Description

Technical Field

[0001] This invention relates to the field of sea cucumber processing equipment, and more specifically, to a fully automatic sea cucumber cleaning device. Background Technology

[0002] Sea cucumber, a highly nutritious seafood delicacy, is loved by consumers. With the continuous growth of market demand, the scale of artificial breeding and processing of sea cucumber has expanded rapidly. In the sea cucumber processing, cleaning is a crucial pre-processing step, the effect of which directly affects the quality of subsequent processing (such as steaming, boiling, and rehydration) and the taste, appearance, and hygiene and safety of the final product.

[0003] Currently, in the automated cleaning and processing of sea cucumbers, due to the complex abdominal cavity structure, soft inner wall, and easy retention of internal organs, existing cleaning methods such as brush roller rolling cleaning and high-pressure water direct spraying cannot simultaneously achieve effective expansion of the abdominal cavity, thorough removal of residues, and protection of tissue integrity. This easily leads to problems such as many cleaning dead corners, high sea cucumber damage rate, and unstable cleaning effect, ultimately failing to meet the processing requirements of energy-saving agricultural and sideline processing equipment for high cleanliness and low damage automated cleaning.

[0004] Therefore, this application proposes an all-round automatic cleaning device for sea cucumbers to solve the above problems. Summary of the Invention

[0005] Technical problem to be solved: In view of the problems existing in the prior art, the purpose of this invention is to provide an all-round automatic cleaning device for sea cucumbers, which solves the problem that the existing sea cucumber cleaning methods cannot simultaneously achieve abdominal cavity expansion, internal organ removal and tissue protection, resulting in many cleaning dead corners and high damage rate.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an all-round automatic cleaning device for sea cucumbers, including a frame and a feeding platform installed at the front of the frame. A water tank is provided at the lower part of the frame, and a water circulation filter assembly for drawing water from the water tank is provided on the outside of the frame. Multiple parallel diamond-shaped unfolding and flattening guide modules are installed on the top of the feeding platform. Two parallel conveying assemblies are provided inside the frame. Each of the two conveying assemblies is equipped with a spray assembly connected to the water circulation filter assembly. A progressive cleaning assembly is provided between the two conveying assemblies. The progressive cleaning assembly includes a rewashing platform placed in the middle of the frame and an assembly for connecting the rewashing platform to the conveying assembly. Several progressively widening strips with gradually increasing width are arranged equidistantly on the upper surface of the rewashing platform along the feeding direction. Multiple bidirectional oblique nozzles are equidistantly provided in the progressively widening strips. The progressively widening structure of the progressively widening strips gradually expands the abdominal cavity of the sea cucumber after the initial spraying and water absorption, and the bidirectional oblique nozzles are used to perform a second rinsing inside the cavity to remove internal viscera residue.

[0007] In a new embodiment, the conveying assembly includes: an upper conveyor installed on the upper side of the middle of the frame; a lower conveyor installed on the lower side of the middle of the frame; and a stainless steel mesh conveyor belt respectively fitted onto the upper and lower conveyors, the stainless steel mesh conveyor belt being made of 304 stainless steel; an installation gap is provided between the upper and lower conveyors, the installation gap being defined by the installation positions of the upper and lower conveyors and the winding path of the stainless steel mesh conveyor belt, the installation gap being used to accommodate the installation of the washing platform; multiple parallel support plates are also installed in the middle of the upper and lower conveyors to provide continuous planar support for the stainless steel mesh conveyor belt; the upper and lower conveyors form an upper and lower clamping conveying channel through the stainless steel mesh conveyor belt, and the sea cucumber is clamped between the upper and lower mesh conveyor belts during the conveying process.

[0008] In a new embodiment, the spray assembly includes: two assembly frames, which are respectively installed on the top of the upper conveyor and the bottom of the lower conveyor; two sets of spray bars, which are equidistantly installed at the front and rear of the assembly frame, and multiple spray heads are equidistantly installed on the inward side of each spray bar; and branch pipes, which are located on one side of the spray bars and connected to the water inlet end of each spray bar through pipelines.

