Description

Technical Field

[0001] This application relates to the technical field of contaminated soil remediation, and in particular to a remediation device for treating soil in the ecological environment. Background Technology

[0002] Soil remediation is a crucial environmental protection effort that aims to treat contaminated soil using a variety of methods, including physical, chemical, and biological approaches. It involves transferring, absorbing, degrading, and transforming pollutants in the soil to reduce their concentration to acceptable levels, or converting toxic and harmful substances into harmless ones, thereby restoring the soil's health and ecological functions. This process is of great significance for protecting the environment, maintaining ecological balance, and safeguarding human health. In soil remediation, the soil is typically broken up beforehand to facilitate subsequent remediation operations.

[0003] In related technologies, a soil remediation device includes a support frame, four casters fixed to the bottom of the support frame, and a spraying assembly mounted on the support frame. A vertically adjustable crushing assembly is also installed at the lower part of the support frame. The spraying assembly includes a chemical tank fixed to the support frame, a spray pipe connected to the chemical tank, and several nozzles mounted on the spray pipe. The crushing assembly includes a motor fixed to the bottom of the support frame, a crushing rod coaxially connected to the motor, and several crushing blades fixed to the outer periphery of the crushing rod. During soil remediation, the crushing assembly is first lowered, then the motor drives the crushing blades to crush the soil, and finally, the spraying assembly sprays the crushed soil with chemical solution.

[0004] During the remediation process, once the remediation solution is sprayed, it will continuously spray onto the ground until the solution in the tank is completely depleted. However, the efficiency of workers using the remediation equipment to break up the soil is not always consistent. Typically, the initial breaking speed is faster, while the later stages are relatively slower. This results in prolonged spraying time in areas with slower efficiency, causing a large amount of solution to fail to effectively act on the soil for remediation, leading to unnecessary waste of the solution and indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a soil remediation device for ecological environment treatment, which solves the problem in the above-mentioned related technologies that the spraying time of the liquid solution is long in areas with low soil breaking efficiency, resulting in unnecessary waste.

[0006] This application provides a remediation device for ecological environment soil treatment, which adopts the following technical solution: A soil remediation device for ecological environment treatment includes a support frame, several casters at the bottom of the support frame, and a liquid storage tank on the top surface of the support frame. A spray pipe communicating with the liquid storage tank is horizontally arranged inside the support frame, and several spray nozzles are provided on the spray pipe. A fixed shaft is horizontally arranged inside the support frame, and a drive assembly on the support frame drives the fixed shaft to rotate and move up and down around its own axis. Soil-breaking blades are fixed on the outer periphery of the fixed shaft. A sealing plate and two adjusting rods are provided inside the support frame, with the sealing plate located at the spray pipe. Below, the middle part of the adjusting rod is rotatably connected to the vertical inner wall of the support frame. One end of the two adjusting rods is fixedly connected to the sealing plate, and the other end is above the fixed shaft. An arc-shaped protrusion is fixed on the outer periphery of the fixed shaft. An elastic element that drives the sealing plate to rotate upward is provided inside the support frame. When the fixed shaft moves down to the soil breaking state and rotates, the sealing plate is in a blocking state that blocks the spray nozzle when it abuts against the adjusting rod on the outer periphery of the fixed shaft, and in a spraying state that opens the spray nozzle when it abuts against the adjusting rod on the outer side of the arc-shaped protrusion.

[0007] By adopting the above technical solution, when the fixed shaft moves down to the soil-breaking state and rotates, the outer circumference of the fixed shaft alternately abuts against the outer side of the arc-shaped protrusion, allowing the sealing plate to switch between sealing and spraying states. In this way, in the early stages where soil-breaking efficiency is high, normal spraying of the pesticide can be carried out; when entering the later stages where soil-breaking efficiency is low, the sealing plate can promptly seal the spray nozzles, reducing the spraying time and preventing a large amount of pesticide from being sprayed for an extended period in low-efficiency areas, thus avoiding unnecessary waste. This reduces usage costs and helps to achieve more precise soil remediation, protecting the ecological environment.

[0008] Optionally, a positioning block is fixed on the vertical inner wall of the support frame, located below the end of the adjusting rod near the sealing plate. The elastic element includes a return spring located between the adjusting rod and the positioning block, with both ends of the return spring fixedly connected to the sides of the adjusting rod and the positioning block that are close to each other.

