PURPOSE:To land gathered marine resources with high efficiency by its own force by forcing a scraper bucket to reciprocate along an inclined surface from a hull to carry out stored bulk material, and landing the same by a rotary conveyer on the gunwale side, the inclination of which can be freely adjusted. CONSTITUTION:One wall surface 3 extended from a hull 1 to a hold 2 is inclined, and a scraper device 10 for scraping up stored resources in the hull from the inclined surface is provided. The device 10 includes a scraper bucket 11 and a rope device for forcing the bucket to reciprocate, which is provided in the forward and backward direction of the bucket 11. Two, right and left scraper devices of three scraper devices are constructed so that the tail sheave 15 is capable of freely moving in the cross direction. A control device makes three bucket devices reciprocate alternately, and adjusts the lateral direction of the sheave 15 while the remaining status of stored resources by a TV camera to conduct scooping with good efficiency. The scooped marine resources are carried to the gunwale side and landed to a desired device on land by a rotary conveyer 20, the inclination of which can be freely adjusted.
