Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to an automated production line for eels. Background Technology

[0002] Eels, a popular aquatic ingredient, are beloved by consumers for their tender flesh and delicious flavor. However, the process of gutting and processing eels has long been a challenge for the entire industry. Traditional methods of gutting eels rely primarily on manual labor, which is not only labor-intensive and inefficient but also poses certain safety hazards. Furthermore, the smooth and sticky mucus covering the eel's body makes it difficult to grip firmly during gutting, increasing the difficulty and post-gutting cleaning work.

[0003] With the rapid development of science and technology, automation technology has been widely applied in various industries, significantly improving production efficiency and quality. However, in the field of eel gutting and processing, the application of automation technology is still relatively lagging behind. Although there are some automated equipment related to eel processing on the market, they are often single-function, making it difficult to achieve full automation of the gutting and processing process. Moreover, they have high requirements for the size and shape of the eels, failing to meet the diverse and large-scale production needs. Summary of the Invention

[0004] The purpose of this invention is to provide an automated production line for eels, which has the advantages of high efficiency and good cleaning effect.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automated production line for eels, wherein a vibration grading device, an automatic sorting device and an automatic gutting device are arranged sequentially in the horizontal direction;

[0006] The vibration grading device includes a fixed frame, on which a sorting box is fixedly connected by a compression spring. The discharge end of the sorting box is provided with a plurality of feeding channels from top to bottom, and the plurality of feeding channels are arranged alternately. The feeding channels are connected to the automatic sorting device.

[0007] The automatic alignment device includes a discharge channel disposed at the discharge end of the feeding channel. The discharge channel is provided with several partitions, which divide the discharge channel into several diversion channels that gradually decrease in size along the discharge direction.

[0008] The automatic dissection device includes a support frame, and a dissection box is slidably connected to the support frame in the vertical direction. An automatic dissection machine is installed inside the dissection box. The automatic dissection machine is an automatic back opening machine or an automatic belly opening machine.

[0009] By adopting the above technical solution, eels enter from one end of the vibration grading device. After vibration grading, eels of different grades fall from different feeding channels to their corresponding discharge channels, keeping their heads facing the discharge direction. The baffles in the discharge channel divert the eels, and the gradually narrowing diversion channels allow the eels to enter the automatic gutting device one by one. The automatic gutting machine in the gutting box opens the eels by opening their backs or bellies, completing the automatic gutting. The grading device grades the eels, and the graded eels enter the automatic gutting device from different discharge channels, reducing errors in the gutting process, improving the accuracy of gutting, and avoiding adjustment time when processing eels of different sizes. This makes the operation of the gutting device smoother, and the multi-channel gutting improves production efficiency and meets the needs of large-scale production.

[0010] A further feature of the present invention is that the scalding box includes a first scalding box and a second scalding box, and the support frame is provided with a lifting mechanism for driving the scalding box to rise and fall. The first scalding box and the second scalding box are each provided with a feed inlet on one side in the horizontal direction, which matches the number and size of the diversion channels. The first scalding box and the second scalding box are provided with a discharge outlet on opposite sides in the horizontal direction, which is equal to the number of feed inlets. The automatic scalding machine is connected to each feed inlet. The types of automatic scalding machines in the first scalding box and the second scalding box are different.

[0011] By adopting the above technical solution, the gutting box includes a first gutting box and a second gutting box. The first gutting box contains multiple automatic back-opening machines arranged side by side, and the second gutting box contains multiple automatic belly-opening machines arranged side by side. When it is necessary to open the back or belly of the eel, the gutting box only needs to be raised or lowered by the lifting mechanism so that the feed inlet of the first or second gutting box is aligned with the discharge outlet of the diversion channel, so that the eel enters the gutting box for gutting. The adjustment is convenient and saves space and equipment. Different gutting methods can be switched without setting up multiple production lines.

[0012] A further configuration of the present invention is as follows: the automatic gutting machine includes an installation plate inclined towards the discharge end, the installation plate having a gutting groove extending and penetrating along the conveying direction in the middle, a guide frame for fish to pass through fixedly installed in the middle of the installation plate, the guide frame connecting the feed inlet and the discharge outlet, parallel upright plates fixedly installed on both sides of the installation plate, two parallel guide columns fixedly installed between the two upright plates, two sliding plates slidably connected to the two guide columns, a pressure drive motor fixedly installed on the sliding plates, a conveying gear disc fixedly connected to the output shaft of the pressure drive motor, the two conveying gear discs being located on both sides of the gutting groove and rotating towards each other, openings for the two conveying gear discs to pass through on both sides of the guide frame, and an adjustment mechanism for adjusting the tension between the two conveying gear discs on the two sliding plates.

