Description

Technical Field

[0001] This utility model relates to the field of marine ecological restoration technology, and in particular to a hand-push sowing device for seaweed seeds. Background Technology

[0002] Seagrass is the only type of higher angiosperm on Earth that can live entirely in seawater. When seagrass grows in large, continuous areas, it is called a seagrass bed. Seagrass beds possess extremely high productivity and a complex food chain structure, making them an important nearshore marine ecosystem that plays a crucial role in improving and regulating the ecological environment. However, seagrass beds are easily damaged by human activities. Since 1990, global seagrass beds have been decreasing at a rate of 7% per year. The ecological problems of seagrass beds are becoming increasingly serious, and their protection and restoration have become the most urgent need for ecological restoration today.

[0003] Seed propagation, plant transplantation, and habitat restoration are the main methods for seagrass bed restoration. Among these, habitat restoration has a long restoration cycle, while seed propagation and transplantation can improve the genetic diversity of the restored seagrass beds and are less destructive, making them methods worthy of strong promotion. However, currently, seed propagation and transplantation methods mostly rely on manual labor, which can only be carried out at low tide, resulting in low efficiency and high costs. With rising labor costs, seagrass seed sowing is receiving increasing attention.

[0004] Seagrass seed rope sowing technology involves wrapping seagrass seeds in rope-like structures made of hydrolyzed materials to form seed ropes, facilitating sowing. This is a new technology for seagrass bed restoration. Existing seed rope sowing devices typically use fixed-angle push-pull rods. However, different operators often have different usage habits and force application angles. Therefore, improving the adaptability of the push-pull rods, facilitating operation, reducing the labor intensity (fatigue) of different users, and thus improving work efficiency are problems that urgently need to be solved by those skilled in the art.

[0009] A hand-push seaweed seed sowing device, comprising:

[0010] The structural frame is provided with pairs of rollers at both its front and rear ends;

[0011] A push rod support box is symmetrically arranged on both sides of the structural frame. The push rod support box is provided with a through groove composed of multiple U-shaped grooves of different angles connected continuously, and the adjacent U-shaped grooves form an included angle.

[0012] The push rod has an inverted U-shaped structure. The lower end of the push rod has an outwardly bent part. The bent part is inserted into the through groove and can slide along the through groove into the U-shaped groove at different angles to adjust the tilt angle of the push rod relative to the structural frame.

[0013] A connecting rod connects the structural frame and the push rod;

[0014] After the bent portion slides into any of the U-shaped grooves, the push rod, the connecting rod, and the structural frame form a triangular support structure, so that when the push rod is pushed, the push rod and the structural frame remain relatively fixed.

[0015] The through groove also includes a sliding groove, which is connected to the top of the U-shaped groove in a horizontal direction. After the bent part is pulled out of the U-shaped groove, it enters the sliding groove to serve as a guide channel before the bent part is selected to insert into any U-shaped groove.

[0016] It also includes a winding device for winding seaweed seed rope;

[0017] The winding device includes a winding reel and a reel bracket. The reel bracket is fixedly connected to the upper part of the push rod. The reel bracket has a winding shaft, and the winding reel is rotatably connected to the reel bracket through the winding shaft.

[0018] It also includes conduit;

[0019] The conduit is a hollow tubular structure, fixed to the bottom of the structural frame, and located between two pairs of front and rear rollers;

[0020] The front side of the push rod is provided with multiple wire loops. After the seaweed seed rope is led out from the winding reel, it is sequentially threaded through the wire loops and the threading tube.

[0021] The lower end of the threading tube is bent at 90° so that the seaweed seed rope is horizontally led out of the threading tube and introduced into the seabed.

[0022] It also includes plowshares;

[0023] The vertical cross-section of the plow blade is L-shaped. The plow blade is fixed to the bottom of the structural frame and is located in front of the conduit.

[0024] The bottom edge of the conduit is higher than the plow blade.

