Description

Technical Field

[0001] This invention relates to the field of aquatic product processing technology, specifically to an intelligent automatic fish-killing machine. Background Technology

[0002] my country is the world's largest freshwater fish farmer and consumer, accounting for over 60% of global freshwater aquaculture production. Scale, gut, and clean live fish are crucial steps connecting farmers and consumers. Currently, the initial processing of live fish is primarily manual, which suffers from high labor intensity, low efficiency, high safety risks, inconsistent processing quality, and high labor costs. A skilled worker can only kill one fish in 3-5 minutes, and frequent use of knives easily leads to cuts. The damp working environment also poses food safety and electric shock hazards. This has led to the development of mechanized automatic fish-killing machines to replace manual labor, such as the Chinese utility model patent application number 201910140894.7, entitled "A Fully Automatic Fish-Killing Machine for Automatically Cleaning Fish Scales and Internal Organs." The new patented technology enables fully automated fish cleaning, including the removal of scales and viscera, in a single operation. This overcomes the shortcomings of traditional manual fish cleaning, which is labor-intensive and inefficient. However, it still has some technical limitations. For example, it has poor adaptability to different sizes and varieties of fish, making flexible processing impossible. Problems such as incomplete scaling, uncontrolled gutting depth, gallbladder rupture, and viscera residue can easily occur, resulting in fish meat loss. The equipment often uses 220V AC mains power, posing a serious risk of electric shock in humid processing environments. Furthermore, the high power of the drive motor and the high overall power consumption of the machine increase the electricity consumption threshold and operating costs. In addition, the existing equipment does not consider the resource utilization of processing waste, which can easily cause environmental pollution and is difficult to adapt to the diversified processing needs of retail and catering industries. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an intelligent automatic fish-killing machine, which solves the problems of existing fish-killing equipment such as single function, inability to achieve full-process automated processing, poor fish body adaptability, insufficient safety redundancy, high power consumption, and lack of resource processing function.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an intelligent automatic fish-killing machine, comprising a frame assembly, a fish processing platform in the middle of the frame, and a fish inlet and a fish outlet at both ends of the fish processing platform. The fish to be processed enters from the fish inlet with its head facing forward and its belly facing down. Along the conveying direction, an adaptive fish scaling device, an adaptive feeding device, a fish gutting device, a fish belly opening device, a fish viscera cleaning device, a fish belly cleaning device, an adaptive output device, and a fish outlet are arranged in sequence. A limit device and a fish scale rinsing nozzle are correspondingly arranged above the fish gutting device, and a high-pressure water spray nozzle is correspondingly arranged below the fish belly cleaning device.

[0005] Further improvements are made in that: the adaptive fish scale removal device consists of two symmetrically arranged elastic descaling rollers with an adaptive adjustment range of 20-150mm between them; the elastic descaling rollers are equipped with a safety reduction DC motor and an elastic roller plate, which is a food-grade 304 stainless steel spring, and the spring is fitted with closely arranged anti-loosening nuts, the edges of which protrude to form a scraping blade.

[0006] Further improvements are made in that: the adaptive input device and the adaptive output device are the same size and shape, and each consists of two symmetrically arranged elastic conveying rollers with an adaptive adjustment range of 0-120mm for their spacing; the elastic conveying rollers are equipped with a safety reduction DC motor and multiple sets of symmetrically arranged star-shaped dials, which are made of food-grade anti-slip rubber.

[0007] A further improvement is that the fish gutting device is equipped with a safety reduction DC motor and a saw blade, wherein the safety reduction DC motor drives the saw blade to rotate, and the vertical adaptive adjustment stroke of the saw blade is 0-80mm.

[0008] A further improvement is that a V-shaped fish belly support plate is provided at the rear of the saw blade. The fish belly support plate is a 0.5mm thick 304 stainless steel sheet with a V-shaped opening angle of 60°. It is fixedly connected to the fish processing platform by multiple bolts.

[0009] A further improvement is that the fish viscera cleaning device is equipped with a safety reduction DC motor, a fish viscera scraper, and a lifting mechanism. The safety reduction DC motor drives the lifting mechanism, which in turn causes the fish viscera scraper to move up and down in the vertical direction.

[0010] A further improvement is that the fish belly cleaning device is equipped with a safety reduction DC motor and a cleaning brush, wherein the safety reduction DC motor drives the cleaning brush to rotate, and the cleaning brush has an adaptive adjustment stroke of 0-80mm in the vertical direction.

[0011] A further improvement is made in that: the limiting device includes a fish back limiting plate and an elastic adaptive adjustment device, wherein the V-shaped opening of the fish back limiting plate is pressed against the fish back, the upper part of the fish back limiting plate is fixedly connected to the elastic adaptive adjustment device, and the elastic adaptive adjustment device is fixedly connected to the corresponding position of the frame.

[0012] A further improvement is that an internal organ pulverizing device is provided at the lower part of the frame, and the internal organ pulverizing device is connected to the filter drainage device through a guide channel.

