In the crushing and sorting plant C shown in the figure, the waste and scraps of scrap vehicles carried in by the waste collection vehicle are thrown into the crusher 61 by the conveyor 60, where they are crushed by, for example, a plurality of breakers, grinders and the like. . The crushed crushed material is thrown into the long material extracting device 63 by the conveyor 62.

8 to 10 show a concrete configuration of the long object take-out device 63. A rotary shaft 65 is provided near the end of the conveyor 62 in parallel with the head pulley 64 of the conveyor 62. A screw 66 is provided on the outer circumference of the rotary shaft 65. Below the head pulley 64 and the rotary shaft 65, a chute 68 that passes between the tip of the conveyor 62 and the rotary shaft 65 and receives a crushed material 67 of a normal size is provided. On the other hand, in front of the chute 68, a chute 70 that receives the long object 69 moved laterally by the screw 66 and discharges it laterally is provided.

With such a configuration, the crushed material 67 of a normal size among the crushed materials that has been conveyed by the conveyor 60 and crushed by the crusher 61 is, as shown in FIG. 7 and FIG. It passes between the tip and the rotary shaft 65, passes through a chute 68, falls onto a conveyor 71, and is sent to a magnetic separator 72. Further, when a long object 69 such as a wire or a round bar comes, it is placed on the rotating shaft 65 as shown in FIG. It is sent in the direction indicated by the arrow 10 and falls into the chute 70 for a long object to be taken out to a predetermined place.

[0006]

[Problems to be solved by the device]

 However, the above-mentioned conventional long object take-out device 63 still has the following problems to be solved.

That is, as shown in FIGS. 8 to 10, when the long objects 69 are transferred to the long object take-out device 63 in a state where the long objects 69 are arranged in substantially the same direction as the transfer direction of the conveyor 62, Since the long object 69 is vertically transferred between the spiral blades of the screw 66, the long object 69 can be taken out laterally in the width direction. However, when the long object 69 is transferred to the long object take-out device 63 in a state where the long object 69 is arranged in a direction substantially orthogonal to the transfer direction of the conveyor 62, the long object 69 is not connected to the end of the conveyor 62. It falls through the gap between it and the screw 66 as it is, passes through a chute 68 for receiving a crushed material 67 of a normal size, and then falls onto a conveyor 71, in which a long object 69 is mixed in a normal state. Since the crushed material 67 having a size is sent to the magnetic separator 72, it causes clogging of the crushed material in the magnetic separator 72.

The present invention has been made in view of the above circumstances, and it is possible to reliably perform long objects regardless of the arrangement state of the long objects in the waste transferred to the long object takeout mechanism. The object of the present invention is to provide a long-length object extraction mechanism in a sorting device that can take out from waste.
