Description

Technical Field

[0001] This invention relates to the field of fish processing technology, and in particular to a processing device for bighead carp. Background Technology

[0002] Current fish processing relies heavily on manual labor, which is not only labor-intensive, inefficient, and costly, but also prone to inconsistent quality due to varying worker skill levels. This can result in problems such as incomplete scaling, visceral residue, and damaged fish heads, seriously affecting product quality.

[0003] Furthermore, in existing fish processing equipment, the equipment for descaling and eviscerating is often set up separately, and the connection between each process is poor. It is still necessary to manually move and transfer the fish in each process, which cannot achieve automated fish processing, resulting in low processing efficiency and failing to meet the ever-increasing production demand.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The first direction, second direction, and third direction in this specification are labeled X, Y, and Z, respectively, in the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown, a preferred embodiment of the present invention provides a bighead carp processing device, which includes a descaling module 2, an internal organ cleaning module 3, a head and tail separation module 5, and a draining and storage module 6. The descaling module 2 includes a descaling mechanism 21 and a ventriloquism mechanism 22 disposed within a frame 1. The descaling mechanism 21 is used to abut against the fish body to remove fish scales, and the ventriloquism mechanism 22 is used to abut against the abdomen of the fish body to cut open the abdomen of the fish body.

[0027] The viscera cleaning module 3 includes a motion mechanism 31 and a viscera removal mechanism 32 disposed on the frame 1. The viscera removal mechanism 32 is configured to be inserted into the abdomen of the fish in a second direction to scrape out the fish's internal organs. The motion mechanism 31 is configured to drive the viscera removal mechanism 32 to move relative to the fish body to remove the internal organs.

[0028] The head and tail separation module 5 includes a separation mechanism 51, a support plate 52 and a blade 53 disposed on the frame 1. The support plate 52 is used to support the fish body after the internal organs have been removed. The support plate 52 and the separation mechanism 51 are disposed opposite to each other in the third direction. The separation mechanism 51 is configured to adjust the position of the blade 53 and drive the blade 53 closer to or further away from the fish body in the third direction to separate the fish head and the fish body. The drained storage module 6 is used to store the separated fish head and fish body separately.

[0029] Specifically, in this embodiment, a conveying module 4 is also provided. The conveying module 4 extends along the first direction and is disposed within the frame 1. The conveying module 4 is used to convey the fish body along the first direction, passing sequentially through the descaling mechanism 21, the evisceration mechanism 22, and the visceration mechanism 32. The fish body to be processed is placed in the conveying module 4. The conveying module 4 is driven by a motor and a pulley 41 to drive a belt (not shown in the figure), thereby moving the fish body along the first direction. The fish body first passes through the descaling mechanism 21 to remove the scales, and then passes through the evisceration mechanism 22 to cut open the abdomen, so as to facilitate the subsequent visceration and separation processes. After the evisceration process is completed, the fish body continues to be conveyed by the conveying module 4. Simultaneously, the motion mechanism 31 drives the evisceration mechanism 32 to move to the fish body. The evisceration mechanism 32 has entered the fish body through the opening made by the evisceration mechanism 22. As the conveying module 4 continues to convey the fish body along the first direction, the motion mechanism 31 also drives the evisceration mechanism 32 to move along the first direction and remove it from the fish body, thus facilitating the removal of the internal organs. After the internal organs are removed, the fish body is moved onto the support plate 52. The separation mechanism 51 moves the position of the cutting head 53 according to the position of the fish body obtained by the camera, aligning the cutting head 53 with the fish body. Then, the separation mechanism 51 drives the cutting head 53 to move along a third direction closer to the fish body, thereby achieving the separation of the fish head and body. In this embodiment, the modules for descaling, gutting, removing internal organs, and separating the head and body of the fish are integrated and set up in the same frame 1. The connection between the fish processing steps is smoother and more natural, the processing efficiency of the fish is higher, and the processing quality is more stable and reliable.

