Description

Technical Field

[0001] The present invention belongs to the technical field of contaminated soil remediation or landscaping, and in particular to a device and method for remediating contaminated soil in landscaping. Background Art

[0002] In recent years, with the acceleration of industrialization, soil pollution has become increasingly serious, posing a serious threat to the ecological environment and human health. In order to meet this challenge, soil remediation technology has developed rapidly. Soil remediation is a technical measure to restore the normal function of contaminated soil. Through physical, chemical or biological methods, the original function of the soil can be effectively treated and restored, reducing the threat to the ecological environment, food safety and human health.

[0003] ‌‌Among them, physical methods include heat treatment, excavation, etc. ‌Chemical methods‌: such as chemical leaching, chemical oxidation, etc. ‌Biological methods‌ utilize in situ microbial remediation technology and ex situ microbial remediation technology. Among the many soil remediation methods, using remediation agents to treat contaminated soil is a common and effective method. Remediation agents for contaminated soil are products specifically used to treat and restore the quality of contaminated soil. Remediation agents use different mechanisms to improve the properties of contaminated soil, accelerate the self-repair process, or reduce the concentration and toxicity of pollutants. They include organic, inorganic, and biological types. Through physical, chemical or biological mechanisms of action, they are scientifically proportioned and applied to the soil in appropriate amounts to significantly improve the soil environment, increase fertility, promote plant growth, and effectively reduce the harm of pollutants to the environment and human body.

[0004] However, in the existing contaminated soil remediation treatment, soil turning devices, soil screening devices, and remediation agent spraying devices are commonly used. However, after long-term use by environmental protection personnel, it is found that the above devices still generally have the following problems: Question 1: During the use of the soil turning device, the folding height of the soil turning mechanism on the soil turning device is usually low. When driving on some places with high slopes, it may bump into it, causing damage to the soil turning mechanism.

[0005] Question 2: When screening the soil, the loose soil is sent into the screening device and then screened. The steps are cumbersome, which will increase working time and time cost.

[0006] Question 3: When using remediation agents to repair contaminated soil, the spraying device can only spray the remediation agent on the surface of the soil and cannot deeply integrate into the middle and bottom of the soil, thereby reducing the efficiency of soil pollution remediation.

[0007] Question 4: In actual application, soil remediation agents often have problems such as long remediation cycle and easy volatility of remediation agents during the remediation process. Therefore, in view of the above problems, the present invention proposes a device and method for remediating contaminated soil in landscaping. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Beneficial effects of soil turning device: 1.1. The soil turning device starts the rotating motor by making the soil turning gear in the protective shell contact with the garden ground, and the rotating motor drives the soil turning gear to rotate, so as to rotate and turn the soil. After turning the soil; the user starts the driving motor, and the driving motor drives the first transmission wheel to rotate, and the first transmission wheel drives the first rack transmission belt to rotate, and the first rack transmission belt drives the second transmission wheel to rotate, and the first transmission wheel and the second transmission wheel simultaneously drive the first threaded rod to rotate, and the first threaded rod drives the first moving block to move, and the first moving block drives the first connecting rod to move, and the first connecting rod drives the protective shell to move, thereby driving the soil turning gear to move, and retracting it so that it is located at a higher position, reducing damage to it when passing through a higher ramp, making it convenient for users to retract and use it, and reducing damage to the soil turning gear.

[0014] 1.2. The soil turning device is driven by a servo motor, which drives the driving wheel to rotate, the driving wheel drives the second rack transmission belt to rotate, the second rack transmission belt drives the driven wheel to rotate, the driving wheel and the driven wheel drive the second threaded rod to rotate, the second threaded rod drives the second moving block to move, the second moving block drives the connecting block to move, the connecting block drives the moving rod to move, the moving rod drives the solar panel to adjust the angle through the connecting column, thereby adjusting the angle of the solar panel to facilitate adjustment according to needs, thereby expanding the adaptability of the solar panel.

[0015] 2. Beneficial effects of soil screening device: 2.1. When the soil screening device screens the soil, the loose soil is sent into the screening device for screening. The steps are cumbersome and will increase the working time and time cost. The solid waste is directly sent into the main body of the screening device by rotating the roller body above the soil, and the soil and waste are separated by vibration, which saves the step of soil screening. At the same time, the infusion pump cooperates with the decomposition liquid outlet hole to spray the decomposition liquid on the turned-up soil to reduce the soil viscosity, thereby improving the screening efficiency.

