The cooperation between the guide rail 107 and the slots 309 ensures the stability and accuracy of the neck restraint door 302 during opening and closing, preventing the neck restraint door 302 from shaking or shifting, and improving the stability and safety of the entire restraint frame.
[0032] Working principle: Place the restraint frame in a suitable position, guide the animal into the frame with its neck facing the neck yoke gate 302, then start the motor 303, which drives the worm gear 308 to rotate via the coupling. The rotation of the worm gear 308 drives the worm wheel 304 to rotate through a meshing connection. The rotation of the worm wheel 304 causes the threaded rod 305, which is fixedly connected to it, to rotate. The rotation of the threaded rod 305 causes the connecting block 301, which is threaded to it, to move along the threaded rod 305. The movement of the connecting block 301 causes the neck yoke gate 302 to open and close, thus fixing or releasing the animal's neck.
[0033] Subsequently, based on the animal's size and needs, the distance between the support rods 106 is adjusted via the adjustment unit. Motor 2 504 starts, driving threaded rod 2 506 to rotate via the coupling. The rotation of threaded rod 2 506 causes the nut 505, threadedly connected to it, to move along threaded rod 2 506. The movement of nut 505, through connecting rod 507, causes slider 503 to slide on slide rod 502. Simultaneously, support rod 106 opens and closes under the guidance of guide rod 105. The movement of support rod 106 causes the fixing unit fixed to it to move accordingly, thus achieving the fixation of the animal at different lengths.
[0034] Then, the electric push rod 601 receives a control signal and starts, its output end pushing the retaining ring 602 closer to the animal. The retaining ring 602 precisely clamps the animal according to its size and position, ensuring the animal remains stable during egg retrieval. When it is necessary to release the animal, the electric push rod 601 moves in the opposite direction, and the retaining ring 602 releases the animal.
