Detailed Embodiment

[0030] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Embodiment

[0031] The present invention discloses a soil remediation device for ecological restoration, as Figure 1 shown, which includes a counterweight bottom plate 1. The counterweight bottom plate 1 provides a good center of gravity, enhances the stability of the device on uneven terrain, reduces the risk of tipping, and ensures smooth operation during the remediation process; four driving wheels 2 are provided at the bottom of the counterweight bottom plate 1, and a handle 3 is fixedly installed on the upper surface of the counterweight bottom plate 1. The four driving wheels 2 at the bottom enable the device to move easily and adapt to different working environments; this flexibility is particularly important and can improve work efficiency in complex terrains; the design of the handle 3 enables users to conveniently push and pull the device, reducing the labor intensity of operation and improving the user's operation experience.

[0032] As Figure 1 and Figure 2 shown, a control box 4 is fixedly installed on the upper surface of the counterweight bottom plate 1. The control box 4 is provided with an opening vertically downward. A limiting plate 5 is arranged inside the control box 4, and a number of positioning holes 6 are arranged inside the limiting plate 5. The limiting plate 5 and the positioning holes 6 inside it provide stable support and accurate positioning for the drill rod 7, making it more accurate when rotating and drilling, and avoiding the possible reduction in efficiency and irregular construction caused by random deviation; the drill rod 7 is arranged in the positioning hole 6 of the limiting plate 5, and a driving component 10 for driving the drill rod 7 is arranged inside the limiting plate 5. A conical drill bit 8 is provided at the bottom of the drill rod 7. Through the power provided by the driving component 10, the drill rod 7 can rotate efficiently; through the rotation of the drill rod 7, the difficulty of drilling into the soil can be effectively reduced, and at the same time, the process of soil fragmentation can be accelerated, improving the remediation speed; due to its special conical shape, the conical drill bit 8 can effectively penetrate the ground surface, reduce the resistance of drilling into the soil, and reduce the disturbance to the surrounding soil during the drilling process; this design helps to form appropriate holes and avoid excessive disturbance, thereby protecting the soil structure; after the drill rod 7 successfully penetrates the ground surface, the remediation agent can smoothly enter the soil holes; in this way, the remediation agent can not only penetrate deeply, but also cover a wider area, effectively improving the physical and chemical properties of the soil.

[0033] As Figure 1 and Figure 2As shown, a spiral blade 9 is provided on the outer surface of the drill pipe 7. The spiral blade 9 can effectively cut the soil, increase the drilling efficiency, and reduce the working time. Moreover, it helps to discharge the loosened soil and rocks upward during the drilling process, keep the borehole clean, and prevent blockage. In addition, the design of the spiral blade 9 can improve the strength and stability of the drill pipe 7, making it not easy to bend or deform during operation. The spiral blade 9 is detachably connected to the drill pipe 7. If the spiral blade 9 is worn or damaged, it can be easily disassembled and replaced, reducing the maintenance cost and downtime of the equipment.

[0034] As Figure 3 shown, specifically, the drive assembly 10 includes a drive motor and a first gear 1001. The center point of the first gear 1001 is fixedly connected to the center point of the drill pipe 7. Every two adjacent first gears 1001 are meshed and connected through a second gear 1002. The output end of the drive motor is fixedly connected to the center point of the second gear 1002. By driving the drive motor, the second gear 1002 is rotated. By using the meshing connection between the second gear 1002 and the first gear 1001, the rotation of the drill pipe 7 is realized. The center point of the first gear 1001 is fixedly connected to the center point of the drill pipe 7 to ensure the rotation consistency of the drill pipe 7, avoid deviation and error, and enhance the drilling accuracy. Through first gears 1001 and second gears 1002 of different sizes, an effective transmission ratio adjustment can be achieved, improving the rotational speed and torque, so that the drill pipe 7 can quickly adapt to the requirements of different soil hardnesses.

