Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method and apparatus for shredding motor vehicle tires, particularly old tires.

<Conventional Technology> In the modern age of automobiles, a large amount of worn out and unnecessary tires are generated.

A small amount of old tires are used as cushioning material for ships, but there is no way to effectively utilize large amounts of old tires.

Old tires have a well-known circular shape, so if left unattended, they look unsightly and spoil the beauty of the surrounding area, and are bulky and require a large space to store.

Therefore, old tires are incinerated, but since they are not in a shape that is easy to incinerate, it takes a lot of effort to incinerate them.

<Problem that the invention seeks to solve> After all, in the past, it has been difficult to dispose of old tires.

The reason why it is difficult to dispose of old tires is due to the shape of the tires.

Old tires, in their original circular shape, have a limited range of use as cushioning materials, are bulky and inconvenient to store and transport, and are also difficult to incinerate and dissolve.

If old tires are cut into strips, the strips can be glued together to form rubber pieces of a desired shape, expanding the scope of their use as cushioning materials. Moreover, if it is made into small pieces, its bulk will be significantly reduced, making it convenient for storage and transportation. Furthermore, it becomes easier to incinerate and dissolve.

In short, old tires are easier to dispose of if they are cut into small pieces.

However, the technology for cutting tires into small pieces seems not to be known.

An object of the present invention is to solve the conventional problems as described above.

Means for Solving the Problem> In order to achieve the above object, the present inventor conducted various experiments and surprisingly discovered that it is possible to cut tires into small pieces using the same principle as a meat grinder that grinds meat finely. I discovered that it is possible.

That is, in the present invention, a tire or a tire piece cut into several pieces is pressed against the plate surface of a contact plate having a large number of through holes, and a portion of the tire or tire piece is inserted into each hole of the contact plate. It is characterized by cutting the part of the tire or tire piece that protrudes into each through hole of the abutment plate by sliding the cutting edge of the knife on the tire abutment plate surface of the abutment plate. This is a method of cutting tires into small pieces.

In addition, in the present invention, a screw shaft is rotatably inserted into the feed tube, an input port is provided on the base end side of the feed tube into which tire pieces obtained by cutting the tire into several pieces are inserted, and the opening at the tip of the feed tube is , a contact plate with many through holes is attached, and a tire piece inserted into the input slot is pressed against the inner plate surface of the contact plate by rotation of the screw shaft, and a part of the tire piece is inserted into each of the contact plates. It has a structure that protrudes into the through hole.

A cutter is attached to the tip of the screw shaft, and the cutting edge of the cutter, which rotates as the screw shaft rotates, slides into contact with the inner plate surface of the contact plate, and a part of the tire piece protruding into each hole of the contact plate is inserted into the cutter. This is an apparatus for cutting tires into small pieces, characterized in that the tire is cut into pieces by the rotation of the tire.
