Field of the Invention The present invention relates to a continuous type of unloading machine, and in particular, it is possible to improve the unloading efficiency through variable control of the cargo capacity in the process of unloading bulk cargo such as coal, grain, cement, .

Generally, the cargo is unloaded to the outside of the ship using a bucket continuously attached to the elevator to unload the bulk cargo loaded on the ship.

Such a bucket elevator type continuous unloading machine generally comprises a bucket elevator having a bucket installed in a bucket chain connected to a sprocket, and a foot portion of the bucket elevator carries the bulk cargo to the uppermost portion of the bucket elevator, As shown, the bulk cargo is unloaded to the dock by transporting it to the dock conveyor through the boom conveyor 600, the central chute 610, the hopper 620, the feeder 630 and the gantry conveyor 640.

However, since the feeder 630 is installed under the hopper 620 of the central chute 610, the continuous loader can stably secure a fixed load through the gantry conveyor 640, And the gantry conveyor 640 are separated from each other, so that it is difficult to secure many vertical spaces.

In addition, such a continuous type unloading machine has a complicated structure, has a high overall height, causes an increase in weight, and has a problem of inefficiency in which only a limited loading capacity can be controlled.

In case of instantaneous overload, the central chute is blocked and the work is stopped and the unloading efficiency is lowered.