[0009] In a new embodiment, the top of the rewashing platform is provided with a pushing assembly for moving the gradually expanding sea cucumber strips. The pushing assembly includes a top cover, a loading plate, and a conveyor belt. The top cover is installed on the top of the rewashing platform. The loading plate is slidably installed inside the top cover. A conveyor belt is installed at the bottom of the loading plate. Multiple parallel pushing strips are fixed at equal intervals on the conveyor belt. Each pushing strip is composed of multiple pushing strips. The bottom of the pushing strips is provided with textures or protrusions to increase friction. Hydraulic rods are installed at the four corners of the top of the top cover. The telescopic ends of the hydraulic rods are fixedly connected to the corresponding positions at the top of the loading plate.

[0010] In a new embodiment, a plurality of adhesive removal components are installed on the front and rear sides of the top wall of the mounting plate, the adhesive removal components on the front and rear sides are arranged in a mirror symmetrical manner, and the adhesive removal components are made of food-grade engineering plastic material.

[0011] In a new embodiment, a guide assembly is provided between the washing platform and the upper cover platform. The guide assembly includes a lower guide plate, an upper guide plate, and a guide shaft assembly. The lower guide plates are installed at the front and rear ends of the washing platform, and the upper surface of the lower guide plates is flush with the upper surface of the washing platform. The upper guide plates are installed at the front and rear ends of the upper cover platform, and an entrance and exit for sea cucumbers to pass through are provided between the upper and lower guide plates. Multiple sets of guide shaft assemblies are provided between the lower and upper guide plates. Each set of guide shaft assemblies includes two guide rollers that rotate in opposite directions. The centerline of each set of guide shaft assemblies is aligned with the centerline of the corresponding spreading strip. The guide shaft assemblies are used to guide the sea cucumbers to move onto the spreading strip.

[0012] In a new embodiment, each of the expanding strips is provided with a raised plate installed on the top of the rewashing platform on both the left and right sides. Multiple weak spring columns are equidistantly slidably installed on the inward side of the raised plate, and a contact soft block is installed on the inward end of each weak spring column.

[0013] In a new embodiment, an arc-shaped grid plate is installed on the upper surface of the rewashing platform on the left and right sides of each expansion bar, and the arc-shaped grid plate is located between the expansion bar and the protruding plate on the corresponding side, so as to intercept the sea cucumber viscera residue that has been washed off.

[0014] In a new embodiment, the bottom of the rewashing platform is provided with a transverse pipe, which is connected to the bidirectional oblique nozzle in each progressive spreader through multiple node pipes; the outer surface of the progressive spreader is covered with a food-grade wear-resistant material layer with a low coefficient of friction.

[0015] In a new embodiment, the water circulation filtration assembly includes: an external base platform disposed on the outside of the frame; a high-pressure pump and a water purification device are respectively installed on the top of the external base platform; the pumping end of the high-pressure pump is connected to the outlet of the water tank through a pipeline, the draining end of the high-pressure pump is connected to the inlet of the water purification device through a pipeline, and the outlet of the water purification device is connected to the inlet of a branch pipe through a pipeline; the branch pipe is also connected to a horizontal pipe through a pipeline equipped with a solenoid valve.

[0016] Beneficial effects: Compared with the prior art, the advantages of this invention are as follows: 1. This application guides the manual unfolding and flattening of the cut sea cucumbers through the diamond-shaped guide module of the feeding platform, laying the foundation for subsequent standardized cleaning. The conveying component stably clamps and conveys the sea cucumbers, and with the help of the progressive expansion strips and bidirectional oblique nozzles in the progressive expansion cleaning component, it addresses the problem of the sea cucumbers absorbing water and shrinking after the initial cleaning, making it difficult to clean the abdominal cavity. It works together to achieve non-damaging progressive expansion of the shrinking abdominal cavity and deep cleaning of the internal organs. With the help of the water circulation filtration component, water is recycled, which effectively solves the problem that the existing cleaning equipment cannot effectively handle the shrinking abdominal cavity of sea cucumbers and cannot simultaneously achieve thorough cleaning of internal organs and tissue protection, resulting in incomplete cleaning of sea cucumbers, high damage rate and decreased pass rate.

