The invention has high precision and convenient operation, and does not require multiple sampling, thereby improving the sampling efficiency. A motor 10 for driving the sampling tube 6 to rotate is installed on the top of the support plate 4 and between the two hydraulic cylinders 3. The motor 10 is detachably connected to the sampling tube 6. When the hydraulic cylinder 3 drives the support plate 4 and the sampling tube 6 to descend and extend into the soil, the motor 10 drives the sampling tube 6 to rotate, so that the sampling tube 6 extends into the soil while rotating, thereby improving the sampling efficiency of the sampling tube 6. A mounting plate 11 is installed on the output shaft of the motor 10, and a connecting ring 12 is provided on the outer periphery of the sampling tube 6.

The soil in the sampling tube 6 can be easily taken out by disassembling it. A conical soil-breaking knife 14 is provided at the bottom of the sampling tube 6. The bottom ends of the partition 7 and the sealing plate 8 are located at the top of the soil-breaking knife 14 and are used to limit the positions of the partition 7 and the sealing plate 8.

A sample storage box 15 is provided on the top of the support platform 1. A plurality of sampling tubes 16 compatible with the sampling holes 9 are provided inside the sample storage box 15. After the sampling is completed, the plurality of sampling tubes 16 are taken out from the sample storage box 15, and then the sealing plate 8 is pulled out from the sampling tube 6.
