1、 Purpose, scope of use, and model meaning:

YT28Air leg rock drill is a type of rock drilling machine. It is applied in mining roadway excavation and various rock drilling operations to drill and drill blasting holes. It is an indispensable and important tool in metallurgy, coal rock, railway, transportation, water conservancy construction, and stone engineering.

YT28The use range of the type rock drill is wide, suitable for drilling horizontal and inclined blast holes on medium hard or hard (f=8-18) rocks. It can also drill anchor holes on the roof vertically upwards. The diameter of the blast hole is generally 34-42 millimeters, and the effective and economical drilling depth can reach 5 meters. This machine can be used in conjunction with the FT160BD short air leg and FT160BC long air leg according to the size of the tunnel section. It can also be installed on a drilling truck or drilling frame to work.

3、 Working principle

YT28A rock drill uses compressed air to push the piston back and forth. During the stroke, the piston impacts the drill tool to break rocks: during the return stroke, the piston drives the drill tool to rotate at a certain angle. Continuous impact and rotation cause the drill tool to cut circular holes in the rock.

IVPiston stroke:

As shown in Figure 1, when the control lever (32) is placed in the operating position, compressed air enters the rear chamber of the cylinder block (6) from A: pushing the piston (5) forward. When the trailing edge of the piston V2: opens the push valve hole T2, a portion of the compressed air enters the valve cabinet (2) through T2, and the push valve (10) reverses direction, closing the stroke air circuit A (while opening the return air circuit B). At this time, the piston works by inertia and pressure expansion, continuing to forward, striking the drill tail, and completing the stroke movement.