[0017] 2. By setting up a progressive expansion cleaning component, the rewashing platform surface is equipped with progressively wider expansion strips. As the sea cucumber is pushed along the expansion strips by the pushing component, its abdominal cavity, which has contracted due to water absorption, is slowly and steadily expanded. This effectively avoids tearing of the sea cucumber's body wall caused by sudden and forceful expansion. At the same time, the bidirectional oblique nozzles embedded in the expansion strips spray water at a specific angle to both sides, directly rinsing the expanded abdominal cavity wall and thoroughly removing visceral residues attached to folds and dead corners, achieving efficient and gentle abdominal cavity cleaning.

[0018] 3. The progressive cleaning component, pushing component, and guiding component work together to ensure the continuity and stability of the sea cucumber cleaning process. The guiding component, through the lower guide plate, upper guide plate, and grouped guide shafts, precisely guides the sea cucumbers that have undergone the initial cleaning from the conveying component to the re-washing platform, ensuring that their abdominal opening is aligned with the starting end of the progressive cleaning strip, thus preparing for the subsequent expansion and cleaning of the contracted abdominal cavity. The pushing component flexibly adjusts the pushing pressure through hydraulic rods, driving the sea cucumbers to move smoothly along the progressive cleaning strip, which not only adapts to sea cucumbers of different sizes but also ensures that the sea cucumbers do not slip or get squeezed and damaged during the pushing process.

[0019] 4. In the actual operation of the progressive rinsing component, in response to the potential left-right deviation of sea cucumbers, this application sets up an effective limiting and correction structure on the rewashing platform. On both sides of each progressive rinsing bar, there are protruding plates with weak spring pillars. The contact soft blocks at the ends of the weak spring pillars contact the sides of the sea cucumber with a gentle and continuous elastic force, automatically correcting its movement trajectory without damaging the epidermis, ensuring that the sea cucumber always moves along the center line of the progressive rinsing bar, thereby ensuring that the rinsing water flow from the bidirectional oblique nozzles can fully cover the inner wall of the abdominal cavity, significantly reducing cleaning dead corners.

[0020] 5. The overall structure of this device takes into account both space utilization and cleaning sustainability. The installation gap between the upper and lower conveyors in the conveying assembly is used to reasonably embed the rewashing platform, which greatly saves the overall space of the equipment. It is especially suitable for small and medium-sized processing sites. At the same time, the water circulation filtration assembly uses a high-pressure pump and a water purification device to centrally filter and purify the cleaning wastewater, realizing the recycling of water resources. This not only reduces the environmental burden but also lowers production costs, meeting the processing requirements of energy-saving agricultural and sideline processing equipment.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0039] This application provides an all-around automatic sea cucumber cleaning device. Existing sea cucumber cleaning methods cannot simultaneously achieve abdominal cavity expansion, visceral removal, and tissue protection, resulting in many cleaning dead spots and a high damage rate. In use, the diamond-shaped unfolding and flattening guide module is used to initially unfold and flatten the input sea cucumber. Then, with the help of the progressive expansion and cleaning components, the progressive expansion strips and bidirectional oblique nozzles work together to achieve non-damaging secondary expansion and internal cleaning of the sea cucumber's abdominal cavity, further enhancing the all-around cleaning of the sea cucumber and improving the cleaning qualification rate and efficiency.

[0040] The technical solutions in this application are intended to solve the above-mentioned technical problems, and the overall approach is as follows.

[0041] Example 1, please refer to Figures 1-15 This application provides an all-around automatic sea cucumber cleaning device, including a frame 1, a feeding platform 2 installed at the front of the frame 1, a water tank 3 at the bottom of the frame 1, and a water circulation filter assembly 4 for drawing water from the water tank 3 on the outside of the frame 1. Multiple parallel-arranged diamond-shaped unfolding and flattening guide modules 21 are installed on the top of the feeding platform 2. Two parallel conveying assemblies 5 are provided inside the frame 1, and each of the two conveying assemblies 5 is equipped with a spray assembly 6 connected to the water circulation filter assembly 4. A [missing information - likely a design feature] is provided between the two conveying assemblies 5. There is a progressive expansion cleaning component 7; the progressive expansion cleaning component 7 includes: a rewashing platform 71 placed in the middle of the frame 1 and an assembly 72 for connecting the rewashing platform 71 to the conveying assembly 5. The upper surface of the rewashing platform 71 has several progressively widening strips 73 arranged at equal intervals along the feeding direction. Multiple bidirectional oblique nozzles 74 are arranged at equal intervals in the progressive expansion strips 73. The progressive expansion structure of the progressive expansion strips 73 gradually expands the abdominal cavity of the sea cucumber after the initial spraying and water absorption, and the bidirectional oblique nozzles 74 are used to perform a second rinsing inside the cavity to remove visceral residue.

