Is in the swinging-in state, the circulation / discharge switching valve 36 is switched to the circulation side, the hulling operation of the circulation process is started (step S6), and then the first indicator lamp L1 is turned off (step S7).

  Next, it is determined from the detection information of the mixed rice sensor SE1 whether or not a predetermined amount or more of mixed rice has accumulated in the mixed rice tank 24 (step S8). If Yes, the second indicator lamp L2 is turned on (step S9). The shutter lever 32 is operated from the second operation position 32c to the third operation position 32d by the operator (step S10), the shutter valve (31) is in the open state, the swing clutch 39a is in the swing-in state, circulation / discharge The switching valve (36) is switched to the discharge side, and the cereal sorting operation is performed with the selected grains of the swing sorting plate 15 being discharged from the machine (step S11), and then the second indicator lamp L2 is turned off (step S11). S12) In this state, the hull sorting operation is continued.

  Next, the process proceeds to “B” in FIG. 10 and the rice hull sorting operation is continued in the same state (step S14), and then whether or not the amount of mixed rice in the mixed rice tank 24 becomes a predetermined amount or less is determined. Judgment is made based on the detection information of the sensor SE1 (step S15). If Yes, the third indicator lamp L3 is turned on (step S16), and the operator operates the shutter lever 32 from the third operation position 32d to the second operation position 32c. If it does (step S17), the 3rd indicator lamp L3 will be light-extinguished (step S18), and the remaining rice processing process which makes a residual grain the whole grain brown rice will be performed, making the selection grain of the rocking | pulverization sorting board 15 into an in-machine circulation state. (Step S19).

  Next, it is determined whether or not the detected load current value of the load current sensor SE5 has fallen below a predetermined value (step S20). If yes, the fourth indicator lamp L4 is turned on (step S21), and the shutter is operated by the operator. The lever 32 is operated from the second operating position 32c to the first operating position 32b (step S22), the shutter valve 31 is closed, the swinging clutch 39a is swinging off, and the circulation / discharge switching valve (36) is circulating. (Step S22), the fourth indicator lamp L4 is turned off (step S23), then the operation / stop switch SW1 is turned off by the stop command from the controller 55, and the remaining rice processing step is completed (step S24). ).

Next, another control content for automatically executing the remaining rice processing step will be described based on the flowcharts of FIGS.
After step S13 in FIG. 9, the process proceeds to “B” in FIG. 17, and the rice hull sorting operation is continued in the same state (step S31), and then the amount of mixed rice in the mixed rice tank 24 becomes a predetermined amount or less. Is determined by the detection information of the mixed rice sensor SE1 (step S32). If Yes, the third indicator lamp L3 is turned on (step S16), and the shutter lever 32 is moved from the third operation position 32d by the operator. When the second operation position 32c is operated (step S17), the third indicator lamp L3 is turned off, and the remaining rice processing step for converting the residual grain into the whole brown rice while keeping the selected grain of the swing sorting plate 15 in the in-machine circulation state. Is executed (step S35).

  In step S32, the mixed rice sensor SE1 detects that the amount of mixed rice in the mixed rice tank 24 has become a predetermined amount or less, and the load current sensor SE5 detects the load current value of the main motor M1. The third indicator lamp L3 may be lit.

  Next, after a set time (for example, 5 minutes), the circulation / discharge switching valve 36 is switched from the circulation side to the discharge side according to a command from the controller 55 (step S36), and then the detected load current value of the load current sensor SE5 is equal to or less than a predetermined value. (Yes in step S37), the fourth indicator lamp L4 is turned on (step S38), and the shutter lever 32 is moved from the second operation position 32c to the first operation position 32b by the operator. When operated, when the shutter valve 31 is closed, the swing clutch 39a is turned off, and the circulation / discharge switching valve (36) is switched to the circulation side, the fourth indicator lamp L4 is turned off by a command from the controller 55. Subsequently, the operation / stop switch SW1 is turned OFF by the stop command of the controller 55, and the remaining rice processing step is ended (step S39). .
