The mud collecting device 15 thus formed is attached to the tip of the working arm 10 via the supporting member 41.
In order to dredge the mud D accumulated on the seabed S by the mud collector 15, first, the lid 31, depending on the traveling direction of the hull,
32 apertures are selected. That is, as shown in FIG. 5, when advancing to the left arrow in the drawing, the left valve body 32 is shortened by the actuation cylinder 39 of the opening / closing device 35, so that the left half of the opening 30 of the exterior wall plate 17 is moved. Is opened. In this state, the crane 8 is operated to set the work arm 10 on the seabed S centering on the hinge 11. When the hydraulic motor 26 of the rotary vane portion 16 is operated in this state, the rotary vane 23 is rotated counterclockwise through the rotary plate 22.
This rotation is rotated at the same peripheral speed as the dredging speed, and by this rotation, the soft mud D is sequentially cut off by the rotary blades 23. The cut mud D is accommodated in the compartment 16a between the rotary blades 23 and drawn into the rotary chamber 19 to rotate. The cutting by the rotary blades 23 is made by inserting the accumulated soft mud D from the cutting edge side so as to cut it and cutting it into the partition chamber 16a in a manner that it is stored in the partition chamber 16a. Since the mud D is reduced, the mud D is dredging in a substantially deposited state, so that the mud D having a low water content and a high mud content can be dredged, and the occurrence of pollution can be significantly reduced.

When the compartment 16a accommodating the mud D reaches the outlet 28 opened in the interior wall plate 18, the outlet 2 is also removed.
It is thrown into the scraping conveyor 46 side below 8. The mud D introduced into the scraping conveyor 46 side is vibrated by the sludge member 50 disposed on the carrier side, whereby the mud D is dropped to the lower shooter 53 side and mixed into the mud D. The garbage is separated on the drainboard member 50, and the garbage is collected by the scraping conveyor 46.
It is discharged to the 4 side.

Further, only the mud D is dropped to the shooter 53 side, the mud D is accumulated in the accumulating portion 56 of the mud discharge chamber 55, and the mud D is discharged by the cylinder device 60 to the discharge pipe 73.
It is sent out to the hull 2 side through the above, and is further transferred to the land side by the discharge pipe 4 arranged on the sea surface W.

As described above, according to the mud collecting device 15 of the present embodiment, the cutting by the rotary blades 23 is inserted into the accumulated soft mud D from the cutting edge side so that the soft mud D is cut into almost the entire compartment 16a. Since it is cut out, the suction of excess water is drastically reduced, and the mud D is dredging in almost the accumulated state, so it is possible to dredge the mud D with a low water content and a high mud content, and to generate pollution. Can be significantly reduced. Further, when the compartment 16a containing the mud D reaches the outlet 28 opened in the interior wall plate 18, it is thrown into the scraping conveyor 46 side below the outlet 28. The mud D introduced into the scraping conveyor 46 side is vibrated by the sludge member 50 disposed on the carrier side, whereby the mud D is dropped to the lower shooter 53 side and mixed into the mud D. The wastes are separated on the drainboard member 50, and the wastes are discharged by the scraping conveyor 46 to the waste collection chamber 54 side. Therefore, only the mud D is dropped to the shooter 53 side, the mud D is accumulated in the accumulating portion 56 of the mud discharge chamber 55, and the cylinder device 60 can easily suck and pump. Further, since the water content is small, there is no need for a large-scale precipitation treatment device as in the conventional case, and the treatment becomes easy.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the cutting by the rotary blade is inserted into the accumulated soft mud from the blade edge side to make a cut, and the cut is made almost in the entire compartment. Since it is cut into pieces, the suction of excess water is drastically reduced, and the mud is dredged in almost the accumulated state, so it is possible to dredge mud with low water content and high mud content, and also significantly reduce the occurrence of pollution. be able to. Further, when the compartment containing the mud reaches the outlet opening on the interior wall plate, it is thrown into the scraping conveyor side below the outlet. The mud thrown into the scraping conveyor side is vibrated by the sludge member disposed on the carrier side, so that the mud drops to the lower shooter side, and the dust and dirt mixed in the mud sludge member on the sludge member. The waste is separated by the scraping conveyor and discharged to the waste collection chamber side. Therefore, only the mud is dropped to the shooter side, the mud is accumulated in the accumulating portion of the mud discharge chamber, and the cylinder device can easily suck and pump. In addition, since there is little water, there is no need for a large-scale precipitation treatment device as in the past,
Processing becomes easy.
