A brown rice region A of a brown rice layer is formed on the shaking side of the swinging sorting plate 14, a paddy region B of a paddy layer is formed on the shaking side, and a mixed rice region C of a mixed rice layer is formed in the middle part.

A paddy guide port 17 for taking out the paddy from the paddy region B is provided on the side of the sorting end side T of the paddy region B for each swing sorting plate 14 of the swing sorting device 6. A box-shaped paddy/brown rice separator 16 is attached to the opposing position via the side plate 14a. The paddy from the paddy region B of each swing sorting plate 14 flows into the paddy/brown rice separator 16 through the paddy guide port 17, where the brown rice mixed with the paddy is separated and the paddy is transferred to the re-hulling path 12. It is configured to guide the brown rice to the re-sorting path 13.

Inside the paddy/brown rice separator 16, there are provided perforated plates 16a as many as the number of stages of the oscillating sorting plates 14, each having a large number of perforated holes which are mesh bodies through which the brown rice mixed with the paddy leaks. A brown rice guide plate 16b is provided below each perforated plate 16a to receive brown rice that has been sorted out. That is, the porous plate 16a and the brown rice guide plate 16b are arranged alternately in the vertical direction.

A brown rice guide passage 18 is provided on the brown rice discharge side of the brown rice guide plate 16b, through which the brown rice discharged from each brown rice guide plate 16b is collectively guided, and this brown rice guide passage 18 is communicated with the re-sorting passage 13. In addition, a paddy guide passage 19 is provided to collectively guide the paddy that has not leaked through the perforated plates 16a of each stage, and the paddy guide passage 19 and the re-hulling passage 12 are communicated with each other.

In this embodiment, the brown rice guide passage 18 is arranged on the side of the brown rice guide plate 16b, and the paddy guide passage 19 is arranged on the front side of the perforated plate 16a.

Each perforated plate 16a and the brown rice guide passage 18 are partitioned by a paddy partition wall 16S, the brown rice guide plate 16b and the brown rice guide passage 18 are configured to communicate with each other, each perforated plate 16a and the paddy guide passage 19 are communicated with each other, and the brown rice guide plate 16b and the paddy guide passage 19 are separated by a brown rice partition wall 16G. That is, a perforated plate 16a, a brown rice guide plate 16b, a paddy guide passage 19, a brown rice guide passage 18, a paddy partition wall 16S, and a brown rice partition wall 16G are provided in the box body of the paddy/brown rice separator 16.

Paddy from the paddy area B flows into the perforated plate 16a of the paddy/brown rice separator 16 from the paddy guide port 17 provided for each multistage swing sorting plate 14. The mixed brown rice leaks through the perforated plate 16a, and the paddy remaining on the perforated plate 16a flows into the paddy guide path 19 while being blocked from flowing into the brown rice guide path 18 by the paddy partition wall 16S, and is re-hulled. He falls onto Road 12 and is guided. Further, the brown rice that has leaked through the perforated plate 16a falls onto the brown rice guide plate 16b and is supplied, and while being prevented from flowing into the paddy guide passage 19 by the brown rice partition wall 16G, it enters the brown rice guide passage 18, falls, and is re-sorted. You will be guided to Route 13. With this configuration, the brown rice mixed with the paddy taken out from the paddy area B can be accurately sorted by sorting each stage without stagnation.

In this case, by providing the paddy/brown rice separator 16 along the outside of the side plate 14a and forming a long sorting process using the long perforated plate 16a in the front-rear direction, it is possible to improve the accuracy of sorting the paddy and brown rice. The amount of brown rice that returns to the sliding device 2 is reduced, and the amount of brown rice that is rubbed twice can be reduced. Further, the sorted brown rice can be quickly re-sorted through the re-sort path 13.

In addition, each brown rice guide plate 16b is provided with an inclination angle that sends the brown rice to the brown rice guide passage 18 side below the perforated plate 16a of the paddy guide port 17, so that the leakage sorted grains received from the perforated plate 16a are quickly removed. This enables efficient re-sorting without stagnation. Further, the perforated plate 16a is provided in a position parallel to the swinging sorting plate 14, and is configured to be inclined forward and downward in the front-rear direction like the swinging sorting plate, so that the paddy can be smoothly discharged into the paddy guide path 19.

