Description

Technical Field

[0001] The utility model belongs to the technical field of marine ecological restoration, and more specifically relates to a transplanting device suitable for seagrass bed ecological restoration. Background Art

[0002] Transplantation, seeding, and habitat restoration are the primary methods for protecting and restoring seagrass beds, with transplantation being the most common. Transplantation involves organizing artificial seedlings or seagrass rhizomes collected from existing seabeds into seagrass seedling transplant units. These units are then manually or mechanically planted in the restoration area, hoping to achieve large-scale restoration of seagrass beds through the propagation of the seagrass' own tissues. Currently, transplantation technology faces two major challenges. First, the transplanted bundles are difficult to secure on the seabed and are easily lost due to waves, a factor that contributes significantly to the low success rate of seagrass transplants. Second, there is a lack of automated equipment, with most operations relying on manual planting of seedlings one by one. This approach is subject to numerous restrictions, low efficiency, and high costs, making large-scale seagrass bed protection and restoration impossible. Utility Model Content

[0010] Preferably, when using the seaweed seedling rope transplanting device to transplant seaweed seedling ropes at sea, both manual labor and towing operations such as a ship or a floating raft can be used, as follows:

[0012] When manual labor is used, preferably, the operation 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 so that the transplanting units are arranged vertically and orderly, and loosen the bottom of the transplanting unit 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, manually drag the rope end downward along the inclined surface of the first guide plate (7), and the rope end drags the transplanting unit on the subsequent seedling rope through the upper surface of the first guide plate (7), the bottom 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 being upright in the seedling tray to lying flat on the surface of the first guide plate (7), and then slowly standing up from lying flat under the action of the first guide groove until it becomes a completely upright posture under the action of the second guide groove, and finally falls into the seedling rope transplanting channel with a hole in the bottom plate. A bamboo fork or bamboo nail is used to fix the rope end on the bottom seabed in the seedling rope transplanting channel space, and the second guide plate (8) is gently pressed downward to allow the plow blade assembly (14) and the covering structure (15) to be inserted into the seabed;

[0015] In the third step, a person holds the upper end of the manual handrail (28) and drags the human-assisted walking mechanism forward in a backward posture. Since the seedling tray bracket (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 process of the seedling rope transplanting device moving forward, the plow blade assembly (14) welded on the bottom surface of the second guide bottom plate (8) opens a C-shaped groove. Since the rope head of the seedling rope has been fixed on the seabed, the subsequent transplanting unit is in the transplanting device. As the unit moves forward, it also passes through the hollow bottom plate in turn and falls into the C-shaped groove. The covering structure (15) behind the plow assembly (14) gathers the mud and sand on both sides of the C-shaped groove toward the center, fills the groove and covers the roots of the transplanting units. At the same time, the compacting wheel (16) behind it compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the clear space of the aforementioned reserved transplanting channel. As a result, the transplanting units on the seedling rope are transplanted into the seabed in turn. The transplanting depth is the trenching depth of the plow assembly (14), that is, 3-5 cm.

[0016] When a hull or a floating raft is used for towing operations, preferably, two towing connecting rods (33) are added, and a third short shaft (29) is fixedly suspended on the outer edges of both sides of the hull or the floating raft. The other ends of the third short shaft (29) are fixedly connected to one end of the two fourth connecting plates (30). A sixth transverse shaft (31) is provided, and its two ends are fixedly connected to the other ends of the two fourth connecting plates (30). A second guide roller (32) that can rotate is provided on the sixth transverse shaft (31). The two towing connecting rods (33) are fixedly connected to the second guide roller (32). The length direction is parallel and symmetrically arranged about the center line of the seaweed transplanting device in the transplanting direction, one end of the two dragging connecting rods (33) is hinged to the two ends of the sixth horizontal axis respectively, 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 floating raft from the seabed surface decreases or increases, the angle between the two dragging connecting rods (33) and the horizontal plane becomes smaller or larger, and the seaweed transplanting device is dragged farther or closer to the hull or the floating raft, thereby adapting to the operation requirements of the constantly changing sea level and water depth;

[0017] When using a hull or a floating raft for towing operations, preferably, the operation steps are as follows:

[0018] The first step is to place the seedling tray (20) on the hull or raft deck, arrange the seedling ropes in the seedling tray, make the transplanting units upright and orderly arranged, and loosen the bottom of the transplanting unit so that the seedling ropes can be easily dragged away from the seedling tray during subsequent operations;