[0030] It is understood that, in some embodiments, the separation mechanism 51 can drive the blade 53 to move along a second and a third direction, thereby enabling the blade 53 to be more precisely aligned with the fish body. It should also be noted that by adjusting the movement sequence of the descaling mechanism 21, the evisceration mechanism 22, the movement mechanism 31, and the visceration mechanism 32, continuous automatic processing of the fish body can be achieved. This not only makes the structure more compact and reduces costs, but also further improves the processing efficiency and consistency of the fish body.

[0031] It should also be noted that the support plate 52 can be disposed on one side of the conveying module 4 along a first direction or along a second direction. When the support plate 52 is disposed on one side of the conveying module 4 along the first direction, the fish on the conveying module 4 tend to move in the first direction, naturally moving onto the support plate 52. Then, the cutter head 53 on the support plate 52 moves under the drive of the separation mechanism 51 and completes the separation. When the support plate 52 is disposed on one side of the conveying module 4 along the second direction, a pusher assembly 334 can be provided to push the fish from the conveyor belt of the conveying module 4 onto the support plate 52. Compared with the aforementioned embodiments, this is more compact in structure and has a higher space utilization rate. It is understood that in some embodiments, the height of the support plate 52 in the third direction is lower than the height of the conveying module 4 in the third direction, allowing the fish to fall naturally onto the support plate 52.

[0032] It should also be noted that in some other alternative embodiments, the motion mechanism 31 can also drive the viscera removal mechanism 32 to rotate. By rotating the viscera removal mechanism 32, the internal organs of the fish can also be removed. In this embodiment, the fish stops on the conveying module 4, and then the viscera removal mechanism 32 is inserted into the fish. The viscera removal mechanism 32 is then driven to rotate to remove the internal organs of the fish and collect them in the viscera storage chamber 34. Then the conveying module 4 continues to convey the fish to the support plate 52 in the first direction, or pushes the fish to the support plate 52 in the second direction through the push plate 335.

[0033] like Figure 3 and Figure 4 As shown, in some embodiments, the descaling mechanism 21 includes a movable frame 211, a first descaling component 212, and a second descaling component 213. The movable frame 211 is configured to move relative to the frame 1 in a third direction. The first descaling component 212 and the second descaling component 213 are respectively disposed on the frame 1 and the movable frame 211, and the first descaling component 212 and the second descaling component 213 are disposed opposite to each other in a third direction to abut against the two sides of the fish body respectively.

[0034] Specifically, when descaling fish, traditional descaling mechanisms 21 often fail to stably fit fish of varying sizes, resulting in poor descaling quality and a high rate of scale residue. In this embodiment, a movable frame 211 is additionally provided. This movable frame 211 is connected to the frame 1 via a scissor mechanism, slide rail structure, or telescopic rod connection structure 214. This allows the movable frame 211 to move up and down along a third direction under the pressure of the fish, enabling the second descaling component 213 to more stably contact the fish, thus adapting to different sizes and achieving better and more stable descaling quality. In a specific embodiment, a belt conveyor mechanism 215 is also provided on the movable frame 211 corresponding to the conveying module 4. Both the belt conveyor mechanism 215 and the belt of the conveying module 4 are equipped with a brush layer or sandpaper layer. The two belts contact the sides of the fish to remove scales.

[0035] Furthermore, the first descaling component 212 also includes a first descaling part 2121 and a second descaling part 2122, and the second descaling component 213 also includes a third descaling part 2131 and a fourth descaling part 2132. The first descaling part 2121 and the second descaling part 2122 are arranged opposite each other along a second direction, and the third descaling part 2131 and the second descaling part 2122 are also arranged opposite each other along a second direction. The first descaling part 2121 and the third descaling part 2131 respectively abut against the upper and lower sides of the fish's abdomen, while the second descaling part 2122 and the fourth descaling part 2132 respectively abut against the upper and lower sides of the fish's back. This allows for targeted treatment of the scales on the fish's abdomen and back, solving the technical problem of high scale residue caused by blind spots in belt descaling. Each descaling part also has a brush layer or sandpaper layer on the side facing the fish, thereby removing scales by grinding or scraping. In one specific embodiment, each descaling section has an arc-shaped structure, with its outer arc surface conforming to the fish body, thus enabling it to better fit fish of different sizes.

