1, a pinion gear 32 with an output shaft thereof, a rotor-equipped gear 33 that meshes with the pinion gear 32, and an idler gear 34 between adjacent rotor-equipped gears 33, 33. The four rotors 20, .. are all rotated in the direction of arrow A. In addition to this, the rotary drive device is also configured to span a chain between a sprocket with a rotor and a sprocket with a motor, and intervene an sprocket for idling to rotate the rotor in the direction of arrow A.

Each rotor 20 has an angular shaft 21 of square cross section having a gear 33 fixed to one end thereof, and a regular hexagonal hole (not limited to this, polygonal or Large-diameter ring 24 made of hard rubber (or made of soft plastic, cast iron or various alloys) that has splines or a circle with a key and is arranged so as to be intertwined with those adjacent in the vertical direction And a small-diameter wheel body 28 projecting from one side of the large-diameter wheel body boss portion 25 so as to be located between the large-diameter wheel bodies 24, 24, and a rotor end at the rotor end for the above-mentioned interlocking state. It is composed of an end small-diameter wheel body 28 'that is appropriately provided. The large-diameter wheel 24 and the small-diameter wheel 28 form an integrated merged wheel 23. The large-diameter wheel body 24 has a wheel body portion 26 around the boss portion 25 thereof, and is suitable for sorting work of slag and crushed stone.

The ring portion 26 of the large-diameter ring 24 is formed by the boss portion 25.

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. This rotor 20
Is formed by combining a plurality of merging wheels 23 integrally formed with a small-diameter wheel body 28 on an extension portion of a boss portion of a large-diameter wheel body 24 on a central angle shaft 21. It is possible to partially replace the merging wheel body 23 in a portion that is frequently worn and is heavily worn, and maintenance costs can be kept low. Also, a large rotor can be manufactured.
