PURPOSE: A cutter-linked tunnel excavator having an agitator is provided to improve the topdressing efficiency of a tunnel excavator by installing an agitator, to heighten work efficiency on excavation to the maximum and to extend the life of equipment by discharging soil and broken rock by a sludge pipe and a sludge valve smoothly, and to cut down the construction cost by shortening a period of construction. CONSTITUTION: The cutter-linked tunnel excavator(100) having an agitator comprises: a body(1) formed in the cylindrical shape to house a sludge pipe(VP), a sludge valve(V) and many motors(M); an internal crusher(2) whose one side is fastened to one side of the body(1), the other side is fixed with many pinion gears(PG) interlocked with the motor(M) and the center is provided with a chamber(3) for collecting the crushed soils, wherein the chamber(3) is fastened with the sludge pipe(VP) and provided with an outlet(4) to discharge the soils; an external crusher(5) fastened with the internal crusher(2) by a main bearing(B) and provided with an internal gear(G) to be engaged with many pinion gears(PG) fixed to the internal crusher(2), a main bearing(B) located between the internal and external crushers(2,5) to make the rotation of the external crusher(5) simply; a cutter face plate(6) whose one side is fixed to the external crusher(5) to form a space with the internal crusher(2) to make the crushed soils flow in and other side is provided with many bits(7) to crush the ground and the bedrock.
