Abstract
Description
Technical Field
[0001] This invention belongs to the field of marine ecological restoration technology, and more specifically, it relates to a transplantation device and method suitable for the ecological restoration of seagrass beds. Background Technology
[0002] Transplantation, seeding, and habitat restoration are the main methods for the ecological protection and restoration of seagrass beds, with transplantation being the most widely practiced. Transplantation involves preparing seagrass seedlings or rhizomes collected from existing seabeds into transplantation units, which are then planted manually or mechanically in the restoration area. The aim is to achieve large-scale seagrass bed restoration through the propagation and proliferation of the seagrass itself. Currently, there are two major challenges with transplantation technology: first, it is difficult to fix the transplanted units to the seabed, and they are easily washed away by waves, a significant reason for the low success rate of transplanted seedlings; second, there is a lack of automated equipment, with most operations relying on manual planting of seedlings one bundle at a time. This method is subject to many limitations, resulting in low efficiency, high costs, and hindering large-scale seagrass bed ecological protection and restoration. Summary of the Invention

The front end of the second guide base plate (8) is welded to the lower end or the rear end of the first guide base plate (7), and the two sides of the second guide base plate (8) are vertically welded with second frame side plates. (12); The first frame side plate (10) and the second frame side plate (12) are basically at the same height, and the first frame side plate (10) and the second frame side plate (12) are welded at the junction; Two first guide side plates (11) are symmetrically welded in the first guide base plate (7) about the center line of the guide direction (from the front end to the rear end). The two first guide side plates (11) are located in the middle and rear part of the first guide base plate (7). The first guide groove formed between the two first guide side plates (11) is trumpet-shaped at the entrance and gradually narrows along the guide direction; Two second guide side plates (13) are symmetrically and vertically welded in the second guide base plate (8) about the center line of the guide direction. The second guide groove formed between the two second guide side plates (13) is trumpet-shaped at the entrance and then equal in width. The rear end of the first guide side plate (11) and the front end of the second guide side plate (13) are welded at the junction;
[0008] Preferably, the seedling rope transplanting structure includes a plow blade assembly (14), a soil covering structure (15), and a compaction wheel (16); the plow blade assembly (14) is welded together from five vertical sheet-like structures, and its horizontal cross-sectional top view along the transplanting direction (consistent with the guiding direction, from the front end to the rear end) is a double fork structure composed of sheet-like cutters and C-shaped openings. The blade is in front, and the C-shaped opening is behind. The angle between the two forked branches corresponding to the C-shaped opening is about 60°, and they are symmetrical about the center line. The soil covering structure (15) follows the C-shaped opening of the plow assembly (14) and consists of two vertical blade structures at an angle of about 30° to the direction of transplanting. The two blade structures are symmetrical about the center line of the direction of transplanting. The horizontal distance between the two blade structures is the width of the opening of the soil covering structure (15), which is wider at the front and narrower at the back. The width of the rear end is basically the same as the width of the end of the C-shaped opening of the plow assembly. The plow assembly (14) and the soil covering structure (15) are located in the middle and rear part below the second guide plate (8). 14) The top surfaces of the sheet-like structures corresponding to the soil covering structure (15) are all welded or fixedly connected to the second guide base plate (8) and arranged symmetrically about the center line of the second guide base plate (8); the plow blade assembly (14) is located in the projection below the second guide groove, and the width of the second guide groove formed between the two second guide side plates (13) is consistent with the width of the C-shaped opening of the plow blade assembly (14), and the soil covering structure (15) is located outside the projection below the second guide groove; the bottom plate of the second guide groove has a channel, the front end of the channel is consistent with the top and bottom of the C-shaped opening corresponding to the plow blade assembly (14), and the rear end of the channel extends to the second guide. At the tail end of the base plate (8), the width of the channel is consistent with the width of the second guide groove (that is, the base plate of the second guide groove is also cut off at the rear end of the top surface welding line of the plow blade assembly (14) and along the inner side of the top surface welding line of the double fork branch until the tail end of the second guide base plate (8). The channel makes the second guide groove form a hole in the base plate after the C-shaped opening of the plow blade assembly (14), thereby forming a seedling rope transplanting channel; the compaction wheel (16) is two solid wheels or counterweight wheels with a gravity greater than buoyancy, symmetrically arranged about the center line of the transplanting direction, with the upper part of the two wheels tilted outward and the angle with the vertical plane is about 10 degrees. °, the net width between the inner end faces of the two wheels is basically the same as the width of the rear end of the soil covering structure (15); a first short shaft (17) is fixedly suspended on the outer side of the tail end of the two second frame side plates (12) respectively, the two first short shafts (17) are respectively hinged to the front end of a second connecting plate (18), the tail ends of the two second connecting plates (18) are respectively hinged to the outer end of a second short shaft (19), the inner ends of the two second short shafts (19) are respectively connected to the wheel core of the two compaction wheels (16) through axle pins, and the space required for the seedling rope transplanting channel is reserved between the inner end faces of the two compaction wheels (16);
