Function of rock drills
A rock drill is a tool used to directly mine stone. It drills holes in the rock formation so that explosives can be put in to blast the rock to complete mining of stone or other stone works. In addition, the rock drill can also be converted into a breaker to break hard layers such as concrete.

Classification of rock drills
Rock drills can be divided into four categories according to their power sources: pneumatic rock drills, internal combustion rock drills, electric rock drills and hydraulic rock drills
Working principle of pneumatic rock drills
The pneumatic type uses compressed air to drive the piston forward in the cylinder, causing the steel drill to strike the rock. It is the most widely used. Electric type
The electric motor drives the hammer head through the crank connecting rod mechanism to impact the steel drill and chisel the rock. And the powder discharge mechanism is used to discharge stone chips. The internal combustion type uses the principle of the internal combustion engine to drive the piston to impact the steel drill and chisel the rock through the explosive force of gasoline. Suitable for construction sites without power supply or air source. The hydraulic type relies on hydraulic pressure to impact the steel drill through inert gas and the impact body to chisel the rock. When the impact mechanism of these rock drills returns, the drill bit rotation mechanism forces the drill bit to rotate, causing the drill head to change its position and continue drilling the rock. The blasting force of the diesel fuel drives the piston to impact the steel drill, which continuously impacts and rotates, and the powder discharge mechanism is used to discharge the stone chips to create a blast hole.
The working principle of the internal combustion rock drill
The internal combustion rock drill does not need to replace the internal parts of the machine head. It only needs to move the handle as required to operate. It is easy to operate, saves time and effort, has the characteristics of fast cutting speed and high efficiency. Drilling holes in the rock can be done vertically downward and horizontally upward, and the deepest drilling can be up to six meters vertically downward. This machine can work in high mountains, flat areas, in extremely hot or sub-zero cold areas. This machine has wide adaptability.
The internal combustion rock drill has the functions of splitting, crushing, tamping, shoveling, etc. in mining, construction, cement pavement, asphalt pavement, etc. It is widely used in mining, construction, firefighting, geological exploration, and road construction. , quarrying, construction, national defense engineering, etc.