[0025] It also includes soil covering boards;

[0026] The soil covering board has an upright rectangular structure, and the soil covering board is fixed to the bottom of the structural frame and located behind the conduit.

[0027] The bottom edge of the soil covering plate is flush with the plane of the lowest point of the roller.

[0028] The structural frame includes a horizontally arranged structural plate and side plates fixed to both sides of the structural plate;

[0029] The front and rear ends of the side plate are respectively provided with bearing seats, and the left and right opposite bearing seats are provided with a wheel axle;

[0030] The roller is mounted on the axle;

[0031] The push rod support box is fixedly mounted on the side plate;

[0032] The diameter of the push rod is matched with the width of the U-shaped groove;

[0033] The upper part of the push rod has a rearward-curving grip section.

[0034] (III) Beneficial Effects

[0035] The beneficial effects of this utility model are as follows: The seagrass seed hand-push sowing device provided by this utility model is a sowing device for sowing seagrass seed ropes. By setting up a push rod support box and connecting rod, the tilt angle of the push rod can be quickly adjusted in multiple stages, allowing operators of different heights to push the device in a comfortable and labor-saving posture, greatly improving the user experience and ease of operation, reducing labor intensity, and increasing work efficiency. The device has a simple structure and is easy to move and operate in complex environments such as tidal flats and shallow water, providing an effective and specialized tool for sowing seagrass seeds in seagrass beds.

[0036] By setting a connecting rod, the angle of the push rod is kept stable and reliable during the sowing process, preventing accidental slippage and ensuring operational stability and sowing quality.

[0037] By incorporating a winding device (winding reel and reel support), the orderly storage and automatic feeding of seaweed seed ropes are achieved. This avoids problems such as rope tangling, knotting, or uneven feeding caused by manual reel handling, ensuring the continuity and stability of the sowing process and improving sowing efficiency.

[0038] By using a 90° bend in the threading tube, the seaweed seed rope, which was guided vertically, is transformed into a horizontally directed rope, thus precisely placing the seed rope on the seabed surface at a predetermined depth instead of scattering it randomly, thereby improving the accuracy and consistency of seeding.

[0039] By setting multiple guide rings to form a guiding path from the winding reel to the threading tube, the movement range of the seaweed seed rope is effectively constrained, preventing it from swinging randomly in front of the push rod. This further avoids tangling and friction wear, ensuring that the seed rope can be smoothly and with low resistance delivered to the threading tube.

[0040] By setting up an L-shaped plow blade, a regular trench can be effectively dug in the seabed mud, ensuring that trenching is carried out before sowing, so that the seaweed seed rope can fall accurately into the bottom of the trench, creating conditions for subsequent covering and compaction, which is conducive to seed germination and planting.

[0041] A soil-covering plate is used to push the loose soil turned up by the plow into the furrow, covering the seaweed seed ropes. The design of the soil-covering plate's bottom edge being flush with the lowest point of the roller ensures that the plate effectively levels the soil without inserting itself too deeply into the mud and causing excessive resistance. Working in conjunction with the rear roller, it compacts the soil, completing the entire process of furrowing, sowing, covering, and compacting. This simulates an optimal sowing environment and improves seed survival rates. Attached Figure Description

[0063] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] The seaweed seed rope 10 is made by wrapping seaweed seeds in a rope-like material that has been hydrolyzed. The hand-push seaweed seed sowing device provided by this invention is applied to the seaweed seed rope 10. By setting up a push rod support box 5 and a connecting rod 6, the angle of the push rod 7 can be adjusted, allowing operators of different heights to push the device comfortably and effortlessly, greatly improving user experience and ease of operation, and reducing labor intensity. This device has a simple structure and is easy to move and operate in complex environments such as tidal flats and shallow water, providing an effective and specialized tool for seabed sowing.

