本発明は、自航式サクション浚渫船等に用いられるカッ
タイーｊきドラグヘッド装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drag head device for use in self-propelled suction dredgers and the like.

蓄えるようにしながら浚渫を行なっている。In general, a self-propelled suction dredging port ;) is installed in Ql) by attaching a drag head 3 of 1 = 1 digit to the tip of the drag arm 2 and grounding it on the seabed soil 4, as shown in Figure 1 (schematic diagram). Dredging is carried out while suctioning seabed soil 4 using a dredging pump and storing it in a hopper 1.

リング効果により、海底土を浚渫することがで終る。By the way, as the drag head 3, a California type drag head 5 as shown in the ft52 diagram (side view) has been conventionally used. , the seabed soil is dredged by the scouring effect of excavating and moving the seabed soil by the water flow at the 2' end of the water pipe 6.

いる。In addition, the reference numeral 7 in FIG. 2 indicates a claw, and the reference numeral 8 indicates an inlet member.
しかしながら、このような従来のドラグヘッド装置では
、海底土が硬く締っている場合には、浚渫能力が著しく
低下するという欠点がある。However, such conventional drag head devices have the disadvantage that their dredging ability is significantly reduced when the seabed soil is hard and compact.
そこで、従来、内部に回転式カッタを装備したカンタイ

水深等の変化に対応でとるようになっている。In addition, in the cutter drag hend device shown in FIG. 4, a drag head with a cutter is placed on the posture stabilizing sled 14 to keep the excavation depth 31 constant.
With this drag hand device, the drag hand
A hinge 17 is provided between the hand A and the suction 1'' member 15 to accommodate changes in water depth, etc.
ところで、カンタを駆動する動力が一定の場合、海底土
４が硬質のとぎには掘削深さＬを薄くする必要があり、
逆に海底土４が軟質の場合には、掘削像さｔを厚くして
掘削土量を多くすることができる。By the way, when the power to drive the canter is constant, the excavation depth L needs to be thinner when the seabed soil 4 is hard.
On the other hand, if the seabed soil 4 is soft, the excavated soil volume can be increased by increasing the thickness of the excavated image s.

た、軟質の海底土４を掘削するときの力。However, in the case of a canter drag hend device as shown in Fig. fiS4, the excavation depth L is constant, so it is fixed at a certain depth E. If the cutter is fixed at the excavation depth when excavating hard submarine soil 4,
When excavating soft seabed soil 4, the hydraulic motor 16 has more power than necessary, and the power when excavating soft seabed soil 4 is too large.
