After the soil sample enters the sampling tube 4, the user reinserts the bolt 16, inserts the bolt into the positioning hole 17 for controlling the opening state of the bending piece 6, and fixes the inner rod 3 which slides up to a certain height;
then, the user continuously presses the guide cylinder 1 to enable the cone head 2 to be further inserted into soil, and at the moment, the soil can enter the sampling cylinder 4 in an opened state through the hollow-out parts 9 around the cone head 2;
when the predetermined sampling amount or depth is reached, the user again operates the plug 16, pulls out the plug 16 from the positioning hole 17 for controlling the opening state of the bending piece 6, presses down the inner rod 3, inserts the plug 16 into the other positioning hole 17 for controlling the closing state of the bending piece 6, and the bending piece 6 is extruded by the framework of the cone head 2, and bends and adheres to each other to form a closed hollow cone, so that the soil sample can be ensured to be completely collected in the sampling cylinder 4 in the sampling process, and the sample leakage is avoided;
After the sampling is completed, the user pulls out the guide cylinder 1, removes the top cover 7, and then takes out the inner rod 3 and the sampling cylinder 4 from the guide cylinder 1, at this time, the inside of the sampling cylinder 4 contains soil samples of the required soil layer for subsequent analysis.
