[0005]

[Operation] The apparatus for compressing crushed pieces and other small pieces of the present invention is designed to introduce the crushed pieces and other pieces generated by the crushing apparatus, contract them by continuously applying pressure, and discharge them. The strips that enter the casing from the strip introduction port above the casing are conveyed downward by a spiral plate that rotates together with the rotating shaft. Since the pitch of the spiral plate gradually decreases downward, the strip is pressurized downward while being conveyed, and its apparent volume shrinks.

[0006] Since there is a spring-loaded door at the discharge port at the lower end of the casing, the pieces transported to the discharge port temporarily remain there. As the strip is further conveyed, the downward pressure applied to the strip by the spiral plate is
When the force exceeds the spring force of the door, the door opens and the debris is ejected out of the casing. Pressure is applied to the discharged pieces so that their apparent volume is contracted, and after this, the pieces, which have been compressed to some extent, enter the recovery container and are compressed to a certain degree by a spiral plate. The door does not open when the downward pressure applied to the strips is small, and only opens when the pressure exceeds a predetermined pressure, so the apparent volume of the discharged strips decreases due to the predetermined pressure being applied. This is a significant decrease.

[0007] Some of the devices for compressing small pieces such as crushed pieces of the present invention are provided with a collection container pressing device that presses the collection container against the periphery of the discharge port in an airtight manner. By pressing the collection container against the periphery of the discharge port in an airtight manner, all the pieces discharged from the discharge port can be collected without exception. Further, since the collection container is pressed in an airtight manner, air will not blow out from the gap when air pressure is generated within the casing.

[0008] In the apparatus for compressing small pieces such as crushed pieces according to the present invention, there is also an apparatus in which the collection container pressing apparatus is provided with a movable carriage part. Since the recovery container pressing device can be easily moved by the trolley portion, it is also convenient when transporting the recovery container after collecting the pieces.

[0009] In the apparatus for compressing small pieces such as crushed pieces according to the present invention, there is also one in which a pedestal that can be raised and lowered is provided on the truck. By loading the collection container on the pedestal and moving the pedestal up and down, the collection container can be easily attached to and removed from the outlet, improving work efficiency.

[0010] Furthermore, the collection container is bottomless, and the bottom plate serving as the bottom of the collection container is provided so as to be movable up and down with respect to the mounting surface of the collection container, so that the collection container can be lowered by the collection container pressing device, and the discharge port door can be lowered. When separating it from the periphery, the bottom plate can also be lowered at the same time. This increases the storage volume in the collection container and prevents the compressed pieces in the collection container from overflowing from above due to expansion due to springback when released.

[0011] Furthermore, if an appropriate amount of water is sprayed or sprayed from a nozzle toward the pieces falling from the discharge port, the pieces will be easily compressed. Also, the pieces can be solidified by spraying adhesive from a nozzle. Also, spraying disinfectant from a nozzle will make it more hygienic. Also, by injecting oil or fuel, the pieces can be used as solid fuel.

The crushed pieces 5 that have entered the casing 3 from the upper crushed piece introduction port 7 are conveyed downward by the spiral plate 6 that rotates together with the rotating shaft 4. Since the pitch of the spiral plate 6 gradually decreases downward, the crushed pieces 5 are pressurized downward while being conveyed, and their apparent volume shrinks.

Since the discharge port 8 at the lower end of the casing 3 has a door 9 which is biased by a spring 10, the crushed pieces 5 that have been conveyed to the discharge port 8 are temporarily retained there. When the crushed pieces 5 are further conveyed and the downward pressure applied to the crushed pieces 5 by the spiral plate 6 becomes greater than the force of the spring 10 of the door 9, the door 9 opens and the crushed pieces 5 are discharged out of the casing 3. Ru. At this time, water is sprayed from the nozzle 14 to reduce springback and facilitate compression. The door 9 does not open when the downward pressure applied to the crushed pieces 5 is small;
