DETAILED DESCRIPTION

The through end of the positioning wire 19 is threadedly connected to the rotating shaft 15 corresponding to the fixed block 18. A sampling tube 9 is connected to one end of the connecting block 14, and a push rod 13 is inserted into the end of the sampling tube 9 away from the connecting block 14. The sampling tube 9 is provided with a slide groove 10 corresponding to the push rod 13, and a slider 12 connected to the push rod 13 is slidably inserted into the slide groove 10. The other end of the connecting block 14 is connected to a rotating rod 16, and the end of the rotating rod 16 away from the connecting block 14 is connected to a rotating head 17. The positioning guide rod 23 is connected to the transmission rod 7, and the positioning guide rod 23 is slidably sleeved with a positioning sleeve 20.

[0031] How it works

[0032] When sampling soft soil, reverse the positioning wire 19 so that the positioning wire 19 is separated from the rotating shaft 15, and the rotating shaft 15 can rotate freely. The connecting block 14 is rotated so that the rotating rod 16 is set between the two groups of limit rods 8, and the positioning sleeve 20 is pulled down. The positioning sleeve 20 is sleeved on the rotating rod 16. At this time, the sampling tube 9 is convex and the axis of the sampling tube 9 is located on the same straight line as the axis of the transmission rod 7 and the transmission motor 5. The positioning wire 19 is rotated forward so that the positioning wire 19 is threadedly connected with the rotating shaft 15. At this time, the connecting block 14 cannot rotate, and the sampling tube 9 is positioned between the two groups of limit rods 8. The soft soil can be sampled through the sampling tube 9. After the sampling is completed, the slider 12 is pushed, and the slider 12 drives the push rod 13 to move outward. The push rod 13 can push the soil obtained by the sampling tube 9 into the sample preservation bottle during the outward movement. The slider 12 returns to its original position, and the sampling work can be completed once.

[0033] When sampling harder soil, the hole rotation work is performed first, and then the soil sampling work is performed. The soil sampling work is the same as the soft soil sampling. The hole rotation work is specifically as follows: reverse the positioning wire 19 to separate the positioning wire 19 from the rotating shaft 15, and the rotating shaft 15 can rotate freely, rotate the connecting block 14, so that the sampling tube 9 is set between the two groups of limit rods 8, and pull down the positioning sleeve 20. The positioning sleeve 20 is sleeved with the sampling tube 9. At this time, the rotating rod 16 is convex and the axis of the rotating rod 16 is aligned with the axis of the transmission rod 7 and the transmission motor 5. On the same straight line, the positioning wire 19 is rotated forward so that the positioning wire 19 is threadedly connected to the rotating shaft 15. At this time, the connecting block 14 cannot rotate, and the rotating rod 16 is positioned between the two sets of limit rods 8. The transmission motor 5 is connected to the mobile power supply 3 by controlling the switch 4. The transmission motor 5 rotates, and the transmission motor 5 drives the transmission rod 7 to rotate. The transmission rod 7 drives the rotating rod 16 to rotate, and the rotating rod 16 drives the rotating head 17 to rotate. When the bearing rod 1 is pushed, the rotating head 17 rotates the soil to make the soil at the rotating hole position soft.
