DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and examples, but they are not intended to limit the present invention.

[0026] Example: A fish belly cleaning device for an automated production line for live fish processing includes a conveyor line 1, on which a group of conveyor belts 2 for clamping and conveying fish forward are installed. Figure 1 As shown, the eviscerated live fish is held and conveyed by conveyor belts on both sides, with the opening of the fish belly facing downward. The conveyor belts are placed upright, with ribs at the end of the conveyor belts supporting the fish body. A flat conveyor belt is set at the discharge port of the conveyor belts, which transports the rinsed fish forward to the slide at the front end. The conveyor line 1 is equipped with a top frame 3, and the lower surface of the top frame 3 is equipped with a positioning mechanism 41 for limiting the position of the fish and an external shower nozzle assembly 4 for cleaning the surface of the fish, as shown in the attached figure. Figure 2 As shown, the external shower nozzle assembly includes a liquid outlet pipe with multiple liquid outlet nozzles, which can flush the mucus on the outside of the fish body and the blood when the internal organs are removed through the external shower nozzle assembly; the positioning mechanism 41 includes two groups of translation assemblies 13 arranged on the lower surface of the top frame 3, and the translation assembly is mainly composed of a motor, a screw and a moving block. The rotation of the motor drives the screw to rotate to realize the movement of the moving block. A lifting cylinder 14 is installed at the moving end of the translation assembly 13, and the protruding end of the lifting cylinder 14 has a positioning block 15 that fits with the head and tail of the fish, as shown in the attached figure. Figure 3As shown, the positioning block 15 includes a plate surface 16 connected to the protruding end of the lifting cylinder 14. The lower part of the plate surface 16 is installed with mutually symmetrical inner arc blocks 17. The large opening between the inner arc blocks 17 on both sides faces the fish head and fish tail. The inner arc blocks are symmetrically arranged, and the spacing between the two ends of the two inner arc blocks is different. The opening facing the fish head and fish tail is larger, and the other end is smaller. The fish head and fish tail enter from the large opening end and then extend from the small opening end. In order to fit the different structures of the fish head and fish tail, the spacing between the inner arc blocks on both sides at the front end is larger, and the spacing between the inner arc blocks on both sides at the rear end is smaller. Through the positioning of the positioning blocks, the entire fish body is firmly aligned. When the positioning mechanism is in operation, the lifting cylinder first drives the positioning block to descend, and then the translation assembly drives the positioning block to move toward the fish body. The positioning block at the front end positions the fish head, and the positioning block at the rear end positions the fish tail.

[0027] The bottom of the conveyor line 1 is provided with a bottom plate 5, a carrying cylinder 6 is provided below the bottom plate 5, a flat plate 7 is provided on the extended end of the carrying cylinder 6, and an expansion power member 8 is provided in the middle of the flat plate 7. Figure 6 As shown, an expansion moving member 9 for expanding the fish belly is provided on the flat plate 7 and on both sides of the expansion power member 8. Figure 5As shown, the output end of the expansion power member 8 is abutted against the input end of the expansion moving member 9; the expansion power member 8 includes a rotating motor 18 provided on the flat plate 7, and the output end of the rotating motor 18 is connected to a cam block 19, which has a short end and a long end. Under normal conditions, the short end of the cam block abuts against the input end of the expansion moving member. When the fish belly needs to be opened, the cam block rotates, and the long end of the cam block abuts against the input end of the expansion moving member, thereby pulling apart the distance between the expansion moving members on both sides. The expansion moving member 9 includes a lateral frame 20 provided on the flat plate 7, and a cross bar 21 is provided on the lateral frame 20. The end of the cross bar 21 has a ball 22 abutting against the cam block 19, and a spring 23 is provided between the ball 22 and the lateral frame 20, which is sleeved on the cross bar 21. The spring is mainly used to reset, and a spacing adjustment component 24 is installed at one end of the cross bar 21, and a spacing adjustment component 24 is installed at the movable end. The support hook 25 is used to support the belly of the fish. The spacing adjustment component 24 includes a rod frame 26 connected to one end of the cross bar 21. Support shafts 27 are installed on both sides of the rod frame 26. The lateral frame 20 has a transverse groove 28 that fits with the support shaft 27. When the rod frame moves, the support shaft will move along the transverse groove. An adjusting motor 29 is installed at one end of the rod frame 26. A guide rod 30 and a bidirectional screw 31 are installed in the rod frame 26. The output end of the adjusting motor 29 is connected to the bidirectional screw 31. The bidirectional screw has threads with different rotation directions at both ends. A moving block 32 is installed on the guide rod 30 and the bidirectional screw 31. The support hook 25 is set on the moving block 32. The expansion moving part is equipped with a spacing adjustment component, which can flexibly adjust the spacing of the support hooks according to the size of different fish bodies and the size of the fish belly opening. It has strong applicability. When in use, the adjusting motor will drive the bidirectional screw to rotate, and the moving blocks on both sides move in different directions, thereby realizing the spacing adjustment between the two moving blocks.