[0036] It should also be noted that, due to the varying sizes of fish, the thickness can be accommodated by the up-and-down movement of the movable frame 1 along a third direction. In the width direction, to allow each descaling section to adapt to fish of different sizes, this embodiment includes support slides 223 extending along a second direction on both the frame 1 and the movable frame 211. Each descaling section is slidably mounted on the support slides 223, and a return spring 224 is provided between each descaling section and its corresponding movable frame 211 or frame 1. This spring drives the first descaling section 2121 and the second descaling section 2122 to move towards each other and approach each other along the second direction, as well as the third descaling section 2131 and the fourth descaling section 2132. When facing large fish, the descaling sections can also be compressed and moved away from each other. During this process, the contact between the descaling sections and the fish becomes more stable and reliable, improving the descaling quality. It is understandable that it is only necessary for the first descaling part 2121 and the second descaling part 2122 to slide along the second direction to the frame 1, and for the third descaling part 2131 and the fourth descaling part 2132 to slide along the second direction to the movable frame 211. As mentioned above, a support slide rod 223 can be used, or a slide rail, guide rail, or telescopic rod can be used.

[0037] In some embodiments, the laparotomy mechanism 22 includes a laparotomy knife 221 and a first motor 222, the first motor 222 being fixed to the frame 1, the laparotomy knife 221 being connected to the first motor 222 in a drive connection, and the first motor 222 being configured to drive the laparotomy knife 221 to rotate in order to cut open the fish belly.

[0038] Specifically, after the scaling of the fish is completed, the conveying module 4 continues to convey the fish along the first direction to the evisceration mechanism 22. The evisceration knife 221 and the first motor 222 are both located on one side of the conveying module 4 along the second direction, with the evisceration knife 221 positioned opposite the fish's abdomen. The first motor 222 drives the evisceration knife 221 to move relative to the fish, thus bringing it into contact with the fish to complete the evisceration. In one specific embodiment, the evisceration knife 221 has a disc-shaped blade, and the first motor 222 drives it to rotate around its central axis, allowing it to rotate relative to the fish and thus more stably and quickly eviscerate the fish's abdomen. In other alternative embodiments, the evisceration knife 221 has a common strip-shaped structure with its tip aligned with the fish's abdomen, and the first motor 222 drives it to move along the second direction to adjust the position of the evisceration knife, thereby adapting to the evisceration needs of fish of different sizes.

[0039] It should also be noted that in this embodiment, the evisceration mechanism 22 further includes a fish-blocking block 225, which is positioned along the first direction on the side of the evisceration knife 221 away from the descaling mechanism 21. When the fish moves to the evisceration mechanism 22, the fish-blocking block 225 moves along the second direction above the conveying module 4, thereby temporarily preventing the fish from continuing to move along the first direction. At the same time, the brush layer on the conveyor belt of the conveying module 4 further removes the scales from the fish, and the evisceration knife 221 can also better cut into the fish by rotating. Subsequently, the fish-blocking block 225 moves away, the fish continues to move along the first direction, and the evisceration knife 221 can also cut open the fish's belly. Furthermore, in this embodiment, the fish-blocking block 225 and the ventriloquist knife 221 are linked together. The frame 1 is provided with a first guide rail 226 extending along the second direction corresponding to the fish-blocking block 225. The fish-blocking block 225 is slidably connected to the frame 1 through the first guide rail 226. A first rack 227 is provided on the side of the fish-blocking block 225. The first motor 222 is connected to a first gear 228. The first gear 228 meshes with the first rack 227. The first motor 222 can drive the fish-blocking block 225 to reciprocate along the second direction through the first gear 228 and the first rack 227.

[0040] like Figure 5 and Figure 6 As shown, in some embodiments, the motion mechanism 31 includes a second motor 311 and a swing link 312. The second motor 311 is fixed to the frame 1, the first end of the swing link 312 is rotatably connected to the frame 1, and the second end of the swing link 312 is slidably connected to the viscera removal mechanism 32. The second motor 311 is drively connected to the swing link 312, and the second motor 311 is configured to drive the swing link 312 to swing back and forth about the rotation axis of its first end to drive the viscera removal mechanism 32 to move back and forth in a first direction.

