The invention discloses a wheel drilling machine which comprises a wheel traveling mechanism, a drilling rod assembly, a drilling machine loading mechanism and a hydraulic control mechanism. The hydraulic control mechanism comprises an oil pump and a multi-path control valve. The wheel traveling mechanism is arranged in hinged mode, and accordingly a drilling rod can perform positioning and drilling fast and accurately. A diesel engine supplies power to the wheel drilling machine, and the wheel drilling machine is self-propelled. Hydraulic oil reaches the multi-path control valve through a gear pump, and the multi-path control valve can carry out six groups of movements, namely vertical lifting, supporting legs, back-and-forth inclining, left-and-right moving, drilling and core pushing. The wheel drilling machine solves the problems that the existing drilling machine is inflexible in angle adjusting, inaccurate in positioning and much in manpower consumption.
