How many types of rock drills are there?

There are mainly two models, YN27C rock drills and YN27 rock drills. The hydraulic rock drill uses high-pressure oil as the power to drive the piston to impact the drill bit, with an independent rotary mechanism.

What is a pneumatic rock drill?

Pneumatic rock drills are suitable for various indoor operations, with simple operation, light weight, and less air consumption. Common models include handheld pneumatic rock drills such as Y6 and Y20. The electric rock drill is connected to the electric motor and hammer head through a crank connecting rod machine.

How does a drill bit penetrate a rock?

The particle speed variations occur very quickly at the bit tip, allowing the bit to penetrate the rock. For the percussive energy to be reliably transmitted to the bedrock, the bit must stay in contact with the rock, which happens by applying down pressure to the drill string.

How do you drill a hole in a rock?

For the percussive energy to be reliably transmitted to the bedrock, the bit must stay in contact with the rock, which happens by applying down pressure to the drill string. With both drilling methods, the cuttings are flushed up from the bottom of the hole with pressurized air or water.

What are the components of a water-well Rock Drill?

The water-well rock drill comprises many different and diverse components, including steel fabrications such as chassis, fuel tanks, mast, and gearboxes and bought-in components such as diesel engines, compressor, wheels, and bearings. (Plate 7.7)

What is a piston rock splitter?

Piston rock splitter is a new type of rock-breaking equipment. Its design is inspired by our common hydraulic jack. Using a piston rock splitter requires a larger hole diameter than a hand-held rock splitter (typically 90mm, 110mm, 130mm, 150mm, 180mm, or over 200mm). No vibration, no noise, and no flying stones during the working process.
