I. Working Principle of Rock Drill

A rock drill is a tool used for mining minerals or cutting stones in the construction industry. The inside of rock drill mainly includes motor, chisel head, chisel head chuck, rock drill body, lifting mechanism and other parts. The motor drives the chisel head in reciprocating motion to drill, cut and grind the stone.

Second, the difference between forward and reverse rotation

The motor of rock drill has two working modes: forward rotation and reverse rotation, but some rock drills only have forward rotation without reverse rotation.

Forward rotation: the motor rotates positively, the chisel head trajectory is upward, used for cutting soft rock.

Reverse rotation: the motor rotates in the reverse direction, the chisel head trajectory is down, used for drilling hard rock.

Choose the working mode of forward or reverse rotation.

The key to choosing the working mode of rock drill lies in the need to pay attention to the hardness of the rock. If it is hard rock, you should choose the reverse mode. If it is soft rock, you should choose positive rotation. The correct choice of rock drill working mode can effectively improve the efficiency and quality of work.

Summarise: The working mode of rock drill is just like the motor, which can be rotated positively and negatively. Choosing the right working mode can improve the working efficiency and quality of work.