[0009] Preferably, the main structural components of the transplanting device are made of a material with a specific gravity greater than seawater to ensure that the device can work in close contact with the seabed surface by its own weight. The seedling rope comes from seedling trays made and prepared on-site or prefabricated or artificially planted seedling trays (20). Multiple seaweed transplanting units (21) connected by ropes (22) are placed in the seedling trays (20). The multiple seaweed transplanting units (21) are evenly spaced and connected in series along the length of the ropes (22). The seaweed transplanting units (21) can be individual artificial seaweed seedlings or bundles of weighted transplanting seedlings. Multiple seaweed transplanting units (21) are connected together by ropes (22). Each seaweed transplanting unit can be a single artificial seaweed seedling or a bundle of weighted transplanting seedlings. The bottom of the upright vertical seedling tray (20) of unit (21) has a rope (22) with the spacing between two adjacent transplanting units along the length of the rope (22) determined according to the required transplanting density. The rope (22) carrying the seaweed transplanting unit (21) is arranged in a bent S-shape within the seedling tray (20). The width of the rope (22) can be adjusted to allow the seaweed transplanting unit (21) to be moved from lying flat to upright during transport. The upper opening width of the aforementioned first guide plate (7) depends on the width of the seedling tray or the requirements on site. The entrance width of the funnel-shaped opening of the first guide groove formed between the first guide side plates (11) is approximately the height of the seaweed seedling of the transplanting unit, gradually narrowing along the guide direction. At the entrance of the second guide groove flare, the entrance width of the second guide groove flare is slightly larger than the width of the second guide groove, while the width of the second guide groove is equal to the width of the C-shaped opening of the plow assembly (14). The width of the C-shaped opening of the plow assembly (14) is about 1-2 cm larger than the diameter of the seaweed artificial seedling unit or the counterweight transplant bundle unit on the seedling rope. The heights of the first guide side plate (11) and the second guide side plate (13) are basically equal and slightly lower than the height of the seaweed seedling of the transplant unit. The heights of the first frame side plate (10) and the second frame side plate (12) are basically equal and slightly higher than the height of the seaweed seedling of the transplant unit. Along the guide direction, the length of the first guide groove flare in front of the first guide bottom plate (7) is... The length of the first guide groove, the length of the second guide groove before the bottom plate perforation, and the length of the seaweed seedling rope transplanting channel from the bottom plate perforation to the compaction wheel are all approximately the length of the seedling rope for 3-4 transplanting units on the seedling rope. Taking the bottom surface of the first traveling wheel (5) in contact with the seabed as the reference surface, the bottom of each vertical sheet structure of the plow assembly (14) is 3-5cm deeper than the reference surface, that is, the transplanting depth of the seaweed transplanting unit is 3-5cm. The bottom surface of the two vertical sheet structures of the soil covering structure (15) is 0.5-1cm deeper than the reference surface. The contact line between the bottom of the outer end face of the two compaction wheels (16) and the seabed is basically flush with the reference surface.
[0010] Preferably, when using the aforementioned seaweed seedling rope transplanting device for seaweed seedling rope transplanting operations, it can be carried out manually or by towing using boats, rafts, etc., as detailed below:
[0011] When manual operation is used, a human-assisted walking structure is added. Preferably, the human-assisted walking structure includes a seedling tray support (23), a fourth horizontal axis (24), a fifth horizontal axis (25), two second walking wheels (26), two third connecting plates (27), and a manual handrail (28). The seedling tray support (23) is a grid-shaped fixed frame structure, with its upper edge fixed on the fifth horizontal axis (25) and its lower edge fixed on the second horizontal axis (2). It is arranged at an inclination, with the inclination direction and angle the same as the first guide base plate (7). Its width is also the same as the opening at the upper end of the first guide base plate (7), and its length depends on the length of the seedling tray placed on it. The horizontal direction of the fourth horizontal axis (24) and the fifth horizontal axis (25) is parallel to the first horizontal axis (1) and the second horizontal axis (26). 2) The third horizontal axis (3), the fourth horizontal axis (24), the fifth horizontal axis (25), and the handrail (28) are arranged from bottom to top to form a vertical or slightly inclined plane. The lower end of the handrail (28) is fixed on the fifth horizontal axis (25). The two ends of the fifth horizontal axis (25) are fixedly connected to the upper ends of the two third connecting plates (27) respectively. The lower ends of the two third connecting plates (27) are fixedly connected to the two ends of the fourth horizontal axis (24) respectively. Two second traveling wheels (26) are connected to the fourth horizontal axis (24) through bearings. The two second traveling wheels (26) are symmetrically arranged about the vertical center line of the fourth horizontal axis (24). The bottom surface of the two second traveling wheels (26) is in contact with the seabed surface and is at the same height as the bottom surface of the first traveling wheel (5).
