Description

Technical Field

[0001] This invention belongs to the technical field of soil pollution remediation devices, and specifically relates to a grassland ecological soil degradation remediation device. Background Technology

[0002] Grassland ecosystems, as one of the world's most important terrestrial ecosystems, play crucial ecological roles in water conservation, soil and water retention, climate regulation, and biodiversity maintenance. They are also a vital material foundation for livestock development. However, with the acceleration of industrialization and urbanization, and the increasing frequency of human production activities, grassland soil pollution has become increasingly prominent, posing a serious threat to grassland ecological security, sustainable livestock development, and human health. Therefore, soil remediation devices are needed to restore the soil.

[0003] In existing technologies, soil needs to be turned over and broken up using tillage equipment before spraying remediation fluid using nozzles. In grassland remediation scenarios, the composition of the solution is complex (such as containing microbial communities, chelating agent precipitates, and organic nutrients), and the working environment is often dusty. The nozzles are prone to clogging or damage. When the nozzles become clogged, they need to be replaced, which prevents timely spraying of the solution onto the soil. This results in the concentration of the solution in the soil not reaching the expected level, failing to fully treat pollutants, thus reducing the remediation effect and hindering the improvement of soil remediation efficiency.

[0004] Therefore, it is necessary to invent a grassland ecological soil degradation restoration device to solve the above problems. Summary of the Invention

The other side of the first fixed plate is provided with a first rack. The first rack is meshed with a gear away from the first fixed plate. The rotating rod is fixedly connected to the middle of the gear. The gear meshes with the second rack. The bottom end of the second rack is fixedly connected to the second fixed plate, and the second fixed plate is fixedly connected to the bottom end of the first connecting pipe.

[0011] Furthermore, the first rack, the second rack, the gear, and the rotating rod are all located between the first connecting pipe and the second connecting pipe. Connecting rods are fixedly connected to both sides of the top of the first rack and the second rack. Both ends of the connecting rods are slidably connected to the inner wall of the mounting block. Both ends of the rotating rod are rotatably connected to the inner wall of the mounting block. The first fixing plate and the second fixing plate are both located at the top of the connecting block. The first fixing plate is located at the top of the mounting opening.

[0012] Furthermore, the first fixing plate has two mounting slots on the side near the first rack, and a second electric push rod is fixedly connected in each mounting slot. One end of the second electric push rod passes through the mounting slot and is fixedly connected to a fixing block, which is fixedly connected to both sides of the first rack.

[0013] Furthermore, a protective baffle is slidably connected to the inner wall of the bottom of the mounting block, and an electric telescopic rod is fixedly connected to both sides of the protective baffle. The side of the electric telescopic rod away from the protective baffle is fixedly connected to the inner wall of the mounting block. The number of protective baffles, electric telescopic rods and mounting openings is the same. The protective baffle near the first connecting pipe is located behind the first fixed plate, and the protective baffle near the second connecting pipe is located at the top of the mounting opening at the bottom of the second connecting pipe.

[0014] Furthermore, a sensor is installed inside the nozzle near the connecting block, and an adjustment plate is fixedly connected inside the nozzle away from the connecting block. A moving block is installed inside the adjustment plate, and a groove is opened on the side of the moving block near the adjustment plate.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. This invention allows for the switching between a first connecting pipe and a second connecting pipe, enabling the replacement of clogged or damaged nozzles. This ensures continuous remediation and prevents clogged or damaged nozzles from affecting the spraying effect of the pesticide solution, thus preventing the pesticide concentration in the soil from falling below expectations and failing to fully treat pollutants. The first and second connecting pipes can also accommodate different types of nozzles to suit different pesticide characteristics. Furthermore, when the first connecting pipe and nozzles are in normal use, the second connecting pipe and nozzles can increase the spraying range and area, reducing blind spots and improving the efficiency of soil remediation.