The distribution receiving section 15 is provided below the mixed rice tank 5, and transfers the mixed rice from the mixed rice tank 5 from the back side of the multi-stage oscillating sorting plate 14 to each stage through a wide transfer gutter section 15a. It supplies the water to the distribution gutter 14d. In order to separate the long foreign matter D mixed in the mixed rice, the receiving part perforated plate 20 in which perforated holes 20a are formed is placed in a horizontal position in the distribution receiving part 15 shown in the transparent front view including the partial arrow view of FIG. A side discharge port 21 for discharging the elongated foreign matter D to the side is formed facing the discharge end thereof. Between the discharge end of the perforated receiver plate 20 and the side discharge port 21, there is a perforated sorting plate 22 formed with perforations 22a for leaking mixed rice and supplying it to the uppermost swinging sorting plate 14. establish. The perforated holes 22a are formed over the entire width at least on the discharge end side of the perforated receiving plate 20. Most of the mixed rice leaks from the perforated receiving plate 20 into the transfer gutter 15a and is transferred toward the distribution gutter 14d, and a transfer rack may be formed in the transfer gutter 15a as appropriate. A leveling valve 23 for flow rate adjustment is provided on the swinging side of the distribution receiving part 15 so that the amount of flow from the distribution gutter 14d to the swinging sorting plates 14 at each stage can be made uniform. Further, the subsequent sorting section perforated plate 22 has a short section, but is inclined slightly upward toward the side discharge port 21, so that the remaining mixed rice leaks out while delaying the transfer of the long foreign matter D.

The perforated receiving plate 20 configured as described above distributes and supplies the mixed rice received from the mixed rice tank 5 to each of the oscillating sorting plates 14 by leaking it to the mixed rice flow down plate 15a below by a oscillating operation, and The elongated foreign matter D in the mixed rice remaining on the perforated receiving plate 20 is transferred to the terminal end side by the rocking. The long foreign matter D further moves to the perforated plate 22 of the sorting section, and the mixed rice mixed with the long foreign matter D leaks out and is supplied to the uppermost swinging sorting plate 14. It is discharged from the discharge port 21. Therefore, with the simple configuration of the perforated receiving plate 20 and the perforated sorting plate 22, the elongated foreign matter D such as straw waste can be sequentially discharged.

In this case, by arranging the sorting section perforated plate 22 at a position facing the uppermost swinging sorting plate 14, mixed rice can be fed to the swinging sorting plate 14 without the need for a special guide member. can. Further, by forming the perforated sorting plate 22 so as to rise upward to the side discharge port 21, the movement of the elongated foreign matter D is suppressed, and the mixed rice can be reliably leaked out.

The foreign object receiver 21D, which receives the elongated foreign object D from the side outlet 21, is oscillated at a position directly below the side outlet 21, as shown in the exploded perspective view (a) and main part side view (b) of FIG. A receiving plate portion 24b is openably provided in an opening formed in a projecting portion 24a of an exterior cover 24 that covers the rear side of the dynamic sorting plate 14. That is, the receiving plate portion 24b forms a part of the exterior cover 24.

This foreign object receiver 21D prevents foreign objects from entering from the outside when closed by pivotally supporting the receiving plate 24b so as to be openable with a hinge or the like, and also prevents foreign objects from entering from the outside when the foreign object receiver 21D is closed. Foreign matter D is received from the side discharge port 21 and stored. By rotating and opening the receiving plate part 24b at a side position of the machine body, the accumulated foreign matter D can be dropped and discharged outside the machine by using the receiving plate part 24b as an inclined guide. The stored foreign matter D can be stored in a housing member (not shown) disposed below without touching it.

In this case, by providing a partition 24c that surrounds the opening formed in the projecting portion 24a, scattering of the foreign matter D received on the receiving plate portion 24b can be prevented.