[0035] As Figure 3 shown, a first electric telescopic rod 11 is fixedly installed inside the control box 4. The bottom output end of the first electric telescopic rod 11 is connected to the upper surface of the limiting plate 5. By means of the first electric telescopic rod 11, the limiting plate 5 is lifted and lowered inside the control box 4 to adapt to different soil properties and drilling requirements, facilitating the use of the equipment in various working environments.

[0036] As Figure 3 、 Figure 4 and Figure 5As shown in the figure, a through hole 12 is provided at the central position of the drill pipe 7, and a plurality of mud overflow ports 13 communicating with the through hole 12 are arranged on the outer surface of the drill pipe 7 and near the bottom position. If a soil layer containing groundwater is encountered and it is necessary to extract the groundwater in the soil layer to prevent the groundwater from diluting the repair agent. As the drill pipe 7 penetrates into the soil layer, the soil in the soil layer will be stirred and mixed with the groundwater to form mud. The mud enters the through hole 12 of the drill pipe 7 through the mud overflow port 13. Specifically, an installation top plate 14 is provided on the top of the control box 4. An installation hole 15 matching the number of drill pipes 7 is provided inside the installation top plate 14. A water suction pipe 16 is provided in the installation hole 15 of the installation top plate 14. One end of the water suction pipe 16 is connected to the input end of a water suction pump 17 arranged on the counterweight bottom plate 1, and the other end of the water suction pipe 16 penetrates through the installation top plate 14 and extends into the through hole 12. Through the water suction pump 17, the mud in the through hole 12 is pumped out to keep the working environment clean; by pumping water, the groundwater level can be better controlled to ensure the safety of the construction area; continuously pumping the mud can reduce the mixing of soil and groundwater and avoid affecting the drilling accuracy; by effectively pumping out the groundwater, it is prevented from diluting the repair agent to ensure that the repair effect is maximally maintained.

[0037] As Figure 5 As shown in the figure, a first centrifugal pump 18 and a batching barrel 19 for batching and mixing the repair agent are fixedly installed on the upper surface of the counterweight bottom plate 1. An agent outlet is provided at the bottom of the batching barrel 19. The agent outlet of the batching barrel 19 is communicated with the input end of the first centrifugal pump 18 through a first pipeline 20. The output end of the first centrifugal pump 18 is connected with a second pipeline 21. One end of the second pipeline 21 is connected to the first centrifugal pump 18, and the other end of the second pipeline 21 is communicated with the input end of a special-shaped channel inside the installation top plate 14. The output end of the special-shaped channel of the installation top plate 14 is connected with a plurality of branch pipes 22. The branch pipes 22 are located on the lower surface of the installation top plate 14 and penetrate through the through hole 12 of the drill pipe 7. When the first centrifugal pump 18 starts to operate, the mixed repair agent is extracted and flows to the output end of the second pipeline 21 under the action of the first centrifugal pump 18; the second pipeline 21 transports the repair agent to the special-shaped channel of the installation top plate 14 to ensure that the repair agent can smoothly flow into each part of the system; the output end of the special-shaped channel is connected with a plurality of branch pipes 22, and these branch pipes 22 penetrate through the through hole 12 of the drill pipe 7 to accurately transport the repair agent into the through hole 12; the design of the branch pipes 22 enables the repair agent to be transported at multiple points simultaneously to ensure uniform distribution of the material and improve the repair effect.

[0038] As Figure 6As shown, specifically, a number of branch pipes 22 are arranged at equal angles around the central axis of the water extraction pipe 16. The branch pipes 22 are evenly distributed around the central axis, which helps to evenly spray the repair agent in all directions, ensuring uniform coverage of the construction area. Moreover, the water outlets of the branch pipes 22 face vertically downward. This can make the repair agent flow more smoothly towards the target area by gravity, reducing the possible retention of the liquid during transportation. Also, it reduces the resistance of the fluid in the branch pipes 22, promotes the rapid outflow of the liquid, and improves the overall flow efficiency. The design of the vertically downward water outlet enables the repair agent to quickly flow out and cover the target area, reducing the construction time.