[0028] A protective frame 10 is installed on the flat plate 7 and above the expansion power member 8. Figure 4 As shown, the protective frame can also block the water flow from the lower flushing and provide some protection for the rotating motor below. A nozzle swing mechanism 11 is installed on the protective frame 10. An internal nozzle 12 for flushing the inside of the fish belly is installed on the swing end of the nozzle swing mechanism 11. The nozzle swing mechanism 11 includes a main frame 33 provided on the protective frame 10, as shown in the attached figure. Figure 8 As shown, a swing member 34 is provided in the main frame 33, and the output end of the swing member 34 is connected to the swing frame 35. The internal nozzle 12 is provided at the end of the swing frame 35. Figure 7As shown, the swing member 34 includes a swing cylinder 36 disposed within the main frame 33. A track frame 37 is mounted within the main frame 33, and a rack 38 is mounted within the track frame 37. The rack 38 is connected to the protruding end of the swing cylinder 36. A shaft 39 is provided at the upper end of the main frame 33 via a bearing. A gear 40 is provided on the shaft 39 and meshes with the rack 38. The swing frame 35 is connected to the shaft 39. The swing cylinder drives the rack to move, and the rack and gear mesh, causing the swing frame to oscillate back and forth. This allows the internal nozzle to achieve multi-angle cleaning, covering every corner of the fish's belly. The internal structure of a fish's belly is complex, with wrinkles and depressions. The swinging nozzle allows the water flow to impact these areas from all directions and angles, thoroughly removing residual blood, internal organs, and other dirt, avoiding blind spots. During the swinging process, the internal nozzle's flushing angle continuously changes, and the direction of the water flow impacting the inner wall of the fish's belly also changes accordingly. Compared with fixed-angle flushing, this dynamically changing water flow impact can generate greater force and more effectively remove stubborn dirt attached to the inner wall of the fish's belly. Especially for some tightly adhered tissues, the multi-angle water flow impact brought by the swinging nozzle can significantly enhance the flushing force and improve the thoroughness of cleaning.

[0029] The working principle of the present invention is as follows: the live fish with the internal organs removed is clamped by the conveyor belts 2 placed upright on both sides, and the fish is transported forward with its belly opening facing downward. The ribs at the end of the conveyor belt 2 support the fish body. When the fish reaches the washing station, the conveyor belt 2 stops running. At this time, the positioning mechanism 41 on the surface of the top frame 3 is activated, and the lifting cylinder 14 extends, driving the positioning block to move to the corresponding height of the fish body. The motors in the two sets of translation assemblies 13 drive the screws to rotate, so that the lifting cylinder 14 at the movable end moves to the positions corresponding to the head and tail of the fish, and the positioning block 15 It fits with the fish head and tail; the positioning blocks 15 at the front and rear ends respectively fix the fish head and tail, firmly aligning the fish body and providing a stable foundation for subsequent cleaning; after the fish body is positioned, the external shower nozzle assembly 4 starts to work, and the multiple liquid outlet nozzles on its liquid outlet pipe spray water at the same time to wash away the mucus on the surface of the fish body and the blood remaining when the internal organs are removed, quickly removing the dirt on the surface of the fish body; after the surface cleaning is completed, the feed cylinder 6 at the bottom of the conveyor line 1 is started, pushing the flat plate 7 to rise, so that the expansion power part 8 and the expansion moving part 9 on the flat plate 7 are close to the belly of the fish, and the rotating motor 18 in the expansion power part 8 drives the cam block 19 to rotate. When the long end of the cam block 19 is aligned with the expansion moving part 9, the rotation of the cam block 19 is stopped. When the input ends (the spheres 22 at the ends of the crossbar 21) of the expansion movable members 9 are in contact with each other, the expansion movable members 9 on both sides are pushed to move toward the sides of the fish body, and the support hooks 25 of the expansion movable member 9 are stuck in the belly of the fish. As the expansion movable member 9 moves, the fish belly is gradually expanded. In this process, if it is necessary to adjust the spacing of the support hooks 25 according to the size of the fish body or the opening of the fish belly, the adjustment motor 29 drives the bidirectional screw 31 to rotate, so that the moving blocks 32 on both sides move in different directions along the guide rod 30, thereby realizing flexible adjustment of the spacing of the support hooks 25; the fish belly support After opening, the nozzle swing mechanism 11 on the protective frame 10 starts to operate, and the swing cylinder 36 extends or retracts, driving the rack 38 in the track frame 37 to move, and the gear 40 engaged with the rack 38 rotates accordingly, thereby causing the shaft 39 to drive the swing frame 35 and the internal nozzle 12 to swing. During the swinging process, the internal nozzle 12 sprays water into the fish belly at multiple angles and in all directions, flushing the folds, depressions and other parts in the complex structure inside the fish belly, and completely removing residual blood, internal organs and other dirt.
