Description

Technical Field

[0001] This invention belongs to the technical field of poultry processing equipment, and particularly relates to an automatic evisceration device and method for waterfowl. Background Technology

[0002] Currently, most poultry products entering the market are cut-up, and they have become the second largest source of meat for residents. Global waterfowl farming and processing are mainly concentrated in China. Although a small number of foreign companies have fully automated cutting production lines, the equipment is very expensive and is mostly poultry slaughtering equipment. Moreover, the scale of domestic slaughtering enterprises varies, making it not universally applicable. Therefore, most domestic slaughtering and cutting lines adopt a semi-automatic and semi-manual approach. For the evisceration part, manual cutting with a knife or scissors is used. One production line requires 2-3 people, and larger-scale ones require more. This is not only physically demanding, but also results in uneven evisceration openings.

[0003] To address the problems existing in the above-mentioned waterfowl slaughtering and processing process, and based on the factory slaughtering model, the present invention aims to design and invent an automatic waterfowl gutting device. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to provide an automatic evisceration device and method for waterfowl that reduces the labor intensity of workers, is simple in structure and manufacturing, operates smoothly, has a good evisceration effect, is inexpensive, and is highly adaptable.

[0005] Technical Solution: The present invention provides an automatic evisceration device for waterfowl, comprising a frame and a chain. A plurality of limiting guide rod connecting plates are respectively installed on the top of the frame, and limiting guide rods are installed through these connecting plates. A photoelectric sensor is installed on one of the limiting guide rod connecting plates. A lever mechanism is installed on the frame on the same side as the photoelectric sensor. A high-definition camera, a control cabinet, and a drainage trough are respectively installed on the sides of the frame. A lead screw slide is installed in the middle of the frame, and a first stepper motor and an evisceration device are installed on the lead screw slide. A disinfection tank is installed at the bottom of the frame, and the disinfection tank is connected to the evisceration device through a disinfection device. The control cabinet is communicatively connected to a computer.

[0006] Furthermore, the frame is made of aluminum profile, and the number of limiting guide rod connecting plates is 33.

[0007] Furthermore, the lever mechanism includes a lever, a push rod, and a push rod motor connected in sequence; the lever is provided with an M4 bolt, and the other end of the push rod motor is provided with a push rod motor support; the lever mechanism is connected to the frame through the push rod motor support.

[0008] Furthermore, the limiting guide rod includes eight guide rods, each of which is equipped with two M14 threaded rods. The M14 threaded rods are connected to the guide rods via a tee connector, and the other end of the M14 threaded rod is connected to the limiting guide rod connecting plate to fix it to the frame.

[0009] Furthermore, the flaring device includes a protective outer shell, a linkage mechanism, and a protective cover; the disinfection device includes a water pump, a spray head, a spray head support base, a water outlet pipe, and a water suction pipe; one end of the water suction pipe is connected to a disinfection water tank, and the other end is connected to the water pump; one end of the water outlet pipe is connected to the water pump, and the other end is connected to the spray head; the spray head is mounted on the protective cover via the spray head support base; and the water pump is installed inside the protective outer shell.

[0010] Furthermore, the linkage mechanism includes a linkage mechanism support base, on the back of which a second stepper motor is mounted via M3 bolts, and on the front of which a rocker support base and a crank are mounted; the rocker support base is connected to a rocker via a rocker fixing component, the crank is connected to a connecting rod, the rocker and the connecting rod are connected, and a contour cutting tool is provided at the connection point.

[0011] Furthermore, the guide rod is made of stainless steel tubing with a diameter of 16mm and a wall thickness of 1.5mm.

[0012] Furthermore, the lead screw slide is equipped with a first stepper motor, which drives the lead screw slide to move.

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

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

[0015] Step 1: The poultry carcass to be gutted is transferred to the front end of the automatic gutting device. The carcass is guided by the limiting guide rods to adjust its spatial posture. The eight guide rods are arranged in pairs, and from vertical to bottom, they are defined as rods 1, 2, 3, 4, 5, 6 and 7, 8. Among them, the wings and neck are embedded between rods 1 and 2, the torso is embedded between rods 3, 4 and 5, 6, and the legs and abdomen are embedded between rods 7 and 8. The clamping force and spatial stress prevent dislocation, and this is defined as the normal state.

[0016] Step 2: When the poultry carcass moves to a specific position, the torso is detected by a photoelectric sensor and a signal is given. The high-definition camera is activated to take a picture and identify whether the poultry carcass is in a normal state. If it is identified as being in a normal state, the evisceration device is activated after a 2-second delay. At this time, the poultry carcass just reaches the contact position of the contour evisceration cutter. The second stepper motor drives the linkage mechanism with the contour evisceration cutter to perform a spatial arc movement. Then the cutter moves in space to present 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 and thus complete the evisceration operation of the poultry carcass.

[0017] Step 3: After the evisceration operation is completed, the chain will carry the poultry carcass away from the work area. After the evisceration cutter stops working, the water pump will be started and the disinfection nozzle will start working to disinfect the evisceration cutter.

[0018] Step 4: Set the error correction function. If the high-definition camera in Step 2 detects that the positioning is not normal, start the first stepper motor in the lead screw slide and work according to the set moving distance. The lead screw slide drives the evisceration device to move this distance and then the first stepper motor stops, allowing the poultry carcass to pass through the evisceration area, thereby avoiding the poultry carcass and not performing evisceration. After the first stepper motor stops, it restarts 2 seconds later and reverses to move and reset.

[0019] Step 5: After the first stepper motor stops, restart it 2 seconds later and reverse the movement to reset. At the same time, start the push rod motor to deflect the lever, so that the poultry carcass moves along the deflected path to the guide rod in the failure zone when passing the lever. The failure zone refers to the different movement paths of the eviscerated and unceviscerated poultry carcasses. After the push rod motor starts, it resets after a 5-second delay.

[0020] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages:

[0021] This invention provides an automatic evisceration device for waterfowl processing, which can automatically eviscerate carcasses, reduce labor intensity, save enterprise expenses, and improve product qualification rate. The device is simple in structure and manufacturing, easy to operate, and operates smoothly. It can be adjusted according to body size specifications and different batches of carcasses, improving its applicability. It also prevents accidental cutting of the neck, wings, and legs of the carcass during evisceration. The device prevents the carcass from tipping over or shifting during movement, resulting in good evisceration effect. It prevents splashing of internal organs after evisceration and protects the internal organs, ensuring continuous operation. The device also includes an error correction function and a disinfection device. Carcasses that fail to be positioned or exhibit positioning failures are removed and guided to manual processing to prevent damage to the carcass. The device also disinfects the cutting tools to prevent bacterial growth. Attached Figure Description

[0044] Step 1: The poultry carcass to be gutted is transferred to the front end of the automatic gutting device. The carcass is guided by the limiting guide rods to adjust its spatial posture. The eight guide rods are arranged in pairs, and from vertical to bottom, they are defined as rods 1, 2, 3, 4, 5, 6 and 7, 8. Among them, the wings and neck are embedded between rods 1 and 2, the torso is embedded between rods 3, 4 and 5, 6, and the legs and abdomen are embedded between rods 7 and 8.
