First of all, let's talk about down-the-hole drilling 1. The down-the-hole drilling machine uses a motor as a rotary power through a high-performance reducer; it uses a cylinder as a propulsion power. The hydraulic system is omitted, so the mechanical efficiency is high, the cost is low, and the performance is stable.
2. With anti-jamming protection, when the drilling tool is stuck, the motor is not easy to be burned, and the reducer is not easy to be damaged.
3. It is light and easy to move. The weight of the whole down-the-hole drilling rig is less than 500Kg, and it can be broken down into three pieces, which is convenient for moving and putting on shelves.
4. The rolling carriage is adopted, and the track is not easy to wear.
5. The down-the-hole drilling rig adopts semi-automatic dismantling of drill pipes, which has high working efficiency.
