Description

Technical Field

[0001] This utility model belongs to the field of seaweed sowing technology, and in particular relates to a handheld tool for sowing seaweed seed ropes. Background Technology

[0002] Seagrass is the only type of higher angiosperm on Earth that can live entirely in seawater. Composed of leaves, rhizomes, and roots, it inhabits tropical and temperate nearshore waters or estuarine areas, growing on silty or sandy sediments. It is another important marine ecosystem after mangroves and coral reefs. Large, contiguous areas of seagrass, known as seagrass beds, are habitats for many large marine organisms and even mammals, holding significant ecological importance. However, due to human activities, seagrass beds have suffered extensive shrinkage and destruction, necessitating seagrass planting to restore them and improve this situation.

[0003] However, seagrass cultivation currently relies mainly on manual planting at low tide. This method has a short planting time (short duration of low tide), high labor costs, a high risk factor, and limited planting area (far from the shore), resulting in high costs and low efficiency in seagrass cultivation.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] This utility model provides a handheld tool for sowing seaweed seed ropes, including a support rod, a seed rope reel, a base, and rollers. The seed rope reel is fixed to the upper end of the support rod, and the lower end of the support rod is hinged to the base. A sowing component is arranged on the center line of the base, which is aligned with the forward direction of the handheld tool. The sowing component includes a plowing component, a line-laying tube, and a soil-covering component arranged from front to back. The seaweed seed rope is wound around the seed rope reel, and its lower end passes through the line-laying tube until it exits from the lower end of the line-laying tube and is buried in the seabed. Two rollers are provided, located at the front and rear ends of the base, respectively. The rolling direction of the rollers is the forward direction of the handheld tool. During sowing, the plowing component opens a trench on the seabed, the seaweed seed rope enters the trench, the soil-covering component covers the trench with soil, and the roller located at the rear end of the base compacts the soil, thus completing the sowing.

[0009] Furthermore, the support rod includes a straight rod and an inverted U-shaped connecting rod fixed to the lower end of the straight rod. The two ends of the opening of the inverted U-shaped connecting rod are respectively hinged to the two side plates of the base.

[0010] Furthermore, the angle between the support rod and the base is locked by a positioning assembly. Two positioning assemblies are provided and symmetrically located on both sides of the handheld tool with the straight rod as the axis of symmetry. The positioning assembly includes a pull rope, a movable block, and a gear shift plate. The pull rope passes through the straight rod, with its upper end protruding from the upper end of the straight rod and being able to be pulled. Its lower end protrudes from the lower end of the straight rod and is fixed to the movable block. A sliding magazine is fixed above the hinge point of the inverted U-shaped connecting rod and the base. The movable block includes a slider and an insert block. The slider and the insert block are fixed together by a connecting post. The slider is limited to the sliding magazine. A compression spring is sleeved on the connecting post, and its upper and lower ends abut against the lower end of the sliding magazine and the upper end of the insert block, respectively. The pull rope controls the slider to slide in the sliding magazine. The gear shift plate is fixed to the outside of the side plate. The gear shift plate has multiple gear shift slots for insert blocks to be inserted to fix the angle between the support rod and the base.

[0040] 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.

[0041] like Figure 1-10 As shown, this utility model provides a handheld tool for sowing seaweed seeds with rope, such as... Figure 1 , Figure 2 As shown, the tool includes a support rod 1, a seed rope reel 2, a base 3, and rollers 4. The seed rope reel 2 is fixed to the upper end of the support rod 1, and the seaweed seed rope is wound around the seed rope reel 2. A waterproof sealed bearing is installed at the axis of the seed rope reel 2 to prevent seawater from splashing in and affecting the smoothness of the rotation of the seed rope reel 2. The lower end of the support rod 1 is hinged to the base 3 to improve operating comfort. There are two rollers 4, located at the front and rear ends of the base 3 respectively. The rolling direction of the rollers 4 is the forward direction of the handheld tool.

[0042] Specifically, such as Figure 1-3 , Figure 7As shown, the support rod 1 includes a straight rod 11 and an inverted U-shaped connecting rod 12 fixed to the lower end of the straight rod 11. The two ends of the opening of the inverted U-shaped connecting rod 12 are respectively hinged to the two side plates 31 of the base 3.

[0043] To ensure operational stability, such as Figure 1-4 , Figure 7-10 As shown, the angle between the support rod 1 and the base 3 can be locked by the positioning component 6. There are two positioning components 6, which are symmetrically located on both sides of the handheld tool with the straight rod 11 as the axis of symmetry.