[0012] When manual labor is used, the preferred work steps are as follows:
[0013] The first step is to place the seedling tray (20) on the seedling tray support (23), arrange the seedling ropes in the seedling tray, arrange the transplanting units vertically and orderly, and loosen the bottom of the transplanting units so that the seedling ropes can be easily dragged away from the seedling tray in subsequent operations.
[0014] The second step is to open the initial rope end of the seedling rope and manually drag the rope end down the inclined surface of the first guide plate (7). The rope end drags the transplanting unit on the subsequent seedling rope through the upper surface of the first guide plate (7), the lower part of the first guide roller (6), the first guide groove and the second guide groove in sequence. The posture of the transplanting unit also changes from upright in the seedling tray to lying flat on the surface of the first guide plate (7). Then, under the action of the first guide groove, it slowly stands up from lying flat until it becomes completely upright under the action of the second guide groove. Finally, it falls into the seedling rope transplanting channel with the bottom plate open. Use bamboo forks or bamboo nails to fix the aforementioned rope end to the bottom seabed in the space of the seedling rope transplanting channel, and gently press down the second guide plate (8) so that the plow assembly (14) and the soil covering structure (15) are inserted into the seabed.
[0015] The third step involves manually holding the upper end of the handrail (28) and dragging the human-assisted walking mechanism forward in a backward posture. Since the seedling tray support (23) on the human-assisted walking mechanism is fixedly connected to the second horizontal axis (2) of the aforementioned seaweed seedling rope transplanting device, the seaweed seedling rope transplanting device is dragged forward. During the forward movement of the seedling rope transplanting device, the plow blade assembly (14) welded to the bottom surface of the second guide plate (8) creates a C-shaped groove. Because the seedling rope end has been fixed to the seabed, the subsequent transplanting unit is placed in the transplanting device... As the plant moves forward, it passes through the perforated bottom plate and falls into the C-shaped trench. The soil covering structure (15) after the plow assembly (14) gathers the mud and sand on both sides of the C-shaped trench towards the center, fills the trench and covers the roots of the transplanting unit. At the same time, the compaction wheel (16) compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the net space of the reserved transplanting channel. Thus, the transplanting units on the seedling rope are transplanted into the seabed in sequence. The transplanting depth is the trenching depth of the plow assembly (14), which is 3-5 cm.
[0016] When using a hull or raft for towing operations, preferably, two additional towing links (33) are provided. A third short shaft (29) is fixedly suspended from the outer edge of each side of the hull or raft. The other end of the third short shaft (29) is fixedly connected to one end of each of the two fourth connecting plates (30). A sixth horizontal shaft (31) is provided, with both ends fixedly connected to the other ends of the two fourth connecting plates (30). A rotatable second guide roller (32) is provided on the sixth horizontal shaft (31). The two towing links (33) The length direction is arranged parallel and symmetrical about the center line of the seaweed transplanting device in the transplanting direction. One end of each of the two towing links (33) is hinged to the two ends of the sixth horizontal axis, and the other end is hinged to the second horizontal axis (2) of the seaweed transplanting device. When the depth of the hull or the raft from the seabed surface decreases or increases, it drives the angle between the two towing links (33) and the horizontal plane to decrease or increase, and drags the seaweed transplanting device to a greater or lesser distance from the hull or the raft, so as to adapt to the changing operational needs of the sea level and water depth.
[0017] When using a hull or raft for towing operations, the preferred operation steps are as follows:
[0018] The first step is to place the seedling tray (20) on the hull or the deck of the raft, arrange the seedling ropes in the seedling tray, make the transplanting units stand upright and orderly, and loosen the bottom of the transplanting units so that the seedling ropes can be easily dragged away from the seedling tray in subsequent operations.
[0019] The second step is to open the initial rope end of the seedling rope and manually drag the rope end down along the inclined surface of the dragging link (33) and the first guide plate (7). The rope end drags the transplanting unit on the subsequent seedling rope through the upper surface of the second guide roller (32), the space between the dragging link (33), the upper surface of the first guide plate (7), the lower part of the first guide roller (6), the first guide groove and the second guide groove. The posture of the transplanting unit also changes from vertical in the seedling tray to lying flat on the surface of the first guide plate (7). Then, under the action of the first guide groove, it slowly stands up from lying flat until it becomes completely upright under the action of the second guide groove. Finally, it falls into the seedling rope transplanting channel with the bottom plate open. Use bamboo forks or bamboo nails to fix the aforementioned rope end to the bottom seabed in the seedling rope transplanting channel space, and gently press down the second guide plate (8) so that the plow assembly (14) and the soil covering structure (15) are inserted into the seabed.