[0009] By adopting the above technical solution, the return spring provides a stable elastic force to the sealing plate, ensuring that the sealing plate can reliably remain in its initial state when no external force is applied. When the rotation of the fixed shaft causes changes in the related structure, altering the state of the sealing plate, the return spring can use its own elasticity to quickly reset the adjusting rod and the sealing plate at the appropriate time. This ensures the accuracy and timeliness of the sealing plate's switching between sealing and spraying states, improving the stability and reliability of the equipment operation.

[0010] Optionally, the drive assembly includes connecting rods slidably mounted vertically on two opposing vertical surfaces of the support frame, and a drive component mounted on the support frame to drive the connecting rods to move up and down; the two ends of the fixed shaft are respectively rotatably connected to the lower ends of the two connecting rods, and a power component that drives the fixed shaft to rotate around its own axis is fixed on one of the two connecting rods.

[0011] By adopting the above technical solution, the connecting rod slides vertically along the support frame, and in conjunction with the drive component, it can precisely drive the fixed shaft to move up and down, allowing for flexible adjustment of the height of the breaking blades to meet the remediation needs of soils at different depths. Simultaneously, the power component, mounted on the connecting rod, drives the fixed shaft to rotate, enabling the breaking blades to perform rotary breaking operations. This method, which achieves vertical movement and rotation functions through the coordinated action of different components, results in a clear structure and simple operation.

[0012] Optionally, the outer side of the support frame is provided with a traction handle, and the traction handle is provided with a locking element. The lower part of the liquid storage tank is rotatably connected to the inner wall of the support frame. The liquid storage tank can be rotated downward to a storage state inside the support frame and rotated upward to an application state above the support frame. The locking element can lock and limit the liquid storage tank in both states.

[0013] By adopting the above technical solution, when the equipment is not in use, the storage tank can be rotated downwards to a stowed state, reducing the overall space occupied by the equipment and facilitating storage and transportation; when in use, it can be rotated upwards to the application state, ensuring normal storage and spraying functions. The locking mechanism on the towing handle reliably locks and limits the storage tank in both states, preventing it from rotating arbitrarily during movement or operation, ensuring the stability and safety of the equipment, effectively avoiding problems such as liquid leakage caused by tank shaking, and guaranteeing the smooth progress of soil remediation work.

[0014] Optionally, the support frame is provided with two fixed rods that can slide up and down along the horizontal direction. One end of each fixed rod is fixedly connected to the outer peripheral surface of the two connecting rods. The upper side of the fixed rod is provided with a fixing notch located below the liquid storage tank. When the liquid storage tank is in a vertically downward state, the lower part can be inserted into the fixing notch after the connecting rod moves up.

[0015] By adopting the above technical solution, when the connecting rod moves upward, the lower part of the liquid storage tank, which is in a vertically downward retracted state, can be inserted into a fixed notch, which can further stabilize and limit the liquid storage tank, preventing it from shaking or shifting during equipment movement or operation, thus enhancing the overall stability of the equipment, ensuring the safe operation of the equipment, and avoiding adverse conditions such as liquid leakage caused by instability of the liquid storage tank.

[0016] Optionally, the support frame has a push plate located below the fixed rod along the horizontal direction. The two opposite sides of the upper side of the push plate are fixedly connected to the bottom surface of the ends of the two fixed rods away from the connecting rod. The push plate is used to flatten the soil after it has been broken and sprayed with pesticide.

[0017] By adopting the above technical solution, after the soil is broken up and sprayed with pesticide, the pusher plate moves with the equipment to level the soil, making the remediated soil surface smooth. This facilitates subsequent ecological restoration work, such as vegetation planting, and improves the soil remediation effect. At the same time, leveling the soil allows the pesticide to be distributed more evenly in the soil, further improving the utilization rate of the pesticide and enhancing the quality of soil remediation.

[0018] Optionally, the lower end of the traction handle is rotatably connected to the vertical side of the support frame. When the traction handle is in use, it is in a vertically upward state. At this time, the upper part of the traction handle is fixed with two gripping parts away from the support frame in the horizontal direction and has two extension rods facing the support frame. The locking member includes an elastic telescopic rod fixed to the end of the extension rod away from the traction handle and vertically downward. When the liquid storage tank is in the vertically upward state, a first locking block is fixed on the side facing the traction handle. The top surface of the first locking block in this state has a first locking hole. The lower end of the elastic telescopic rod can be inserted into the first locking hole when the traction handle and the liquid storage tank are in the vertically upward state.

