The suction hood 74 is arranged at the lower end of the drill frame 3, and the drill rod assembly 4 comprises a drill rod 41, and the drill rod 41 passes through the suction hood 74. The pulse dust collector 71 is adopted for dust collection, the dust collection effect is good, and the problems that the continuous operation time is short and the construction progress is influenced due to the fact that the water is adopted for dust collection of a drilling machine in the past are solved.
As a further improvement of the above, the dust removing device 7 further includes a cyclone 75 provided at a lower end of the drill frame 3, and the cyclone 75 communicates the pulse dust collector 71 with the dust hood 74.
