If it is ON, the swing motor M3 is turned OFF, the circulation / discharge switching valve 31 is switched to the circulation side, and the shutter 6a is closed. The adjustment is made and the main motor M1 is turned off (step S15).

  When there is no new rice supplied to the rice hopper 6 and the rice breaker sensor SE3 detects the absence of rice cake hopper 6, the rice remaining in the residual rice is crushed to be used as brown rice and discharged out of the machine. Perform the process. In this residual rice treatment process, the circulation / discharge switching valve 31 is switched to the circulation side, and then the swing motor is turned on to start swinging of the swing sorting plates 15,. Circulate between the rice huller 1 and the mixed rice sorting unit 3 until it becomes, and then the circulation / discharge switching valve 31 is switched to the discharge side to discharge the remaining rice out of the machine.

(Step S62) If Yes, the circulation / discharge switching motor M4 is switched to the circulation side (Step S63), and the circulation side switching drive is continued until the switching valve (circulation) sensor SE4 is turned on (Step S64). ).

  Further, it is determined whether or not the mixed rice tank full sensor SE12 is ON (step S61). If Yes (full), the circulation / discharge switching motor M4 is switched to the discharge side (step S65), and the switching valve ( (Discharge) The drive to switch to the discharge side is continued until the sensor SE5 is turned on (step S66).

According to the above configuration, when the mixed rice tank 24 is full, the circulation / discharge switching valve 31 is automatically switched from the circulation side to the discharge side, thereby facilitating the operation of the operator.
Moreover, you may comprise as FIG. In this embodiment, when the mixed rice shutter 24a of the mixed rice tank 24 is opened and closed during operation, the circulation / discharge switching valve 31 is automatically changed from the discharge side to the circulation side or from the circulation side to the discharge side. It is intended to facilitate switching and operator operation.

  As shown in FIG. 11, when the mixed rice shutter 24a of the mixed rice tank 24 is opened to closed (step S71), the circulation / discharge switching valve 31 is switched from the discharge side to the circulation side (step S72). When the (circulation) sensor SE4 is turned on (step S73), the switching drive of the circulation / discharge switching valve 31 to the circulation side is stopped (step S74).

Step S77), the switching drive of the circulation / discharge switching valve 31 to the discharge side is stopped (step S78).

  In the conventional apparatus, every time the mixed rice shutter 24a of the mixed rice tank 24 is opened and closed, the circulation / discharge switching valve 31 is switched from the discharge side to the circulation side by manual operation, or is switched from the circulation side to the discharge side. However, according to the above configuration, the circulation / discharge switching valve 31 can be automatically switched when the mixed rice shutter 24a of the mixed rice tank 24 is opened and closed, and the operability can be improved.

Next, another embodiment will be described based on FIGS. 3 and 12.
As shown in FIG. 3, on the discharge side of the swing sorting plate 15, a brown rice layer thickness sensor SE 14 is provided on the swing side, and a cocoon layer thickness sensor SE 15 is provided on the swing side, and these sensors are connected to the input side of the controller 41. Connected to. On the output side of the controller 42, a swing sorting plate tilt adjusting motor M5 for tilt adjustment of the swing sorting plate 15 and a brown rice partition plate adjusting motor M6 for adjusting the partition position of the brown rice partition plate 18 are connected. .

The controller 41 is provided with residual rice processing control means that, when the breakage sensor SE3 of the straw hopper 6 detects the breakage, grinds the straw in the residual rice of the mixed rice sorting unit 3 to make all the brown rice.
As shown in FIG. 12, when the control is started, detection information of the brown rice layer thickness sensor SE14 and the culm layer thickness sensor SE15 is input to the controller 41 (step S81), and the operation mode is determined (step S82). When the cut-off sensor SE3 is OFF (having wrinkles), it is determined as normal operation control. When the cut-off sensor SE3 is ON (no wrinkle) and the switching valve (circulation) sensor SE4 is ON, the residual rice processing When it is determined that the (circulation) control is in effect, and the cut-off sensor SE3 is ON (no wrinkle) and the switching valve (discharge) sensor SE5 is ON, it is determined that the residual rice processing (discharge) control is performed (step S82).

  If it is the normal operation control, it is then determined whether the culm layer thickness sensor SE15 is OFF and the brown rice layer thickness sensor SE14 is ON (step S83). The steep inclination is adjusted (step S84). If the answer is No, it is then determined whether the rice bran layer thickness sensor SE15 is ON and the brown rice layer thickness sensor SE14 is OFF (step S85). If the answer is Yes, the inclination angle of the swing sorting plate 15 is determined. The slope is adjusted to be gentle, and the selection layer thickness is adjusted to be substantially uniform (step S86), and the process returns to step S81.

