12 of the wing middle part. The neck guide rod 13 is used to limit the neck of the poultry 9. The neck of the poultry 9 extends between the two neck guide rods 13. By restricting the position of the neck, the shaking amplitude of the neck is further controlled, thereby reducing the shaking amplitude of the whole poultry 9 during movement.

[0026] Preferably, the first limiting element 1 further includes a wing tip guide plate 14. The wing tip guide plate 14 is located outside the upper-side guide rod 11 of the wing middle part and the lower-side guide rod 12 of the wing middle part. The wing tip guide plate 14 is used to limit the wing tip 93, so that the wing tip 93 can smoothly enter the included angle formed between the limiting rod 22 and the rotating rod 21 after separating from the contact with the wing tip guide plate 14.

[0027] Further, the moving element 2 further includes a rotating rod 21. The second limiting element 8 is a vertical shaft body. The rotating rod 21 rotates around the second limiting element 8. One end of the rotating rod 21 extends into the channel 10, and the other end is fixedly connected with a detection plate 23. The detection plate 23 is used to enlarge the area, making it easier for the detection element 4 to detect the position of the detection plate 23 when the detection element 4 adopts a photoelectric sensor. The detection element 4 is fixedly connected to the frame 7, and the second limiting element 8 is fixedly or rotatably connected to the frame 7. Preferably, the rotating rod 21 further includes a limiting rod 22. The limiting rod 22 is fixedly connected to the front side of the rotating rod 21. An included angle is formed between the limiting rod 22 and the rotating rod 21. The limiting rod 22 is used to limit the position of the wing tip 93, avoiding the shaking of the wing tip 93 from affecting the detection result. Preferably, it further includes a limiting column 24. The limiting column 24 is fixedly or rotatably connected to the frame 7. The limiting column 24 is used to limit the initial position of the rotating rod 21 driven by the resistance element 3.

[0028] Further, the resistance element 3 includes a heavy object 31, a steel wire 32, and a roller 34. The roller 34 is rotatably connected to the frame 7. Both ends of the steel wire 32 are respectively connected to the rotating rod 21 and the heavy object 31. The steel wire 32 contacts the roller 34. The roller 34 is used to support and guide the steel wire 32, and the roller 34 plays a role in reducing the frictional resistance. The roller 34 is rotatably connected to the frame 7. The resistance provided by the heavy object 31 to the moving element 2 is constant. Compared with the different forces generated by the spring due to different compression amounts, the force provided by the heavy object 31 is more stable, which is beneficial to making the position of the moving element 2 more accurate, thereby improving the detection accuracy.

[0029] Preferably, the resistance element 3 further includes a turntable 33. The turntable 33 is coaxial with the second limiting element 8. The moving element 2 is fixedly connected to the turntable 33. The turntable 33 rotates around the second limiting element 8 as the axis. The end of the steel wire 32 is connected to the turntable 33 (rotatably, hooked, or fixed). Preferably, the resistance element 3 further includes a cage 35. The cage 35 is connected to the heavy object 31. The cage 35 restricts the horizontal movement of the heavy object 31 to avoid the unstable resistance caused by the shaking of the heavy object 31. Preferably, the resistance element 3 further includes a mounting rod 36. The upper end of the steel wire 32 is connected to the end of the steel wire 32. The heavy object 31 is detachably connected to the mounting rod 36. By changing the number or mass of the heavy objects 31, the magnitude of the resistance is changed to adapt to the wing parts of poultry 9 with different body sizes or breeds.

[0030] Further, the detection element 4 is a photoelectric sensor or a travel switch; the detection element 4 is connected to the control device. Among them, the control device is a computer.

[0031] Preferably, the photoelectric sensor is a transmissive photoelectric sensor.

[0032] Further, it further includes a driving device 6 and a push plate 61. The driving device 6 is located below the channel 10. The push plate 61 is connected to the driving device 6. The driving device 6 drives the push plate 61 to move linearly from front to back in the channel 10. The push plate 61 contacts the shoulder of the poultry 9 to limit the position of the shoulder of the poultry 9 and reduce the shaking generated at the shoulder of the poultry 9. The driving device 6 can adopt a chain conveyor.

