Down-the-hole drilling rig is currently a commonly used type of electric rock drill, and the drill rod is ordinary round drill rod or twist drill rod. DTH drilling rig composition: Propulsion structure: motor reducer, outrigger, support, sliding frame Drilling tool structure: impactor, drill bit, drill rod, operating structure: control valve, control frame, electrical components, barometer, fog holder. The down-the-hole drilling rig eliminates the need for hydraulics, so it has high mechanical efficiency, low cost and performance. Down-the-hole drilling rig is suitable for underground mine tunneling, mine tunneling, mining, water conservancy construction, road construction and stonework operations. It has the characteristics of reasonable structure, convenience, easy operation, and reliability.
Down-the-hole drilling rig
1. The down-the-hole drilling rig uses a motor through a high-performance reducer as the rotation power; a cylinder is used as the propulsion power. The hydraulic system is omitted, so the mechanical efficiency is high, the cost is low, and the performance is stable.
2. The down-the-hole drilling rig has anti-jamming protection. When the drilling tool is jammed, the motor is not easy to burn and the reducer is not easy to damage.
3. It is light and easy to move. The weight of the down-the-hole drilling rig is less than 500Kg, and it can be broken down into three pieces, making it easy to move and mount the machine.
4. The down-the-hole drilling rig adopts rolling carriage, and the track is not easy to wear.
5. The down-the-hole drilling rig adopts semi-automatic disassembly of drill rods, which has high working efficiency.