[0019] 2. The present invention can detect impurities in the first and second connecting pipes through sensors. When the impurities in the first and second connecting pipes are too large and block the conveying port, the diameter of the conveying port can be increased by adjusting the position of the moving block. This can remove large particles of impurities from the first and second connecting pipes, reduce the probability of nozzle blockage, and improve the spraying effect and service life of the nozzle.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] This invention provides a device for restoring grassland ecological soil degradation, such as... Figures 1 to 5 As shown, the device includes a vehicle body 1, a mounting block 2 fixedly connected to the vehicle body 1, a medicine storage tank 3 fixedly connected to the top of the mounting block 2, a control box 4 provided on one side of the medicine storage tank 3 and the mounting block 2, and a spraying device provided inside the mounting block 2.

[0033] The spraying device includes a first connecting pipe 5, a second connecting pipe 6, a connecting block 7, a nozzle 8, and an adjustment component. The first connecting pipe 5 and the second connecting pipe 6 are both fixedly connected to the bottom of the storage tank 3. The bottom ends of the first connecting pipe 5 and the second connecting pipe 6 are both fixedly connected to the connecting block 7. The nozzle 8 is fixedly connected to the middle of the connecting block 7. The bottom of the mounting block 2 has an installation port 9. The connecting block 7 at the bottom end of the first connecting pipe 5 is located inside the installation port 9, and the nozzle 8 is located at the bottom of the installation port 9. The connecting block 7 at the bottom end of the second connecting pipe 6 and the nozzle 8 are both located inside the mounting block 2. An adjustment component is provided between the first connecting pipe 5 and the second connecting pipe 6.

[0034] Both the first connecting pipe 5 and the second connecting pipe 6 are equipped with control valves at their top ends. Both the first connecting pipe 5 and the second connecting pipe 6 are made of elastic telescopic material. Multiple sets of the first connecting pipe 5, the second connecting pipe 6, the connecting block 7, and the nozzle 8 are arranged in a linear array. The second connecting pipe 6 is located between two adjacent first connecting pipes 5 and is in a contracted state.

[0035] The mounting block 2 facilitates the installation of the storage tank 3 on the vehicle body 1. The storage tank 3 contains repair fluid. The control box 4 controls the valve to deliver the repair fluid from the first connecting pipe 5 or the second connecting pipe 6 to the nozzle 8. The nozzle 8 sprays the repair fluid onto the soil. As the vehicle body 1 moves, the mounting block 2, the storage tank 3, and the nozzle 8 move, improving the spraying effect and ensuring the sprayed repair fluid effectively treats pollutants in the soil, thus enhancing the repair outcome. The connecting block 7 facilitates the connection between the first connecting pipe 5 or the second connecting pipe 6 and the nozzle 8. Since both the first connecting pipe 5 and the second connecting pipe 6 are made of elastic material, if the nozzle 8 at the bottom of the first connecting pipe 5 becomes blocked or damaged, requiring a switch, the first connecting pipe 5 can be retracted using an adjustment component. The moving nozzle 8 moves into the mounting block 2, causing the second connecting pipe 6 to extend and drive the nozzle 8 through the mounting port 9 to the bottom of the mounting block 2. This allows the nozzle 8 at the bottom of the first connecting pipe 5 and the second connecting pipe 6 to switch, enabling the nozzle 8 at the bottom of the second connecting pipe 6 to continue spraying the pesticide solution without needing to reinstall it. This ensures the continuity of the remediation process and prevents clogged or damaged nozzles 8 from affecting the effectiveness of the pesticide spraying, thus preventing the pesticide concentration in the soil from falling short of expectations. At the same time, different types of nozzles 8 can be installed on the first connecting pipe 5 and the second connecting pipe 6. By switching between the first connecting pipe 5 and the second connecting pipe 6, the nozzle 8 can adapt to the pesticide characteristics of different remediation solutions, allowing it to adapt to different spray atomization effects, improving the contact efficiency between the pesticide and the contaminated soil, and facilitating the improvement of soil remediation results.

