A switching shaft 25 for reversing the switching plate 24 so as to close the rice-side downflow gutter 22 (or the outside-side downflow gutter 21) from the 1 (or rice-downflow gutter 22), and is connected to the switching shaft 25 and protrudes out of the machine. And an operation lever (not shown). Accordingly, the switching shaft 25 is rotated by the switching operation of the operation lever, and the switching plate 24 closes the outside downflow gutter 21 to open the rice mill downflow gutter 22, and the switching shaft is operated by switching the operation lever in the opposite direction. 25 is rotated in the reverse direction, and the switching plate 24 closes the rice mill-side downflow gutter 22 and opens the outside-machine downflow gutter 21. Reference numerals 40, 40 are stoppers for maintaining the open / closed state by the switching plate 24.

[0010] As described above, it is possible to take out the crushed brown rice sorted by the sorting board 16 outside the machine by using the outside downflow gutter 21 communicating outside the machine. In addition, the branch downstream part 20 is provided with an overflow gutter 27 that opens at a position immediately below the brown rice discharge part 26 of the sorting board that protrudes into the branch downstream part 20, and the lower end of the overflow gutter 27 is brown rice. When the inside of the branch flow lower part 20 is full of brown rice from the brown rice discharge part 26, the subsequent brown rice can be recirculated to the fill port 6 by the overflow gutter 27 when the lower part of the branch flow 20 is filled with brown rice from the brown rice discharge part 26. ing.

On the other hand, the outlet of the down flow gutter 22 on the rice mill side is arranged above the hopper 28 for the rice mill, so that the browned rice that has been destoned can be supplied into the milling chamber 30. At the lower end of the hopper 28, a brown rice detection sensor 29 is provided.
A supply shutter 31 is provided for opening and closing the passage to zero.

The milling machine 4 has a milling roll 32 in a milling room 30.
The bran at this time is sent from a bran removing screen 33 as a separated bran to a bran processing section (not shown) by a suction fan 34. The milling roll 32 is a main motor 35
The suction fan 34 is driven by a fan motor 36. On the outlet side of the refining chamber 30, a resistance plate 37 is provided, and the pressure can be adjusted by the resistance plate 37 by adjusting the spring pressure pressing the resistance plate 37. By turning the whiteness dial 38 for adjusting the whiteness, the whiteness can be set stepwise. Reference numeral 39 denotes a gutter for removing white rice provided on the exit side of the refining chamber 30.

Next, an operation and an operation procedure of the above-described stone milling machine 1 will be described. First, the user selects the switching direction of the switching device 23 according to whether the user needs unpolished brown rice or polished white rice. Next, after putting brown rice into the insertion port 6, the operation switch of the operation panel is turned on, and the screw 10 and the lifting device 8 are turned on.
And the destoner motor 19 starts moving, and the destoner 5 starts operating. At this time, the main motor 35 and the fan motor 36 of the rice milling machine 4 have not yet moved.

The brown rice supplied from the insertion port 6 is continuously fed by a fixed amount toward the lower entrance of the lifting device 8 as the screw 10 rotates. The brown rice that has flowed into the elevating device 8 is discharged into the bucket 11 while being grained in the bucket 11.
5 is supplied to the hopper 17 of the destoner. Brown rice supplied from the hopper 17 onto the sorting board 16 is subjected to a stone removing operation, and is separated into brown rice and stone chips.

In this way, the brown rice from which the stones have been removed and sorted flows down the branch flow 20 and reaches the switching device 23. If the switching direction of the switching plate 24 is operated so that the rice mill downflow gutter 22 is opened, The brown rice flows into the hopper 28 of the rice mill. The brown rice detection sensor 2 in the hopper 28
When the brown rice 9 is covered with brown rice, the main motor 35 and the fan motor 36 of the rice milling machine rotate with a delay of T time in response to the brown rice detection signal from the sensor 29, and the operation of the rice milling machine 4 is started. The T time is provided to prevent shortage of brown rice in the rice polishing machine hopper 28 immediately after the start of rice polishing, and the rice polishing machine 4 is operated after a certain amount or more is accumulated in the hopper 28. It is set to.

When the rice mill 4 starts operation, the supply shutter 31 is opened, and the brown rice is subjected to a whitening action by the milling roll 32, turned into white rice, and discharged out of the gutter 39 for taking out white rice. By the way, at this time, when the amount of milled rice in the milling machine 4 is smaller than the amount of brown rice supplied from the crusher 5, for example, when the milling machine 4 is operated in a half-open state without fully opening the supply shutter 31, Brown rice in the rice polishing machine hopper 28 becomes full, and further, the inside of the branch flow lower portion 20 provided with the switching device 23 becomes full. Then, when the subsequent brown rice from the destoner 5 is continuously supplied without interruption, it reaches the opening of the overflow gutter 27, so that the excessive brown rice supplied in excess flows through the overflow gutter 27 and returns to the inlet 6 again. I do. By adopting the recirculation system in this way, the destoner 5, the lifting device 8, and the screw 10 at the insertion port are prevented from being jammed with rice, and smooth operation is ensured.

On the other hand, if the switching direction of the switching plate 24 is operated so as to open the downflow gutter 21 on the outside of the machine, the crushed brown rice supplied from the destoner 5 to the branch downflow 20 is switched by the switching device 23. It is discharged to the outside of the machine through the outer flow down gutter 21 and is housed in a bag prepared in advance, for example. In this case, since the brown rice is not supplied to the rice hopper 28, the brown rice detection sensor 29 does not operate, so that the main motor 35 and the fan motor 36 of the rice mill do not move. 8 and only the operation of the destoner 5. Further, similarly to the case of the above-described rice polishing, when the brown rice is filled up in the downflow gutter 21 outside the machine and the subsequent brown rice exceeds the opening of the overflow gutter 27, the excess excess rice flows from the overflow gutter 27 to the insertion port 6. Recirculates.

FIG. 4 shows a second embodiment of the present invention. The difference from the first embodiment is that
Is that the brown rice is directly put into the hopper 17 of the destoner, that the brown rice that has been destoned by the destoner 5 is to be directly grained by the lifting device 8, and that the lifting device The outlet 15 has a branching downstream part 20 whose lower side is bifurcated. A switching device 23 is provided at a branch point of the branch downstream portion 20, and one of the outside downstream gutters 21, which can be opened and closed by the switching device 23, communicates with the outside of the machine, and the other rice-side downstream gutter 22 is connected to the outside. It is arranged above the hopper 28 of the rice mill 4. An overflow gutter 27 communicating from the branch flow lower portion 20 is provided at an upper portion of the switching device 23 in the branch flow lower portion 20, and a lower end of the overflow gutter 27 is disposed above the crusher hopper 17 so that an overflow gutter 27 is provided. The brown rice can be put into the hopper 17 again.

[0019]

According to the stone milling machine of the present invention, a branch downstream portion provided with a switching device capable of changing the flowing direction of the unmilled brown rice is provided at an intermediate portion between the stone milling machine and the rice milling machine. It can be freely switched to the outside of the machine or the rice hopper side by switching operation, so it can be easily used for one machine to use for unmilled brown rice and white rice for polished rice according to the use purpose, and good operability. In addition, the equipment cost is low and the installation space is more efficient. Further, by providing a gutter for overflow in the lower part of the branch flow (claim 2), the operation of the rice milling machine can be smoothly performed without any trouble.