[0044] like Figure 3-4 , Figure 7-10 As shown, the positioning component 6 includes a pull rope 61, a movable block 62, and a gear plate 63. The pull rope 61 is threaded through the straight rod 11, with its upper end protruding from the upper end of the straight rod 11 and being able to be pulled. Its lower end protrudes from the lower end of the straight rod 11 and is fixed to the movable block 62. A sliding chamber 64 is fixed above the hinge point of the inverted U-shaped connecting rod 12 and the base 3. The movable block 62 includes a slider 621 and an insert 622. The slider 621 and the insert 622 are fixed together by a connecting post 623. The slider 621 is limited to the sliding chamber 64. A compression spring 65 is sleeved on the connecting post 623, and its upper and lower ends abut against the lower end of the sliding chamber 64 and the upper end of the insert 622, respectively. The pull rope 61 controls the slider 621 to slide in the sliding chamber 64. The gear plate 63 is fixed to the outside of the side plate 31. The gear plate 63 has multiple gear slots 631 for the insert 622 to be inserted to fix the angle between the support rod 1 and the base 3.

[0045] When adjusting the angle between the support rod 1 and the base 3, pull the pull rope 61 to disengage the insert 622 from the gear slot 631, rotate the support rod 1, align the insert 622 with the gear slot 631 corresponding to the desired angle, release the pull rope 61, and the insert 622 will be inserted into the corresponding gear slot 631 under the action of the compression spring 65, locking the support rod 1.

[0046] like Figure 1-6 As shown, a seeding component 5 is arranged on the center line of the base 3, which is aligned with the forward direction of the handheld tool. The seeding component 5 includes a plowing component 51, a line-laying tube 52, and a soil-covering component 53 arranged from front to back. The plowing component 51 is used to open trenches. The lower end of the seaweed seed rope passes through the lower end of the line-laying tube 52 and is buried in the seabed. The soil-covering component 53 is used to cover the trenches opened by the plowing component 51 with soil. The roller 4 allows the handheld tool to move easily while compacting the soil.

[0047] During sowing, as the hand-held tool moves forward, the plowing component 51 opens a trench on the seabed. The seaweed seed rope is passed through the lower end of the laying pipe 52 and laid in the trench. The soil covering component 53 covers the trench opened by the plowing component 51 with soil, and the roller 4 located at the rear end of the base 3 compacts the soil, thus completing the sowing.

[0048] Specifically, such as Figure 5 As shown, the plow assembly 51 includes two coaxially rotating plow blades 511 with an adjustable angle. The angle between the two plow blades 511 can be adjusted from 0° to 180°. Different angles can adapt to different seabed textures, such as sandy, muddy, and gravelly textures, ensuring that the trench width matches the specifications of the seaweed seed rope to meet the needs of seaweed planting in different marine environments. The two plow blades 511 are located below the base plate 32 of the base 3. The upper ends of the rotating shafts of the two plow blades 511 extend upward through the base plate 32 and are respectively connected to a first gear 512 and a second gear 513. A rack groove 514 is fixed on the base plate 32, and a rack plate 515 is slidably arranged in the rack groove 514. The first gear 512 and the second gear 513 mesh with the racks on both sides of the rack plate 515, respectively. A locking hole 5151 is provided on the rack plate 515 to lock the rack plate 515 into the rack groove 514.

[0049] When adjusting the included angle of the two plow blades 511, the rack plate 515 slides in the rack groove 514. When the rack plate 515 slides, it will drive the first gear 512 and the second gear 513 to rotate in opposite clockwise directions at the same time. The first gear 512 and the second gear 513 will drive the two plow blades 511 to rotate in opposite clockwise directions at the same time to open and close until the target angle is adjusted. Then, the locking pin 516 is inserted into the locking hole 5151 to lock the rack plate 515.

[0050] It is important to note that the first gear 512 and the second gear 513 are identical, as are the racks on both sides of the rack plate 515. Thus, when the first gear 512 and the second gear 513 rotate simultaneously in opposite clockwise directions, the amount of rotation is the same, thereby causing the two plowshares 511 to adjust at the same angle, ensuring that the included angle between the two plowshares 511 is symmetrical about the direction of the handheld tool's movement.

[0051] like Figure 4 As shown, the line-laying tube 52 is located on the axis of symmetry of the two plow blades 511. The upper end of the line-laying tube 52 is vertically inserted into the base plate 32, and the lower end is bent backward into a horizontal shape so that the seaweed seed rope can be laid flat in the groove opened by the plowing assembly 51 after it passes through the lower end of the line-laying tube 52.

