The screen plate has a discharge hole, and is crushed finely by the rotary crushing body 9, and the crushed material is discharged below the discharge hole of the screen plate.
[0010]
A discharge conveyor 11 for discharging the crushed material that has been crushed by the crusher 4 and discharged downward is provided below the crusher 4 at the lower part of the machine base 2 and extends obliquely upward from here. It reaches substantially the same height as the upper end position, and is held by the machine base 2 by the holding arm 12 at the intermediate portion. As shown in FIG. 3, the discharge conveyor 11 includes left and right frames 13 that are bent at a plurality of locations and warped upward. A tail pulley 14 is provided on the lower end side of the left and right frames 13, and left and right A head pulley 15 is provided on the discharge end side that is the upper end side of the frame 13, and a conveyor drive motor 16 is attached to the head pulley 15. The height of the head pulley 15 is substantially the same as the upper end position of the crusher 4 provided on the machine base 2, that is, the maximum height. An annular belt 17 is attached from the tail pulley 14 to the head pulley 15, and a large number of V-shaped protrusions 18 are provided on the surface of the belt 17, so that the crushed material on the belt 17 is reliably conveyed forward. I am doing so. Further, a plurality of belt support roller groups 20 are arranged between the tail pulley 14 and the head pulley 15 so as to support the belt 17. As shown in FIG. 4, the supporting roller group 20 is composed of three rollers 21 and 22 arranged to the left and right, with the central roller 21 being horizontal and the left and right rollers 22 being inclined to form a belt 17. The crushed material on the belt 17 is prevented from falling from the left and right sides by raising the left and right sides.
[0011]
Further, a dustproof sheet 24 is attached to the upper side of the discharge conveyor 11 via a plurality of frames 23 so as to cover the entire upper side of the belt 17 so that the crushed material on the belt 17 is blown away by the conveying speed, wind, and the like. Is prevented.
[0012]
And the scattering prevention cover 25 which prevents scattering of a crushed material is rotatably attached to the discharge end side of the discharge conveyor 11. As shown in FIG. 5, the scattering prevention cover 25 has a bucket shape in which a lower side is largely opened from left and right side plates 26 having a substantially triangular shape and a top plate 27 bent along the edges of the left and right side plates 26. In addition, the arm 28 is fixed to one end of each of the left and right side plates 26 so as to cover the discharge end side of the discharge conveyor 11 from above. On the other hand, as shown in FIGS. 6 and 7, columnar supports 31 are erected on the left and right discharge ends of the left and right frames 13 of the discharge conveyor 11, and a rotation mechanism 32 is provided on the upper ends of the left and right supports 31. And the rotation mechanism 32 is a pin 33 directed to the left and right that is fixed to the upper end of the support 31. Then, by attaching the arms 28 of the scattering prevention cover 25 to the pins 33 of the rotation mechanism 32, the scattering prevention cover 25 rotates via the rotation mechanism 32. Further, in the frame body 23 attached to the discharge end side of the discharge conveyor 11, the top plate 27 of the rotated anti-scattering cover 25 comes into contact, and the anti-scattering cover 25 further rotates downward. It comes to play the role of a stopper to avoid. On the other hand, the stopper body 34 is also attached to the outermost end portion on the discharge end side of the discharge conveyor 11 so that the scattering prevention cover 25 hits, thereby holding the scattering prevention cover 25. Although the rotation of the scattering prevention cover 25 is not shown, it may be manually operated by a string or the like, or may be rotated by a hydraulic motor or an actuator of a hydraulic cylinder. Further, in the rotation mechanism 32, a hinge or the like may be used instead of the pin 33.
[0013]
By attaching the anti-scattering cover 25 to the discharge end side of the discharge conveyor 11 in this manner, the crushed material crushed by the crusher 4 is lower than the discharge end side of the discharge conveyor 11 when crushing wood and the like. When the paper is dropped to the outside and discharged to the outside, the crushed material on the belt 17 can be covered with the anti-scattering cover 25 on the discharge end side of the discharge conveyor 11, and the crushed material is belted by the conveying speed, wind, etc. 17 can be prevented from being blown off from above. As a result, the crushed material can be reliably stacked at a predetermined position on the ground from the discharge end side of the discharge conveyor 11. Alternatively, the crushed material can be reliably loaded onto the truck bed from the discharge end side of the discharge conveyor 11.
[0014]
On the other hand, when the anti-scattering cover 25 is rotatably attached, when the anti-scattering cover 25 is not necessary, for example, when transporting the wood crushing apparatus on a truck bed, the anti-scattering cover 25 is provided. Rotate to the state shown by the two-dot chain line in FIG. 6 so that the scattering prevention cover 25 does not jump upward from the upper end of the discharge conveyor 11 on the discharge end side. This prevents the maximum height of the wood crushing device from becoming high, so that, for example, when transporting the wood crushing device on a truck bed or the like, the transport height restriction can be cleared, and the transportability Can be greatly improved.
[0015]
In addition, since the scattering prevention cover 25 is rotatably attached in this way, the upper end on the discharge end side of the discharge conveyor 11 can be set to the limit of the transport height limit, and the upper end on the discharge end side of the discharge conveyor 11 can be set. By making the height as high as possible, the crushed material can be piled high at a predetermined place during the crushing operation. This eliminates frequent movement of the wood crushing apparatus, and can improve work efficiency during crushing work.
[0016]
In the embodiment described above, the crushing device was a wood crushing device that crushes wood or the like and treats it as a crushed material, but is not limited to this, and other crushing devices such as, for example, A crushing device or the like for crushing unnecessary concrete may be used.
