With formerly was common the drilling machine to compare, this design 300 meters dived the water well drilling machine to use the marching hydraulic pressure actuation undercarriage system, the motion are more flexible, could adapt and so on moistly the adverse circumstance. The power head main body structure also did modified greatly, lengthens the main axle service life, the power head has used the whole fluctuation structural style, when picked up and unload the drill rod the effective protection attachment thread, reduced the drill rod damage. This article studies mainly is the power head part design. The power head part also is the entire drilling machine most important part, but the gear and the main axle design relates the entire power head the service condition, therefore in the article the counter gear and the main axle have carried on the detailed examination computation, the main axle terminal seal also are a this design key point, mainly manifests in from in the tight seal packing collar design. The box body uses the steel plate welding manner to make, in satisfies the operation requirements under the premise, but also reduced the production cost.
