  Next, an embodiment of the present invention will be described.

  FIG. 1 is a diagram showing an overall configuration of the crushing apparatus, and FIG. 2 is an enlarged view of a part A in FIG.

  As shown in these drawings, the crushing device 1 includes a compression conveyor unit 2 that sandwiches and crushes a vinyl chloride pipe 4, and a shredding unit that further shreds fragments crushed by the compression conveyor unit 2. It has.

  The compression conveyor section 2 includes a loop-shaped upper compression conveyor 20 and a lower compression conveyor 25. The vinyl chloride pipe 4 is securely attached to the outer peripheral surfaces of the upper compression holder 20 and the lower compression 25. Protrusions 29 are provided for gripping and preventing lateral displacement with respect to the direction of travel of the conveyor.

  The lower compression conveyor 25 is supported on its inner peripheral side by a drive support shaft 27 provided on the shredded portion 3 side and a support shaft 26 provided on the input side (left side in the figure) of the vinyl chloride pipe 4. Has been. A lower conveyor motor 28 is connected to the drive support shaft 27 so that the lower conveyor motor 28 moves the upper surface of the lower compression conveyor 25 (upper compression conveyor 20 side) to the shredder 3 side. Driven.

  The upper compression conveyor 20 has a support shaft 23 provided on the shredder 3 side, a support shaft 21 provided on the input side of the vinyl chloride pipe 4, a support shaft 21 and a support shaft 23 on the inner peripheral side thereof. And a drive support shaft 22 provided between the two. An upper conveyor motor 24 is connected to the drive support shaft 22, and the upper conveyor motor 24 causes the lower compression conveyor 20 lower surface (lower compression conveyor 25 side) to face the shredder 3. Driven in the forward direction.

  The upper compression conveyor 20 is supported by the drive support shaft 22 and the support shaft 23 such that the lower surface thereof is inclined with respect to the upper surface of the lower compression conveyor 25, and The support shaft 21 and the drive support shaft 22 are supported so as to have a second inclination with respect to the upper surface of the lower compression conveyor 25.

  The first inclination is set such that the opening angle with the upper surface of the lower compression conveyor 25 is smaller than that of the second inclination.

  Moreover, the upper compression conveyor 20 and the lower compression conveyor 25 sandwich and crush the vinyl chloride pipe 4 between the first inclined portion of the upper compression conveyor 20 and the upper surface of the lower compression conveyor 25. It is arranged in a positional relationship that can be crushed.

  Thus, when the vinyl chloride pipe 4 is inserted between the upper compression conveyor 20 and the lower compression conveyor 25, the first inclined portion of the upper compression conveyor 20 and the upper side of the lower compression conveyor 25 are provided. The vinyl chloride pipe 4 is crushed and crushed by the surface, and is sent to the shredded portion 3 side as a pipe piece 4A.

  The rotations of the upper compression conveyor 20 and the lower compression conveyor 25 are controlled at their respective speeds or operations by the rotation speeds of the upper conveyor motor 24 and the lower conveyor motor 28. Therefore, depending on the setting, for example, the rotation speed of the upper conveyor motor 24 and the lower conveyor motor 28 can be the same, different, or intermittently operated. Thereby, for example, it is possible to apply a twisting force other than the pressure to crush the vinyl chloride pipe 4 due to the difference in rotational speed between the upper compression conveyor 20 and the lower compression conveyor 25.

  As shown in FIG. 2, the shredding portion 3 includes a stage 32 disposed so as to be substantially flush with the upper surface of the lower compression conveyor 25, a press plate 30 provided above the stage 32, It comprises a shredding cutter 33 provided at the end of the stage 32 facing the compression conveyor section 2.

  The shredding cutter 33 is supported by a support member (not shown) via a cutter drive cylinder 34 and moves up and down by the cutter drive cylinder 34.

  As a result, the pipe piece 4 </ b> A sent from the compression conveyor unit 2 to the stage 32 is pressed by the presser plate 30 urged to the stage 32 by the presser spring 31.

  The pipe piece 4 </ b> A that is fed from the compression conveyor unit 2 and protrudes from the end of the stage 32 on the shredding cutter 33 side is shredded by the shredding cutter 33.

  In the present embodiment, the upper conveyor motor 24 and the lower conveyor motor 28 constitute a drive unit in the present invention.

  In this embodiment, the vinyl chloride pipe 4 is reliably sandwiched and crushed by the upper compression conveyor 20 and the lower compression conveyor 25 arranged in a substantially fan shape when the vinyl chloride pipe 4 is inserted. Thus, the introduced vinyl chloride pipe 4 can be efficiently crushed without being rebounded.

  Moreover, since it is a method of crushing and crushing, it can crush more efficiently than crushing by cutting using a rotary cutter or the like.

  By chopping the pipe piece 4A crushed and sent out by the compression conveyor section 2 with the chopping section 3, it is possible to obtain a fine pipe piece that is easier to process.

  Furthermore, by setting the rotational speeds of the upper compression conveyor 20 and the lower compression conveyor 25 to different speeds, a twisting force can be applied in addition to the crushing pressure on the vinyl chloride pipe 4, and the destructive force on the vinyl chloride pipe 4 can be further increased. Can be increased.

  Further, by pressing the pipe piece 4A sent out from the compression conveyor section 2 with the inclined pressing plate 30, the pipe piece 4A can be smoothly sent out to the shredding cutter 33 side while being pressed down.

  Further, the crushing device has a simple structure and can be configured compactly.

  In addition, the noise at the time of crushing can be suppressed by providing the cover which covers the conveyor part 2 for compression which crushes the vinyl chloride pipe 4. FIG.

  Further, the crushing apparatus of the present invention is arranged in the horizontal direction in the figure (that is, the pipe piece 4A is fed from the left side to the right side in the figure by the upper compression conveyor 20 and the lower compression conveyor 25 and is shredded. However, the arrangement direction is not limited to this, and the arrangement direction may be perpendicular to the vertical direction or inclined in various directions with various angles.

  Further, in the above embodiment, the shredding cutter 33 is used to shred the pipe piece 4A. However, the shredding cutter 33 is not limited to this. For example, a rotary blade is provided on the stage 32, and this is rotated. By doing so, the pipe piece 4A may be shredded.

  Further, in order to securely grip the vinyl chloride pipe 4 and prevent it from being displaced with respect to the traveling direction of the conveyor, a projection 29 is provided on the outer peripheral surfaces of the upper compression chamber 20 and the lower compression 25 as so-called gripping means. However, this may be anything as long as it securely grips the vinyl chloride pipe 4 and prevents it from shifting with respect to the traveling direction of the conveyor, and is not particularly limited to a protrusion. Moreover, the shape and size are not particularly limited, and any shape may be used.
