To explain this, Fig. 3 is a side view thereof, Fig. 4 is a plan view thereof, 1, St! l is its front view, and the hull 1
A suction ladder 3 is pivotally attached to the end of the suction ladder 3 so as to be able to rise and fall, and a suction mouth 5 is attached to the tip of the suction ladder 3.
そして、サクシタンラダー３を船体１０とともに旋回さ
せるべく、円筒体として形成された旋回筒１１が、船体
１０において鉛直軸線のまわりに回動可能に装着される
とともに、旋回筒１１と船体１０との相対的回動を行な
わせるための駆動機構が設けられている。In order to rotate the succinct rudder 3 together with the hull 10, a swivel cylinder 11 formed as a cylinder is attached to the hull 10 so as to be rotatable around a vertical axis, and the swivel cylinder 11 and the hull 10 are connected together. A drive mechanism is provided for relative rotation.
この駆動機構は、種々の形式が考えられるが、本実施例

外周に形成され歯車１２に係合する歯車部と、歯車１２
を駆動する図示しないモータとから構成されている。Various types of this drive mechanism can be considered, but in this embodiment, a gear 12 mounted on the hull 10, a gear part formed on the outer periphery of the rotating cylinder 11 and engaged with the gear 12, and a gear 12
It consists of a motor (not shown) that drives the.

うになっている。Furthermore, in this embodiment, a pair of thrust generators 14.
14 are arranged. This person's last generator 14.1
4 is configured to be rotatable around a vertical axis, so that the direction of thrust applied to the hull 10 can be changed.

底面４に対して固定されるようになる。- With the above-mentioned configuration, in order to excavate seabed soil by rotating the sacsigin rudder 3 together with the hull 10, first install it in the rotating cylinder 11. 1 Sarasuko Spud + 3.13? , both of them are driven into the seabed surface 4. As a result, the rotating cylinder 11 becomes fixed to the seabed surface 4.
ついで、歯車１２をモータによって駆！ｒ！ＪＪすれば
、旋回筒１１を中心にして船体１０が旋回させられるの
である。Next, gear 12 is driven by the motor! r! JJ causes the hull 10 to turn around the turning cylinder 11.
この時、スラスト発生装置１／１．．１４を駆動して船
体１０の旋回を助８：させるようなスラストを発生させ
ることも可能である。At this time, thrust generator 1/1. ．． It is also possible to generate a thrust that assists the turning of the hull 10 by driving the shaft 14.
１行程分の旋回が完了して、その範囲の掘削が終了した
ならば、船体１０を所要量だけ前進させた後、今までと
反対側に船体１０を旋回させて、次の範囲の掘削を続け
るようにする。Once one stroke of turning has been completed and the excavation of that area has been completed, the hull 10 is moved forward by the required amount, and then the hull 10 is turned to the opposite side to start excavation of the next area. Try to keep going.
この際、船体１０を所要量だけ前進させるには、次のよ
うな種々の手段が用いられる。At this time, the following various means are used to move the hull 10 forward by the required amount.
（１）サクションラダー３を上方へ持ち上げてサクショ

時、旋回筒１１が船体１０に対して相対的ｌこ回動しな
いように、歯車１２を固定しておく。(2) After lifting the suction lug 3 upward and separating the suction mouth 5 from the seabed surface 4, the spant 13 on the opposite side to the direction in which it is to be rotated is pulled out from the seabed surface 4. Next, a thrust is generated by the thrust generator 14.14, and the other one being driven into the seabed surface 4 is
The hull 10 is turned around the book spud 13. At this time, the gear 12 is fixed so that the rotating cylinder 11 does not rotate relative to the hull 10.
このようにして、１行程分だけ船体１０を旋回させれば
、海底面４へ固定されていないスパッド１３も船体１０
とともに旋回するようになり、その位置は前進する。In this way, by turning the hull 10 by one stroke, the spud 13 that is not fixed to the seabed surface 4 can also be rotated by the hull 10.
It will begin to rotate with the robot, and its position will move forward.
その後海底に打ち込むスパッドを交替して、今度は、今
までと逆回りに船体１０を旋回させ、船体１０が１往復
した時点でスパッド４３．１３を両方とも海底に打ち込
む。Thereafter, the spuds to be driven into the seabed are alternated, and this time, the hull 10 is turned in the opposite direction, and when the hull 10 has made one reciprocation, both spuds 43 and 13 are driven into the seabed.
上述の操作の結果スパント１３．１３の打ち込み位置は
、−往復する前の位置より前進しており、これによって
船体１０が前進させられるのである。As a result of the above-mentioned operation, the driving position of the spant 13.13 is further advanced than the position before reciprocating, and the hull 10 is thereby moved forward.
（３）旋回筒１１に装着されたスパッド１３．１３と別

It is also possible to move the hull 10 forward in the same manner as in the previous section (2) by using 3'.
このようにして船体１０を前進させた後、サクションラ

削が続けられるのであ兎。After the hull 10 is moved forward in this manner, the suction ladder 3 is lowered to bring the suction mouth 5 into contact with the seabed surface 4, and the gear 12 is again driven by the motor to rotate the hull 10 around the rotating tube 11. If we let them, the excavation of seabed soil will continue.
このようにして、船体１０から離れた海底面４へ錨を打
ち込むことなしに、船体１０を容易に旋回させ、海底土
の掘削が行なえるようになる効果が得られる。In this way, it is possible to easily turn the hull 10 without driving an anchor into the seabed surface 4 remote from the hull 10, thereby making it possible to excavate seabed soil.

る。As described in detail below, the dredger of the present invention is provided with a dredging rudder pivotally attached to the end of the hull so that it can be raised and lowered, and in order to rotate the dredging rudder together with the hull, the dredging vessel is provided with a A rotatably mounted cylindrical body and a drive mechanism for relative rotation between the cylindrical body and the hull are provided, and a spud for fixing the cylindrical body to the seabed is raised and lowered by the cylindrical body. This extremely simple configuration allows the ship to turn without using an anchor, and it also allows the ship to move forward and continue digging, reducing the time and effort required for dredging work. This has the effect of significantly reducing the amount of water, eliminates the need for an auxiliary curved boat that was previously required, and has the advantage of being able to reliably rotate the hull to perform excavation even in soft seabed ground.