[0033] Further, the position of the first limiting element 1 relative to the frame 7 is adjustable, so as to adapt to the wing parts and necks of poultry 9 with different body sizes or breeds. Among them, the wing part of the poultry 9 includes a wing root 91, a wing middle 92, and a wing tip 93.

[0034] Further, the frame 7 includes a mounting plate 5, and the mounting plate 5 is used to mount the moving element 2, the resistance element 3, the detection element 4, and the second limiting element 8.

[0035] During operation, the hook moves from front to back along the conveyor line, enabling the poultry 9 to pass through the channel 10. Under the guiding structure at the front end of the first limiting element 1, the wing and neck parts of the poultry 9 enter the first limiting element 1. The wings of the poultry 9 are limited by the upper middle wing guide rod 11, the lower middle wing guide rod 12, and the wing tip guide plate 14, the neck of the poultry 9 is limited by two neck guide rods 13, and the shoulders of the poultry 9 are limited by the push plate 61. Among them, the push plate 61 moves synchronously with the hook in the channel 10.

[0036] The middle part 92 of the wing of the poultry 9 contacts the rotating rod 21.

[0037] If the bones of the middle part 92 and the root 91 of the wing are not broken, the entire wing has sufficient strength. The wing overcomes the resistance of the resistance element 3, and the wing will drive the rotating rod 21 to rotate from the initial position to the detection position. The detection element 4 detects the detection plate 23 and transmits the first signal to the control device, which is marked as a normal wing in the control device. The wing drives the rotating rod 21 to rotate away from the channel 10, and the wing disengages from the contact with the rotating rod 21 at the rotating rod 21. The rotating rod 21 is reset to contact the limiting column 24 under the drive of the gravity of the heavy object 31.

[0038] If the bones of the middle part 92 and the root 91 of the wing are broken, the strength of the entire wing is insufficient, and it cannot drive the rotating rod 21 to move or the rotating rod 21 rotates slightly but does not reach the detection position. The detection element 4 does not detect the detection plate 23 and transmits the second signal to the control device, which is marked as a defective wing in the control device. The wing is squeezed by the rotating rod 21 and generates a bending deformation at the bone fracture, so as to smoothly pass through the rotating rod 21.

[0039] Embodiment 2: As Figures 3 to 6 shown, a defective wing detection device includes: a first limiting element 1, a moving element 2, a resistance element 3, a detection element 4, and a frame 7. The first limiting element 1 is fixed relative to the frame 7. The first limiting element 1 is used to limit the displacement of the wing of the poultry 9. The moving element 2 contacts the wing of the poultry 9. The resistance element 3 is used to provide a resistance to the moving element 2 to hinder the movement of the wing of the poultry 9 along the direction of the first limiting element 1. The detection element 4 is used to detect the movement of the moving element 2. The first limiting element 1 enables the wing of the poultry to accurately reach the area in contact with the moving element 2, so that the wing basically does not shake and deflect around the joint after being subjected to resistance, thereby improving the detection accuracy.

[0040] Further, a channel 10 that runs through from front to back for the poultry 9 to move from front to back is formed between the two first limiting elements 1 on the left and right. The moving elements 2 on both sides of the channel 10 respectively extend into the channel 10. It should be noted that the legs of the poultry 9 are connected to the conveyor line of the prior art, and the conveyor line is located above the channel 10. The conveyor line hoists the poultry 9 from front to back through the channel 10.

[0041] Further, a second limiting element 8 is further included. The second limiting element 8 is fixedly connected to the frame 7. The second limiting element 8 is used to limit the movement track of the moving element 2. The second limiting element 8 enables the moving element 2 to reciprocate in the forward and reverse directions only under a fixed movement track, avoiding the movement of the moving element 2 in other directions from affecting the detection of its position by the detection element 4.

[0042] It should be noted that the moving element 2, the resistance element 3, and the second limiting element 8 in this embodiment are different from those in the first embodiment, and the rest of the principles are the same as those in the first embodiment.

[0043] Further, the second limiting element 8 is a cylinder. The moving element 2 is slidably connected to the second limiting element 8. The second limiting element 8 is fixedly connected to the frame 7. Both ends of the resistance element 3 are in contact with the moving element 2 and the second limiting element 8 respectively. The resistance element 3 has elasticity.

