Description

  The present invention relates to a crushing apparatus that can efficiently crush old tires generated in large quantities.

  In today's automobile society, the disposal of used tires that are disposed of in large quantities is a major environmental problem, but it is often used as a fuel for one of these treatment measures. Compared to heavy oil and coal, the cost is slightly lower and the combustion efficiency is never worse. In this case, however, a large tire cannot be used as it is and must be cut into small pieces. In addition, when transporting old tires, they are bulky as they are and are not easy to store.

  Therefore, the finely cut tire chips can be handled in the same manner as the transportation and storage of coal, and the use of old tires as fuel becomes convenient. In order to cut the old tire finely, the applicant has previously obtained a registration of a utility model regarding “cutting line device for old tires” (utility model registration No. 2115454).

  This device is composed of a supporting roller that lifts and lowers a tire, a cutter that has anti-slip rollers formed on both sides, and a wheel-cutting device that supports a guide roller on both sides of the cutter. A conveyor for placing the tire pieces that have been cut on the base of the cutting device, and a conveyor for feeding the tire pieces that have been placed on the base to the receiving section by carrying in; a feed member is attached to the conveyor chain of the conveyor In addition, a cutting device in which a plurality of blades are radially attached to a blade base that moves up and down by the action of a hydraulic cylinder above the housing portion, and a stripper having a hole through which the blade is inserted is suspended below the blade base. Further, it comprises a carry-out device for carrying out a tire cut piece (tire chip) cut by the cutting device. "

  A conventional cutting device is provided with a housing portion that accommodates a tire piece that has been cut, and a plurality of blades are radially attached to a blade base that is lifted and lowered by the action of a hydraulic cylinder above the housing portion, and below the blade base. Is configured by suspending a stripper having a hole through which a blade is inserted, and is a device that can cut a tire piece placed on a housing portion to a certain degree by dropping the blade. However, since the plurality of blades of this apparatus are arranged radially, the tire chip to be cut is relatively large in the form of a triangle or a trapezoid, and the shape and size of the tire chip are not uniform.

  An “old tire cutting device” according to Japanese Patent Application Laid-Open No. 2010-184330 is a device for finely cutting an old tire placed on a mounting table by lowering a cutting blade with a ram. That is, a plurality of cutting blades are attached to a fixed plate at a predetermined interval in a certain direction, the fixed plate is attached to a rotary table provided on the lower side of the ram, and the rotary table can be rotated by a motor. Further, the rotary table is provided with a stripper in which a groove for fitting the cutting blade is formed and a spring force is applied so that the lower surface thereof is positioned at least below the tip of the cutting blade.

However, these conventional old tire cutting devices are methods in which one tire is placed on a table and press-cut, and therefore the number of cuts per unit time is limited. In addition, there is a problem in that a cut piece larger than a predetermined size remains even once cut.
"Cutting line equipment for old tires" related to utility model registration No. 2115454 "Old tire cutting device" according to JP 2010-184330 A

  As described above, the conventional used tire cutting apparatus has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a crushing apparatus that can efficiently crush a large number of old tires in a short time and can crush them to a predetermined size or less.

The old tire crushing apparatus according to the present invention has a large rotating drum, and a plurality of holes penetrates the rotating drum. The rotating drum is provided with a crusher, and the crusher crushes old tires into pieces of a predetermined size. Although the specific structure of the crusher is not limited, it is generally a crusher having two rotating blade groups that rotate in opposite directions, and each blade of the rotating blade group is arranged alternately, and each rotation The blade group is rotationally driven by a separate motor.
The old tire is finely crushed between the rotating blades rotating in opposite directions, and the crushed pieces fall from holes provided on the outer periphery of the drum. And it has the discharge conveyor which discharges the crushed piece which fell.

  However, there are cases where the rotating blade of the crusher does not immediately crush it to a predetermined size or less, and when a large crushing piece falls into the drum, it is not discharged from the hole formed in the drum. Therefore, a large crushed piece enters a hopper attached to the inner periphery of the drum, rises with the rotation of the drum, falls from above, is again put on the crusher, and is crushed. That is, in the crusher, the crusher is repeatedly put into the crusher until the size is discharged through the hole of the drum.

The discharge conveyor extends from the bottom of the drum so that debris discharged from the holes provided in the drum can fall onto the discharge conveyor and be carried on the conveyor. One carry-in conveyor is used to supply old tires to be crushed to the crusher. For this purpose, the carry-in conveyor is arranged so that it can be put into a hopper mounted on one side opening of the rotary drum. Here, the specific forms and structures of the carry-in conveyor and the discharge conveyor are not limited.
On the other hand, since the crusher is arranged inside the rotating drum, it is arranged so that the rotating drum can be moved when the crusher is maintained and inspected.

The old tire crushing apparatus according to the present invention is convenient for use in fuel or the like because old tires are crushed into small pieces by a crusher, that is, pieces of a predetermined size or more are not discharged. Is good.
In the present invention, a crusher is provided inside a large rotating drum, and old tires carried by a carry-in conveyor are finely crushed by the crusher, and only crushed pieces having a predetermined size or less are discharged from holes provided on the outer periphery of the drum. Then, it is carried out on the carry-out conveyor.

  Since the crushed pieces that are not crushed by the crusher do not pass through the holes, they enter the hopper provided on the inner periphery of the drum, rotate, and are crushed again by the crusher. It is configured to be applied to the crusher any number of times until it becomes a crushed piece of a predetermined size or less. And, the crushing device of the present invention can put the old tire on the carry-in conveyor and put it into the hopper attached to the opening on one side of the rotating drum, so that the old tire can be crushed continuously and carried out by the carry-out conveyor, Many old tires can be efficiently crushed in a short time.