[0041] Specifically, in the timing control, as the fish gradually moves away from the evisceration knife 221 under the drive of the conveying module 4, the second motor 311 also drives the swing linkage 312 to swing, thereby driving the evisceration mechanism 32 to gradually approach the evisceration knife 221 along the first direction until the evisceration mechanism 32 contacts the fish and inserts into the fish. Subsequently, the fish continues to move along the first direction under the drive of the conveying module 4, and the evisceration mechanism 32 also moves along the first direction along with the fish under the drive of the swing linkage 312. In a specific embodiment, the moving speed of the evisceration mechanism 32 is faster than the moving speed of the fish, so that the evisceration mechanism 32 can better scrape the internal organs out of the fish to complete the removal of the fish's internal organs. In one specific embodiment, the frame 1 is also provided with an internal organ storage chamber 34, which is located on one side of the conveying module 4. After the internal organ removal mechanism 32 removes the internal organs from the fish body, the internal organ removal mechanism 32 will continue to move along the first direction to the top of the internal organ storage chamber 34 under the drive of the swing linkage 312, so that the internal organs fall into the internal organ storage chamber 34, thereby realizing the collection and storage of internal organs.

[0042] Furthermore, in this embodiment, the swing linkage 312 has a first groove 3121 and a second groove 3122 along its length. The output end of the second motor 311 is connected to the first connecting rod 313, and the other end of the first connecting rod 313 is provided with a first slider, which is disposed in the first groove 3121. The viscera removal mechanism 32 is provided with a second slider, which is disposed in the second groove 3122. When the second motor 311 drives the first connecting rod 313 to rotate, the first connecting rod 313 drives the first slider to slide in the first groove 3121, thereby driving the swing linkage 312 to swing back and forth, thereby driving the viscera removal mechanism 32 to move. The second slider and the second groove 3122 are provided to cooperate with the sliding connection between the viscera removal mechanism 32 and the frame 1, so that the viscera removal mechanism 32 can reciprocate relative to the frame 1 in the first direction.

[0043] like Figure 7 As shown, in some embodiments, the viscera removal mechanism 32 includes a servo base 321, a scraping spoon 322 and a third motor 323. The servo base 321 is slidably connected to the frame 1 along a first direction and slidably connected to the swing link 312. The third motor 323 is fixed to the servo base 321, and the scraping spoon 322 is slidably connected to the servo base 321 along a second direction. The third motor 323 is connected to a cam 324, which is configured to abut against the scraping spoon 322 and drive the scraping spoon 322 to move in a second direction to approach or move away from the belly of the fish.

[0044] Specifically, the frame 1 is provided with a second guide rail 326 extending along the first direction, and the servo base 321 is slidably connected to the frame 1 through the second guide rail 326. The servo base 321 is also provided with a second slider, which, in conjunction with the swing connection, enables the servo base 321 to reciprocate along the first direction. At the same time, the servo base 321 is also provided with a third guide rail 327 extending along the second direction, and a scraping spoon 322 is slidably connected to the third guide rail 327, which can move along the second direction. In actual operation, an elastic reset element (not shown, but can be a spring or rubber band) is provided between the scraping spoon 322 and the servo base 321. The rotation of the third motor 323 drives the cam 324 to rotate. Due to the structural features of the cam 324, the scraping spoon 322 can be pushed towards the fish body by the cam 324 so that the scraping spoon 322 can be inserted into the fish body. Then, in conjunction with the movement of the servo base 321 in the first direction, the internal organs of the fish body can be scraped off. When the cam 324 rotates one revolution or the third motor 323 reverses, the scraping spoon 322 will move away from the fish body under the action of the elastic reset element, thereby removing the internal organs from the fish body and transporting the internal organs to the top of the internal organ storage compartment 34. This improves the processing quality of the internal organs, avoids the residue of internal organs, and also prevents the internal organs from falling onto the conveying module 4, causing pollution or affecting subsequent processing.

