[0017]
Thus, when the shutter member 18 is opened and retracted as the lid member 1d is closed, the intermediate plate 21b is pushed downward by the inclined action of the inclined surface portion 18c and the inclined surface portion 21c. Is pushed down against the built-in spring, and the switch button 21g is closed, so that the rotation of the motor 15 can be started, and the shutter member 18 is moved in accordance with the opening of the lid member 1d. When the closing opening is advanced, the pressing plate 21e is pushed up by the switch button 21g biased upward by the built-in spring, the intermediate plate 21b is also pushed up by the pressing plate 21e, and the switch button 21g is opened, thereby rotating. The motor 15 stops and becomes non-rotatable.
[0018]
Since this embodiment is configured as described above, grains W such as rice, wheat, soybeans, corn and the like, dried mushrooms, boiled, eggshell, dried shrimp, tea leaves, Chinese herbal medicine raw materials, etc. are provided in the hopper part 1. 5 and the drive unit 3 rotates the rotary crusher 7 in the direction of the solid line arrow in FIG. 5. In other words, it can be considered that the fixed crusher 6 is relatively rotated in the direction of the broken line arrow as shown in FIG. 6. The object to be crushed W is sent to the outside while being crushed by the crushing gap H of the crushing part 2 composed of the fixed crusher 6 and the rotary crusher 7, and the crushed object W is discharged to the discharge part. In this case, a lid member 1d capable of opening and closing the charging port 1c of the hopper portion 1 is disposed, and the introduction path 13 between the hopper portion 1 and the crushing portion 2 is opened and closed. Possible shutter member 18 is disposed, and the opening / closing operation of lid member 1d and the shutter The opening / closing operation of the member 18 is interlocked by the interlocking mechanism 19, and the interlocking mechanism 19 quickly closes the shutter member 18 associated with the opening operation of the lid member 1d, and the shutter member 18 associated with the closing operation of the lid member 1d. Since the control mechanism 20 for delaying the opening operation is provided, the introduction path 13 can be immediately closed by the shutter member 18 following the opening operation of the lid member 1d, and the closing operation of the lid member 1d is almost completed. Thus, the introduction path 13 can be closed by the shutter member 18, the externally exposed state of the crushing portion 2 can be reduced by that much, and the safety of use with respect to the rotating crusher 7 can be enhanced.
[0019]
Further, in this case, since the safety mechanism 21 that allows the drive unit 3 to drive and rotate the rotary crusher 7 is provided in conjunction with the completion of the closing operation of the lid member 1d, the lid member 1d is not closed. Since the rotation of the rotary crusher 7 is not possible and the rotation of the rotary crusher 7 is stopped when the lid member 1d is opened, the safety can be further improved. Since the operation pin 29 attached to the member 1d side and the floating groove 31 formed on the operation link 27 side for moving the shutter member 18 back and forth, the delay amount can be reduced by changing the length M of the floating groove 31. It can be easily changed and the structure can be simplified.
[0020]
Note that the present invention is not limited to the above-described embodiment, and the structure, form, material, and the like of the hopper portion 1, the crushing portion 2, the drive portion 3, and the discharge portion 4 are designed with appropriate changes. is there.
[0021]
【The invention's effect】
As described above, according to the present invention, the lid member capable of opening and closing the charging port of the hopper portion is disposed, and the introduction path between the hopper portion and the crushing portion is opened and closed. Possible shutter members are arranged, and the opening / closing operation of the lid member and the opening / closing operation of the shutter member are interlocked by an interlocking mechanism, and the interlocking mechanism quickly closes the shutter member accompanying the opening operation of the lid member and the lid Since a control mechanism is provided for delaying the opening operation of the shutter member accompanying the closing operation of the member, the introduction path can be closed immediately by the shutter member following the opening operation of the lid member, and the closing of the lid member is also possible. until just before the completion operation can block the introduction passage by the shutter member, it is possible to reduce the external exposure condition of much to潰部, it is possible to increase the safety of use of the relative rotation to 潰盤, Since the control mechanism is composed of an operating pin attached to the lid member side and a floating groove formed on the operating link side for moving the shutter member forward and backward, the delay amount can be easily changed by changing the length of the floating groove. And a safety mechanism that allows the rotation of the rotary crusher to be driven by the drive unit in conjunction with completion of the closing operation of the lid member. Since the rotating crusher cannot be rotated unless the member is closed, the safety can be further improved.
