A scale 6 is installed on the sleeve 4. Through the position of the scale 6 and the upper surface of the cylindrical block 3, the distance between the sleeve 4 and the drill bit 1, that is, the subsequent distance that the drill bit 1 drills into the ground, can be obtained, which is convenient for the staff to sample the soil at different depths.

[0025] Embodiment 2:

[0026] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the adjusting member includes a polygonal block 15 at the end of the screw rod 14, and the screw rod 14 is slidably connected with the vertical hole 22, a round rod 23 is inserted into the vertical hole 22, and a polygonal groove 24 matching the polygonal block 15 is provided at the bottom of the round rod 23, and a limiting member for limiting the position of the sampling tube 9 is also provided in the cylindrical block 3. The round rod 23 is inserted into the vertical hole 22 until the polygonal groove 24 is sleeved on the polygonal block 15. By rotating the round rod 23, the screw rod 14 is rotated to change the position of the baffle 13 in the storage bin 11, so that the baffle 13 can close the storage bin 11 and prevent the soil sample in the storage bin 11 from falling out.

[0027] Embodiment three:

[0028] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the limiting member includes a slide groove 1 20 and a slide groove 21 provided in the cylindrical block 3, and the slide groove 1 20 and the slide groove 21 are respectively slidably connected to the slider 1 16 and the slider 2 17, and a spring 19 is fixed in the slide groove 1 20, and a through hole 18 is provided on the slider 1 16 and the slider 2 17, and the through hole 18 is slidably connected to the polygonal block 15.