[0045] It should also be noted that in the action timing control, the scraping spoon 322 needs to be controlled to extend into the abdomen of the fish only after the servo base 321 moves to the tail of the fish. Then, the scraping spoon 322 is kept inside the fish. By utilizing the speed difference between the fish and the scraping spoon 322 in the first direction, the scraping spoon 322 can stably scrape the fish's internal organs. When the scraping spoon 322 moves to the lower jaw of the fish, the side of the cam 324 with the smaller radius can be controlled to abut against the fish, so that the scraping spoon 322, which is full of internal organs, can move away from the fish under the action of the elastic reset member, thereby removing the internal organs from the fish.

[0046] In some embodiments, the viscera removal mechanism 32 further includes flaring components 325 symmetrically arranged on both sides of the servo base 321 along a first direction. The flaring components 325 include a rotating wheel 3251, a first support rod 3252 and a second support rod 3253. The first support rod 3252 and the second support rod 3253 are arranged opposite each other along a third direction. The first support rod 3252 is fixedly connected to the servo base 321. The second support rod 3253 is driven by the rotating wheel 3251 to the third motor 323. The rotating wheel 3251 is configured to reciprocate to drive the second support rod 3253 to reciprocate towards and away from the first support rod 3252 along a third direction.

[0047] Specifically, the scraping spoon 322 has a certain height in the third direction to more comprehensively scrape the fish's internal organs. To ensure the scraping spoon 322 can stably enter and exit the fish and improve the scraping quality, the opening in the fish's abdomen needs to be pre-opened. Therefore, this embodiment provides two flaring components 325 spaced apart along the first direction. The second support rod 3253 of the flaring component 325 can move relative to the first support rod 3252 in the third direction, thereby opening the opening in the fish's abdomen. In a secondary embodiment, the flaring components 325 can be driven by a separate motor. However, considering factors such as cost, space utilization, and timing control, in this embodiment, both flaring components 325 are connected to the third motor 323. In this embodiment, the third motor 323 drives the rotating wheel 3251 to rotate. A second connecting rod 3254 is fixedly installed on one side of the rotating wheel 3251, and the other end of the second connecting rod 3254 is rotatably connected to the second support rod 3253. A third connecting rod 3255 is also provided between the second support rod 3253 and the first support rod 3252. The two ends of the third connecting rod 3255 are rotatably connected to the first support rod 3252 and the second support rod 3253, respectively. When the third motor 323 drives the rotating wheel 3251 to rotate, the rotating wheel 3251 can drive the second support rod 3253 to move in a third direction and a second direction via the second connecting rod 3254. This increases the distance between the second support rod 3253 and the first support rod 3252. The third connecting rod 3255 keeps the second support rod 3253 and the third support rod flush, ensuring that the fish belly can be stably opened.

[0048] like Figure 8 and Figure 9 As shown, in some embodiments, the separation mechanism 51 includes a lifting assembly 511 and a translation assembly 512. The translation assembly 512 includes a fourth motor 5121 and a tool holder mounting plate 5122. The fourth motor 5121 is driven to the tool holder mounting plate 5122. The lifting assembly 511 is fixed on the tool holder mounting plate 5122. The fourth motor 5121 is configured to drive the tool holder mounting plate 5122 to reciprocate along a first direction. The lifting assembly 511 includes a fifth motor 5111, a lifting gear 5112, and a lifting rack 5113. The fifth motor 5111 is fixed to the tool holder mounting plate 5122. The fifth motor 5111 is connected to the lifting rack 5113 through the lifting gear 5112. The lifting rack 5113 extends along a third direction and is slidably connected to the tool holder mounting plate 5122. A cutter head 53 is fixedly provided at the end of the lifting rack 5113.

[0049] Specifically, after the internal organs of the fish are removed, some fish, such as bighead carp, still need to have their heads and bodies separated for subsequent work. In this embodiment, a lifting assembly 511 and a translation assembly 512 are provided. The bottom of the lifting assembly 511 is fixedly equipped with a blade 53. The lifting assembly 511 can adjust the position of the blade 53 in a third-degree upward direction, bringing the blade 53 closer to the fish body to achieve separation of the head and body. The translation assembly 512 can translate and adjust the position of the lifting assembly 511 and the blade 53 in a first direction and a second direction, so that the blade 53 can be more accurately aligned with the boundary between the head and body, and can better adapt to the separation needs of fish of the same size.