In the upper part of the swinging sorting device 6, on the front side of the distribution receiving section 15, there is provided an upper cover 71 that covers the top of the swinging sorting plate 14 in the uppermost stage. Further, a front cover 72 is provided so as to be continuous with the upper cover 71 and cover the front surface of the multi-stage swing sorting plate 14. These top cover 71 and front cover 72 are fastened and fixed to the machine frame of the swing sorting device 6. A transparent inspection cover 73 made of transparent resin is provided near the front of the top cover 71 so as to be openable and closable around the rear fulcrum X. On the lower surface of the upper surface cover 71 toward the rear, a middle portion of a dust suction cylinder 74 that sucks dust from the finished rice of the finished rice elevator 7 is supported. That is, the dust suction cylinder 74 made of a flexible material is provided between the throwing port of the finished rice elevator 7 and the suction blower 3b to the rice husk duct 3a of the wind sorting section 3, and is used to collect the finished rice discharged from the finished rice elevator 7. It is configured to collect and remove dust from the air. It is surrounded and supported by an upper cover 71 and a cylindrical support frame 75 fixed to the inner side of the upper cover 71 in a hanging manner by means such as welding. That is, a rectangular cylinder with left and right openings is formed by a cylinder support frame 75 made of a sheet metal material bent to form a pair of front and rear wall members 75f, 75r and a bottom part 75b, and an upper surface cover 71, and a dust suction cylinder. 74 is inserted through it, and its midway portion is supported by a cylindrical support frame 75.

As shown in FIG. 8, a lighting fixture 76 that is long in the swing direction of the swing sorting plate 14, that is, in the left-right direction, is provided on the front wall member 75f of the cylinder support frame 75. The structure is such that the part side, that is, the sorting end side T, can be irradiated from above the swinging sorting plate 14. That is, the lighting fixture 76 uses a light emitting element such as an LED (light emitting diode) as a light source, and has a configuration in which a plurality of LEDs are arranged in series at a predetermined interval in a straight tube-shaped cover, and a wall member 75f has a light emitting device arranged in front of one wall member 75f. The support stay 77 is fixed, and the seating surface of the lighting fixture 76 is fixed and attached to the tip bent at an acute angle. The irradiation direction is directed diagonally downward by an acute angle bend from the mounting position above the swinging sorting plate 14, and is provided so that the sorting end side T of the swinging sorting plate 14 can be irradiated as described above.

Since the illumination device 76 configured as described above directs the irradiation toward the discharge tip of the swinging sorting plate 14, when looking at the surface of the swinging sorting plate 14 from above the swinging sorting plate 14, the The positions of the finishing partition plate 8 and the paddy partition plate 10 relative to the sorting plate 14 can be clearly confirmed, improving visibility.

Note that the lighting fixture 76 is configured to be long in the swinging direction of the swinging sorting plate 14, that is, in the left-right direction, as described above. The longitudinal length of the lighting device 76 and the arrangement configuration of the related plurality of LEDs are set so that the sorting end side T (discharge tip) of the oscillating sorting plate 14 in the brown rice area A can be illuminated beyond the area A. .

Furthermore, since the lighting fixture 76 is provided on the wall member 75f formed on the top cover 71 to support the dust suction cylinder 74, it can be installed using the necessary members for installing the dust suction cylinder 74. This allows for a good installation. If a part of the dust suction cylinder 74 is formed into a sheet metal so as to be replaced by the wall member 75f, it can be directly supported by the dust suction cylinder 74.

As shown in FIG. 8, the transparent inspection cover 73 is formed into a dogleg shape in cross section, and a boss portion 73a integrally molded at the lower rear side is aligned with a shaft support 71a formed on the upper cover 71 so that it can be rotated in the left and right direction. The transparent inspection cover 73 is configured to be able to open and close the opening of the upper cover 71 by being connected by a support shaft 78 having an axis and rotating up and down using the support shaft 78 as a rotation fulcrum X. . There is a distance from the rotational fulcrum X, that is, the boss portion 73a, to the rear end of the transparent inspection cover 73, so that there is no gap between the opening of the top cover 71 and the rear end of the transparent inspection cover 73. There is. Although the lighting fixture 76 and the rotation fulcrum X are close to each other, the position of the lighting fixture 76 is on the rear side of the rotation fulcrum It is located at the back of the bottom. Therefore, even if the transparent inspection cover 73 is opened to inspect the interior, the light from the lighting fixture 76 will not directly enter the eyes.

