I can do it. Thus, it is possible to perform a sanitary operation while smoothly promoting the processing operation performed in each room without being hindered by debris. The dust sucked by the dust suction device 9a adheres to minute glass powder generated when the workpiece W is crushed, crushed paper pieces such as labels attached to the workpiece W, and the workpiece W. It is a material with a low specific gravity, such as attached mud.

Next, the configuration of each part of the crusher 1 will be described. First, the crushing chamber 4 and the crushing chamber 6 are provided with a crushing structure having a configuration to be described later in the inside thereof, and primary crushing for roughly crushing the workpiece W and crushing the crushed workpiece W further smaller. By continuously performing the secondary crushing in a plurality of stages, the edge of each crushed particle is formed while forming the crushed particles of a desired size, so that the crushed particles have a smooth surface without causing sharp edges. And the crushed granules selected by the sorting device 9 can be effectively used for various purposes.

Projected inward with different phases.

As shown in FIG. 4, the bottom wall 10 forms a stay allowance H by separating the curved inner peripheral surface from the outer peripheral locus of the tip of the crushing tooth 20 by a predetermined distance, and forms a stay allowance H before and after that. Steps 10a and 10b which are inclined in the direction are formed, and a projection (restriction surface) 10c which is inclined inward and protrudes inward is formed on the upper side of the discharge port 12 in the crushing direction. With this configuration, the bottom wall 10 constantly forms crushed particles or powdery fine crushed particles (hereinafter referred to as abrasive particles) generated during crushing of the workpiece W between the stepped portion 10b and the projection 10c in a layered manner by an amount of stagnation allowance H. Crushing teeth 20 and receiving teeth 21

Further, even if the step portion 10a is worn out by contact with crushed grains or abrasive grains, the stepped portion 10a has a thick portion,
Since they are sequentially formed at substantially the same angle, good staying processing can always be maintained. Further, as described above, since the abrasive grains are always stored in a predetermined layer at the retention interval H, the crushed grains are not removed from the bottom wall 10.
It is possible to prevent the occurrence of abrasion of the bottom wall 10 and the generation of noise or the like due to the contact.

In this crushing structure, the crushing teeth 20

By separating the two, the rotating shaft 13 and the crushing teeth are separated. The crushing teeth 20 can be easily removed outside the machine without disassembling the crushing teeth 20 without disassembly.

On the other hand, as shown in FIGS. 4 and 5, the receiving tooth 21 is formed in a strip shape in a side view, and its tip is directed close to the rotating shaft 13 in the adjacent crushing tooth 20, and The crushing interval formed between the tooth side surface and the crushing tooth 20 is set to about 10 mm on the crushing chamber 4 side and the crushing chamber 6
On the side, the receiving teeth 21 are formed to have a thickness of about 5 mm by making them thicker, and the base thereof is removably mounted and fixed via a mounting screw 25 to a holder portion 23 formed to protrude outside the bottom wall 10. ing. Further, the crushing teeth 20 attached and fixed by the above-described means are protruded from the bottom wall 10 in three rows at coarse intervals as shown in FIG. At the same time, the processing performance can be improved.

That is, the receiving teeth 21 in the first row, which are arranged on the upper side in the rotation direction of the crushing teeth 20, are arranged at a predetermined processing interval from the step portion 10b to improve the initial crushing. The receiving teeth 21 in the second row and the third row are installed at the front and rear portions of the discharge port 12, respectively.
Acceleration of crushing and transfer of crushed particles to the discharge port 12 can be appropriately controlled.

The receiving teeth 21 erected in each row are, from one side of the crushing teeth 20 attached to the rotating shaft 13, the receiving teeth 21 in the first row and the receiving teeth 21 in the second and third rows.

Adjustment of the crushing interval is performed by the receiving teeth 21.
Can be easily and freely obtained by replacing and attaching to a different thickness, or removing a part of the receiving teeth 21 at appropriate intervals. .