[0036] like Figures 3 to 6 As shown, the adjustment assembly includes a first electric push rod 10, a first fixed plate 11, a second fixed plate 12, a gear 13, a rotating rod, a first rack 14 and a second rack 15. The bottom end of the second connecting pipe 6 is fixedly connected to the first fixed plate 11. The first electric push rod 10 is fixedly connected to one side of the first fixed plate 11 and is fixedly connected to the bottom of the medicine storage box 3. The other side of the first fixed plate 11 is provided with a first rack 14. The first rack 14 is meshed with the gear 13 away from the first fixed plate 11. The rotating rod is fixedly connected to the middle of the gear 13. The gear 13 meshes with the second rack 15. The bottom end of the second rack 15 is fixedly connected to the second fixed plate 12. The second fixed plate 12 is fixedly connected to the bottom end of the first connecting pipe 5.

[0037] The first rack 14, the second rack 15, the gear 13, and the rotating rod are all located between the first connecting pipe 5 and the second connecting pipe 6. The top ends of the first rack 14 and the second rack 15 are fixedly connected to the connecting rods 16. Both ends of the connecting rods 16 are slidably connected to the inner wall of the mounting block 2. Both ends of the rotating rod are rotatably connected to the inner wall of the mounting block 2. The first fixing plate 11 and the second fixing plate 12 are both located on the top of the connecting block 7. The first fixing plate 11 is located on the top of the mounting port 9.

[0038] When it is necessary to switch the nozzle 8 at the bottom of the first connecting pipe 5 and the second connecting pipe 6, the first electric push rod 10 is activated to move the first fixing plate 11 downwards. This causes the first fixing plate 11 to extend the second connecting pipe 6, and also causes the connecting block 7 and the nozzle 8 to move downwards. When the first fixing plate 11 moves, the action of the second electric push rod 17 and the fixing block 18 causes the first rack 14 to move the connecting rod 16 downwards along the inner wall of the mounting block 2. This, in turn, causes the gear 13 to drive the rotating rod to rotate along the inner wall of the mounting block 2, improving the stability of the gear 13's rotation. When the gear 13 rotates, it causes the first... The second rack 15 drives the second fixed plate 12 and the connecting rod 16 to move upward, causing the first connecting pipe 5 to retract. Through the action of the connecting block 7, the nozzle 8 at the bottom of the first connecting pipe 5 moves into the mounting block 2. When the nozzle 8 at the bottom of the first connecting block 7 has completely moved into the mounting block 2, the connecting block 7 connected to the second connecting pipe 6 moves into the mounting port 9, and the nozzle 8 at its bottom is located at the bottom of the mounting block 2. Thus, the spraying of the liquid medicine can continue through the nozzle 8 at the bottom of the second connecting pipe 6, improving the continuity of liquid medicine spraying, eliminating the need for frequent replacement of the nozzle 8, and thus improving work efficiency.

[0039] like Figures 6 to 7 As shown, the first fixing plate 11 has two mounting slots on the side near the first rack 14. A second electric push rod 17 is fixedly connected in each mounting slot. One end of the second electric push rod 17 passes through the mounting slot and is fixedly connected to a fixing block 18. The fixing block 18 is fixedly connected to both sides of the first rack 14.

[0040] The mounting slots facilitate the installation of the second electric push rod 17 at both ends of the inner part of the first fixed plate 11. The fixed block 18 and the first rack 14, driven by the second electric push rod 17, move away from the gear 13, thereby disengaging the first rack 14 from the gear 13. At this time, the first electric push rod 10 is activated to move the first fixed plate 11 downward, causing the second electric push rod 17 to extend and move the connecting block 7 into the mounting port 9 at the bottom of the second connecting pipe 6, so that the nozzle 8 is located at the bottom of the mounting block 2. The number of nozzles 8 at the bottom of the mounting block 2 is increased by the nozzles 8 at the bottom of the second connecting pipe 6, thereby increasing the spray range and area of ​​the liquid, allowing a large area of ​​soil to be sprayed with the remediation liquid, reducing blind spots in the spray, and improving the remediation effect.

