Abstract
Description
Technical Field
[0001] The present invention relates to the field of marine environmental protection technology, and in particular to an integrated device for recycling and reusing marine plastic waste. Background Art
[0002] Marine plastic pollution has become a global ecological crisis. Approximately 8 million tons of plastic enter the ocean each year, accounting for over 80% of all marine debris. These plastics, driven by ocean currents, form five major garbage patches. Microplastics (<5mm) produced through ultraviolet degradation and mechanical wear have invaded the food chain, threatening over 700 species of marine life. Traditional governance models face three major bottlenecks:
[0003] 1. Manual salvage is inefficient, with the escape rate of small plastics exceeding 60%; 2. The cost of sorting plastics mixed with salt and biological attachments is high; 3. Ocean transportation leads to increased carbon emissions from recycling.
[0004] After searching, the marine plastic cleaning ship published with patent number CN113335463B includes a main body, which is a powered hull structure used for mobile operations on water. A load-bearing frame is provided on the main body. This marine plastic cleaning hull uses the main body designed with a powered hull structure as a carrier, and cooperates with the use of a belt conveying collection structure, a belt conveying cleaning structure and a power module to effectively realize the continuous mechanical collection and cleaning of marine plastic waste, facilitate the timely cleaning of marine plastic waste, effectively control marine water pollution, and ensure a good marine water environment. In addition, through the coordinated use of the provided drilling mechanism, rolling mechanism and connecting structure, it can simultaneously penetrate and roll the marine plastic waste to remove water during the continuous cleaning process, thereby reducing the weight of the plastic waste.
[0005] In actual application, the existing device still has some defects: due to the various shapes of plastics, for some lightweight plastics such as plastic bags, they are very easy to stick to the rolling mechanism when they are wet, and as the rolling mechanism moves, they are easy to get stuck in some gaps of the rolling mechanism, affecting normal operation; at the same time, when a large amount of plastic waste accumulates at the transmission entrance, it is easy to cause jamming, causing plastic waste (plastic bottles, etc.) to always linger at the transmission entrance and unable to enter the recycling device normally.
[0006] Therefore, the present invention proposes an integrated device for recycling and reusing marine plastic waste to solve the above problems. Summary of the Invention
[0007] To solve the above problems, the present invention provides an integrated device for the recovery and reuse of marine plastic waste. It uses an eccentric rotating mechanism to generate gas for cleaning the surface of the pressure roller while squeezing water out, thereby preventing some plastic from adhering to the surface of the pressure roller. At the same time, it physically intervenes (strikes) in areas on both sides of the feed end where plastic accumulation and jamming are likely to occur, so that the plastic in these areas can flow smoothly to a stable marine plastic waste collection area.
[0008] To achieve the above objectives, the technical solution of the present invention is as follows: an integrated marine plastic waste recovery and recycling device comprises a main body, with a control chamber, a melt granulation chamber, and a drying chamber disposed on the top of the main body from right to left, the melt granulation chamber being connected to a storage bin disposed on the top of the main body on one side, and a collection assembly for collecting and extruding marine plastic waste mounted on the top of the main body, with the outlet of the collection assembly located directly above the drying chamber;
[0009] The collecting assembly includes a fixed bracket, a conveyor belt and a pressure roller. The conveyor belt is installed on the fixed bracket. The fixed bracket is symmetrically provided with movable grooves. The two ends of the pressure roller extend into the movable grooves and are rotatably connected to the inner wall of the movable grooves. One end of the pressure roller is coaxially fixedly connected to a driving assembly arranged in the fixed bracket for driving the pressure roller to rotate. A rectangular frame is slidably fitted in the movable grooves. The rectangular frame is annularly sleeved on the pressure roller, and the surface of the pressure roller is always in contact with the inner wall of the rectangular frame. The central axis of rotation of the pressure roller is an eccentric axis.