[0013] By adopting the above technical solution, the automatic gutting machine includes a mounting plate fixedly installed on the gutting box. The mounting plate is provided with a gutting groove for the cutting blade to pass through. A guide frame for fish to pass through is provided above or below the gutting groove. The guide frame connects the feed inlet and the discharge outlet. The inclined mounting plate allows live eels to enter from the feed inlet and fall out from the discharge outlet after gutting. The distance between the two sliding plates can be adjusted by the adjustment mechanism, thereby adjusting the distance between the two conveying toothed discs, so that the two conveying toothed discs can clamp eels of different sizes to ensure the gutting effect.

[0014] A further configuration of the present invention is as follows: the adjustment mechanism includes a mounting bracket fixedly mounted on the mounting plate. The mounting bracket is located near the side of the automatic alignment device and symmetrically arranged with the cutting groove. A gear is rotatably connected to the center of the mounting bracket. Racks are meshed on the upper and lower sides of the gear. The racks are slidably connected to the mounting bracket. The two racks are fixedly connected to the slide plates on opposite sides. A tension spring is provided between the two slide plates. The two ends of the tension spring are fixedly connected to the slide plates. The tension of the tension spring causes the two slide plates to be in a state of being close to each other.

[0015] By adopting the above technical solution, in the initial state, the tension spring between the two slide plates keeps the two gears close together. When the live eel enters the automatic dissecting device from the feed inlet, it crawls down the inclined mounting plate with its belly facing down. When it reaches the middle of the two conveying toothed discs, the two conveying toothed discs clamp the eel and convey it to the discharge outlet. During the clamping process, the two conveying toothed discs are driven to move away from each other, causing the two slide plates to move away from each other. The tension spring is stretched, and the two racks fixedly connected to the slide plates move in opposite directions, causing the gears to rotate. Through the arrangement of the gears and racks, the two conveying toothed discs are always symmetrically arranged on both sides of the dissecting groove during the process of clamping the eel, and the eel is always in the middle of the dissecting groove, which facilitates the cutting blade to accurately dissect the eel.

[0016] A further configuration of the present invention is as follows: the automatic dissection machine includes a rotating shaft rotatably connected above or below the mounting plate, a cutting blade is fixedly mounted on the rotating shaft, the cutting blade partially passes through the dissection groove and is located between the two gears, and a pulley mechanism for driving the rotating shaft to rotate is provided inside the dissection box.

[0017] By adopting the above technical solution, when the eel needs to be opened from behind, the rotating shaft is set above the mounting plate, the guide frame is set below the mounting plate to support the eel, and the pulley mechanism is located above the mounting plate. The pulley mechanism drives the rotating shaft to rotate, so that the cutting blade on the rotating shaft opens the eel from behind. When the eel needs to be opened from the belly, the rotating shaft is set below the mounting plate, the guide frame is set above the mounting plate to limit the eel, and the pulley mechanism is located below the mounting plate. The pulley mechanism drives the rotating shaft to rotate, so that the cutting blade on the rotating shaft opens the eel from the belly.

[0018] A further configuration of the present invention is as follows: the lifting mechanism includes a fixed plate fixedly installed in the middle of both sides of the dissection box; a plurality of screw jacks are fixedly installed on the support frame; adjacent screw jacks are connected by a transmission shaft; the screw of the screw jack is rotatably connected to the fixed plate; a lifting drive motor is fixedly installed at the bottom of the support frame; a reducer is fixedly connected to the output shaft of the lifting drive motor; steering gears are driven to both sides of the reducer; and the two steering gears are driven to the screw jacks.

[0019] By adopting the above technical solution, four screw jacks, steering gears, and reducers form four linked lifting platforms. The screw rotation of the screw jacks can be controlled by the lifting drive motor, thereby controlling the lifting of the shredding box.

