Description

Technical Field

[0001] This utility model belongs to the field of fishery machinery technology, specifically relating to an integrated continuous fish-killing machine that does not require screening. Background Technology

[0002] A multi-functional integrated fish-killing machine is a processing machine that uses fish as its target. Currently, fish processing on the market involves three steps: descaling, gutting, and removing internal organs. The quality of integrated fish-killing machines on the market varies greatly, but none can simultaneously perform these three functions, meaning they cannot operate sequentially and continuously. This increases processing time, costs, and energy consumption. Most importantly, fish scales are located on the back and sides of the fish, and current fish-killing machines cannot handle these areas in one operation. While some machines may have a scale-removing function, it's difficult to guarantee comprehensive scale removal. For example, the State Intellectual Property Office has disclosed a multi-functional fish-killing machine, publication number CN112913902A, which discloses a package... The fish-killing machine includes a box body, a conveying mechanism, and a gutting mechanism. The bottom of the inner wall of the box body is sloped to facilitate the discharge of sewage, viscera, and scales. The conveying mechanism can clean the scales while conveying the fish, and the gutting mechanism can clean the viscera inside the fish. Although it can remove scales and gut the fish, it can only remove scales from the sides of the fish, making its functionality limited. For example, the State Patent Office has disclosed a new type of fish-killing machine, publication number CN211983560U, which only has a scale removal function and cannot perform functions such as opening the back or removing viscera. Furthermore, when killing fish in batches, it is necessary to select fish of suitable size for processing. Selecting fish by size also helps improve the efficiency of fish-killing. Small fish and large fish require different methods and tools for processing and slaughtering. For example, small fish may be easier to process quickly, while large fish require more time and effort to kill and clean. Due to the large number of fish being killed in batches, current fish-killing tools are limited and mostly handheld. Equipment for killing fish in batches is also limited in function, requiring initial screening to produce fish of appropriate sizes, and failing to utilize the structural characteristics of the fish itself to achieve continuous operation.

[0047] Specific implementation method one: Combining Figures 1 to 14The following is a description of this specific embodiment, which adopts the following technical solution: It includes a fish inlet 1, a first continuous spring descaling device 2, a second continuous spring descaling device 3, a first push gear mechanism 4, an upper and lower descaling mechanism 5, a second push gear mechanism 6, a serrated blade assembly 7, a separation device 8, a high-pressure water gun 9, a conveying and pressing mechanism 10, a separation fork mechanism 11, an internal organ collection box 12, a fish body collection box 13, a drive system 14, and a main frame 15.

The first continuous spring descaling device 2 and the second continuous spring descaling device 3 are respectively arranged on the right side of the fish inlet 1. The spring descaling device 3, the first continuous spring descaling device 2, and the second continuous spring descaling device 3 can descale both sides of the fish body. Simultaneously, the first continuous spring descaling device 2 and the second continuous spring descaling device 3 employ different rotation speeds to improve descaling efficiency. Both the first continuous spring descaling device 2 and the second continuous spring descaling device 3 are mounted on the main frame 15. The bottom of the first continuous spring descaling device 2 and the second continuous spring descaling device 3 is connected to the drive system 14, which drives the first continuous spring descaling device 2 and the second continuous spring descaling device 3. The rear side of the second continuous spring descaling device 3 is respectively equipped with a first push gear mechanism 4 and a second push gear mechanism 6. A scale removal mechanism 5 is provided between the first push gear mechanism 4 and the second push gear mechanism 6. The scale removal mechanism 5 can remove the scales from the upper and lower parts of the fish body. The first push gear mechanism 4 and the second push gear mechanism 6 are fixedly installed on the main frame 15. The lower ends of the first push gear mechanism 4 and the second push gear mechanism 6 are connected to the drive system 14. The first push gear mechanism 4 and the second push gear mechanism 6 can push the fish body. A serrated blade group 7 is provided on the right side of the second push gear mechanism 6. The serrated blade group 7 is used to open the back of the fish. A separation device 8 is provided on the rear side of the serrated blade group 7. The separation device 8 is fixedly installed on the main frame 15. The separation device 8 can unfold the fish body after opening the back. A conveying and pressing mechanism 10 is provided on the right side of the separation device 8. The unfolded fish body enters the conveying and pressing mechanism 10. A high-pressure water gun 9 is provided on the upper side of the conveying and pressing mechanism 10. The pressed fish body is cleaned by the high-pressure water gun 9, so that the internal organs are separated from the fish body. The high-pressure water gun 9 and the conveying and pressing mechanism 10 are both fixedly installed on the main frame 15. A separation fork mechanism 11 is provided at the end of the conveying and pressing mechanism 10. An internal organ collection box 12 is provided at the bottom of the separation fork mechanism 11. A fish body collection box 13 is provided on the left side of the internal organ collection box 12. The separation fork mechanism 11 separates the internal organs and the fish body into the internal organ collection box 12 and the fish body collection box 13, respectively.

