The rock drilling machine uses the rotation of the ratchet to make the drill rod rotate on the rock to impact the rock, the impact piston moves up and down, the discharged gas enters the center hole of the drill rod, and blows the powder impacting the rock out of the hole. According to the needs of 28-40mm carbide drill bits, according to the different hardness of the rock, the alloy drill bits with different hardness are equipped. According to the required size of the hole, replace the alloy drill bits of different sizes, which are suitable for drilling and blasting in various mines.
Internal combustion gasoline rock drills are also called internal combustion rock drills. Because its gasoline engine is small in size and easy to carry, the overall drilling machine weighs only more than 20 kilograms, and does not need to be equipped with any auxiliary equipment, just install the drill rod, and the drill bit can work. Therefore, it is suitable for mines with no wind power, no power supply, and less developed traffic. Drill holes in the rock, and the deepest hole can be up to six meters vertically downwards and horizontally upwards less than 45°. The machine is easy to operate, saves time and effort, and has the characteristics of fast chisel speed and high efficiency. No matter in high mountains, flat land, no matter in 40 ° hot or minus 40 ° cold area, it can work, this machine has a wide range of adaptability.
The rock drilling machines are widely used in mining, road construction, quarrying, fire protection, geological exploration, national defense engineering, etc.