[0020] A further feature of the present invention is that: a vibration motor is fixedly installed on both sides of the sorting box; the sorting box includes multiple vertically arranged screening sections; the discharge end of the screening section is connected to the feeding channel; the screening section includes multiple vertically arranged adjusting plates; the multiple adjusting plates are arranged parallel to each other along the conveying direction; multiple screening bars are fixedly installed at equal intervals on the top of the adjusting plates; the screening bars are arranged parallel to each other along the conveying direction and the discharge end gradually expands; the screening bars are inclined towards the automatic alignment device; the spacing between adjacent screening bars in the screening section decreases sequentially from top to bottom; the adjusting plates are provided with multiple grooves; and one groove is provided between each adjacent screening bar.

[0021] By adopting the above technical solution, the eels enter the sorting box from the top. During the vibration of the sorting box, the inclined screening rods transport the eels towards the discharge end. The spacing between adjacent screening rods in the screening section decreases sequentially from top to bottom, so that the eels are divided into different levels of gradually decreasing size by multiple screening parts. The eels at the top are the largest and the eels at the bottom are the smallest. Since the eels have large heads and relatively small and long bodies, they are prone to getting stuck between two screening rods during the conveying process. The grooves on the multiple adjustable plates arranged at intervals support the part of the eel hanging below the two screening rods when it passes through the grooves on the adjustable plates. During the downward vibration of the eels, the hanging eels gradually become flat, preventing them from getting stuck between the two screening rods and affecting the processing efficiency. In addition, the adjustable plates keep the discharge direction of the eels uniform, so that the eel heads enter the gutting box first, ensuring the quality of gutting.

[0022] A further feature of the present invention is that the automatic dissection device is provided with a manual assistance device at the discharge end, the manual assistance device including a conveyor belt disposed at the discharge end of the automatic dissection device, a plurality of worktables disposed on both sides of the conveyor belt, and a chute fixedly installed above the conveyor belt, the chute being inclined toward the discharge end.

[0023] By adopting the above technical solution, after the eels are dislodged or gutted, they flow out through the discharge port and then through an inclined chute. Under the force of gravity or the water flow at the top of the chute, they are transported towards the discharge end. Workers on the workbench remove the heads and internal organs of the eels and place them on a conveyor belt. The conveyor belt transports the cleaned eels to one end of the automatic cleaning device to assist in the gutting process. Through the upper and lower conveyor belts and chute, the cleaned eels are separated from the uncleaned eels, ensuring the quality of the product.

[0024] A further feature of the present invention is that the discharge end of the manual assistance device is equipped with a bubble cleaning machine.

[0025] By adopting the above technical solution, the bubble cleaning machine cleans the gutted eels and discharges them.

[0026] A further configuration of the present invention is as follows: a feeding bin is provided on the side of the sorting box away from the automatic sorting device, a discharge port is provided at the bottom of the feeding bin, a control plate is slidably connected to the bottom of the feeding bin, a belt elevator is provided below the discharge port, and the discharge end of the belt elevator is connected to the feeding end of the sorting box.

[0027] By adopting the above technical solution, adjusting the position and opening of the control plate can effectively control the eel discharge speed and discharge volume. When it is necessary to increase the discharge volume, the position of the movable plate can be adjusted to increase its opening, thereby allowing more eels to flow out; conversely, when it is necessary to reduce the discharge volume, the opening of the movable plate can be reduced to limit the eel discharge speed.

[0028] The beneficial effects of this invention are:

[0029] 1. Eels enter from one end of the vibration grading device. After vibration grading, eels of different grades fall from different feeding channels to their corresponding discharge channels, keeping their heads facing the discharge direction. The baffles in the discharge channel divert the eels, and the gradually narrowing diversion channels allow the eels to enter the automatic gutting device one by one. The automatic gutting machine in the gutting box opens the eels by cutting open their backs or bellies. The grading device then grades the eels. The graded eels enter the automatic gutting device from different discharge channels, reducing errors in the gutting process and improving the accuracy of gutting. At the same time, it avoids the adjustment time when processing eels of different sizes, making the operation of the gutting device smoother. Multi-channel gutting improves production efficiency, and 7,000-10,000 eels can be gutted per hour to meet large-scale production needs.

[0030] 2. The gutting box includes a first gutting box and a second gutting box. The first gutting box contains multiple automatic back-opening machines arranged side by side, and the second gutting box contains multiple automatic belly-opening machines arranged side by side. When it is necessary to open the back or belly of the eel, the gutting box only needs to be raised or lowered by the lifting mechanism so that the feed inlet of the first or second gutting box is aligned with the discharge outlet of the diversion channel, so that the eel can enter the gutting box for gutting. It is easy to adjust and saves space and equipment. Different gutting methods can be switched without setting up multiple production lines.

