Description

Technical Field

[0001] This invention belongs to the field of soil remediation technology, specifically relating to a device for improving and remediating ecological soil. Background Technology

[0002] Hilly areas are widely distributed in my country and serve as important agricultural production zones and ecological barriers. However, due to the large topographic relief and severe soil erosion, the soils in hilly areas generally exhibit uneven vertical distribution, significant differences in the thickness of the effective soil layer, and strong spatial variability in nutrients and pollutants. This unevenness poses great challenges to soil remediation work: if a uniform tillage depth and remediation solution spraying volume are adopted, it will inevitably lead to excessive loss of remediation solution in shallow soil areas and insufficient and ineffective remediation solution in deep soil areas, which not only wastes resources but may also cause secondary pollution.

[0003] First, the vertical structure of hilly soils is extremely unstable. In areas with gentle slopes or at the foot of slopes, long-term sedimentation results in deep soil layers, and pollutants migrate to these deeper layers. However, at the top of slopes or near erosion gullies, the soil is shallow, and pollutants are mainly concentrated on the surface. Most existing soil remediation equipment is designed for plains areas and uses a fixed deep tillage depth and constant spraying rate, which prevents it from reaching residual pollutants in the deeper soil layers. In areas with shallow soil, it also stirs up the parent material or gravel at the bottom layer. At the same time, a large amount of remediation solution cannot be absorbed by the limited soil and is lost, resulting in a waste of resources.

[0004] Secondly, the in-situ soil remediation process typically includes: loosening the soil, spraying the remediation solution, and covering with mulch to maintain humidity and temperature, promote microbial activity, and prevent the remediation solution from evaporating. However, current operational models often employ a step-by-step approach: first, a rotary tiller is used to turn the soil; then, a sprayer is used to spray the remediation solution; and finally, mulch is applied mechanically. This remediation method requires equipment relocation and repositioning between each step, and rainy weather can delay the mulching process, leading to evaporation or leaching of the remediation solution and impacting remediation efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a device for improving and remediating ecological soil, which can integrate soil turning, spraying and mulching during soil remediation, and can also perform soil remediation operations at different depths in hilly terrain, and can automatically adjust the amount of remediation liquid sprayed according to the depth of soil remediation.

The water pipe at the inlet is connected to the water tank, while the water pipe at the outlet runs through the main body and is connected to a spray plate. The spray plate is fixedly connected to the middle of the lower part of the main body.

[0011] In a preferred embodiment, a mounting shell is fixedly connected to the upper front side of the main body. The front and rear sides of the inner cavity of the mounting shell are provided with through grooves, and mounting brackets are slidably connected in the through grooves. A conical wheel is rotatably connected to the middle of the mounting bracket. A drive wheel is fixedly connected to the outer ring of the middle section of the rotating shaft. A belt is tumbledly connected to the inner ring of the drive wheel. The other end of the belt passes through the mounting shell and is tumbledly connected to the middle position of the two sets of conical wheels.

[0012] In a preferred embodiment, two sets of conical wheels are symmetrically arranged with their tips facing each other.

The front of the transmission rod passes through the mounting shell and is rotatably connected to the top surface of the main body, while the rear end of the transmission rod passes through the mounting shell and is fixedly connected to the drive unit of the piston pump.

[0013] In a preferred embodiment, a first spring is fixedly connected to the middle of the mounting bracket on the side away from the belt, and the other end of the first spring is fixedly connected to the middle of the inner cavity of the mounting shell.

[0015] In a preferred embodiment, a pull rope is fixedly connected to the middle left side of the push plate, and the left end of the pull rope passes through the mounting shell and is fixedly connected to the middle upper part of the lifting frame.

