Next, the thin rod pushing and folding apparatus 2 will be described as follows. That is, the rotation drive shaft 15 is provided laterally at the uppermost part of the frame 5 via the bearings 14, 14. A large number of pressing plates 16 each having a projection 16a extending in the direction of the radius of rotation of
They are fixed in parallel at a pitch of about 4 cm.

The projections 16a of each of the pressing plates 16 are provided with three projections in an equiangular arrangement around the rotation center line, and a large number of groups of the pressing plates 16 are formed as shown in FIG. 1
The configuration is such that the phase of the fixed position of each pressing plate 16 is sequentially changed from one end of the rotary drive shaft 15 to the other end so that the position 6a gradually changes around the rotation center thereof.

The lower end of the rear bottom wall 6c of the supply funnel 1 is brought close to the upper half of the group of pressing plates 16 and is disposed so as to reach the right side of the rotary drive shaft 15. At the lower end of the wall 6c, a number of cuts a corresponding to the respective pressing plates 16 are arranged in parallel so that rotation of the group of pressing plates 16 is not hindered.

On the other hand, a support shaft 17 as a fixed member along the rotary drive shaft 15 is fixed to the frame 5.
As shown in FIGS. 2 and 4, a receiving plate 18 is fixed to the support shaft 17 at a substantially central position between the pressing plates 16 of the pressing plate 16 group and in a parallel manner.

Each receiving plate 18 has a substantially horizontal receiving portion 18a, and the tip of the receiving portion 18a is extended to the root of the projection 16a of the pressing plate 16 as shown in FIG. It has been done.

The lower end of the front bottom wall 6b of the supply funnel 1 is brought close to the receiving portion 18a, and its leading edge is located on the right end of the receiving portion 18a.

Next, the fine rod crushing device 3 will be described as follows. That is, as shown in FIG. 1, a pair of right and left parallel The rotating shafts 19 and 20 are provided sideways, and the spur gears 21a and 21b are fixed to the rotating shafts 19 and 20, respectively, and the gears 21a and 21b mesh with each other, and rotate in the arrow directions f1 and f2 opposite to each other. There is a configuration to make it.

At this time, at least one of the pair of rotary shafts 19, 20 is driven. Each of the gears 21a, 21b has eight modules in this embodiment in view of the size of the workpiece w. The number is 12.

Next, the soft stripping device 4 will be described as follows. That is, two spur gears 21a,
Immediately below 21b, there is provided a pair of gears 22a and 22b to which the processed material w that has been bitten out of these gears 21a and 21b is supplied, and each of the gears 22a and 22b has a sharpened peripheral surface with a triangular cross section. The gears 22a are driven by a relatively large peripheral speed in the direction f1 of the arrow, and the other gear 22b is driven by the arrow in the direction of the arrow f1. It is configured to rotate at a relatively small peripheral speed in the direction f2. At this time, it is preferable that the teeth of the two gears 22a and 22b be as close as possible under non-meshing conditions.

Next, the drive system of the thin rod pushing / folding device 2 and the thin rod crushing device 3 will be described. As shown in FIGS. A motor device 24 with a mechanism is provided.
4 is transmitted to one rotation shaft 19 via a transmission mechanism including two gears 25a and 25b, and the rotation of the other rotation shaft 20 is rotationally driven via a transmission mechanism including two gears 26a and 26b. It is configured to transmit to the shaft 15. Further, the rotation of the motor device 24 is transmitted to the two gears 22a and 22b by an appropriate transmission mechanism (not shown).

The configuration of the fine rod crushing machine of the present invention has been described above. Next, an example of use and operation thereof will be described. Prior to use, the user suspends the plastic bag b for dust collection under the soft stripping device 4 by suspending it as shown in FIG. 3, and then sets the start switch of the control panel. Enter operation. As a result, an initial operation state of the entire processing machine is established, and the motor device 24 enters a rotatable state and waits.

After this state, the user depresses the foot pedal 9 to open the hinged lid 8b, and the
A used disposable chopstick w is fed into the supply funnel 1 through a.

After the closing, the foot pedal 9 is released. As a result, the hinged lid 8b is automatically closed by the action of gravity or by the force of a spring (not shown). In connection with this closing, the magnet holders 12, 12 are closed.
Is turned on, and when the chopstick w is present in the supply funnel 1, the motor device 24 is rotated.

