回転式カッタ、３はこの回転式カッタ２の回転軸、４は
この回転軸３を回転駆動する油圧モータ、５は回転軸３
を本体１に対して揺動自在に支持するスイベルジヨイン
ト。In the figure, 1 is the excavator main body, 2 is a rotary cutter provided at the tip of the excavator main body 1, 3 is the rotating shaft of this rotary cutter 2, 4 is a hydraulic motor that rotationally drives this rotating shaft 3, and 5 is a rotating Axis 3
A swivel joint that swingably supports the main body 1.
６はこのスイベルジヨイント４を介して上記回転式カッ
タ２を揺動駆動する揺動ジヤツキである。Reference numeral 6 denotes a swinging jack that swings and drives the rotary cutter 2 via this swivel joint 4.
上記回転式力ツメ２の回転軸３にはシリンダ７が構成し
あって、これに先導プランジャ８が回転式カッタ２の前
方へ突出自在に設けである。A cylinder 7 is formed on the rotating shaft 3 of the rotary force claw 2, and a leading plunger 8 is provided in the cylinder 7 so as to be able to project forward of the rotary cutter 2.
そして上記シリンダ７の前後の室にはスイベルジヨイン
ト４を介して選択的に圧油を供給可能にした油圧配管９
，１０が接続されている。Hydraulic piping 9 is capable of selectively supplying pressure oil to the chambers before and after the cylinder 7 via the swivel joint 4.
, 10 are connected.
上記構成において、通常の掘進時には単にカッタ２を回
転して掘進する。In the above configuration, during normal excavation, the cutter 2 is simply rotated to advance the excavation.
そして第６図Ａに示すように先導部の推進方向がずれた
場合に、これを方向修正するには、まず第６図Ｂに示す
ように、停止状態の回転式カッタ２を揺動ジヤツキ６に
て所定の方向を向くように揺動し、ついで先導プランジ
ャ８を突出動して土中に突入させる。If the direction of propulsion of the leading section deviates as shown in FIG. 6A, in order to correct the direction, first move the stopped rotary cutter 2 to the swinging jack 6 as shown in FIG. 6B. The guide plunger 8 is then swung to face a predetermined direction, and then the leading plunger 8 is moved to project and plunge into the soil.
この状態で第６図Ｃに示すように回転式カッタ２を回転
駆動して掘削することにより修正された方向に掘削され
る。In this state, as shown in FIG. 6C, the rotary cutter 2 is driven to rotate to excavate in the corrected direction.
本考案は以上のようになり、掘進機本体１の先端に、回

方向修正の際に回転式カッタ２を揺動した後、先導プラ
ンジャ８を突出してから回転式カッタ２を回転駆動する
ことにより回転式カッタ２は土中に突入した上記先導プ
ランジャ８に支持される状態となって、この先導プラン
ジャ８を先導にして曲がることなく掘削され、従来に比
べて方向修正能力を大幅に向上させることができる。The present invention is as described above, and in an excavation machine for maintenance work in which a rotary cutter 2 is swingably provided at the tip of the excavation machine body 1, the rotary cutter 2 is attached to the rotary shaft 3 of the rotary cutter 2. Since the leading plunger 8 is provided which can freely protrude from the tip,
After swinging the rotary cutter 2 during direction correction, the leading plunger 8 is projected, and then the rotary cutter 2 is driven to rotate, so that the rotary cutter 2 is supported by the leading plunger 8 that has plunged into the soil. With this leading plunger 8 as a guide, excavation is carried out without bending, and the ability to correct the direction can be greatly improved compared to the conventional method.
