[0005]

The compaction device for crushed pieces such as crushed pieces of the present invention is designed to introduce crushed pieces such as crushed pieces generated by the crushing apparatus and to continuously apply pressure to shrink the pieces and discharge them. The strip that has entered the casing from the strip introduction port above the casing is conveyed downward by a spiral plate that rotates with the rotating shaft. Since the pitch of the spiral plate is gradually decreased downward, the strip is pressed downward while being conveyed, and the apparent volume is contracted.

Since the discharge port at the lower end of the casing has a spring-biased door, the strip conveyed to the discharge port temporarily stays there. The strip is further transported, and the downward pressure applied to the strip by the spiral plate is
When the force of the spring of the door exceeds the force of the door, the door opens and the strips are discharged to the outside of the casing. The discharged strips are in a state in which the apparent volume is contracted by applying pressure, and thereafter the strips compressed to a certain degree enter the recovery container and are compressed by the spiral plate to a constant shrinkage. The door does not open when the downward pressure applied to the strip is small, but it opens only when the pressure exceeds a predetermined pressure, so the strip that is discharged has a certain apparent volume It will be greatly reduced.

Some of the compression devices for crushed pieces such as crushed pieces of the present invention are provided with a collection container pressing device that presses the collection container around the discharge port in an airtight manner. By pressing the recovery container in an airtight manner on the periphery of the discharge port, it is possible to recover all the fine particles discharged from the discharge port. Further, since the recovery container is pressed in an airtight manner, air is not blown out from the gap when air pressure is generated in the front casing.

In the compression apparatus for crushed pieces such as crushed pieces of the present invention, there is one in which the collection container pressing device is provided with a freely movable carriage portion. The trolley facilitates the movement of the collection container pressing device, which is convenient when transporting the collection container after collecting the debris.

In the compression device for crushed pieces such as crushed pieces according to the present invention, there is also one in which a pedestal capable of moving up and down is provided on the same truck portion. By loading the collection container on the pedestal and moving the pedestal up and down, the collection container can be easily attached to and detached from the discharge port, so that workability is improved.

Further, the recovery container has no bottom, and a bottom plate serving as the bottom of the recovery container is provided so as to be movable up and down with respect to the mounting surface of the recovery container, whereby the recovery container is lowered by the recovery container pressing device, and the discharge port door The bottom plate can be lowered at the same time when it is separated from the peripheral edge. This increases the storage volume in the collection container and prevents the compressed strips in the collection container from overflowing from above the collection container due to bulging due to springback when opened.

Further, if an appropriate amount of water is sprayed and sprayed from the nozzle toward the strips falling from the discharge port, the strips can be easily compressed. If the adhesive is sprayed from the nozzle, the strip can be solidified. Also, spraying the disinfectant from the nozzle makes it sanitary. Also, by injecting oil / fuel, the strip can be used as a solid fuel.