[0042] This application adopts standardized processing, precise transportation, deep cleaning, and recycling as its core concepts. Relying on the diamond-shaped unfolding and flattening guide module 21, it guides the manual unfolding and flattening of the already cut sea cucumbers and sends them into the transportation channel between the upper conveyor 51 and the lower conveyor 52. The upper conveyor 51 and the lower conveyor 52, together with the stainless steel mesh conveyor belt 53, form a stable clamping and transportation system to spray the flattened sea cucumbers. During this process, in response to the problem of the sea cucumbers absorbing water and shrinking after the initial cleaning, and the difficulty in cleaning the abdominal cavity, the progressive expansion and cleaning component 7 uses the progressive expansion bar 73 and the bidirectional oblique nozzle 74 to perform non-damaging expansion of the shrinking abdominal cavity and deep rinsing of internal viscera residue. Combined with the water circulation filtration component 4, wastewater filtration and reuse are realized, achieving all-round automated cleaning of sea cucumbers.

[0043] Specifically, the working principle of this all-around automatic sea cucumber cleaning device is as follows: First, the staff places the manually cut sea cucumber belly-down against the diamond-shaped guide module 21 of the feeding platform 2. The diamond structure guides the staff to unfold and flatten the abdominal cavity of the sea cucumber, and then puts it into the conveying component 5. The unfolded and flattened sea cucumber enters the clamping channel composed of the upper conveyor 51 and the lower conveyor 52. The upper and lower layers of the channel are equipped with stainless steel mesh conveyor belts 53. On the one hand, the upper and lower clamping achieves the fixation of the sea cucumber posture (preventing it from rolling and shifting during transportation). On the other hand, the mesh structure does not cover the surface of the sea cucumber, leaving space for subsequent spray cleaning, achieving dual preparation for positioning and waiting for washing. Second, when the sea cucumber enters the front section through the conveyor channel, it triggers the spray assembly 6 set up between the upper conveyor 51 and the lower conveyor 52. The spray rods 62 evenly distributed on the spray assembly 6 spray clean water onto the upper and lower surfaces of the sea cucumber, completing the first cleaning of surface dirt (such as mud and mucus). This cleaning also causes the sea cucumber to absorb water, resulting in the contraction of its abdominal cavity, which increases the difficulty of cleaning the internal organs. After the initial cleaning and the contracted sea cucumber, it is guided by the front guide assembly 9 (supported by the lower guide plate 91, limited by the upper guide plate 92, and assisted by the guide shaft assembly 93) and falls precisely into the rewashing platform 71 of the progressive expansion cleaning assembly 7. The opening of the sea cucumber's abdomen is directly facing the expansion bar 73 on the rewashing platform 71. The expansion bar 73 enters the sea cucumber's abdomen, thus entering the deep cleaning stage of the sea cucumber's abdominal cavity. Third, the gradually expanding strips 73 on the rewashing platform 71 have a gradually changing structure, narrow at the inlet end and wide at the outlet end. The sea cucumbers are driven to move by the pushing component 8 (the pushing component 8 drives the pushing belt 84 through the conveyor belt 83, and the pushing strips 841 on the surface of the pushing belt 84 directly contact the sea cucumbers, thereby driving the sea cucumbers to move continuously towards the outlet end). As the sea cucumbers move along the gradually expanding strips 73, the width of the gradually expanding strips 73 gradually increases, slowly opening up the abdominal cavity of the sea cucumbers that have shrunk due to water absorption (avoiding tearing damage to the sea cucumbers caused by one-time expansion). During the opening and movement process, the surface of the gradually expanding strips 73 is equipped with bidirectional oblique nozzles 74, which spray high-pressure water jets onto the inner wall of the abdominal cavity of the sea cucumbers at an angle on both sides to rinse away the viscera residue (the bidirectional spray covers the dead corners on both sides of the abdominal cavity, solving the problem of the inner side not being cleaned properly by traditional