[0010] The pressure roller is provided with an air transmission channel along the direction of its rotation center axis, and a number of air outlet holes are evenly provided on the surface of the pressure roller, and the air outlet holes are all connected to the air transmission channel; a first moving rod and a second moving rod are fixedly connected to both sides of the rectangular frame, and the first moving rod and the second moving rod are both slidably matched with the fixed bracket, and an air cavity corresponding to the first moving rod is provided in the fixed bracket, and a air transmission port connected to the air transmission channel is provided in the air cavity, and the second moving rod extends to the inlet end of the fixed bracket away from the rectangular frame and is fixedly connected to an auxiliary collection component for generating corresponding planar motion based on the reciprocating sliding of the second moving rod to disperse the marine plastic garbage stuck at the inlet end.
[0011] Principle of the basic solution: Through the eccentric rotation of the pressure roller, it pushes the rectangular frame to produce reciprocating horizontal sliding, so that the first moving rod performs piston motion in the air cavity, generating continuous gas, which flows to the air outlet through the gas transmission channel, and generates a continuous air flow layer on the surface of the pressure roller, which peels off some lightweight marine plastic waste from the pressure roller to prevent it from accumulating on the surface of the pressure roller and affecting subsequent garbage collection and recycling; at the same time, the second moving rod also slides horizontally back and forth with the rectangular frame, thereby driving the auxiliary collection component to perform curved motion, so that the auxiliary collection component can break up the areas on both sides of the inlet end of the fixed bracket where plastic waste is prone to accumulation and jamming, so that the plastic waste in these areas can quickly flow to the stable collection area (such as the middle position of the conveyor belt); after the collection is completed, these plastic wastes are made into new plastic particles through the drying bin and the melt granulation bin, and transported to the storage bin for storage.
[0012] The above solution has the following beneficial effects: 1. Compared with the existing technology, the innovative cleaning mechanism realizes dynamic anti-adhesion. The horizontal reciprocating motion of the rectangular frame is driven by the eccentric pressure roller, so that the first moving rod forms a piston effect in the air cavity, generating a continuous directional airflow that is evenly discharged through the surface of the pressure roller. This air flow layer forms a dynamic air film isolation during the rotation of the pressure roller, which can effectively peel off the electrostatic adsorption and physical adhesion generated by plastics of different materials during the extrusion process. Compared with the traditional scraper cleaning method, gas flushing not only avoids mechanical wear on the surface of the pressure roller, but its non-contact characteristics are more suitable for salty and humid marine environment conditions. At the same time, the two process links of drainage extrusion and surface cleaning are integrated into synchronous actions, which significantly improves the continuity of equipment operation.
[0013] 2. Bionic physical intervention ensures smooth feeding. The second moving rod converts horizontal reciprocating motion into a three-dimensional flapping action through a crank slider mechanism. Its motion trajectory simulates the mechanical characteristics of manual dredging operations. The auxiliary collection component forms a periodic flapping and plucking compound action on both sides of the feed end, forming a differentiated treatment for entangled fiber waste and irregular hard plastics: the flapping surface not only shakes off microplastic clusters without destroying the material shape, but also decomposes large entangled objects.
[0014] 3. Functional integration reconstructs the recycling process flow. Through spatial topology optimization, the four processes of collection, dehydration, drying, and granulation are vertically integrated, and the gravity potential energy of water generated by roller squeezing is used to achieve gravity-flow drying bin distribution. The shapes between each module.
[0015] Furthermore, the pressing roller is a triangular prism structure and the edges in the length direction are all rounded structures.
[0016] Beneficial effects: At the moment each edge contacts the material, the rounded structure reduces the impact load through progressive pressure applied by the arc surface, so that the lateral thrust exerted on the rectangular frame is always transmitted symmetrically along the horizontal axis, eliminating the deflection tendency of the frame during reciprocating motion. The rounded corners of the edges and the inner wall of the rectangular frame form a continuous sliding mating surface. When the pressure roller rotates, the rectangular frame is guided to move smoothly along the predetermined trajectory through geometric constraints, avoiding the motion vibration caused by the sudden change of the edges of the traditional polygonal structure. This symmetrical design enables the eccentric rotation energy to be efficiently converted into a pure linear reciprocating driving force. While enhancing the extrusion and dehydration efficiency, it guarantees the timing accuracy of the air chamber piston and the flapping mechanism, and ensures the coordinated stability of the dual systems of airflow cleaning and physical dredging.
