[Problems to be solved by the invention]
In each of the above-mentioned two-layer type compression-type garbage collection vehicles, since each container is provided with a storage box corresponding to a different garbage and each storage box, a loading box and a loading device are provided. It is possible to collect two different types of separated dust at the same time, thereby improving the efficiency of the collection work.