cleaning). The pushing component 8 adjusts the height of the mounting plate 82 via the hydraulic rod 85 (i.e., adjusts the gap between the conveyor belt 83 and the washing platform 71). On the one hand, the gap can be adjusted according to the sea cucumbers of the conveying specifications. On the other hand, the pushing belt 84 on the conveyor belt 83 pushes the sea cucumbers with appropriate pressure (made of food-grade engineering plastic and with anti-slip texture on the bottom, which avoids slipping and prevents excessive squeezing and damage to the sea cucumbers). It should be noted that since the conveyor belt 83 and the pusher belt 84 can only provide pushing force for the top sea cucumber, the sea cucumber pushed on the spreading bar 73 will deviate to the left and right. At this time, the weak spring columns 712 provided on both sides of the washing platform 71, and the multiple weak spring columns 712 and the contact soft blocks 713 connected to their ends intermittently contact the two sides of the sea cucumber, so that the sea cucumber maintains a stable pushing state and ensures that the sea cucumber moves along the central trajectory of the spreading bar 73, so as to better carry out the abdominal cleaning operation. Secondly, the curved grid plate 714 at the bottom of the rewashing platform 71 allows the washing wastewater to pass through while trapping the sea cucumber viscera residue washed down by the high-pressure water. The trapped waste residue is temporarily left on the curved grid plate 714, achieving preliminary separation of residue and water, reducing the processing pressure of the subsequent water circulation filter component 4. Based on the total amount of sea cucumbers washed in a day, the staff can judge the degree of viscera retention in the curved grid plate 714 and then carry out regular dismantling and cleaning. Fourth, the sea cucumbers that have completed the abdominal cavity cleaning are guided by the rear guide assembly 9. The guide rollers rotating in opposite directions in the guide shaft assembly 93 form a clamping force, and the sea cucumbers return to the rear section of the clamping channel of the upper conveyor 51 and the lower conveyor 52, triggering the rear half of the spray bar 62 of the spray assembly 6 to spray the sea cucumbers a second time (to remove the internal visceral debris and washing liquid remaining from the abdominal cavity cleaning), and finally the clean sea cucumbers are discharged. Fifth, the wastewater generated during cleaning is collected in water tank 3 and pumped into water purification device 43 by high-pressure pump 42 connected to water tank 3 in water circulation filter assembly 4 for multi-layer filtration (such as filtering waste residue with filter screen and adsorbing impurities with activated carbon), forming clean circulating water. Then, through external control device, the circulating water is allocated as needed according to the real-time water demand of each spray structure (such as spray assembly 6 and bidirectional inclined nozzle 74), while a small amount of fresh water is added to form a closed-loop process of filtration, allocation and reuse, which avoids secondary pollution, significantly improves water resource utilization, and reduces water consumption costs.

[0044] Please see Figure 7 and Figure 16 The conveying assembly 5 includes: an upper conveyor 51, installed on the upper side of the middle of the frame 1; a lower conveyor 52, installed on the lower side of the middle of the frame 1; and a stainless steel mesh conveyor belt 53, respectively fitted onto the upper conveyor 51 and the lower conveyor 52, and the stainless steel mesh conveyor belt 53 is made of 304 stainless steel; an installation gap 54 is provided between the upper conveyor 51 and the lower conveyor 52, which is defined by the installation positions of the upper conveyor 51 and the lower conveyor 52 and the winding path of the stainless steel mesh conveyor belt 53, and the installation gap 54 is used to accommodate the installation of the washing platform 71; multiple parallel support plates 55 are also installed in the middle of the upper conveyor 51 and the lower conveyor 52 to provide continuous planar support for the stainless steel mesh conveyor belt 53; the upper conveyor 51 and the lower conveyor 52 form an upper and lower clamping conveying channel through the stainless steel mesh conveyor belt 53, and the sea cucumber is clamped between the upper and lower mesh conveyor belts during the conveying process.

