The aforementioned compressor 41 is installed on the front side of the body of the rice hulling and sorting machine 1, and the front cover 49 on the front side of the body is connected to the compressor 41 in series with an air filter 50 and an air valve 51. From the air valve 51 where the supply of air is switched off, two branches are connected to the first connecting pipe 42a and the second connecting pipe 42b. Among them, the first connecting pipe 42a is connected to the aforementioned third air nozzle 45 and the fourth air nozzle through a midway branch. Air nozzle. On the other hand, the second connecting pipe 42b extends to the back of the body and is connected to the first air nozzle 40 and the second air nozzle 43 described above. In addition, the air valve 51 is one form of the switching unit, but adopts an electromagnetically operated directional control valve form as described later.

An operating lever 55 is provided on the front of the winnowing part 3, and the guide groove 56 in the left-right direction is provided so as to be freely operated back and forth. If the operating lever 55 is operated to the first operating position at the left end of the guide groove 56, it is in the start/stop state, the rice gate valve 57 is switched to the closed state, the swing drive unit 58 is switched to the off state, and the cycle/ The discharge switching valve 59 is switched to the circulation state, and the "start/stop" lamp L1 lights up. In addition, when the operating lever 55 is switched to the second operating position of the middle portion of the guide groove 56 in the left-right direction, the rice gate valve 57 is switched to the open state, the swing drive unit 58 is switched to the driving state, and the circulation/discharge switching valve 59 is switched Switch to the loop state, the "loop" lamp L2 lights up. In addition, if the operating lever 55 is switched to the third operating position at the right end of the guide groove 56, the rice gate valve 57 is switched to the open state, the swing drive unit 58 is switched to the driving state, and the circulation/discharge switching valve 59 is switched When it reaches the discharge state, the "discharge" lamp L3 lights up.

In addition, the circulation/discharge switching valve 59 is configured to switch the sorting brown rice on the surface of the swing sorting plate 14 to the discharge side of the finished rice elevator 7 via the discharge path 9 and the circulation side to guide the sorting brown rice to the re-sorting path 13 side. . If there are few objects to be selected on the surface of the swing sorting plate 14, the rice will be mixed into the refined brown rice. Therefore, the circulation/discharge switching valve 59 is switched to the circulation side, and the reselection path 13 returns to the swing sorting plate via the mixed rice elevator 4 14, and a part of it can be returned to the rice shelling device 2 via the re-hulling path 12, combined with the re-hulling step, the remaining rice can be hulled and sorted. As shown in FIG. 13, the circulation/discharge switching valve 59 is configured to be switched by the circulation/discharge switching motor M1. In addition, the operating lever 55 and the circulation/discharge switching valve 59 are interlocked by the circulation/discharge operation wire 60, and are interlocked so that the paddy gate valve 57, the swing access pulley 61, and the circulation/discharge switching are operated by the operation lever 55. The valve 59 performs a switching operation.

The gap adjustment of the shelling rolls 2b and 2b is configured to be performed by the drive of the roll gap adjustment motor M2.

An operation panel 62 is provided on the upper center of the front of the rice hulling and sorting machine. A power on/off switch 63, an operation switch 64, a stop switch 65, etc. are provided on the left and right sides of the operation panel 62 (the right side in the illustration). A digital display unit 66 and a display switch 67 are provided on the upper side of the operation panel 62.

A valve switch 68 for switching the air valve 51 is provided on one side of the operating panel 62 and the operating lever 55 in the front view, on the left side in the illustration and close to the guide groove 56 of the operating lever 55. The aforementioned air valve 51 not only switches the supply and stop of air, but also has a function of switching the direction of supplying air to the first connecting pipe 42a side or the second connecting pipe 42b side, and is configured to be switchable to the first connecting pipe 42a side or the second connecting pipe 42b side. The electromagnetically operated directional control valve forms at the first position where air is supplied to the one connecting pipe 42a, the second neutral position where the air supply is stopped, and the third position where air is supplied to the second connecting pipe 42b. Furthermore, a structure in which the valve switch 68 is rotated from the neutral position in the center to the right or left to switch between three positions is adopted to switch the aforementioned air valve 51 to the first position (A) at the right rotation position of the valve switch 68. In the neutral position of the valve switch 68, the air valve 51 is switched to the second position (B), and the air valve 51 is switched to the third position (C) at the left-hand rotating position of the valve switch 68, using a solenoid (not shown) The structure of solenoid excitation.

