を介して吸水源（図示せず）に連通せしめる。 In the figure, 1 is a dredger, 2 is a spud that fixes this dredger 1, 3 is a main ladder, and 4 is this ladder 3.
5 is a face cutter that is rotatably supported by the sub-ladder 4 and rotates around a vertical axis; 6 is a drive motor for this cutter; 7 is the mud excavated by the face cutter; In the present invention, a cover 8 and a semi-circular rotating hood 9 are arranged on the upper part of the face cutter 5 and on the side surface in the opposite swing direction, and this rotating hood 9 The cover 8 is provided with a mud suction port 10 communicating with the mud suction pipe 7 and a water suction port 11 at a different position. A water intake control valve 12 that opens only when the water pressure at the water intake port 11 drops.
It communicates with a water absorption source (not shown) through.

刃１７を形成せしめる。 Furthermore, as shown in FIGS. 3a and 3b, the face cutter 5 is provided with an annular upper plane blade 14 and a lower plane blade 15 above and below the side excavation blade 13, respectively, so that a gap between the side excavation blade 13 and its rotation axis is provided. A lower excavation blade 17 is formed on the lower surface of the guide blade 16 of the face cutter 5 that connects the face cutter 5.

ター５内に水が取り込まれるようになる。 FIG. 4 shows details of an embodiment of the water intake control valve 12, in which 18 is the water intake control valve, 19 is its suppression spring, 20 is a spring retainer, 21 is a valve case, and 22 is a water intake port provided in this valve case 21. When the pressure inside the face cutter 5 decreases due to the suction effect, the water suction control valve 18, which had been closed by the spring 19, moves downward due to the imbalance of pressure above and below the valve, that is, the water pressure of the water suction source overcomes it. As a result, water is drawn into the face cutter 5 from the outside.
本発明装置によれば下記のような利点がある。 The device of the present invention has the following advantages.
(1) カツター上部及び反スイング方向側面が、カ
バー及びフードで囲われており、不必要な水は
吸引せず効率的な吸泥が可能で、かつ濁りも拡
散しない。(1) The upper part of the cutter and the side in the opposite swing direction are surrounded by a cover and a hood, which allows efficient mud absorption without sucking in unnecessary water, and also prevents turbidity from spreading.
(2) 吸水制御バルブを介し最適必要量の水を送り
込むことにより、効果的な吸泥が可能である。(2) Effective mud absorption is possible by feeding the optimal amount of water through the water absorption control valve.
(3) フードの位置が可変であるから左右両方向に
スイングせしめることができる。(3) Since the position of the hood is variable, it can be swung in both left and right directions.
(4) 下面掘削刃を設けたので下方掘削も可能であ
り、容易にカツターを土中に下ろすことができ
る。(4) Since a lower digging blade is provided, downward digging is also possible, and the cutter can be easily lowered into the soil.