[0016] The technical effects achieved by this invention are as follows: The main body, covering unit, and water spraying unit of this invention enable integrated soil turning, spraying, and covering during soil remediation, improving the portability and efficiency of soil remediation. In use, the device is moved to the soil to be remediated. The lifting frame then lowers, causing the turning roller to contact the soil and perform turning operations. During turning, a piston pump operates, spraying the remediation solution onto the turned soil through a water spray plate. Simultaneously, a rotating shaft drives a winding roller to rotate, covering the sprayed soil surface with a film. After covering, as the device moves, a scraper re-adheres the turned soil onto the film for fixation, completing the soil remediation process. The drive and adjustment units of this invention enable soil remediation operations at different depths in hilly terrain, and automatically adjust the amount of remediation liquid sprayed according to the soil remediation depth to avoid resource waste or insufficient remediation. The lifting frame is adjusted to different heights according to the soil depth to prevent the soil turning roller from turning the soil too deeply or too insufficiently. When the lifting frame descends, it drives the push plate to move via a pull rope. The push plate, through an L-shaped plate, pushes the front and rear mounting frames and conical wheels away from each other. Because the conical wheels are moving away, the belt will be closer to the center of the conical wheels, creating a larger diameter difference between the drive wheel and the conical wheels, thereby increasing the rotational speed of the conical wheels. At this time, the rotating shaft rotates, driving the drive wheel and belt to rotate with the conical wheels. The conical wheels then drive the transmission rod to rotate, causing the piston pump to run at high speed, spraying the remediation liquid onto the turned-up soil through a spray plate. The film coating part of the present invention allows for easy disassembly and assembly of the take-up roller, facilitating maintenance. When the film inside the take-up roller is used up, the bracket can be opened directly, the take-up roller can be pulled away from the rotating shaft, and a new take-up roller can be replaced to complete the replacement of the take-up roller.

The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0023] Please see the appendix Figures 1 to 4 , Figures 6 to 9 , Figures 13 to 15 As shown, this embodiment provides a device for improving and remediating ecological soil, comprising: The main body 10 has a scraper 12 connected to its right side and a lifting frame 15 slidably connected to its left side. A soil turning roller 16 is installed at the lower end of the lifting frame 15. The film coating section 20 includes a support 21, which is installed above the main body 10. A rotating shaft 23 is connected inside the support 21, and a take-up roller 24 is connected to the rotating shaft 23. Sprinkler unit 30, which includes a piston pump 32 and a spray plate 34 connected to the piston pump 32; The drive unit 40 includes a mounting housing 41, a mounting bracket 42 slidably connected inside the mounting housing 41, a conical wheel 43 connected inside the mounting bracket 42, a drive wheel 44 connected to the outer ring of the rotating shaft 23, a belt 45 rollingly connected inside the drive wheel 44 and the conical wheel 43, a transmission rod 47 slidably connected inside the conical wheel 43, and the transmission rod 47 is connected to the piston pump 32. Adjustment part 50 includes an L-shaped plate 52, which is fixedly connected to the outside of the mounting frame 42. A push plate 54 is slidably connected inside the mounting shell 41. The push plate 54 is in contact with the inner wall of the L-shaped plate 52. A pull rope 58 is connected to the left end of the push plate 54 and is connected to the lifting frame 15. When the lifting frame 15 is displaced, the pull rope 58 drives the push plate 54 to move, and the push plate 54 drives the L-shaped plate 52 and the conical wheel 43 to move back and forth, causing the belt 45 to move closer to or further away from the center of the conical wheel 43. The conical wheel 43 drives the piston pump 32 through the transmission rod 47.

[0024] It should be noted that, in order to ensure the stable operation and use of the device, corresponding energy storage components and electrical control components should be installed inside the device and electrically connected through cables or other means, so as to ensure that the various electrical components inside the device can operate stably according to the predetermined program.

