A first transmission member is mounted on the first driven wheel 22 and the driving wheel 211. The third driving member 21 drives the driving wheel 211 to rotate. The driving wheel 211 drives the first driven wheel 22 to rotate via the first transmission member, thereby driving the first driven roller 24 to rotate via the third mounting shaft 23, and then driving the first conveyor belt 25 to move.

[0029] The second conveyor assembly 3 also includes a second driven wheel 31, a third driven wheel 32, a fourth driven wheel 34, a fourth mounting shaft 351, and at least two second driven rollers 35. The second conveyor belt 36 is mounted on the second driven rollers 35. Two second driven rollers 35 are located within the space enclosed by the second conveyor belt 36 and at both ends of the second conveyor belt 36. The remaining second driven rollers 35 are located along the travel path of the second conveyor belt 36, thereby guiding and supporting the second conveyor belt 36.

Of the at least two second driven rollers 35, one located at the end of the second conveyor belt 36 is connected to the fourth mounting shaft 351, allowing the fourth mounting shaft 351 to drive the second driven roller 35 in rotation. The third drive member 21 rotates the third mounting shaft 23, which in turn rotates the second driven wheel 31. The second driven wheel 31, via the second transmission member, rotates the third driven wheel 32, thereby rotating the fourth driven wheel 34. The fourth driven wheel 34 rotates the fourth mounting shaft 351, which in turn rotates the second driven roller 35, thereby moving the second conveyor belt 36. In this embodiment, the first and second conveyor belts 25 and 36 can be driven solely by the third drive member 21, eliminating the need for two drive members. In this embodiment, the first, second, third, and fourth driven wheels 22, 31, 32, and 34 are all considered sprockets, and the first and second transmission members are both considered chains that cooperate with the driven wheels.

The top side of the container and the side close to the conveying channel are both provided with openings. The cutting knife 53 and the cleaning brush 43 are both located in the accommodating space, so that the debris and minced meat generated by the cutting knife 53 in the process of cutting the fish and the cleaning brush 43 in the process of cleaning the cut fish can enter the accommodating space, thereby preventing the debris and minced meat from splashing to the outside.

[0038] The fish killing device also includes a discharge piece 7, which is located at the input end of the first conveyor belt 25. The first conveyor belt 25 passes through the discharge piece 7, and the conveying side of the first conveyor belt 25 is coplanar with the bottom of the discharge piece 7. The conveying side of the first conveyor belt 25 is located in the discharge space. The discharge piece 7 is used to accommodate the fish to be cut, and move the fish to be cut onto the first conveyor belt 25 so that the first conveyor belt 25 drives the fish to be cut to move.

[0039] Reference Figure 2As shown, the fish killing device also includes a guide plate 9, which is connected to the support frame 1. The end face of the guide plate 9 is U-shaped and is located at the output end of the conveying channel. The cut fish is moved to the outside through the guide plate 9.

[0040] During use, the fish to be cut is placed in the discharge member 7, and the fish to be cut moves onto the first conveyor belt 25 and enters the conveying channel through the first conveyor belt 25. The belly of the fish to be cut faces the direction of the cutting knife 53. When the fish to be cut passes through the clamping space, the fish to be cut squeezes the first limiting roller 63 and the second limiting roller 65 in the direction away from each other. At this time, the first elastic member 611 and the second elastic member 613 are compressed. During the movement of the first limiting roller 63 and the second limiting roller 65, the first rack 66 and the second rack 67 drive the gear 68 to rotate, and the first limiting roller 63 and the second limiting roller 65 have the same moving distance, and at the same time, the first driving member 52 drives the cutting knife 53 to rotate, and the cutting knife 53 cuts the fish to be cut. When the cut fish leaves the clamping space, the first elastic member 611 drives the second limiting roller 65 to reset, and the second elastic member 613 drives the first limiting roller 63 to reset. In the process of conveying the cut fish through the conveying channel, the second driving member 42 drives the cleaning brush 43 to rotate, and the cleaning brush 43 cleans the cut fish. Finally, the cut fish moves to the outside through the guide plate 9.

[0041] A fish killing device of the present invention has a gear 68 meshing between the first rack 66 and the second rack 67, so that during the movement of the first movable plate 62 and the second movable plate 64, the meshing of the gear 68 and the rack makes the movement distance of the first movable plate 62 and the second movable plate 64 the same, thereby making the belly of the fish to be cut always remain in the middle position in the vertical direction of the clamping space, so that the cutting knife 53 can cut the middle position of the fish belly, and there is no need to classify the fish by size before cutting, thereby improving the efficiency of fish killing.
