description The invention relates to an excavating drilling machine comprising a base, an upper lathe, a mast, a drill rod and a drill head, wherein the upper lathe is provided with a hydraulic system and an electronic control system; and the drill head comprises a straight hole drill head and a bottom-expanding drill head, wherein the straight hole drill head and the bottom-expanding drill head are respectively arranged on the drill rod in an alternating way. The excavating drilling machine can simultaneously realize the straight hole drilling operation and the bottom-expanding bottom-expanded operation, that is to say, can implement the diameter-expanding excavation on the lower part of a foundation after a straight hole is drilled to a certain depth and automatically fetch the soil; and in addition, the invention can sufficiently meet the requirements for mechanized construction of the excavating foundation of an electric transmission line.