[0016] 2.2. When the main body of the soil screening device is dragged on the ground, the long-term movement on the ground may accelerate the wear of the bottom of the main body of the screening device and reduce its service life. Therefore, the main body of the screening device is protected by a protective plate to reduce the wear rate of the main body of the screening device. The use of spring columns increases the vibration amplitude inside the main body of the screening device, further improving the screening efficiency.

[0017] 3. Beneficial effects of the repair agent spraying device: 3.1. The repair agent spraying device removes the stones, solid waste and hard soil blocks inside the contaminated soil, and then flows the loose contaminated soil into the mixing drum through the feeding pipe, and then turns on the motor to drive the positioning rod to rotate, so that the positioning rod drives the positioning plate to rotate, so that the positioning plate drives the fixed pipe to rotate at the bottom of the sealing pipe, and when the fixed pipe rotates, it drives the spraying pipe to rotate, so that the spraying pipe drives the fixed seat and the stirring rod to rotate, so as to stir the loose contaminated soil at the bottom of the mixing drum. During the stirring process, the loose contaminated soil at the bottom of the mixing drum is stirred by the inside of the circulation pipe. Pour the repair agent into the container, so that the repair agent flows through the circulation pipe to the inside of the sealing pipe, and then flows through the sealing pipe to the circulation cavity inside the fixed pipe and the spraying pipe. With the rotation, the fixed rod at the end of the fixed pipe drives the sealing plate to open to the side, and then the slot is opened, so that the repair agent contained in the circulation cavity flows through the guide pipe to the end of the slot, and is sprayed out to the outside with the centrifugal force generated by the rotation to mix in the contaminated soil. The stirring rod is used for stirring, so that the repair agent is fully integrated into the contaminated soil to repair the soil, thereby improving the absorption efficiency of the repair agent.

[0018] 3.2 In the repair agent spraying device, when the positioning rod rotates, it drives the first support rod and the first scraper to rotate, so that the first scraper scrapes the repair agent at the bottom of the sealing tube and then flows into the interior of the fixed tube, reducing the problem of sinking to the bottom.

[0019] 4. Beneficial effects of soil remediation film covering device: 4.1. The soil remediation film covering device is driven by the movement of the tractor, so that the plastic film covers the soil mixed with the repair agent as the tractor moves, and at the same time, the guided soil is pressed against the two ends of the plastic film through the tillage block, thereby reducing the volatilization of the repair agent in the soil, while maintaining the moisture and temperature of the soil, thereby accelerating the repair speed and degree of the repair agent.

[0020] 4.2. The soil remediation covering device adjusts the total weight of the upper end of the device by flexibly configuring different numbers of weights, thereby controlling the sinking depth of the cultivated soil block in the soil, so that the device can adapt to soils of various hardnesses.

[0041] The working principle of the soil screening device is that the installation device body A1 is installed behind the tiller. When the installation device body A1 is dragged and moved, the roller body A11 starts to rotate, and the soil and some solid garbage are pushed into the screening device body A12, and then the larger pieces of garbage are filtered out through the filter plate A13. Then, these soil and garbage roll down behind the screening device body A12. At the same time, the roller body A11 rotates while driving the belt A14 to rotate above the installation plate A19, driving the knocking block A15 to rotate, and continuously knocking the vibration block A16, so that the soil inside the screening device body A12 is shaken down through the filter plate A13, completing the separation of soil and solid garbage.

Therefore, the screening device body A12 is protected by the protective plate A2, which reduces the wear rate of the screening device body A12. When the spring column A21 is used, the vibration amplitude inside the screening device body A12 is increased, and the screening efficiency is further improved.

At this time, the second servo motor A3 is driven to drive the feeding roller A31 to start rotating, and the garbage is transported through the feeding roller A31, and then passed through the waste discharge The soil is discharged through the port A32. When the soil is screened again, if too much garbage is accumulated inside the screening device body A12, it may increase the load of the device. Therefore, the garbage inside the screening device body A12 is cleaned regularly by the feeding roller A31, which increases the cleanliness inside the screening device body A12, reduces the load of the device, and increases the service life of the device. When the protective plate A2 is dragged, the roller A41 inside the circular groove A4 starts to rotate. The use of the circular groove A4 reduces the contact area between the protective plate A2 and the ground, reduces the friction between the protective plate A2 and the ground, and increases the service life of the protective plate A2.

