Seagrass beds have extremely high productivity and are habitats, feeding grounds, and nursery grounds for marine organisms. They also have the function of weakening waves and currents. However, due to factors such as climate change, storm surges, environmental pollution, diseases, animal feeding, and interspecies competition, the global seagrass beds are decreasing at a rate of 7% per year.

[0036] The rotation of the winding wheel 7 drives the spiral guide rail 8 to rotate, and the spiral guide rail 8 drives the driving plate 12 to rotate downward through the spiral groove and the driving column 13, so that the driving plate 12 drives the third rotating shaft to rotate, and the third rotating shaft drives the feeding tube 20 to move close to the winding wheel 7 through the material storage box 15. When the spiral guide rail 8 rotates to the bottom, the discharge end of the feeding tube 20 abuts against the outer surface of the annular winding groove. At this time, the feeding tube 20 is connected to the through hole, and the bottom end of the square slide 23 is driven by the feeding tube 20 to abut against the top of the square countersunk hole on the surface of the annular winding groove. At this time, the power supply of the electromagnet 24 is turned on, so that the electromagnet 24 adsorbs the square iron block 25, and the first pull rope 2101 and the second pull rope 2202 are connected through this device.

[0037] In this embodiment, two third support plates 16 are symmetrically fixedly installed on the outer surface of the third rotating shaft near both ends, and a second rotating shaft 17 is rotatably installed between the two third support plates 16. The second rotating shaft 17 passes through the outer surface of the material storage box 15, and a plurality of feeding wheels 19 are equidistantly fixedly installed on the outer surface of the second rotating shaft 17. The feeding wheels 19 are arranged inside the front cavity of the material storage box 15, and a plurality of feeding grooves are equidistantly opened on the circumferential outer surface of the feeding wheel 19, and the feeding grooves are arranged below the discharge port.

[0039] In this embodiment, spiral guide rails 8 are fixedly installed on the outer surfaces of the winding wheels 7 near the two first support plates 5, and spiral grooves are opened on the outer surfaces of the spiral guide rails 8. Drive plates 12 are fixedly installed on the outer surfaces of the second support plates 14 at both ends of the third rotating shaft, and drive columns 13 are fixedly installed on the outer surface of the drive plates 12 near the bottom end.

[0040] By manually turning the knob 11, the knob 11 drives the worm 9 to rotate, the worm 9 drives the worm wheel 10 to rotate, the rotation of the worm wheel 10 drives the connecting shaft 6 to rotate, the connecting shaft 6 drives multiple winding wheels 7 to rotate, and the rotation of the winding wheel 7 releases the conveying tube 701 from the annular winding groove, so that the conveying tube 701 drives the elliptical seeding block 703 along the guide roller 4 to fall to the surface of the seabed. At the same time, the rotation of the winding wheel 7 drives the spiral guide rail 8 to rotate, and the spiral guide rail 8 drives the drive plate 12 to rotate downward through the spiral groove and the drive column 13.

[0041] In this embodiment, the width of the annular winding groove is set to match the diameter of the conveying pipe 701 , and the pitch of the spiral groove is set to match the diameter of the conveying pipe 701 .

When the conveying tube 701 is rolled up, the connecting plate 702 will slide into the interior of the opening 2 to accommodate the elliptical seeding block 703 in the interior of the opening 2. The second connecting rod 706 and the first connecting rod 705 are used to limit the position of the elliptical seeding block 703 from rotating and always maintain a vertical state, which is convenient for the sowing of seaweed seed mud balls.

[0043] It should be noted that when the present invention is in use, the operator drives the hull 1 to the designated seabed position. It should be noted that the speed of the hull 1 is as required to avoid dragging the elliptical seeding block 703 too fast. Then the seaweed seed mud balls are poured into the front cavity of the storage box 15. The amount of seaweed seed mud balls added cannot be higher than the feeding groove at the top of the feeding wheel 19, so that the feeding wheel 19 can receive the material. The knob 11 is manually turned to make the knob 11 drive the worm 9 to rotate, and the worm 9 drives the worm wheel 10 to rotate. The rotation of the worm wheel 10 drives the connecting shaft 6 to rotate, and the connecting shaft 6 drives multiple winding wheels 7 to rotate. The rotation of the winding wheel 7 releases the conveying pipe 701 from the annular winding groove The elliptical seeding block 703 is released, so that the conveying pipe 701 drives the elliptical seeding block 703 along the guide roller 4 to fall into the surface of the seabed. Due to the weight of the elliptical seeding block 703 itself, after falling into the surface of the seabed, it will sink to a depth of 2-3cm inside the soil of the seabed. At this time, the discharge end of the seeding hole inside the elliptical seeding block 703 is located on the upper surface of the seabed. The elliptical seeding block 703 is dragged by the hull 1 to move along the surface of the seabed, so that the elliptical seeding block 703 scratches a pit with a depth of 2-3cm on the surface of the seabed, and the seaweed seed mud balls are sown into the pit. At the same time, the spiral guide rail 8 is driven to rotate by the rotation of the winding wheel 7, and the spiral guide rail 8 drives the driving plate 12 to rotate downward through the spiral groove and the driving column 13. The driving plate 12 drives the third rotating shaft to rotate, and the third rotating shaft drives the feeding tube 20 to move close to the winding wheel 7 through the material storage box 15. When the spiral guide rail 8 rotates to the bottom, the discharge end of the feeding tube 20 abuts against the outer surface of the annular winding groove. At this time, the feeding tube 20 is connected to the through hole, and the bottom end of the square slide 23 is driven by the feeding tube 20 to abut against the top of the square countersunk hole on the surface of the annular winding groove. At this time, the power supply of the electromagnet 24 is turned on, so that the electromagnet 24 adsorbs the square iron block 25, and the first pull rope 2101 and the second pull rope 2202 are connected through this device. When the partial elliptical seeding block 703 is dragged to the upper surface of the rock on the seabed surface, or the seabed surface When the mud layer is shallow, the sinking distance of the elliptical sowing block 703 is small. At this time, the pressure plate 704 is not lifted up by the mud layer and is still in the initial position. At this time, the rotating rod 708 does not rotate, and the first pull rope 2101 and the second pull rope 2202 will not pull the scraper 29 to open the discharge port. The seaweed seed mud balls inside the feeding trough on the surface of the feeding wheel 19 will be scraped back into the front cavity of the storage box 15 by the scraper 29 and will not fall into the rear cavity of the storage box 15. Through this device, when sowing seaweed seed mud balls, when encountering a seabed with a shallow mud layer or a rock layer on the seabed surface, seaweed seeds will not be sown, thereby avoiding the waste of seaweed seeds and reducing the cost of seaweed bed ecological restoration.When the elliptical sowing block 703 has sunk far enough, the pressing plate 704 is lifted up by the mud layer, which drives the rotating rod 708 to rotate. The rotating rod 708 reels the second pull rope 2202 so that the first pull rope 2101 pulls up the scraper 29. At this time, the discharge port on the partition is fully opened, and the seaweed seed mud balls fall into the inside of the feeding pipe 20, and fall into the mud pit on the seabed through the conveying pipe 701 and the sowing hole. The mud is re-covered on the surface of the seaweed seed mud balls by the pressing plate 704 to prevent them from being eaten by fish and shrimp in the sea. The second rotating shaft 17 is driven to rotate by the driving motor 18, so that the second rotating shaft 17 drives the feeding wheel 19 to rotate, and the feeding wheel 19 transports the seaweed seed mud balls to the rear cavity of the storage box 15 through the feeding trough on the surface, which is convenient for subsequent planting. ;
