[0021] In order to facilitate the collection of debris generated during the drilling process, a dust hood 12 is provided on the above-mentioned base frame 1, and a discharge port is provided at the bottom of the dust hood 12. The discharge port is connected to the air inlet of the dust collecting device 14 through a dust exhaust pipe 13, and the exhaust port 14-2 of the dust collecting device 14 is connected to the inlet of the induced draft fan 16 through an exhaust pipe 15. The outlet of the induced draft fan 16 is connected to one end of the exhaust pipe 2 17, and the other end of the exhaust pipe 2 17 extends to a water tank 18 filled with clean water; the induced draft fan 16 is electrically connected to the controller 19.

[0022] The dust collecting device 14 comprises a box body 14-1, a partition 14-4 is arranged inside the box body 14-1, a cyclone separator 14-5 is arranged on the partition 14-4, an air inlet of the cyclone separator 14-5 is connected to the dust exhaust pipe 13, an exhaust port 14-2 is arranged on the top of the box body 14-1, the exhaust port 14-2 is connected to the exhaust pipe 15, and a slag discharge port 14-3 is arranged on the bottom of the box body 14-1.

[0025] The base plate 8 is provided with a plurality of guide rods 9 which slide through the top of the mounting frame 6 .

[0026] The specific working principle of the utility model is as follows: first, the steel pipe body 20 is placed on a pair of supporting rollers 3-4 of the clamping mechanism 3, then the telescopic end of the hydraulic cylinder 3-7 is started to extend, and the pressure rollers 3-9 of the pair of clamping mechanisms 3 are pressed on the steel pipe body 20, then the drilling motor 10 is started to control the telescopic end of the hydraulic cylinder 3-7 to extend, and the drill rod 11 starts to drill the steel pipe body 20.