[0025] In this embodiment, the device is moved to the soil to be repaired, and then the lifting frame 15 is lowered to drive the turning roller 16 to contact the soil and perform turning operations. At the same time, the lifting frame 15 is adjusted to different heights according to the soil depth to avoid the turning roller 16 turning the soil too deeply or too little. When the lifting frame 15 is lowered, it will drive the push plate 54 to move through the pull rope 58. The push plate 54 will push the front and rear mounting frames 42 and the conical wheel 43 away from each other through the L-shaped plate 52. Since the conical wheels 43 are away from each other, the belt 45 will be close to the center of the conical wheel 43, so that there is a larger diameter difference between the drive wheel 44 and the conical wheel 43, thereby increasing the rotational speed of the conical wheel 43. At this time, the rotating shaft 23 will rotate, driving the drive wheel 44 and belt 45 to rotate with the conical wheel 43. The conical wheel 43 will then drive the transmission rod 47 to rotate, driving the piston pump 32 to operate and spray the remediation fluid onto the upturned soil through the spray plate 34. As the rotating shaft 23 rotates, it will also drive the take-up roller 24 to rotate, covering the soil surface sprayed with the remediation fluid with a film. After the film is covered, as the device moves, the scraper 12 will re-adhere the upturned soil back onto the film for fixation, completing the soil remediation operation.

[0026] Secondly, please refer to again Figures 1 to 3 A handle 11 is fixedly connected to the right side of the top surface of the main body 10. A scraper 12 is rotatably connected to the middle right side of the main body 10 via a rotating shaft. An electric push rod 13 is rotatably connected to the lower middle part of the handle 11 via a rotating shaft. The lower end of the electric push rod 13 is rotatably connected to the middle upper part of the scraper 12 via a rotating shaft. Two sets of guide rails 14 are fixedly installed on the left side of the main body 10. A lifting frame 15 is slidably connected inside the guide rails 14. A soil turning roller 16 is rotatably connected to the lower middle part of the lifting frame 15 through a ball bearing. A drive motor 17 is fixedly installed at the upper middle part of the lifting frame 15. The drive motor 17 is connected to the rotating shaft of the soil turning roller 16. A hydraulic rod 18 is fixedly installed on the upper left side of the main body 10. The output end of the hydraulic rod 18 is fixedly connected to the upper middle part of the lifting frame 15.

[0027] It should be noted that the handle 11 should be equipped with a control panel for controlling the operation of the device (not shown in the figure, and this is a common technical structure in the prior art, which will not be described in detail here), so as to facilitate the operator to control the operation of the device. The upper end of the guide rail 14 is provided with a through groove, and the lifting frame 15 can extend out of the through groove to facilitate subsequent maintenance operations; The drive unit 17 should drive the turning roller 16 to rotate via a chain or pulley (not shown in the figure, and this is a common technical structure in the prior art, so it will not be described in detail here), and a protective shell (such as...) should be provided on the rear side of the inner ring of the lifting frame 15. Figure 3 (as shown), and is located on the left side of the drive motor 17 and the turning roller 16. The drive structure connected to the drive motor 17 is set inside the protective shell; The hydraulic rod 18 is installed in the same direction as the sliding direction of the guide rail 14, so that the hydraulic rod 18 can drive the lifting frame 15 to slide within the guide rail 14.

[0028] In this embodiment, when in use, the hydraulic rod 18 pushes the lifting frame 15 to slide downward in the guide rail 14, causing the turning roller 16 to contact the soil. Then, the drive motor 17 drives the turning roller 16 to rotate, so that soil at different depths can be turned over. When it is necessary to adjust the scraping angle of the scraper 12, the extension and retraction of the electric actuator 13 can be used to drive the scraper 12 to rotate around the connecting shaft between it and the main body 10, thereby adapting to different soil covering requirements.

[0029] Secondly, please refer to again Figures 4 to 6 A through groove is provided in the middle of the upper end of the main body 10, and brackets 21 are fixedly installed on both the front and rear sides of the through groove. A motor 22 is fixedly installed in the middle of the upper end of the main body 10. A rotating shaft 23 is fixedly connected to the output shaft of the motor 22. The outer ring of the middle section of the rotating shaft 23 is rotatably connected to the middle of the bracket 21. A take-up roller 24 is movably inserted into the rear end of the rotating shaft 23. The take-up roller 24 is rotatably connected to the middle of the rear bracket 21. A film 25 is provided in the inner ring of the take-up roller 24. The lower end of the film 25 passes through the through groove in the middle of the main body 10 and contacts the ground surface. A guide roller 26 is rotatably connected to the middle of the lower end of the main body 10 through a ball bearing. The outer ring of the middle section of the film 25 is rotatably connected to the outer ring of the guide roller 26.

