Next, the operation of the above embodiment will be described.

First, turn on the power. Power indicator lamp PL _-1 lights up to indicate that the power is on. Turn on the switch PB _-0 , and as shown in Fig. 3, the shutter 25 will move to the paddy supply port 2.
3 is closed, press the rice hulling operation push button switch PB _-3 . At this time, the rising portion 25a of the shutter 25 is not in contact with the limit switch LS _-2 , so the limit switch LS _-2 is
The series circuit 67 side is connected as shown by the chain line in the figure. Shutter close indicator lamp PL _-3 in series circuit 67 lights up, and relay _X4 operates. Therefore, the a contact X _4-a in the series circuit 68 is electrically connected. On the other hand, the rice hulling operation push button switch PB _-4a
is not pressed, so the relay _X3 in the series circuit 69 does not operate, and the b contact X3 _-b in the series circuit 68
is conductive. For this reason, the rice huller drive device 1,
The swinging drive device 51 and the lifting drive device 53 are all driven, and the a contact X _1-a connected in parallel to the hulling operation push button switch PB _-3 is made conductive by the drive of the hulling drive device 1. Self-maintained. At this time, the rice hulling operation display lamp PL _-4 lights up. In addition, when the shutter 25 opens the paddy supply port 26, the limit switch LS _-2 connects the series circuit 65 side as shown by the solid line in FIG.
Since the relay X ₄ does not operate and the a contact X _4-a is not conductive, it is not driven by the hulling drive device 1 or the like.

Feed the paddy to the hopper 17 of the hulling device R, and press the shutter circumferential push button switch PB _-1 . At this time, since both the shutter closing push button switch PB _-2a and the hulling stop push button switch PB _-4a are not pressed, the interlocking switch during series rotation 59 is not pressed.
PB _-2b and PB _-4b are both electrically connected. Therefore,
Relay X ₀ operates, making A contacts X _0-1a and X _0-2a conductive. Pushbutton switch PB ^- ₁ is self-holding. In addition, since there is no fallen rice in the supply tank 37 of the elevator 15, the supply tank 37 is in the upper position.
The protruding piece 37a is not in contact with the limit switch LS _-3 , and the limit switch LS _-3 is connected to the series circuit 63 as shown by the solid line in FIG. Furthermore, since the shutter 25 is closed, _{the limit switch LS -1 connects} the series circuit 63 as shown by the solid line in FIG. Relay X ₂ does not operate, and B contact X _2-b in series circuit 63
conducts. Therefore, relay X ₁ operates, and the a contact X _1-a in the series circuit 55 becomes conductive.
The shutter motor 29 is rotated forward. Shutter 2
5 is opened, and the rising portion 25a moves away from the limit switch LS _-1 and comes into contact with the limit switch LS _-2 . The limit switch LS _-1 is in the state shown by the chain line in FIG. 4, the relay _X1 is reset, the a contact X1 _-a is opened, and the shutter motor 29 is stopped. The shutter open indicator lamp PL _-2 lights up, and at the same time the limit switch LS _-2 becomes as shown by the solid line in FIG.

In this way, when the hulling drive device 1 and the like are driven and the shutter 25 is opened, the rice is removed from the derolling unit 21.
It slips between the two and falls downward. The fallen rice is wind-selected on wind selection road 31. Therefore, the rice husks are blown away, the rice grains are discharged to the outside from the second receiving trough 35, and the fallen rice mixed with paddy and brown rice is conveyed to the elevator 15 via the first receiving trough 33. The fallen rice transported to the elevator 15 is received into the upper supply tank 37, and is supplied to the receiving tank 41 of the swing sorting device 13 at an appropriate time. The fallen rice supplied to the receiving tank 41 is supplied onto each sorting plate 43 and is sorted by the rotating and rocking motion of the sorting plate 43. Then, the paddy is returned to the huller 3 from the paddy discharge port 43a via the paddy receiving trough 45a, and the mixed rice is returned from the mixed rice discharging port 43ab to the mixed rice receiving trough 45b, the conveyance section 47, and the first product receiving trough. 33, the elevator 15, the supply tank 37, and the receiving tank 41 to be supplied again to the sorting plate 43, and the brown rice is supplied to the grain sorter 49 where the grains are sorted.