[0013] A further improvement is that the viscera pulverizing device includes a safety-reduced DC motor, a stirring blade, a stirring tank, and an auxiliary material conveying device. The safety-reduced DC motor is located above the stirring tank, the stirring blade is inserted into the stirring tank, the safety-reduced DC motor drives the stirring blade to rotate, and the auxiliary material conveying device is located at a corresponding position on the upper part of the stirring tank.

[0014] The beneficial effects of this invention are as follows: The present invention discloses an intelligent automatic fish-killing machine, which solves the problems of existing fish-killing equipment, such as limited functionality, inability to achieve fully intelligent and automated processing, poor fish adaptability, insufficient safety redundancy, high power consumption, and lack of resource recovery capabilities. Specific beneficial effects are as follows: 1. Achieve fully integrated intelligent and automated operation throughout the entire process. It innovatively integrates a camera intelligent detection module with six core processing stations: scaling, gutting, removing internal organs, cleaning, and recycling internal organs. It can achieve fully automated operation throughout the entire process, including "automatic specification recognition, automatic parameter matching, one-time feeding, and finished product output". The processing time for a single fish is ≤30 seconds. It can completely replace manual slaughtering, eliminate the need for secondary processing, significantly improve processing efficiency, and reduce labor costs and labor intensity. 2. The all-station adaptive and flexible design features adaptive adjustment mechanisms at five key stations: conveying, descaling, gutting, limiting, and cleaning. Combined with the intelligent control module's intelligent regulation system, it can dynamically adjust the opening and closing degree of components and processing parameters according to the thickness, width, and height of the fish. Without manual intervention, it can achieve precise and flexible processing of common freshwater fish of all sizes from 1 to 7 catties, solving the core pain points of poor adaptability and easy damage to fish bodies of traditional equipment. The descaling rate is ≥98%, the gutting is precise without gallbladder damage, the internal organ removal rate is ≥99%, and the processing quality is stable. 3.

It can be adapted to battery-powered mobile processing scenarios, and the safety and energy saving are significantly improved. 4. The integrated design for resource utilization innovatively integrates an internal organ crushing and recycling device. While completing the slaughtering and processing, it performs in-situ reduction and resource utilization of fish internal organ waste. Fish internal organs can be mixed with feed additives to make feed raw materials, which not only solves the problems of environmental pollution and high treatment costs of aquatic product processing waste, but also realizes the value-added utilization of waste, combining economic and environmental benefits.

[0018] See Figures 1 to 11 As shown, this embodiment of the invention provides an intelligent automatic fish-killing machine, which has a frame 8. A fish processing platform 10 is arranged in the middle of the frame 8. The fish processing platform 10 has a fish inlet 7 and a fish outlet 15 at both ends. The fish to be processed enters from the fish inlet 7 with the head facing forward and the belly facing down. Along the conveying direction, an adaptive fish scale removal device, an adaptive feeding device, a fish gutting device, a fish belly opening plate 12, a fish internal organ cleaning device, a fish belly cleaning device, an adaptive output device, and a fish outlet 15 are arranged in sequence.

The smart control module 9 is connected to the smart camera 11, the adaptive fish scaler, the adaptive input device, the fish gutting device, the fish viscera cleaning device, the fish belly cleaning device, and the adaptive output device via cables.

[0019] See Figure 3 As shown, the adaptive fish scale removal device consists of two symmetrically arranged elastic descaling rollers 6, the spacing of which is adaptively adjustable from 20 to 150 mm. The elastic descaling roller 6 is equipped with a safety reduction DC motor 21 and an elastic roller 28. The elastic roller 28 is a food-grade 304 stainless steel spring, and a tightly arranged anti-loosening nut is threaded through the spring. The edge of the anti-loosening nut protrudes to form a scraping blade.

[0020] See Figure 2As shown, the adaptive input device and the adaptive output device are the same size and shape, and each consists of two symmetrically arranged elastic conveying rollers 5, with an adaptive adjustment range of 0-120mm for their spacing; the elastic conveying rollers 5 are equipped with a safety reduction DC motor 21 and multiple sets of symmetrically arranged star-shaped dials 29, which are made of food-grade anti-slip rubber.

[0021] See Figure 8 As shown, the fish gutting device is equipped with a safety reduction DC motor 21 and a saw blade 26. The safety reduction DC motor 21 drives the saw blade 26 to rotate, and the vertical adaptive adjustment stroke of the saw blade 26 is 0-80mm.

[0022] See Figure 1 As shown, a V-shaped fish belly support plate 12 is provided at the rear of the saw blade 26. The fish belly support plate 12 is a 0.5mm thick 304 stainless steel sheet with a V-shaped opening angle of 60°. It is fixedly connected to the fish processing platform 10 by multiple bolts.

[0023] See Figure 7 As shown, the fish viscera cleaning device is equipped with a safety reduction DC motor 21, a fish viscera scraper 25, and a lifting mechanism. The safety reduction DC motor 21 drives the lifting mechanism, which in turn drives the fish viscera scraper 25 to move up and down in the vertical direction.

