Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soil remediation technology, and in particular relates to a soil remediation device. Background Technology
[0002] Soil remediation is the process of restoring contaminated soil to a state free from contamination. Soil remediation typically involves injecting agents and microorganisms into the contaminated soil. The microorganisms and agents are packaged in separate metal cylinders, which are then pressurized to allow the microorganisms and agents to flow out through outlet pipes, thus achieving the effect of soil injection.
[0003] Chinese patent application CN222551670U discloses a soil remediation device, including a vehicle body with wheels. The lower surface of the vehicle body's floor is sequentially equipped with a digging mechanism, a chemical injection mechanism, and a flattening mechanism. The digging mechanism is used to excavate the soil. The chemical injection mechanism includes an insertion mechanism, a liquid inlet mechanism, a drive motor, and a chemical tank. The drive motor provides driving force to the insertion and liquid inlet mechanisms. The insertion mechanism is used to insert into the soil, and the liquid inlet mechanism injects chemical solution after insertion. The chemical tank, located on the vehicle body, supplies chemical solution to the liquid inlet mechanism. The flattening mechanism flattens the excavated soil. This invention allows for adjustment of the injection depth according to different terrain conditions, enabling more precise soil remediation and improving remediation efficiency.
[0004] The aforementioned soil remediation device has a digging mechanism at the bottom of its vehicle body. This mechanism digs and loosens the soil, but it can only loosen the surface layer, failing to loosen the heavily polluted middle layer. Furthermore, it has an insertion mechanism that drives a liquid injection mechanism into the soil to inject the reagent. This results in the reagent being primarily distributed at the insertion point, requiring subsequent diffusion through natural outward and downward permeation. This method is slow and results in a large amount of reagent remaining within the insertion hole, with very little actually diffusing outward. Therefore, we provide a soil remediation device to address these problems. Utility Model Content

[0015] This utility model has the following beneficial effects:
[0016] This utility model features a base, a fixing plate, and a positioning column. The base is used not only for installing the air cylinder, but also has fixing plates at both ends.

The two ends of the positioning post 3 are respectively welded with a pedal 302 and a conical post 303. The upper side wall of the sliding insertion hole 201 is provided with a top groove 201a for engaging the pedal 302.
[0029] The operation process of this embodiment is as follows: When in use, step on the pedal 302 with your foot and step down hard to insert the positioning column 3 into the soil through the soil-breaking ability of the conical column 303. In this way, the other positioning column 3 can also be inserted into the soil, thus achieving the fixing effect of the base 1. Example 2
[0030] Please see Figure 4 Based on Example 1, an air cylinder 5, a material bucket 7, and a hydraulic rod 8 are also provided. The material bucket 7 can be used to provide gas and soil remediation agent to the air cylinder 5, and the hydraulic rod 8 can be used to deliver the agent and gas in the air cylinder 5 into the soil layer.
[0031] Specifically, a fixing groove 101 is provided on the base 1, and the base 1 is connected to the air cylinder 5 through the fixing groove 101. An installation groove 101a is also provided on the outer side of the fixing groove 101, and the installation groove 101a is threadedly connected to the fixing frame 4. The air cylinder 5 is snapped into the inside of the fixing frame 4. A piston rod 503 is also slidably inserted into the air cylinder 5. A material bucket 7 is connected to the lower middle outer wall of the air cylinder 5. The upper side wall of the air cylinder 5 is connected to the top of the piston rod 503 through a hydraulic rod 8. An air nozzle 6 is threadedly connected to the bottom of the air cylinder 5.
[0032] Furthermore, the air cylinder 5 is provided with a cylinder groove 501, and the two ends of the piston rod 503 are respectively fixed with a traction plate 505 and a piston body 504. The piston body 504 also cooperates with the inner wall of the cylinder groove 501. The traction plate 505 is used to connect with the top telescopic end of the hydraulic rod 8. The top side wall of the cylinder groove 501 of the air cylinder 5 is also inlaid with a sliding sleeve 503a for sliding cooperation with the piston rod 504.