[0019] By adopting the above technical solution, when the liquid storage tank is in use, the lower end of the elastic telescopic rod can be inserted into the first locking hole to reliably lock the liquid storage tank, preventing it from shaking during operation and ensuring stable equipment operation. Moreover, the elastic telescopic rod utilizes its own elasticity to automatically extend and retract during operation to complete the locking and unlocking actions, requiring no complicated operation and making it convenient to use.

[0020] Optionally, when the liquid storage tank is in a vertically downward state, a second locking block is fixed on the side facing the traction handle. The top surface of the second locking block in this state has a second locking hole, and the lower end of the elastic telescopic rod can be inserted into the second locking hole when the traction handle is in a vertically upward state.

[0021] By adopting the above technical solution, when the traction handle is in the vertical upward position, the lower end of the elastic telescopic rod can be inserted into the second locking hole to lock the liquid storage tank in the stored state. This design further enhances the stability of the liquid storage tank in the non-use state, preventing the tank from colliding with the support frame due to shaking during equipment movement or storage, thus avoiding equipment damage or liquid leakage.

[0022] Optionally, the support frame is provided with an intermediate rod on the outside for connecting the two extension rods.

[0023] By adopting the above technical solution, the middle rod connects the two extension rods into a whole, enhancing the stability and robustness of the entire traction handle structure. This allows the extension rods to work together better under stress, reducing the risk of structural damage caused by uneven force on one side. Simultaneously, it improves the accuracy and reliability of the locking mechanism (elastic telescopic rod), ensuring that the elastic telescopic rod can be stably inserted into the locking hole to achieve locking.

[0024] Optionally, the end of the extension rod facing the support frame is rotatably connected to the support frame, the rotation surface of the extension rod is parallel to the vertical plane, and the extension rod can be rotated, adjusted, and fixed; when the handle is rotated downward to a horizontal state, the lower end face of the grip is flush with the bottom surface of the moving wheel, and the extension rod can rotate towards the support frame to a horizontal state at this time, and the bottom surface of the elastic telescopic rod is flush with the bottom surface of the moving wheel at this time.

[0025] By adopting the above technical solution, the traction handle can be simultaneously adjusted to a suitable position when rotated to a horizontal state, allowing the intermediate rod, traction handle, and other components to form a "step." This design provides workers with a convenient platform for maintenance and cleaning operations, eliminating the need to carry additional ladders or other tools, thus saving time and labor costs. Furthermore, the structure can be folded up when not in use, without affecting the normal movement and operation of the equipment. This ensures the integrity of the equipment's functions while enhancing its flexibility and convenience, effectively improving the efficiency and safety of soil remediation work.

[0026] In summary, this application includes the following beneficial technical effects: As the fixed shaft moves down to the breaking-through state and rotates, the outer circumference of the fixed shaft alternately abuts against the adjusting rod with the outer side of the arc-shaped protrusion, switching the sealing plate between the sealing and spraying states. In this way, in the early stages when breaking-through efficiency is high, normal spraying of the pesticide can proceed; when entering the later stages where breaking-through efficiency is low, the sealing plate can promptly seal the spray nozzles, reducing spraying time and preventing unnecessary waste caused by prolonged spraying of pesticides in low-efficiency areas that fail to effectively act on soil remediation.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] Example: Reference Figure 1 and Figure 2 A soil remediation device for ecological environment treatment includes a support frame 1, four movable wheels 11 at the bottom of the support frame 1, a spraying component 2 and a soil breaking component 3 inside the support frame 1, and a drive component 4 installed on the outside of the support frame 1 to drive the soil breaking component 3 to operate and move up and down. When the support frame 1 is used, the drive component 4 first drives the soil breaking component 3 to move down and operate, breaking the soil that needs to be repaired. Then, the spraying component 2 sprays the repair liquid onto the broken soil, thereby completing the soil repair.

[0031] Reference Figure 2 and Figure 3The spraying assembly 2 includes a liquid storage tank 21 installed on the top surface of the support frame 1 and a spraying pipe 22 installed horizontally inside the support frame 1. The spraying pipe 22 is connected to the bottom of the liquid storage tank 21 through a hose 23. The spraying pipe 22 has several spray nozzles, and a manual shut-off valve (not shown in the figure) is installed on the hose 23.

