Rotate in the direction of arrow A. In addition to this, as the rotation drive device, a chain is stretched over a sprocket with a rotor and a sprocket with a motor, and an idling sprocket is appropriately interposed to rotate the rotor in the direction of arrow A.

As shown in FIGS. 3 and 4, each rotor 20 has an angular axis 2 of square cross section having a gear 33 fixed to one end thereof.
1 and a regular hexagonal hole (not limited to this, which may be a polygonal shape or a circular shape) that fits into the square shaft 21 and are arranged so as to be in a state of being intertwined with each other in the longitudinal direction. The large-diameter ring body 24 made of rubber or soft plastic, and the large-diameter ring body boss portion 2 so as to be located between the large-diameter ring bodies 24, 24.
5 is composed of a small-diameter ring 28 protruding from one side and an end small-diameter ring 28 'in the interlocking state. The large-diameter ring 24 and the small-diameter ring 28 form a merged ring 23. The large-diameter ring member 24 has a plurality of protruding members 26 (12 in this embodiment) that are protruded and curved so as to retract from the boss portion 25 in the rotational direction A, and a front protruding member 26 that is adjacent in the rotational direction.

Heavy ropes, strings and wires are connected to the protruding body 2 by the connecting plate 27 between the protruding bodies 26 and 26.
Are prevented from being entangled with each other, and are successively inherited or kicked out in the transport direction by the tip of the protruding body 26 or the outer edge of the connecting plate 27. In addition, even if the object to be processed is a lump, the object is beaten at the tip of the protruding body 26 to be unraveled, and a large amount is continuously and efficiently sorted. Further, the connecting plate 27 not only prevents the cord-like object from being inserted therein, but even if it is wound, the connecting plate 27 is immediately separated by the centrifugal force due to the inclined outer edge.

The projecting body 26 of the large-diameter wheel body 24 has a boss portion 25.
Is formed so as to be thicker and gradually thinner toward the outer peripheral portion, so that the entire large-diameter ring 24 has a conical curved surface with both sides almost low like an abacus ball, and the large-diameter ring of the adjacent rotor is formed. It is easy to get into and out of the gap 24, that is, the sieve mesh G through which the sieve mesh material passes relatively easily is formed, and the efficiency of the sorting operation can be improved. Also, the large diameter wheel 2
The connecting plate 27 of No. 4 is formed so that the wall thickness thereof gradually becomes thinner toward the rear in the rotation direction, and partial front surfaces are formed on both sides of the front surface of the projecting body 26. It has an air discharge capacity closer to that of a pump impeller. The rotor 20 is formed by combining a plurality of merging wheels 23 in which a small-diameter wheel body 28 is integrally formed in an extension portion of a boss portion of a large-diameter wheel body 24 on a central angle shaft 21 and is provided on a supply side or a central portion. It is possible to partially replace the merged wheel body 23 in a portion where the sorting work is performed well and wear is heavy, and the maintenance cost can be kept low. Also, a large rotor can be manufactured.

The rotor 20 is also constructed by alternately forming a plurality of large-diameter wheels 24 and small-diameter wheels 28 integrally, and can be manufactured in a small roll shape at low cost. Further, in the large-diameter wheel 24, a plurality of protrusions of various shapes such as hemispheres are provided in a radial direction on one surface of each of the protrusions 26, and the other surface is made a flat surface to make the sieve mesh G fine. Alternatively, a configuration in which a wind that causes a light object to slide on the rotor 20 may be generated. In addition, if a spacing piece is added or the length of the small-diameter ring body 28 is changed, the distance between the adjacent large-diameter ring bodies 24 changes, and the same effect as changing the size of the sieve mesh G is obtained. You can Further, it is possible to provide a ridge for generating wind on the outer peripheral surface of the large-diameter wheel body 24, or to appropriately provide an undulation 29 for generating wind on the outer peripheral surface of the small wheel body 28 as shown in FIG.

In addition to the above, the large-diameter wheel body 24 and the small-diameter wheel body 28 may be molded separately, and the material is not limited to rubber or plastic, and may be metal or wood.

In the waste sorter 1 of this embodiment, a relatively strong wind is generated toward the discharge side during operation, and together with the connecting plate 27, a radio cassette tape, a video cassette tape, a nylon string, or the like is used. If it is light, it can be floated without being completely wound up and discharged, and a bundle of ropes and wires is successively taken over by the projecting body 26 of the large-diameter ring body 24 and the connecting plate 27 and discharged. Further, even if wastes or other substances having a high water content are mixed in the waste W, they can be dropped downward without causing clogging, and this can be used for sieving compost. When the rotation speed of the rotor 20 is increased, the sieve mesh G formed by the side surfaces of the adjacent large-diameter wheel bodies 24, 24 and the peripheral surface of the small-diameter wheel body 28 becomes relatively fine, and when the rotation speed is decreased, the sieve mesh G relatively becomes. The sieve mesh G becomes coarse.
Further, the sorting machine 1 has a structure in which clogging and breakage are unlikely to occur, and can continuously sort a large amount of construction waste, household garbage, restaurant leftovers, and the like into two types with low noise and low vibration. If the crushing process is performed before the waste is put into the sorting machine 1, the processing after sorting can be performed immediately.