[0031] 3. When a live eel enters the automatic gutting device from the feed inlet, it crawls down the inclined mounting plate with its belly facing down. When it reaches the middle of the two conveyor toothed discs, the two conveyor toothed discs clamp the eel and convey it to the discharge port. During the clamping process, the two conveyor toothed discs are driven to move away from each other, causing the two slide plates to move away from each other. The tension spring is stretched, and the two racks fixedly connected to the slide plates move in opposite directions, causing the gears to rotate. Through the arrangement of the gears and racks, the two conveyor toothed discs are always symmetrically arranged on both sides of the gutting groove during the process of clamping the eel, and the eel is always in the middle of the gutting groove, which facilitates the cutting blade to accurately gut the eel.

[0032] 4. Existing screening boxes consist of multiple parallel screening rods. Due to the large head of the eel and its relatively small and long body, the eel is prone to getting stuck between two screening rods during the conveying process. The grooves on the multiple adjustable plates in this application support the part of the eel hanging below the two screening rods as it passes through the grooves on the adjustable plates. During the downward vibration of the eel, the suspended eel gradually becomes flat, preventing it from getting stuck between the two screening rods and affecting processing efficiency. In addition, the adjustable plates keep the eel's discharge direction uniform, ensuring that the eel's head enters the gutting box first, thus guaranteeing the quality of gutting.

[0045] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0046] like Figure 1 As shown, an automated eel production line includes a feeding hopper 1, a belt conveyor 2, a vibration grading device 3, an automatic sorting device 4, an automatic gutting device 5, a manual assistance device 9, and a bubble cleaning machine 10 arranged in a horizontal direction.

[0047] The bottom of the feeding hopper 1 is provided with a discharge port 101. A control plate 102 is slidably connected to the bottom of the feeding hopper 1. A belt elevator 2 is provided below the discharge port 101. The discharge end of the belt elevator 2 is connected to the feed end of the sorting box 303. By adjusting the position and opening of the control plate 102, the discharge speed and discharge amount of eels can be effectively controlled. When it is necessary to increase the discharge amount, the position of the movable plate can be adjusted to increase its opening, thereby allowing more eels to flow out. Conversely, when it is necessary to reduce the discharge amount, the opening of the movable plate can be reduced to limit the discharge speed of eels.

[0048] like Figure 2 Figure 3As shown, the vibration grading device 3 includes a fixed frame 301, on which a sorting box 303 is fixedly connected via a compression spring 302. A feed hopper is located on the upper end of the sorting box 303 near the belt conveyor 2. Four feeding channels 304 are arranged sequentially from top to bottom at the discharge end of the sorting box 303, with the four channels 304 staggered. Vibration motors 305 are fixedly installed on both sides of the sorting box 303. The sorting box 303 includes four vertically arranged screening sections 306. More screening sections 306 can be added according to user requirements. The discharge end of the screening section 306 is connected to... The material feeding channel 304 is connected to the screening section 306, which includes multiple vertically arranged adjusting plates 307. The multiple adjusting plates 307 are arranged parallel to each other along the conveying direction. Multiple screening rods 308 are fixedly installed at equal intervals on the top of the adjusting plates 307. The screening rods 308 are arranged parallel to each other along the conveying direction and the discharge end gradually expands. The screening rods 308 are inclined towards the automatic alignment device 4. The distance between adjacent screening rods 308 in the screening section 306 decreases from top to bottom. Multiple grooves 309 are provided on the adjusting plates 307, and a groove 309 is provided between each adjacent screening rod 308.

[0049] The eels are lifted by the belt conveyor 2 to the top of the sorting box 303 and enter the sorting box 303. During the vibration of the sorting box 303, the inclined screening rods 308 transport the eels to the discharge end. The distance between adjacent screening rods 308 in the screening section 306 decreases from top to bottom, so that the eels are divided into different grades with gradually decreasing size by multiple screening sections 306. The eels at the top are the largest and the eels at the bottom are the smallest. If necessary, eels that are too large or too small can be removed, and the eels that are too large or too small can be discharged from the sides, while the eels of the middle grade are retained. Because eels have relatively large heads and relatively small and long bodies, they are prone to getting stuck between the two screening rods 308 during the conveying process. The grooves 309 on the multiple adjustable plates 307 spaced apart provide support for the part of the eel hanging below the two screening rods 308 as it passes through the grooves 309. As the eel vibrates downwards at an angle, the hanging eel gradually becomes flat, preventing it from getting stuck between the two screening rods 308 and affecting processing efficiency. In addition, the adjustable plates 307 keep the eel's discharge direction uniform, ensuring that the eel's head enters the gutting box 502 first, thus guaranteeing the quality of gutting.