During such work, in order to inspect each part of the device or to avoid some kind of danger, the rice huller drive device 1
If you want to stop the rice hulling, etc., immediately press the hulling stop pushbutton switch PB _-4a . Relay X ₃ in series circuit 69 is operated, and a contact X _3-2a is made conductive, while b contact X _3-b in series circuit 68 is opened. At this time, since the shutter 25 is open, the limit switch LS _-2 is in the state of connecting the series circuit 65 as shown by the solid line, so the relay X ₄ does not operate and the b contact X on the series circuit 68 side _Four-
b is conductive. Therefore, the hulling drive device 1 and the like are being driven. Due to the operation of relay _X3 , a contact _X3-1a on the side of series circuit 65 is made conductive, and relay _X2 is operated. When the relay X ₂ is operated, the a contact X _{2 -1a} in the series circuit 57 is made conductive, the H motor 29 is reversed, and the shutter 25 closes the paddy supply port 23 . When the shutter 25 is closed, the limit switch LS _-2 becomes as shown by the chain line in FIG. 4, and the relay _X4 is operated. When the relay X ₄ is operated, the b contact X _4-b is opened and the hulling drive device 1 etc. are stopped. Therefore, if the hulling stop push button switch PB _-4a is pressed while the shutter 25 is open, the hulling drive device 1 etc. will be stopped after the shutter 25 is closed. When the hulling drive device 1 and the like are stopped, the b contact X _1-b between the nodes P ₂₁ and P ₄₃ is electrically connected, and the hulling stop indicator lamp PL _-5 lights up.
Note that when the shutter 25 is open and the hulling drive device 1 etc. is being driven, if the shutter closing push button switch PB _-2a is pressed to close the shutter 25, the hulling stop push button switch PB _-4a is pressed. As a result of this operation, the hulling drive device 1 immediately stops.

The shutter 25 is open and the rice huller drive device 1
When the elevator 15 is being driven, fallen rice accumulates in the supply tank 37 of the elevator 15, and when the supply tank descends, the protrusion 37a comes into contact with the limit switch LS _-3 . Limit switch LS _-3 is switched as shown by the chain line in FIG. 4, and relay _X2 is operated. By the operation of relay X ₂ , in the same way as above,
The shutter motor 29 is reversed, and the shutter 25
closes the paddy supply port 23. Therefore, paddy is not supplied, and after a predetermined period of time, the fallen rice is no longer supplied to the supply tank 37, and the fallen rice does not overflow from the supply tank 37.

Note that this invention is not limited to the above embodiments. Therefore, in the above embodiment, the shutter 25 is opened and closed by the shutter motor 29, but the shutter 25 may be opened and closed manually. In this case, a detection device is provided to detect that the shutter 25 is closed, and only when this detection device detects, the b contact X _{4 -b} in the drive circuit of the hulling drive device 1 etc. is opened. In addition, a detection device is provided to detect the presence or absence of a roll load due to the presence or absence of paddy while the unrolling ₂₁ is rotating, and this detection device is interposed between _{the relay} may cause relay _X4 to conduct. In this case, even if the shutter 25 is open, the hulling drive device 1 and the like can be stopped if the paddy is not supplied between the derolling sections 21.

As described above, the present invention is provided with a detection device 5 that detects that no paddy is supplied to the huller 3 which is driven by the huller drive device 1 and removes the supplied paddy, and only when the detection device 5 detects that the paddy is removed. Since the stop regulating device 7 that enables the sliding drive device 1 to be stopped is provided,
When paddy is being supplied to the hulling machine, the hulling drive device cannot be stopped, and if the hulling machine is not supplied with paddy, the detection device detects this and activates the stop regulation device, and the hulling machine is stopped. Allows the drive to be stopped. Therefore, when the huller is stopped, the entire weight of paddy newly supplied to the huller is not added to the huller while it is being unrolled, and the huller is restarted under a light load. This can be done very easily. Moreover, damage to the derolling of the huller is also prevented.
