The wing is pressed by the rotating rod 21 to produce bending deformation at the broken bone, so as to smoothly pass through the rotating rod 21.

[0049] Embodiment two:

[0050] As shown in Figure 6 A bird wing detection mechanism, comprising: a movement element 2, a resistance element 3 and a detection element 4, the resistance element 3 is connected with the movement element 2, the resistance element 3 is used for providing resistance to the movement element 2, the movement element 2 moves relative to the detection element 4, and the detection element 4 is used for detecting the movement of the movement element 2.

[0051] Further, it further comprises a mounting frame 5 and a second limiting element 8, the movement element 2 is movably connected with the mounting frame 5 through the second limiting element 8, the second limiting element 8 is used for limiting the movement track of the movement element 2, and the detection element 4 is fixedly connected with the mounting frame 5. The second limiting element 8 makes the movement element 2 only move in the fixed movement track in the positive and negative directions, avoiding the movement element 2 to produce other direction movement to affect the detection of the position of the detection element 4.

[0052] Further, the second limiting element 8 is a cylinder, the movement element 2 is slidably connected with the second limiting element 8, the second limiting element 8 is fixedly connected with the rack 7, the resistance element 3 is in contact with the movement element 2 and the second limiting element 8 at both ends, and the resistance element 3 has elasticity.

[0053] Furthermore, 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 limit switch.

[0054] Furthermore, the resistance element 3 is a spring.

[0055] Furthermore, the motion element 2 has a guide slope 201 formed on its front side.

[0056] During operation, the bird 9 moves in a straight line from front to back, with the wing-destroying detection mechanism located on the side of the wing furthest from the body. As the bird 9 moves, it passes the wing-destroying detection mechanism, and the wing midpiece 92 of the bird 9 comes into contact with the guide ramp 201 of the motion element 2. The force on the guide ramp 201 is divided into two components: forward and backward, and left and right. The left and right component drives the motion element 2 to slide.

[0057] If the bones of the wing midpiece 92 and wing root 91 are not broken, the entire wing has sufficient strength to overcome the resistance of the resistance element 3, pushing the drive motion element 2 from the initial position to the detection position. The detection element 4 detects that the motion element 2 has reached the detection position and transmits a first signal to the control device, which marks it as a normal wing. The wing drives the motion element 2 away from the channel 10, and the bird, after passing between the two motion elements 2, disengages from the motion elements 2. Under the elastic force of the resistance element 3, the motion element 2 returns to its initial position.

[0058] If the bones in the wing midpiece 92 and wing root 91 of the wing are fractured, the overall strength of the wing is insufficient to drive the motion element 2, or the motion element 2 slides slightly but does not reach the detection position. The detection element 4 does not detect the motion element 2 reaching the detection position and transmits a second signal to the control device, which marks it as a damaged wing. The wing, compressed by the motion element 2, bends and deforms at the fractured bone, thus allowing it to pass smoothly through the motion element 2.

[0064] Preferably, the first limiting element 1 further comprises a wing tip guiding plate 14, the wing tip guiding plate 14 is located outside the middle wing upper side guide rod 11 and the middle wing lower side guide rod 12, and the wing tip guiding plate 14 is used for limiting 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 being separated from the wing tip guiding plate 14.

[0065] Further, the drive device 6 and the push plate 61 are further included, the drive device 6 is located below the passage 10, the push plate 61 is connected with the drive device 6, the drive device 6 drives the push plate 61 to move linearly in the passage 10 from front to back, and the push plate 61 is in contact with the shoulder of the poultry 9 and is used for limiting the position of the shoulder of the poultry 9. The push plate 61 is in contact with the shoulder of the poultry 9 and is used for limiting the position of the shoulder of the poultry 9, and reducing the shaking generated at the shoulder of the poultry 9. The drive device 6 can adopt a chain conveyor.

[0066] Among them, the wing of the poultry 9 comprises a wing root 91, a middle wing 92 and a wing tip 93.

[0067] When working, the hook moves along the conveying line from front to back, so that the poultry 9 passes through the passage 10. Under the guide structure at the front end of the first limiting element 1, the two wing parts and the neck part of the poultry 9 enter the first limiting element 1.

The push plate 61 moves synchronously with the hook in the passage 10.

[0068] The two wing parts of the poultry 9 correspond to the first limiting element 1 and the residual wing detection mechanism respectively, and each wing part is detected by a separate residual wing detection mechanism.

[0069] After the poultry 9 leaves the first limiting element 1, the disengaging device or the marking device receiving the signal of the control device processes the poultry 9 corresponding to the second signal.

[0070] When the disengaging device is used, the disengaging device drives the poultry 9 marked as residual wing to fall off from the hook when the conveying line is transported to the specified position (after leaving the detection device).

[0071] When the marking device is used, the marking device makes physical marking on the poultry 9 marked as residual wing when the conveying line is transported to the specified position (after leaving the detection device). Then, the poultry 9 marked as residual wing is manually or mechanically taken off from the hook.

[0072] Therefore, the poultry 9 with normal wing parts and the poultry 9 with residual wing are prevented from being mixed together.