As described above, the air valve 51 can be switched by the operator operating the valve switch 68, so that the remaining rice treatment can be appropriately performed in accordance with the progress of the work. For example, when processing the remaining rice of the mixed rice elevator 4, the valve switch 68 is turned to the left from the second position (B) of the neutral position to switch the air valve 51 to the third position (C). Accordingly, air can be ejected from the first air nozzle 40 and the second air nozzle 43 through the second connecting pipe 42b, and the remaining rice in the lower part of the mixed rice elevator 4 can be processed. On the other hand, when processing the remaining rice of the finished rice elevator 7, the valve switch 68 is turned to the right from the second position (B) to switch the air valve 51 to the first position (A), thereby enabling the A connecting pipe 42a ejects air from the third air nozzle 45 and the fourth air nozzle, and can handle the remaining rice in the mixed rice transfer trough 35 and the remaining rice in the lower part of the finished rice elevator 7.

The valve switch 68, which is a switching operation unit of the air valve 51, is operated as follows: with the neutral position as the center, it is supplied to the air nozzle 45 of the hybrid rice elevator 4 when it is rotated to one of the left and right, and supplied to the other of the left and right. Up to the air nozzle 40 of the finished rice elevator 7, the operation panel 62 can be configured and the air valve 51 as a switching operation unit can also be operated, and the operation while operating the operation panel 62 can be facilitated.

An operation panel 62 and a valve switch 68 as a switching operation unit are provided on the front side of the machine body. Among them, in the front view, the operation panel 62 is arranged between the rice dehulling device 2 and the winnowing unit 3, and the valve switch 68 is arranged Between the operation panel 62 and the rice dehulling device 2, that is, in the example of the figure, a valve switch 68 is arranged on the left side of the operation panel 62, and the direction of the rotation operation is set by the neutral position of the valve switch 68 The leftward turning operation ejects air to the mixed rice elevator 4, and the rightward turning operation from the neutral position ejects air to the finished rice elevator 7, so the rice elevator 4 is mixed with two elevators. The arrangement positions of the elevators 7 are consistent and easy to visually confirm. In addition, in this case, the "recycle" lamp L2 at the second operation position and the "discharge" lamp L3 at the third operation position are used by the operation of the aforementioned operation lever 55. That is, when the air is sprayed to the hybrid rice elevator 4, the "recirculation" lamp L2 is turned on, and when the air is sprayed to the finished rice elevator 7, the "discharge" lamp L3 is turned on, so that the operator can confirm which part of the cleaning mode is Running.

Next, based on FIG. 15, the gas ejection control in the remaining rice processing step at the end of the hulling and sorting operation will be described. When the operation start is turned on, the main motor 25 is turned on, and each part of the device is driven (S101, S102). When the operating lever 55 located in the first operating position is moved to the second operating position, the rice gate valve 57 is opened, and the hulling and sorting operation is started (S103, S104).

The mixed rice of rice and brown rice that has been shelled for a certain period of time is circulated in the equipment. If a predetermined weight is detected in the mixed rice container 5, the circulation/discharge switching valve 59 is switched to the discharge side, and the selected brown rice is passed through the refined The processed rice elevator 7 is taken out of the equipment (S105 to S108).

When the hulling and sorting operation is nearing completion and the mixed rice container 5 has a predetermined weight or less, the circulation/discharge switching valve 59 is switched to the circulation side, and the remaining rice processing operation is started (S109 to S111). That is, if the circulation/discharge switching valve 59 is switched to the circulation side, the remaining rice circulates in the equipment and returns to the rice shelling device 2 for hulling treatment. When a predetermined time has elapsed, the circulation/discharge switching valve 59 switches to discharge again On the other hand, the remaining rice is discharged to the outside of the equipment via the refined rice elevator 7 (remaining rice processing operation, S109 to S114).

