一般的にベルトコンベヤである。That is, the automatic cargo handling equipment comprises first conveyor means extending in the longitudinal direction of the hull along the bottom of the cargo hold, and second conveyor means extending from near the bottom of the ship to above the upper deck.
A third conveyor means extending to a predetermined location on the wharf, and a scraping means for supplying the bulk material of the cargo hold to the first conveyor means, wherein the bulk material loaded in the cargo hold is provided at the bottom portion. From the first conveyor means and landed on the wharf by passing from the first conveyor means to the second and third conveyor means, each conveyor means being typically a belt conveyor.

And a third conveyor means for discharging the bulk material received therefrom to a predetermined location on the wharf, and incorporating the first and second conveyor means in a duct constructed on the hull. A duct carrying a second conveyor means, having a bulk carrier equipped with an automatic cargo handling facility having a configuration in which a third conveyor means is installed on a boom that cantilevered on the upper deck so that it can be raised and lowered. The above-mentioned section in which rainwater and seawater enter and cause flooding of not only the conveyor means but also the hold and the cargo hold because the bulk material is opened at the place where bulk materials are transferred to the third conveyor means. It has been made on the basis of.

1 closed watertight. That is, as shown in FIGS. 2A and 2B, a guide groove 42 which protrudes outward from the peripheral edge in the vicinity of the opening 27 at the lower end of the chute 26 is provided. The opening 27 is opened and closed by being fitted into the guide groove 42 and linearly moved by a motor 43 composed of a fluid pressure cylinder. When the prime mover 43 is not operated, the door 41 is placed in the closed position, and packing (not shown) for closing a gap between the guide groove 42 and the door 41 is provided on one or both of them.

前述の扉体４１と同じである。Next, the present invention is water-tight by the first conveyor means C 1 from the second opening 25 is also the same door body 44 of the chute 24 provided to pass rose was the conveyor means C 2 Was closed. That is, as shown in FIG. 3, a guide groove 45 projecting outward from the periphery near the opening 25 at the lower end of the chute 24 is provided, and the flat door body 44 linearly moved by a motor 46 composed of a fluid pressure cylinder is provided. The peripheral portion is fitted into the guide groove 45 to form the opening 2.
5, the motor 46 puts the door body 44 in the closed position when not operating, the door body 44 opens the opening 25 only at the time of unloading, but is closed otherwise. Enhancing the watertightness by using packing is the same as the door 41 described above.

の各扉体４１，４４と同じである。Further, in the illustrated embodiment, belt conveyors 16 and 17 for transferring bulk materials taken out of two cargo holds 8, 9 and 10, 11 provided in two spaces watertightly shut off from each other by partitions 3, 4, 5 respectively. Duct with built-in
The opening 20 communicating with the opening 9 is also closed in a watertight manner by the same door 47 as described above. That is, as shown in FIG. 4, a guide groove 48 which protrudes outward from the peripheral edge in the vicinity of the opening 20 at the lower end of the chute 19 is provided, and a flat door 47 which is linearly moved by a motor 49 comprising a fluid pressure cylinder is provided. The periphery is fitted into the guide groove 48 to open and close the opening 20. The prime mover 49 places the door 47 in the closed position when not operating, and the door 47 opens the opening 20 only when unloading. At other times, the doors are closed and packing is used to increase water tightness, which is the same as that of the doors 41 and 44 described above.

るものである。As described above, the upper deck of the duct incorporating the conveyor means for transporting the bulk material taken out from the bottom of the cargo hold to the upper deck from near the bottom of the automatic cargo handling equipment for unloading from the upper deck. According to the present invention in which the opening for transferring bulk materials that is open upward is closed in a watertight manner, rainwater or seawater enters the duct from the opening during stormy weather, and seawater flows from the opening through the opening when a rollover accident occurs. It does not flow into the body in large quantities, protects the conveyor means from problems such as rust and electric leakage, protects the hold and cargo hold from flooding, and further reduces the danger of sinking.
