[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag breaking machine for breaking garbage bags such as plastic bags containing garbage.

[0002]

2. Description of the Related Art Conventionally, a bag breaking machine has been disclosed in Japanese Patent Publication No. 2-320.
As shown in the publication No. 26, a weight having a bag-breaking blade is swingably provided in an annular blade, and a garbage bag such as a plastic bag put in the annular blade is removed from the annular blade. When passing between the blade and the weight, the bag is broken by the bag breaking blade of the weight and the dust in the dust bag is taken out.

[0003]

However, in the above-described conventional apparatus, the size of the garbage bag varies depending on the amount of the garbage stored in the garbage bag. Even if the garbage bag cannot be broken because it cannot pass between the weight and the weight, or if it can pass between the annular blade and the weight, the pressing force on the garbage bag by the annular blade and the weight is strong. To destroy even the garbage in the garbage bag.

[0004]

According to the bag breaking machine of the present invention, a cylindrical storage container for storing garbage bags containing garbage is rotatably supported, and a spiral blade is provided on the inner wall of the storage container. On the other hand, a rotation shaft is rotatably supported substantially coaxially with the rotation center of the storage container, and at least two or more types of linear members having flexibility and different lengths are suitable for the rotation shaft. Several are protruding.

[0005]

[Function] A garbage bag such as a plastic bag put into a storage container is conveyed to the garbage discharge port side by the action of a blade accompanying the rotation of the storage drum, and the garbage bag is removed by rotation of a flexible linear member. Hit to break the bag.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 schematically shows a refuse treatment system provided with a bag breaking machine according to the present invention.

In FIG. 1, reference numeral 1 denotes a bag breaking machine. The crushing machine 1 receives, for example, garbage (contained in a garbage bag such as a plastic bag) discharged from a garbage truck C via a hopper 2. In addition to storing the garbage, the garbage bag containing the garbage is broken and then discharged to the sorting conveyor 3 or the like.

As shown in FIG. 2, the bag breaking machine 1 has a cylindrical storage drum (storage container) 11 supported by rollers 12 so as to be rotatable about a substantially horizontal axis. Trash inlet 13 with the hopper 2 connected to
Are formed, and a dust discharge port 14 is formed at the other end.

A gear 15 is provided on the peripheral surface of the storage drum 11, and a chain 17 driven by a drive motor 16 is wound around the gear 15. The drive motor 16 drives the chain 17 to store the gear. The drum 11 is driven to rotate.

A helical blade 18 is provided on the inner wall of the storage drum 11 along the inner wall, and the garbage bag put into the storage drum 11 by the rotation of the storage drum 11 is fed to the garbage discharge port 14. It is configured to be conveyed toward.

A rotary shaft 20 is rotatably supported substantially coaxially with the center of rotation of the storage drum 11 through a dust inlet 13 through a dust outlet 13.

A sprocket 21 is provided at one end of the rotating shaft 20, and a chain 23 is wound around the sprocket 21 and a sprocket 24 provided on the rotating shaft of a drive motor 22, and the sprocket 24 is driven by the drive motor 22. The rotation shaft 20 is driven to rotate by driving the chain 23 through the shaft.

Further, a plurality of linear members 30 protrude from the rotating shaft 20. The linear members 30 are arranged at predetermined intervals in the axial direction of the rotating shaft 20 and radially in the radial direction.

As the linear member 30, for example, a wire having flexibility is used, and three types having different lengths are used as shown in FIG.

The storage drum 11 and the rotary shaft 20 are rotated in opposite directions.
The rotation speed of the storage drum 11 is set to low speed, and the rotation speed of the rotating shaft 20 is set to high speed. Specifically, for example, the rotation speed of the storage drum 11 is set to 6 rpm, and the rotation speed of the rotating shaft 20 is set to 100 rpm.

By constructing the bag breaking machine 1 in this manner, a garbage bag such as a plastic bag inserted from the garbage collection vehicle C through the garbage inlet 13 is operated by the blade 18 accompanying the rotation of the storage drum 11. , The garbage bags being conveyed by the rotation of the rotary shaft 20 along with the rotation of the rotary shaft 20 continuously hit the garbage bags, thereby breaking the garbage bags and breaking the garbage bags. Take out the trash.

Here, since the linear member 30 is flexible, even in a large garbage bag in which garbage is fully filled, after hitting the garbage bag, the garbage bag rotates while bending.
Only the garbage bag can be broken, and the garbage in the garbage bag can be loosened without destroying the garbage in the garbage bag.

The linear member 30 is not limited to a wire.
Any material that can break the garbage bag by rotation, such as a plastic material, may be used.

The garbage in the garbage bag thus broken by the bag breaking machine 1 is discharged from the garbage discharge port 14 to the sorting conveyor 3, where the operator can make an aluminum can, a steel can, or a bottle by the sorting conveyor 3. Sort reusable items such as.

Further, a sorting machine for automatically sorting aluminum cans, steel cans, bottles and the like may be connected to the trash discharge port 14 of the bag breaking machine 1 so that this sorting may be automatically performed. .

[0022]

As described above, according to the present invention, the garbage bag is hit by rotating the flexible linear member, thereby breaking the garbage bag. Only the garbage bag can be broken without destroying the garbage, and the garbage bag put into the storage container can be reliably and smoothly broken. In particular, in the case where a garbage bag whose position changes as needed due to transportation in the drum is broken in the drum, a plurality of garbage bags may overlap in the drum, or may be transported to the vicinity of the top and fall down. The distance between the tip of the linear member and the garbage bag always changes, but in the present invention, since at least two or more types of linear members having different lengths are protruded, an appropriate number of the garbage bags move. Can be prevented from hitting the garbage bag more than necessary or conversely, and the garbage bag can be evenly broken.