[0050] like Figure 1 , Figure 4As shown, the feeding channel 304 is connected to the automatic sorting device 4. The automatic sorting device 4 includes a discharge channel 401 located at the discharge end of the feeding channel 304. The discharge channel 401 is provided with several partitions 402, with adjacent partitions 402 arranged in a V-shape. The partitions 402 divide the discharge channel 401 into several diversion channels 403 that gradually narrow along the discharge direction. Baffles are provided on both sides and the top of the diversion channels 403, and several dividing ribs are provided in the dividing channels. The V-shaped partitions 402 in the discharge channel 401 divert the eels, and the gradually narrowing diversion channels 403 allow the eels to enter the automatic gutting device 5 one by one, ensuring the gutting effect.

[0051] like Figure 5 As shown, a single eel enters the automatic gutting device 5. The automatic gutting device 5 includes a support frame 501, with a gutting box 502 slidably connected vertically to the support frame 501. The support frame 501 is equipped with a lifting mechanism 8 that drives the gutting box 502 to rise and fall. The lifting mechanism 8 includes a fixed plate 801 fixedly installed in the middle of both sides of the gutting box 502. Several screw jacks 802 are fixedly installed on the support frame 501. Adjacent screw jacks 802 are connected by a transmission shaft 803. The screw of the screw jack 802 is rotatably connected to the fixed plate 801. The screw of the screw jack is threadedly connected to the support frame 501. A lifting drive motor 806 is fixedly installed at the bottom of the support frame 501. A reducer 804 is fixedly connected to the output shaft of the lifting drive motor 806. Steering gears 805 are driven to both sides of the reducer 804. The two steering gears 805 are driven to the screw jacks 802. Four screw jacks 802, a steering gear 805, and a reducer 804 form four linked lifting platforms. The screw of the screw jack 802 can be rotated by the lifting drive motor 806, thereby controlling the lifting of the dissection box 502.

[0052] like Figure 5 As shown, the evisceration box 502 includes a first evisceration box 503 and a second evisceration box 504. Both the first evisceration box 503 and the second evisceration box 504 have feed inlets 505 on one side in the horizontal direction, which match the number and size of the diversion channels 403. The first evisceration box 503 and the second evisceration box 504 have discharge outlets 506 on opposite sides in the horizontal direction, which are equal in number to the number of feed inlets 505. Each feed inlet 505 is connected to an automatic evisceration machine 6. The automatic evisceration machines 6 in the two evisceration boxes 502 are of different types. If the automatic evisceration machine 6 in the first evisceration box 503 is an automatic evisceration machine, then the automatic evisceration machine 6 in the second evisceration box 504 is an automatic back opening machine.

[0053] like Figure 6-9As shown, the automatic gutting machine 6 includes a mounting plate 601 inclined towards the discharge end. A gutting groove 602 extending and penetrating along the conveying direction is provided in the middle of the mounting plate 601. A guide frame 603 for fish to pass through is fixedly installed in the middle of the mounting plate 601. The guide frame 603 in the first gutting box 503 is installed on the upper surface of the mounting plate 601, and the guide frame 603 in the second gutting box 504 is installed on the lower surface of the mounting plate 601. The guide frame 603 connects the feed inlet 505 and the discharge outlet 506. Parallel vertical plates 604 are fixedly installed on both sides of the mounting plate 601. Two parallel guide columns 605 are fixedly installed between the two vertical plates 604. Two sliding plates 606 are slidably connected to the two guide columns 605. A clamping drive is fixedly installed on the sliding plates 606. The output shaft of the pressure drive motor 607 is fixedly connected to a conveying gear 608. The two conveying gears 608 are located on both sides of the slicing groove 602 and rotate towards each other. The guide frame 603 has openings 609 on both sides for the two conveying gears 608 to pass through. It should be noted that since the guide frame 603 in the first slicing box 503 is installed on the upper end face of the mounting plate 601, the two conveying gears 608 are also set on the upper end face of the two mounting plates 601. The guide frame 603 in the second slicing box 504 is installed on the lower end face of the mounting plate 601. The output shaft of the pressure drive motor 607 passes through the sliding plate 606 and the mounting plate 601 and is fixedly connected to the conveying gears 608. The conveying gears 608 are located on the lower end face of the mounting plate 601.