Next, the dust suction cylinder 74 is connected to the suction blower 3b of the wind selection section 3 to generate dust suction air, and can discharge dust from the rice husk duct 3a. The suction blower 3b of the rice husk duct 3a is equipped with a fan 3c, and at the suction port of the suction blower 3b, intake areas are set for the main air passage of the wind selection section 3 and the suction air passage of the dust suction cylinder 74. This suction area is configured to be changeable, and by increasing the area of the suction air passage on the dust suction cylinder 74 side after completing the hulling sorting work, the suction blower 3b sucks out a lot of dust and rice remaining after the hulling work. The rice husks can be discharged from the rice husk duct 3a.

In FIG. 9, the end configuration of the dust suction cylinder 74 is shown. A dust suction port 7d is configured adjacent to the finished rice discharge port 7c of the throwing port 7a of the finished rice elevator 7, and an insertion tube 74b at the end of the dust suction cylinder 74 is configured to be detachable and retainable in the dust suction port 7d. are doing. When the end of the dust suction cylinder 74 is removed, the rectangular opening 74c of the insertion cylinder 74b can be used as a cleaning opening, which, in conjunction with the flexible cylinder structure, can be used to clean each part of the machine body and the surrounding area.

The transmission structure (FIG. 10) of each part of the hulling and sorting machine by the motor 25 is such that the motor 25 transmits power through the first belt 26 to the roll shaft 2c that pivotally supports the hulling rolls 2b, 2b of the hulling device 2.

It is a form.

Note that the second belt 27 may be divided into two parts. That is, the roll shaft 2c, the sliding rice transfer shelf 28 swing shaft 28a, the mixed rice elevator 4 interlocking shaft 4a are interlocked by the V-belt-shaped divided first belt 27A, the mixed rice elevator 4 interlocking shaft 4a, and the second spiral 29. The shaft 29a, the interlocking shaft 6b of the swing sorting device 6, and the interlocking shaft 7B of the finished rice elevator 7 are interlocked by a divided second belt 27B in the form of a hexagonal belt (FIG. 11). With this configuration, when a load such as clogging is applied to the hulling device 2, the first divided belt 27A slips and the load is not easily applied to the second divided belt 27B.

Next, the mixed rice transfer configuration and the remaining rice processing configuration will be explained based on FIGS. 12 and 13. The mixed rice helix 31 is disposed in the mixed rice transfer gutter 35, receives the washed rice flowing down from the washed rice transfer shelf 28 of the hulling device 2, and the mixed rice from the re-sorting path 13, and collects the mixed rice. It is configured to be transferred to an elevator 4. The mixed rice elevator 4, in which a plurality of buckets 4b, 4b... are attached to an endless belt 4c and wound between upper and lower pulleys 4u, 4d, is located at the rear of the hulling sorter 1 and behind the wind sorting section 3. It will be erected in The transfer end side of the mixed rice transfer gutter 35 is connected to the lower end side of the mixed rice elevator 4. The connecting portion 35a of this mixed rice transfer gutter 35 is fixed to the grain scooping side (lowering process side) of the buckets 4b, 4b, etc., and the mixed rice is transferred in the mixed rice transfer gutter 35 by the rotation of the mixed rice helix 31. The mixed rice is configured to be guided down into the lower part of the elevator 4 from a communication opening to the lower side wall of the elevator 4 for mixed rice.

An opening/closing valve 36 is provided along the conveying direction of the mixed rice transfer gutter 35, and the bottom of the mixed rice transfer gutter 35 can be opened and closed, so that the remaining rice accumulated at the bottom of the transfer gutter 35 can be discharged. A residual rice receiving box 37 is provided below the on-off valve 36 as a residual rice receiving section for receiving discharged residual rice.

