Description of the Related Art Conventionally, a bulk unloading ship self-unloading system in which bulk goods such as coal, limestone, steel stone, and wood chips are directly loaded in a bulk loading state without being packed in a cargo hold provided in a ship's hold. For example, as disclosed in Japanese Utility Model Publication No. 51-11400, an unloading system for unloading bulk material from a cargo hold has been conventionally provided.

へ搬送させる構成である。However, it is difficult to use an automatic unloading system such as that disclosed in the above-mentioned publication, since bulk materials such as wood chips have poor fluidity and may cause packing, as shown in FIG. Such a conventional unloading system is used. This unloading system is equipped with a cargo hold 2 provided on the ship hold 1a.

Further, when the cargo handling work progresses and the amount of the loose pieces in the cargo hold 2a decreases, it becomes difficult to grasp the loose pieces by the bucket 5a, and the machinery such as the backhoe is put in the cargo hold 2a in which dust and the like are suspended, and the discharging work is performed. It is necessary to provide assistance, which reduces the efficiency of cargo handling and imposes a severe working environment on the backhoe operator. Further, this system has a problem in that it is impossible to operate automatically, so that it is difficult to save labor such as requiring a large number of workers.

At the same time, dust generated from loose materials can enter the work site and is extremely bad for hygiene management.

なしに荷揚げすることができる。As described above, according to the present embodiment, it is possible to automatically convey the loose material to the ship without opening the hatch 7 provided on the upper deck 6 and without requiring many workers. Is. In particular, the cargo hold 3 has a hopper shape, and the reclaimer 12 has a horizontally extending cantilevered screw 15 rotatably arranged on a rotation shaft provided inside the bottom wall 9 at the center thereof. Scrape out. Therefore, it is possible to unload a loose material, such as a wood chip, which has a relatively light weight and a large internal friction angle, and therefore has poor fluidity, automatically and efficiently without causing clogging.

に保守などの面で経済的にも有利である。Further, a cantilever type screw 15 extending near the side wall 10 of the cargo hold 3 rotates at the base end located at the center of the bottom wall 9 and moves along almost the entire inner surface of the circular bottom wall 9. Therefore, there is no worry that the scraping will be done surely and completely, and there will be no unpacking. In addition, the screw 15
Can be scraped out over the entire surface of the bottom wall 9 by providing only one cantilever type, which is economically advantageous in terms of production and maintenance.

体とした構成であってもよいことは言うまでもない。In this embodiment, one screw 15 is arranged, but if necessary, a plurality of screws 1 may be provided.
The scraping efficiency can be improved by arranging 5 radially at appropriate intervals. Further, in this embodiment, since the conveyor 25 has the lateral transfer section 26 extending in the hand direction of the hull and the vertical transfer section 27 extending upward on the ship, they are integrally connected to each other. Although it has an advantage that the bulk material taken out from the container 8 can be quickly transferred to the ship, the lateral transfer unit 27 and the vertical transfer unit 28 may be configured separately. Needless to say.

It removes bulk material from the entire inside of the bottom wall without clogging it, especially with relatively light weight, such as wood chips, which has a large internal friction angle, and therefore can efficiently handle bulk material with poor fluidity. It can be unloaded automatically and without clogging, and dust is blown up to the surroundings because the bulk is discharged from the bottom of the cargo hold without opening the hatch on the upper deck. In addition, there is no need to carry a machine such as a backhoe into the cargo hold where dust is generated, and there is no problem in hygiene management.
