Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology in mining areas, and in particular to a plant root protection device for ecological restoration of manganese tailings ponds. Background Technology

[0002] While manganese mining and smelting bring economic benefits, they also cause numerous environmental problems. In particular, the tailings from mining and beneficiation, or the electrolytic manganese slag from acid leaching, are landfilled in tailings ponds, occupying large amounts of land and causing a series of heavy metal pollution issues. This has become a pressing problem that needs to be addressed. Currently, compared to traditional physical and chemical remediation technologies, phytoremediation technology is a more economical, environmentally friendly, aesthetically pleasing, and stable in-situ remediation technology, and is widely used in the remediation of heavy metal tailings ponds.

[0003] However, the ecological restoration of manganese tailings ponds has consistently faced challenges such as high heavy metal content in the tailings slag, harsh soil conditions, difficulty in water retention, and the difficulty in achieving good growth or survival of manganese-tolerant plants even when directly planted. Therefore, protecting the roots of plants in direct contact with the tailings during the ecological restoration process would be more beneficial for plant growth. However, existing protective devices primarily provide support for seedlings, offering limited protection and are not suitable for the harsh soil environments of manganese tailings ponds, thus failing to effectively address the problems encountered in the ecological restoration of manganese tailings ponds.

[0004] Based on this, a plant root protection device for ecological restoration of manganese tailings ponds is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a plant root protection device for ecological restoration of manganese tailings ponds, so as to solve the problems faced in the ecological restoration process of manganese tailings ponds and the problems existing in the prior art. It can protect plant roots and adapt to the plants, providing support and protection for the seedlings, thus achieving the purpose of dual protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a plant root protection device for ecological restoration of manganese tailings ponds, comprising a first bottom ring, a fixing cone, a second bottom ring, and geotextile. The bottom ends of the first and second bottom rings are both connected to the fixing cone, and the top ends of the first and second bottom rings are both connected to a support frame. The upper inner side of the support frame is provided with an outer support hoop and an inner support hoop, which are connected by an adjusting seat. The lower inner side of the support frame is fixed with a limit block. The top ends of the first and second bottom rings are both connected to a pressure plate, and geotextile is connected between the pressure plate and the first and second bottom rings. The bottom end of the geotextile extends below the first and second bottom rings.

[0008] Furthermore, a spring is fixed to one side of the inside of the adjusting seat, and an adjusting rod is connected to the other side of the spring. The other side of the adjusting rod is connected to the inner support hoop.

[0009] Furthermore, the width of the adjusting rod matches the internal width of the adjusting seat.

[0010] Furthermore, both the outer support hoop and the inner support hoop are provided in two sets, and the two sets of the outer support hoop are fixedly connected by bolts.

[0011] Furthermore, each of the pressure plates has through holes inside, which are movably connected to the lower end of the support frame.

[0012] Furthermore, a threaded rod is connected to the top of the pressure plate, and the threaded rod is threadedly connected to the inside of the limiting block.

[0013] Furthermore, a knob is fixed to the top of the threaded rod, and the outer side of the knob is provided with anti-slip texture.

[0014] Furthermore, the geotextile is a non-woven fabric or a geotextile mat.

[0015] Compared with the prior art, the beneficial effect of this utility model is that the plant planting root protection device for ecological restoration of manganese tailings ponds achieves a dual protection function.

[0016] By fixing the first and second bottom rings outside the planting pit, laying geotextile inside the pit, and then sequentially filling it with microbial fertilizer, planting soil, more microbial fertilizer, and planting plants, the roots of the seedlings are protected. This not only isolates the plant roots from direct contact with manganese tailings slag, ensuring normal growth of the plants during the seedling establishment and early growth stages, but also prevents excessive water leakage, improving water retention. Furthermore, the geotextile material can be penetrated by plant roots without affecting root growth. In addition, the support frame, outer support hoop, and inner support hoop provide support and protection for the seedlings. The adjusting seat, spring, and adjusting rod allow the device to adapt to plant growth, enhancing its practicality and flexibility, ultimately achieving the dual protection objective.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figures 1-5 The present invention provides the following technical solution: Example 1

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the plant root protection device for ecological restoration of manganese tailings ponds provided by this utility model includes a first bottom ring 8, a fixing cone 9, a second bottom ring 15, and geotextile 10. The bottom ends of the first bottom ring 8 and the second bottom ring 15 are both connected to the fixing cone 9. The top ends of the first bottom ring 8 and the second bottom ring 15 are both connected to the support frame 4. The upper inner side of the support frame 4 is provided with an outer support hoop 1 and an inner support hoop 2. There are two sets of outer support hoop 1 and inner support hoop 2. The two sets of outer support hoop 1 are fixedly connected by bolts. The outer support hoop 1 and the inner support hoop 2 are connected by an adjusting seat 3. A spring 11 is fixed on one side inside the adjusting seat 3. An adjusting rod 12 is connected to the other side of the spring 11. The other side of the adjusting rod 12 is connected to the inner support hoop 2. The width of the adjusting rod 12 matches the internal width of the adjusting seat 3.

