[0013] Furthermore, the frame is provided with a drainage groove, and the drainage groove is connected to the side beam of the frame.

[0014] The present invention also discloses a method for opening the waterfowl based on the automatic opening device, comprising the following steps:

[0015] Step 1, the poultry carcass to be disemboweled is transferred to the front end of the automatic disembowelment device, and the poultry carcass is guided by the limiting guide rod to adjust the spatial posture; eight guide rods are arranged in a group of two in parallel, and are defined as rods 1, 2, rods 3, 4, rods 5, 6 and rods 7, 8 from the vertical direction downward; wherein, the wings and the neck are embedded between the rods 1 and 2, the trunk is embedded between the rods 3, 4 and the rods 5, 6, and the legs and the abdomen are embedded between the rods 7 and 8, and the clamping force and the spatial coercion prevent dislocation, and this is defined as the normal state;

[0016] Step 2, when the poultry carcass moves to a specific position, the trunk gives a signal through the photoelectric sensor detection, and the high-definition camera is started to take pictures to identify whether the poultry carcass is in a normal state. If it is identified as a normal state, the disembowelment device is started after a delay of 2 seconds. At this time, the poultry carcass just reaches the contact position of the profiling disembowelment tool. The second stepper motor drives the connecting rod mechanism equipped with the profiling disembowelment tool to move in a spatial arc. Then the spatial movement of the tool presents a cutting line that matches the abdominal line of the poultry carcass. The poultry carcass moves synchronously along the transmission direction. The two interact with each other to complete the disembowelment operation of the poultry carcass.

[0017] Step 3: After the opening operation is completed, the hanging chain drives the poultry carcass to leave the working area, and after the contour opening tool stops working, the water pump is started, and the disinfection nozzle starts working to disinfect the contour opening tool;

[0018] Step 4, setting the error correction function. If the high-definition camera identification in step 2 shows that the positioning is not in a normal state, the first stepper motor in the lead screw slide is started to work according to the set moving distance. After the lead screw slide drives the opening device to move this distance, the first stepper motor stops, allowing the poultry carcass to pass through the opening area, thereby avoiding the poultry carcass and not opening it. The first stepper motor is started again 2 seconds after it stops and moves in the reverse direction to reset;

[0019] Step 5, the first stepper motor is started again 2 seconds after stopping and reversed to reset, and the push rod motor is started at the same time, so that the lever is offset, so that the poultry carcass moves along the offset path to the failure zone guide rod when passing the lever, wherein the failure zone refers to the different movement paths of the opened and unopened poultry carcasses. After the push rod motor is started, it is delayed for 5 seconds to reset.
