[0022] Working principle: The integrated fish-killing and washing equipment provided by this invention includes the following operating steps in practical applications:

[0023] Step 1, live fish delivery: First, the operator or an external conveyor places the live fish into the upper part of the support frame. Under the rolling action of the conveyor rollers, the live fish slide between the two guide plates. Then, the first bidirectional linear module is activated, causing the two moving rods to separate the guide plates, allowing live fish of different sizes to slide smoothly through the channel between the two guide plates into the upper part of the first conveyor. This completes the first step.

[0024] Step 2, Stunning and Cutting the Live Fish: When the live fish falls onto the upper part of the first conveyor, the first electric push rod in the stunning and cutting mechanism is activated, causing the rod to drive the angle plate downwards, pressing the live fish longitudinally. The first motor is then activated to drive the worm gear to rotate, which in turn drives the worm wheel to rotate the live fish 90 degrees, changing its posture to a horizontal position. Then, the second bidirectional linear module is activated, and the distance between the two moving blocks is adjusted to accommodate the length of the fish. After that, the two cylinders are activated, which drive the hammers to strike the fish's head several times to achieve the stunning effect. The use of two hammers on the left and right sides ensures that the fish's head is struck from different orientations, improving the tolerance for strikes. After the fish is stunned, the first motor is activated again, causing the worm gear to drive the worm wheel to rotate, so that the fish's belly faces the first electric slide rail. Then, the cutting machine is activated, and the first electric slide rail drives the cutting machine to move and cut open the fish's belly. At this point, the stunning and cutting of the live fish is complete.

[0025] Step 3: Cleaning the fish scales and belly: After the fish belly is cut open, the first conveyor is activated to send the fish to the scale and belly processing mechanism. Activating the third motor inside this mechanism rotates the third electric slide rail. This operation adjusts the distance between the two electric grippers to fit the fish's length. The two grippers then lift the fish from the head and tail. The third motor then rotates the third electric slide rail, raising the fish. Multiple high-pressure rotating nozzles on the semi-circular tube then spray high-pressure water into the gaps in the fish scales and the cut belly. During this process, adjusting the position of the semi-circular tube and using the second motor to change the rotation position of the linear module allows for multi-angle spraying of the fish. The process involves flushing out the fish scales and internal organs, which then fall into a receiving tray. Two side baffles are installed to prevent water and the flushed fish scales and internal organs from splashing. Guided by the side baffles, the fish falls into the receiving tray. During this process, the linear module is controlled to move the semi-circular tube linearly. The water source for the semi-circular tube is supplied by external equipment. After cleaning the fish scales and belly, the third motor is restarted to change the rotation position of the third electric slide rail. At the same time, the rotation of the gear drives the rack to move the receiving tray synchronously. When the electric gripper picks up the fish and sends it to the second conveyor, the receiving tray moves forward to make room. When the electric gripper rotates, it moves backward to return to its original position. When the fish is conveyed to the top of the second conveyor, the cleaning of the fish scales and belly is completed.

[0026] Step 4: Equal-distance segmentation of the fish body: After the fish is conveyed to the anvil by the second conveyor, the variable-distance module in the variable-distance fish-cutting mechanism is activated. The spacing between the cutting blades can be adjusted according to the processing needs of the fish product. Once the segmentation spacing is confirmed, the hydraulic rod is activated, causing the entire variable-distance module to move downwards. As the variable-distance module moves downwards, the pulleys at the bottom of the inclined pressure rods on both sides will first contact the surface of the anvil and expand to both sides. The elastic pressure lines between the front and rear inclined pressure rods on both sides will press against the fish body, achieving a soft fixation effect and pre-fixing the fish body. Then, the hydraulic... As the pressure bar continues to press down, it will drive the variable pitch module and the multiple fish-cutting knives installed below it to cut the fish into sections. After the sections are cut, the hydraulic rod retracts, and the inclined pressure bars on both sides will also return to their original positions under the action of the damping spring shaft, ready for the next auxiliary fixing operation. After the fish is cut into sections, the second electric push rod is activated to move the push plate, which will send the cut fish sections on the anvil onto the U-shaped conveyor and transport them to the cleaning tray. If the fish does not need to be cut into sections, the second conveyor can be activated to reverse the transport, and the fish will fall directly into the cleaning tray for subsequent cleaning operations.

