<p><P>PROBLEM TO BE SOLVED: To efficiently suck and remove unnecessary trash from among construction waste. <P>SOLUTION: A suction regulating device 23 is provided at an apparatus 19 for removing trash from among construction waste W (scrap wood W) which moves the scrap wood W crushed and laid on a screen 17 in order to reutilize the scrap wood W after crushing relatively in one direction toward a suction hood 25 and which sucks and removes the trash from among the scrap wood W by the suction hood 25. The suction hood 25 is provided so that height from a screen surface can be freely changed in a vertical direction and is driven upward and downward by a suction hood vertically driving gear 61. A scrap wood height detector 63 provided in front of the suction hood 25 detects that height of the scrap wood W is at or above avoidance height S established in advance. According to this detection signal, a controller 65 gives the suction hood vertically driving gear 61 a directive to raise the suction hood 25 to the avoidance height S and a directive to lower the suction hood 25 to an original position after the scrap wood W passed the suction hood 25. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