[0056] Example 2 A method for repairing polluted soil in landscaping includes the following methods: The repair method of the soil turning device is as follows: the turning gear 113 in the protective shell 111 is brought into contact with the garden ground to start the rotating motor 112, and the rotating motor 112 drives the turning gear 113 to rotate, so as to turn the soil. After turning the soil; the user starts the driving motor 104, and the driving motor 104 drives the first transmission wheel 105 to rotate, and the first transmission wheel 105 drives the first rack transmission belt 106 to rotate, and the first rack transmission belt 106 drives the second transmission wheel 107 to rotate, and the first transmission wheel 105 and the second transmission wheel 107 simultaneously drive the first threaded rod 108 to rotate, and the first threaded rod 108 drives the first moving block 109 to move, and the first moving block 109 drives the first The connecting rod 110 moves, and the first connecting rod 110 drives the protective shell 111 to move, thereby driving the soil turning gear 113 to move, and fold it up so that it is located at a higher position, reducing damage to it when passing through a higher ramp, making it convenient for users to fold it up and use it, reducing damage to the soil turning gear 113, and through the first servo motor 202, the first servo motor 202 drives the driving wheel 203 to rotate, the driving wheel 203 drives the second rack transmission belt 204 to rotate, the second rack transmission belt 204 drives the driven wheel 205 to rotate, the driving wheel 203 and the driven wheel 205 drive the second threaded rod 206 to rotate, the second threaded rod 206 drives the second moving block 207 to move, and the second moving block 207 drives the connecting block 208 to move, the connecting block 208 drives the moving rod 209 to move, the moving rod 209 drives the solar panel 102 to adjust the angle through the connecting column 210, thereby adjusting the angle of the solar panel 102, which is convenient for adjustment according to needs, thereby expanding the adaptability of the solar panel 102, the second moving block 207 drives the guide slider 3 to slide on the guide slider 301, and guides the guide slider 3 horizontally, thereby guiding the second moving block 207 horizontally, making it easier for the second moving block 207 to move, reducing the wear of the second moving block 207, the first moving block 109 drives the limit slider 401 to slide on the limit slider 402, The limit slider 401 is limited and guided, thereby limiting and guiding the first moving block 109, so that the first moving block 109 can move more easily as the first threaded rod 108 rotates. The blocking plate 5 blocks the moving rod 209 to prevent the moving rod 209 from being separated from the connecting column 210, thereby reducing the impact on the operation of the moving rod 209. The first threaded rod 108 rotates in the frame 101 through the first limit bearing 6, which limits the first threaded rod 108 and reduces the wear of the first threaded rod 108. The second threaded rod 206 rotates on the first connecting plate 2 through the second limit bearing 7, which limits the second threaded rod 206 and reduces the wear of the second threaded rod 206.

