Automated rock drilling operation Bright spot analysis:
1.To realize the change of excavator drilling machine, and in the same track above the multi-machine interchange (cutting drill, impact drill, drill),
to achieve a multi-purpose machine
2.The transformation of the excavator does not affect the original function of the excavator, no need to go to the second arm, more convenient
replacement (30 minutes can be restored to the excavator), convenient installation and disassembly, fast drilling speed, less energy
consumption
3.Add swing oil cylinder, so that when the excavator stops on different slopes, it can keep the drilling vertical.