[0017] Furthermore, the auxiliary collection components each include a movable groove symmetrically opened at the inlet end of the fixed bracket, one end of the second movable rod extends into the movable groove and is hinged to the first connecting rod, the first connecting rod is an L-shaped structure, the middle portion of the first connecting rod is rotatably connected to the inner wall of the movable groove, and the end of the first connecting rod away from the second movable rod is rotatably connected to the first roller;
[0018] A second connecting rod is rotatably connected inside the movable groove, and one end of the second connecting rod away from the first connecting rod is fixedly connected to a configuration block, and the other end of the second connecting rod is rotatably connected to the second roller; an arc-shaped guide rod is rotatably connected inside the movable groove, and the inner side wall of the arc-shaped guide rod is always in contact with the first roller and the second roller, and the first roller is always in contact with the side wall of the second connecting rod;
[0019] One end of each arc-shaped guide rod extends to the outside of the movable groove and is fixedly connected with a striking plate.
[0020] Beneficial Effects: This innovative structure creates a bionic dual-modal physical intervention mechanism, achieving intelligent anti-blocking through the geometric constraints of the kinematic pair. The reciprocating drive of the second movable rod is transmitted via an L-shaped connecting rod, causing the first roller to roll at variable speeds along the curved surface of the arc-shaped guide rod. This curved trajectory forces the striking plate to perform a compound motion of "slap-rebound-slide," physically dispersing plastic waste in areas prone to stuck plastic waste.
[0021] Furthermore, the striking plate has an L-shaped arc structure.
[0022] Beneficial Effects: The L-shaped arc structure forms a dual-modal mechanical transmission interface. Its curved surface curvature creates a centripetal convergence effect at the moment of contact, directing discrete plastics toward the bend of the striking plate for centralized processing. The L-shaped angle design creates a tangential force component during the rebound stroke, effectively stripping entangled fibers. The continuously changing curvature of the structure achieves a gradient attenuation of impact energy, enhancing dredging efficiency while preventing material splashing caused by rigid collisions.
[0023] Furthermore, a conversion rod is rotatably connected to the inlet end of the fixed bracket, a first combing plate is fixedly connected to the middle position of the conversion rod, a second combing plate is hinged to the bottom end of the first combing plate, and sliding grooves are opened on both side walls of the second combing plate, and the sliding grooves are slidably matched with linkage rods, and the linkage rods are fixedly connected to the corresponding striking plate at the end away from the second combing plate.
[0024] Beneficial effects: When the striking plate reciprocates, the linkage rod transmits the information through the slide groove to form the hinged swing of the second combing plate, so that the double combing plate combination produces a continuous action of "gathering-lifting-releasing", thereby pushing the garbage located in the center line area of the conveyor belt onto the conveyor belt, speeding up garbage recycling. At the same time, when pushing, there is a short-term shortage of garbage in the central area. Due to the flow characteristics of plastic garbage in the ocean, the garbage around the fixed bracket quickly gathers to this area. It can also make the garbage in the areas on both sides that are prone to garbage accumulation and jamming and difficult to recycle flow to this area, reducing the possibility of plastic garbage jamming in these areas.
[0025] Furthermore, the first combing plate and the second combing plate are both arc-shaped structures with the centers facing the fixed bracket.
[0026] Beneficial Effects: The curved dual combing plates create a radial flow field, with their concentric arc curvature forming a tapering guide channel. The static curved surface of the first combing plate and the dynamic curved surface of the second combing plate maintain a continuous curvature connection during their swing, ensuring that discrete plastics always slide and converge along a tangential direction. The center-of-center orientation design ensures that the comb teeth's trajectory forms a golden angle with the conveyor belt's centerline. When the striking plate retracts, the vortex effect created by the second combing plate's changing elevation angle draws marginal material into the main channel, eliminating blind spots on either side.
[0027] Furthermore, a plurality of through holes are opened on the surface of the second carding plate.
[0028] Beneficial effects: The design of the through-holes reduces the water flow resistance while the hole array induces local turbulence when the second combing plate swings, accelerating the rupture of the water film on the surface of fibrous garbage; the Venturi effect generated by water flowing through the through-holes absorbs microplastics from the gaps between the comb teeth, avoiding pore blockage.
[0029] Furthermore, a propeller is provided at the bottom of the main body.
