Summary:The utility model discloses a heading machine for breaking rocks by utilizing laser, which solves the problems that the shield tunneling efficiency is reduced, the tunneling cost is increased and thelike along with the increase of rock strength, abnormal abrasion of a hob and the increase of replacement frequency. The tunnel boring machine comprises a tunnel boring machine main machine, a cutterhead is arranged on the tunnel boring machine main machine, and a laser generating device is arranged on the cutter head. According to the utility model, the traditional metal cutter is replaced by laser and water cooling principles; compared with the prior art, the rock breaking efficiency is greatly improved, the problem that a traditional metal cutter is extremely prone to abnormal damage is solved when the geology with the soft upper portion, the hard lower portion and the like is tunneled, the cutter cost is saved, the cutter replacement risk is reduced, the mode of suspension cutting rock breaking or extrusion ro