The mixed rice elevator 4 is erected at the rear of the hull of the huller and sorter 1 with a space for installing the second belt 27, that is, at an appropriate distance behind the rear cover 38 that covers the back of the hull. The terminal end side of the transfer gutter, which is the connection part 35a of the mixed rice transfer gutter 35, is also located at the rear of the machine body, and the mixed rice transfer gutter 35 has a bottom opening and a corresponding opening/closing valve. 36 is a configuration disposed in a section inside the fuselage.

A first air nozzle 40 is disposed at the bottom of the mixed rice elevator 4. As shown in FIG. 14, the first air nozzle 40 is attached to the side wall opposite to the side to which the mixed rice transfer gutter 35 is connected, and the blast direction (c) of the first air nozzle 40 is It is set diagonally downward toward the bottom of the screen. The first air nozzle 40 is configured to be supplied with compressed air via a connecting hose 42 from a compressor 41 installed in front of the huller 1 body.

As described above, since the first air nozzle 40 is provided, the remaining rice at the bottom of the mixed rice elevator 4 is splashed up by the air jet from the nozzle after the hulling operation is completed, and is scooped up by the buckets 4b, 4b, . . . Can be raised efficiently.

Further, a second air nozzle 43 is provided at the connection portion 35a of the mixed rice transfer gutter 35 with the mixed rice elevator 4. The second air nozzle 43 is attached to the upper wall of the mixed rice transfer gutter 35, and the nozzle blow direction is directed toward the upper direction of transfer, which is opposite to the transfer direction (b) by the mixed rice helix 31. The support body 44 of the second air nozzle 43 is composed of a base plate 44a and an upwardly bulging portion 44c having a nozzle mounting surface 44b, and is inserted into a hole formed in the upper wall portion of the connection portion 35a of the mixed rice transfer gutter 35. It is installed accordingly. The nozzle mounting surface 44b has an angle α with the horizontal surface and determines the blowing direction (a) of the second air nozzle 43.

Since the second air nozzle 43 is provided in this manner, after the hulling sorting operation is completed, while the mixed rice spiral 31 and the mixed rice elevator 4 are being driven, the on-off valve 36 is opened to blow out air from the second air nozzle 43. As a result, the mixed rice that is about to be transferred to the transfer end side of the mixed rice transfer gutter 35 can be collected into the remaining rice receiving box 37 through the opening provided by the on-off valve 36. Since the connection part 35a of the mixed rice transfer gutter 35 does not include the on-off valve 36, the remaining rice is moved to the location where the on-off valve 36 is present by air jet in the opposite direction to the transfer direction by the second air nozzle 43. It is possible to reduce the amount of leftover rice as much as possible.

Further, a third air nozzle 45 is provided on the starting end side of the mixed rice transfer gutter 35 toward the mixed rice transfer direction, and a fourth air nozzle 46 is provided at the lower part of the finished rice elevator 7. The third air nozzle 45 promotes discharge of the remaining rice in the mixed rice transfer gutter 35 downward from the on-off valve 36. Furthermore, since the inspection cover 47 is attached to the front of the machine body, inspection and replacement work can be easily performed. A support portion 48 having a base plate 48a and a nozzle mounting surface 48b is mounted. Then, the fourth air nozzle 46 splashes up the remaining rice at the bottom of the finished rice elevator 7 to increase the efficiency of scraping up the bucket.

Here, the air hose to the third air nozzle 45 on the mixed rice elevator 4 side and the air hose to the fourth air nozzle 46 on the finished rice elevator 7 side are the air hoses to the mixed rice elevator 4 side where the amount of remaining rice and bran is relatively large. The diameter of the air hose is set to be large (for example, φ8 mm), and the diameter of the air hose to the finished rice elevator 7 side is set to be small (for example, φ6 mm). By making the diameters of the air hoses different, so-called incorrect assembly can be prevented.