[0030] Beneficial effect: The axial thrust generated by the rotation of the blades works synergistically with the circumferential eddy field, which not only enables the device to navigate autonomously in the ocean current environment, but also guides the discrete plastic waste to the entrance of the fixed bracket by inducing water flow.
[0031] Furthermore, the driving assembly includes a motor arranged inside the fixing bracket.
[0032] Beneficial effect: Provides eccentric rotation driving force for the pressure roller to complete subsequent actions.
[0033] Furthermore, a balancing channel communicating with the outside is opened in each air cavity, and a one-way valve is installed in each balancing channel.
[0034] Beneficial effect: When the first moving rod returns, the one-way valve opens to inhale dry air to compensate for the cavity pressure and eliminate negative pressure blockage; during the forward stroke, the valve body closes to maintain the directional output of high-pressure airflow.
[0035] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0043] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0045] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0046] The following is further described in detail through specific implementation methods:
[0047] Example 1:
[0048] As attached Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown: An integrated device for recycling and reusing marine plastic waste, comprising a main body 1, a propeller 20 (such as Figure 2 As shown), the top of the main body 1 is provided with a control chamber 3, a melting granulation bin 4 and a drying bin 5 from right to left (as shown). Figure 1 (As shown), one side of the melt granulation bin 4 is connected to the storage bin 2 located on the top of the main body 1. A collection assembly for collecting and extruding marine plastic waste is installed on the top of the main body 1, with the collection assembly outlet located directly above the drying bin 5. The propeller 20 ensures stable and controllable navigation of the device in the ocean, while also inducing a certain amount of induction effect on the surrounding ocean currents, inducing the water flow to converge the dispersed plastic waste towards the collection assembly, indirectly improving the cleaning and recovery efficiency of marine plastic waste.
[0049] At the same time, after completing the recycling of marine plastics, the plastic waste is sequentially placed in the drying bin 5, the melting granulation bin 4 and the storage bin 2 (these processes are all completed using existing technologies, for example: in the hot air circulation heating melting granulation process, the hot air circulation system formed by the centrifugal fan and the heating tube is used to dry and heat the material; the plastic melting granulation device realizes continuous melting and pelletizing by optimizing the screw structure and the melting cavity design), that is, the drying - decomposition melting granulation - storage for standby of the recycled plastic waste is completed, completing the integrated processing of the recycling and reuse of the entire marine plastic waste.
[0050] However, during the recycling phase of marine plastic waste, pre-processing is usually performed. For example, the plastic waste is squeezed to remove excess water and reduce its volume, thereby increasing the amount of plastic waste that can be processed in a single operation in subsequent processes. However, some existing devices use a rolling mechanism to squeeze the plastic waste. Due to the light weight (small volume), some plastic waste is easily attached to the rolling mechanism in the presence of water. As the rolling mechanism moves, it is easy for the plastic waste to get stuck in some gaps of the rolling mechanism, affecting normal operation.
[0051] In this solution, specifically, the collecting assembly includes a fixed bracket 6, a conveyor belt and a pressure roller 7. The conveyor belt is installed on the fixed bracket 6. The fixed bracket 6 is symmetrically provided with movable grooves. Both ends of the pressure roller 7 extend into the movable grooves and are rotatably connected to the inner wall of the movable groove. One end of the pressure roller 7 is connected to a motor arranged inside the fixed bracket 6 by a coaxial coupling.
[0052] A rectangular frame 8 is slidably fitted in the movable groove. The rectangular frame 8 is annularly sleeved on the pressure roller 7 and the surface of the pressure roller 7 is always in contact with the inner wall of the rectangular frame 8. The central axis of rotation of the pressure roller 7 is an eccentric axis. The pressure roller 7 is a triangular prism structure and the edges in the length direction are all rounded structures.