[0044] Further, the detection element 4 is located inside the second limiting element 8 and is fixedly connected to the second limiting element 8. Preferably, the detection element 4 is a photoelectric sensor or a travel switch.

[0045] Further, the resistance element 3 is a spring.

[0046] Further, a guiding inclined surface 201 is formed on the front side of the moving element 2.

[0047] During operation, the hook moves from front to back along the conveyor line, enabling the poultry 9 to pass through the channel 10. Under the guiding structure at the front end of the first limiting element 1, the wing and neck parts of the poultry 9 enter the first limiting element 1. The wings of the poultry 9 are limited by the upper wing guide rod 11, the lower wing guide rod 12, and the wing tip guide plate 14 in the middle of the wing, the neck of the poultry 9 is limited by the two neck guide rods 13, and the shoulders of the poultry 9 are limited by the push plate 61. Among them, the push plate 61 moves synchronously with the hook in the channel 10.

[0048] The middle part 92 of the wing of the poultry 9 contacts the guiding inclined surface 201 of the moving element 2. The force received by the guiding inclined surface 201 is divided into two components in the front - back and left - right directions. The component force in the left - right direction will drive the moving element 2 to move.

[0049] If the bones of the middle part 92 and the root part 91 of the wing are not broken, the entire wing has sufficient strength. The wing overcomes the resistance of the resistance element 3, squeezes the driving movement element 2 from the initial position to the detection position. The detection element 4 detects that the movement element 2 reaches the detection position and transmits a first signal to the control device, which marks it as a normal wing in the control device. The wing drives the movement element 2 to leave the channel 10. After the poultry passes between the two movement elements 2, it disengages from the contact with the movement element 2. The movement element 2 is driven by the elastic force of the resistance element 3 and resets to the initial position.

[0050] If the bones of the middle part 92 and the root part 91 of the wing are broken, the strength of the entire wing is insufficient, and it cannot drive the movement element 2 to move or the movement element 2 slides slightly but does not reach the detection position. The detection element 4 does not detect that the movement element 2 reaches the detection position and transmits a second signal to the control device, which marks it as a defective wing in the control device. The wing is squeezed by the movement element 2 and generates a bending deformation at the bone fracture, so as to smoothly pass through the movement element 2.

[0051] Embodiment 3: A detection and processing method using the defective wing detection device as described in Embodiment 1 or 2 includes the following steps: Step S1: The poultry 9 enters between the two first limiting elements 1 from the front end. The first limiting elements 1 limit the poultry 9 so that the poultry 9 moves from front to back along the first limiting elements 1. Step S2: The wing of the poultry 9 contacts the movement element 2 at the initial position. When the bones of the root part 91 and the middle part 92 are not broken, the middle part 92 of the wing drives the movement element 2 to overcome the resistance of the resistance element 3, so that the movement element 2 moves to the detection position. When the bones of the root part 91 and the middle part 92 are broken, the movement element 2 driven by the middle part 92 of the wing cannot completely overcome the resistance of the resistance element 3, so that the movement element 2 cannot move to the detection position. Step S3: The detection element 4 detects whether the movement element 2 moves to the detection position. When the movement element 2 is detected, it transmits a first signal to the control device. When the movement element 2 is not detected, it transmits a second signal to the control device, and then the control device transmits a signal to the detachment device or the marking device. Step S4: The poultry 9 disengages from the contact with the movement element 2, and the movement element 2 returns to or remains in the initial position. Step S5: The detachment device or the marking device processes the poultry 9 corresponding to the second signal.

[0052] When using the detachment device, when the conveying line transports to the designated position (after leaving the detection device), the detachment device drives the poultry 9 marked as a defective wing to fall off the hook.

[0053] When using a marking device, when the marking device is transported to a designated position (after leaving the detection device) on the conveyor line, it physically marks the poultry 9 marked as having a defective wing. After that, the poultry 9 marked as having a defective wing is removed from the hook manually or mechanically.

[0054] Thus, it is possible to avoid mixing the poultry 9 with normal wings and the poultry 9 with defective wings.

[0055] The present invention has been described by way of example above, but the present invention is not limited to the above specific embodiments, and any modification or variation based on the present invention falls within the scope of protection required by the present invention.