The compressor 41 is installed on the front side of the huller 1 body, and an air filter 50 and an air valve 51 are connected in series to the compressor 41 to a front cover 49 on the front side of the body. An air valve 51 that switches the air supply stop is branched into two to connect a first connection hose 42a and a second connection hose 42b, and among these, the first connection hose 42a is connected to the third air nozzle through a branch part in the middle. 45 and a fourth air nozzle 46. On the other hand, the second connection hose 42b is extended to the back of the aircraft body and connected to the first air nozzle 40 and the second air nozzle 43. The air valve 51 is one form of switching means, and is in the form of an electromagnetically operated directional control valve as will be described later.

Although the air filter 50 can be attached to the aircraft body arbitrarily, it can also be placed on the left side of the operating section that includes the operating lever 55 and the like. Improves maintainability. Further, by arranging the air filter 50 near the location where the power supply harnesses (not shown) of the aircraft body are arranged, the arrangement of the power supply harnesses can be utilized and the arrangement becomes easy. When the air valve 51 is constructed mechanically as described below, it is convenient for the air filter 50 to be at a lower height than the air valve 51.
A connecting hose connecting the air filter 50 and the air valve 51 is arranged inside the removable body cover. Maintenance and cleaning performance can be improved.

As shown in FIG. 15, an operating lever 55 is provided in front of the wind selection section 3, and is provided so as to be reciprocally operable along a guide groove 56 in the left and right direction. When the operating lever 55 is operated to the first operating position at the left end of the guide groove 56, the start/stop state is established, the paddy shutter valve 57 is closed, the swing drive device 58 is turned off, and the circulation/discharge switching valve is in the start/stop state. 59 switches to a circulating state, and the "start/stop" lamp L1 lights up. Furthermore, when the operating lever 55 is switched to the second operating position at the middle part in the left-right direction of the guide groove 56, the paddy shutter valve 57 is opened, the swing drive device 58 is set to the driven state, and the circulation/discharge switching valve 59 is set to the circulating state. Switching, the "circulation" lamp L2 lights up. Furthermore, when the operating lever 55 is switched to the third operating position at the right end of the guide groove 56, the rice shutter valve 31 is switched to the open state, the swing drive device 32 is switched to the driven state, and the circulation/discharge switching valve 59 is switched to the discharge state. , the "ejection" lamp L3 lights up.

The circulation/discharge switching valve 59 has a discharge side that guides the sorted brown rice on the surface of the oscillating sorting plate 14 to the finished rice elevator 7 via the discharge path 9, and a circulation side that guides the sorted brown rice to the re-sorting path 13 side. It is configured to switch between When the number of materials to be sorted on the oscillating sorting plate 14 decreases, paddy will be mixed into the finished brown rice, so the circulation/discharge switching valve 59 is switched to the circulation side and the oscillating sorting plate is passed from the re-sorting path 13 to the mixed rice elevator 4. 14, a part of the rice can be returned to the hulling device 2 via the re-hulling path 12, and in combination with the re-hulling process, the remaining rice can be processed for shedding and sorting. As shown in FIG. 16, this circulation/discharge switching valve 59 is configured to be switched by a circulation/discharge switching motor M1. Further, the operation lever 55 and the circulation/discharge switching valve 59 are interlocked and connected by a circulation/discharge operation wire 60, and the operation of the operation lever 55 switches the paddy shutter valve 57, the swinging cut-off pulley 61, and the circulation/discharge switching valve 59. It is configured to be operated in conjunction with each other.

The gap adjustment between the hulling rolls 2b, 2b is configured to be performed by driving a roll gap adjustment motor M2.

An operation panel 61 is provided at the upper center of the front of the rice huller and sorter. A power on/off switch 63, a run switch 64, a stop switch 65, and the like are provided on one of the left and right sides (the right side in the illustrated example) of the operation panel 61. A digital display section 66 and a display changeover switch 67 are provided on the upper side of the operation panel 34.