[0050] In some embodiments, the lifting assembly 511 may be a vertically arranged linear module, or it may be equipped with a linear drive structure such as pneumatic or hydraulic. In this embodiment, a gear rack structure with lower cost and simpler structure is adopted. The fifth motor 5111 drives the lifting gear 5112 to rotate, thereby driving the lifting rack 5113 to move up and down along a third direction, thereby adjusting the position of the cutter head 53 located at the end of the lifting rack 5113.

[0051] Furthermore, in some embodiments, the translation component 512 can employ two stacked linear modules to drive the lifting component 511 to move along the first and second directions respectively, thereby enabling more precise adjustment of the cutter head 53's position. Due to differences in fish size, the position of the fish moving from the conveying module 4 to the support plate 52 will vary, primarily in the first direction. Considering cost and structural simplification, it is sufficient to control the lifting component 511 to move along the first direction to adjust the cutter head 53's position. Errors in the second direction can be addressed by increasing the size of the cutter head 53, ensuring it covers the separation requirements of fish of all sizes. Therefore, in a preferred embodiment, the translation component 512 only needs a fourth motor 5121 to control the cutter holder mounting plate 5122 to move along the first direction. In one specific embodiment, the translation component 512 also includes a tool holder base plate 5123. The frame 1 is provided with a fourth guide rail 5124 extending along the first direction corresponding to the tool holder base plate 5123. The tool holder base plate 5123 is slidably connected to the frame 1 through the fourth guide rail 5124. The tool holder mounting plate 5122 is rotatably connected to the tool holder base plate 5123. The fourth motor 5121 is driven by a fourth connecting rod. The other end of the fourth connecting rod is rotatably connected to the tool holder mounting plate 5122. The fourth motor 5121 drives the fourth connecting rod to rotate, thereby driving the tool holder mounting plate 5122 to swing. Its cooperation with the tool holder base plate 5123 can control the lifting component 511 to move along the first direction. It only uses a motor and rod structure. Compared with the precision linear module structure, it has lower cost, higher stability, and is more suitable for the humid environment of fish processing.

[0052] It is understandable that the head and tail separation module 5 is also equipped with a visual positioning mechanism (not shown in the figure). This visual positioning mechanism includes an industrial camera and a supplementary light, etc. The industrial camera takes pictures of the fish body, and then the control chip identifies the boundary between the fish head and the fish body. The control chip then controls the translation component 512 to move the cutter head 53 to the boundary between the fish head and the fish body, which can further improve the accuracy of fish body separation.

[0053] In some embodiments, the draining storage module 6 includes a first plate 61 and a second plate 62. Both the first plate 61 and the second plate 62 are disposed below the support plate 52 along a third direction. The first plate 61 is used to support the fish body, and the second plate 62 is used to support the fish head. The bearing plate 52 is slidably connected to the frame 1 along the second direction.

[0054] Specifically, after the fish head and body are separated, they need to be transported and stored separately to facilitate subsequent work. Therefore, in this embodiment, a first plate 61 and a second plate 62 are provided below the support plate 52, with a partition between them. The fish head and body can move onto the second plate 62 and the first plate 61 respectively, and then be transported and stored separately. In other embodiments, a mechanical structure can be used to push the fish head and body on the support plate 52 along a second direction, causing them to fall onto the second plate 62 and the first plate 61 respectively, thus achieving separate transport of the fish head and body. In a preferred embodiment, considering space utilization and structural simplification, a seventh motor (not shown) is fixedly mounted on the frame 1. The seventh motor is driven by a second gear 521, and a second rack 522 extending in a second direction is provided at the bottom of the support plate 52. The second rack 522 meshes with the second gear 521, so that the seventh motor can drive the support plate 52 to move in the second direction. During the movement of the support plate 52 in the second direction, the fish head and body will move relative to the support plate 52 due to their own weight, and eventually land on the second plate 62 and the first plate 61, respectively. Of course, it is understood that in some other embodiments, plates can also be provided on the frame 1 to block the fish head and body, preventing them from moving with the support plate 52, thereby ensuring that the fish head and body can land stably on their respective plates. It should also be noted that in some embodiments, the first plate 61 and the second plate 62 are both inclined, and the first plate 62 and the second plate 61 are both provided with an array of holes. The inclined plates allow the fish head and body to slide down naturally under the action of gravity, while the holes facilitate the penetration of blood and water, so as to drain the fish head and body and prevent blood and water from being transferred to the next process.

