The invention discloses an adaptive excavating integrated machine. The adaptive excavating integrated machine comprises a gantry assembly installed on a complete machine underbed, a fixing platform installed on the complete machine underbed, a working mechanism for providing operation, a drill machine supporting mechanism, a conveying mechanism for conveying materials, a laser device, a walking mechanism installed below the underbed and switched between crawler-type walking and wheel-type walking, a hydraulic mechanism, a driving mechanism for providing power for the complete machine and a cab assembly. The working mechanism comprises an excavating working arm mechanism installed at the front end of the gantry assembly and a cutting working arm mechanism installed above the gantry assembly, and the excavating working arm mechanism and the cutting working arm mechanism can be switched for working; the laser device assists the cutting working arm mechanism in rock crushing, and the drill machine supporting mechanism drills anchor rope supporting holes in the top of a roadway. By means of the technical scheme, multiple walking, crushing, cutting, excavating, loading and supporting functions are achieved, continuous excavating, loading and conveying work is achieved, applicability is high, the integrated machine is multipurpose, acquisition cost is saved, the number of operation process workers is reduced, working efficiency is improved, engineering quality is improved, and working safety is ensured.
