adapt to the action of the shifting plates, when the hydraulic rod 16 extends to the maximum length, the rotating column 13 drives the shifting plates 36 to rotate to the end part of the other side of the plate groove 37, at the moment, the rotating rings 34 are driven by the shifting plates 36 to rotate by one eighth of the radian, and then under the extrusion effect of the extruding blocks 33 on the bottom surfaces of the rotating rings 34, the dividing plates 29 in the circular cavity 28 are gathered towards the middle part, and because the dividing plates 29 are in a quarter cylinder structure, therefore, when the inner ends of the plurality of dividing plates 29 are closed, the collecting tank and the circular cavity 28 are divided into an upper part and a lower part, the soil corresponding to the positions of the dividing plates 29 is compacted into the soil on the upper side and the lower side under the extrusion of the dividing plates 29, so that the soil of the corresponding level is trapped in the collecting tank of the sampling rod 18 and the inner side of the inner ring 26 of the sampling rod 18, the staff can operate the motor 7 to reverse to lift the sampling assembly 17 out of the ground, and then the plurality of sampling rods 18 can be detached in sequence and the samples in the inner parts can be taken out and stored respectively, thereby not only achieving the effect of depth-fixed sampling, but also guaranteeing the integrity of the soil samples.
