The working principle of the invention is as follows: when the device is used, a corresponding number of sampling devices 24 are selected according to the number to be sampled, then the probe 21, the first sampling device 24, the lengthening tube 22, the second sampling device 24 and the connecting tube 23 are sequentially installed from bottom to top through threads, the length of the limiting block 2415 on the sampling device 24 close to the probe 21 is greater than that of the limiting block 2415 on the sampling device 24 far away from the probe 21, wherein the length of the lengthening tube 22 is selected according to a preset distance between the two sampling devices 24, then the rotating shaft 26 is inserted into the cylinder 212, then the corresponding transmission device 243 is sleeved on the transmission rod 25 (the transmission rod 25 is a rectangular telescopic rod), when the transmission device 243 is installed, the height limiting block 2433 with a short length is sleeved on the transmission rod 25, the height limiting block 2433 with a long length is sleeved on the transmission rod 25, so that the height limiting block 2433 with a short length can directly slide downwards to the lowest end without contacting with the sampling device 24 far away from the probe 21, the rectangular height limiting block 2433 can be embedded into the clamping groove 2416 on the corresponding limiting block 2415, and then the connecting tube 23 is inserted into the connecting plate 16, and the lower end of the connecting plate 18 is installed;
when the device is used, the hydraulic cylinder 15 is started, the hydraulic cylinder 15 is stretched to drive the connecting plate 16 and further drive the L-shaped plate 233 to move downwards, the L-shaped plate 233 drives the connecting pipe 23, the lengthening pipe 22, the sampling devices 24 and the probe 21 to move downwards, after the probe 21 moves downwards to a preset depth, the sampling device 24 close to the probe 21 also reaches the preset depth, because the length of the lengthening pipe 22 between the two sampling devices 24 is set according to the required interval distance of the two sampling devices 24, the sampling device 24 far away from the probe 21 also reaches the preset depth, then the motor 17 is started, the motor 17 drives the connecting piece 18 to rotate, further drives the transmission rod 25 to rotate, the transmission rod 25 drives the elliptical transmission block 2431 on the transmission device 243 to rotate, when the elliptical transmission block 2431 rotates, when the two end points of the elliptic driving block 2431 which are farthest away are respectively contacted with the storage barrel 2421, the storage barrel 2421 is pushed to move in the direction away from the driving device 243, and the storage barrel 2421 also drives the baffle 2425 to move, so that the storage barrel 2421 is exposed out of the outer end of the sampling device 24 from the opening 2412, soil slides into the storage barrel 2421 from the slideway I2422 at the upper end of the storage barrel 2421, and because the T-shaped slide block 2424 and the slide block 2427 are fixedly connected to the connection ring 2414, the spring 2428 is compressed when the storage barrel 2421 moves, and when the two opposite end points of the elliptic driving block 2431 which are closest to each other are respectively contacted with the storage barrel 2421, the storage barrel 2421 moves into the shell 2411 again under the elastic force of the spring 2428, and the operation is circulated, so that the storage barrel 2421 collects enough soil; when the storage barrel 2421 moves towards the inside of the shell 2411, the T-shaped sliding block 2424 slides in the slide way I2422 and the slide way II 2423 and pushes away soil in the slide way I2422 and the slide way II 2423, so that the condition that the slide way I2422 is blocked by soil accumulation and subsequent soil enters the storage barrel 2421 is avoided; after the soil sampling is finished, the hydraulic cylinder 15 is contracted, the sampling device 24 is taken out, and then the soil can be respectively collected after disassembly, so that the soil sample can be prevented from being mixed with other samples, and the detection result is inaccurate;
when different depths are to be measured, the depth of the plurality of sampling devices 24 and the distance between the plurality of sampling devices 24 may be adjusted by the length of the elongated tube 22.
