[0020] A drill bit is installed at the bottom of the drill rod 6, and the motor 1 7 drives the drill rod 6 to rotate so as to drill downward. The motor 2 11 drives the screw rod 14 to rotate so as to prompt the drive seat 9 to drive the mounting frame 5 to move downward, and cooperate with the drilling of the drill rod 6 to make the drill rod 6 penetrate into the ground. The mounting frame 5 drives the pointer 16 to move to adjust the height of the pointer 16. When the drill bit touches the ground, the height value of the pointer 16 is recorded. When the drilling stops, the height value of the pointer 16 is recorded again. The difference between the two is the thickness of the soil layer.