[0020] The third step involves starting the hull or raft forward and dragging the connecting rod (33) forward. Since the dragging connecting rod (33) is hinged to the second horizontal axis (2) of the aforementioned seaweed seedling rope transplanting device, it drags the seaweed seedling rope transplanting device forward. Because the weight of the seaweed seedling rope transplanting device exceeds its buoyancy, the first traveling wheel (5) of the transplanting device will always travel close to the seabed surface. During the forward movement of the seedling rope transplanting device, the plow blade assembly (14) welded to the bottom surface of the second guide plate (8) creates a C-shaped groove. Since the seedling rope end has been fixed to the seabed, subsequent... As the transplanting device moves forward, the transplanting units pass through the perforated bottom plate and fall into the C-shaped trench. The soil covering structure (15) after the plow assembly (14) gathers the mud and sand on both sides of the C-shaped trench towards the center, filling the trench and covering the roots of the transplanting units. At the same time, the compaction wheel (16) compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the net space of the pre-reserved transplanting channel. Thus, the transplanting units on the seedling rope are transplanted into the seabed in sequence. The transplanting depth is the trenching depth of the plow assembly (14), which is 3-5 cm.
[0021] The beneficial effects of adopting the above technical solution are as follows:
[0022] 1. Use ropes as a carrier medium for seagrass seedlings or mature transplant bundles to prevent seagrass seedlings from being lost due to wave erosion, and facilitate mechanized or large-scale automated operations.
[0023] 2. A seaweed seedling rope transplanting device, which has a simple structure, low cost, and is easy to operate, greatly reducing labor intensity while ensuring standardized operation and improving the transplanting seedling survival rate;
[0024] 3. A seaweed seedling rope transplanting device can be used for both manual assisted operation and large-scale automated operation using a ship or raft. The latter can adapt to the operation requirements of different water depths, has high operation efficiency, and strong adaptability to marine conditions. Attached Figure Description

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0035] like Figure 1-4As shown, a seaweed seedling rope transplanting device includes three parts: a support and walking structure, a seedling rope guide frame structure, and a seedling rope transplanting structure.
[0036] The supporting walking structure includes a first horizontal axis (1), a second horizontal axis (2), and a third horizontal axis (3). The three horizontal axes are of roughly equal length and are arranged sequentially from bottom to top to form a vertical plane. Two first connecting plates (4) are symmetrically arranged about the vertical center lines of the three horizontal axes. The two ends of the three horizontal axes are rigidly connected to the low, middle, and high ends of one of the first connecting plates (4) respectively to form a supporting structure frame. Two first walking wheels (5) are connected to the first horizontal axis (1) through bearings. The two first walking wheels (5) are symmetrically arranged about the vertical center line of the first horizontal axis (1) and can walk on the seabed surface. At the same time, the bottom surface of the first walking wheel (5) in contact with the seabed is the reference surface for the planting depth. A first seedling rope and a first guide roller (6) that can rotate are arranged on the third horizontal axis (3).
[0037] The seedling rope guide frame structure includes a first guide base plate (7) and a second guide base plate (8). The first guide base plate (7) is arranged diagonally downwards at an angle of about 15° to the horizontal plane. It is wider at the top and narrower at the bottom, with an opening at the higher end and the lower end welded to one end of the second guide base plate (8). The first frame side plates (10) are vertically welded on both sides, and the bottom surface near the higher end is slotted (9) and clamped onto the aforementioned second horizontal axis (2), and spot-welded for fixed connection. The second guide base plate (8) is arranged horizontally, with the same width as the lower end of the first guide base plate (7). One end is welded to the lower end of the first guide base plate (7), and the other end is... The opening is vertically welded with second frame side plates (12) on both sides; (10) and (12) are basically the same height and are welded at the connection; two first guide side plates (11) are vertically welded symmetrically about the center line of the guide direction in the first guide base plate (7), and the first guide groove formed between the two first guide side plates (11) is horn-shaped at the entrance and gradually narrows along the guide direction; two second guide side plates (13) are vertically welded symmetrically about the center line of the guide direction in the second guide base plate (8), and the second guide groove formed between the two second guide side plates (13) is horn-shaped at the entrance and then equal in width;
[0038] The seedling rope transplanting structure includes a plow blade assembly (14), a soil covering structure (15), and a compaction wheel (16); the plow blade assembly (14) is welded together from five vertical plate-like structures, and its horizontal cross-sectional top view is a double fork structure along the transplanting direction. The blade is in front, with a C-shaped opening behind, and the two forked branches have an angle of about 60°, symmetrical about the center line; the soil covering structure (15) follows the C-shaped opening of the plow assembly (14), and consists of two vertical blade-like structures at an angle of about 30° to the direction of transplanting. The two blade-like structures are symmetrical about the center line of the direction of transplanting. The horizontal distance between the two blade-like structures is the width of the opening of the soil covering structure (15), which is wider at the front and narrower at the back. The width of the rear end is basically the same as the width of the end of the C-shaped opening of the plow; the compaction wheel (16) Two solid wheels or counterweight wheels with a gravity greater than buoyancy are arranged symmetrically about the center line of the rice planting direction. The upper parts of the two wheels are inclined outward and the angle between them and the vertical plane is about 10°. The width between the lower end faces is basically the same as the width of the rear end of the soil covering structure (15). The top surfaces of the plow