[0032] Reference Figure 4 and Figure 5 The drive assembly 4 includes a connecting rod 41 that slides vertically on two opposite vertical surfaces of the support frame 1, and a drive component 42 mounted on the support frame 1 to drive the connecting rod 41 to move up and down. The drive component 42 is specifically a vertically mounted drive electric cylinder 421, which is a conventional structure and will not be described in detail here. The soil-breaking component 3 includes a fixed shaft 31 that is rotatably connected to the lower ends of two connecting rods 41 at both ends, and several soil-breaking blades 32 fixed on the outer periphery of the fixed shaft 31. One of the two connecting rods 41 is fixed with a power component 33 that drives the fixed shaft 31 to rotate around its own axis. The power component 33 is a conventional servo motor, which will not be described in detail here.

[0033] Reference Figure 4 , Figure 5 and Figure 6 The support frame 1 is provided with an adjustment component 5, which includes a sealing plate 51 and two adjustment rods 52. The sealing plate 51 is located below the spray pipe 22. The middle part of the adjustment rods 52 is rotatably connected to the vertical inner wall of the support frame 1. One end of the two adjustment rods 52 is fixedly connected to the sealing plate 51, and the other end is located above the fixed shaft 31. An arc-shaped protrusion 311 is integrally formed on the outer periphery of the fixed shaft 31. A positioning block 12 is fixedly installed on the vertical inner wall of the support frame 1, located below the end of the adjusting rod 52 near the sealing plate 51. The support frame 1 is provided with an elastic element 53 that drives the sealing plate 51 to rotate upward. The elastic element 53 includes a return spring 531 located between the adjusting rod 52 and the positioning block 12. The two ends of the return spring 531 are fixedly connected to the sides of the adjusting rod 52 and the positioning block 12 that are close to each other.

[0034] When the fixed shaft 31 moves down to the soil breaking state and the outer circumference of the fixed shaft 31 abuts against the adjusting rod 52, the elastic element 53 squeezes the adjusting rod 52, causing the sealing plate 51 to move up and block the spray nozzle. At this time, the sealing plate 51 is in the blocking state. When the fixed shaft 31 moves down to the soil breaking state and the outer side of the arc-shaped protrusion 311 abuts against the adjusting rod 52, the adjusting rod 52 squeezes the elastic element 53, causing the sealing plate 51 to move down and open the spray nozzle. At this time, the sealing plate 51 is in the spraying state.

[0035] Reference Figure 7 and Figure 8The outer side of the support frame 1 is provided with a traction handle 13, and the traction handle 13 is provided with a locking member 6. The lower part of the liquid storage tank 21 is rotatably connected to the inner wall of the support frame 1. The liquid storage tank 21 can rotate downward to the storage state inside the support frame 1 and rotate upward to the application state above the support frame 1. The locking member 6 can lock and limit the two states of the liquid storage tank 21.

[0036] Reference Figure 7 and Figure 8 The lower end of the traction handle 13 is rotatably connected to the vertical side of the support frame 1. When the traction handle 13 is in use, it is in a vertically upward state. At this time, the upper part of the traction handle 13 is fixed with two grip parts 131 away from the support frame 1 in the horizontal direction and has two extension rods 132 facing the support frame 1. The outside of the support frame 1 is provided with an intermediate rod 14 for connecting the two extension rods 132. The locking element 6 includes a resilient telescopic rod 61 fixed to the end of the extension rod 132 away from the traction handle 13 and vertically downward. The resilient telescopic rod 61 is a conventional telescopic rod with an internal spring, which provides the resilient force to keep the resilient telescopic rod 61 in an extended state. When the liquid storage tank 21 is in a vertically upward position, a first locking block 24 is fixed on the side facing the traction handle 13. The first locking block 24 has a first locking hole on its top surface in this position. When the traction handle 13 and the liquid storage tank 21 are in a vertically upward position, the lower end of the elastic telescopic rod 61 can be inserted into the first locking hole to lock the liquid storage tank 21 in this position.

[0037] Reference Figure 8 and Figure 9 When the liquid storage tank 21 is in a vertically downward state, a second locking block 25 is fixed on the side facing the traction handle 13, wherein a second locking hole is opened on the top surface of the second locking block 25 in this state; when the traction handle 13 is in a vertically upward state, the lower end of the elastic telescopic rod 61 can be inserted into the second locking hole.