[0057] Repair and treatment method of soil screening device: install the installation device body A1 behind the tiller. When the installation device body A1 is dragged and moved, the roller body A11 starts to rotate, and the soil and some solid garbage are pushed into the screening device body A12, and then the larger pieces of garbage are filtered out through the filter plate A13. Then, these soil and garbage roll down behind the screening device body A12. At the same time, the rotation of the roller body A11 drives the belt A14 to rotate above the installation plate A19, drives the knocking block A15 to rotate, and continuously knocks the vibration block A16, so that the soil inside the screening device body A12 is shaken down through the filter plate A13, and the soil and solid garbage are separated. The decomposition liquid is filled in the infusion pump A17, and the decomposition liquid is discharged during rotation. Liquid hole A18 is spilled, and when the soil is screened, the loose soil is sent into the screening device for screening, which is cumbersome and will increase working time and time cost. The solid waste is directly sent into the screening device body A12 by rotating the roller body A11 above the soil, and the soil and waste are separated by vibration, which saves the step of soil screening. At the same time, the infusion pump A17 cooperates with the decomposition liquid outlet hole A18 to spray the decomposition liquid on the turned-up soil to reduce the viscosity of the soil, thereby improving the screening efficiency. First, the spring column A21 inside the protection plate A2 is installed at the bottom of the screening device body A12. At this time, the slider A22 is inside the slide groove A23, and then the special-shaped screw A24 is raised and rotated to be installed inside the slide groove A23, passing through Slider A22, when the screening device body A12 is dragged on the ground, the protection plate A2 contacts the ground. When the screening device body A12 is dragged on the ground, the long-term movement on the ground may accelerate the wear of the bottom of the screening device body A12 and reduce the service life. Therefore, the screening device body A12 is protected by the protection plate A2 to reduce the wear rate of the screening device body A12. When the spring column A21 is used, the vibration amplitude inside the screening device body A12 is increased, and the screening efficiency is further improved. After the solid waste inside the soil is separated, it will approach the feeding roller A31 due to vibration. At this time, the second servo motor A3 is driven to drive the feeding roller A31 to start rotating, and the garbage is transported through the feeding roller A31, and then passed through the discharge The waste outlet A32 is discharged, and when the soil is screened again, if there is too much garbage accumulated inside the screening device body A12, it may increase the load of the device, so the garbage inside the screening device body A12 is cleaned regularly by the feeding roller A31, which increases the cleanliness inside the screening device body A12, reduces the load of the device, and increases the service life of the device. When the protective plate A2 is dragged, the roller A41 inside the circular groove A4 starts to rotate. The use of the circular groove A4 reduces the contact area between the protective plate A2 and the ground, reduces the friction between the protective plate A2 and the ground, and increases the service life of the protective plate A2. The telescopic rod A5 drives the scraper A51 to slide on the bottom of the screening device body A12 to clean the bottom of the filter plate A13. During use,Some dirt will adhere to the bottom of the screening device body A12, which may cause the filter plate A13 to be blocked. Therefore, the bottom of the screening device body A12 is cleaned by the scraper A51 to reduce the possibility of the filter plate A13 being blocked. When the slider A22 slides inside the slide groove A23, the buffer spring A6 buffers the slider A22, reducing the possibility of the slider A22 being damaged due to frequent collisions inside the slide groove A23. When the special-shaped screw A24 is installed inside the slide groove A23, the gasket A7 is tightly attached to the special-shaped screw A24. The use of the gasket A7 can increase the contact surface between the special-shaped screw A24 and the workpiece, reducing the possibility of the screw being sent due to vibration.

[0058] Repair treatment method of the repair agent spraying device: When the contaminated soil needs to be repaired, the stones, solid garbage and hard soil blocks inside the contaminated soil are removed, and then the loose contaminated soil is circulated into the inside of the mixing drum B21 through the feeding pipe B22, and then the motor B25 is turned on to drive the positioning rod B34 to rotate, so that the positioning rod B34 drives the positioning plate B35 to rotate, so that the positioning plate B35 drives the fixed pipe B27 to rotate at the bottom of the sealing pipe B26, and when the fixed pipe B27 rotates, it drives the spraying pipe B28 to rotate, so that The spraying pipe B28 drives the fixing seat B36 and the stirring rod B37 to rotate to stir the loose contaminated soil at the bottom of the mixing drum B21. During the stirring process, the repair agent is poured into the inside of the circulation pipe B24, so that the repair agent flows through the circulation pipe B24 to the inside of the sealing pipe B26, and then flows through the sealing pipe B26 to the fixed pipe B27 and the circulation cavity B29 inside the spraying pipe B28. As the rotation occurs, the third fixing rod B32 at the end of the fixed pipe B27 drives the sealing plate B33 to open to the side, and then opens the slot, so that the circulation cavity B2 The repair agent contained in 9 flows through the guide pipe B31 to the end of the card slot, and is sprayed and flowed out to the outside with the centrifugal force generated by the rotation, and is mixed in the contaminated soil. The stirring rod B37 is used for stirring, so that the repair agent is fully integrated into the contaminated soil to repair the soil, thereby improving the absorption efficiency of the repair agent; when the positioning rod B34 rotates, it drives the first support rod B41 and the first scraper B42 to rotate, so that the first scraper B42 scrapes the repair agent at the bottom of the sealing tube B26, and then flows to the inside of the fixed tube B27, reducing the problem of sinking to the bottom. The second support rod B51 and the second scraper B52 are fixedly connected on both sides of the fixed seat B36 to scrape off the contaminated soil adhering to the inner wall of the mixing drum B21, thereby further improving the remediation effect of the contaminated soil; a cross bar B38 is installed at the end of the stirring rod B37 so that the stirring rod B37 drives the cross bar B38 to rotate when it rotates, thereby fully stirring the middle area of ​​the contaminated soil; a support leg B61 ​​and a support pad B62 are installed at the bottom of the base B1 to improve the overall stability of the base B1 and the mixing drum B21.

