<P>PROBLEM TO BE SOLVED: To provide a suction wind power type sorting device which can sort a material by sucking it by a stable prescribed suction force. <P>SOLUTION: A first plate member 20 covering the entire surface of a suction port 121a is fixed to the suction port 121a of a suction frame body 121. The first plate member 20 is arranged so as to be parallel or substantially parallel with a shoot member 170 at the lower end of an inclined screen 112. In the first plate member 20, a plurality of annular holes 21 having the same diameters are uniformly formed at the entire surface of the first plate member 20. Accordingly, since air sucked from the suction port 121a passes through the plurality of holes 21 which are uniformly formed at the entire surface of the first plate member 20, a flow rate becomes constant over the entire surface of the suction port 121a, and a layer flow is formed. Thereby, the suction force becomes constant over the entire surface of the suction port 121a, and the stable suction force can be obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
