[0002] With the accelerating pace of industrialization, the unreasonable exploitation of mineral resources, emissions from smelting, atmospheric pollution deposition, and the long-term use of wastewater irrigation and sludge application have led to the accumulation of large amounts of harmful substances in the soil. Furthermore, the extensive use of chemical fertilizers and pesticides in agricultural production has further exacerbated the accumulation of heavy metals, organic pollutants, and other harmful components in the soil. These pollutants not only damage the soil's ecological structure and microbial system but may also enter the food chain through crops, posing a potential threat to human health. Therefore, how to efficiently and environmentally remediate and regenerate soil has become a crucial issue that urgently needs to be addressed.

[0028] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0030] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0031] like Figure 1-2 As shown in the figure, this utility model embodiment proposes a contaminated soil remediation device, including a fixed plate 1, two mounting seats 2 rotatably disposed on the fixed plate 1, and a telescopic member 4 disposed on the fixed plate 1; wherein, the two mounting seats 2 are respectively located on one side of the fixed plate 1 to form an included angle, and both mounting seats 2 are provided with spray pipes 3; the telescopic member 4 is connected to the two mounting seats 2 through a connector, and is used to synchronously move the two spray pipes 3 closer to each other or further away, so as to adjust the included angle of the two spray pipes 3.

[0032] In this embodiment of the invention, during use, the telescopic component 4 is manipulated to extend or retract according to the actual width requirements of the repair area. Since the telescopic component 4 is connected to the two mounting bases 2 via connectors, the movement of the telescopic component 4 will cause the two mounting bases 2 to rotate synchronously, thereby changing the included angle between the two spray pipes 3. That is, when the telescopic component 4 extends, the two spray pipes 3 gradually open outwards, increasing the included angle; when the telescopic component 4 retracts, the two spray pipes 3 move closer together, decreasing the included angle. Therefore, the distribution range of the spray pipes 3 can be controlled by extending and retracting the telescopic component 4, thereby adapting to working areas of different widths and improving work efficiency. The telescopic component 4 can be any one of an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder; no limitation is made in this embodiment.

[0033] Specifically, such as Figure 1-2 As shown in this embodiment of the utility model, the connecting member includes a slide 5 connected to the telescopic end of the telescopic member 4. Connecting rods 6 are rotatably provided on both sides of the top of the slide 5. The two connecting rods 6 are respectively connected to the two mounting seats 2. When the telescopic end of the telescopic member 4 moves, it drives the slide 5 connected to it to move synchronously. That is, when the slide 5 moves forward, the two connecting rods 6 synchronously push the two mounting seats 2 outward, and the included angle between the two spray pipes 3 increases accordingly. When the slide 5 moves backward, the connecting rods 6 pull the mounting seats 2 inward, and the two spray pipes 3 gradually approach each other, reducing the included angle. This achieves matching between the spraying area and the contaminated soil area, improving spraying efficiency and uniformity.

[0034] Secondly, the fixed plate 1 has a sliding groove 101, and the slide block 5 has a slider. The slider is slidably engaged in the sliding groove 101 to guide and limit the movement of the slide block 5. Through the cooperation of the slider and the sliding groove 101, not only can the linear movement of the slide block 5 on the fixed plate 1 be guided, but it can also effectively prevent the slide block 5 from shifting during the extension and retraction of the telescopic member 4, and avoid the telescopic end from bearing unnecessary radial force, thereby improving the stability and service life of the structure.

[0035] In this embodiment, the slider is a T-shaped block and the slide groove 101 is a T-shaped groove. The T-shaped structure has good limiting and anti-offset performance, which can ensure that the slide block 5 slides smoothly and reliably in the slide groove 101, avoiding jamming or shaking during the spray angle adjustment process, and further improving the adjustment accuracy and operational reliability.

[0036] Specifically, such as Figure 1-2As shown in this embodiment of the utility model, at least one clamp 7 is provided on each of the two mounting bases 2. The spray pipe 3 is located between the clamp 7 and the mounting base 2. The clamp 7 clamps and fixes the spray pipe 3, thereby achieving a stable installation of the spray pipe 3 on the mounting base 2, preventing shaking or displacement, and ensuring a stable spraying direction and uniform spraying effect. The clamp 7 can adopt a threaded fastening, quick-release buckle, or adjustable clamp 7 structure to adapt to spray pipes 3 of different diameters.

[0037] Secondly, to further improve the stability of the spray pipe 3, the mounting base 2 is provided with an arc-shaped groove, and the spray pipe 3 is snapped into the arc-shaped groove. When the spray pipe 3 is installed on the mounting base 2, the spray pipe 3 can be initially limited and fixed under the action of the arc-shaped groove, so as to facilitate the installation of the clamp 7 and prevent the spray pipe 3 from shifting. Moreover, in the process of fixing the spray pipe 3, the circular channel formed by the arc-shaped groove and the clamp 7 is more adapted to the shape of the spray pipe 3.

[0038] Based on the above solutions, such as Figure 1-2 As shown, in this embodiment of the utility model, it also includes a mounting frame 8 and a lead screw 9 rotatably mounted on the mounting frame 8. A driving block 10 is provided on the fixed plate 1. The driving block 10 is connected to the lead screw 9 in a transmission manner. Through this structure, the driving block 10 can move along the axial direction when the lead screw 9 rotates, thereby driving the fixed plate 1 to rise or fall in the vertical direction.

[0039] This device installs a support frame at the rear or bottom of mobile equipment (such as agricultural vehicles, self-propelled platforms, etc.). For example, the mounting frame 8 has several mounting holes 801 for fasteners (such as bolts, nuts, etc.) to pass through. Fasteners can be inserted into the mounting holes 801 and installed onto the mobile equipment. Then, the mobile equipment can be used to carry out the operation, thereby realizing continuous spraying of the contaminated soil area.

[0040] Specifically, when the device is not in operation, rotating the lead screw 9 causes it to rotate on the mounting bracket 8, which in turn moves the drive block 10 upward, causing the fixing plate 1 to rise accordingly. This raises the spray pipe 3 away from the road surface, effectively preventing scratches or wear caused by the device moving with vehicles. When it is time to resume operation, simply rotate the lead screw 9 in the opposite direction, causing the drive block 10 to slowly lower the fixing plate 1 until the spray pipe 3 is close to the work area and near the ground, thus resuming the spraying and repair operation.

[0041] Furthermore, the mounting frame 8 is provided with a limiting rod 11, and the fixing plate 1 is sleeved on the limiting rod 11. By setting the limiting rod 11 on the mounting frame 8 and sleeved on it, the up and down movement of the fixing plate 1 can be guided and limited, preventing it from deviating, shaking or tilting during the drive of the lead screw 9, thereby helping to improve the stability and parallelism of the fixing plate 1 during the movement process.

[0042] Secondly, in order to facilitate the rotation of the lead screw 9, the mounting frame 8 is provided with a handwheel 12. The lead screw 9 passes through the mounting frame 8 and is connected to the handwheel 12. By setting the handwheel 12, the operator can directly rotate the handwheel 12 to drive the lead screw 9 to rotate, thereby driving the drive block 10, which is threadedly connected to the lead screw 9, to move axially, so as to realize the lifting and lowering adjustment of the fixed plate 1.

[0043] Specifically, the mounting bracket 8 has a groove 802, and the handwheel 12 is located in the groove 802. By embedding the handwheel 12 in the groove 802 of the mounting bracket 8, the external dimensions of the overall structure are effectively reduced, and the handwheel 12 is prevented from being exposed, thus affecting the installation of the mounting bracket 8. At the same time, the overall compactness of the device is also improved.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions 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 solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
