A second installation shell 804 is fixedly installed on the mounting frame 2. A second electric telescopic rod 805 is fixedly installed inside the second installation shell 804. The free end of the second electric telescopic rod 805 is fixedly connected to a first sliding plate 806. A toothed plate 807 is fixedly connected to the first sliding plate 806. A rotating shaft 808 is rotatably connected inside the second installation shell 804. A half gear 809 is fixedly installed on the outer surface of the rotating shaft 808. A connecting arm 810 is fixedly connected to the outer surface of the rotating shaft 808. The other end of the connecting arm 810 is fixedly connected to a high-pressure nozzle 811. By opening a first through hole at the center of the support base 1, a second through hole is opened on each adjacent side of the two installation cavities 801. The second through hole is communicated with the first through hole. A sliding hole is opened on each adjacent side of the two second installation shells 804. The connecting arm 810 extends to the outside of the second installation shell 804 through the sliding hole. The rotating shaft 808 is rotatably connected to the second installation shell 804 through a bearing. When the free end of the first electric telescopic rod 802 extends, the cleaning brush 803 is driven into contact with the outer surface of the drill bit 7. Then, with the cooperation of the motor 5, the drill bit 7 is driven to rotate, so that the cleaning brush 803 can preliminarily clean the mud and rock debris adhered to the outer surface of the drill bit 7. Since the high-pressure nozzle 810 is connected to an external water delivery pipe, the spraying direction of the high-pressure nozzle 810 can be adjusted at an angle under the cooperation of the second electric telescopic rod 805, the toothed plate 807, the rotating shaft 808, the half gear 809 and the connecting arm 810, realizing more comprehensive cleaning of the drill bit 811.

At the same time, start the motor 5 to drive the drill bit 7 to rotate, so that drilling exploration can be carried out. When it is necessary to clean the drill bit 7, start the first electric telescopic rod 802, and make its free end extend to drive the cleaning brush 803 to contact the outer surface of the drill bit 7. Then, with the cooperation of the motor 5, drive the drill bit 7 to rotate, so that the cleaning brush 803 can preliminarily clean the mud and rock debris adhering to the outer surface of the drill bit 7. Finally, connect the high-pressure nozzle 810 to an external water delivery pipe. Then, with the cooperation of the second electric telescopic rod 805, the toothed plate 807, the rotating shaft 808, the half gear 809 and the connecting arm 810, adjust the spraying direction of the high-pressure nozzle 810 to achieve a more comprehensive cleaning of the drill bit 811.