[0048] The working principle of this specific implementation method is as follows: The fish is placed into the fish inlet 1. The fish enters the machine with its back facing up and its belly facing down. The fish inlet 1 can hold the fish body tightly. At the same time, the fish enters the first continuous spring descaling device 2 and the second continuous spring descaling device 3 to scrape off the scales on the side of the fish body. Then, the fish body is pushed into the upper and lower descaling mechanism 5 by the first push gear mechanism 4. The upper and lower descaling mechanism 5 removes the scales on the upper and lower parts of the fish body. After descaling, it is pushed into the serrated blade group 7 by the second push gear mechanism 6. The serrated blade group 7 opens the back of the fish body. The opened back of the fish body is spread out by the separation device 8 to achieve complete back opening. The opened back of the fish body is pressed and transported by the conveying and pressing conveying mechanism 10. It is cleaned by the high-pressure water gun 9, so that the internal organs are separated from the fish body. The internal organs enter the internal organ collection box 12 from the filter groove on the separation fork mechanism 11. The fish body slides into the fish body collection box 13 from the upper surface of the separation fork mechanism 11. At this time, the descaling, back opening, separation and collection of the fish body are completed.

[0049] Specific Implementation Method Two: Combining Figure 4 The illustration shows this specific embodiment, which is a further limitation of Specific Embodiment 1. In this specific embodiment, the fish inlet 1 can accommodate fish of different sizes. The specific technical solution adopted is as follows: The fish inlet 1 includes a lower V-shaped iron plate 101, a plate support rod 102, a spring 103, a top support rod 104, an upper V-shaped plate 105, and a lower plate bracket 106; the lower V-shaped iron plate 101 is fixedly installed on the lower plate bracket 106, and the lower plate bracket 106 is fixedly connected to the main frame 15, allowing the fish to adhere to the lower V-shaped iron plate 105. On the upper surface of 01, an upper V-shaped plate 105 is provided on the upper side of the lower V-shaped iron plate 101. The two ends of the upper V-shaped plate 105 are fixedly connected to the lower ends of the two plate support rods 102 respectively. A spring 103 is sleeved on the outside of the plate support rod 102. The upper V-shaped plate 105 can move on the plate support rod 102. When the fish enters, the spring 103 can drive the upper V-shaped plate 105 to descend and press the fish tightly. The upper ends of the two plate support rods 102 are connected to the bottom of the top support rod 104. The top support rod 104 is installed on the main frame 15.

[0050] In this specific embodiment, when a fish enters the fish inlet 1, the fish initially enters with its back facing upward and its belly facing downward, with its belly against the lower V-shaped iron plate 101. When the fish is too large, the upper part of the fish will push the upper V-shaped plate 105 upward, and the spring 103 will be in a compressed state. At this time, the upper V-shaped plate 105 and the lower V-shaped iron plate 101 can clamp the fish, and the fish inlet 1 can be adjusted to a size suitable for the fish to enter, making it convenient for the fish to enter.

[0051] Specific implementation method three: Combining Figure 5The following describes a specific embodiment, which is a further limitation of embodiment one or two. In this specific embodiment, the first continuous spring descaling device 2 and the second continuous spring descaling device 3 can achieve descaling of the sides of the fish. The specific technical solution adopted is as follows: The first continuous spring descaling device 2 and the second continuous spring descaling device 3 have the same structure, both including a descaling slide 201, an upper support shaft 202, a second spring 203, a spring with a descaling slide 204, and a lower support shaft 205; several descaling slides 201 are sleeved on the two spiral springs 203, and springs with descaling slides 204 are arranged between the several descaling slides 201. The upper end of the second spring 203 is connected to the upper support shaft 202, and the lower end of the second spring 203 is fixedly installed with the lower support shaft 205. The descaling of the fish is achieved by the descaling slides 201 and the springs with descaling slides 204.

