[0032] Execute the working principle of the present invention: move this embodiment to the target sampling point, first transfer the drilling piece, specifically, initially, the drilling piece is installed on one of the fixing pieces, that is, the fixing rod 9 is matched with the matching hole, and the electromagnetic support slide column 901 on the end of the fixing rod 9 is supported and positioned, so that the drilling piece is fixed; the motor 3 works to move the screw rod 5, and then the moving plate 4 moves, and the drilling piece is transferred to the front of the position where the moving piece is located, and the moving frame 11 is controlled to move by the moving oil cylinder 10, so that the matching fixing plate 17 is located at the position of the fixing hole on the matching fixing seat 31. Specifically, the fixed control electric cylinder 15 controls the push wheel 16 to move, and the push wheel 16 moves in the inclined groove on the matching fixing plate 17, so that the matching fixing plate 17 slides and matches with one of the fixing holes on the matching fixing seat 31 (the two fixing holes are arranged up and down, and the matching fixing plate 17 matches with the fixing hole located below), and the drilling piece is fixed. Afterwards, the lifting motor 12 works, the lifting screw rod 13 rotates, the lifting seat 14 slides, the lifting seat 14 drives the drilling piece to move downward, and the drilling motor 30 works to rotate the drilling shaft 28, thereby completing the first stage of drilling operation.