[0019] The second step is to open the initial rope head of the seedling rope, manually drag the rope head downward along the inclined surface of the dragging connecting rod (33) and the first guide plate (7), and the rope head drags the transplanting unit on the subsequent seedling rope through the upper surface of the second guide roller (32), the space between the dragging connecting rod (33), the upper surface of the first guide plate (7), the bottom 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 the vertical position in the seedling tray to the flat position on the surface of the first guide plate (7), and then slowly stands up from the flat position under the action of the first guide groove until it becomes a completely upright posture under the action of the second guide groove, and finally falls into the seedling rope transplanting channel with a hole in the bottom plate. The rope head is fixed to the bottom seabed in the space of the seedling rope transplanting channel with a bamboo fork or bamboo nail, and the second guide plate (8) is gently pressed downward to allow the plow blade assembly (14) and the covering structure (15) to be inserted into the seabed;

[0020] The third step is to start the hull or raft to move forward, and drag the connecting rod (33) forward. Since the dragging connecting rod (33) is hinged with the second transverse axis (2) of the aforementioned seaweed seedling rope transplanting device, the seaweed seedling rope transplanting device is dragged forward. Since the dead weight of the seaweed seedling rope transplanting device exceeds its buoyancy, the first walking wheel (5) of the transplanting device will always walk close to the surface of the seabed. During the process of the seedling rope transplanting device moving forward, the plow blade assembly (14) welded on the bottom surface of the second guide bottom plate (8) opens a C-shaped groove. Since the rope end of the seedling rope has been fixed on the seabed, the subsequent As the transplanting device moves forward, the transplanting units also pass through the hollow bottom plate in turn and fall into the C-shaped groove. The covering structure (15) behind the plow assembly (14) gathers the mud and sand on both sides of the C-shaped groove toward the center, fills the groove and covers the roots of the transplanting units. At the same time, the compacting wheel (16) behind it compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the aforementioned reserved clear space for transplanting the rice seedlings. As a result, the transplanting units on the seedling rope are transplanted into the seabed in turn. The transplanting depth is the trenching depth of the plow assembly (14), that is, 3-5 cm.

[0021] The beneficial effects of adopting the above technical solution are:

[0022] 1. Use ropes as carriers for seaweed seedlings or mature transplant bundles to prevent the loss of seaweed seedlings caused by waves and facilitate mechanized auxiliary operations or large-scale automatic operations;

[0023] 2. A seaweed seedling rope transplanting device with a simple structure, low cost, and easy operation. It greatly reduces labor intensity while ensuring operational standardization and improving transplant success rate.

[0024] 3. A seaweed seedling rope transplanting device can be used for both manual assisted operations and large-scale automated operations using a hull or raft. The latter can adapt to the operation requirements of different water depths, has high operating efficiency, and is highly adaptable to offshore working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] According to the instructions Figure 5-6When manpower is used for operation, a manpower-assisted walking structure is added, and the manpower-assisted walking structure includes a seedling tray bracket (23), a fourth transverse axis (24), a fifth transverse axis (25), two second walking wheels (26), two third connecting plates (27), and an artificial handrail (28); the seedling tray bracket (23) is a lattice fixed frame structure, the upper edge is fixed on the fifth transverse axis (25), and the lower edge is fixed on the second transverse axis (2), and is arranged obliquely, with the inclination direction and angle being the same as the first guide bottom plate (7), the width is also the same as the width of the opening at the upper end of the first guide bottom plate (7), and the length depends on the length of the seedling tray placed thereon; the horizontal directions of the fourth transverse axis (24) and the fifth transverse axis (25) are parallel to the first transverse axis (1), the second transverse axis ( 2) and the third transverse axis (3), the fourth transverse axis (24), the fifth transverse axis (25), and the artificial handrail (28) are arranged in sequence from bottom to top to form a vertical or slightly inclined plane, the lower end of the artificial handrail (28) is fixed on the fifth transverse axis (25), the two ends of the fifth transverse axis (25) are respectively fixedly connected to the upper ends of the two third connecting plates (27), the lower ends of the two third connecting plates (27) are respectively fixedly connected to the two ends of the fourth transverse axis (24), the fourth transverse axis (24) is connected to two second running wheels (26) through bearings, the two second running wheels (26) are symmetrically arranged about the vertical center line of the fourth transverse axis (24), the bottom surfaces of the two second running wheels (26) are in contact with the seabed surface and are at the same height as the bottom surface of the first running wheel (5);

[0042] When manual labor is used, the 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 so that the transplanting units are arranged vertically and orderly, and loosen the bottom of the transplanting unit 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 head of the seedling rope, manually drag the rope head downward along the inclined surface of the first guide plate (7), and drag the transplanting unit on the subsequent seedling rope through the upper surface of the first guide plate (7), the bottom 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), and then slowly stands up from lying flat under the action of the first guide groove until it becomes a completely upright posture under the action of the second guide groove, and finally falls into the seedling rope transplanting channel with a hole in the bottom plate. Use bamboo forks or bamboo nails to fix the rope head on the bottom seabed in the space of the seedling rope transplanting channel, and gently press the second guide plate (8) downward to allow the plow blade assembly (14) and the covering structure (15) to be inserted into the seabed;