[0024] See Figure 9 As shown, the fish belly cleaning device is equipped with a safety reduction DC motor 21 and a cleaning brush 27. The safety reduction DC motor 21 drives the cleaning brush 27 to rotate, and the cleaning brush 27 has an adaptive stroke of 0-80mm in the vertical direction.

[0025] See Figure 6 As shown, the limiting device includes a fish back limiting plate 19 and an elastic adaptive adjustment device. The V-shaped opening of the fish back limiting plate 19 is pressed against the fish back. The upper part of the fish back limiting plate 19 is fixedly connected to the elastic adaptive adjustment device, which is fixedly connected to the corresponding position of the frame 8.

[0026] See Figure 1 As shown, an internal organ pulverizing device 18 is provided at the lower part of the frame 8, and the internal organ pulverizing device 18 is connected to the filter drainage device 1 through a guide channel 17.

[0027] See Figure 4As shown, the viscera pulverizing device 18 includes a safety reduction DC motor 21, a stirring blade 22, a stirring tank 23, and an auxiliary material conveying device 16. The safety reduction DC motor 21 is located above the stirring tank 23, the stirring blade 22 is inserted into the stirring tank 23, the safety reduction DC motor 21 drives the stirring blade 22 to rotate, and the auxiliary material conveying device 16 is located at the corresponding position on the upper part of the stirring tank 23.

[0028] In addition, the adaptive fish scale removal device, adaptive input device, fish belly opening device, fish belly opening plate 12, fish viscera cleaning device, fish belly cleaning device, adaptive output device, and limiting device described in this invention are all existing mature technologies. Their structures, functions, and uses are not described in detail in this specification, but are technologies known in the field.

[0029] The working principle of this invention is as follows: 1. Intelligent detection of fish body size: The fish to be processed is placed on the fish body detection table 14, and the intelligent camera 11 captures the image of the fish body. The image is processed by the intelligent control module 9, which automatically calculates the length, width and aspect ratio of the fish body, matches the preset parameter library, and automatically sends speed control commands to all safety deceleration DC motors 21 to complete the parameter adaptive matching before processing.

[0030] 2. Descaling process: The fish with the parameters matched is put into the fish inlet 7 with the head facing forward and the belly facing down. The fish first passes through the high-speed rotating adaptive descaling device to remove the scales. At the same time, the scale rinsing nozzle 20 washes away the detached scales. Then the fish is transported to the adaptive feeding device.

[0031] 3. Fish gutting process: The fish is conveyed by the adaptive feeding device to the high-speed rotating gutting saw blade 26 of the fish gutting device. The saw blade 26 precisely cuts open the fish belly along the midline. The matching limiting device fits tightly against the fish back through the V-shaped opening of the fish back limiting plate 19 to ensure that the gutting position does not deviate and the depth is controllable, avoiding cutting the fish gallbladder. The V-shaped fish belly opening plate 12 behind the saw blade 26 opens the fish belly wall to prevent the fish belly from closing.

[0032] 4. Fish viscera cleaning process: The fish with its belly cut open continues to be conveyed forward. Under the control of the intelligent control module 9, the fish viscera cleaning device controls the safety deceleration DC motor 21 to drive the lifting mechanism. The lifting mechanism drives the fish viscera scraper 25 to extend to a length that matches the shape of the fish. As the fish is conveyed, the fish viscera are scraped off as a whole, realizing the separation of the viscera from the fish body. After the fish leaves the fish killing platform, the intelligent control module 9 controls the scraper to return to the initial position.

[0033] 5. Fish belly cleaning process: The fish with its internal organs removed is transported to the fish belly cleaning device via the adaptive output device. The intelligent control module 9 controls the cleaning brush 27 to work with the high-pressure water nozzle 13 to thoroughly scrub and rinse the inside of the fish belly, removing any remaining black film and dirt, and ensuring the fish is clean.

[0034] 6. Finished product discharge process: The cleaned fish are conveyed to the fish outlet 15 by the adaptive output device, completing the fully automated processing of a single fish. The processing time for a single fish is ≤30s.

[0035] 7. Visceral Resource Recycling Process: After the scraped fish viscera are filtered by the drainage device 1 to remove wastewater, the wastewater flows into the water tank 24. The filtered fish viscera slides into the mixing tank 23 of the viscera crushing and recycling device through the guide channel 17. The auxiliary material conveying device 16 simultaneously conveys feed auxiliary materials such as rice bran to the mixing tank 23. The intelligent control module 9 controls the safety deceleration DC motor 21 to drive the mixing blade 22 to rotate at high speed, crushing the fish viscera and mixing it evenly with the auxiliary materials. The resulting feed can be directly collected for aquaculture, realizing the resource utilization of waste.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any simple modifications, equivalent substitutions, improvements, etc., made within the technical concept of the present invention should be included within the protection scope of the present invention.
