[0026] Reference Figure 1-4 This utility model provides a soil heavy metal pollution treatment device, comprising:

[0027] The treatment unit 100 includes a base 101. Wheels 102 are mounted on the lower surface of the base 101. A conveyor 103 is fixedly connected to the middle of the upper surface of the base 101. A spray box 105 is fixedly connected to the upper surface of the base 101. A storage tank 106 is fixedly connected to the upper surface of the spray box 105. A spray pipe 107 is fixedly connected to the lower surface of the storage tank 106. A nozzle 108 is fixedly connected to the lower surface of the spray pipe 107. A soil loosening component 111 is mounted at one end of the base 101. The two ends of the conveyor 103 are inclined. A spreader 104 is fixedly connected to the other end of the base 101. The spreader 104 is located below the output end of the conveyor 103, and its interior is connected to the interior of the base 101. The soil loosening component 111 loosens the contaminated soil, breaks up soil clumps, and increases soil permeability and aeration, providing good physical conditions for subsequent treatment. The storage tank 106 contains specific chemical remediation agents such as chelating agents, acidic or alkaline solutions, etc. The remediation agents are evenly sprayed onto the loosened soil surface through the spray box 105, spray pipe 107 and nozzle 108. The remediation agents react chemically with heavy metals in the soil, changing the form of heavy metals, reducing their bioavailability or promoting their desorption from the soil. The spreader 104 is located below the output end of the conveyor 103 and is connected to the interior of the base 101. Its interior contains a container for storing soil conditioners. When the soil is transported to the spreader 104 through the conveyor 103, the spreader 104 evenly spreads specific soil conditioners such as lime and organic fertilizers on the soil, further improving the physical and chemical properties of the soil and promoting the restoration of soil structure.

[0028] The upper surface of the spray pipe 107 is fixedly connected to the inner top wall of the spray box 105. Multiple baffles 109 are fixedly connected to the inner top wall of the spray box 105, and the spray pipe 107 is positioned on the adjacent sides of the baffles 109. Multiple toothed blocks 110 are fixedly connected to the lower surface of the baffles 109, and these blocks are staggered, with their lower ends abutting the upper surface of the conveyor 103. When the soil is transported by the conveyor 103, the toothed blocks 110 further loosen and agitate the soil. This mechanical action enhances the penetration of the remediation agent, allowing it to penetrate deep into the soil and fully contact the heavy metal pollutants, promoting chemical reactions. The rational arrangement of the spray pipe 107 and the baffles 109 ensures uniform spraying of the remediation agent, avoiding differences in remediation effects due to uneven spraying and improving the overall efficiency of the remediation process.

[0029] Furthermore, the soil loosening component 111 includes a protective cover 111a, one end of which is fixedly connected to one end of the base 101. A cylinder 111b is fixedly connected inside the protective cover 111a, and a soil turner 111c is fixedly connected to the output end of the cylinder 111b. Slide rods 111d are fixedly connected to both sides of the upper surface of the soil turner 111c. The outer surface of the slide rods 111d is slidably connected to the inside of the protective cover 111a. The soil turner 111c is located at the other end of the conveyor 103, and the width of the conveyor 103 is greater than the width of the base 103. By controlling the extension and retraction of the cylinder 111b, the soil turner 111c is driven to move up and down, thereby loosening and turning the soil, breaking up the soil compaction layer, increasing soil porosity, and improving aeration and permeability. The slide rod 111d is slidably connected to the inner wall of the protective cover 111a to ensure the smooth vertical movement of the soil turner 111c, avoid deviation, improve the accuracy and efficiency of soil loosening operations, and replace manual soil loosening with mechanized operation, thereby improving work efficiency and reducing labor costs.

[0030] During use, the soil turner 111d is first activated, and its height is controlled by the cylinder 111b to facilitate soil loosening. The loosening component 111 loosens the contaminated soil, breaks up soil clumps, and increases soil permeability and aeration. Then, a portion of the soil is lifted by the conveyor 103 and sprayed evenly onto the loosened soil surface through the spray box 105, spray pipe 107, and nozzle 108. During the spraying process, the toothed block 110 divides and mixes the soil to improve the uniformity of mixing. The soil is then conveyed by the conveyor 103 to the spreader 104, where the spreader 104 evenly spreads a specific soil conditioner onto the soil to further improve the physical and chemical properties of the soil, promote the restoration of soil structure, and thus improve the remediation effect.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