A valve switch 68 for switching the air valve 51 is provided on one side of the operation panel 61 and the operation lever 55 when viewed from the front, at a position close to the guide groove 56 of the operation lever 55 on the left side in the illustrated example. The air valve 51 has a function of not only switching between supplying and stopping air but also switching the direction to supply air to the first connection hose 42a side or the second connection hose 42b side, and supplies air to the first connection hose 42a. The first position is a neutral second position where air supply is stopped, and the third position is a neutral position where air is supplied to the second connection hose 42b. The valve switch 68 is configured to be switched to three positions by rotating from the central neutral position to the right or left, and when the switch 68 is rotated to the right, the air valve 51 is placed in the first position (A). When the switch 68 is in the neutral position, the valve 51 is switched to the second position (B), and when the switch 68 is rotated to the left, the valve 51 is switched to the third position (C), so that an electromagnetic solenoid (not shown) is energized. (See Figure 17).

As described above, since the air valve 51 can be switched by the operator's operation of the valve switch 68, the remaining rice can be appropriately disposed of according to the progress of the work. For example, when disposing of leftover rice in the mixed rice elevator 4, the valve switch 68 is rotated leftward from the neutral second position (c) 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 connection hose 42b, and the remaining rice at the bottom of the mixed rice elevator 4 can be disposed of. On the other hand, when disposing of the remaining rice in the finished rice elevator 7, the air valve 51 is switched to the first position (c) by rotating the valve switch 68 from the neutral position (b) to the right, and the first connection hose 42a Air can be ejected from the third air nozzle 45 and the fourth air nozzle 46 via the air nozzle 45, and the remaining rice in the mixed rice transfer gutter 35 and the remaining rice in the lower part of the finished rice elevator 7 can be disposed of.

A valve switch 68 serving as a switching operation means for the air valve 51 is rotated so that the air nozzles 45 and 46 to the mixed rice elevator 4 are supplied to the left and right sides, and the air nozzles 40 to the finished rice elevator 7 are supplied to the left and right sides with the neutral position at the center. Since it is operated manually, the air valve 51 can be configured as a switching operation means while operating the operating panel 62, and the operation while operating the operating panel 61 can be facilitated.

An operation panel 62 and a valve switch 68 as a switching operation means are provided on the front side of the machine. Among these, the operation panel 62 is arranged between the hulling device 2 and the wind selection section 3 when viewed from the front, and the valve switch 68 is A valve switch 68 is disposed between the operation panel 62 and the hulling device 2, that is, on the left side of the operation panel 62 in the illustrated example, and by rotating the valve switch 68 from the neutral position to the left, the mixed rice elevator is activated. 4, since the direction of the rotation operation is set so that air is spouted to the finished rice elevator 7 by the rotation operation from the neutral position to the right, the two elevators 4 and 7 are arranged in the same position. Easy to see. In this case, by operating the operating lever 55, the "circulation" lamp L2 at the second operating position and the "discharge" lamp L3 at the third operating position are utilized. In other words, the "circulation" lamp L2 is turned on when air is ejected to the mixed rice elevator 4, and the "discharge" lamp L3 is turned on when air is ejected to the finished rice elevator 7. You can check whether the mode is running.

Furthermore, the lighting device 76 may be configured to blink in place of or simultaneously with the "circulation" lamp L2 and the "discharge" lamp L3. Air jet timing can be clarified and air can be supplied at appropriate timing. It should be noted that a configuration may be adopted in which the air supply to the mixed rice elevator 4 and the air supply to the finished rice elevator 7 can be notified separately. By varying the flashing modes of the lighting fixtures 76, it is possible to differentiate them by, for example, the difference in flashing cycle, and it is possible to determine which elevator is being supplied with air, thereby improving work efficiency.

Next, based on FIG. 18, air blowout control in the remaining rice processing process at the end of the hulling and sorting work will be described. When the operation switch is turned on, the main motor 25 is turned on and each part of the apparatus is driven (S101, S102). When the operating lever 55 from the first operating position is moved to the second operating position, the rice shutter valve 57 is opened and the hulling and sorting operation is started (S103, S104).

The mixed rice of unhulled unhulled rice is circulated in the machine for a while, and when it is detected that a predetermined weight has accumulated in the mixed rice tank 5, the circulation/discharge switching valve 59 is switched to the discharge side, and the sorted brown rice is finished. The rice is taken out of the machine via the rice elevator 7 (S105 to S108).