[0054] like Figure 6 and Figure 8 As shown, the two slide plates 606 are provided with an adjustment mechanism 7 for adjusting the tension between the two conveying toothed discs 608. The adjustment mechanism 7 includes a mounting bracket 701 fixedly mounted on the mounting plate 601. The mounting bracket 701 is located near the automatic alignment device 4 and is symmetrically arranged with the cutting groove 602. A gear 702 is rotatably connected to the center of the mounting bracket 701. A rack 703 is meshed on the upper and lower sides of the gear 702. The rack 703 is slidably connected to the mounting bracket 701. The two racks 703 are fixedly connected to the slide plates 606 on the side away from each other. A tension spring 704 is provided between the two slide plates 606. The two ends of the tension spring 704 are fixedly connected to the slide plates 606. The tension of the tension spring 704 keeps the two slide plates 606 in a state of close proximity.

[0055] Initially, the tension spring 704 between the two slide plates 606 keeps the two gears 702 close together. When a live eel enters the automatic gutting device 5 from the feed inlet 505 and crawls down the inclined mounting plate 601 with its belly facing down, it reaches the middle of the two conveying toothed discs 608. The two conveying toothed discs 608 clamp the eel and convey it to the discharge outlet 506. During the clamping process, the two conveying toothed discs 608 are driven to move away from each other, causing the two slide plates 606 to move away from each other. The tension spring 704 is stretched, and the two racks 703, which are fixedly connected to the slide plates 606, move in opposite directions, causing the gears 702 to rotate. Through the arrangement of the gears 702 and racks 703, the two conveying toothed discs 608 are always symmetrically arranged on both sides of the gutting groove 602 during the process of clamping the eel. The eel is always in the middle of the gutting groove 602, which facilitates the cutting blade 611 to accurately gut the eel.

[0056] The automatic dissecting machine 6 includes a rotating shaft 610 rotatably connected above or below a mounting plate 601. A cutting blade 611 is fixedly mounted on the rotating shaft 610. The cutting blade 611 partially passes through a dissecting groove 602 and is located between two gears 702.

The pulley mechanism 612 is located below the mounting plate 601, and the pulley mechanism 612 drives the rotating shaft 610 to rotate, causing the cutting blade 611 on the rotating shaft 610 to gut the eel; Figure 6 , Figure 7 As shown, when the eel needs to be gutted, the rotating shaft 610 inside the second gutting box 504 is positioned above the mounting plate 601, and the guide frame 603 is positioned below the mounting plate 601 to support the eel. The pulley mechanism 612 is located above the mounting plate 601, and the pulley mechanism 612 drives the rotating shaft 610 to rotate, causing the cutting blade 611 on the rotating shaft 610 to gut the eel. It should be noted that the size of the cutting blade 611 inside the feed inlets 505 varies depending on the grade. When the eel is large, the size of the cutting blade 611 is larger, and when the eel is small, the size of the cutting blade 611 is smaller, in order to ensure the quality of gutting.

[0057] like Figure 1As shown, the automatic gutting device 5 is equipped with a manual assistance device 9 at its discharge end. The manual assistance device 9 includes a conveyor belt 901 set at the discharge end of the automatic gutting device 5. Several workbenches 902 are set on both sides of the conveyor belt 901. A chute 903 is fixedly installed above the conveyor belt 901. The chute 903 is inclined towards the discharge end. After the eels with their backs or bellies cut open are discharged through the discharge port 506, they flow out from the inclined chute 903. Under the force of gravity or the force of the water flow at the upper end of the chute 903, they are transported towards the discharge end. The workers on the workbenches 902 remove the heads and internal organs of the eels and place them on the conveyor belt 901. The conveyor belt 901 transports the cleaned eels to one end of the automatic cleaning device to assist in completing the gutting. Through the upper and lower set conveyor belt 901 and chute 903, the cleaned eels are separated from the uncleaned eels to ensure the quality of the product.

[0058] The discharge end of the manual auxiliary device 9 is equipped with a bubble cleaner 10, which cleans the gutted eel and discharges it.
