KJ321 Hydraulic Tunneling Rock Drilling Machine from China Suppliers and Factory for Efficient Tunnel Construction
Product introduction
Hydraulic Tunneling Rock Drilling Machine is a drilling equipment specially designed for tunnels and underground projects, which combines the efficient power of the hydraulic system with the professional technology of rock drilling. It is widely used in tunnel excavation, underground mining, subway construction, water conservancy projects and other fields.
1. Hydraulic system
Provides the main power of the drilling rig, including hydraulic pumps, hydraulic motors and hydraulic cylinders. The performance of the hydraulic system directly affects the efficiency and stability of the drilling rig.
2. Drill bit
Used to break rocks, select the appropriate drill bit according to geological conditions.
4. Working principle of hydraulic tunnel rock drilling rig.
5. Hydraulic tunnel rock drilling rigs use a hydraulic system to drive drill pipes and drill bits to perform drilling operations. The hydraulic system provides powerful power, allowing the drill bit to drill efficiently in hard rock formations. Drilling rigs are usually equipped with a variety of drill bits and drill pipes to adapt to different geological conditions and drilling needs.
