The YX-421TA/421H integrated open-air down -the-hole drilling rig is an advanced drilling equipment that integrates the down-the-hole drilling system and the screw air compression system. It is equipped with a Yuchai six-cylinder national three diesel engine to provide power for the two systems. It has a compact structure and good integrity. , Easy to move.

High-pressure single-stage compression screw with core drill rig equipment product knowledge of the nose, the application of leading international Tom's Y -shaped line, turnover rate ( 13m³ / min ) , pressure high ( 1.7 MPa ), high wind pressure Pneumatic impactor provides strong power, and the rock drilling speed is 20%-50% higher than that of the air pressure drill rig .YX-421TA/421H integral high-pressure open-pit down-the-hole drilling rig is mainly used for rock work in stone works and open-pit mines.