[0065] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0066] See appendix Figure 1-4 As shown, this embodiment of the invention provides a hand-push seaweed seed sowing device, including a structural frame 1, a push rod support box 5, a push rod 7, and a connecting rod 6. The push rod support box 5 is symmetrically arranged on both sides of the structural frame 1. The push rod support box 5 has a through groove formed by continuously connecting multiple U-shaped grooves 15 at different angles, with adjacent U-shaped grooves 15 forming an included angle. The push rod 7 has an inverted U-shaped structure, and the lower end of the push rod 7 has an outwardly bent part. The bent part is inserted into the through groove and can slide along the through groove into U-shaped grooves 15 at different angles to adjust the tilt angle of the push rod 7 relative to the structural frame 1. Through the cooperation of the push rod support box 5 and the push rod 7, the bent part at the lower end of the push rod 7 slides and is fixed in the U-shaped grooves 15 at different angles, realizing multi-level and rapid adjustment of the tilt angle of the push rod 7. This allows operators of different heights to push the device in a comfortable and effortless posture, greatly improving the user experience and ease of operation, and reducing labor intensity.

[0067] The through groove also includes a sliding groove 16, which is connected horizontally to the top of the U-shaped groove 15. This sliding groove 16 serves as a guide channel before the bent portion is inserted into any of the U-shaped grooves 15. The bent portion of the push rod 7 is inserted into the sliding groove 16 and slides horizontally along the sliding groove 16 to a U-shaped groove 15 at a preset angle, where it is then inserted. The included angle between adjacent U-shaped grooves 15 is typically 20-30°, but can be selected according to actual needs. By setting multiple U-shaped grooves 15 with different angles, more options are provided for the use of the push rod 7.

[0068] The diameter of the push rod 7 matches the width of the U-shaped groove 15, ensuring that the push rod slides smoothly in the groove without significant wobbling, providing a good adjustment feel and accurate positioning after fixing.

[0069] The upper part of the push rod 7 has a backward-curving grip section, which forms an ergonomic push rod handle, making it more comfortable and effortless for the operator to push, and further optimizing the user experience.

[0070] The connecting rod 6 connects the structural frame 1 and the push rod 7. It is used to lock the relative position of the push rod 7 and the structural frame 1 after the bent part slides to any U-shaped groove 15. This ensures that the angle of the push rod 7 is stable and reliable during the sowing process, and will not slide accidentally, thus ensuring the stability of the operation and the sowing quality.

[0071] After the push rod 7 slides into any U-shaped groove 15 at the bend, the push rod 7, connecting rod 6, and structural frame 1 form a triangular support structure, so that the push rod 7 and structural frame 1 remain relatively fixed when the push rod 7 is pushed. After the push rod 7 is pulled out of the U-shaped groove 15 at the bend, it enters the slide groove 16, and the angle of the push rod 7 can be adjusted again.

[0072] The structural frame 1 has pairs of rollers 3 at both its front and rear ends. The structural frame 1 includes a horizontally arranged structural plate and side plates fixed to both sides of the structural plate. Bearing seats 2 are located at the front and rear ends of the side plates, and an axle 4 is positioned between the opposing bearing seats 2. The rollers 3 are mounted on the axle 4. This connection between the bearing seats 2 and the axle 4 ensures smooth rotation of the rollers 3 and structural robustness, making movement of the device on soft seabed easier and improving its load-bearing capacity. The modular design also facilitates manufacturing, assembly, and maintenance.

[0073] It also includes a winding device for winding the seaweed seed rope 10. The winding device includes a winding reel 11 and a reel support 12. The reel support 12 is fixedly connected to the upper part of the push rod 7 and has a winding shaft. The winding reel 11 is rotatably connected to the reel support 12 via the winding shaft. By setting up a dedicated winding device (winding reel 11 and reel support 12), the orderly storage and automatic feeding of the seaweed seed rope 10 are achieved. This avoids the problems of rope tangling, knotting, or uneven feeding caused by manual reel handling, ensuring the continuity and stability of the sowing process and improving sowing efficiency.

