Then, citric acid with a concentration of is sprayed on the soil surface to promote the complexation and precipitation of heavy metal ions. During the repair process, the regulating motor 26 drives the toggle rod 24 to periodically to toggle the soil. In the storage chamber 3 for fourth-level soils such as hard clay, medium-dense clay containing a large amount of crushed stone and gravel, and hard saline soil, the difficulty in repair is the high cost of mechanical crushing and the close combination of pollutants and gravel. Before the fourth-level soil enters the storage chamber 3 through the three-way valve 10, the crushing valve at the rear side of the outer currency of the storage chamber 3 for storing the fourth-level soil is used. The crushing unit 44 crushes the soil, and after completion, the soil enters the storage chamber 3. The controller 2 controls the switching nozzle 39 to spray 10% of the cement-based curing agent stored in the adjustment box 40 on the soil surface. During the spraying process, the vibration unit 41 vibrates continuously, and the adjustment motor 26 drives the toggle rod 24 to periodically toggle the soil. At the same time, the connecting valve 8 is controlled to connect the drying box 12 and the storage chamber 3. The hot air generated by the hot air blower 17 is heated from the air outlet 42 through the connecting valve 8 to the inside of the storage chamber 3. The repair status of the soil in the storage chamber 3 is detected by the detection unit 13 installed on the rear side of the fill light 22 inside the storage chamber 3.

The toggle lever 24 is connected to the adjustment motor 26 installed on the rear side of the outer wall of the box body 1 through a connecting shaft. A temperature and humidity sensor 23 is installed in the middle of the inner wall of the storage chamber 3; The regulating motor 26 is connected to the switching nozzle 39 via a connecting shaft, and the switching nozzle 39 is connected to the regulating box 40 via a connecting pipe. A crushing unit 44 is installed on the upper side of the outer wall of the regulating box 40.

The soil changes and vegetation changes are recorded and observed, so as to propose response measures, which can avoid untimely response to emergencies, and can further optimize the soil performance after repairing the soil, so that the soil area can better adapt to vegetation planting and climate.

[0028] Working principle: After the operator puts the soil to be cultivated into the feed port 4, the controller 2 controls the adapter 14 to connect the rotating shaft 7 and the intercepting motor 15, and the cover 6 is rotated to cover the feed port 4 under the drive of the intercepting motor 15, and the cover 6 is fixed by the fixer 43. The controller 2 controls the adapter 14 to connect the output end of the intercepting motor 15 and the telescopic box 11, and the telescopic box 11 located in the contracted state on the lower side of the inner wall of the drying box 12 is extended to sample the soil, and then retracted into the drying box 12. The controller 2 controls the adapter 14 to connect the output end of the intercepting motor 15 with the hot air blower 17, driving the hot air blower 17 to rotate and blow out hot air to dry the sample soil in the telescopic box 11. When the detection unit 13 detects that the humidity of the sample soil is lower than 5%, the drying is stopped. Then the controller 2 controls the detection unit 13 to detect the sample soil and transmit the detection result to the controller 2. The controller 2 grades the soil in the feed port 4 according to the detection result. The spectral characteristics of the soil are near-infrared. The soil with higher reflectivity in the outer band and obvious organic matter spectral absorption peak is first-class soil, the soil with obvious spectral characteristics of clay mineral hydroxyl absorption peak and decreased reflectivity in the area with higher water content is second-class soil, the soil with stable spectral characteristics of clay mineral absorption peak and difference in the visible short-wave infrared band of gravel component is third-class soil, the soil with obvious rock mineral reflection peak and weak clay spectral signal is fourth-class soil, after being detected by the detection unit 13, the soil is then controlled to open the connecting valve 8 connecting the feed port 4 and the corresponding diversion pipe 9 according to the soil classification, and the first output end of the corresponding three-way valve 10 is connected to the corresponding storage chamber 3, and the soil