[0045] In the third step, a person holds the upper end of the manual handrail (28) and drags the human-assisted walking mechanism forward in a backward posture. Since the seedling tray bracket (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 process of the seedling rope transplanting device moving forward, the plow blade assembly (14) welded on the bottom surface of the second guide bottom plate (8) opens a C-shaped groove. Since the rope head of the seedling rope has been fixed on the seabed, the subsequent transplanting unit is in the transplanting device. During the process of moving forward, the transplanting units also pass through the hollow bottom plate in turn and fall into the C-shaped groove. The covering structure (15) behind the plow assembly (14) gathers the mud and sand on both sides of the C-shaped groove toward the center, fills the groove and covers the roots of the transplanting units. At the same time, the compacting wheel (16) compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the clear space of the aforementioned reserved transplanting channel. Thus, the transplanting units on the seedling rope are transplanted into the seabed in turn. The transplanting depth is the furrowing depth of the plow assembly (14), that is, 3-5 cm.

[0046] According to the instructions Figure 7-8 When a hull or a floating raft is used for towing operations, two towing connecting rods (33) are added, and a third short shaft (29) is fixedly suspended on the outer edges of both sides of the hull or the floating raft. The other ends of the third short shaft (29) are fixedly connected to one end of the two fourth connecting plates (30). A sixth transverse shaft (31) is provided, and its two ends are fixedly connected to the other ends of the two fourth connecting plates (30). A second guide roller (32) that can rotate is provided on the sixth transverse shaft (31). The lengths of the two towing connecting rods (33) are fixedly connected to the other ends of the two fourth connecting plates (30). The two dragging links (33) are arranged parallel and symmetrically about the center line of the seaweed transplanting device in the transplanting direction, one end of each of the two dragging 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 floating raft from the seabed surface decreases or increases, the angle between the two dragging links (33) and the horizontal plane decreases or increases, and the seaweed transplanting device is dragged farther or closer to the hull or the floating raft, thereby adapting to the operation requirements of the constantly changing sea level and water depth;

[0047] When using a hull or raft to tow the vehicle, the following steps are taken:

[0048] The first step is to place the seedling tray (20) on the hull or raft deck, arrange the seedling ropes in the seedling tray so that the transplant units are arranged vertically and orderly, and loosen the bottom of the transplant unit so that the seedling ropes can be easily dragged away from the seedling tray during subsequent operations;

[0049] The second step is to open the initial rope head of the seedling rope, manually drag the rope head downward along the inclined surface of the dragging connecting rod (33) and the first guide plate (7), and the rope head drags the transplanting unit on the subsequent seedling rope through the upper surface of the second guide roller (32), the space between the dragging connecting rod (33), the upper surface of the first guide plate (7), the bottom 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 the vertical position in the seedling tray to the flat position on the surface of the first guide plate (7), and then slowly stands up from the flat position under the action of the first guide groove until it becomes a completely upright posture under the action of the second guide groove, and finally falls into the seedling rope transplanting channel with a hole in the bottom plate. The rope head is fixed to the bottom seabed in the space of the seedling rope transplanting channel with a bamboo fork or bamboo nail, and the second guide plate (8) is gently pressed downward to allow the plow blade assembly (14) and the covering structure (15) to be inserted into the seabed;

[0050] The third step is to start the hull or raft to move forward, and drag the connecting rod (33) forward. Since the dragging connecting rod (33) is hinged with the second transverse axis (2) of the aforementioned seaweed seedling rope transplanting device, the seaweed seedling rope transplanting device is dragged forward. Since the dead weight of the seaweed seedling rope transplanting device exceeds its buoyancy, the first walking wheel (5) of the transplanting device will always walk close to the surface of the seabed. During the process of the seedling rope transplanting device moving forward, the plow blade assembly (14) welded on the bottom surface of the second guide bottom plate (8) opens a C-shaped groove. Since the rope end of the seedling rope has been fixed on the seabed, the subsequent As the transplanting device moves forward, the transplanting units also pass through the hollow bottom plate in turn and fall into the C-shaped groove. The covering structure (15) behind the plow assembly (14) gathers the mud and sand on both sides of the C-shaped groove toward the center, fills the groove and covers the roots of the transplanting units. At the same time, the compacting wheel (16) behind it compacts the mud and sand that has just been buried. The upper part of the transplanting unit also passes through the aforementioned reserved clear space for transplanting the rice seedlings. As a result, the transplanting units on the seedling rope are transplanted into the seabed in turn. The transplanting depth is the trenching depth of the plow assembly (14), that is, 3-5 cm.

[0051] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and utility model concept of the present invention, should be covered by the protection scope of the present invention.