[0052] In this specific embodiment, the installation is achieved through the lower support shaft 205, which can drive the second spring 203 to rotate. When the second spring 203 rotates, its descaling slide 201 and the spring with the descaling slide 204 remove the scales from the side of the fish body.

[0053] Specific implementation method four: Combination Figure 6 The illustration shows this specific embodiment, which is a further limitation of embodiment one, two, or three. In this specific embodiment, the first pushing gear mechanism 4 and the second pushing gear mechanism 6 realize the pushing of the fish body. The specific technical solution is as follows: The first pushing gear mechanism 4 and the second pushing gear mechanism 6 have the same structure, each including a spring 401, a saw gear 402, an upper slider 403, a connecting shaft 404, a lower slider 405, a universal joint 406, and a movable shaft 407; the inner sides of several movable shafts 407 are respectively movably connected to the two upper sliders 403 and two... Inside the movable hole on the side wall of the lower slider 405, the two upper sliders 403 and the two lower sliders 405 can move on the movable shaft 407 to facilitate the entry of the fish. The outer ends of several movable shafts 407 are fixedly installed on the main frame 15. Springs 401 are sleeved on the outer side of the movable shafts 407. Connecting shafts 404 are fixedly installed between the two upper sliders 403 and the two lower sliders 405. Several sawing gears 402 are evenly installed on the two connecting shafts 404. The sawing gears 402 can clamp the fish. A universal joint 406 is fixedly installed at the bottom of the lower slider 405.

[0054] In this specific embodiment, the first push gear mechanism 4 and the second push gear mechanism 6 are driven by the drive system 14. The universal joint 406 is used to drive the upper slider 403 and the lower slider 405 when they slide. When the fish enters, the two sets of saw gears 402 are under force, and the upper slider 403 and the lower slider 405 slide outward on the movable shaft 407. The spring 401 is in a compressed state, which facilitates the clamping of the fish and enables the fish to be driven forward.

[0055] Specific Implementation Method Five: Combining Figure 7 The illustration shows this specific embodiment, which is a further limitation of embodiment one, two, three, or four. In this specific embodiment, the upper and lower scale removal mechanism 5 removes the upper and lower scales of the fish body, and the specific technical solution is as follows: The upper and lower scale removal mechanism 5 includes a lower slider 501, an upper slider 502, an upper conical scaler 503, a spring 504, a lower conical scaler 505, and a movable shaft 506; the lower slider 501 and the upper slider 502 are movably connected to both movable shafts 506, and the lower slider 501 and the upper slider 502 can move on the movable shafts 506. Springs 504 are sleeved on both the upper and lower sides of the movable shafts 506. Spring 4 504 can realize the reset of lower slider 2 501 and upper slider 2 502. The two ends of the rotating shaft of the lower conical descaling device 505 are respectively installed in the rotating holes between the two lower sliders 2 501. The two ends of the rotating shaft of the upper conical descaling device 503 are respectively installed in the rotating holes between the two upper sliders 2 502. The upper conical descaling device 503 and the lower conical descaling device 505 are driven to rotate by a motor. The upper and lower fish scales are removed by the upper and lower conical descaling devices 503 and 505. The upper conical descaling device 503 and the lower conical descaling device 505 adopt a symmetrical conical design. The two conical bodies are connected by the same shaft with their tips facing each other. The surface of the conical bodies has fine scraping texture or protrusions.

[0056] In this specific embodiment, when removing scales from the upper and lower parts of the fish, the upper conical scaler 503 and the lower conical scaler 505 are driven by a motor. The fine scraping texture or protrusions on the surface of the upper conical scaler 503 and the lower conical scaler 505 can remove scales from the upper and lower parts of the fish. At the same time, when the fish head enters between the upper conical scaler 503 and the lower conical scaler 505, the spring 4 504 is compressed, and the lower slider 2 501 and the upper slider 2 502 move up and down on the movable shaft 2 506. This can be used for fish of different sizes. At the same time, the spring 4 504 can make the upper conical scaler 503 and the lower conical scaler 505 fit the fish body, which is convenient for quick scale removal.

The serrated blade 702 is fixedly installed on the rotating shaft 701. The rotating shaft 701 is installed in the mounting hole of the main frame 15 through a bearing. One end of the rotating shaft 701 is connected to the shaft of the cutting motor 703. The cutting motor 703 is fixedly installed on the main frame 15. The cutting motor 703 can drive the rotating shaft 701 to rotate, so that the serrated blade 702 can open the back of the fish.
