The sorting machine 1 shown in FIGS. 1 and 2 is the most basic horizontal type, and is a rectangular frame 10 laid on a conveyor belt C2 for carrying out small and medium sized objects w1 and w2.
And in the frame 10 in the same plane in the same plane and horizontally in the same plane in the vertical direction from the input side of the object to be processed to the discharge side of the selected large object w3 (indicated by arrow A).
4 rows of rotors 20, which are rotatably supported by
.. and a discharge portion 16 for the large object w3 in the rotation direction A.

On the loading side of the frame 10, a conveyor C1 for loading a to-be-processed object W such as a slag or crushed stone from above is continuously provided, and on the discharging side, a ramp way 16 for discharging a large object w3 is connected. Between the side walls 11
The rotor 2 is rotatable by a bearing 11a mounted thereon.
0 and a rotary drive device 30 is arranged outside one of the side walls 11. The rotation driving device 30 is
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.
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. 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.

The rotor 20 is constructed by alternately forming a plurality of large-diameter wheels 24 and small-diameter wheels 28 on the mandrel shaft, and can be manufactured in a small roll shape at low cost. Further, as shown in FIG. 5, the large-diameter wheel 24 has an undulation 27 that easily loosens the lumps to facilitate the selection work of shredder dust or the like, and causes a wind that causes a lightweight object to slide on the rotor 20. Can be appropriately provided on the outer peripheral surface of the wheel body portion 26, and the projections 26A that generate wind on the side surfaces can be appropriately provided, and the undulation 29 can also be provided on the outer peripheral surface of the small wheel body 28.

Also acts to adjust the size of the sieve mesh G.

The sorter 1 of this embodiment not only sorts slag, crushed stone, and shredder dust, but also sieves bark and compost with a high water content, and wets with a high water content such as soil and sewage. Even if it is mixed in the object W, it can be dropped downward without causing clogging, and even if a light object such as a video cassette tape or nylon string is mixed, it can be ejected without wrapping, rope or The bundle of wires is also inherited one after another by the large-diameter wheel 24 and discharged. 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 object to be processed is put into the sorting machine 1, the processing process after the sorting can be performed immediately.

(1) A large-diameter wheel and a small-diameter wheel, which are wheels having at least two kinds of diameters in the lateral direction of each rotor, are alternately interdigitated with those wheels of an adjacent rotor to form sieve meshes. Are arranged so that the objects to be treated can be sorted by the sieve mesh into those passing through the sieve mesh and those which do not pass through while being sent from the supply side to the discharge side of the residue on the rotor. Since the sieve mesh is formed between the large-diameter ring body and the small-diameter ring body of the rotating adjacent rotors, the soil and the wet food, which are wet or wet,
Even if it is instantly clogged by compost, it is always cleaned and new sieve mesh is always formed so that it does not clog. (2) In addition, the large-diameter wheel body has a narrow peripheral surface in addition to the side surface of the conical curved surface, and the tire having a small-diameter wheel body integrally formed in the extension portion of the boss portion of the tire. It is durable to hard and square objects to be processed such as slag and crushed stone, and can withstand continuous operation for a long time. It is wrapped with rope, string, tape, and entangled with shredder dust. Can be discharged without being affected by Even if it is a lump, the object to be treated is beaten and unraveled while moving between the large-diameter wheels, and a large amount of the object to be treated can be continuously and efficiently selected. Further, since the rotor is constructed by combining a plurality of merging wheels on the central axis, it is possible to partially replace the parts that are frequently subjected to the sorting work and are heavily worn, so that the maintenance cost can be reduced.

(3) In the sorting machine rotor according to the second aspect, the conical curved surface of the large-diameter ring body is a curved surface of a low cone, and forms a sieve mesh through which a sieve mesh passing product passes relatively easily. As a result, the sorting efficiency can be improved and the durability can be maintained.
