[0065] The first rotary motor 8 and the stepper motor 63 are activated by an external controller, and the stepper motor 63 drives the threaded rod 64 to rotate in the forward direction, causing the sliding plate 62 to move downward. This action causes the drive box 7 and the drill tube 11 to move downward, and the rotation of the first rotary motor 8 causes the U-shaped plate 9 to rotate, thereby driving the drill tube 11 to enter the soil for sampling.

At the same time, the second rotary motor 54 is started by an external controller to rotate, so that the drill rod 55 rotates, and the drill rod 55 rotates into the soil to fix the soil sampling equipment.

[0071] The operation of the first rotary motor 8 and the stepper motor 63 is controlled by an external controller. The stepper motor 63 rotates forward, driving the threaded rod 64 to rotate forward, so that the sliding plate 62 moves downward, driving the drive box 7 and the drill barrel 11 to move downward.

[0073] Then the insertion rod 12 is pulled out to the right, and the drill tube 11 is removed, so that the collecting tube 14 slides out upward, and the soil sampling is completed.

[0074] Soil is poured into the feeding frame net storage box 101, and the rotating motor 104 is turned on by an external controller to rotate the conveying rod 105, so that the soil enters the conveying pipe 103 through the channel pipe 102, and then moves to the left through the conveying rod 105 until it falls into the drill hole, so that the drill hole generated during sampling is filled.