blade assembly (14) and the sheet structure of the soil covering structure (15) are welded or fixedly connected to the bottom surface of the second guide plate (8), located in the middle and rear part of the second guide plate (8), and about the center of the second guide plate (8). The arrangement is symmetrical; the width of the second guide groove formed between the two second guide side plates (13) is consistent with the width of the C-shaped opening of the plow blade assembly (14). The bottom plate of the second guide groove is also cut off at the rear end of the top surface welding line of the plow blade assembly (14) and along the inner side of the top surface welding line of the double fork branch, until the tail end of the second guide bottom plate (8), so that the second guide groove forms a seedling rope transplanting channel with a hole in the bottom plate after the starting position of the C-shaped opening of the plow blade assembly (14); in the aforementioned two... A first short shaft (17) is fixedly suspended from the outer side of the tail end of the two frame side plates (12). The other ends of the two first short shafts (17) are respectively hinged to the front end of the second connecting plate (18). The tail ends of the two second connecting plates (18) are respectively hinged to the outer ends of the two second short shafts (19). The inner ends of the two second short shafts (19) are respectively connected to the wheel core of the two compaction wheels (16) through axle pins. The inner end faces of the two compaction wheels (16) are reserved to provide the clearance required for the seedling rope transplanting channel.
[0039] The main structural components of the seaweed seedling rope transplanting device are made of a material with a specific gravity greater than that of seawater to ensure that the device can work in close contact with the seabed surface by its own weight. The seedling rope comes from seedling trays made and sorted on site or prefabricated or artificial seedling trays (20). The seaweed transplanting units (21) on the seedling rope can be artificial seaweed seedling units or counterweight transplanting bundle units. Each transplanting unit is connected by a rope (22). The spacing between each transplanting unit on the seedling rope is determined according to the required transplanting density. The upper opening width of the aforementioned first guide bottom plate (7) depends on the width of the seedling tray or the requirements on site. The entrance width of the first guide groove funnel formed between the first guide side plates (11) is approximately the height of the seaweed seedling of the transplanting unit. It gradually narrows along the guide direction until the entrance of the second guide groove funnel. The entrance width of the second guide groove funnel is slightly larger than the width of the second guide groove. The width of the second guide groove is equal to the C-shaped opening width of the plow assembly (14). The C-shaped opening width of the plow assembly (14) is larger than the seaweed artificial seedling unit or counterweight transplanting bundle unit on the seedling rope. The diameter of the seedling is about 1-2 cm. The height of the first guide side plate (11) and the second guide side plate (13) is basically the same, slightly lower than the height of the seaweed seedling in the transplanting unit. The height of the first frame side plate (10) and the second frame side plate (12) is basically the same, slightly higher than the height of the seaweed seedling in the transplanting unit. Along the guiding direction, the length of the first guide groove before the flared opening above the first guide bottom plate (7), the length of the first guide groove, the length of the second guide groove before the bottom plate is hollowed out, and the length of the seaweed seedling rope transplanting channel after the bottom plate is hollowed out up to the compaction wheel. The lengths are approximately the lengths of 3-4 transplanting units on the seedling rope; taking the bottom surface of the first traveling wheel (5) in contact with the seabed as the reference surface, the bottom surface of each vertical sheet structure of the plow assembly (14) is 3-5cm deeper than the reference surface, that is, the transplanting depth of the seagrass transplanting unit is 3-5cm, the bottom surface of the two vertical sheet structures of the soil covering structure (15) is 0.5-1cm deeper than the reference surface, and the contact line between the bottom of the outer end face of the two compaction wheels (16) and the seabed is basically flush with the reference surface;
[0040] When using the aforementioned seaweed seedling rope transplanting device for seaweed seedling rope transplanting operations, both manual labor and towing operations using boats, rafts, etc., can be employed, as detailed below:
[0041] According to the diagram Figure 5-6When manual operation is used, a human-assisted walking structure is added. The human-assisted walking structure includes a seedling tray support (23), a fourth horizontal axis (24), a fifth horizontal axis (25), two second walking wheels (26), two third connecting plates (27), and a manual handrail (28). The seedling tray support (23) is a grid-shaped fixed frame structure. Its upper edge is fixed on the fifth horizontal axis (25), and its lower edge is fixed on the second horizontal axis (2). It is arranged at an angle, with the same tilt direction and angle as the first guide base plate (7). Its width is also the same as the opening at the upper end of the first guide base plate (7), and its length depends on the length of the seedling tray placed on it. The horizontal direction of the fourth horizontal axis (24) and the fifth horizontal axis (25) is parallel to the first horizontal axis (1) and the second horizontal axis (26). 2) The third horizontal axis (3), the fourth horizontal axis (24), the fifth horizontal axis (25), and the handrail (28) are arranged from bottom to top to form a vertical or slightly inclined plane. The lower end of the handrail (28) is fixed on the fifth horizontal axis (25). The two ends of the fifth horizontal axis (25) are fixedly connected to the upper ends of the two third connecting plates (27) respectively. The lower ends of the two third connecting plates (27) are fixedly connected to the two ends of the fourth horizontal axis (24) respectively. Two second traveling wheels (26) are connected to the fourth horizontal axis (24) through bearings. The two second traveling wheels (26) are symmetrically arranged about the vertical center line of the fourth horizontal axis (24). The bottom surface of the two second traveling wheels (26) is in contact with the seabed surface and is at the same height as the bottom surface of the first traveling wheel (5).
