摘要： PROBLEM TO BE SOLVED: To sharply suppress the occurrence of rolling and pitching on an excavator by installing multiple split small cutter heads in the plane facing a working face, connecting each small cutter head to an independent cutter drive section respectively, and independently applying a parallel link motion to each small cutter head. SOLUTION: A cutter head 6 is divided into four small cutter heads 6a-6d, four small cutter heads 6a-6d are arranged at the upper, lower, right and left positions, parallel link motions in the opposite directions having the revolving speed suitable for the soil quality of the natural ground G to be excavated are applied to the small cutter heads 6a-6d adjoining vertically and laterally to excavate the natural ground G. The torque reaction of the whole cutter head caused by the excavation of the natural ground G when the parallel link motion is applied to the single cutter head with a large cross sectional area can be reduced, thereby the occurrence of rolling and pitching of a shield machine can be sharply suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a new eccentric multi-axis excavator that can effectively permit the displacement of a cutter frame while facilitating distribution of a control line. SOLUTION: A guide pipe 20 inserting a control line L through to guide it is laid between a cutter frame 2 and a bulkhead 7. One end of the guide pipe 20 is rotatably journalled to the bulkhead 7 side, and the guide pipe 20 is bent to decenter the other end by the distance R of the rotating radius of the cutter frame 2 and to journal the other end to the cutter frame 2 side. The control line L is therefore distributed easily, and the axial and diametrical displacement of the cutter frame 2 is effectively permitted.

摘要： PROBLEM TO BE SOLVED: To provide a new eccentric multi-axis excavator that can effectively permit axial and diametrical displacement generated to a cutter frame. SOLUTION: A rotating cylinder 22 of a bulkhead 7 is provided with an eccentric pipe 26 for making a control line L pass through to the cutter frame 2 side, and the cutter frame 2 is provided with a guide pipe 30 for guiding the control line L extended from the eccentric pipe 26. A clearance permitting the displacement of the guide pipe 30 is formed at a fitting part R between the end of the guide pipe 30 and the end of the eccentric pipe 26. The axial and diametrical displacement of the cutter frame 2 is therefore permitted effectively so as to avoid adverse effect on the rotating cylinder 22 and the bulkhead 7.

摘要： PROBLEM TO BE SOLVED: To provide a position participating in excavation and an unparticipating position, and reduce the excavating torque and the pressing force by half by forming a freely rotatable cutter frame in an umbrella-shaped projection forwarded to the center, and arranging plural cutter bits. SOLUTION: An excavating part 24 of an excavator 21 supports a cutter frame 28 by a partition wall part 23 through a parallel crank mechanism 30 so as to be movable in parallel. A large number of cutter bits 29 are arranged on a front face of the cutter frame 28, and bedrock G is excavated. Since the cutter frame 28 is formed in an almost conical umbrella shape whose central part projects forward, a cutter bit 29 participating in excavation of the bedrock G and an unparticipating cutter bit 29 alternately appear by a rotational position of the cutter frame 28. Excavating torque and pressing force are not necessary for the cutter bit 29 unparticipating in excavation, and a motive power source can be miniaturized. A work space in the excavator also becomes wide, and a work environment is improved, and when an excavating distance is shortened, an abrasion loss is also reduced.