[0059] The repair treatment method of the soil repair covering device is as follows: by sliding the third connecting rod C105 and the third threaded rod C106 into the inner side of the plastic film C107, and then rotating the threaded cap C108 so that the two threaded caps C108 are threadedly connected to the third threaded rod C106, and then sinking the cultivated soil block C103 to the inner side of the soil, and then covering one end of the plastic film C107 with the soil mixed with the repair agent, and compacting the end of the plastic film C107 with the soil, and then connecting the device to the tractor through the tractor connecting device, and starting the tractor to drive the device to move. When the device moves, the end of the plastic film C107 is compacted by the soil, thereby causing the rotating shaft C104 to rotate, and then the plastic film C107 moves along The tractor moves to cover the soil mixed with the repair agent, and at the same time, the soil is guided to the two ends of the plastic film C107 by the tillage block C103, so that the device covers the soil mixed with the repair agent, and at the same time, the soil guided by the tillage block C103 presses the two ends of the plastic film C107. In this step, the movement of the tractor drives the device to move, so that the plastic film C107 covers the soil mixed with the repair agent as the tractor moves, and at the same time, the guided soil is pressed on the two ends of the plastic film C107 by the tillage block C103, thereby reducing the volatilization of the repair agent in the soil, while maintaining the moisture and temperature of the soil, thereby accelerating the repair speed and degree of the repair agent, and by placing different numbers of weights C203, the weights on the upper end of the device are adjusted. The amount of soil guided by the tillage block C103 is different, and then the depth of the soil block C103 sinking into the soil is adjusted according to the hardness of the soil. In this step, the total weight of the upper end of the device is adjusted by flexibly configuring different numbers of weights C203, so as to control the sinking depth of the tillage block C103 in the soil, so that the device can adapt to soils of various hardnesses. The film pressing block C302 is placed on the outside of the plastic film C107, and the second connecting plate C102 cooperates with the limiting plate C401 to increase the amount of soil guided by the tillage block C103. In this step, the second connecting plate C102 cooperates with the limiting plate C401 to increase the amount of soil at both ends of the plastic film C107 guided by the tillage block C103, so that the soil presses the plastic film C107 more stably. The second fixing block C501 cooperates with the first latch C502, and the second latch C505 cooperates with the connecting frame C504, so that the device is connected to the rear end of the tractor. In this step, the second fixing block C501 cooperates with the first latch C502, and the second latch C505 cooperates with the connecting frame C504, so that the device is connected to the rear end of the tractor, so that the device moves with the tractor. When the tillage block C103 sinks to the inside of the soil, the soil entering the inside of the tillage block C103 is reduced, so that most of the soil is at the upper end of the tillage block C103, thereby increasing the weight of the soil at both ends of the subsequent plastic film C107, and then compacting the plastic film C107 through the soil.The soil is controlled to fall to the positions at both ends of the soil through the excavation plate C701.

