Simple hard rock TBM

The invention provides a simple hard rock TBM. The simple hard rock TBM comprises a stabilizer assembly, the stabilizer assembly is provided with a swing type cutter assembly, the swing type cutter assembly is connected with a sliding beam assembly, the sliding beam assembly is internally provided with a deslagging device assembly, the stabilizer assembly is connected with a propulsion supportingsystem, and the sliding beam assembly slidably cooperates with the propulsion supporting system. The simple hard rock TBM has the advantages that a hard rock is broken creatively by adopting a swing type cutter, the structure is simple, and a main bearing, a main driving motor or motor and other series of parts which are difficult in maintenance and higher in cost are not needed; the structure ofa cutter can be changed, thereby capable of excavating various fracture surface shapes, such as a rectangle, a fracture surface with arches on the upper and lower portions; in addition, according to the engineering needs, the
