　　YT28Air leg rock drillWorking Principle:

　　YT28Air leg rock drillIt works according to the principle of impact fragmentation. During operation, the piston undergoes high-frequency reciprocating motion, continuously impacting the drill tail. Under the action of impact force, the wedge-shaped drill bit crushes the rock and chisels it into a certain depth, forming a dent. After the piston retracts, the drill bit rotates a certain angle, and the piston moves forward. When it impacts the drill tail again, a new indentation is formed. The fan-shaped rock block between the two indentations is sheared by the horizontal force generated on the drill bit. The piston continuously impacts the tail of the drill and continuously inputs compressed air or pressure water from the drill to discharge the rock debris out of the hole, forming a circular borehole of a certain depth. Rock drills can be classified into four types based on their power sources: pneumatic rock drills, internal combustion rock drills, electric rock drills, and hydraulic rock drills. Before rock drilling, check the integrity and rotation of all components (including rock drills, supports, or rock drilling trolleys), add necessary lubricating oil, check whether the air and water paths are unobstructed, and whether all connecting joints are secure.

　　YT28Air leg rock drillOperating procedures:

　　1. Knock on the top of the gang around the incident area, that is, check the top plate and the second gang for any live stones or loose stones, and make necessary punishments.

　　2YT28 air leg rock drillBefore rock drilling, inspect the integrity and movement of all components (including rock drills, supports, or rock drilling trolleys), add the necessary smooth oil, check the air and dry roads, and ensure proper connections.

　　3. The drill staff should wear gloves when drilling. 4. It is strictly prohibited to dry the eyes. Wet rock drilling should be carried out. When operating, water should be boiled first and then the air should be turned on. When stopping drilling, the air should be turned off first and then the water should be turned off. When opening your eyes, run at low speed first, and wait until you reach a certain depth before drilling at the same speed.

　　5. The position of the flat borehole should be leveled before drilling to avoid slipping or displacement of the borehole.