The rotation of the motor device 23 is controlled by one of the rotation shafts 19.
Is rotated at a speed of about 10 to 20 rpm, and this rotation rotates the other rotating shaft 20 at the same speed via the spur gears 21a and 21b. The rotation of the rotation shaft 20 is further transmitted to the rotation drive shaft 15, and also rotates the group of pressing plates 16 at a speed of about 10 to 20 rpm.

The split chopsticks w in the supply funnel 1 move on the receiving portion 18a of the receiving plate 18 by the action of gravity, and the pressing plate 16 group moves the chopsticks w toward the receiving portion 18a relatively slowly. This causes the chopsticks w to be pressed at a plurality of locations in the longitudinal direction of the chopsticks w so that each receiving portion 1
At 8a, the length is cut to about 1 to 4 cm.

At this time, the relatively slow rotation of the group of pressing plates 16 enables the chopsticks w to be cut with less noise, and the distance between the pressing plates 16 and the receiving plate 18 is about 1 to 4 cm. This makes it possible to stably cut the chopstick w and to cut the chopstick w into a length suitable for the next processing. In addition, the phase of the projection 16a of each pressing plate 16 of the pressing plate 16 group Is gradually changed without cutting the chopsticks w at the same time to reduce the maximum load acting on the rotary drive shaft 15.

The split chopstick w cut by the pressing plate 16 and the receiving plate 18 falls below the receiving portion 18a and reaches the biting side of the two spur gears 21a and 21b.

The two spur gears 21a and 21b operate to bite and flatten the dropped chopstick pieces w by biting and sometimes pinching the dropped chopstick pieces w, and to operate downward. At this time, when the spur gears 21a and 21b bite a large number of split chopsticks w at a time, the spur gears 21a and 21b move so as to expand the gap against the force of a spring (not shown), and an excessively large load is applied. On the spur gears 21a, 21b. At this time, the fact that the spur gears 21a and 21b have 8 modules and 12 teeth contributes to smooth and moderately flattening the processing object w having a cross-sectional size similar to that of chopsticks.

The flattened split chopsticks w are
a, falls in the middle on 22b, and two gears 2
2a, 22b pulls the chopsticks w between the teeth by rotation, and tears them in a shearing manner due to the difference in their peripheral speeds.
In addition, it is softened and fragmented by hitting with teeth.
Such processing using gears is performed quietly as compared with processing using a rotary blade. The processed material at this time falls into the plastic bag b.

When the number of chopsticks w in the supply funnel 1 becomes small, replenishment is successively performed. When the hinged lid 8b is released by the above-described operation for replenishment, the opened state is changed to the magnet holder 12, The twelve limit switches detect and immediately stop the motor device 23. When the refill of the chopsticks w is completed and the hinged lid 8b is closed, the limit switch is switched and the motor device 23 is reactivated.
To rotate. Therefore, when the chopsticks w are supplied to the supply funnel 1, the user can escape from the danger caused by the rotation of the pressing plate 16 and the receiving plate 18.

When the chopsticks w to be replenished run out and the chopsticks w in the supply funnel 1 are reduced, the photoelectric sensor 13 detects this and activates an appropriate timer mechanism to leave the chopsticks w in the supply funnel 1. After a certain period of time when the processing of the chopsticks w is completed, the motor device 24 is automatically stopped.

The treated material w thus housed in the plastic bag b is provided to the market as a material for organic fertilizer.
It may be sprayed on the farm as it is, or may be ripened in advance and sprayed.

Next, a modification of the above embodiment will be described. (1) The soft slicing device 4 may be replaced with an appropriate hammer crushing device. In this case, it is possible that only the processed product w in the form of powder falls into the plastic bag b. is there. (2) Depending on the use, the thin rod pushing / folding device 4 may be omitted.

[0037]

According to the present invention having the above structure, the chopsticks and the like can be cut into small pieces, swelled and softened appropriately by cutting, crushing and tapping, so that the chopsticks are suitable for organic fertilizer. It can be changed.

According to the second aspect of the present invention, the processing is somewhat crude, but is sufficiently practical.
