Features:
1. Supplied with air and cuttings discharge by an air compressor, various impactors and drill bits can be matched according to the size of the working hole.
2. Low failure rate, compact model, and high torque. The rotation speed can be adjusted according to different working conditions, effectively improving the efficiency of the impactor.
3. The hydraulic system is equipped with an independent hydraulic oil cooler, ensuring the drilling rig can work continuously in outdoor high-temperature conditions.
4. Displaceable sliding frame; during operation, the sliding frame can slide through the compensation oil cylinder to press against the ground working surface, improving the rigidity of the drill frame and ensuring the stability of the drilling rig.
5. Optional devices include reverse circulation device, mud pump, centrifugal pump, generator, and foam pump.