[0041] like Figures 3 to 5As shown, a protective baffle 19 is slidably connected to the inner wall of the bottom of the mounting block 2. Electric telescopic rods 20 are fixedly connected to both sides of the protective baffle 19. The side of the electric telescopic rod 20 away from the protective baffle 19 is fixedly connected to the inner wall of the mounting block 2. The number of protective baffles 19, electric telescopic rods 20 and mounting ports 9 is the same. The protective baffle 19 near the first connecting pipe 5 is located behind the first fixed plate 11, and the protective baffle 19 near the second connecting pipe 6 is located at the top of the mounting port 9 at the bottom of the second connecting pipe 6.

[0042] The protective baffle 19 at the bottom of the second connecting pipe 6 can block the installation port 9, preventing stones and pebbles in the soil from entering the installation block 2, thus affecting the movement of the adjustment component and the service life of the nozzle 8. When the nozzle 8 at the bottom of the first connecting pipe 5 needs to be moved into the installation block 2, the electric telescopic rod 20 is activated to move the protective baffle 19 to the top of the installation port 9, thereby blocking the installation port 9 at the bottom of the first connecting pipe 5. Then, the electric telescopic rod 20 is activated to move the protective baffle 19 at the bottom of the second connecting pipe 6, exposing the installation block 2, so that the nozzle 8 at the bottom of the second connecting pipe 6 can be moved to the bottom of the installation block 2 for easy spraying of the repair fluid.

[0043] like Figures 8 to 9 As shown, a sensor 21 is installed inside the nozzle 8 near the connecting block 7. An adjustment plate 22 is fixedly connected inside the nozzle 8 away from the connecting block 7. A moving block 23 is installed inside the adjustment plate 22. A groove is opened on the side of the moving block 23 near the adjustment plate 22. The bottom of the moving block 23 is slidably connected to the inner wall of the groove. A third electric push rod 24 is fixedly connected inside the groove.

[0044] Sensor 21 is located on top of adjustment plate 22. A conveying port 25 is provided in the middle of adjustment plate 22. A moving groove is provided inside adjustment plate 22. Moving block 23 is located in conveying port 25. The end of third electric push rod 24 away from moving block 23 extends into moving groove and is fixedly connected to the inner wall of moving groove. The third electric push rod 24 and moving block 23 are distributed in a circular array around the center of adjustment plate 22. One side of two adjacent moving blocks 23 are in contact.

[0045] Sensor 21 is a particle sensor, model PMT-2. It facilitates the spraying of repair fluid from the first connecting pipe 5 or the second connecting pipe 6 through the delivery port 25. When sensor 21 detects large particulate impurities in the first connecting pipe 5 or the second connecting pipe 6, it activates the third electric push rod 24 to move the moving block 23 into the moving groove, thereby increasing the diameter of the delivery port 25. This allows the large particulate impurities to move to the outside of the first connecting pipe 5 or the second connecting pipe 6 through the delivery port 25. After the large particulate impurities are removed, the third electric push rod 24 moves the moving block 23 back to its original position, restoring the diameter of the delivery port 25. This prevents large particulate impurities from clogging the nozzle 8, reduces the probability of nozzle 8 clogging and switching, and improves the spraying effect and service life of the nozzle 8.

[0046] like Figures 8 to 9 As shown, the bottom ends of the first connecting pipe 5 and the second connecting pipe 6 are located in the middle of the connecting block 7. An annular groove is provided on the inner wall of the connecting block 7. A shock-absorbing pad 26 is fixedly connected in the annular groove. The first fixing plate 11 and the second fixing plate 12 are both located on the top of the shock-absorbing pad 26. The shock-absorbing pad 26 is attached to the outer side of the bottom end of the first connecting block 7 and the second connecting pipe 6.