[0053] The pressure roller 7 is provided with an air supply channel 701 along its central axis of rotation, and a plurality of air outlet holes 702 are evenly provided on the surface of the pressure roller 7, and the air outlet holes 702 are all connected to the air supply channel 701; a first movable rod 802 and a second movable rod 801 are fixedly connected to both sides of the rectangular frame 8, respectively, and the first movable rod 802 and the second movable rod 801 are slidably matched with the fixed bracket 6, and an air cavity 803 corresponding to the first movable rod 802 is provided in the fixed bracket 6, and a gas supply port 804 connected to the air supply channel 701 is provided in the air cavity 803, and a balancing channel connected to the outside is provided in the air cavity 803, and a one-way valve is installed in the balancing channel to ensure the stability of the air pressure inside the air cavity 803 when the first movable rod 802 performs piston motion in the air cavity 803, thereby providing stable and continuous high-pressure gas when the first movable rod 802 squeezes the gas in the air cavity 803.
[0054] Specifically, the motor drives the triangular prism pressure roller 7 to rotate around the eccentric axis through the coupling. Since there is an eccentricity between the geometric center of the pressure roller 7 and the center axis of rotation, its outer contour produces periodic radial displacement during rotation. When the rounded edges of the triangular prism contact the wet plastic garbage on the conveyor belt, they gradually apply pressure through the arc surface, forming an "extrusion-release" cycle, that is, completing the preliminary extrusion and drainage of marine plastic garbage. At the same time, the eccentric rotation of the pressure roller 7 forces the rectangular frame 8 mounted on the outside to slide back and forth horizontally along the moving groove: when the long edge surface (maximum eccentric position) of the pressure roller 7 contacts the conveyor belt, the frame is pushed to the extreme position on one side; when the short edge surface (minimum eccentric position) contacts, it slides back in the opposite direction, and the sliding stroke is performed by the rigidly connected first moving rod 802 in the air cavity 803 as a piston motion: Compression stroke: the first moving rod 802 compresses the air in the air cavity 803 (such as Figure 5 As shown, the airflow enters the axial air delivery channel 701 of the pressure roller 7 through the air delivery port 804 and is ultimately ejected at high speed from the surface air outlet 702, forming a dynamic air film isolation layer that quickly removes the plastic adhering to the surface of the pressure roller 7. During the retraction stroke, when the first moving rod 802 moves left, the air cavity 803 is rapidly replenished with air through the one-way valve to maintain airflow continuity. This simultaneously drives the second moving rod 801 to perform reciprocating horizontal motion.
[0055] Example 2:
[0056] The difference from the above embodiment is that, Figure 1 、 Figure 4 and Figure 6 As shown, when actually recycling marine garbage, blind spots are easily formed on both sides of the inner wall of the inlet end of the fixed bracket 6, causing marine plastics to accumulate in these areas and unable to be normally recovered into the drying bin 5 through the conveyor belt. Therefore, the second movable rod 801 extends to the inlet end of the fixed bracket 6 at one end away from the rectangular frame 8 and is fixedly connected to an auxiliary collection component for generating corresponding planar movement based on the reciprocating sliding of the second movable rod 801 to break up the marine plastic garbage stuck at the inlet end. The auxiliary collection components include movable grooves symmetrically opened at the inlet end of the fixed bracket 6, one end of the second movable rod 801 extends into the movable groove and is hinged to a first connecting rod 15, which is an L-shaped structure. The middle part of the first connecting rod 15 is rotatably connected to the inner wall of the movable groove, and the end of the first connecting rod 15 away from the second movable rod 801 is rotatably connected to the first roller 16;
[0057] The movable groove is rotatably connected to a second connecting rod 18, and the end of the second connecting rod 18 away from the first connecting rod 15 is fixedly connected to a configuration block 19, and the other end of the second connecting rod 18 is rotatably connected to a second roller 17; the movable groove is rotatably connected to an arc-shaped guide rod 10, and the inner side walls of the arc-shaped guide rod 10 are always in contact with the first roller 16 and the second roller 17, and the first roller 16 is always in contact with the side wall of the second connecting rod 18; one end of the arc-shaped guide rod 10 extends to the outside of the movable groove and is fixedly connected to a striking plate 11, which is an L-shaped arc structure. The L-shaped structure increases the slapping area, and elastic material can be used at the L-shaped corner.