  Further, when the operation mode is determined (step S82) and the residual rice processing (circulation) control is performed (step S82), and when the cocoon layer thickness sensor SE15 is OFF (step S87), The inclination angle is adjusted to a steep inclination (step S88), and the hulling operation is continued while adjusting the inclination angle to a steep inclination so that the grains are distributed on the lower side 15d of the swing sorting plate 15 (step S88). Return to step S81.

  If the residual rice processing (discharge) control is performed (step S82), and the brown rice layer thickness sensor SE14 is OFF (step S89), the tilt angle of the swing sorting plate 15 is adjusted to a gentle tilt, and the swing sorting is performed. The hulling operation is continued while adjusting the slant so that the grains are distributed on the rocking side 15c of the plate 15 (step S90), and the process returns to step S81.

  In the final stage of the hulling operation, the supply of the hull wastes and the hulls with branching branches increases from the drier and the hail storage tank, and the flow of hulls from the hull hopper 6 to the hulling rolls 7 and 7 often worsens. For this reason, the detection of broken rice in the broken rice sorting SE3 is delayed, and the residual rice processing control may be started in a state where the amount of circulating grains in the machine of the rice hull sorter is small. In such a case, the amount of grain is insufficient, and the rice bran in the residual rice cannot be reduced to the hulling rolls 7 and 7, thus causing a problem that the processing of the residual rice does not end indefinitely.

  However, according to the above configuration, in the residual rice treatment (circulation) control, the thickness of the brown rice layer on the swaying side 15c of the swaying sorting plates 15,. The remaining rice can be circulated while reliably reducing the grains to the hulling portion 1. Further, in the residual rice processing (discharge) control, the brown rice can be discharged quickly by securing the brown rice layer thickness of the rocking side 15c of the swing sorting plates 15,.

Next, another embodiment of control of the hull sorter will be described with reference to FIGS.
As shown in FIG. 13, a grain sorter 51 is disposed in the subsequent process of the rice hull sorter, and the brown rice milling machine 5 of the rice hull sorter supplies the sorted brown rice to the grain sorter 51 for grain sorting. The small rice is separated and removed, and the refined brown rice is taken out. Next, the brown rice lifting machine 52 stores the polished brown rice in the brown rice storage tank 53, and the storage brown rice is measured by the weighing machine 54 and shipped. Further, the take-out hopper 5a of the brown rice cerealing machine 5 is provided with a clogging sensor SE11 so that the clogged state of the brown rice in the grain hopper 51a of the grain sorting machine 51 can be detected.

  As shown in FIG. 14, the clogging sensor SE11, the switching valve (circulation) sensor SE4 and the switching valve (discharge) sensor SE5 are connected to the input side of the controller 41, and the circulation side drive circuit is connected to the output side. The circulation / discharge switching motor M4M4 is connected via a discharge side drive circuit, and the swing motor M3 is connected via a start circuit and a stop circuit.

  As shown in FIG. 15, when the control is started, it is determined whether or not the clogging sensor SE11 is ON (step S41). If Yes, the swing motor M3 of the hulling sorter is stopped, The circulation / discharge switching valve 31 is switched to the circulation side (step S42), and an abnormality is notified by a buzzer (not shown) (step S43).

  When the clogging sensor SE11 is turned off (step S44), the swing motor M3 is driven to start swinging of the swing sorting plate 15, and the circulation / discharge switching valve 31 is switched to the discharge side (step). S45), the abnormality notification is stopped (step S46).

  In the conventional apparatus, when the brown rice masher 5 of the rice hull sorter becomes clogged, the power on / off switch of the operation panel is turned off, the main motor M and the swing motor M3 are stopped, and the rice hull sorting work is stopped. Was. However, in such a configuration, the main motor is stopped, and the rice hull portion 1 of the rice hull sorter, the sliding rice wind selection portion 2, the mixed rice hulling machine 4 and the brown rice hulling machine 5 are stopped, and thus restarted. There was a problem that the restart operation of the hulling roll took time during work, and the work could not be resumed quickly.

  However, according to the above configuration, when the brown rice cerealing machine 5 of the rice hull sorter is clogged due to an overflow due to a failure of the grain sorter 51, the swing sorting plates 15,. Since the oscillation can be stopped, the circulation / discharge switching valve 31 can be switched to the circulation side, and the main motor M1 can be rotated to stand by, so that the operation can be resumed quickly while preventing the rice from being mixed into the brown rice. Can do.
