Abstract

PURPOSE:To prevent a bridge phenomenon at a gate part in time of delivery of powdery granules from occurring as well as to perform delivery operations so efficiently, by installing each air jetting part both upper and lower parts of the gate part on a delivery conveyor of a powdery granule housing hatch. CONSTITUTION:A delivery conveyor 2 is set up in a lower part of a powdery ganule housing hatch 1 via a gate 4. A screw conveyor 5 for raking up granules toward each gate is installed on the gate 4. Each air jetting part 3 is installed at both sides of a hatch lower part at the upper part of the gate 4 and both sides of the delivery conveyor 2 at the lower part of the gate 4. When a bridge phenomenon occurs due to an anele of repose of powdery granules occurs, air is jetted toward the lower part of these powdery granules whereby the bridge is destroyable, thus delivery operations are performable in an efficient manner.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container ship having a traversable screw conveyor at the bottom of the hold.

The dead φ space provided on the belt conveyor has traditionally been necessary for the belt conveyor to discharge the transported items overboard, but since this angle of repose differs depending on the transported item, depending on the specific transported item, This dead space can cause unnecessary spatial waste.

Of course, a container ship that does not carry this belt conveyor requires equipment provided at the container ship/pier (for example, a self-propelled or externally-propelled packet elevator that can be raised and lowered).

However, in the discharge work of this type of container ship, the size of the ship's hatch poses a serious hindrance to the discharge work. ! trL has been developed.

Except for the dead space provided on the conveyor z, an injection nozzle 3 is provided between the bottom of the cabin and the belt conveyor 2 as a function of the angle of repose, and a jet nozzle 3 is provided between the bottom of the cabin and the belt conveyor 2. When the gate 4 of the section is opened, the conveyed items on the gate 4 will collapse. At that time, the injection nozzle 3 injects strong air to the collapsed part of the load to enlarge the collapsed part of the load, thereby causing the stuff to fall onto the belt conveyor 2. At the same time, a rotatable injection nozzle 3 covered with a rubber cover 6 is provided on the ship's wall and the ceiling of the ship, excluding the hatch, to cause the cargo to collapse, and to transfer the transported material to the belt conveyor 2. It is also possible to move it.

In the present invention, the screw conveyor 2 installed at the inner bottom of the hold 1 is installed when the conveyance work is slightly completed in the case of a conveyed object with a heavy specific gravity, or at the same time as the conveyance work is started in the case of a conveyed object with a light specific gravity. By rotating and traveling, the cargo can be transported to the center of the hold 1.

In a container ship carrying several belt conveyors 2, especially when transporting items with heavy specific gravity, the gates 4 of the other 2 belt conveyors are closed except for the 2 central belt conveyors, and these belt conveyors are closed. It is also possible to stop the operation of the belt conveyor 2.

In order to avoid conveyed goods from getting caught between the hold bottom plate and the screw conveyor 5, when the screw conveyor 5 is run from the front to the stern by the drive device 7, the screw conveyor 5 is rotated counterclockwise. let

By the way, this screw conveyor 2 is driven and rotated by a drive device 7 disposed on the port and starboard sides of the inner bottom of the hold 1, and the screws are arranged opposite to each other.

According to the present invention, by rotating the screw conveyor 2 at the same time as the start of the conveyance work or immediately before the end of the conveyance work, there is an effect of shortening the appropriate time.