[0045] By setting up an upper conveyor 51, a lower conveyor 52, a stainless steel mesh conveyor belt 53, an installation gap 54, and a support plate 55, the support plate 55 firstly stabilizes the hollow state of the stainless steel mesh conveyor belt 53, ensuring its conveying stability and preventing the mesh structure from shifting. The installation gap 54 is precisely defined by the positions of the upper conveyor 51 and the lower conveyor 52 and the winding path of the stainless steel mesh conveyor belt 53, which perfectly accommodates the embedding of the rewashing platform 71, allowing sea cucumbers to directly enter the cleaning station from the clamping channel. The nested arrangement allows the conveying component 5 and the rewashing platform 71 to share space, resulting in better space utilization and connecting the sea cucumber cleaning process. This is suitable for the limited space of small and medium-sized factories and reduces the risk of morphological damage during the conveying process.

[0046] Please see Figure 4 The spray assembly 6 includes: an assembly frame 61, of which two are provided, installed on the top of the upper conveyor 51 and the bottom of the lower conveyor 52 respectively; two sets of spray bars 62, which are installed at equal intervals on the front and rear parts of the assembly frame 61 respectively, and multiple spray heads are installed at equal intervals on the inward side of each spray bar 62; and a branch pipe 63, which is provided on one side of the spray bar 62 and is connected to the water inlet end of each spray bar 62 through a pipeline.

[0047] By setting up assembly frames 61 and spray bars 62, the two sets of assembly frames 61 correspond to the top of the upper conveyor 51 and the bottom of the lower conveyor 52, respectively. Spray bars 62 (spray heads are high-pressure nozzles) are arranged at equal intervals at the front and rear of each set of assembly frames 61. The circulating water of the water purification device 43 is evenly distributed to each spray bar 62 through the branch pipe 63 and pipeline, thereby forming a spray structure that sandwiches from the top and bottom and relays from the front and back. When the sea cucumber enters the front section of the conveying channel, it is first cleaned by the initial washing spray bar 62 to clean the front and back of the sea cucumber. After the abdominal cavity is cleaned, it is then cleaned by the rear spray bar 62 for a second cleaning to remove residual impurities from the sea cucumber.

[0048] Please see Figure 9 The top of the rewashing platform 71 is equipped with a pushing assembly 8 that pushes the expansion strip 73 to move. The pushing assembly 8 includes a top cover 81, a mounting plate 82, and a conveyor belt 83. The top cover 81 is installed on the top of the rewashing platform 71. The mounting plate 82 is slidably installed inside the top cover 81. The conveyor belt 83 is installed at the bottom of the mounting plate 82. Multiple parallel pushing belts 84 are fixed at equal intervals on the belt of the conveyor belt 83. Each pushing belt 84 is composed of multiple pushing strips 841. The bottom of the pushing strips 841 is provided with textures or protrusions to increase friction. Hydraulic rods 85 are installed at the four corners of the top of the top cover 81. The telescopic ends of the hydraulic rods 85 are fixedly connected to the corresponding positions at the top of the mounting plate 82.

[0049] By setting up a top cover platform 81, a mounting plate 82, and a conveyor belt 83, the height of the mounting plate 82 (i.e., the distance between the conveyor belt 83 and the washing platform 71) can be adjusted first using a hydraulic rod 85. This controls the contact pressure between the pushing belt 84 on the conveyor belt 83 and the surface of the sea cucumber. This not only adapts to sea cucumbers of a certain size and hardness, avoiding damage to the sea cucumber skin and deformation due to excessive pressure, but also ensures sufficient pushing force for pushing the sea cucumber through appropriate pressure. Secondly, the design of the pusher belt 84 can be further optimized. The width of the pusher strips 841 on the parallel pusher belts 84 is set to different widths in sequence (the width increases from left to right). Corresponding to this improvement, different pusher belts 84 can be adapted to push sea cucumbers of different sizes. That is, from left to right, each pusher belt 84 is matched with small, medium and large sea cucumbers in sequence, so that the width of the pusher strips 841 is adapted to the size of sea cucumbers of different sizes, ensuring that sea cucumbers of different sizes can obtain a stable pushing force and realize the synchronous processing of sea cucumbers of different sizes. This can be achieved simply by adjusting the feeding position of the sea cucumbers.

