spiral drilling machine is a kind of spiral blade drilling machine,include drilling machine framework,slide rail on the framework,with reduction gearbox could slide up and down on the solide rail.reduction gearbox connected with power input axle and power output axle,another end of the power input axle connected with hydraulic motor,another end of the power output axle connected with drill stem,broach under the drill stem.

pulley on the cylinder rod of hydraulic cylinder drive the reduction gearbox slide up and down equipment,the two end of the wire rope which around the pulley fixed with the reduction gearbox.
drill stem is spiral blade drill stem

power output axle is hollow spindle
spiral drilling machine can improve the working performance. drive equipment drive the reduction gearbox to realize the up and down movement of the drill stem.more conducive to drilling faster and powerful.reduction gearbox can slide up and down on the slide rail of the drilling machine framework,to ensure the verticality of the borehole.drill stem is spiral blade drill stem,it can transport soil back to the ground when drilling.power output axle is hollow spindle,the up end of the spindle can be connected with cement perfusion equipment,to perfuse cement

suit for:drilling borehole work of planting,telecom,electric power,municipal garden,road,railway etc
