ECCENTRIC MULTI-AXIS EXCAVATOR

摘要

PROBLEM TO BE SOLVED: To provide a new eccentric multi-axis excavator allowing a cutter frame to be attached easily and securely. SOLUTION: One end 3a of a support beam 3 of this eccentric multi-axis excavator is oscillatingly connected to the cutter frame 2 side through oscillating mechanism 11, and the inner diameter of a fit-in hole 4a of a rotor 4 to which the other end 3b of the support beam 3 is fit-in connected is made larger than the outer diameter of the support beam 3. The support beam 3 is therefore oscillated optionally in vertical and lateral directions with the cutter frame 2 side as an axis, and a suitable clearance is formed around the other end 3b of the support beam 3, so that the cutter frame 2 can be attached easily and positively even with slight dislocation between the support beam 3 and the fit-in hole 4a of the rotor 4.