The first threaded rod (108) is driven to rotate, the first threaded rod (108) drives the first moving block (109) to move, the first moving block (109) drives the first connecting rod (110) to move, the first connecting rod (110) drives the protective shell (111) to move, thereby driving the soil turning gear (113) to move, and retracting it so that it is located at a higher position, reducing damage to it when passing through a higher ramp, making it convenient for users to retract it for use, reducing damage to the soil turning gear (113), and through the first servo motor (202), the first servo motor (202) drives the driving wheel (203) to rotate, and the driving wheel (203) The second rack transmission belt (204) is driven to rotate, the second rack transmission belt (204) drives the driven wheel (205) to rotate, the driving wheel (203) and the driven wheel (205) drive the second threaded rod (206) to rotate, the second threaded rod (206) drives the second moving block (207) to move, the second moving block (207) drives the connecting block (208) to move, the connecting block (208) drives the moving rod (209) to move, and the moving rod (209) drives the solar panel (102) to adjust the angle through the connecting column (210); the second moving block (207) drives the guide slider (3) on the guide slider (301) The first movable block (109) drives the limiting slider (401) to slide on the limiting slider (402), limits the limiting slider (401), and limits the first movable block (109); the first threaded rod (108) rotates in the frame (101) through the first limiting bearing (6), and limits the first threaded rod (108); the second threaded rod (206) rotates on the first connecting plate (2) through the second limiting bearing (7), and limits the second threaded rod (206); The repair and treatment method of the soil screening device is as follows: the installation device body (A1) is installed at the rear of the tiller. When the installation device body (A1) is dragged and moved, the roller body (A11) starts to rotate, and the soil and some solid garbage are pushed into the screening device body (A12). Then, the larger pieces of garbage are filtered out through the filter plate (A13). Then, the soil and garbage first roll down behind the screening device body (A12). At the same time, the roller body (A11) rotates and drives the belt (A14) at the same time. The device rotates above the mounting plate (A19), driving the knocking block (A15) to rotate, continuously knocking the vibration block (A16), and shaking the soil inside the screening device body (A12) down through the filter plate (A13), completing the separation of the soil and solid waste. The infusion pump (A17) is filled with decomposition liquid, and the decomposition liquid is sprayed out through the liquid outlet (A18) during rotation. At the same time, the infusion pump (A17) cooperates with the decomposition liquid outlet (A18) to spray the decomposition liquid on the turned-up soil to reduce soil stickiness. First, install the spring column (A21) inside the protection plate (A2) at the bottom of the screening device body (A12). At this time, the slider (A22) is inside the slide groove (A23). Then, the special-shaped screw (A24) is raised and rotated to be installed inside the slide groove (A23) and pass through the slider (A22). When the screening device body (A12) is dragged on the ground, the protection plate (A2) contacts the ground. When the protection plate (A2) is dragged, the roller (A41) inside the circular groove (A4) starts to rotate. The use of the circular groove (A4) reduces the contact area between the protection plate (A2) and the ground; when the spring column (A21) is used, the vibration amplitude inside the screening device body (A12) increases, thereby improving the screening efficiency. After the solid waste inside the soil is separated, it will move closer to the feeding roller (A31) due to vibration. At this time, the second servo motor (A3) is driven to drive the feeding roller (A31) to start rotating, and the waste is transported through the feeding roller (A31) and then discharged through the waste outlet (A32); The telescopic rod (A5) drives the scraper (A51) to slide at the bottom of the screening device body (A12) to clean the bottom of the filter plate (A13); when the slider (A22) slides inside the slide groove (A23), the buffer spring (A6) buffers the slider (A22); when the special-shaped screw (A24) is installed inside the slide groove (A23), the gasket (A7) is tightly attached to the special-shaped screw (A24), and the use of the gasket (A7) can increase the contact surface between the special-shaped screw (A24) and the workpiece; The repair treatment method of the repair agent spraying device: when the contaminated soil needs to be repaired, the stones, solid waste and hard soil blocks inside the contaminated soil are removed, and then the loose contaminated soil is circulated into the inside of the mixing drum (B21) through the feeding pipe (B22), and then the motor (B25) is turned on to drive the positioning rod (B34) to rotate, so that the positioning rod (B34) drives the positioning plate (B35) to rotate, so that the positioning plate (B35) drives the fixed pipe (B27) to rotate at the bottom of the sealing pipe (B26), and when the fixed pipe (B27) rotates The spray pipe (B28) is driven to rotate, so that the spray pipe (B28) drives the fixed seat (B36) and the stirring rod (B37) to rotate, so