What is a pneumatic rock drill
A pneumatic rock drill is a rock drilling equipment that uses compressed air as a power source and is widely used in mining, tunnel construction, building demolition and other fields. It has the characteristics of simple structure, convenient operation and strong adaptability, and is one of the indispensable tools in modern engineering operations. This article will introduce in detail the working principle, main components, application scenarios of pneumatic rock drilling machines, as well as popular topics and hot content in the past 10 days.
1. Working principle of pneumatic rock drilling machine
The pneumatic rock drill drives the piston to reciprocate through compressed air, thereby generating high-frequency impact force, transmitting energy to the rock drill rod, and achieving crushing of the rock. Its working principle can be summarized into the following steps:
1. Compressed air enters the cylinder through the intake valve, pushing the piston forward.
2. The piston hits the drill rod and transmits the impact force to the rock.
3. When the piston returns, the exhaust valve opens to discharge the exhaust gas.
4. Repeat and realize continuous rock drilling operations.
