In the initial state, the separation disc 31 is at the lower limit position, and at this time, the pressing seat 35 presses the annular sealing plate 21 into the mounting groove 22 through the pressing block 24. Meanwhile, the reaction force provided by the annular sealing plate 21 also enables the limiting insert 36 to be completely retracted into the pressing seat 35, and at this time, the top of the limiting insert 36 is abutted against one end of the rotating plate 332 away from the sealing circular plate 331, so that each sealing circular plate 331 is completely clamped in the step hole 32 and cannot rotate, and therefore, soil entering the sampling tube 1 cannot enter the upper portion of the separation circular plate 31 through the step hole 32.

In use, the drive module 5 is connected to the top of the sampling cartridge 1, and then the drive module 5 is activated and the sampling cartridge 1 is inserted into the ground at the designated location. The driving module 5 can drive the sampling tube 1 to synchronously rotate, and the soil can be rotationally excavated through the rotary excavating teeth 13 at the bottom of the sampling tube 1, so that the sampling tube 1 is continuously penetrated into the ground, and in the process, the soil entering the sampling tube 1 can be discharged to the outside of the sampling tube 1 through the soil discharge hole 14.

As the amount of soil entering above the divider disk 31 increases and the divider disk 31 moves upward, the divider disk 31 compresses the soil between the divider disk 31 and the filter plate 41 (the reaction force of the soil in this region on the seal disk 331 will cause the seal disk 331 to re-engage the stepped hole 32, and the combination of the divider disk 31 and the adjustable seal plate 33 can be considered as a platen), and after the soil is compressed, the soil solution contained therein will be filtered through the filter plate 41 and then compressed above the filter plate 41. In this process, the separation circular plate 31 will abut against the adjusting unit, specifically, the separation circular plate 31 will abut against the bottom of the push rod 43, and as the separation circular plate 31 continues to move upwards, the separation circular plate 31 can drive the push rod 43 to move upwards synchronously, and the push rod 43 can drive the piston plate 44 to move upwards synchronously, so that a negative pressure is formed in the sampling piston cylinder 42, and then the soil solution filtered by the filter plate 41 can be sucked into the sampling piston cylinder 42 through the liquid suction pipe 45, so as to realize sampling of the soil solution.
