Description

[Detailed Description of the Invention] This invention relates to a self-unloader ship that is capable of efficiently handling cargo in a ship's hold.

Conventional self-unloading ships have a belt conveyor installed at the bottom of the ship's hold, and the cargo in the hold is lifted by this belt conveyor. There was a problem in that the cargo remained on both sides of the hold, making it impossible to unload cargo in those areas.

This invention solves the above-mentioned problems and provides a self-unloader ship that can efficiently unload cargo without leaving any parts on either side of the hold. a belt conveyor provided in the duct along the duct; and both side edges provided on the upper surface of the duct over its entire length so as to cover the belt conveyor in the duct. a bendable load-receiving belt that engages with stepped portions provided at the upper ends of both side walls of the duct, and a tractor that is movably provided in the hold in the longitudinal direction on both sides of the duct as rails. and a plow plate provided on the tractor and having a width and height substantially the same as the hold, and having a through hole in the center of its lower part for passing the load receiving belt, and tilting upward; a screw conveyor provided in the lower part of the plow plate in its width direction; and a screw conveyor provided near the through hole of the plow plate of the tractor.
The present invention is characterized in that it comprises a load receiving belt lifting roller for sequentially lifting the load receiving belt higher than the screw conveyor and passing it through the through hole as the tractor moves.

Next, one embodiment of this invention will be described based on the drawings.

FIG. 1 is a schematic sectional view showing the main part of this invention, and FIG. 2 is a schematic perspective view with a part of the main part cut away. In the drawing, 1 is the hull, 2 is the hold, 3 is the double bottom,
4 is a duct provided at the center of the double bottom 3 along the longitudinal direction; 5 is a belt conveyor provided within the duct 4; 6 is a hopper for collecting cargo transferred by the belt conveyor 5; 7 is a hopper. 6 is a vertical conveyor installed upright, 8 is a chute provided on the top of the vertical conveyor 7, and 9 is a conveyor for transferring the cargo transferred by the vertical conveyor 7 and discharged from the chute 8 out of the ship.

The above configuration is the same as the conventional device, but in this invention, in order to prevent the load of the cargo in the hold from directly acting on the belt conveyor 5, there is a A load receiving belt 10, a part of which is shown in a plan view in FIG. 3, is provided.

As shown in FIG. 3, the load receiving belt 10 is formed into a bendable band shape by a plurality of links 10a and a plate 10b, and FIG. 4 shows an enlarged cross-sectional view of the load receiving belt supporting portion. As such, both side edges thereof are engaged with step portions 11 provided at the upper ends of both side walls of the duct 4.

Reference numeral 12 denotes a tractor installed inside the boat hold 2 so as to be movable in the longitudinal direction. A plow plate 13 is provided which is inclined towards the ship, and at the bottom of the plow plate 13, a screw conveyor 14 is disposed with its blades facing oppositely to each other for scraping cargo toward the center of the hold 2 in the width direction. There is.

15 is a through hole provided at the center of the lower part of the plow plate of the tractor 12 for passing the load receiving belt 10; 16 and 17 are holes of the tractor 1 in the vicinity of the through hole 15;
2, as the tractor 12 moves, the load receiving belt 10 is sequentially moved to the screw conveyor 1.
This is a roller for lifting the load-receiving belt for lifting it higher than the load receiving belt 4 and passing it through the through hole 15.

The tractor 12 is provided with a drive wheel 12' at its lower part, and the drive wheel 12' allows the stepped portion 11 of the duct 4 to be used as a rail, as shown in the enlarged cross-sectional view of the drive wheel support portion in FIG. It runs with no power source. Also screw conveyor 14
is driven by a power source (not shown) built into the tractor 12.

Since this invention is configured as described above, by running the tractor 12 and driving the screw conveyor 14, the ship's hold 2
The cargo inside can be collected on the belt conveyor 5 in the center of the hold and unloaded efficiently. On this occasion,
The tractor is equipped with an upwardly sloping plow plate that has approximately the same width and height as the ship's hold, so even if the cargo in the hold is, for example, sticky coal, this plow plate will was cut down by
It can be easily loaded.

In addition, a bendable load-bearing belt is provided on the upper surface of the duct to cover the belt conveyor inside the duct, so the load of cargo in the hold does not directly act on the belt conveyor. . Moreover, the part of the load receiving belt that passes through the screw conveyor is automatically moved higher than the screw conveyor as the tractor moves, by a roller for lifting the load receiving belt installed on the tractor near the through hole of the plow plate. Since it is raised high and returned to its original position after the tractor has moved, there is no problem with the movement of the tractor and the screw conveyor, and the belt conveyor can be reliably covered. Furthermore, since the tractor moves as rails on both sides of the duct covered with load receiving belts, cargo does not accumulate on the rails, allowing the tractor to move smoothly.

As mentioned above, this invention brings about many excellent effects.
