Abstract

PURPOSE:To efficiently and easily unload soil loaded on a deck of a soil carrier by providing a guide hopper for flowing down soil and sand discharged from the broadsides of said ship on both broadsides of said ship and providing a conveyer for transferring said soil and sand outboard. CONSTITUTION:A carrier B having soil loaded on the deck is advanced and moored in a cut-out portion 2 of a soil unloding ship 1. Under such a condition soil and sand discharged from both braodsides of said carrier B are delivered through hoppers 3 provided on both broad sides of said ship 1 and continuously efficiently transferred to said soil unloading ship 1 by delivering conveyers 4, 4'.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an earth-unloading ship for discharging earth and sand carried by earth-carrying ships.

Conventional technology Conventional soil transport vessels are of the bottom-opening type, and the bottom door opens downward during soil removal, so in shallow water, the bottom door does not open sufficiently, which hinders soil removal, and it is difficult to remove soil all at once. Because of this, it is not possible to remove and spread the earth and sand to an even thickness on the seabed surface, so to eliminate these drawbacks, the deck earth transport vessel B with earth side removal type as shown in Figure 4 has come to be used. Ta.

The deck cargo transport vessel (hereinafter referred to simply as the deck cargo transport vessel) B has a scraper S in the center that moves in the gunwale direction using a hydraulic system, and a dump board that is tiltably attached to the gunwale end. By lowering the dump truck 41iD and pushing out the scraper S, the top sand M on the deck is released from the side.

However, if the earth and sand on the deck cargo transport vessel B is to be transported to another ship or land without being discharged, it is necessary to use a grab bucket, bucket wheel, or gantry crane installed on the ship or land. Unloading equipment must be used, and these unloading equipment are large and heavy, not only severely restricting installation conditions, but also requiring intermittent unloading operations, lacking continuity, and When an earth-lifting vessel equipped with these equipment is placed alongside a deck-loading vessel for transport, the earth-carrying vessel must be moved as the earth and sand is being removed, making mooring operations complicated. This has the disadvantage of making removal work extremely difficult during stormy weather.

Problems to be Solved by the Invention Therefore, the present invention is to continuously carry out the work of lifting and carrying out soil from a deck cargo transport vessel using simple equipment and to eliminate the need for mooring operations.

Means for Solving the Problems The present invention provides a notch in the center of the stern of the earth-lifting ship for pulling in and mooring the deck-loading ship, and on both sides of the ship, the earth and sand discharged from the side of the deck-loading ship are removed. A hopper is provided to guide the sediment downward, and a conveyor is provided to carry the sediment from the hopper out of the ship.

Function: Therefore, the earth and sand pushed out from both sides of a deck earth carrier is continuously carried out overboard via a hopper and a conveyor.

Embodiment An embodiment of the present invention will be explained with reference to FIGS. 1 to 3. FIG. 1 is a side view of the earth-lifting vessel of the present invention, FIG. 2 is a plan view of FIG. 1, and FIG. 2 is a schematic front cross-sectional view illustrating a state in which earth and sand pushed out from both sides of the ship are released onto the conveyor of the earth-lifting ship. As shown in FIG. 2, the earth-lifting ship 1 of the present invention Forming a notch 2 in the center for pulling in and mooring the deck cargo transport vessel B,
Hoppers 3.3' are provided on both sides to guide and flow down the earth and sand M released from the deck cargo transport vessel B, and below the hoppers 3.3' there are hoppers 3.3' with upward slopes along the notches 2, respectively. 1 conveyors 4 and 4' are provided, making it possible to extrude and release earth and sand from both sides over the entire length of the earth transport vessel B.

The earth and sand conveyed by the first conveyors 4, 4' are conveyed to the merging hopper 7 via relay conveyors 5, 5' and 6, 6', flow down from the hopper 7, are discharged by the merging conveyor 8, and are transferred to the outside of the ship via the conveyor 9. will be paid out to.

In addition, the first conveyor 4.4', the relay conveyor 5.5',
6.6', a merging conveyor 8 and a discharging conveyor 9 (the discharging conveyor is not fixed to the above embodiment, but is directly connected to the discharging conveyor by a bucket elevator from the first conveyor 4.4', and the number of conveyors is There is no harm in reducing it.

Effects of the Invention Since the present invention has the above-described configuration, the deck cargo transport vessel enters the notch of the earth lifting vessel and is moored, thereby eliminating the need for ship maneuvering even in stormy weather and improving the stability of the earth lifting work. By increasing the capacity of the earth-lifting vessel and pushing out the earth and sand from the earth-carrying vessel to the earth-lifting vessel, the bucket boiler, which was necessary for the conventional earth-lifting vessel,
Large equipment such as grab buckets is not required, and since the earth and sand are transported by a series of conveyors, the removal work is carried out continuously and the work efficiency is significantly improved. When combined with a cargo transport vessel, the above-mentioned excellent effects can be obtained.