[0058] The specific implementation process is as follows: As described in Example 1, when the second movable rod 801 rotates eccentrically with the pressure roller 7 to slide back and forth horizontally, it drives the hinged L-shaped first connecting rod 15 to swing around the rotation fulcrum of the inner wall of the movable groove. When the second movable rod 801 slides outward (toward the inlet end), the short arm of the first connecting rod 15 is pulled, and the first roller 16 connected to the end of the long arm rolls along the inner wall of the arc-shaped guide rod 10, while pushing the second connecting rod 18 to deflect around the rotation fulcrum in the movable groove, and because the rolling trajectory of the first roller 16 is constrained by the curved surface of the arc-shaped guide rod 10, the second connecting rod 18 is forced to produce an asymmetric angular displacement. Therefore, when the second movable rod 801 is pushed outward, the first roller 16 rolls along the inner curved surface of the arc-shaped guide rod 10 (as shown in FIG. Figure 4 As shown in FIG, the second connecting rod 18 is synchronously driven to rotate rapidly (i.e., the first roller 16 presses the side wall of the second connecting rod 18), causing the second roller 17 on the second connecting rod 18 to roll rapidly along the flat inner surface of the arc-shaped guide rod 10. At this time, the configuration block 19 is lifted upward, and the weight of the configuration block 19 is used to keep the second roller 17 in contact with the inner surface of the arc-shaped guide rod 10. Due to the curved design of the arc-shaped guide rod 10, the striking plate 11 is guided in the convex direction of the L-shaped arc surface, and strikes the deposits on the side wall of the inlet end at high speed along the tangential direction.
[0059] When the second movable rod 801 retracts, the first roller 16 rolls in the opposite direction along the inner curved surface of the guide rod, and the second connecting rod 18 is quickly reset by the gravity of the configuration block 19 (at this time, the configuration block 19 moves downward), and the striking plate 11 is separated from the material by the elastic deformation at the L-shaped corner, avoiding pulling the loose plastic.
[0060] That is, when new deposits first appear in the blind area, the striking plate 11 is just at the maximum acceleration impact position, breaking up the plastic waste in these areas and facilitating their flow into the normal recycling area of the conveyor belt.
[0061] Example 3:
[0062] The difference from the above embodiment is that, Figure 1 and Figure 4As shown, the inlet end of the fixed bracket 6 is rotatably connected to the conversion rod 9, the middle position of the conversion rod 9 is fixedly connected to the first combing plate 14, the bottom end of the first combing plate 14 is hinged to the second combing plate 13, and the second combing plate 13 has sliding grooves on both side walls, and the sliding grooves are slidably matched with the linkage rod 12, and the linkage rod 12 is fixedly connected to the corresponding striking plate 11 at the end away from the second combing plate 13.
[0063] The first combing plate 14 and the second combing plate 13 are both arc-shaped structures with the center of the circle facing the fixed bracket 6. A plurality of through holes are opened on the surface of the second combing plate 13 to reduce the resistance of the second combing plate 13 when it swings in water.
[0064] The specific implementation process is as follows: when the striking plate 11 is driven by the arc-shaped guide rod to hit outward, the linkage rod 12 fixed on the side where the two striking plates 11 are close to each other slides along the slide groove of the second combing plate 13, pulling the second combing plate 13 to swing around its top hinge point, pushing the plastic waste onto the conveyor belt. When the striking plate 11 performs a striking action, the first combing plate 14 rotates counterclockwise. At this time, the second combing plate 13 rotates clockwise around the hinge point, and the angle between the first combing plate 14 and the second combing plate 13 increases. At the same time, the bottom of the second combing plate 13 gradually approaches the plastic garbage on the sea surface. Then, when the striking plate 11 completes the striking and resetting, the first combing plate 14 rotates clockwise and the second combing plate 13 rotates counterclockwise, and the angle between the two decreases. During the folding process of the first combing plate 14 and the second combing plate 13, the motion trajectory of the bottom of the second combing plate 13 is used to push the marine plastic garbage in the ocean current onto the conveyor belt, thereby improving the recycling efficiency. At the same time, the center of the double arc surface is oriented to generate a centripetal convergence effect when the two swing, and the edge plastic garbage is guided to the middle of the conveyor belt. In conjunction with the peak period of the striking of the striking plate 11, the scattered marine plastic garbage (edge blind area) is immediately allowed to enter the high-speed flow channel.
[0065] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
