Slowly move the cross bar 18 downward, and the sliding blocks 20 on both sides provide stability for the cross bar 18 and its related components to avoid deviation. After the drill shaft 10 drills deep, the motor 2 17 is used to reverse the drill shaft 10. At this time, the spiral blade 11 rotates accordingly to gradually transport the external soil upward. The collected soil will pass through the collecting cylinder 6. The collecting cylinder 6 can protect the soil transported by the spiral blade 11 to prevent it from falling before entering the aggregate box 5. In the process of the drill shaft 10 rotating with the spiral blade 11 to transport the soil to the aggregate box 5, the dust cleaning brush 21 on one side of the inner wall of the aggregate box 5 will sweep some soil attached to the drill shaft 10 and the outer wall of the spiral blade 11 into the aggregate box 5 to avoid it being left in the spiral blade 11 and affecting the sampling results of the next use. Then the soil is swept out and collected through the front end outlet of the aggregate box 5.
