- Diesel engine and hydraulic pumps
- Control panel and joysticks
Working Principle
The Kaishan KT7D operates on a hydraulic top hammer drilling principle. A high-frequency hydraulic rock drill delivers impact energy, rotation, and feed force to the drill string. The piston strikes the shank adapter, transmitting shock waves through the drill rods to the bit, which crushes rock at the hole bottom. Simultaneously, the drill string rotates, indexing the bit for even wear. Flushing air or water removes cuttings from the hole, while the dust collection system captures airborne particles. The rig's hydraulic system controls boom positioning, feed pressure, and rotation speed, allowing precise adjustment to rock conditions. The operator monitors drilling parameters from the cabin, ensuring optimal performance and hole quality. This method is highly efficient for hard rock drilling, offering fast penetration rates and good hole straightness.