[0074] It also includes a threading tube 9, which is a hollow tubular structure fixed to the bottom of the structural frame 1 and located between the front and rear pairs of rollers 3. The lower end of the threading tube 9 has a 90° bend to allow the seaweed seed rope 10 to be led out horizontally. In this embodiment, the outlet of the threading tube 9 is 20mm downward from the plane where the bottom of the roller 3 is located. The threading tube 9 is fixed to the bottom of the structural frame and plays a key guiding and positioning role. Its 90° bend at the lower end can change the vertically guided seaweed seed rope 10 to be led out horizontally, thereby accurately placing the seed rope on the seabed surface at a predetermined depth, instead of scattering it randomly, improving the accuracy and consistency of sowing. Its position between the rollers makes its working state more stable. The front side of the push rod 7 is provided with multiple guide rings 8. After the seaweed seed rope 10 is led out from the winding reel 11, it is sequentially threaded through the guide rings 8 and the threading tube 9 and introduced into the seabed. The multiple guide rings 8 form the guiding path from the winding reel 11 to the threading tube 9. They effectively constrain the movement range of the seaweed seed rope, preventing it from swinging arbitrarily in front of push rod 7, further avoiding tangling and friction wear, and ensuring that the seed rope can be smoothly and with low resistance delivered to the threading tube.

[0075] It also includes a plow blade 13, which has an L-shaped structure on its side. The plow blade 13 is fixed to the bottom of the structural frame 1 and located in front of the threading tube 9. The bottom edge of the threading tube 9 is higher than that of the plow blade 13. The plow blade 13 is a key component for achieving row sowing (furrow sowing). Its L-shaped structure can effectively create a regular furrow in the seabed mud. Located in front of the threading tube, it ensures that furrowing is carried out before sowing, allowing the seagrass seed rope 10 to fall accurately into the bottom of the furrow, creating conditions for subsequent soil covering and compaction, which is beneficial to seed germination and establishment. The threading tube 9 is higher than the plow blade 13, avoiding unnecessary wear on the threading tube 9.

[0076] It also includes a covering plate 14, which is rectangular in shape and fixed to the bottom of the structural frame 1, located behind the threading tube 9. The bottom edge of the covering plate 14 is flush with the plane of the lowest point of the roller 3. The covering plate 14 is the last key step in completing the sowing process. Located behind the threading tube 9, it can promptly push back the loose soil turned up by the plow blade 13 when opening the furrow after the seaweed seed rope 10 falls into the furrow, covering the seaweed seed rope 10. The design of the bottom edge of the covering plate 14 being flush with the lowest point of the roller 3 ensures that the covering plate 14 effectively scrapes the soil level without inserting too deeply into the mud and causing excessive resistance. In conjunction with the rear roller 3 (which also plays a compaction role), it completes the entire agronomic process of furrowing, sowing, covering, and compaction, simulating an excellent sowing environment and improving the seed survival rate.

[0077] The push rod support box 5 has mounting holes at both ends for connecting the side plates. The push rod support box 5 can be fixedly connected to the side plates of the structural frame 1 by screws. The installation method is firm and reliable, which is the basis for ensuring the stable operation of the push rod adjustment function.

[0078] The sowing method using a hand-operated seaweed seed sowing device includes the following steps:

[0079] Step 1: Pre-made seaweed seed rope 10: Wrap the seaweed seeds in a rope-like object to make seaweed seed rope 10, and then wind the seaweed seed rope 10 around the winding spool 11.

