(Configuration example 1)
First, a first configuration example will be described.
The rice milling machine 1a according to the first configuration example of the present invention is shown in FIG. 1 and FIG. 2 which are a longitudinal sectional side view and an internal perspective plan view of the main part at the time of maintenance. Brown rice hopper 2 discharged from 2a, milling roll 3 for rotating and milling brown rice received from this brown rice hopper 2, and milled grains receiving the action of this milling roll 3 are fed from the brown rice mouth 2a side to the white rice outlet 4a side at the front end. A cylindrical guide removal unit 4 that removes the guide while removing it, and a rod guide 5 that guides the rod received from the guide removal unit 4 downward, are housed in a box-shaped exterior frame F. The maintenance is possible from the front door D.

  The brown rice hopper 2 is provided with a shutter 6 for opening and closing the brown rice entrance 2a. The shutter 6 is formed with a through-hole 6a having a shape W corresponding to the brown rice entrance 2a, and the through-hole 6a is supported on the bracket 2b so as to enable a sliding operation S in the front-rear direction to a closed position where the brown rice entrance 2a is removed. A coil spring 7 is provided as a biasing member that biases and holds the shutter 6 in the closed position.

  The guide dehulling unit 4 is configured so as to be able to be taken out along the axis of the kneading roll 3 integrally with the kneading adjustment unit 4b provided at the white rice outlet 4a. Further, the guide dehulling unit 4 has a range that interferes with the shutter 6. A counter part 4c is provided so as to resist the urging force of the urging member 7 of the shutter 6 by directly or indirectly interfering with the shutter 6 when the guide removal part 4 is attached. Then, the shutter 6 is disposed at a related position for holding the shutter 6 in the open position.

  The rice milling machine 1a configured as described above can open and close the brown rice port 2a at the lower end of the brown rice hopper 2 with a shutter 6, and this shutter 6 is urged and held in a closed position by a urging member 7, while being attached. The opposing portion 4c of the guide removal portion 4 acts to hold the shutter 6 in the open position against the urging force of the urging member 7.

  Therefore, during the operation of the rice mill 1a, by holding the shutter 6 in the open position, the input brown rice stored in the brown rice hopper 2 is dropped and supplied from the brown rice port 2a to the milling roll 3, thereby allowing the rice to be polished. On the other hand, when the guide removal part 4 is taken out in the direction of the white rice outlet 4a at the front end by the take-out operation A, the opposing force by the opposing part 4c of the guide removal part 4 is lost and the shutter 6 is automatically activated. Energized and held in the closed position, the brown rice entrance 2a is closed.

As described above, when the rice milling machine 1a is maintained, the shutter 6 is automatically closed by removing the guide removal unit 4 without requiring a prior shutter operation, so that the brown rice remains in the brown rice hopper 2. For the case where the guide rice removal part is taken out without incurring the situation of brown rice dissipation from the brown rice hopper that will be caused by forgetting the previous shutter operation or annoying operational procedure mistakes, etc. Maintenance work can be performed.
In addition, by taking out the guide removal unit 4, the remaining rice in the milling unit is accommodated in a basket receiving box or the like.

(Configuration example 2)
Next, a second configuration example will be described. In the following description, the same members as those described above are denoted by the same reference numerals and description thereof is omitted.
A rice mill 1b according to a second configuration example of the present invention includes a shutter 6 that is slidably supported on a bracket 2b as shown in FIGS. 3 and 4 in which a longitudinal sectional side view of a main part during milling and an internal perspective plan view during maintenance are shown. The receiving part 6b is extended from the front end of the door, and the opposing part 14c is projected inward from the front door D in a range where it interferes with the receiving part 6b. The opposing part 14c is in a state where the front door D is closed. By directly or indirectly interfering with the shutter 6, the shutter 6 is disposed at a related position that holds the shutter 6 in the open position against the urging force of the urging member 7 of the shutter 6.

  The rice mill 1b having the above-described configuration can open and close the brown rice port 2a at the lower end of the brown rice hopper 2 with the shutter 6, and the shutter 6 is urged and held at the closed position by the urging member 7, while being closed. The counter part 14c of the front door D acts so as to hold the shutter 6 in the open position against the biasing force of the biasing member 7.

  Therefore, when the front door D is closed, the opposing portion 14c acts on the receiving portion 6b and the shutter 6 is held in the open position, so that the input brown rice stored in the brown rice hopper 2 is refined from the brown rice entrance 2a. It is dropped and supplied to the roll 3 and rice milling becomes possible. On the other hand, when the opposing portion 14c is detached from the receiving portion 6b by the opening operation B of the front door D, the opposing force by the opposing portion 14c is lost, and the shutter 6 is automatically biased and held in the closed position. Since the brown rice entrance 2a is closed, the guide removal part 4 can be taken out from the opening of the front door D.

  As described above, when the rice milling machine 1b is maintained, the shutter 6 is automatically closed by opening the front door D without requiring a prior shutter operation, and thus the brown rice remains in the brown rice hopper 2. The guide removal part 4 is taken out without incurring the situation of brown rice dissipating from the brown rice hopper, which is caused by forgetting the previous shutter operation or mistakes in troublesome operation procedures, etc. Work can be carried out.

(Configuration example 3)
Next, a third configuration example will be described.
A rice mill 1c according to a third configuration example of the present invention includes a shutter 26 that can open and close the brown rice entrance 2a, as shown in FIGS. And an operating member 27 for opening and closing the shutter 26 is provided. Further, the lock member L that engages with the guide removing portion 24 and restricts its removal when the shutter 26 is in the open position is configured integrally with the shutter 26 or capable of interlocking with the shutter 26.

  In the illustrated example, the shutter 26 is used as a lock member L so that the removal of the guide removal unit 24 can be regulated. In other words, a shutter 26 is pivotally supported at the brown rice port 2a of the brown rice hopper 2 so that an opening / closing operation θ is possible. At the position where the shutter 26 is opened downward, at least a part of the shutter 26 is guided below. The shutter 26 is arranged in a range that engages with the brown rice receiving opening 24 a that opens in the portion 24. Further, a knob 27a is provided at one end of the operation member 27, and the operation member 27 is slidably supported on the bracket 2c so that the shutter 26 can be switched from the open position to the closed position by the slide operation S by the forward / backward operation C of the knob 27a.

    The rice milling machine 1c configured as described above can open and close the brown rice port 2a at the lower end of the brown rice hopper 2 by the shutter 26 via the operation member 27 slidably supported on the bracket 2c. Since the lock member L is released only when the shutter 26 is in the closed position and the guide dehulling portion 24 can be removed, the brown rice hopper 2 can be removed in advance. The guide removal unit 4 is taken out and maintenance work is performed from time to time without incurring brown rice dissipating from the brown rice hopper, which may be caused by forgetting to operate the shutter or annoying operational procedures. can do.
