Description

Technical Field

[0001] This utility model relates to the field of submerged plant sowing technology, specifically a device for uniformly sowing submerged plants. Background Technology

[0002] Submerged plants play a vital role in aquatic ecosystem restoration and water purification, particularly in stagnant water bodies, wetland ecosystems, and water pollution control. They not only effectively absorb nutrients from the water, reducing the risk of eutrophication, but also provide habitats for aquatic organisms, improve light conditions, and promote healthy ecological cycles. Therefore, submerged plant cultivation techniques are widely used in environmental engineering and water treatment, especially in projects such as river management, lake restoration, and constructed wetland development.

[0003] Currently, the main methods for cultivating submerged plants include natural sowing, artificial seeding, and cutting propagation. Among these, seeding by direct sowing is the most commonly used method due to its simplicity, low cost, and strong adaptability. Especially in still or shallow water bodies, seeds of submerged plants are placed on the bottom by direct sowing, where they naturally sink and germinate under suitable conditions. For some submerged plants, such as *Ceratophyllum demersum* and *Potamogeton crispus*, this method allows seeds to be placed directly on the water surface, where they naturally sink and their roots grow downwards, thus completing the planting process.

[0004] However, existing seed-throwing methods still have some significant technical bottlenecks and shortcomings, specifically in the following aspects:

[0005] (1) Uneven seeding:

[0006] Currently, seeding operations typically rely on manual labor or traditional machinery. When seeding manually, workers stand on a seeding boat and manually release submerged plants into the water. Due to human error, the height, force, and angle of the seed release are difficult to maintain consistently, resulting in uneven seed distribution. Some seeds may even float on the surface due to improper release angles, failing to sink to the bottom or distributing unevenly after sinking, thus affecting plant growth and development.

[0007] (2) Physical exertion and low efficiency:

[0008] In manual seeding, workers need to stand for long periods and throw seeds, and the throwing height and angle often need to be adjusted based on experience. This high-intensity labor gradually depletes the workers' physical strength, affecting the continuity and stability of the operation, ultimately leading to unstable seeding results and reduced efficiency and accuracy. Especially in large-scale water management, the efficiency of manual seeding is insufficient to meet the needs of rapid and large-scale vegetation restoration.

[0009] (3) Insufficient adaptability to water characteristics and seed characteristics:

[0010] Current direct seeding methods are primarily suitable for aquatic environments with soft, sandy bottoms. However, in water environments with hard, muddy bottoms or lacking soft sediment (such as some rivers and artificial lakes), submerged plant seeds are difficult to sink naturally and are easily affected by water currents or wind, causing them to float, drift, or fail to reach their intended location accurately. Furthermore, for some more fragile plant seeds, such as *Hydrilla verticillata* and *Elodea nuttallii*, traditional direct seeding methods can easily damage the seeds, affecting their germination and survival rates.

[0011] (4) Low level of mechanization and insufficient level of automation:

[0012] Although some mechanized seed-throwing equipment has emerged, most of it still relies on manual control and lacks a high degree of automation and precision. This makes existing equipment less adaptable to complex water conditions, different plant species, and varying environmental conditions, making it difficult to achieve efficient, accurate, and continuous seed-throwing operations.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) This invention automatically sows submerged plants by pouring them into the hopper, allowing them to fall onto the transmission belt.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Example 1: Please refer to Figure 1-10 This utility model provides a technical solution: a device for uniformly distributing seeds of submerged plants, including a seed-distributing boat 1; multiple guide frames 2 are slidably installed on the seed-distributing boat 1, a seed-distributing structure is installed on the guide frames 2, a support plate 3 is installed on the seed-distributing structure, an anti-blocking structure is installed on the support plate 3, a driving structure is installed on the seed-distributing boat 1, and an adjusting screw 5 is fixedly installed on the inner wall of the seed-distributing boat 1, with an adjusting structure installed on the adjusting screw 5;

[0045] The seeding structure includes a first drive wheel 21 and a second drive wheel 22, both of which are rotatably mounted on the inner wall of the guide frame 2. The same drive belt 23 is driven onto the first drive wheel 21 and the second drive wheel 22. Multiple partition plates 24 are fixedly mounted on the drive belt 23. A hopper 25 is fixedly mounted on the guide frame 2 and is connected to the guide frame 2. The hopper 25 is located on the top side of the drive belt 23. Submerged plants are placed into the hopper 25 so that they fall onto the drive belt 23 inside the guide frame 2, placing them between two corresponding partition plates 24. At the same time, the drive motor 4 can be turned on, causing the drive belt 23 to rotate. The rotating drive belt 23 drives the partition plates 24 to move, causing the moving partition plates 24 to throw the submerged plants from the guide frame 2 into the river, thus completing the seeding of the submerged plants.

[0046] Furthermore, the anti-clogging structure includes a vibration motor 31, which is fixedly installed on the top side of the support plate 3. The support plate 3 is located on one side of the hopper 25. By turning on the vibration motor 31, it can generate vibration, which in turn drives the hopper 25 to vibrate through the support plate 3, thus preventing the submerged plants in the hopper 25 from becoming clogged.

