ものである。Structure of the Invention In order to achieve the above object, the Katsutavi of the present invention includes a cylindrical mounting seat, and two parts fixed on the cylindrical mounting seat in a Y-shape in a plane orthogonal to the axis of the cylindrical mounting seat. It has a book bit part and a support surface that rotatably supports the mounting cylindrical seat around its axis,
and a mounting seat main body provided on the support surface, with a slit of a predetermined length into which a rotation stop protrusion protruding from the lower surface of the mounting cylindrical seat enters to restrict the rotation range of the mounting cylindrical seat to a predetermined range. This allows excavation to be performed even if the cutter head rotates in either the forward or reverse direction.

る。 3 to 5 show the entire Katsutabito according to the present invention. In the figure, 4 is a mounting cylindrical seat, 5,
Reference numeral 6 denotes two bits fixed on the mounting cylindrical seat 4 in a Y-shape in a plane orthogonal to the axis of the mounting cylindrical seat 4, and 7 indicates the mounting cylindrical seat 4 around its axis. The mounting base body supports rotation freely within a specified range.
A slit 9 of a predetermined length into which a rotation stopper protrusion 8 protruding from the lower surface of the mounting cylindrical seat 4 is inserted into the support surface.
is formed, and a bush 10 is interposed between the bearing surface excluding the slit 9 and the mounting cylindrical seat 4. Reference numeral 11 denotes a seal plate attached to the upper surface of the mounting seat main body 7, which functions to prevent dirt and the like from getting caught between the mounting cylindrical seat 4 and the bush 10. Reference numeral 12 denotes a cover on the side surface of the mounting seat main body 7, which is bolted to the mounting seat main body 7 so as to cover the side surface of the mounting cylindrical seat 4 supported by the mounting seat main body 7. A large number of these cutter bits are attached to the outer peripheral surface of the cutter head in a spiral manner, with the axis of the mounting cylindrical seat 4 perpendicular to the spiral.
このような構成で、第６図に示すように、カツ
タヘツド２が右方向に回転すると、一方のビツト

カツタヘツド２が正逆何れの方向に回転したとし
ても、これに連れて両ビツト部５，６が自動回転
し、何れの方向の回転でも掘削が行われる。 With this configuration, as shown in FIG. 6, when the cutter head 2 rotates to the right, one of the bit parts 5 performs digging work, and as shown in FIG. 7, when the cutter head 2 rotates to the left, , the other bit section 6 will perform the excavation work. That is,
Even if the cutter head 2 rotates in either the forward or reverse direction, both bit parts 5 and 6 automatically rotate accordingly, and excavation is performed in either direction.