[0030] It should be noted that the bracket 21 is a detachable structure, and semi-circular gears are provided on both the upper and lower sides inside to facilitate the replacement of the winding roller 24. A square abutment block is provided at the part of the rotating shaft 23 that contacts the winding roller 24 in order to drive the winding roller 24 to rotate; Two sets of guide rollers 26 are provided, and the film 25 is rolled between the two sets of guide rollers 26 to ensure stability.

[0031] In this embodiment, the operation of the motor 22 drives the rotating shaft 23 to rotate, which in turn drives the take-up roller 24 to rotate, so that it continuously releases the film 25. Under the guidance of the guide roller 26, the film 25 adheres to the soil surface after the remediation liquid has been sprayed, thereby completing the continuous film covering operation.

[0032] Secondly, please refer to again Figures 6 to 7 A water tank 31 is fixedly connected to the upper rear side of the main body 10. A piston pump 32 is fixedly installed in the middle of the upper part of the main body 10. The inlet and outlet of the piston pump 32 are both connected to water pipes 33. The water pipe 33 at the inlet is connected to the water tank 31, while the water pipe 33 at the outlet passes through the main body 10 and is connected to a spray plate 34. The spray plate 34 is fixedly connected to the middle of the lower part of the main body 10.

[0033] It should be noted that an inlet cover is provided on the upper left side of the water tank 31, and multiple sets of outlets are provided at the lower end of the spray plate 34 to facilitate spraying the repair liquid in the water tank 31 onto the upturned soil. The piston pump 32 is not equipped with a drive unit and is driven by the transmission rod 47.

[0034] In this embodiment, when the transmission rod 47 is driven to rotate, it drives the piston pump 32 to perform reciprocating suction and discharge operations, transporting the repair liquid stored in the water tank 31 to the spray plate 34 through the water pipe 33, and finally spraying it evenly from multiple outlets of the spray plate 34 into the interior of the turned soil, thus completing the application of the repair liquid.

[0035] Please refer to it again. Figures 7 to 12 The upper front side of the main body 10 is fixedly connected to the mounting shell 41. The front and rear sides of the inner cavity of the mounting shell 41 are provided with through grooves, and the mounting brackets 42 are slidably connected in the through grooves. The middle part of the mounting brackets 42 is rotatably connected to the conical wheel 43 through ball bearings. The outer ring of the middle section of the rotating shaft 23 is fixedly connected to the drive wheel 44. The inner ring of the drive wheel 44 is slidably connected to the belt 45. The other end of the belt 45 passes through the mounting shell 41 and is slidably connected in the middle of the two sets of conical wheels 43. The right side of the inner cavity of the mounting shell 41 is fixedly connected to the tension wheel 46. The outer ring of the middle section of the belt 45 is fixedly connected to the inner ring of the tension wheel 46. Two sets of conical wheels 43 are symmetrically arranged with their tips facing each other. A through groove is opened in the middle of each set of conical wheels 43. A transmission rod 47 is slidably connected in the through groove. The front of the transmission rod 47 passes through the mounting shell 41 and is rotatably connected to the top surface of the main body 10 through a ball bearing. The rear end of the transmission rod 47 passes through the mounting shell 41 and is fixedly connected to the drive unit of the piston pump 32.