[0080] Step Two: Sowing Seaweed Seed Rope 10: The operator first guides one end of the seaweed seed rope 10 wound on the winding reel 11 to the seabed surface through the guide ring 8 and the threading tube 9. Using a special tool, the rope end is pressed firmly into the seabed. The bottoms of the four rollers 3 of the sowing device are placed on the seabed surface with the push rod 7 facing upwards. Then, the operator stands behind the sowing device. The operator can adjust the angle of the push rod 7 by moving the tube end of the push rod 7 within the three U-shaped grooves 15 of the push rod support box 5, according to their height, terrain slope, and other actual conditions. Find a better angle of force, then hold the horizontal bar on the push rod 7 and push the device forward. The plow blade 13 opens a groove on the seabed surface, and the seaweed seed rope 10 pressed to the seabed surface falls into the groove. Then the soil covering plate 14 pushes the plow blade to plow out the loose soil and bury the seaweed seed rope 10 in the groove. Finally, the rear roller 3 compacts the soil. During the movement of the device, the seaweed seed rope 10 is continuously buried into the seabed. Under the tension of the buried seaweed seed rope 10, the winding reel 11 rotates to release the seaweed seed rope 10, and the device completes continuous sowing.

[0081] Step 3: Stop Sowing: When the operator pushes the sowing device to the preset position and needs to stop, stop pushing the sowing device, use a long-handled shovel to insert into the seabed and cut the seaweed seed rope 10, thus completing the sowing action of the seaweed seed rope 10 on the seabed. Repeat steps 2 and 3 when sowing is needed again.

[0082] The aforementioned sowing method using a seeding device involves laying seaweed seed ropes 10 in the furrows dug by the plow blades 13, then covering and compacting the soil. The seeds are accurately buried under the seabed and are not easily washed away by seawater. This seeding device achieves continuous sowing from furrowing to sowing to covering and compacting, resulting in high construction efficiency.

[0083] This utility model provides a hand-push seaweed seed sowing device, which is used for sowing seaweed seed rope 10. By setting up a push rod support box 5 and a connecting rod 6, the tilt angle of the push rod 7 can be quickly adjusted in multiple stages, allowing operators of different heights to push the device in a comfortable and effortless manner. This greatly improves the user experience and ease of operation, and reduces labor intensity. The device has a simple structure and is easy to move and operate in complex environments such as tidal flats and shallow water, providing an effective and specialized tool for seabed sowing.

[0084] By setting the connecting rod 6, the angle of the push rod 7 is kept stable and reliable during the sowing process, preventing accidental slippage and ensuring operational stability and sowing quality.

[0085] By setting up a winding device (winding reel 11 and reel support 12), the orderly storage and automatic feeding of seaweed seed rope 10 are achieved. This avoids the problems of rope tangling, knotting, or uneven feeding caused by manual reel holding, ensuring the continuity and stability of the sowing process and improving sowing efficiency.

[0086] By setting a 90° bend in the threading tube 9, the seaweed seed rope 10, which was guided vertically, is transformed into a horizontally directed output, thereby accurately placing the seed rope on the seabed surface at a predetermined depth instead of scattering it randomly, thus improving the accuracy and consistency of sowing.

[0087] By setting multiple guide rings 8 to form a guide path from the winding reel 11 to the threading tube 9, the movement range of the seaweed seed rope is effectively constrained, preventing it from swinging randomly in front of the push rod 7, further avoiding tangling and friction wear, and ensuring that the seed rope can be smoothly and with low resistance delivered to the threading tube.

[0088] By setting the L-shaped plow blade 13, a regular trench can be effectively opened in the seabed mud, ensuring that trenching is carried out before sowing, so that the seaweed seed rope 10 can fall accurately into the bottom of the trench, creating conditions for subsequent covering and compaction, which is conducive to seed germination and planting.

[0089] By using a soil-covering plate 14, the loose soil turned up by the plow blade 13 during furrowing is pushed back into the furrow, covering the seaweed seed rope 10. The design of the soil-covering plate 14, with its bottom edge flush with the lowest point of the roller 3, ensures that the soil-covering plate 14 effectively levels the soil without inserting too deeply into the mud and causing excessive resistance. Working in conjunction with the rear roller 3, it compacts the soil, completing the entire agronomic process of furrowing, sowing, covering, and compacting, simulating an optimal sowing environment and improving seed survival rate.