[0047] Furthermore, the drive structure includes a drive motor 4, which is fixedly mounted on the seed-throwing vessel 1. A first pulley 41 is fixedly mounted on the output end of the drive motor 4. A transmission belt 42 is driven onto the first pulley 41, and a second pulley 43 is driven onto the transmission belt 42. A drive shaft 44 is fixedly mounted on one side of the second pulley 43. The drive shaft 44 is rotatably mounted on the inner wall of the seed-throwing vessel 1 and slidably mounted on the guide frame 2. Two linkage sliders 45 are fixedly mounted on the inner wall of the second transmission wheel 22. Both linkage sliders 45 are slidably mounted on the drive shaft 44, which can activate the drive motor 4 to drive the seed-throwing vessel 1. The output of the motor 4 drives the first pulley 41 to rotate. The rotating first pulley 41 can drive the second pulley 43 to rotate through the transmission engagement with the transmission belt 42. In turn, the second pulley 43 drives the drive shaft 44 to rotate within the two positioning holes 47, thereby preventing the drive shaft 44 from deviating. The continuously rotating drive shaft 44 will drive the second transmission wheel 22 to rotate through the engagement of the adjusting slide 46 and the linkage slider 45. Through the transmission engagement of the second transmission wheel 22 with the first transmission wheel 21 and the transmission belt 23, the first transmission wheel 21 can rotate simultaneously, and the transmission belt 23 can make a circular motion.

[0048] Furthermore, two adjustment grooves 46 are provided on the drive shaft 44, and two linkage sliders 45 are slidably installed in the two adjustment grooves 46 respectively. When the second transmission wheel 22 slides, it can drive the two linkage sliders 45 to slide in the two adjustment grooves 46 on the drive shaft 44 respectively, so that the drive shaft 44 will not interfere with the movement of the second transmission wheel 22.

[0049] Furthermore, the seed-throwing vessel 1 has two positioning rotating holes 47. The two ends of the drive shaft 44 are respectively rotatably installed in the two positioning rotating holes 47. The second pulley 43 can drive the drive shaft 44 to rotate in the two positioning rotating holes 47, thereby preventing the drive shaft 44 from shifting.

[0050] Furthermore, the guide frame 2 is provided with a connecting hole 26, which is connected to the hopper 25, providing space for submerged plants to pass through.

[0051] Example 2: Figure 1-10 To adjust the density of the guide frame 2, an adjustment structure is arranged on the adjusting screw 5. The adjustment structure includes an adjusting ring 51, which is rotatably mounted on one side of the guide frame 2. Two handles 52 are fixedly mounted on the adjusting ring 51. An adjusting screw hole 53 is formed on the inner wall of the adjusting ring 51, and the adjusting screw 5 is threaded into the adjusting screw hole 53. An annular limiting groove 54 is formed on the inner wall of the guide frame 2, and a limiting ring 55 is rotatably mounted within the annular limiting groove 54. The limiting ring 55 is fixedly mounted on one side of the adjusting ring 51. An adjusting hole 56 and a sliding hole 57 are formed on the inner wall of the guide frame 2, and the adjusting screw 5 is slidably mounted in the adjusting hole 56. The drive shaft 4... 4. The guide frame 2 is installed in the sliding hole 57. A guide groove 58 is opened on the bottom side of the guide frame 2. A guide plate 59 is slidably installed in the guide groove 58. The guide plate 59 is fixedly installed on the inner wall of the seed-throwing boat 1. By turning the handle 52, the adjusting ring 51 can be driven to rotate. The rotating adjusting ring 51 can move on the adjusting screw 5 through the threaded engagement of the adjusting screw hole 53 and the adjusting screw 5. The moving adjusting ring 51 then drives the guide frame 2 to move through the engagement of the limiting ring 55 and the annular limiting groove 54, thereby adjusting the seeding density of the submerged plants by the guide frame 2 so as to adjust according to the size of the river and the environmental conditions. The remaining features are the same as in Example 1.

[0052] The working principle is as follows: Submerged plants are placed into the hopper 25. A connecting hole 26 provides space for the plants to pass through, allowing them to fall onto the transmission belt 23 within the guide frame 2. This positions the plants between the corresponding two partition plates 24. Simultaneously, the drive motor 4 is activated. The output of the drive motor 4 drives the first pulley 41 to rotate. The rotating first pulley 41, through its interaction with the transmission belt 42, drives the second pulley 43 to rotate. This, in turn, causes the second pulley 43 to drive the drive shaft 44 to rotate between the two positioning holes. The drive shaft 44 rotates within 47 to prevent it from shifting. The continuously rotating drive shaft 44, through the adjustment of the sliding groove 46 and the linkage slider 45, drives the second transmission wheel 22 to rotate. Through the transmission cooperation of the second transmission wheel 22, the first transmission wheel 21, and the transmission belt 23, the first transmission wheel 21 rotates simultaneously, causing the transmission belt 23 to perform circular motion. This circular motion of the transmission belt 23 drives the partition plate 24 to move, causing the moving partition plate 24 to throw the submerged plants from the guide frame 2 into the river, completing the sowing of the submerged plants. By setting multiple sets of guide frames 2 and transmission belts 23, the efficiency of sowing submerged plants can be further improved. Turning the handle 52 rotates the adjusting ring 51, which in turn rotates the limiting ring 55 within the annular limiting groove 54, thus preventing the adjusting ring 51 from shifting. The continuously rotating adjusting ring 51 moves along the adjusting screw 5 through the threaded engagement of the adjusting screw hole 53 and the adjusting screw 5. The moving adjusting ring 51 then moves the guide frame 2 through the engagement of the limiting ring 55 and the annular limiting groove 54, allowing the guide frame 2 to move. The guide frame 2 can slide on the adjusting screw 5 through the adjusting hole 56, and at the same time, it slides on the drive shaft 44 through the sliding hole 57 and drives the internal second transmission wheel 22 to move. The continuously moving guide frame 2 can slide on the guide plate 59 through the guide groove 58, thereby restricting the movement direction of the guide frame 2 and preventing it from deviating. By moving the position of the guide frame 2, the distance between two adjacent guide frames 2 can be adjusted, thereby adjusting the seeding density of submerged plants by the guide frame 2, so as to adjust according to the size of the river and the environmental conditions.

[0053] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
