[0021] (III) Beneficial effects

[0022] Compared with the prior art, the utility model provides a multifunctional fish killing machine, which has the following beneficial effects:

[0023] 1. The multifunctional fish killing machine can use the fish pressing component to apply a downward force to the corresponding sliding sleeve when the fish is scaled by the scaling component, so that the corresponding fixed shaft can drive the conical gear wheel thereon to move downward, and the front end of the fish can be pressed by the two conical gear wheels moving downward, so that the fish will not be deflected by the force of the scaling component, further improving the scaling effect and operation stability. This avoids the problem of uneven scaling or damage to fish meat caused by the deviation of fish due to uneven force during the scaling process in the traditional method, and also improves the stability of scaling, the protection effect of fish meat and the reliability of the equipment.

[0024] 2. The multifunctional fish killing machine can, through the fish feeding assembly provided, enter the V-shaped material channel after the fish has been scaled, and can drive the corresponding sprocket shaft to rotate by rotating the corresponding transmission shaft in the motor gearbox assembly. When the sprocket shaft rotates, it can drive the chain and the C-shaped teeth thereon to operate together. At this time, the spring in the C-shaped sliding sleeve frame can drive the sliding sleeve to be ejected, so that the chains on the two fish feeding assemblies can be clamped toward the center position, thereby clamping the fish on the V-shaped material channel. At this time, the running chain and C-shaped teeth can drive the fish forward until they contact the cutting blade of the cutting motor in the fish meat cutting assembly to cut the fish. At this time, the two fish pressing plates provided can clamp the fish on both sides of the cutting blade of the cutting motor, which enables the fish to be stably fixed during cutting, thereby avoiding the need for manual fish feeding and cutting in the traditional method, which is inefficient and has safety hazards, and at the same time improves the automation degree, processing efficiency and operation safety of fish meat processing.

[0025] 3.

At this time, the corresponding transmission shaft in the motor-gearbox assembly will drive the two gears to rotate inward at the same time through the spring fixed shaft, so that the variable diameter spring thereon can rotate together. When the variable diameter spring rotates, the multiple scale scraping gaskets thereon can contact the scales of the fish in the opposite direction, so as to scrape off the scales. At this time, the fish located between the two variable diameter springs will drive the two variable diameter springs to deform, so as to better fit the overall shape of the fish, so as to achieve a better scale scraping effect. This avoids the problem that the fixed scale scraping tool used in the traditional method cannot adapt to fish of different sizes, resulting in poor scale scraping effect or damage to the fish meat. At the same time, it also improves the scale scraping effect, adaptability to fish of different sizes and the degree of automation of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The two spring fixed shafts 12 on the lower side are both rotatably connected to the workbench 1, and the spring fixed shaft 12 on one side is fixedly connected to the corresponding transmission shaft in the motor gearbox assembly 7. The two variable diameter springs 14 are fixedly sleeved on the variable diameter part near the upper end with a plurality of spacer solid sleeves 17, and the plurality of spacer solid sleeves 17 are evenly distributed on the variable diameter part of the variable diameter spring 14 at equal intervals.

[0045] Furthermore, when in use, the motor-gearbox assembly 7 is started, and the corresponding transmission shaft in the motor-gearbox assembly 7 rotates, and the fish-feeding device 25 moves the fish toward the scale-scraping assembly. At this time, the corresponding transmission shaft in the motor-gearbox assembly 7 drives the two gears 16 to rotate inward at the same time through the spring fixing shaft 12, so that the variable diameter spring 14 thereon can rotate together. When the variable diameter spring 14 rotates, the multiple scale-scraping gaskets 15 thereon can contact the scales of the fish in the opposite direction, thereby scraping off the scales. At this time, the fish located between the two variable diameter springs 14 will drive the two variable diameter springs 14 to deform, so as to better fit the overall shape of the fish, so as to achieve a better scale-scraping effect.

[0047] Furthermore, the fish feeding assembly provided can enter the V-shaped material channel 26 after the fish has been scaled, and the corresponding transmission shaft in the motor gearbox assembly 7 can be rotated to drive the corresponding sprocket shaft 5 to rotate. When the sprocket shaft 5 rotates, it can drive the chain 8 and the C-shaped teeth 9 thereon to operate together. At this time, the spring in the C-shaped sliding sleeve frame 3 can drive the sliding sleeve 4 to be ejected, so that the chains 8 on the two fish feeding assemblies can be clamped toward the center position, thereby clamping the fish on the V-shaped material channel 26. At this time, the running chain 8 and C-shaped teeth 9 can drive the fish forward until they contact the cutting blade of the cutting motor 24 in the fish meat cutting assembly to cut the fish. At this time, the two fish pressing plates 11 provided can clamp the fish on both sides of the cutting blade of the cutting motor 24, which allows the fish to be stably fixed during cutting. This avoids the need for manual fish feeding and cutting in the traditional method, which is inefficient and has safety hazards, and at the same time improves the degree of automation, processing efficiency and operational safety of fish meat processing.

[0048] Working principle: when in use, the motor-gearbox assembly 7 is started, and the corresponding transmission shaft in the motor-gearbox assembly 7 rotates, and the fish-feeding device 25 moves the fish toward the scale-scraping assembly. At this time, the corresponding transmission shaft in the motor-gearbox assembly 7 drives the two gears 16 to rotate inward at the same time through the spring fixing shaft 12, so that the variable diameter spring 14 thereon can rotate together. When the variable diameter spring 14 rotates, the multiple scale-scraping gaskets 15 thereon can contact the scales of the fish in the opposite direction, so as to scrape off the scales. At this time, the fish located between the two variable diameter springs 14 will drive the two variable diameter springs 14 to deform, so as to better fit the overall shape of the fish, so as to achieve a better scale-scraping effect.

[0049] Furthermore, the fish pressing assembly can, when the fish is being scaled by the scaler assembly, have two vertical springs 23 apply a downward force to the corresponding sliding sleeve 19, so that the corresponding fixed shaft 20 can drive the conical gear 21 thereon to move downward, and the front end of the fish can be pressed by the two conical gears 21 moving downward, so that the fish will not be deflected by the force of the scaler assembly.

[0050] Furthermore, the fish feeding assembly can enter the V-shaped material channel 26 after the fish is scaled, and the corresponding transmission shaft in the motor gearbox assembly 7 can be rotated to drive the corresponding sprocket shaft 5 to rotate. When the sprocket shaft 5 rotates, it can drive the chain 8 and the C-shaped teeth 9 thereon to operate together. At this time, the spring in the C-shaped sliding sleeve frame 3 can drive the sliding sleeve 4 to be ejected, so that the chains 8 on the two fish feeding assemblies can be clamped toward the center position, thereby clamping the fish on the V-shaped material channel 26. At this time, the running chain 8 and C-shaped teeth 9 can drive the fish forward until they contact the cutting blade of the cutting motor 24 in the fish meat cutting assembly to cut the fish. At this time, the two fish pressing plates 11 set can clamp the fish on both sides of the cutting blade of the cutting motor 24, which allows the fish to be stably fixed during cutting.