passes through the connecting valve 8 from the diversion pipe 9 through the three-way valve 10 into the storage chamber 3. After the process is completed, the controller 2 controls the intercepting motor 15 to push the telescopic box 11 out, retract the telescopic plate 16 at the bottom of the telescopic box 11, and drop the soil sample in the telescopic box 11 from the telescopic box 11 into the feed port 4, wait for cleaning, restore the telescopic plate 16 and recycle the telescopic box 11 into the drying box 12; After the soil is transported into the storage chamber 3 by the classification module, the controller 2 cuts off the connection between the first output end of the three-way valve 10 and the storage chamber 3, and connects the second output end of the three-way valve 10 to the recovery pipe 18. The controller 2 controls the pressure motor 37 to drive the push rod 36 to pull the piston 35 backward, so that the water in the water tank 5 enters the pressure unit through the water inlet 33, and then pushes the push rod 36 forward by the pressure motor 37, so that the piston 35 squeezes the water flow and leads to the connecting pipe 20 through the water outlet 34. The connecting valve 8 connected to the connecting pipe 20 is opened, and the water flows into the feed port 4 to flush the feed port 4. The connecting valve 8 connected to the diversion pipe 9 is opened, so that the water in the feed port 4 flows out along the diversion pipe 9 through the second output end of the three-way valve 10 and enters the recovery box 19 from the recovery pipe 18. During the cleaning process, the controller 2 controls the intercepting motor 15 to extend the telescopic box 11, and at the same time as cleaning the feed port 4, the dried soil in the telescopic box 11 is flushed away, and the operation is repeated to clean the classification module to prevent soil residue from affecting subsequent detection and classification. Then the controller 2 controls the connecting valve 8 to connect the drying box 12 and the feed port 4, and connects the intercepting motor 15 and the hot air blower 17 through the adapter 14 to generate hot air, and connects the drying box 12 and the feed port 4 through the connecting valve 8 to dry the classification module. During the drying process, the controller 2 controls the fixer 43 to release the fixation of the lid 6, and the intercepting motor 15 drives the rotating shaft 7 to slowly open the lid 6 to avoid excessive pressure inside the classification module. After the lid 6 is fully opened, the operator adds soil for the second time; After the cleaning module has cleaned up the residual soil after classification by the classification module and put it into the recycling box 19, the controller 2 controls the feeding valve 28 to open and add the flocculant placed in the storage box 29 into the recycling box 19, and then closes the feeding valve 28. The controller 2 controls the processing motor 32 located on the upper side of the recycling box 19 to drive the stirring rod 31 to stir at a speed of 100rpm / min to 160rpm / min. At this time, the telescopic rod 30 is in a retracted state, that is, the stirring rod 31 is located in the middle and upper part of the inner wall of the recycling box 19. After stirring for 1min to 3min, the controller 2 controls the processing motor 32 to drive the telescopic rod 30 to lower the position of the stirring rod 31 to the middle and lower part of the inner wall of the recycling box 19, and at the same time reduces the speed of the stirring rod 31 to 20rpm / min to 40rpm / min, stirs for 5min to 10min, and then stands for 10min to 30min. After the processing is completed, the controller 2 controls the reflux valve 27 to open, and introduces the treated water flow from the upper part of the recycling box 19 into the water tank 5 for replenishment, and is located in the reflux The mixture of flocculated sediment and a small amount of water at the bottom of the collection box 19 re-participates in the flocculation reaction in the newly added soil-water mixture during the subsequent cleaning process. At this time, the controller 2 extends the telescopic rod 30 downward through the processing motor 32, so that the stirring rod 31 is located at the lower part of the inner wall of the recovery box 19, and stirs at a speed of 150rpm / min~180rpm / mmin for 1.5min~2min, then controls the telescopic rod 30 to rise and adds a small amount of flocculant and stirs at a speed of 80rpm / min~100rpm / min for 2min~3min, then lowers the stirring rod 31 position and reduces the speed to 20rpm / min~30rpm / min and stirs for 10min~12min, and then stands for 10min~15min, reducing the use of flocculant. During equipment maintenance, the operator can dehydrate the flocculated sediment according to the soil remediation plan of the adjustment module in the storage chamber 3, and then mix it with straw and microbial agents to improve the saline-alkali land by composting; After the soil enters the storage chamber 3, the controller 2 controls the regulating motor 26 to drive the toggle rod 24 to toggle the soil entering the storage chamber 3, and evenly distributes the soil on the tray 25. The weight sensor 21 located under the tray 25 detects the weight of the soil on the tray 25. When the weight reaches 1kg to 5kg, the controller 2 controls the first output end of the three-way valve 10 to close, and opens the second output end of the three-way valve 10 to allow the remaining soil to enter the recycling box 19 through the recovery pipe 18. Subsequently, the controller 2 performs corresponding processing on the storage chambers 3 of different categories, and stores the storage chamber 3 of the first-class soil such as sandy soil, humus soil, peat and loose planting soil. The difficulty in repairing the first-class soil is poor water retention and easy migration of pollutants. Therefore, after the first-class soil enters the storage chamber 3, the controller 2 controls the first-class soil 3 to be cleaned. The controller 2 controls the switching nozzle 39 to switch, and sprays 8% to 10% of the decomposed organic fertilizer and the composite bacterial agent composed of Bacillus subtilis and actinomycetes in the regulating box 40 on the soil surface. The regulating motor 26 drives the toggle rod 24 to periodically move the soil. The storage chamber 3 for secondary soils such as moist clay, soft saline soil and building backfill soil containing gravel is stored. The difficulty in remediation is that the clay particles have strong ability to absorb pollution and salinization is easy to cause secondary pollution. The controller 2 controls the switching nozzle 39 to switch the connection with the regulating box 40, and sprays the 3% hydrogen peroxide and pH5-6 humic acid solution stored in the regulating box 40 on the soil surface for soil remediation. During the remediation process, the regulating motor 26 drives the toggle rod 24 to periodically move the soil. The medium-density clay, dry loess and In the storage chamber 3 for tertiary soils such as clay soil containing crushed stone and gravel, the difficulty in repair is the poor soil permeability and limited microbial activity. The controller 2 controls the switching nozzle 39 according to the weight of the soil to add the apatite stored in the regulating box 40 when the regulating motor 26 drives the toggle rod 24 to toggle the soil, and then sprays citric acid with a concentration of on the soil surface to promote the complexation and precipitation of heavy metal ions. During the repair process, the regulating motor 26 drives the toggle rod 24 to periodically to toggle the soil. In the storage chamber 3 for quaternary soils such as hard clay, medium-dense clay containing a large amount of crushed stone and gravel, and hard saline soil, the difficulty in repair is the high cost of mechanical crushing and the close combination of pollutants and gravel. Before the quaternary soil enters the storage chamber 3 through the three-way valve 10, the crushing valve located at the rear side of the outer currency of the storage chamber 3 for storing the quaternary soil is used. Unit 44 crushes the soil, and after completion, the soil enters the storage chamber 3. The controller 2 controls the switching nozzle 39 to spray the 10% cement-based curing agent stored in the adjustment box 40 on the soil surface. During the spraying process, the vibration unit 41 vibrates continuously, and the adjustment motor 26 drives the toggle rod 24 to periodically toggle the soil. At the same time, the connecting valve 8 is controlled to connect the drying box 12 and the storage chamber 3. The hot air generated by the hot air blower 17 is heated from the air outlet 42 through the connecting valve 8 to heat the inside of the storage chamber 3. The detection unit 13 installed on the rear side of the fill light 22 inside the storage chamber 3 detects the remediation status of the soil in the storage chamber 3, and records the relationship between the soil weight and the corresponding amount of remediation reagent added, which is convenient for subsequent large-scale remediation of the corresponding area of the soil.