[0050] It is important to note that the pusher bar 841 is made of food-grade engineering plastic, which fully complies with the safety standards for food contact materials and meets the hygiene compliance requirements for sea cucumber processing. At the same time, the anti-slip texture / protrusions on its bottom can significantly increase the friction with the surface of the sea cucumber. Even if the sea cucumber surface is covered with mucus (a common state before cleaning), it can effectively prevent slippage during transport, ensure the stability of the sea cucumber during the pusher process, and avoid cleaning leaks or secondary damage caused by slippage.

[0051] Please see Figure 14 Multiple anti-adhesion components 821 are installed on the front and rear sides of the top wall of the mounting plate 82. The anti-adhesion components 821 are arranged in a mirror symmetrical manner and are made of food-grade engineering plastic material. By setting the anti-adhesion components 821, since sea cucumbers are prone to secreting sticky mucus during transportation, even if the pusher strip 841 is made of non-stick material, there will still be mucus adhering to its surface after long-term pushing. The mirror symmetrical anti-adhesion components 821 can be driven by the forward transmission of the conveyor belt 83 (and the reverse transmission when the conveyor belt 83 is not in operation; the forward transmission is normal feeding and discharging, and the reverse transmission is the opposite operation) to remove the residual mucus that rides on the front and rear surfaces of the pusher strip 841. It should be noted that the anti-adhesion components 821 also need to be manually cleaned regularly.

[0052] Please see Figure 13 and Figure 16 A guide assembly 9 is provided between the washing platform 71 and the upper cover platform 81. The guide assembly 9 includes a lower guide plate 91, an upper guide plate 92, and a guide shaft assembly 93. The lower guide plate 91 is installed at both the front and rear ends of the washing platform 71, and the upper surface of the lower guide plate 91 is flush with the upper surface of the washing platform 71. The upper guide plate 92 is installed at both the front and rear ends of the upper cover platform 81, and an entrance and exit for sea cucumbers to pass through are provided between the upper guide plate 92 and the lower guide plate 91. Multiple sets of guide shaft assemblies 93 are provided between the lower guide plate 91 and the upper guide plate 92. Each set of guide shaft assemblies 93 includes two guide rollers that rotate in opposite directions. The center line of each set of guide shaft assemblies 93 is aligned with the center line of the corresponding spreading strip 73. The guide shaft assemblies 93 are used to guide the sea cucumbers to move onto the spreading strip 73.

[0053] By setting up a lower guide plate 91, an upper guide plate 92, and a guide shaft assembly 93, the center line of the guide shaft assembly 93 is precisely aligned with the center line of the progressive expansion bar 73. This ensures that after the sea cucumber is guided by the guide assembly 9, the opening of the sea cucumber's abdomen is precisely aligned with the feed end of the progressive expansion bar 73. This avoids the progressive expansion bar 73 failing to open the abdominal cavity smoothly due to sea cucumber deviation, or dead corners in viscera cleaning caused by deviation in the opening position. This directly ensures the integrity of the subsequent progressive expansion cleaning, allowing the high-pressure water flow from the bidirectional oblique nozzle 74 to accurately cover the inner wall of the abdominal cavity, improving the viscera residue removal rate and indirectly improving the product qualification rate. Secondly, each guide shaft group 93 consists of two guide rollers rotating in opposite directions, forming a flexible clamping force. The synchronous reverse rotation of the rollers actively guides the sea cucumber to move, preventing the sea cucumber from shifting due to inertia when entering / leaving the washing platform 71. At the same time, the guide rollers are equipped with anti-slip sleeves to prevent slippage caused by contact with the sea cucumber.

[0054] Please see Figures 9-11 Each expansion bar 73 has a raised plate 711 installed on the top of the washing platform 71 on both the left and right sides. Multiple weak spring columns 712 are equidistantly slidably installed on the inward side of the raised plate 711. A contact soft block 713 is installed on the inward end of each weak spring column 712.

