This is a system that guides and intervenes above. In addition, instead of the above-mentioned means,
It is also possible to adjust the angle manually from the work boat using a hydraulic circuit or the like based on the seabed conditions surveyed in advance.

Next, the means for volatilizing the accumulated material will be explained based on the above embodiment. When the ore collector (A) is towed or self-propelled along the seabed by an offshore work boat, the cutting body (0 ) The cutting blade (9) provided at the tip of the
is effectively guided to the accumulation guiding path αe through the flow path Qυ formed on the cutting body (0). On the other hand, the pressurized water pressurized into the duct 04) by the pump a9 is connected to the pressure water supply. The duct (1~ is press-fitted into the cutting body (G),
Furthermore, the pressurized water becomes a seawater jet flow from the hole α mark provided on the guiding slope α2 of the cutting body (0), passes through the ore collecting duct (C17) via the accumulated material guiding path αe, and is transferred to the ore concentrator (B). The water flows into the hoppers (4) and (5).

At this time, the accumulated material Q (1 and mud introduced into the accumulated material guideway side from the flow path Qυ on the cutting body (C) due to the advancement of the ore collecting machine) and the suction action by the seawater jet flow are removed by this seawater jet. It is carried along by the flow through the ore collecting duct αη and into the hoppers (4) and (5).

In the hoppers (4) and (5), the specific gravity /l-
The sludge is discharged to the outside from the sludge outlet (8) at the rear of the hopper by the seawater jet flow, and becomes an accumulation α [
The particles settle in the hoppers (4) and (5), and are transported to the recovery section (
7), and the collected material (b) collection pipeline (3), one end of which communicates with the collecting section (7), allows only the collected material to be collected by the work boat (2).

As described above, according to the present invention, 1. Pressure water is introduced into the hollow part formed in the cutting body, and this pressure water is ejected as a seawater jet stream from the hole provided in the guiding slope formed at the rear of the cutting body, By passing the seawater jet flow through the ore collecting duct that connects the cutting body and the ore concentrator, the accumulated material and mud guided by the cutting body to the tip of the ore collecting duct are conveyed by the water flow, and only the accumulated material is transported in the ore concentrator. This can be separated and collected by an offshore work vessel, and compared to conventional methods of collecting accumulated material using a jet stream using a nozzle, a powerful seawater jet stream can be obtained, and the collected material can be collected more efficiently. It has excellent features such as improved separation efficiency from mud and mud.
