Description

Technical Field

[0001] The present invention relates to the technical field of land restoration, and in particular, to a construction device for comprehensive land improvement and ecological restoration. Background Art

[0002] Soil is originally a natural shelter and purification treatment site for various waste materials. The fact that soil accepts pollutants does not mean that the soil is polluted. Only when the various pollutants contained in the soil are excessive, affecting and exceeding the self-purification ability of the soil, and thus having a harmful impact in terms of hygiene and epidemiology, does it indicate that the soil is polluted. There are many reasons for soil pollution, such as industrial sludge, agricultural use of garbage, sewage irrigation, settlement of pollutants in the atmosphere, extensive use of mineral fertilizers and pesticides containing heavy metals, etc. Comprehensive land improvement and ecological restoration refer to using physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil, reducing their concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation can include: changing the existence form of pollutants in the soil or their binding mode with the soil, reducing their mobility and bioavailability in the environment; secondly, reducing the concentration of harmful substances in the soil. Currently, more chemical methods are used for contaminated soil remediation, that is, mixing a chemical remediation solution with the soil to degrade its pollutants through chemical reactions.

[0003] After retrieval, according to the patent network CN118489305B, a construction device for comprehensive land improvement and ecological restoration is disclosed, mainly relating to the technical field of storage devices, including a towing frame, a first harrow frame, a second harrow frame, notch discs, concave discs, and a spray pipe. A number of spray heads for cooperating with the notch discs and concave discs are provided on the spray pipe, and it also includes a first driving wheel for driving the spray pipe to rotate; the middle parts of the first harrow frame and the second harrow frame are rotatably arranged on the towing frame. A first adjusting block and a second adjusting block are slidably connected to the towing frame. Adjusting grooves are provided at the ends of the first harrow frame and the second harrow frame. First columns are respectively provided at both ends of the first adjusting block and the second adjusting block. It also includes a second driving wheel for driving the first adjusting block and the second adjusting block to slide. The beneficial effect of this invention lies in: solving the problem of uneven mixing of the chemical remediation solution and the soil, and improving the efficiency and effect of soil remediation.

[0004] However, when the existing soil remediation device is in use, although it can perform multi-directional adjustment operations on the remediation disc and the spraying angle of the remediation liquid, when the traction frame is connected to the tractor for movement, the convenience of moving the traction frame and the flat ground through the moving wheels is not high. Moreover, when the moving wheels assist the traction frame in transferring, the automatic rotary scraping and removal effect of the soil on the surface of the remediation disc is not high, and manual removal is required, increasing the workload of the users. In addition, if the surface of the remediation disc is not cleaned in a timely manner, the quality of subsequent land remediation will be reduced. Also, when the land is repaired and processed by the remediation disc, the adjustability of the use spacing between the harrow frames is not high, and the use spacing of the harrow frames cannot be adjusted according to the specific repair area and scope, reducing the flexibility of the overall use of the remediation device and not meeting the user's needs. Therefore, we propose a construction device for comprehensive land improvement and ecological restoration. Summary of the Invention
