The above-mentioned conventional refuse collection container is merely a container for collecting refuse, but rather has the following problems. (1) The installation space for trash collection containers is quite large,
It is difficult to obtain the location of the waste collection container. (2) Since the capacity of storing garbage is small, the number of garbage collection vehicles increases and the cost increases. Since the capacity of the garbage collection container to store garbage is small, a large number of garbage collection containers are required for garbage collection. Particularly in cities, it is difficult to obtain the location of the garbage collection, which is a major social problem. It is considered that many of the causes for reducing the garbage storage capacity of the garbage collection container are in the form of garbage. In other words, most of the garbage is stored in a bag made of vinyl or the like and the mouth is closed and discarded. Has an apparent volume much greater than the volume of the garbage entity, which reduces the garbage capacity of the container. Moreover, the garbage bag containing such air is made into an elastic body, and even if it is compressed by a compression device, it is only deformed. When the compression is released, the volume returns to the original volume, and it is difficult to reduce the volume of the plastic bag.

The present invention has been made to solve the above-mentioned problems of the conventional dust compressing apparatus, and an object thereof is to provide a dust compressing apparatus effective for reducing the amount of dust.

[0005]

In order to achieve the above object, a dust compression device according to the present invention includes a bracket mounted on one end and rotatable about a rotating shaft, and a spring connected to the bracket. Two compression plates comprising an engaged push plate and a projection mounted on a bracket such that the tip of the projection protrudes from the surface of the push plate by pressing the push plate,
A drive device for rotating the two compression plates via the rotation shaft is provided so that the surfaces of the respective pressing plates are in contact with each other when the rotation plates are rotated in opposite directions about the rotation shaft. It is provided with.

[0006]

The plastic bag for storing the garbage put in the garbage collection container is compressed between the pair of compression plates provided with the protrusions of the garbage compression device. Because the air is released, the plastic bag is compressed and the volume decreases with the dust inside. Therefore, the capacity of the garbage collection container increases.
