The valve 51 is configured to excite the extraordinary electromagnetic solenoid so as to switch the valve 51 to the second position (b) at the neutral position of the switch 68 and to the third position (c) at the left rotation position of the switch 68.

As described above, since the air valve 51 can be switched by operating the valve switch 68 of the operator, the remaining rice can be appropriately treated according to the progress of the work. For example, when processing the remaining rice in the mixing rice elevator 4, the valve switch 68 is rotated to the left from the second position (c) in the neutral position to switch the air valve 51 to the third position (c). Then, air can be ejected from the first air nozzle 40 and the second air nozzle 43 via the second connecting hose 42b, and the remaining rice in the lower part of the mixed rice elevator 4 can be treated. On the other hand, when processing the remaining rice in the finished rice elevator 7, the valve switch 68 is rotated to the right from the neutral position (b) to switch the air valve 51 to the first position (c), so that the first connection hose 42a Air can be ejected from the third air nozzle 45 and the fourth air nozzle 46 via the above, and the residual rice in the mixed rice transfer gutter 35 and the residual rice in the lower part of the finished rice elevator 7 can be processed.

The valve switch 68 as a switching operation means of the air valve 51 is rotated so as to supply the air nozzles 45 and 46 to the mixed rice elevator 4 to the left and right sides at the center of the neutral position and the air nozzles 40 to the finished rice elevator 7 to the left and right sides. Since it is a dynamic operation, the air valve 51 as a switching operation means can be configured while operating the operation panel 62, and the operation while operating the operation panel 61 can be facilitated.

The operation panel 62 and the valve switch 68 as a switching operation means are provided on the front side of the machine body, of which the operation panel 62 is arranged between the paddy device 2 and the wind selection unit 3 in front view, and the valve switch 68 is Arranged between the operation panel 62 and the paddy device 2, that is, the valve switch 68 is arranged on the left side of the operation panel 62 in the illustrated example, and the mixed rice elevator is operated by rotating the valve switch 68 from the neutral position to the left. Since the direction of the rotation operation is set so that air is blown to the finished rice elevator 7 by the rotation operation from the neutral position to the right to 4, the two elevators 4 and 7 are aligned at the arrangement position. Easy to see. In this case, the "circulation" lamp L2 at the second operation position and the "discharge" lamp L3 at the third operation position are used by operating the operation lever 55. That is, when the air is ejected to the mixed rice elevator 4, the "circulation" lamp L2 is turned on, and when the air is ejected to the finished rice elevator 7, the "discharge" lamp L3 is turned on so that the operator can clean any part. You can check if it is in mode operation.

Next, based on FIG. 15, the air ejection control in the residual rice processing step at the end of the paddy sorting work will be described. When the operation switch is turned on, the main motor 25 is turned on and each part of the device is driven (S101, S102). When the operation lever 55 in the first operation position is moved to the second operation position, the paddy shutter valve 57 opens and the paddy sorting operation is started (S103, S104).

The mixed rice of paddy brown rice that has been removed for a while circulates in the machine, and when it is detected that a predetermined weight is accumulated in the mixed rice tank 5, the circulation / discharge switching valve 59 switches to the discharge side, and the selected brown rice is finished. It is taken out of the machine via the rice elevator 7 (S105 to S108).

When the paddy sorting work is nearing the end and the weight of the mixed rice tank 5 becomes less than a predetermined weight, the circulation / discharge switching valve 59 is switched to the circulation side and the residual rice processing operation is started (S109 to S111). That is, when the circulation / discharge switching valve 59 is switched to the circulation side, the residual paddy circulates in the machine and is returned to the paddy device 2 for removal processing, and after a predetermined time elapses, the circulation / discharge switching valve 59 is returned to the discharge side. After being switched, the remaining rice is discharged to the outside of the machine via the finished rice elevator 7 (residual rice processing operation, S109 to S114).

Then, during the in-flight circulation of the remaining rice and until a predetermined time elapses after the circulation / discharge switching valve 59 is switched to the discharge side, the air valve 51 and the air from the compressor 41 are aired to the second connection hose 42b. The rice is switched to the third position to be supplied, and air is ejected to the mixed rice elevator 4 to dispose of the remaining rice. After that, the rice is switched to the first position (a) for supplying air to the first connecting hose 42a, and air is ejected to the finished rice elevator 7 to dispose of the remaining rice (cleaning mode operation, S115 to S117). During this cleaning mode operation, the configuration is such that continuous air ejection is switched to intermittent air ejection. The continuous ejection can promote the discharge of the residual rice at the bottom of the elevator, and then the intermittent ejection can effectively discharge a small amount of the residual rice. Then, when the cleaning mode operation is completed, the main motor 25 is turned off and the driving of each part of the device is stopped (S118).

When the re-cleaning mode switch 69 is operated after the paddy sorting work is completed, the main motor 25 is turned on and the compressor 41 is driven after performing idle operation in which each part is driven for a predetermined time. Further, the air valve 51 is switched to the third position for supplying air to the second connecting hose 42b, and the mixed rice elevator 4 is ejected with air to treat the remaining rice. After that, the first connecting hose 42a is supplied with air. The position is switched to, and air is ejected to the finished rice elevator 7 to dispose of the remaining rice (re-cleaning mode operation, S119 to S121). At the time of the above-mentioned re-cleaning mode operation, care must be taken in handling the operation lever 55. That is, when the operation lever 55 is returned to the first operation position at the left end of the guide groove 56, the re-cleaning mode operation is restrained. When entering the initial setting mode for executing the gap adjustment of the paddy rolls 2b and 2b, the re-cleaning mode operation can be avoided.

16 shows details about the relationship between the residual rice processing operation of S111 and S112 of FIG. 15, the cleaning mode operation of S115 to S117, and the recleaning mode operation of S119 to S121.

In FIG. 15, the transition to the cleaning mode operation of S115 to S117 may be configured to automatically shift to S115 after the residual rice discharge operation of S114 for each paddy sorting operation, and the operation panel may be configured before the start of operation. This cleaning mode operation may be executed only when the cleaning mode switch 70 provided in 62 is manually operated. The digital display unit 66 is configured so that the remaining time of the cleaning mode operation can be displayed in a count town so that the operator can be notified.

During the cleaning mode operation or the re-cleaning mode operation, the operation switching output of the valve switch 68 for switching the air valve 51 can be automatically executed without the rotation operation of the switch 68. Although the valve switch is shown in FIG. 16, it is a contrasting notation for outputting a signal corresponding to the first position, the second position, or the third position from the control unit, and is a manual valve switch 68 rotation operation. This is a configuration in which signals corresponding to these positions are automatically output to switch and control the air valve 51 without the need for.

The air valve 51 is in the form of a directional control valve operated by an electromagnetic operation, but it is in the form of a switching valve operated by a mechanical spool operation, and this switching valve and a switching operating tool that replaces the valve switch 68 are mechanically interlocked and connected by wires, rods, or the like. You may. In short, the switching valve that can be switched to the first position, the second position, or the third position may be configured to be interlocked by an electrically or mechanically interlocking switching operating means.

As described above, since the cleaning mode operation and the re-cleaning mode operation are provided, no residual rice is left on the bottom of the mixed rice elevator 4 or the bottom of the finished rice elevator 7. By the way, the air ejection time is configured to be changeable, and depending on the grain varieties to be sorted by paddy, for example, the standard time is set for glutinous rice, but the air ejection time is lengthened for bare wheat. Since the adhesion of dust is remarkable in bare wheat, it is possible to improve the removal of foreign substances mixed in by lengthening it.