[0036] It should be noted that the belt 45 is a rubber belt with a tapered cross-section, and the inclination angle of the two inclined sides is adapted to the inclination angle of the tapered pulley 43. This is intended to allow the two sets of tapered pulleys 43 to move away from or closer to each other, thereby moving the belt 45 away from or closer to the center of the tapered pulley 43. In turn, by changing the position of the belt 45, the rotational speed of the two sets of tapered pulleys 43 can be adjusted, thereby adjusting the rotational speed of the transmission rod 47 and the piston pump 32. Slide rods are provided on both the left and right sides of the mounting bracket 42, and the slide rods are slidably connected to the middle of the mounting shell 41, which is intended to limit the movement of the mounting bracket 42. A limit ring is provided at the contact position between the conical wheel 43 and the mounting bracket 42, so that the conical wheel 43 can only rotate within the mounting bracket 42 and cannot detach from the mounting bracket 42; When the two sets of conical wheels 43 are in the most closely fitted state, their outer ends will also extend and slide to connect with the middle of the mounting shell 41, thereby ensuring the stability of the position adjustment of the conical wheels 43. The through grooves in the middle of both sets of conical wheels 43 are hexagonal structures, and the outer ring of the middle section of the transmission rod 47 is also set as a hexagonal structure, so that the conical wheels 43 can slide on the outer ring of the transmission rod 47 and drive the transmission rod 47 to rotate. The right end of the mounting housing 41 has two sets of through grooves, and the height of the through grooves is much greater than the thickness of the belt 45. This ensures that the belt 45 will not scratch the mounting housing 41 after the belt 45 is adjusted, thus avoiding affecting the service life of the belt 45. The tension pulley 46 has an internal elastic structure, which allows it to be pushed or tightened by elastic force to keep the belt 45 in a taut state and avoid affecting the normal rolling of the belt 45. To ensure that the conical pulley 43 can smoothly drive the belt 45 away from or near the center of the conical pulley 43, the speed of the drive pulley 44 and the belt 45 should be reduced accordingly during adjustment to avoid excessive clamping force, which would affect the adjustment of the speed.

[0037] In this embodiment, when the rotating shaft 23 rotates, it drives the drive wheel 44 to rotate together. The drive wheel 44 drives two sets of conical wheels 43 to rotate synchronously through the belt 45. The conical wheels 43 then drive the transmission rod 47 to rotate, thereby completing the power transmission and providing the driving force required for the operation of the piston pump 32.

[0038] Please refer to it again. Figures 7 to 11 , Figures 13 to 15 A first spring 51 is fixedly connected to the middle of the side of the mounting bracket 42 away from the belt 45. The other end of the first spring 51 is fixedly connected to the middle of the inner cavity of the mounting shell 41. L-shaped plates 52 are fixedly connected to the upper and lower sides of the side of the mounting bracket 42 away from the belt 45. A guide rod 53 is slidably connected to the inner wall of the mounting shell 41. A push plate 54 is fixedly connected to the middle of the guide rod 53. The outer edge of the push plate 54 is attached to the inner wall of the L-shaped plate 52. The lower ends of both sets of push plates 54 are fixedly connected to sliding frames 55. The lower end of the inner cavity of the mounting shell 41 is fixedly connected to a limit rod 56. The lower middle part of the sliding frame 55 is slidably connected to the outer ring of the limit rod 56. The middle left side of the sliding frame 55 is fixedly connected to a second spring 57. The left end of the second spring 57 is fixedly connected to the left side of the inner cavity of the mounting shell 41. A pull rope 58 is fixedly connected to the middle left side of the push plate 54. The left end of the pull rope 58 passes through the mounting shell 41 and is fixedly connected to the middle upper part of the lifting frame 15.

[0039] It should be noted that the push plate 54 has a trapezoidal structure and a ramp is provided on the side that contacts the L-shaped plate 52. This is intended to allow the push plate 54 to move by using the ramp to push the mounting frame 42 and the conical wheel 43 to move outward from the mounting shell 41, thereby controlling the two sets of conical wheels 43 to move away from each other. The guide rod 53 is a T-shaped structure designed to limit the range of motion of the guide rod 53 and the push plate 54; The inner left side of the mounting housing 41 has a cavity reserved, and the length of the cavity should be greater than the length of the descent process of the lifting frame 15, so that the push plate 54 will not affect the movement process of the lifting frame 15. The second spring 57 is located on the outer ring of the limiting rod 56 to ensure the stability of the contraction of the second spring 57; The sliding frame 55 connects the front and rear push plates 54 together, so that the second spring 57 can simultaneously push the two sets of push plates 54 to reset. Even if the push plate 54 is moved to the far left, the L-shaped plate 52 cannot fit against the inner wall of the mounting shell 41, thereby limiting the sliding range of the conical wheel 43 and avoiding affecting the normal rolling of the belt 45.

