Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and specifically to a device for improving soil water retention. Background Art

[0002] During the open-pit mining process, the original landforms and features are severely damaged. Mining rights holders implement the principle of equal emphasis on mineral resource development and environmental protection, and simultaneous implementation of treatment and restoration and environmental protection. They carry out treatment while mining. After the open-pit mining is completed, it is necessary to restore the damaged local ecological environment. The primary purpose of ecological restoration is to restore the functions of the damaged ecosystem, including functions such as soil restoration quality and water resources, so that the ecosystem can regain its self-regulating and restoring capabilities. Through ecological restoration, the stability and sustainability of the ecosystem can be enhanced, and the frequency and intensity of natural disasters can be reduced.

[0003] In the existing process of improving soil water retention, usually, soil with good water retention, such as forest soil and vegetable garden soil rich in humus, is transported to the mine and covered on the surface layer, and then a roller is used to compact the soil, reducing the pores between soil particles and increasing the soil density. This helps to enhance the bearing capacity of the soil and reduce problems caused by soil settlement in the later stage. At the same time, it can also make the soil more compact, reduce water seepage and loss, and improve water retention. However, when compacting the soil, the lighting degrees in different areas are different, resulting in different soil water contents in different areas. When rushing the construction period, it is not convenient to further fully dry the soil with a higher water content. When the roller compacts, the soil is prone to the "spring" phenomenon, that is, it seems to be compacted on the surface, but rebounds after loosening, unable to achieve the expected compaction effect. Moreover, too much water reduces the cohesion between soil particles, and the compacted soil structure is loose and lacks strength, greatly reducing the soil water retention. Also, the soil is muddy, making it difficult for the roller to travel and prone to the "spring" phenomenon, unable to be effectively compacted. To prevent the roller from sinking into the soil or having other failures, the traveling speed should be slowed down. However, the existing speed reduction is usually manually operated, but manual operation is not convenient for adjusting the corresponding traveling speed according to the actual water content. Therefore, we propose a device for improving soil water retention. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for improving soil water retention to solve the problems in the above background art that when the existing roller compacts, the soil is prone to the "spring" phenomenon, that is, unable to achieve the expected compaction effect, and too much water reduces the cohesion between soil particles, the compacted soil structure is loose and lacks strength, greatly reducing the soil water retention, and the speed reduction is usually manually operated, but manual operation is not convenient for adjusting the corresponding traveling speed according to the actual water content.

[0044] The following is a further introduction in combination with the specific working mode, as described in detail below: Specifically, when the soil water retention improvement device is working and the device is running, the mud scraping plate 8 can separate the soil on the vertical roller of the device, enabling the wet soil on the vertical roller to enter the collection box 10 through the mud scraping plate 8. The second pressure sensor 11 converts the received extrusion force into an electrical signal and transmits it to the control device 14. The control device 14 controls the opening of the electromagnetic three-way valve 37 valve, so that the oil tank 35 is connected to the first connecting pipe 38, and then the electric push rod 31 is started. The electric push rod 31 discharges the air inside the piston tube 33 into the oil tank 35 through the air outlet pipe 34. The air entering the oil tank 35 pushes the second piston 36. The second piston 36 pushes the hydraulic oil in the oil tank 35 into the hydraulic cylinder 39 through the first connecting pipe 38. One end of the hydraulic cylinder 39 moves outward and pushes the sealing plate 310 downward, opening one end of the dry soil box 311. The dry soil inside the dry soil box 311 is discharged outward through the discharge port and the dispersion plate 5.

[0045] The first pressure sensor 314 detects the weight of the dry soil inside the dry soil box 311. When the weight of the wet soil entering the collection box 10 is the same as the weight of the dry soil discharged from the dry soil box 311, the first pressure sensor 314 transmits an electrical signal to the control device 14. The control device 14 controls the conversion of the electromagnetic three-way valve 37 valve, making the first connecting pipe 38 communicate with the second connecting pipe 41. While the fixing spring 313 drives the sealing plate 310 to reset, the sealing plate 310 drives the hydraulic cylinder 39 to reset, causing the hydraulic oil inside the hydraulic cylinder 39 to be discharged into the first connecting pipe 38. Through the first connecting pipe 38 and the second connecting pipe 41, it enters the fixed pipe 42. The hydraulic oil entering the fixed pipe 42 pushes the moving rod 44 to move outward. The movement of the moving rod 44 drives the sliding piece of the sliding rheostat 46 to move, changing the resistance of the sliding rheostat 46, thereby changing the traveling speed of the device.

[0046] When the first pressure sensor 314 is interrupted from the second pressure sensor 11, the control device 14 controls the valve conversion of the electromagnetic three-way valve 37 to connect the oil tank 35 with the second connecting pipe 41. The compression spring 45 drives the moving rod 44 to reset, and the reset of the moving rod 44 drives the sliding plate of the sliding rheostat 46 to reset, so that the second pressure sensor 11 can perform cyclic interruption detection.