[0027] During the fish-cutting process, by activating multiple exhaust fans and suction boxes in the gas extraction mechanism, some of the fishy smell can be extracted, helping to reduce the fishy odor in the equipment operation area.

[0028] Step 5, Rotation Cleaning: After the cut fish pieces are put into the cleaning pan, clean water is injected into the cleaning pan through the external water injection device. Then, the fourth motor is started to drive the stirring blades to clean the fish pieces inside the cleaning pan. After cleaning is completed or after the equipment is stopped for maintenance, the water inside the cleaning pan and the water receiving pan can be drained at the same time by opening the solenoid valve connecting the drain pipe to the cleaning pan and the water receiving pan.

[0029] The integrated fish-killing and washing equipment provided by this invention has a high degree of integration and can perform processes such as stunning, side cutting, cleaning fish scales and belly, and cutting into sections on fresh live fish. The fish body is well processed and the fish meat is intact. It is suitable for continuous operation and production in fish meat processing plants.

[0030] This invention provides an integrated fish-killing and washing processing device. It has the following beneficial effects:

[0031] 1. This invention, through the coordinated operation of multiple functional mechanisms, can perform processes such as stunning, lateral cutting, cleaning of scales and entrails, and segmentation on fresh live fish. The fish body is well processed, and the fish meat remains intact. It is suitable for continuous production in fish processing plants, effectively reducing the labor intensity of operators and improving the production efficiency of fish products.

[0032] 2. This invention features a fish-body equidistant segmentation process. After the fish is conveyed to the anvil by the second conveyor, the variable-distance module in the variable-distance fish-cutting mechanism is activated. The spacing between the fish-cutting blades can be adjusted according to the processing needs of the fish product. By activating the hydraulic rod, the entire variable-distance module can be moved downwards, while the elastic pressure line between the front and rear inclined pressure rods on both sides presses on the fish body, achieving a soft fixation effect and pre-fixing the fish body. As the hydraulic rod continues to press down, it will drive the variable-distance module and the multiple fish-cutting blades installed below it to segment the fish body. The segmentation effect is good and can be adjusted according to actual needs.

[0033] 3. This invention features a fish scale and belly treatment mechanism. Two electric grippers lift the fish from its head and tail. Once lifted, multiple high-pressure rotating nozzles on a semi-circular tube are activated, spraying high-pressure water into the gaps in the fish scales and the cuts in the belly. During this process, by adjusting the position of the semi-circular tube and changing the rotation position of the linear module via a second motor, multi-angle spraying can be achieved, flushing out the scales and internal organs from the belly. Guided by the side baffles, the water falls into the receiving tray. By controlling the operation of the linear module, the semi-circular tube can move linearly, achieving multi-angle cleaning of the fish body with good cleaning effect and wide range.

[0034] 4. This invention, by setting up a stunning and side-cutting mechanism, uses a folding plate to press the live fish longitudinally. A first motor drives a worm gear to rotate, which in turn drives a worm wheel to rotate the live fish 90 degrees, changing its position to a horizontal one. Then, by activating two cylinders, a hammer is driven to strike the fish's head several times, achieving a stunning effect. Once the fish is stunned, its belly faces the first electric slide rail. The cutting machine is then activated, and the first electric slide rail moves the cutting machine to cut open the fish's belly. This completes the stunning and cutting process of the live fish, improving upon the high manual labor intensity of traditional fish-killing methods. Attached Figure Description

The first bidirectional linear module 403 includes two moving rods 404 threadedly connected to the module bidirectional screw. Guide clamps 405 are fixedly connected to the bottom end of each of the two moving rods 404.

