[0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. When there are too many harmful substances in the soil, exceeding the self-purification capacity of the soil, it will cause changes in the composition, structure and function of the soil, inhibit the activity of microorganisms, and gradually accumulate harmful substances or their decomposition products in the soil, which are indirectly absorbed by the human body and reach a level that endangers human health.

[0060] How it works

[0061] S1: Positioning. The sampling vehicle 1 drives to the place where sampling is required and stops. The first crawler 201 and the second crawler 204 cooperate to raise the sampling component 2 and lower it to the upper end of the ground to locate the drilling position.

[0062] S2: drilling, the first motor 210 starts to drive the rotating head 213 to rotate through the telescopic mechanism 211 and the sampling column 212 to cooperate with the telescopic mechanism 211 to descend to drill holes in the ground, the sampling stabilizing plate 208 and the sampling fixing block 207 cooperate to fix the verticality, the sampling component 2 descends until the sampling column 212 is completely extended into the ground, and the first motor 210 stops rotating.

[0063] S3: Detecting the pH value of the soil. The sliders 216 in four levels and four directions in the detection group 214 in the sampling column 212 are pushed out by the first spring 217, and the detection rod 218 is pushed out by the second spring 219 to detect the pH value of the soil. The data is transmitted to the electronic device 302 for observation and analysis by the staff.

[0064] S4: Multi-layer and multi-directional sampling. The multiple slide-out blocks 220 in four levels and four directions in the sampling group 215 in the sampling column 212 slide out and insert into the soil multiple times. The rotating shaft 222 drives the rotating plate 221 to rotate to first scrape off the surface soil, and then the sampling slider 223 extends to cooperate with the rotating plate 221 to rotate to push the soil into the storage chamber 224. Finally, the pushing plate 225 and the third spring 226 in the storage chamber 224 cooperate to measure the required amount. When the sampling slider 223 retracts, the rotating plate 221 rotates to a vertical state, and the multiple slide-out blocks 220 slide back into the sampling column 212.

[0065] S5: Storage sampling, the telescopic mechanism 211 vertically moves the sampling column 212 out of the soil, the first motor 210 starts to clean the soil on the surface of the sampling component 2 by rotation, the first motor 210 is turned off, and then the first crawler 201 and the second crawler 204 cooperate to align the multiple sliding blocks 220 in one direction of the sampling group 215 at the top of the sampling column 212 with the telescopic tube 306, the telescopic tube 306 cooperates with the telescopic sleeve 305 to extend, and the multiple sliding blocks 220 slide out to the clean cloth belt 307 in the telescopic tube 306, and the second motor 317 starts to rotate through the linkage shaft The rotating disk 318 drives the rotating disk 316 to rotate and rotate the storage cup 319 to the bottom of the telescopic tube 306. The rotating plate 221 rotates and opens. The two third springs 226 push the two push plates 225 to push the soil to the middle and drop it into the storage cup 319. After the drop is completed, the rotating plate 221 closes and the multi-slide block 220 slides back. The contaminated cloth belt in the telescopic tube 306 slides into the telescopic sleeve 305. The contaminated cloth belt 308 in the cleaning chamber 313 is cleaned by the cleaning water chamber 309 through the spray pipe 311. The sewage enters the sewage chamber 310 through the sewage pipe 312. The cleaned contaminated cloth belt 308 8 Drying and disinfection are performed in the drying chamber 315 by the heating block 314, the clean cloth belt in the telescopic sleeve 305 slides into the telescopic tube 306, the first motor 210 starts to rotate in one direction, the second motor 317 starts to rotate the turntable 316 to rotate the next clean storage cup 319 to the bottom of the telescopic tube 306, the storage cup 319 storing the soil is rotated between the two first clamping plates 324, the two first clamping plates 324 slide up and down on the first rotating column 321 through the first rotating plate 322 to cover the storage cover 325 to the storage cup 319, and then the storage cup 319 is clamped and rotated to the second rotating plate 322. The soil is transmitted to the storage box 333 via a conveying mechanism 331, and the multiple sliding blocks 220 slide out to carry out soil falling in the second direction, and the soil is sequentially dropped and stored in four different directions at different depth levels. The storage cup 319 enters the storage box 333 through the guide plate 337, and the slide bar 334 pushes the storage cup 319 between two push rods 336, in a group of four directions at one level. When there are four storage cups 319 between the two push rods 336, the slide plate 335 slides to push the four storage cups 319 to the side and arrange them, and then the position, depth and orientation information is recorded through the electronic device 302.

[0066] S6: Clean the sampling component, and the soil storage is completed. The first crawler 201 and the second crawler 204 cooperate to stand the sampling component 2 upright. The water filling valve 230 is connected to a water pipe. Water enters each storage chamber 224 through the water inlet valve 228 for cleaning. The lower end is cleaned first and then moved upwards to avoid contamination of the lower part by the cleaning solution above. The pH value is then tested by the detection group 214 at the lower end of each sampling group 215 to determine the degree of cleaning. When the pH value is neutral, it means that the cleaning is complete. Stop cleaning and test and clean upwards in sequence.

[0067] S7: Find the pollution source. Find the pollution source according to the detection difference of pH value in four directions at four depths in the detection group 214. Then approach the pollution source step by step through multiple sampling and detection until the pollution source is found. Multiple detection and sampling are carried out to understand the pollution problem.