[0055] By setting up a raised plate 711, a weak spring column 712, and a contact soft block 713, the weak spring columns 712 on the left and right sides of the spreading bar 73 can form a flexible clamping force through pre-pressure to address the problem that pushing the top of the pushing component 8 can easily cause the sea cucumber to shift to the left or right. On the one hand, this automatically corrects the sea cucumber's transport trajectory, ensuring that the sea cucumber always moves along the center line of the spreading bar 73, avoiding positional deviation when the spreading bar 73 opens the abdominal cavity due to offset. On the other hand, the stable clamping posture allows the high-pressure water flow from the bidirectional oblique nozzle 74 to accurately cover the inner wall of the sea cucumber's abdominal cavity, reducing cleaning dead angles caused by the sea cucumber's shaking, and directly improving the removal rate of visceral residue.

[0056] Among them, the contact soft block 713 is made of food-grade flexible material, which has no hard friction when in contact with the sea cucumber skin. This can avoid the damage to the sea cucumber skin and the deformation of the flesh caused by traditional rigid limiting. At the same time, the weak elasticity of the weak spring column 712 can automatically adjust the amount of expansion and contraction according to the size of the sea cucumber. When facing a large sea cucumber, the weak spring column 712 is moderately compressed to increase the clamping space; when facing a small sea cucumber, the weak spring column 712 naturally extends to maintain the clamping force. This not only prevents the sea cucumber from shifting when the expansion strip 73 expands the abdominal cavity, but also avoids excessive compression that damages the shape of the sea cucumber, significantly improving the appearance qualification rate of the finished sea cucumber.

[0057] Please see Figures 9-11 The upper surface of the rewashing platform 71 is equipped with arc-shaped grid plates 714 on both the left and right sides of each expanding bar 73. The arc-shaped grid plates 714 are located between the expanding bar 73 and the raised plate 711 on the corresponding side. The arc-shaped grid plates 714 are used to intercept the sea cucumber viscera residue that falls off during cleaning. By setting the arc-shaped grid plates 714, which are arranged between the expanding bar 73 and the raised plate 711, this position is exactly the core path of the residue falling after the bidirectional oblique nozzle 74 washes the abdominal cavity. It can intercept the sea cucumber viscera fragments washed down by the high-pressure water flow in real time for collection, which is convenient for subsequent manual cleaning. The position of the arc-shaped grid plates 714 can well ensure the cleanliness of both sides of the expanding bar 73.

[0058] Please see Figure 7 and Figure 8 The bottom of the rewashing platform 71 is provided with a horizontal pipe 75, which is connected to the bidirectional oblique nozzle 74 in each progressive strip 73 through multiple node pipes 76; the outer surface of the progressive strip 73 is covered with a food-grade wear-resistant material layer with a low coefficient of friction.

[0059] By setting up horizontal pipes 75 and node pipes 76, the horizontal pipes 75 are used as the main water supply pipes, and the node pipes 76 are vertically connected to the bidirectional oblique nozzles 74 of each progressive strip 73 through equidistantly distributed nodes, forming a diversion structure of main pipe, branch pipes and nozzles: on the one hand, the clean circulating water delivered by the water circulation filter assembly 4 can be evenly distributed to all nozzles, and on the other hand, the balanced water flow intensity can ensure that the rinsing time and rinsing force of the abdominal cavity wall of each sea cucumber are consistent, and the internal viscera residue removal rate is stable.

[0060] Please see Figure 2 The water circulation filter assembly 4 includes: an external base 41, which is located on the outside of the frame 1; a high-pressure pump 42 and a water purification device 43 are respectively installed on the top of the external base 41; the water intake end of the high-pressure pump 42 is connected to the water outlet of the water tank 3 through a pipeline, the water discharge end of the high-pressure pump 42 is connected to the water inlet end of the water purification device 43 through a pipeline, and the water outlet end of the water purification device 43 is connected to the water inlet end of the branch pipe 63 through a pipeline; the branch pipe 63 is also connected to the horizontal pipe 75 through a pipeline with a solenoid valve.

[0061] By setting up an external base 41, a high-pressure pump 42, and a water purification device 43, the high-pressure pump 42 pumps the wastewater collected in the water tank 3 into the water purification device 43 (which undergoes multi-layer filtration, with the filter screen intercepting residues or activated carbon adsorbing impurities). The purified circulating water is then transported through pipelines to the branch pipe 63 and the horizontal pipe 75 to provide a water source for the spray assembly 6 and the progressive rinsing assembly 7, thereby improving water resource utilization and meeting energy conservation and environmental protection requirements.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