[0055] Specifically, in actual operation, the operator or an external conveyor first places the live fish into the upper part of the support frame 401. Under the rolling action of the conveyor roller 402, the live fish slide between the two guide clamps 405. Then, the first bidirectional linear module 403 is activated, causing the two moving rods 404 to drive the guide clamps 405 to separate, so that live fish of different sizes can smoothly slide through the channel between the two guide clamps 405 into the upper part of the first conveyor 5, thus completing the feeding of the fish.

[0056] For further details, please refer to the appendix.

[0057] Specifically, during the operation of this equipment, when the live fish falls onto the upper part of the first conveyor 5, the first electric push rod 607 in the stunning and side-cutting mechanism 6 is activated, causing its rod to drive the angle plate 608 downward, so that the angle plate 608 presses the live fish longitudinally. Then, the first motor 603 is activated, driving the worm gear 604 to rotate, which in turn drives the worm wheel 605 to rotate the live fish 90 degrees, thus changing the fish's posture to lateral. Afterwards, the second bidirectional linear module 609 is activated, simultaneously adjusting the distance between the two moving blocks 610 to accommodate the fish's length. Finally, the two pneumatic... When the cylinder 611 operates, it can drive the hammer 612 to strike the fish's head several times, achieving a stunning effect. By setting two hammers 612 on the left and right sides to strike the fish, it is to ensure that the fish's head can be struck in different directions, improving the fault tolerance of the strike. After the fish is stunned, the first motor 603 is restarted, causing the worm gear 604 to drive the worm wheel 605 to rotate, so that the fish's belly faces the first electric slide rail 613. Then, the cutting machine 614 is started, and the first electric slide rail 613 drives the cutting machine 614 to move and cut open the fish's belly. At this time, the steps of stunning and cutting the live fish are completed.

[0058] For further details, please refer to the appendix. Figure 10 - Appendix Figure 11The fish scale and belly processing mechanism 7 includes a U-shaped frame 701 fixedly installed at the rear top of the connecting frame 3. A second motor 702 is fixedly installed on one side of the U-shaped frame 701. A first turntable 703 is fixedly connected to the output end of the second motor 702. A second electric slide rail 704 is fixedly installed on one side of the first turntable 703. A second turntable 705 is rotatably connected to the inside of the U-shaped frame 701. A linear module 706 is slidably connected to one side of the second turntable 705. One end of the linear module 706 is fixedly connected to the movable seat of the second electric slide rail 704. A semi-circular arc tube 707 is fixedly installed on the movable platform of the linear module 706. Several rotating nozzles are equidistantly installed on the part. A third motor 708 is fixedly installed on one side of the rear part of the connecting frame 3. The output end of the third motor 708 is fixedly connected to a third electric slide rail 709.

[0059] Specifically, after the fish belly is cut open, the first conveyor 5 is activated to send the fish to the scale and belly processing mechanism 7. The third motor 708 inside the mechanism 7 drives the third electric slide rail 709 to rotate. Activating the third electric slide rail 709 adjusts the distance between the two electric grippers 710 to accommodate the fish's length. The two electric grippers 710 then lift the fish from its head and tail. The third motor 708 then drives the third electric slide rail 709 to rotate, raising the fish. Multiple high-pressure rotating nozzles on the semi-circular tube 707 then spray high-pressure water into the gaps in the fish scales and the cut belly. During this process, by adjusting the position of the semi-circular tube 707 and by changing the rotation position of the linear module 706 via the second motor 702, multi-angle spraying of the fish can be achieved, removing the scales and internal organs from the belly. The fish is flushed out and falls into the receiving tray 711. Two side baffles 714 are provided to prevent water and fish scales and entrails from splashing.

The water source for the semi-circular tube 707 is supplied by external equipment. After cleaning the fish scales and belly, the third motor 708 is started again to change the rotation position of the third electric slide rail 709. At the same time, the rotation of the gear 713 drives the rack 712 to move the receiving tray 711 synchronously. When the electric gripper 710 clamps the fish and sends it to the second conveyor 12, the receiving tray 711 moves forward to make room. When the electric gripper 710 rotates, it moves backward to return to its original position. When the fish is conveyed to the top of the second conveyor 12, the cleaning of the fish scales and belly is completed.

