A Conveyor-Type Fold A Skirt Apparatus}

The present invention relates to a conveyor type pleated skirt device for the fall prevention of the lower part of the unloading machine shuttle, more specifically, a variety of raw materials, such as ore and coal transported through the ship generated in the process of dropping from the mobile shuttle belt conveyor to the designated loading line The present invention relates to a device for preventing falls and dust.

In general, the unloading work of various raw materials is carried out according to the type, loading yard, loading line conditions, etc. of various raw materials carried through the vessel according to the loading operation plan, and a plurality of unloading machines are selected by line to transfer the raw materials to the loading line. At this time, dust and falls are generated on both sides of the shuttle lower skirt separated from each other by the drop impact of the raw material and the space of the loading line, which causes environmental pollution of the pier.

In particular, since the unloading line and the chute skirt on the loading line are separated and the unloading lines are working simultaneously for each line, the louver skirt is closely attached to the bottom and adjusted to bring 4 pieces from the unloading machines at the front. The raw material transported to the line is in contact with the skirt portion in close contact and serves to help generate the fall of the lower part of the pier. Therefore, in order to prevent this problem, unloading work is performed leaving the lower space of the skirt. However, there is still a problem that fall and dust continue to occur due to the space.

2, the raw material 6 is discharged from the hopper 2 on which the raw material is loaded and transported through the belt conveyor 3, and then the shuttle chute of the shuttle belt conveyor 4. Through (7) the raw material falls to the loading line (5). In this process, the raw material fallout 13 due to the impact drop of the raw material is generated through both space portions between the chute skirt louver 11 and the lower loading line 5.

Since the conventional chute skirt louver 11 is fixed to a skirt support plate (not shown) by the skirt holder 12, it is suitable for a belt conveyor chute, but the chute facility that is moved due to the characteristics of the facility and the job is frequently adjusted according to the conditions of the job. shall. However, since such adjustment is practically impossible, a large amount of dust and falling light are generated during unloading of raw materials, which is a major cause of environmental pollution of the docks.

The object of the present invention was devised to solve the above problems, and prevents falling and dust generated in the skirt during transport of the raw materials from the skirt through the shuttle belt conveyor chute to unload the raw materials to the dock. It is to provide a device that can maintain a comfortable environment.