Next, the configuration of the sorting room 5 will be described with reference to FIG. In the illustrated example, the sorting chamber 5 has a primary chamber (a workpiece W to be primarily crushed) discharged from the crushing chamber 4 into a hollow chamber communicating with the discharge port 12 of the crushing chamber 4 and the supply port of the crushing chamber 6. Sorting screen 50 for sifting crushed particles, abrasive particles and debris generated by the above-mentioned method, and a dust suction port 5 for sucking light and fine dust-absorbing material (dust) through the dust-absorbing cylinder 9b above the sorting rack 50.

And a rear end thereof is swingably connected to a crankshaft 57 via a support shaft 56, and a shaft end of the crankshaft 57 is connected to a drive motor via a belt 71. 7 to rotate. As a result, while the sorting shelf 50 swings on the support shaft 56 as a fulcrum to instigate the crushed particles, the dust composed of fine particles and dust such as paper dust is sucked and removed by the dust suction device 9a through the dust suction port 51. Further, the filtered crushed particles are directly sent to the sorting device 9 side via the discharge path 53 without passing through the crushing chamber 6 so that the particle size is appropriately selected and the processing load on the crushing chamber 6 is reduced. There are features such as being able to.

The crushing operation of the workpiece W by the crushing apparatus 1 configured as described above is performed by feeding a workpiece W such as a glass bottle into a supply port 3 installed at an upper part of the machine body frame 2 by a belt conveyor or the like. When supplied and supplied by a manual supply means or an artificial supply means, the supplied workpiece W is supplied to the crushing teeth 20 and the bottom wall 1 which are rotated in the crushing chamber 4 in the horizontal direction in the arrow direction.
The discharge port 1 which is primarily crushed between the receiving teeth 21 erected from 0 and is biased toward the front side below the supply port 3 to open.
It is fed from 2 to the lower sorting room 5.

The workpiece W that has reached the sorting chamber 5 is received by the sorting shelf 50, filtered and filtered while being blown, and sent to the next crushing chamber 6 via the supply path 52. .
At this time, large crushed particles and the like, which are thrown vigorously from the crushing chamber 4, are also directed downward by the guide member 59, and the dust and the like are subjected to air suction sorting by the dust suction port 51, and the dust suction device 9 outside the machine is provided. At the same time, the crushed particles having a particle diameter equal to or smaller than an appropriate particle size, which are not absorbed, are passed through the filtration holes of the sorting shelf 50 to be discharged.
, And the workpiece W requiring secondary crushing is promptly fed from the front supply path 52 to the next crushing chamber 6. Accordingly, the sorting chamber 5 accurately removes fine crushed particles, debris, dust, and the like that do not require secondary crushing between the crushing chamber 4 and the crushing chamber 6 in advance.
There is an advantage that the secondary crushing can be efficiently and accurately performed without using unnecessary power.

Next, the workpiece W that has reached the crushing chamber 6 is
The secondary crushing process is performed by the crushing action of the crushing teeth 20 and the receiving teeth 21 similar to those in the crushing chamber 4. Here, the crushed particles that have already been crushed by the primary crushing are re-crushed by the crushing teeth 20 and the receiving teeth 21 similar to those in the crushing chamber 4, so that the crushed particles having a size equal to or less than the size of the crushing gap between them are substantially uniform. The particles are crushed into granules and formed into spherical bead shapes with sharp corners ground, and are discharged from the discharge port 12 together with the powdery crushed particles generated at this time, and are connected via the connecting cylinder 98 to the lower sorting device. 9, the particles are directly transferred by a simple transfer means, and can be efficiently and satisfactorily subjected to the particle size sorting by the sorting rack 50, and are accurately stored in the container for each size of the sorted crushed particles. Then, the crushed particles collected for each particle size are suitably reused for various uses.

In such a crushing operation of the workpiece W, the crushing apparatus 1 of the present invention includes a crushing chamber 4 having a supply port 3 for the workpiece W for performing primary crushing and a primary crushing chamber 4.