Then, during the aforementioned internal circulation of the remaining rice and until a predetermined time has elapsed after the circulation/discharge switching valve 59 is switched to the discharge side, the air valve 51 is switched to supply air from the compressor 41 to the second connecting pipe 42b In the third position, air is sprayed to the mixed rice elevator 4 for residual rice treatment. Then, it switches to the first position (A) where air is supplied to the first connecting pipe 42a, and blows air to the finished rice elevator 7 to perform residual rice processing (cleaning mode operation, S115 to S117). It is configured to switch from continuous air ejection to intermittent air ejection during operation in this cleaning mode. The continuous spraying can promote the discharge of the remaining rice at the bottom of the elevator, and then the intermittent spraying can effectively discharge a small amount of the remaining rice. Then, when the cleaning mode operation ends, the main motor 25 is turned off (OFF), and the driving of each part of the device is stopped (S118).

Once the dehulling and sorting operation is completed, if the re-cleaning mode switch 69 is operated, the main motor 25 is turned on, and the compressor 41 is driven after the idling operation of each part of the drive for a predetermined time. Then, the air valve 51 is switched to the third position for supplying air to the second connecting pipe 42b, and air is sprayed to the hybrid rice elevator 4 for residual rice processing, and then switched to the first position for supplying air to the first connecting pipe 42a , Air is blown to the finishing rice elevator 7 to perform residual rice treatment (re-cleaning mode operation, S119 to S121). When operating in the aforementioned re-cleaning mode, it is necessary to pay attention to the operation method of the operating lever 55. That is, the structure is When the operation lever 55 is restored to the first operation position at the left end of the guide groove 56, the re-cleaning mode operation is restricted. When entering the initial setting mode in which the gap adjustment of the shelling rollers 2b and 2b is performed, the operation in the re-cleaning mode can be avoided.

In addition, FIG. 16 shows in detail the relationship between the remaining rice processing operation of S111 and S112 of FIG. 15, the cleaning mode operation of S115 to S117, and the re-cleaning mode operation of S119 to S121.

In FIG. 15, the transition to the cleaning mode operation from S115 to S117 can be configured to automatically transfer the mode to S115 after the remaining rice discharge operation of S114 during each hulling and sorting operation, or it can be configured to only operate This cleaning mode operation is executed when the cleaning mode switch 70 provided on the operation panel 62 is manually operated before the start. The aforementioned digital display unit 66 is configured to be able to count down and display the remaining time of the cleaning mode operation, 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 that switches the aforementioned air valve 51 is not automatically performed based on the turning operation of the valve switch 68. In FIG. 16, although the valve switch is marked, it is only a comparison mark for outputting a signal corresponding to the first position, the second position, or the third position from the control unit. The valve switch 68 is configured to be operated even without manual rotation. , The signals matching these positions are still automatically output to switch and control the air valve 51.

Although the air valve 51 is set as a solenoid-operated directional control valve form, it is also possible to adopt a switching valve form based on mechanical spool operation, and the switching valve and the switching operation device of the replacement valve switch 68 can be made of metal wires, linkages and other mechanical devices. Linked to the ground. In short, what is necessary is just to be structured so that the switching valve which can be switched to the said 1st position, the 2nd position, or the 3rd position is interlocked by the switching operation unit which communicates electrically or mechanically.

As described above, since the cleaning mode operation and the re-cleaning mode operation are provided, no residual rice remains at the bottom of the mixed rice elevator 4 or the bottom of the refined rice elevator 7. However, for air jets The time is configured to be changeable. Depending on the type of grain to be selected for hulling, for example, japonica rice is set as the standard time, but for highland barley, the air blowing time is extended. In the case of highland barley, the adhesion of dust is significant, so increasing the air ejection time can improve the removal of mixed foreign matter.
