[0006]

[Operation] The crushed pieces crushed by the crusher 3 are discharged to the outside of the vehicle body 1 by the discharge conveyor 7.
The iron-based crushed pieces were removed by the magnetic separator 8 while being transported by
Since the crushed pieces discharged by the discharge conveyor 7 are only non-ferrous materials, they can be easily reused.

[0007]

[Examples] As shown in FIGS. 1 and 2, a vehicle body 1, a pair of left and right traveling bodies 2 and 2 attached to the vehicle body 1, a crusher 3 attached to one side of the vehicle body 1 in the front-rear direction, A power source 4 attached to the other side of the vehicle body 1 in the front-rear direction, a cover body 5 for covering the power source 4, a hopper 6 attached on the cover body 5, and one side portion of the vehicle body 1 in the front-rear direction. The discharge conveyor 7 is mounted between the pair of left and right traveling bodies 2 and 2 so as to be vertically swingable, and the magnetic separator 8 is mounted on one side of the vehicle body 1 in the front-rear direction. The discharge side of the discharge conveyor 7 is vibrated. A formula screen 9, a secondary belt conveyor 10 and a tertiary belt conveyor 11 are installed on the ground.

As shown in FIGS. 3, 4, and 5, the discharge conveyor 7 connects a pair of left and right frames 20 and 20 with a space therebetween, and a drive pulley 21 and a driven pulley 22 are provided between the frames 20. , The conveyor motor 2 provided on the frame 20 while winding the belt 23 around them
4, the drive pulley 21 is directly driven, one end of the frame 20 in the longitudinal direction is located below the flexible discharge guide 25 provided at the outlet 3b of the crusher 3, and The lower bracket 1a is supported by a pin 26 so as to be vertically swingable, and a cylinder 28 is pivotally mounted between a support frame 27 attached to the vehicle body 1 and the frame 20.

The magnetic separator 8 has a main body 30 and a drive pulley 31.
And a driven pulley 32, the magnetic belt 33 is wound around both pulleys, and the drive pulley 31 is driven by the magnetic separator motor 34.
Is configured to be driven. That is, the main body 30 becomes a rectangular frame by the pair of first frame members 30a, 30a facing each other and the pair of second frame members 30b, 30b facing each other, and the first frame member 30a and the drive pulley 31 via the bracket 30c. A driven pulley 32 is rotatably supported, and a magnetic separator motor 34 is attached to one bracket 30c. An upper bracket 30d (one end portion in the width direction of the magnetic belt) of one first frame member 30a of the main body 30 is supported by a bracket 35 on the bracket 27a near the base end of the support frame 27 so as to be vertically swingable. The upper bracket 30e (the other end in the width direction of the magnetic belt) of the other first frame 30a of the main body 30 and the bracket 27b on the upper end of the support frame 27.
And a stretchable member 36, for example, a first screw rod 36a and a second screw rod 36b that are mutually reverse screws, and first and second nuts screwed to the first and second screw rods 36a and 36b. Three
6c and 36d and their first and second nuts 36c and 36d
A turnbuckle composed of a member 36e for connecting is connected pivotally.

As a result, the magnetic separator 8 is arranged above the discharge conveyor 7 and rotatably in the direction in which the magnetic belt 33 crosses the discharge conveyor 7, and the other end of the magnetic belt width direction is expanded and contracted by expanding and contracting the expansion / contraction member 36. When the portion swings up and down and the angle of the discharge conveyor 7 with respect to the horizontal changes, the magnetic belt 3
3 can be made parallel to the discharge conveyor 7.

The vibrating screen 9 is the discharge hopper 4.
In addition to mounting the screen 41 inside 0, a vibration generator equipped with a vibration generating motor 42 is attached to the discharge hopper 40, and the discharge hopper 40 is mounted on a frame 43 installed below the discharge conveyor 7 via an elastic material 44. The crushed pieces fall on the screen 41, the small crushed pieces fall on the secondary belt conveyor 10 through the screen 41, and the large crushed pieces fall on the tertiary belt conveyor 11 along the screen 41. To do.

FIG. 6 shows a second embodiment, in which an elastic member 36, for example, the above-mentioned turnbuckle is pivotally connected to the upper bracket 30d of the main body 30 of the magnetic separation material 8 and the bracket 27a near the base end of the support frame 27. The magnetic separation material 8 can be moved up and down at both widthwise ends of the magnetic belt 33.

In this way, the angle of the magnetic belt 33 with respect to the horizontal can be adjusted, and the magnetic belt 33 can be moved in parallel in the vertical direction, so that the angle with respect to the discharge conveyor 7 can be adjusted and the magnetic belt 33 can be adjusted in parallel with the discharge conveyor 7. You can adjust the distance.

[0014]

The crushed pieces crushed by the crusher 3 are discharged to the outside of the vehicle body 1 by the discharge conveyor 7. The iron-based crushed pieces are removed by the magnetic separator 8 while being conveyed by the discharge conveyor 7. Since the crushed pieces discharged by the discharge conveyor 7 are only non-ferrous materials, they can be easily reused. In addition, by combining the vibrating screen 9 and the secondary and tertiary belt conveyors 10 and 11, the crushed pieces can be separated into iron-based crushed pieces, large non-ferrous crushed pieces, and small non-ferrous crushed pieces, and reusable remarkably. It will be easier to do.