[0027] In this embodiment, the plant seedlings are supported by the support frame 4, the outer support hoop 1 and the inner support hoop 2 to prevent the plant seedlings from tilting or falling over after planting. At the same time, during the subsequent growth of the plant, the adjustment seat 3, the spring 11 and the adjustment rod 12 can adapt to the growth of the plant without affecting the plant seedlings, thus enhancing the practicality and flexibility of the device and providing support and protection for the plant seedlings. Example 2

[0028] This embodiment, based on embodiment 1, achieves dual protection by protecting the root, specifically as follows: Figure 1 , Figure 4 and Figure 5As shown, a limit block 6 is fixed to the inner side of the lower end of the support frame 4. A pressure plate 7 is connected to the top of the first bottom ring 8 and the second bottom ring 15. A geotextile 10 is connected between the pressure plate 7 and the first bottom ring 8 and the second bottom ring 15. The bottom end of the geotextile 10 extends to the bottom of the first bottom ring 8 and the second bottom ring 15. A through hole 14 is provided inside the pressure plate 7, which is movably connected to the lower end of the support frame 4. A threaded rod 13 is connected to the top of the pressure plate 7. The threaded rod 13 is threadedly connected to the inside of the limit block 6. A knob 5 is fixed to the top of the threaded rod 13. The outer side of the knob 5 is provided with anti-slip texture. The geotextile 10 is a non-woven fabric or geotextile felt pad.

[0029] In this embodiment, rotating the knob 5 drives the threaded rod 13 to rotate. Under the action of the through hole 14, the limiting block 6, and the threaded connection, the pressure plate 7 can be flexibly raised, lowered, and guided, facilitating the loading and unloading of the geotextile 10. Furthermore, after the plant seedlings no longer require support and protection, the entire device can be removed and reused without removing the geotextile 10. During use, the geotextile 10 is fixed and laid in the planting pit, followed by the sequential filling of microbial fertilizer, planting soil, and planting of plants. During plant ecological restoration, protecting the plant roots that are in direct contact with manganese tailings slag is more conducive to the subsequent normal growth of the plants. It can directly isolate the plant roots from contact with manganese tailings slag, ensuring normal growth of the plants during the seedling establishment and early growth stages. It can also prevent excessive water leakage, improving water retention. As the plants grow, the non-woven fabric and geotextile felt material of the geotextile 10 can be pierced by the roots without affecting the growth of the plant roots, thus achieving root protection for the seedlings and achieving a dual protection purpose.

[0030] This utility model provides a plant root protection device for ecological restoration of manganese tailings ponds. Before use, the planter selects a geotextile 10 of appropriate size according to the size of the planting pit, adjusts the limiting block 6, threaded rod 13 and pressure plate 7 to install the geotextile 10 between the pressure plate 7 and the first bottom ring 8 and the second bottom ring 15. During use, the planter steps on the edges of the first bottom ring 8 and the second bottom ring 15 and inserts the fixing cone 9 into a suitable position outside the planting pit. Then, the geotextile 10 is laid in the planting pit, and then microbial fertilizer, planting soil and microbial fertilizer are filled into the planting pit in sequence, and plant seedlings are planted. The whole process is simple to operate, protects the plant roots and provides nutrients for the plants.

[0031] Secondly, after the plant seedlings are planted, the planters adjust the support frame 4 to a suitable position and connect and fix the outer support hoop 1. The inner support hoop 2 supports the plant seedlings, and the plant growth is adapted to the action of the adjusting seat 3, spring 11, and adjusting rod 12. This process is simple and provides support and protection for the plant seedlings.

[0032] Finally, the device is simple in structure, easy to use and can be reused multiple times. It is suitable for protecting plant seedlings when planting in harsh soil environments such as manganese tailings ponds. It can protect the plant roots and adapt to the plant, providing support and protection for the seedlings to achieve the purpose of dual protection.