[0055] like Figure 5 and Figure 6 As shown, in some embodiments, the visceral cleaning module 3 further includes a limiting mechanism 33, which includes a baffle 331, a sixth motor 332 and a limiting component 333. The baffle 331 includes a first state and a second state. The sixth motor 332 is configured to connect to the baffle 331 through the limiting component 333 to control the baffle 331 to switch between the first state and the second state. In the first state, the baffle 331 is configured to abut against the side of the fish body away from the evisceration mechanism 32 to limit the fish body; in the second state, the baffle 331 is located above the fish body in a third direction to release the restriction on the fish body.

[0056] Specifically, during the evisceration process, the conveying module 4 continues to convey the fish along the first direction, while the scraping spoon 322 is inserted into the fish's abdomen along the second direction to scrape out the evisceration. During this process, the fish is subjected to forces from multiple directions, making its position and posture prone to change, which can affect the subsequent separation process. Therefore, in this embodiment, a limiting mechanism 33 is provided. The baffle 331 of this limiting mechanism 33, in its first state, abuts against the back of the fish, thus preventing changes in the fish's position and facilitating subsequent separation. After the evisceration process is completed, the baffle 331 switches to the second state, where it is positioned above the fish, allowing the fish to be smoothly moved onto the support plate 52. In one specific embodiment, the limiting component 333 includes a fifth link 3331, a sixth link 3332, and a seventh link 3333. One end of the fifth link 3331 is connected to the sixth motor 332, and the other end of the fifth link 3331 is rotatably connected to the sixth link 3332. The other end of the sixth link 3332 is fixed to a baffle 331. The middle of the sixth link 3332 is rotatably connected to the seventh link 3333, and the other end of the seventh link 3333 is rotatably connected to the frame 1. Thus, the sixth motor 332 can switch the position of the baffle 331 between a first state and a second state through the transmission between the three links. In one specific embodiment, two sixth motors 332, fifth link 3331, sixth link 3332, and seventh link 3333 are symmetrically arranged along the first direction, and the two sixth links 3332 are respectively connected to the two ends of the baffle 331, thereby making the movement of the baffle 331 more stable. It should also be noted that in actual use, the rotation speed of the sixth motor 332 needs to be controlled to adjust the timing coordination between the baffle 331 and the viscera removal mechanism 32.

[0057] In some embodiments, the sixth motor 332 is driven to a pusher assembly 334, the pusher assembly 334 is connected to a pusher 335, the pusher 335 is slidably connected to the frame 1, and the sixth motor 332 is configured to drive the pusher 335 to reciprocate along a second direction via the pusher assembly 334 to push the fish body onto the support plate 52.

[0058] Specifically, in this embodiment, the support plate 52 is positioned below the conveying module 4 along a third direction. After the fish's internal organs are removed, the baffle 331 also moves to the second state. At this time, the sixth motor 332 drives the pusher plate 335 to move along the second direction through the pusher plate assembly 334. The fish on the conveying module 4 is pushed along the second direction until it falls onto the support plate 52, after which the subsequent separation work can be carried out. In a specific embodiment, the pusher plate assembly 334 includes an eighth link 3341 and a ninth link 3342. The sixth motor 332 is connected to one end of the eighth link 3341 through two gears to drive the eighth link 3341 to rotate around one end. The other end of the eighth link 3341 is rotatably connected to the ninth link 3342, and the other end of the ninth link 3342 is rotatably connected to the baffle 331. Thus, the sixth motor 332 can drive the pusher plate 335 to move along the second direction through the eighth link 3341 and the ninth link 3342. It should be noted that when the sixth motor 332 drives the baffle 331 to move from the first state to the second state, the sixth motor 332 also synchronously drives the baffle 331 to move along the second direction to push the fish body onto the support plate 52. By controlling the timing of their actions, coordination can be achieved. It is understood that, in a secondary embodiment, the pusher 335 can also be driven independently by a linear module or a motor.

[0059] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
