Mounting base, radial interval is uniformly equipped at least two support arms, the bottom edge of support arm on the outside of mounting base
Length direction is evenly spaced to be equipped with multiple cutterheads connected respectively by driving mechanism, driving mechanism include outer case, with
And the driving motor and gear-box of installation in the outer case, the output shaft of driving motor and the driving gear of gear-box connect, tooth
Roller box driven gear lower part is stretched out outside outer case, and the extension stretched out outside outer case is connect with cutterhead, cutterhead include connection ring with
The upper end of three spoke support arms, connection ring is fixedly connected with the extension of gear-box driven gear, on the periphery of connection ring
Spoke support arm there are three radially distributed, each spoke support arm bottom surface outer edge are equipped with a cutter；Or along spoke branch
Arm lengths direction is equipped with two or more cutter, and one of cutter is located at spoke support arm bottom surface outer edge.
The multi-cutter-disk envelope shapes tunneling boring drilling tool, and the sum of diameter of multiple cutterheads is greater than or equal to cutting section
Diameter.
The multi-cutter-disk envelope shapes tunneling boring drilling tool, and the positions and dimensions of multiple cutterheads meet vertical shaft cutting section
All standing driving.
The multi-cutter-disk envelope shapes tunneling boring drilling tool, is equipped with the drive for driving drill boom rotary motion in the cavity of mounting base
Dynamic device.
By adopting the above-described technical solution, the invention has the following beneficial effects:
Multi-cutter-disk envelope of the present invention shapes tunneling boring drilling tool, and cutterhead is set as multiple, and the sum of the diameter of multiple cutterheads
More than or equal to the diameter of cutting section, structure is simple, convenient transportation, and occupied ground area is small, does not need big lifting appliance,
Be conducive to the construction of city narrow space；
Multi-cutter-disk envelope of the present invention shapes tunneling boring drilling tool, and cut direction can be adjusted by driving mechanism, between the knife of track
Away from be no longer it is fixed, big broken net can be formed with a small amount of cutter, and be not likely to produce mud drum hobboing cutter, in tool motion mistake
Cheng Zhongke constantly changes the direction of motion, without certain cutting blade, therefore is not easy to adhere to adhesive, is attached to also can constantly scrape in time
It falls；Cutter running track does not coincide, and repetition percentage of damage is low, is not likely to produce powdery rock slag, causes high viscosity mud, revolve simultaneously
Change with from rotating ratio is adjustable, is more suitable for different geological conditions.
