[0027] Referring toFigure 3 , in order to complete the synchronous drilling and sampling, the drill pipe 32 is detachably connected to the driving base 31. The inside of the drill pipe 32 is a hollow structure. The upper part of the drill pipe 32 is provided with a first I-shaped groove 321 and a second I-shaped groove 322. A hidden partition plate 323 is rotatably connected to the lower part of the drill pipe 32. The hidden partition plate 323 is fixedly connected to the bottom end of the first lifting rod 324. The top end of the first lifting rod 324 is placed inside the first I-shaped groove 321; a collecting plate 326 is arranged below the hidden partition plate 323. The collecting plate 326 is fixedly connected to the bottom end of the second lifting rod 325. The top end of the second lifting rod 325 is placed inside the second I-shaped groove 322.

[0028] Referring to Figure 3 and Figure 6 , in order to facilitate the staff to understand the drilling depth of the drill pipe, a hydraulic rod 33 is further arranged at the bottom of the driving base 31, and a scale 331 is arranged on one side of the hydraulic rod 33.
