The electrical, hydraulic, operating and monitoring instruments of the whole machine are all concentrated in the cab, which is convenient for the driver to operate Rotary drilling rig is used to drill and form holes. Firstly, the drilling tool can be correctly positioned at the pile position through the drilling rig's own walking function and mast luffing mechanism, and the mast is used to guide the lower drill rod to have a valve at the bottom. The barrel type drill bit is placed in the hole position, the power head device of the drilling rig provides torque for the drill pipe, and the pressurizing device transmits the pressure to the drill pipe bit through the pressurizing power head. The bit rotates to break the rock and soil and directly install it. Enter the drill bit, and then lift the drill bit out of the hole by the drilling rig lifting device and the telescopic drill rod to unload the soil, so that the soil is cyclically taken and unloaded, and the straight drill meets the design depth. At present, the working principle of rotary drilling rigs is mostly in the form of connecting drill pipes and dregs digging buckets. In the drilling process, mud circulation is mostly used. The mud plays a role in lubricating, supporting, replacing and carrying slag for this kind of drilling rigs.Rotary Drilling Rig price website:http://www.xiangchimachinery.com/rig/rotary-drilling-rig/