[0061] Specifically, after the fish is conveyed to the anvil 13 by the second conveyor 12, the spacing between the cutting blades 904 can be adjusted according to the processing needs of the fish product by activating the variable spacing module 903 in the variable spacing fish cutting mechanism 9. After the cutting spacing is confirmed, the hydraulic rod 902 is activated, which moves the entire variable spacing module 903 downward. When the variable spacing module 903 moves downward, the pulleys 908 at the bottom of the inclined pressure rods 906 on both sides will first contact the surface of the anvil 13 and spread out to both sides. The elastic pressure line 907 between the front and rear inclined pressure rods 906 on both sides will press on the fish, achieving a soft fixing effect and pre-fixing the fish. Then the hydraulic... As the lever 902 continues to press down, it will drive the variable pitch module 903 and the multiple fish-cutting knives 904 installed below it to cut the fish into sections. After the sections are cut, the hydraulic lever 902 retracts, and the inclined pressure levers 906 on both sides will also return to their original positions under the action of the damping spring shaft, ready for the next auxiliary fixing operation. After the fish is cut into sections, the second electric push rod 15 is activated to drive the push plate 16 to move, which will send the cut fish sections on the anvil 13 onto the U-shaped conveyor 14 and transport them to the cleaning tray 1. If the fish does not need to be cut into sections, the second conveyor 12 is activated to reverse the transport, and the fish will fall directly into the cleaning tray 1 for subsequent cleaning operations.

[0062] For further details, please refer to the appendix. Figure 15 The gas suction mechanism 10 includes a base box 1001 installed in the middle of the rear frame 2. Multiple exhaust fans 1002 are installed at equal intervals on the upper front side of the base box 1001. Gas supply pipes 1003 are installed on both sides of the base box 1001. A suction box 1004 is installed at one end of the gas supply pipe 1003.

[0063] Specifically, during the fish-cutting process, by activating the multiple exhaust fans 1002 and the suction box 1004 in the gas suction mechanism 10, some of the fishy smell can be extracted, thus helping to reduce the fishy odor in the equipment operating area.

[0064] A U-shaped conveyor 14 for conveying cut fish pieces is installed between the cleaning tray 1 and the anvil 13. A second electric push rod 15 is fixedly installed on one side of the rear frame 2. A push plate 16 for pushing the cut fish pieces into the U-shaped conveyor 14 is fixedly connected to the front end of the second electric push rod 15. A fourth motor 17 is fixedly installed in the middle of the front side of the bottom end of the connecting frame 3. A stirring blade 18 is fixedly connected to the output end of the fourth motor 17. A drain pipe 19 is installed at one end of the water receiving tray 11 and one side of the outer wall of the drain pipe 19 is connected to the inside of the cleaning tray 1. A solenoid valve is installed at the connection between the cleaning tray 1 and the water receiving tray 11. The front top of the water receiving tray 11 is fixedly connected to the rear bottom of the cleaning tray 1.

[0065] In this embodiment, after the cut fish pieces are sent into the cleaning pan 1, clean water is injected into the cleaning pan 1 through an external water injection device, and then the fourth motor 17 is started to drive the stirring blade 18 to operate, so as to clean the fish pieces inside the cleaning pan 1. After cleaning is completed or the equipment is shut down for maintenance, the water inside the cleaning pan 1 and the water receiving pan 11 can be discharged at the same time by opening the solenoid valve connected between the drain pipe 19 and the cleaning pan 1 and the water receiving pan 11.

[0066] The integrated fish-killing and washing equipment provided in this embodiment has a high degree of integration and can perform processes such as stunning, side cutting, cleaning fish scales and belly, and cutting into sections on fresh live fish. The fish body is well processed and the fish meat is intact. It is suitable for continuous operation and production in fish meat processing plants.

[0067] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