[0042] When manual labor is used, the work steps are as follows:
[0043] The first step is to place the seedling tray (20) on the seedling tray support (23), arrange the seedling ropes in the seedling tray, arrange the transplanting units vertically and orderly, and loosen the bottom of the transplanting units so that the seedling ropes can be easily dragged away from the seedling tray in subsequent operations.
[0044] The second step is to open the initial rope end of the seedling rope and manually drag the rope end down the inclined surface of the first guide plate (7). The rope end drags the transplanting unit on the subsequent seedling rope through the upper surface of the first guide plate (7), the lower part of the first guide roller (6), the first guide groove and the second guide groove in sequence. The posture of the transplanting unit also changes from vertical in the seedling tray to lying flat on the surface of the first guide plate (7). Then, under the action of the first guide groove, it slowly stands up from lying flat until it becomes completely upright under the action of the second guide groove. Finally, it falls into the seedling rope transplanting channel with the bottom plate open. Use bamboo forks or bamboo nails to fix the aforementioned rope end to the bottom seabed in the space of the seedling rope transplanting channel, and gently press down the second guide plate (8) so that the plow assembly (14) and the soil covering structure (15) are inserted into the seabed.
[0045] The third step involves manually holding the upper end of the handrail (28) and dragging the human-assisted walking mechanism forward in a backward posture. Since the seedling tray support (23) on the human-assisted walking mechanism is fixedly connected to the second horizontal axis (2) of the aforementioned seaweed seedling rope transplanting device, the seaweed seedling rope transplanting device is dragged forward. During the forward movement of the seedling rope transplanting device, the plow blade assembly (14) welded to the bottom surface of the second guide plate (8) creates a C-shaped groove. Because the seedling rope end has been fixed to the seabed, the subsequent transplanting unit is placed in the transplanting device... As the plant moves forward, it passes through the perforated bottom plate and falls into the C-shaped trench. The soil covering structure (15) after the plow assembly (14) gathers the mud and sand on both sides of the C-shaped trench towards the center, fills the trench and covers the roots of the transplanting unit. At the same time, the compaction wheel (16) compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the net space of the reserved transplanting channel. Thus, the transplanting units on the seedling rope are transplanted into the seabed in sequence. The transplanting depth is the trenching depth of the plow assembly (14), which is 3-5cm.
[0046] According to the diagram Figure 7-8 When using a hull or raft for towing operations, two additional towing links (33) are added. A third short shaft (29) is fixedly suspended from the outer edge of both sides of the hull or raft. The other end of the third short shaft (29) is fixedly connected to one end of two fourth connecting plates (30). A sixth horizontal shaft (31) is set, with both ends fixedly connected to the other ends of two fourth connecting plates (30). A rotatable second guide roller (32) is set on the sixth horizontal shaft (31). The lengths of the two towing links (33) are... The seaweed transplanting device is arranged symmetrically about the center line of the transplanting direction in the degree direction. One end of each of the two towing links (33) is hinged to the two ends of the sixth horizontal axis, and the other end is hinged to the second horizontal axis (2) of the seaweed transplanting device. When the depth of the hull or the raft from the seabed surface decreases or increases, it drives the angle between the two towing links (33) and the horizontal plane to decrease or increase, and drags the seaweed transplanting device to a greater or lesser distance from the hull or the raft, so as to adapt to the changing operational needs of the sea level and water depth.
[0047] When using a vessel or floating raft for towing operations, the operational steps are as follows:
[0048] The first step is to place the seedling tray (20) on the hull or the deck of the raft, arrange the seedling ropes in the seedling tray, arrange the transplanting units vertically and orderly, and loosen the bottom of the transplanting units so that the seedling ropes can be easily dragged away from the seedling tray in subsequent operations.
