TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linked belt conveyor and a method of using the same, and more particularly, to a linked belt conveyor that facilitates and excavates in a narrow tunnel by making the installation cross-sectional area of the continuously connected belt conveyor narrow and uniform. And about its usage.
[0002]
[Prior art]
When a general belt conveyor is connected continuously, when articles are transferred from one belt conveyor to another belt conveyor, the articles are formed due to a depression formed between the two conveyors. In some cases, it is difficult to transfer smoothly.On the other hand, when the belt conveyors are layered on top of each other, since articles are transferred from one belt conveyor to the other belt conveyor in a falling manner, the drop between the two belt conveyors is reduced. It has a great influence on the smooth transfer of goods.
[0003]
In addition, in the case of continuous connection, it has been considered to reduce the diameter of the tail pulley in one belt conveyor and form it as a sword-point while bringing the tail pulley as close as possible to the head pulley in the continuous belt conveyor on the other side. However, simply reducing the diameter of the roller causes the conveyor to bend downward due to the weight of the article, thereby increasing the rotational friction of the head roller.
[0004]
However, in excavation work and the like in narrow tunnels, it is necessary to consider not only the removal of excavated soil but also the movement of workers. It is an important task to arrange them.
[0005]
That is, the belt conveyor needs to have an area for continuous installation as small as possible, and when installed at the same time, smoothness without generating a step on the upper surface of the belt conveyor is required. .
[0006]
However, since there is no conventional belt conveyor suitable for these requirements, it is hoped that a new belt conveyor will be developed to make excavation work in a narrow tunnel easier and more efficient. is the current situation.
