The limiter 13 prevents the drill rod 12 from deviating during the drilling process. The rotation of the drill rod 12 of the hydraulic down-the-hole drill 1 drives the rotation of the drill bit 14 to clean the concrete blocked in the mixed pump pipe 3. This device reduces the difficulty of clearing the pump pipe 3 blocked by high-grade concrete and increases the speed of clearing the pump pipe 3.

[0044] like Figure 1 and Figure 2 As shown, in some embodiments, the hydraulic down-the-hole drill 1 is installed on the guide rail 2 through a moving mechanism, and the moving mechanism includes a gear 51 arranged on the hydraulic down-the-hole drill 1 and a CNC motor 5 driving the gear 51.