[0049] The second step is to open the initial rope end of the seedling rope and manually drag the rope end down along the inclined surface of the dragging link (33) and the first guide plate (7). The rope end drags the transplanting unit on the subsequent seedling rope through the upper surface of the second guide roller (32), the space between the dragging link (33), the upper surface of the first guide plate (7), the lower part of the first guide roller (6), the first guide groove and the second guide groove. The posture of the transplanting unit also changes from vertical in the seedling tray to lying flat on the surface of the first guide plate (7). Then, under the action of the first guide groove, it slowly stands up from lying flat until it becomes completely upright under the action of the second guide groove. Finally, it falls into the seedling rope transplanting channel with the bottom plate open. Use bamboo forks or bamboo nails to fix the aforementioned rope end to the bottom seabed in the seedling rope transplanting channel space, and gently press down the second guide plate (8) so that the plow assembly (14) and the soil covering structure (15) are inserted into the seabed.
[0050] The third step involves starting the hull or raft forward and dragging the connecting rod (33) forward. Since the dragging connecting rod (33) is hinged to the second horizontal axis (2) of the aforementioned seaweed seedling rope transplanting device, it drags the seaweed seedling rope transplanting device forward. Because the weight of the seaweed seedling rope transplanting device exceeds its buoyancy, the first traveling wheel (5) of the transplanting device will always travel close to the seabed surface. During the forward movement of the seedling rope transplanting device, the plow blade assembly (14) welded to the bottom surface of the second guide plate (8) creates a C-shaped groove. Since the seedling rope end has been fixed to the seabed, subsequent... As the transplanting device moves forward, the transplanting units pass through the perforated bottom plate and fall into the C-shaped trench. The soil covering structure (15) after the plow assembly (14) gathers the mud and sand on both sides of the C-shaped trench towards the center, filling the trench and covering the roots of the transplanting units. At the same time, the compaction wheel (16) compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the net space of the pre-reserved transplanting channel. Thus, the transplanting units on the seedling rope are transplanted into the seabed in sequence. The transplanting depth is the trenching depth of the plow assembly (14), which is 3-5 cm.
[0051] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

6. A method for transplanting seaweed seedlings using the seaweed seedling rope transplanting device according to any one of claims 1-5, characterized in that, The operation can be carried out manually or by towing using a vessel or raft, as detailed below: When manual operation is used, a human-assisted walking structure is added. The human-assisted walking structure includes a seedling tray support (23), a fourth horizontal axis (24), a fifth horizontal axis (25), two second walking wheels (26), two third connecting plates (27), and a manual handrail (28). The seedling tray support (23) is a grid-shaped fixed frame structure. Its upper edge is fixed on the fifth horizontal axis (25), and its lower edge is fixed on the second horizontal axis (2). It is arranged at an inclination. The inclination direction and angle are the same as the first guide base plate (7). Its width is also the same as the opening at the upper end of the first guide base plate (7). Its length depends on the length of the seedling tray placed on it. The horizontal direction of the fourth horizontal axis (24) and the fifth horizontal axis (25) is parallel to the first horizontal axis (1), the second horizontal axis (2), and the third horizontal axis (3). The fourth horizontal axis (24), the fifth horizontal axis (25), and the manual handrail (28) are arranged sequentially from bottom to top. A vertical or slightly inclined plane is formed. The lower end of the handrail (28) is fixed on the fifth horizontal axis (25). The two ends of the fifth horizontal axis (25) are fixedly connected to the upper ends of the two third connecting plates (27) respectively. The lower ends of the two third connecting plates (27) are fixedly connected to the two ends of the fourth horizontal axis (24) respectively. Two second traveling wheels (26) are connected to the fourth horizontal axis (24) through bearings. The two second traveling wheels (26) are symmetrically arranged about the vertical center line of the fourth horizontal axis (24). The bottom surfaces of the two second traveling wheels (26) are in contact with the seabed surface and are at the same height as the bottom surface of the first traveling wheel (5). When manual labor is used, the work steps are as follows: The first step is to place the seedling tray (20) on the seedling tray support (23), arrange the seedling ropes in the seedling tray, arrange the transplanting units vertically and orderly, and loosen the bottom of the transplanting units so that the seedling ropes can be easily dragged away from the seedling tray in subsequent operations. The second step is to open the initial rope end of the seedling rope and manually drag the rope end down the inclined surface of the first guide plate (7). The rope end drags the transplanting unit on the subsequent seedling rope through the upper surface of the first guide plate (7), the lower part of the first guide roller (6), the first guide groove and the second guide groove in sequence. The posture of the transplanting unit also changes from upright in the seedling tray to lying flat on the surface of the first guide plate (7). Then, under the action of the first guide groove, it slowly stands up from lying flat until it becomes completely upright under the action of the second guide groove. Finally, it falls into the seedling rope transplanting channel with the hole in the bottom