[0038] Reference Figure 8 , Figure 9 and Figure 10 The support frame 1 has two fixed rods 15 that can slide up and down along the horizontal direction. One end of the two fixed rods 15 is fixedly connected to the outer peripheral surface of the two connecting rods 41 respectively. The upper side of the fixed rods 15 has a fixing notch 151 located below the liquid storage tank 21. When the liquid storage tank 21 is in a vertically downward position and the connecting rod 41 moves upward (the soil breaking component 3 stops breaking the soil), the lower edge of the liquid storage tank 21 can be inserted into the fixed notch 151, which improves the installation stability of the liquid storage tank 21 in this state; at this time, most of the liquid storage tank 21 is inside the support frame 1, which can improve the space utilization rate during long-distance transportation.

[0039] Reference Figure 9 and Figure 10 The support frame 1 has a push plate 16 located below the fixed rod 15 along the horizontal direction. The two opposite sides of the upper side of the push plate 16 are fixedly connected to the bottom surface of the ends of the two fixed rods 15 away from the connecting rod 41. When the soil breaking component 3 moves down and operates, after the agent is sprayed on the broken soil, the lower edge of the push plate 16 can flatten the broken and sprayed soil. (In hot weather) this can reduce the evaporation of the agent in the soil and improve the soil remediation effect.

[0040] Reference Figure 11 The end of the extension rod 132 facing the support frame 1 is rotatably connected to the support frame 1 by a wing bolt 17, wherein the rotation surface of the extension rod 132 is parallel to the vertical plane; the operator can manually tighten or loosen the wing bolt 17 to rotate and fix the extension rod 132. When the handle is turned downwards to a horizontal position, the lower end face of the grip 131 is flush with the bottom surface of the moving wheel 11, and the operator can rotate the extension rod 132 towards the support frame 1 to a horizontal position and fix it. At this time, the bottom surface of the elastic telescopic rod 61 is flush with the bottom surface of the moving wheel 11. The intermediate rod 14, traction handle 13, grip part 131 and elastic telescopic rod 61 in the above state together form a "step". When inspecting or cleaning the upper side of the repair equipment, the staff can directly step on the "step", which is more convenient and does not require other stepping materials.

[0041] The implementation principle of this application embodiment is as follows: In soil remediation applications, the connecting rod 41 is first moved downward by the drive cylinder 421, causing the fixed shaft 31 and the soil-breaking blade 32 to move to the soil-breaking state. Simultaneously, the servo motor drives the fixed shaft 31 to rotate, breaking up the soil. During this process, when the outer circumference of the fixed shaft 31 abuts against the adjusting rod 52, the elastic element 53 causes the sealing plate 51 to seal the spray nozzle; when the arc-shaped protrusion 311 abuts against the adjusting rod 52, the adjusting rod 52 squeezes the elastic element 53, causing the sealing plate 51 to move downward and open the spray nozzle, allowing the remediation liquid to spray onto the broken soil. When the soil-breaking component 3 operates, the push plate 16 flattens the broken and sprayed soil, reducing liquid evaporation and improving the remediation effect.

[0042] When the liquid storage tank 21 is in use (vertically upward), the elastic telescopic rod 61 is inserted into the first locking hole to lock the liquid storage tank 21. When the liquid storage tank 21 needs to be stored (vertically downward), the traction handle 13 is rotated to insert the elastic telescopic rod 61 into the second locking hole for locking. At this time, the drive assembly 4 drives the connecting rod 41 to move upward, and the lower edge of the liquid storage tank 21 is inserted into the fixing notch 151 of the fixing rod 15, improving installation stability. Moreover, most of the liquid storage tank is located within the support frame 1, improving space utilization.

[0043] When the traction handle 13 is rotated downwards to a horizontal position, the lower end face of the grip part 131 is flush with the bottom surface of the moving wheel 11. The extension rod 132 is rotated to a horizontal position and fixed in the direction close to the support frame 1. The bottom surface of the elastic telescopic rod 61 is also flush with the bottom surface of the moving wheel 11. At this time, the middle rod 14, the traction handle 13, the grip part 131 and the elastic telescopic rod 61 form a "step" to facilitate workers to step on and inspect or clean the upper side of the repair equipment.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
