[0009] Then, as shown in FIG.
A drive motor 7 is mounted on one of 4A and 4B, and an endless belt 8 driven by the drive motor 7 is hung on a driven pulley 9 exposed on the outer surface of the sorting box 2, and is driven by the driven pulley 9. A well-known vibration device located inside the separation box 2 is attached to the support shaft 9A. That is, as schematically shown in FIG. 2, the vibration device having the well-known structure includes the eccentric weight 10 supported by the support shaft 9 </ b> A. Vibration acceleration can be given in the vertical direction. Therefore, when the driven pulley 9 is rotationally driven by the drive motor 7, vibration is generated by the vibrating device, and the above-described vibration motion corresponding to the elastic coefficient of the suspension spring 5 is given to the entire separation box 2.

[0010] The coarse sieve 11 is internally be fractionated Daikatamari product x ₁ from the entered clay waste X fractionation box 2 is placed, the upper outlet 12 is opened to face to the coarse sieve 11 ₁ large chunk passed through
3 The Daikatamari product x ₁ is intended to be placed obliquely descending state toward the upper outlet 12 in a state positioned immediately below the hopper 3, as will be understood from FIG. 4, the outer diameter of about 5~8mm Plain weave the round bar in a grid,
Sift opening L according to the size of large lump x _{1 to be} sorted

The opening formed in the bottom wall of the sorting box 2 is covered with a parallel line sieve 15 which is inclined downward toward the lower outlet 14 on the right side wall of the sorting box 2. That is, the parallel line sieve 15 is composed of a plurality of piano wires or steel wires extending in the inclined direction. As can be understood from FIG. 4 shown in comparison with the coarse sieve 11, the sieve opening L of the coarse sieve 11 is changed. _It has an arrangement pitch P which is about a fraction of one.
Accordingly, the parallel line sieve 15 sifts the gravel pieces x ₂ contained in the clay waste X, discharges the gravel pieces x ₂ from the lower chute 16 connected to the lower outlet 14, and also outputs the parallel line sieves. soil was x ₃ comprising clay that has fallen from the sieve 15 is collected into the collecting hopper 17, which will be described in detail later.

[0012] The body frame 1, the collecting hopper 17 is opened the top towards the parallel line sieve 15 is fixed, soil product x ₃ containing the recovered clay in the collection hopper 17 is catching The paper is discharged from the lower opening of the collection hopper 17 to the outside of the machine, and is processed by a discharge conveyor or the like (not shown).

[0013] Since the fractionator clayey waste according to the illustrated embodiment has a structure as described above, clay waste X is in the following step, Daikatamari product x _1, gravels pieces x _2, clay fractionated as soil substance x ₃ comprising, it is landfilled in accordance with the respective purposes. That is, the sorting box 2 into which the clay waste X is charged from the charging hopper 3 is given a vibration acceleration in the vertical and horizontal directions by the vibrating device driven by the drive motor 7, so that the clay on the coarse sieve 11 is applied. Quality waste X
Soil was x ₃ containing gravel pieces x ₂ and clays of the coarse sieve 1

In the soil was x ₃ containing gravel pieces x ₂ and clay it is reliably separated. That is, since the parallel wire sieve 15 is formed of a piano wire or steel wire having a parallel shape, the clay on the parallel wire sieve 15 is elongated due to the vibration acceleration and the shape of the parallel wire sieve 15. Since it is cut and its adhesive strength is weakened, the parallel line sieve 15 is dropped below the parallel line sieve 15 without clogging. Further, a large gravel pieces x ₂ Particle size, parallel lines sieve 15
While staying on the upper side, the vehicle travels rightward along the parallel line sieve 15 and is discharged from the lower chute 16 to the outside.
