China Yt23D Air Leg Rock Drill for Hard Rock

YT23D Air Leg Rock Drill for Hard Rock
A kind of shock-drilling machine with compressed air as its driving force. According to the propulsion mode
is also divided into hand-held rock drilling machine, gas-leg rock drilling machine, telescopic up-type rock
drilling machine and guide-type rock drilling machine.
Introduction of YT23D Air Leg Rock Drill for Hard Rock 1. The YT23D Air Leg Rock Drill for Hard rock has good performance under low pressure; it is suitable for act
impetus with long air pipe and small air compressor.
2. And it is use for drilling in mines, quarries, railway construction, water conservancy and national defense project
facility.
3. When it is matched with Model FY200A oil reservoir and Model FT160A or FT160B air-leg, it can perform wet
drilling under various of rocks at a clinic and incline orientation, it can also use in the trolley without Air-leg.
4. Hand-hold rock drill is a tool for the secondary blasting in quarry and especially for rocking 20mm hose in marble
and granite, it has characteristic of low weight, reasonable structure, handy use and little air consumption.

Work principle
Rock drill work, the air pressure alternately changes into the cylinder's back cavity and the front cavity,
pushes the piston to return movement. The same pressure also acts on the rear cover or front cover of the cylinder,
which causes the rock drill to retreat or advance, so that the rock-drilling machine produces vibration to produce a
hammering force.