[0052] like Figure 6As shown, the cover plate assembly 53 includes two forward-opening cover plates 531 located below the base plate 32. Worm gears 532 are fixed to the upper ends of the two cover plates 531, positioned above the base plate 32. The worm gears 532 mesh with a worm 533. Tightening the worm 533 causes the worm gears 532 to rotate the cover plates 531 around the axis of the worm gears 532, adjusting the angle between the cover plates 531 and the seabed. This allows for adjustment of the angle between the cover plates 531 and the seabed according to the seabed slope and the required cover volume, ensuring uniform cover coverage. The angle between the cover plates 531 and the seabed ranges from 30° to 60°.

[0053] It is important to note that the bottom of the plow blade 511 is lower than the bottom of the roller 4 to ensure that the plowing assembly 51 can create trenches on the seabed when the hand-held tool is moved along the seabed. The bottom of the laying tube 52 is flush with the bottom of the plow blade 511 to ensure that the seaweed seed rope pulled out from the laying tube 52 is positioned within the trench created by the plowing assembly 51 on the seabed. When the covering plate 531 forms a 90° angle with the seabed, the bottom of the covering plate 531 is flush with the bottom of the roller 4 to ensure that the trench created by the plowing assembly 51 is leveled.

[0054] Preferably, such as Figure 1-4 As shown, the roller 4 is hollow, and multiple through holes 41 for water injection and drainage are provided on its outer wall. When not in use, the hollow roller 4 reduces the overall weight of the handheld tool, making it easier to carry. When in use, when the handheld tool is submerged in seawater, seawater flows into the roller 4 through the through holes 41, increasing the weight of the roller 4 to ensure the overall stability of the handheld tool and to compact the soil.

[0055] In addition, the surface of roller 4 is provided with anti-slip textures such as serrations or grids to enhance the grip of roller 4 on soft or muddy seabeds, prevent slippage and improve compaction effect.

[0056] Preferably, such as Figure 1-2 As shown, the support rod 1 is equipped with multiple guide members 7 to guide the seaweed seed rope, reducing the impact of seawater and the displacement caused by debris in the seawater. The multiple guide members 7 are arranged in the same direction from top to bottom. Both ends of the guide members 7 are trumpet-shaped, and the material is selected as wear-resistant ceramic or polymer material such as UHMWPE to reduce friction between the seaweed seed rope and the guide members 7, thus reducing wear on the seaweed seed rope. Furthermore, the guide members 7 are formed by two identical arc-shaped pieces 71 that can be detachably fastened together, allowing for quick installation of the seaweed seed rope into the guide members 7.

[0057] like Figure 1-2 As shown, a depth scale 8 is installed on the base plate 32 to display the depth of the handheld tool inserted into the sea surface in real time, which makes it easy for operators to make precise adjustments according to the needs of seaweed planting.

[0058] Preferably, the support rod 1, base 3, roller 4 and seeding assembly 5 are all made of corrosion-resistant materials such as 316 stainless steel or have a marine-grade anti-corrosion coating applied to the surface to extend their service life in high-salt seawater environments.

[0059] It should be noted that in this utility model, "front" refers to the forward direction of the handheld tool, and "rear" refers to the direction opposite to the forward direction of the handheld tool.

[0060] Working principle: Before operation, the seed rope reel 2, wrapped with seaweed seed rope, is installed on the support rod 1. The seaweed seed rope is then passed sequentially through multiple guide pieces 7 and the laying pipe 52. The angle between the two plow blades 511, the angle between the cover plate 531 and the seabed, and the angle between the support rod 1 and the base 3 are adjusted. The operator enters the work area with the adjusted hand tools, pulls a section of the seaweed seed rope from the lower end of the laying pipe 52 and fixes it to the seabed, then inserts the plow blades 511 into the seabed until the two rollers 4 contact the seabed. Subsequently, the operator pushes the straight rod 11, at which point the base 3 moves forward with the rotation of the rollers 4, and the plowing assembly 51 opens a trench forward. Because the tail end of the seaweed seed rope is fixed to the seabed, it pulls the seed rope reel 2 to rotate, continuously laying the rope. Since the laying pipe 52 is located in the middle of the plow blades 511, it allows the seaweed seed rope to be laid in the trench. The soil covering component 53 then re-covers the soil from both sides of the trench into the trench, and the rollers 4 compact it. After the operation is completed, simply cut the seaweed seed rope.