as to stir the loose contaminated soil at the bottom of the stirring drum (B21). During the stirring process, the repair agent is poured into the inside of the circulation pipe (B24), so that the repair agent flows through the circulation pipe (B24) to the inside of the sealing pipe (B26), and then flows through the sealing pipe (B26) to the fixed pipe (B27) and the circulation cavity (B29) inside the spray pipe (B28). As the rotation occurs, the end of the fixed pipe (B27) is The third fixing rod (B32) drives the sealing plate (B33) to open to the side, and then opens the slot, so that the repair agent contained in the flow chamber (B29) flows through the guide pipe (B31) to the end of the slot, and is sprayed and discharged to the outside with the centrifugal force generated by the rotation, and is mixed in the contaminated soil, and is stirred in conjunction with the stirring rod (B37); when the positioning rod (B34) rotates, it drives the first support rod (B41) and the first scraper (B42) to rotate, so that the first scraper (B42) scrapes off the repair agent at the bottom of the sealing tube (B26), and then flows to the fixed The inside of the tube (B27) is provided to reduce the problem of sinking to the bottom; the second support rod (B51) and the second scraper (B52) are fixedly connected to both sides of the fixed seat (B36) to scrape away the contaminated soil adhering to the inner wall of the mixing drum (B21); a cross bar (B38) is installed at the end of the stirring rod (B37) so that the stirring rod (B37) drives the cross bar (B38) to rotate when the stirring rod (B37) rotates, thereby fully stirring the middle area of ​​the contaminated soil; a support leg (B61) and a support pad (B62) are installed at the bottom of the base (B1); The repair method of the soil repair covering device is as follows: the third connecting rod (C105) and the third threaded rod (C106) are slid into the inner side of the plastic film (C107), and then the threaded cap (C108) is rotated so that the two threaded caps (C108) are threadedly connected to the third threaded rod (C106), and then the cultivated soil block (C103) is sunk to the inner side of the soil, and then one end of the plastic film (C107) is used to cover the soil mixed with the repair agent, and the end of the plastic film (C107) is compacted by the soil, and then the device is connected to the tractor through the tractor connecting device, and the tractor is started to drive the device to move. When the device moves, Since the ends of the plastic film (C107) are compacted by the soil, the rotating shaft (C104) rotates, and the plastic film (C107) covers the soil mixed with the repair agent as the tractor moves; at the same time, the soil is guided to the two ends of the plastic film (C107) by the tillage block (C103), so that the device covers the soil mixed with the repair agent, and at the same time, the soil guided by the tillage block (C103) presses the two ends of the plastic film (C107). In this step, the movement of the tractor drives the device to move, so that the plastic film (C107) covers the soil mixed with the repair agent as the tractor moves, and at the same time, the tillage block (C103) 03) Press the guided soil on both ends of the plastic film (C107) to reduce the volatilization of the repair agent in the soil, while maintaining the moisture and temperature of the soil, thereby accelerating the repair speed and degree of the repair agent. By placing different numbers of weights (C203), the weight of the upper end of the device is different, and then the depth of the cultivated soil block (C103) sinking into the soil is adjusted according to the hardness of the different soils. In this step, the total weight of the upper end of the device is adjusted by flexibly configuring different numbers of weights (C203), thereby controlling the sinking depth of the cultivated soil block (C103) in the soil, so that the device can adapt to soils of various hardnesses. Place the film pressing block (C302) on the plastic film. The outer side of the plastic film (C107) is connected to the second connecting plate (C102) and the limiting plate (C401) to increase the amount of soil guided by the tillage block (C103). In this step, the second connecting plate (C102) and the limiting plate (C401) cooperate with each other to increase the amount of soil guided by the tillage block (C103) at both ends of the plastic film (C107), thereby making it more stable when the soil presses the plastic film (C107). The second fixing block (C501) cooperates with the first latch (C502), and the second latch (C505) cooperates with the connecting frame (C504), so that the device is connected to the rear end of the tractor;The second fixing block (C501) cooperates with the first latch (C502), and the second latch (C505) cooperates with the connecting frame (C504), so that the device is connected to the rear end of the tractor, so that the device moves with the movement of the tractor. When the tillage block (C103) sinks to the inside of the soil, the soil entering the inside of the tillage block (C103) is reduced, so that most of the soil is at the upper end of the tillage block (C103), thereby increasing the weight of the soil at both ends of the subsequent plastic film (C107), and then the plastic film (C107) is compacted by the soil, and the soil is controlled to fall to the positions distributed at both ends of the soil through the unearthing plate (C701). ;