[0047] The annular groove facilitates the installation of the shock-absorbing pad 26, so that when the connecting block 7 is connected to the bottom end of the first connecting pipe 5 or the second connecting pipe 6, the shock-absorbing pad 26 can absorb the vibration generated by the first connecting pipe 5 or the second connecting pipe 6. The stability of the connection part facilitates the delivery of repair fluid by the first connecting pipe 5 or the second connecting pipe 6, thus making it easier to use.

[0048] Working principle of this invention:

[0049] Reference Figures 1 to 10As shown, during use, the control box 4 causes the control valve to deliver the repair fluid from the first connecting pipe 5 or the second connecting pipe 6 to the nozzle 8. When the vehicle body 1 moves, it drives the mounting block 2, the storage tank 3, and the nozzle 8 to move as well. The nozzle 8 sprays the repair fluid onto the soil, allowing the sprayed repair fluid to fully treat the pollutants in the soil. When the nozzle 8 at the bottom of the first connecting pipe 5 becomes blocked or damaged and needs to be switched, firstly, the electric telescopic rod 20 at the bottom of the second connecting pipe 6 is activated to move the protective baffle 19, exposing the mounting port 9 at the bottom of the second connecting pipe 6. Then, the first electric push rod 10 is activated to move the first fixing plate 11 downward, causing the first fixing plate 11 to extend the second connecting pipe 6 and causing the connecting block 7 and the nozzle 8 to move downward. When the first fixing plate 11 moves, through the action of the second electric push rod 17 and the fixing block 18, the first rack 14 drives the connecting rod 16 along the inner wall of the mounting block 2. The gear 13 moves downward, causing the rotating rod to rotate along the inner wall of the mounting block 2. This causes the second rack 15 to move the second fixing plate 12 and the connecting rod 16 upward, causing the first connecting pipe 5 to retract. Through the action of the connecting block 7, the nozzle 8 at the bottom of the first connecting pipe 5 moves into the mounting block 2. When the nozzle 8 at the bottom of the first connecting block 7 is completely moved into the mounting block 2, the connecting block 7 connected to the second connecting pipe 6 moves into the mounting port 9, and the nozzle 8 at its bottom is located at the bottom of the mounting block 2. Thus, the nozzle 8 at the bottom of the second connecting pipe 6 can continue to spray the liquid, improving the continuity of the liquid spraying and eliminating the need for frequent nozzle 8 replacements. After the first connecting pipe 5 and the nozzle 8 move into the mounting block 2, the electric telescopic rod 20 on one side of the second fixing plate 12 is activated, causing the protective baffle 19 to move to the top of the mounting port 9 at the bottom of the first connecting pipe 5, providing protection through the protective baffle 19.

[0050] The second electric push rod 17 drives the fixed block 18 and the first rack 14 to move away from the gear 13, thereby causing the first rack 14 and the gear 13 to no longer mesh. At this time, the first electric push rod 10 is activated to drive the first fixed plate 11 to move downward, causing the second electric push rod 17 to extend and move the connecting block 7 into the mounting port 9 at the bottom of the second connecting pipe 6, so that the nozzle 8 is located at the bottom of the mounting block 2. By increasing the number of nozzles 8 at the bottom of the mounting block 2 through the nozzles 8 at the bottom of the second connecting pipe 6, the spray range and area of ​​the liquid are increased.

[0051] When the first connecting pipe 5 or the second connecting pipe 6 delivers the repair fluid, it is sprayed out from the nozzle 8 through the delivery port 25. When the sensor 21 detects large particulate impurities in the first connecting pipe 5 or the second connecting pipe 6, the third electric push rod 24 is activated to move the moving block 23 into the moving groove, thereby increasing the diameter of the delivery port 25. This allows the large particulate impurities to move to the outside of the first connecting pipe 5 or the second connecting pipe 6 through the delivery port 25. After the large particulate impurities are removed, the third electric push rod 24 moves the moving block 23 back to its original position, restoring the diameter of the delivery port 25, so that the nozzle 8 can continue to spray the repair fluid.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
