The invention provides a cutterhead structure provided with rotating knife beams. The cutterhead structure provided with the rotating knife beams comprises main beams arranged between a sleeve and anouter ring beam, wherein each main beam comprises a rotation section and a fixed section, two ends of the rotation section re movably arranged at the fixed section, and a cutter is arranged at the rotation section. The cutterhead structure has the following advantages: the excavation cutters are arranged at the rotation sections which are axially mounted on the main beams, rotation of the excavation cutters is driven by rotation of the rotation sections to realize excavation of soil mass of a tunnel face, the problem of larger linear velocity difference of the cutters of the conventional cutterhead is solved, and the tunneling efficiency of the cutterhead is increased.