plate. Use bamboo forks or bamboo nails to fix the aforementioned rope end to the bottom seabed in the space of the seedling rope transplanting channel, and gently press down the second guide plate (8) so that the plow assembly (14) and the soil covering structure (15) are inserted into the seabed. In the third step, a person holds the upper end of the manual handrail (28) and drags the manual auxiliary walking mechanism forward in a backward posture. Because the seedling tray bracket (23) on the manual auxiliary walking mechanism is fixedly connected to the second horizontal axis (2) of the aforementioned seaweed seedling rope transplanting device, the seaweed seedling rope transplanting device is dragged forward. During the forward movement of the seedling rope transplanting device, the plow blade assembly (14) welded to the bottom surface of the second guide plate (8) opens a C-shaped groove. Since the seedling rope end has been fixed to the seabed, the subsequent transplanting unit will transplant the seedlings. As the device moves forward, it passes through the perforated bottom plate and falls into the C-shaped trench. The soil covering structure (15) after the plow assembly (14) gathers the mud and sand on both sides of the C-shaped trench towards the center, fills the trench and covers the roots of the transplanting unit. At the same time, the compaction wheel (16) compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the reserved transplanting channel. Thus, the transplanting units on the seedling rope are transplanted into the seabed in sequence. The transplanting depth is the trenching depth of the plow assembly (14), which is 3-5cm. When using a hull or raft for towing operations, two additional towing links (33) are added. A third short shaft (29) is fixedly suspended from the outer edge of both sides of the hull or raft. The other end of the third short shaft (29) is fixedly connected to one end of each of the two fourth connecting plates (30). A sixth horizontal shaft (31) is set, with both ends fixedly connected to the other ends of each of the two fourth connecting plates (30). A second guide roller (32) capable of rotation is set on the sixth horizontal shaft (31). The length of the two towing links (33) is... The direction of the seaweed transplanting device is arranged symmetrically and parallel to the center line of the transplanting direction. One end of each of the two towing links (33) is hinged to the two ends of the sixth horizontal axis, and the other end is hinged to the second horizontal axis (2) of the seaweed transplanting device. When the depth of the hull or the raft from the seabed surface decreases or increases, it causes the angle between the two towing links (33) and the horizontal plane to decrease or increase, and drags the seaweed transplanting device to a greater or lesser distance from the hull or the raft, thereby adapting to the changing operational needs of the sea level and water depth. When using a vessel or floating raft for towing operations, the operational steps are as follows: The first step is to place the seedling tray (20) on the hull or the deck of the raft, arrange the seedling ropes in the seedling tray, make the transplanting units stand upright and orderly, and loosen the bottom of the transplanting units so that the seedling ropes can be easily dragged away from the seedling tray in subsequent operations. The second step is to open the initial rope end of the seedling rope and manually drag the rope end down along the inclined surface of the dragging link (33) and the first guide bottom plate (7). The rope end drags the transplanting unit on the subsequent seedling rope through the upper surface of the second guide roller (32), the space between the dragging link (33), the upper surface of the first guide bottom plate (7), the bottom of the first guide roller (6), the first guide groove and the second guide groove. The posture of the transplanting unit also changes from vertical in the seedling tray to lying flat on the surface of the first guide bottom plate (7). Then, under the action of the first guide groove, it slowly stands up from lying flat until it becomes completely upright under the action of the second guide groove. Finally, it falls into the seedling rope transplanting channel with the hole in the bottom plate. Use bamboo forks or bamboo nails to fix the aforementioned rope end to the bottom seabed in the space of the seedling rope transplanting channel, and gently press down the second guide bottom plate (8) so that the plow assembly (14) and the soil covering structure (15) are inserted into the seabed. The third step involves starting the hull or raft forward and dragging the connecting rod (33) forward. Because the dragging connecting rod (33) is hinged to the second horizontal axis (2) of the aforementioned seaweed seedling rope transplanting device, the seaweed seedling rope transplanting device is dragged forward. Since the self-weight of the seaweed seedling rope transplanting device exceeds its buoyancy, the first traveling wheel (5) of the transplanting device will always travel close to the seabed surface. During the forward movement of the seedling rope transplanting device, the plow blade assembly (14) welded to the bottom surface of the second guide plate (8) opens a C-shaped groove. Since the seedling rope end has been fixed to the seabed, the subsequent... As the transplanting device moves forward, the transplanting units pass through the perforated bottom plate and fall into the C-shaped trench. The soil covering structure (15) after the plow assembly (14) gathers the mud and sand on both sides of the C-shaped trench towards the center, fills the trench and covers the roots of the transplanting units. At the same time, the compaction wheel (16) compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the space of the reserved seedling rope transplanting channel. Thus, the transplanting units on the seedling rope are transplanted into the seabed in sequence. The transplanting depth is the trenching depth of the plow assembly (14), which is 3-5 cm.