When the hulling and sorting work is coming to an 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 remaining rice processing operation is started (S109 to S111). That is, when the circulation/discharge switching valve 59 is switched to the circulation side, the remaining rice is circulated within the machine and returned to the hulling device 2 where it is husked, and after a predetermined period of time, the circulation/discharge switching valve 59 is switched to the discharge side again. The remaining rice is then discharged from the machine via the finished rice elevator 7 (remaining rice processing operation, S109 to S114).

During the circulation of the remaining rice in the machine and until a predetermined period of time has elapsed after the circulation/discharge switching valve 59 is switched to the discharge side, the air valve 51 is operated to direct air from the compressor 41 to the second connection hose 42b. Switching to the third supplying position, the mixed rice elevator 4 blows out air to dispose of the remaining rice. Thereafter, it is switched to the first position (a) where air is supplied to the first connection hose 42a, and the finished rice elevator 7 blows out air to dispose of the remaining rice (cleaning mode operation, S115 to S117). During this cleaning mode operation, continuous air jetting is switched to intermittent air jetting. Continuous jetting can promote the discharge of leftover rice at the bottom of the elevator, and intermittent jetting thereafter can effectively discharge small amounts of leftover rice. When the cleaning mode operation ends, the main motor 25 is turned off and the driving of each part of the apparatus is stopped (S118).

When the re-cleaning mode switch 69 is operated after completing the hulling and sorting work, the main motor 25 is turned on and after a predetermined period of idle operation in which all parts are driven, the compressor 41 is driven. Further, the air valve 51 is switched to the third position where air is supplied to the second connection hose 42b, and the mixed rice elevator 4 is made to blow out air to dispose of the remaining rice. position, and the finished rice elevator 7 blows out air to dispose of the remaining rice (re-cleaning mode operation, S119 to S121). When operating in the re-cleaning mode described above, care must be taken in handling the operating lever 55. That is, when the operating lever 55 is operated to return to the first operating position at the left end of the guide groove 56, the re-cleaning mode operation is restrained. When entering the initial setting mode for adjusting the gap between the hulling rolls 2b, 2b, re-cleaning mode operation can be avoided.

The relationship between the remaining rice processing operation in S111 and S112 in FIG. 18, the cleaning mode operation in S115 to S117, and the re-cleaning mode operation in S119 to S121 in FIG. 18 is shown in detail in FIG.

In FIG. 18, regarding the transition to the cleaning mode operation in S115 to S117, the mode may be configured to automatically transition to S115 after the remaining rice discharging operation in S114 for each hulling sorting operation, and the mode can be automatically shifted to S115 before the operation starts. The cleaning mode operation may be performed only when the cleaning mode switch 70 provided at 62 is manually operated. The digital display section 66 is configured to display a countdown of the remaining time of the cleaning mode operation to notify the operator.

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 depending on the rotational operation of the switch 68. Although the valve switch is shown in FIG. 19, it is a comparative representation for outputting a signal corresponding to the first position, second position, or third position from the control unit, and the valve switch 68 is manually rotated. The configuration is such that signals corresponding to these positions are automatically output to switch and control the air valve 51 without the need for a switch.

Although the air valve 51 is in the form of an electromagnetically operated directional control valve, it is also in the form of a switching valve operated by a mechanical spool, and this switching valve and a switching operation tool that replaces the valve switch 68 are mechanically interlocked and connected by wires, rods, etc. It's okay. In short, any configuration may be sufficient as long as the switching valve that can be switched to the first position, the second position, or the third position is interlocked by a switching operation means that is electrically or mechanically interlocked.

As described above, since the cleaning mode operation and the re-cleaning mode operation are provided, no residual rice is left at the bottom of the mixed rice elevator 4 or the finished rice elevator 7. By the way, the air blowing time is configured to be changeable, and depending on the grain variety to be hulled and sorted, for example, the air blowing time is set to a standard time for non-glutinous rice, but the air blowing time is lengthened for naked wheat. Since naked wheat has a significant amount of dust attached to it, it is possible to improve the removal of foreign substances by making it longer.