The crushing chamber 4, the sorting chamber 5, and the crushing chamber 6 are connected to a dust-absorbing cylinder 9b of a dust-absorbing device 9a.
Since dust and the like generated when the workpiece W is processed in the steps a and 6a are accurately removed in each chamber, the processing load in the next process can be reduced. The dust-absorbing device 9a can satisfactorily remove dust and the like blown up in each chamber simply by sucking the dust and the like. Therefore, the dust-absorbing device 9a is small and inexpensive without increasing the size and size of the dust-absorbing device 9a. It creates advantages such as being able to be employed. In addition, the crushing chambers 4 and the crushing chambers 6 are arranged in the longitudinal direction and are displaced forward and backward through the sorting chamber 5 which is bent in a U-shape between the sorting shelf 50 and the supply path 52 in a side view. There is a structural feature that the drive motor 7 is compactly installed by utilizing the space formed behind it, and the above-mentioned three members can be efficiently driven from one or a plurality of drive motors 7.

The crushing chambers 4 and 6 contain a plurality of crushing teeth 2.

The object W is processed by protruding from the bottom wall 10 and providing a retention interval H between the crushing teeth 20 and the bottom wall 10 for retaining crushed particles and abrasive particles. As a result, a large number of adjacent crushing teeth 20 and receiving teeth 21 do not come into contact with the supplied workpiece W at the same time, thereby reducing vibration noise and the like while suppressing generation of a sudden and excessive load. Then, crushing can be performed smoothly.

At this time, the discharge port 12 opened in the bottom wall 10
Are provided with stepped portions 10a and projections 10c which are directed inward, so that the crushed particles and the abrasive particles are guided by the both to promote the stagnation in the crushing chambers 4 and 6, and the workpiece W It is possible to suitably perform the surface grinding using the abrasive grains generated during the formation of the appropriate crushed particles and the crushing, and the receiving teeth 21 and 21 protruding in front of and behind the discharge port 12 are provided with the object to be treated before and after the discharge port 12. Since the crushing of W is performed and the amount of crushed particles and abrasive particles discharged from the discharge port 12 is appropriately performed, the crushing process can be performed efficiently while increasing the accuracy of the appropriate crushed particles. .

Further, when the crushed object W is rotated and rotated by the crushing teeth 20 as crushed particles, the crushed object W vigorously penetrates into the abrasive particles within the retention interval H and is agitated to form abrasive particles. Because it can be contacted many times, the sharp corners generated at the time of crushing can be accurately and quickly ground and removed, so that crushed grains having a smooth bead-like surface can be efficiently and easily formed. . Therefore,
The crushed particles collected by crushing glass bottles and the like can be easily handled on a surface without sharp corners and are excellent in appearance, so that their effective use and recycling of glass bottles and the like can be promoted. There are advantages.

Processing can be performed efficiently. In addition, between the crushing teeth attached to the rotating shaft that is rotated in the horizontal axis in the crushing chamber, the receiving teeth are made to protrude from the bottom wall by sequentially changing the phase toward the lower side in the rotation direction, and In the meantime, by providing a retention interval for retaining the crushed particles and abrasive particles and treating the object, it is possible to suppress the occurrence of a sudden and excessive load at the time of crushing the supplied object, Noise and the like can be reduced.

Further, the crushed particles can be brought into good contact with the abrasive particles retained within the retention interval, and sharp corners can be accurately and quickly worn away, so that the crushed particles on the smooth bead-like surface can be efficiently removed. It can be easily obtained easily and has advantages such as promoting its effective use. In addition, steps and protrusions provided before and after the outlet on the bottom wall promote stagnation of crushed particles and abrasive particles, and properly retain and discharge the teeth by protruding teeth before and after the outlet. Therefore, it is possible to accurately and satisfactorily perform the crushing of the object to be processed.

Furthermore, the upper and lower crushing chambers are connected and installed above and below the sorting chamber with their discharge ports facing each other, so that the crushing apparatus can be made compact and inexpensive, and the dust suction device or Installation of a sorting device or the like can be easily performed.

Further, a plurality of receiving teeth arranged in the crushing chamber are removably mounted and fixed to the receiving holder, and the receiving holder is removably mounted and fixed from the outside of the crushing chamber.
The structure for mounting the receiving teeth can be simplified, and replacement of the receiving teeth or maintenance work of the crushing chamber can be performed efficiently and easily.

The crushed teeth are accurately supported on the rotating shaft by engaging the crushed teeth with engagement grooves formed at both sides of the support cylinder with a phase angle and mounting the crushed teeth on the rotating shaft. In addition, replacement of crushed teeth can be easily performed.