[0039] As Figure 7 shown, a second electric telescopic rod 23 is fixedly installed on the upper surface of the counterweight bottom plate 1. The top output end of the second electric telescopic rod 23 is connected to the bottom of the installation top plate 14. Through the second electric telescopic rod 23, the linear motion of the electric telescopic rod can be converted into the up and down movement of the installation top plate 14. Therefore, the relative height between the branch pipe 22 and the water extraction pipe 16 can be accurately adjusted, so as to extract mud at different depths and inject the repair agent at different depths.

[0040] As Figure 7 shown, a number of sealing rings 24 matching the top of the drill pipe 7 are provided on the lower surface of the installation top plate 14. The inner diameter of the sealing ring 24 is equal to the outer diameter of the top of the drill pipe 7. When the installation top plate 14 moves up and down through the second electric telescopic rod 23, the sealing ring 24 is designed to effectively contact the top of the drill pipe 7, thus forming an effective sealing structure. When the second electric telescopic rod 23 retracts and the installation top plate 14 moves downward, the sealing ring 24 will be stuck on the top of the drill pipe 7, making the inner circle of the sealing ring 24 fit tightly with the outer circle of the drill pipe 7. Such a design effectively prevents the leakage of mud and other fluids from the through hole 12 during the extraction process, improving the tightness of the operation. Due to the presence of the sealing ring 24, it can ensure that the mud in the through hole 12 is effectively locked during the extraction of mud, and the mud can be quickly extracted without being interfered by the external environment. At the same time, the good sealing performance also reduces the splashing and pollution of the mud during the extraction process, ensuring the cleanliness of the operation environment. Moreover, the sealing structure can withstand a certain pressure change, ensuring the stability of the internal pressure during the drilling process, preventing the backflow of mud or the escape of harmful substances, and enhancing the safety and reliability of the system.

[0041] As Figure 7As shown, a number of overflow holes 25 of different sizes are provided inside the spiral blade 9. The overflow holes 25 of different sizes can help evenly distribute the repair agent so that it can cover the area to be repaired, ensuring a more comprehensive and uniform repair effect. The overflow holes 25 are interconnected with the through holes 12. The repair agent overflows from the overflow holes 25 inside the spiral blade 9 through the through holes 12. By providing multiple overflow holes 25, it can effectively avoid the poor flow of the repair agent caused by the blockage of a certain hole, thus maintaining the continuity and effectiveness of the repair process.

[0042] Working principle: Before use, the user first puts the raw materials of the repair agent to be prepared through the feed port at the top of the batching barrel 19 into the inside of the batching barrel 19, and uses the stirring assembly inside the batching barrel 19 to obtain the prepared repair agent.

[0043] Then, through the handle 3 and the driving wheel 2, the soil repair device is moved to the position to be repaired. Then, the driving motor on the limiting plate 5 is started. The driving motor drives the first gear 1001, so that the drill rod 7 rotates inside the limiting plate 5. Under the meshing and linkage action of the second gear 1002, a number of drill rods 7 rotate simultaneously. Then, by using the first electric telescopic rod 11, the drill rod 7 moves towards the ground surface until the rotating conical drill bit 8 contacts the ground surface for forming a hole on the ground surface.

[0044] When the drill rod 7 penetrates to a certain depth, the second electric telescopic rod 23 is started so that the sealing ring 24 seals the top of the drill rod 7. Then, the power supply of the first centrifugal pump 18 is started, and the repair agent prepared in the batching barrel 19 is sequentially introduced into the inside of the through hole 12 of the drill rod 7 and overflows through the overflow holes 25 on the spiral blade 9, filling the hole to achieve multi-level repair of the soil.

[0045] Before injecting the repair agent, if there is a large amount of groundwater in the hole, in order to avoid the dilution of the repair agent by the groundwater, the water level sensor on the inner wall of the through hole 12 of the drill rod 7 detects the water level information. The water level sensor transmits the detected information to the controller on the counterweight bottom plate 1. The controller is used to control the switch of the first centrifugal pump 18. Through the first centrifugal pump 18 and with the help of the water suction pipe 16, the groundwater in the hole is pumped out. When the groundwater returns to the normal level, the power supply of the first centrifugal pump 18 is controlled and turned off by the controller.

[0046] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