[0040] In this embodiment, when the lifting frame 15 is raised or lowered, it pulls the rope 58 to move. When the lifting frame 15 moves downward to adjust the soil turning depth, the rope 58 pulls the push plate 54 to move to the left. The slope of the push plate 54 pushes the L-shaped plate 52, causing the mounting frame 42 and the conical wheel 43 to move to both sides, making the two sets of conical wheels 43 move away from each other. This causes the belt 45 to gradually move towards the center of the conical wheel 43. At this time, the transmission diameter difference between the drive wheel 44 and the conical wheel 43 increases, and the rotational speed of the conical wheel 43 increases accordingly. The transmission rod 47 then drives the piston pump 32 to increase its rotational speed, accelerating the spraying of the repair fluid, thereby adapting to more... The deep tillage operation requires a certain amount of repair fluid. When the lifting frame 15 moves upward to reduce the tillage depth, the pull rope 58 releases the push plate 54, the second spring 57 pushes the sliding frame 55 and the push plate 54 to return to the right, the first spring 51 pushes the mounting frame 42 to drive the conical wheel 43 to move closer to each other, the belt 45 gradually moves towards the outer edge of the conical wheel 43, the rotation speed of the conical wheel 43 decreases accordingly, and the spraying speed of the piston pump 32 also decreases synchronously, thereby reducing the amount of repair fluid sprayed. This achieves automatic adjustment of the amount of repair fluid sprayed according to the tillage depth, without the need for additional manual adjustment, thus improving the automation level of the device and the adaptability of the repair operation.

[0041] The working principle of this invention is as follows: When in use, the device is moved to the soil to be repaired. The hydraulic rod 18 pushes the lifting frame 15 to slide downward in the guide rail 14, causing the turning roller 16 to contact the soil. Then, the drive motor 17 drives the turning roller 16 to rotate, which can turn the soil at different depths. At the same time, the motor 22 drives the rotating shaft 23 and the drive wheel 44 to rotate. At this time, the drive wheel 44 drives two sets of conical wheels 43 to rotate synchronously through the belt 45. The conical wheels 43 then drive the transmission rod 47 to rotate, and the transmission rod 47 drives the piston pump 32 to perform reciprocating suction and discharge operations, transporting the repair liquid stored in the water tank 31 to the spray plate 34 through the water pipe 33. Finally, it is evenly sprayed from the multiple outlets of the spray plate 34 into the interior of the turned soil. When the rotating shaft 23 rotates, it also drives the take-up roller 24 to rotate, so that it continuously releases the film 25. The film 25 adheres to the soil surface after the repair liquid has been sprayed under the guidance of the guide roller 26. The scraper 12 then covers the turned-up soil onto the film for fixation. When the lifting frame 15 is raised or lowered, it pulls the rope 58. When the lifting frame 15 moves downwards to adjust the turning depth, the rope 58 pulls the push plate 54 to the left. The slope of the push plate 54 pushes the L-shaped plate 52, causing the mounting frame 42 and the conical wheel 43 to move to both sides, distancing the two sets of conical wheels 43. This causes the belt 45 to gradually move towards the center of the conical wheel 43. At this time, the transmission diameter difference between the drive wheel 44 and the conical wheel 43 increases, and the rotational speed of the conical wheel 43 increases accordingly. The transmission rod 47 then drives the piston pump 32 to increase its speed, accelerating the repair process. The amount of liquid sprayed is adjusted to match the demand for repair liquid in deeper tillage operations. When the lifting frame 15 moves upward to reduce the tillage depth, the pull rope 58 releases the push plate 54, the second spring 57 pushes the sliding frame 55 and the push plate 54 to return to the right, the first spring 51 pushes the mounting frame 42 to drive the conical wheel 43 to move closer to each other, the belt 45 gradually moves towards the outer edge of the conical wheel 43, the rotation speed of the conical wheel 43 decreases accordingly, and the spraying speed of the piston pump 32 also decreases synchronously, thereby reducing the amount of repair liquid sprayed and realizing automatic adjustment of the amount of repair liquid sprayed according to the tillage depth.
