Abstract:
A cutter head has a front surface formed with several transmitting ports, a protection plate mounted at an external-end hole of each port, several microwave generating mechanisms distributed in two manners: first, the generating mechanisms are uniformly arranged in the cutter head; second, the microwave generating mechanisms in the same number as hobbing cutters. Each generating mechanism includes a microwave source, a magnetron, a rectangular waveguide, a circulator and a microwave focus radiator, wherein the microwave source is connected with the magnetron, the magnetron is connected with one end of the waveguide, the other end of the waveguide is connected with a first port of the circulator, a second port of the circulator is connected with the microwave focus radiator, and a water load is connected to a third port of the circulator. The focus radiator includes a standard waveguide section, an impedance matching section and a compressed radiation section.
