By providing the re-sorting communication part 18a behind the , it is possible to simplify the transportation process of the unhulled rice and the unhulled rice separated by the unhulled rice separator 16 .

The receiving part 15 for distribution is provided below the mixed rice tank 5, and the mixed rice from the mixed rice tank 5 passes through a transfer gutter part 15a formed in a wide width, and from the back side of the multistage swing sorting plate 14 to each stage. It is supplied to the distribution gutter 14d for distribution. In order to separate long foreign objects D mixed in the mixed rice, the receiving part 15 shown in the see-through front view including the partial arrow view of FIG. , and a side discharge port 21 is formed facing the discharge end for discharging the long foreign matter D sideways. Between the discharge end of the receiving part perforated plate 20 and the side discharge port 21, there is a sorting part perforated plate 22 formed with a through hole 22a through which the mixed rice is leaked and supplied to the uppermost rocking sorting plate 14. prepare. The perforated hole 22a is formed over the entire width at least on the discharge end side of the receiving part perforated plate 20. As shown in FIG. Almost most of the mixed rice leaks from the receiving perforated plate 20 to the transfer gutter 15a and is transferred toward the distribution gutter 14d, and a transfer rack may be appropriately formed in the transfer gutter 15a. A leveling valve 23 for adjusting the flow rate is provided on the swinging side of the receiving portion 15 for distribution so that the amount of inflow from the distribution gutter 14d to the swinging sorting plates 14 of each stage can be made uniform. In addition, although the succeeding sorting section perforated plate 22 is a short section, it is inclined slightly upward toward the side discharge port 21 to delay the transfer of the long foreign matter D and allow the remaining mixed rice to leak down.

The receiving perforated plate 20 having the above-described configuration distributes and supplies the mixed rice received from the mixed rice tank 5 to the swinging sorting plates 14 by swinging and leaking down to the mixed rice flow-down plate 15a below. The long foreign matter D in the mixed rice remaining on the perforated plate 20 of the receiving part is moved to the end side by the rocking motion. 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 down and is supplied to the rocking sorting plate 14 on the uppermost stage. It is discharged from the discharge port 21 . Therefore, the simple configuration of the receiving part perforated plate 20 and the sorting part perforated plate 22 can sequentially discharge long foreign objects D such as straw scraps.

In this case, by arranging the sorting section perforated plate 22 at a position facing the rocking sorting plate 14 on the uppermost stage, the mixed rice can be supplied to the rocking sorting plate 14 without requiring a special guide member. can. In addition, the perforated plate 22 of the sorting section is inclined up to the side discharge port 21, so that the movement of the long foreign matter D is suppressed and the mixed rice can be reliably leaked.

A support portion 48 having a base plate 48a and a nozzle mounting surface 48b is mounted. The fourth air nozzle 46 raises the residual rice on the bottom of the finished rice elevator 7 to improve the efficiency of raking the bucket.

Here, the air hose to the third air nozzle 45 on the side of the mixed rice elevator 4 and the air hose to the fourth air nozzle 46 on the side of the finished rice elevator 7 are the air hose to the side of the mixed rice elevator 4 where the amount of residual rice and bran is relatively large. The diameter 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 air hose diameters different, so-called misassembly can be prevented.

The compressor 41 is installed on the front side of the hull sorter 1, and an air filter 50 and an air valve 51 are connected in series to the compressor 41 on a front cover 49 on the front side of the machine. A first connection hose 42a and a second connection hose 42b are connected by branching into two from an air valve 51 for switching air supply stoppage. 45 and the 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. As shown in FIG. Although the air valve 51 is one form of switching means, it is in the form of an electromagnetically operated directional control valve as will be described later.

The attachment of the air filter 50 to the airframe is arbitrary, but it can also be arranged on the left side of the operation section including the operation lever 55 and the like. Good maintainability. Further, by arranging the air filter 50 in the vicinity of the location where the power supply harnesses (not shown) of the aircraft are arranged, the power supply harnesses can be routed and the arrangement can be facilitated. When the air valve 51 is configured mechanically as described later, it is convenient that the height of the air filter 50 is lower than that of the air valve 51 .
A connection hose connecting the air filter 50 and the air valve 51 is arranged inside the detachable body cover. Maintainability and cleanability can be improved.

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

The circulation/discharge switching valve 59 has a discharge side that guides the sorted brown rice on the surface of the rocking 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. is configured to switch between If the amount of material to be sorted on the surface of the rocking sorting plate 14 decreases, rice grains will be mixed in the finished brown rice. While returning to 14, part of it can be returned to the hulling device 2 via the re-hulling path 12, and combined with the re-hulling process, the remaining rice can be stripped and sorted. As shown in FIG. 16, the circulation/discharge switching valve 59 is configured to be switched by a circulation/discharge switching motor M1. The operating lever 55 and the circulation/discharging switching valve 59 are interlocked by a circulation/discharging operating wire 60, and the operation of the operating lever 55 switches the rice shutter valve 57, the rocking switching pulley 61, and the circulation/discharging switching valve 59. It is interlocked so that it can be operated.

The gap between the hulling rolls 2b, 2b is adjusted by driving a roll gap adjusting motor M2.

An operation panel 61 is provided at the front central upper portion of the hull sorter. A power ON/OFF switch 63, an operation switch 64, a stop switch 65, and the like are provided on one of the left and right sides (the right side in the figure) of the operation panel 61. As shown in FIG. 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 in a front view, that is, on the left side in the figure, at a position near the guide groove 56 of the operation lever 55 . The air valve 51 has a function of switching the direction of air supply to the first connection hose 42a side or the second connection bosu 42b side as well as switching between supply and stop of air supply, and supplies air to the first connection hose 42a. A first position where air supply is stopped, a neutral second position where air supply is stopped, and a third position where air is supplied to the second connection hose 42b are switched to form an electromagnetically operated directional control valve. The valve switch 68 is configured to be rotated rightward or leftward from the central neutral position to switch to three positions. An electromagnetic solenoid (not shown) is excited to switch the valve 51 to the second position (B) when the switch 68 is in the neutral position, and to switch the valve 51 to the third position (C) when the switch 68 is turned to the left ( See Figure 17).

As described above, the air valve 51 can be switched by the operator's operation of the valve switch 68, so that the remaining rice can be appropriately disposed of according to the progress of the work. For example, when processing leftover rice in the mixed rice elevator 4, the valve switch 68 is rotated leftward from the second position (C) of 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 connection hose 42b, and the leftover rice in the lower part of the mixed rice elevator 4 can be treated. On the other hand, when the leftover rice in the finished rice elevator 7 is to be processed, the valve switch 68 is turned rightward from the neutral position (B) to switch the air valve 51 to the first position (C), whereby the first connecting hose 42a is turned on. Air can be jetted from the third air nozzle 45 and the fourth air nozzle 46 via the , and the leftover rice in the mixed rice transfer trough 35 and the leftover rice in the lower part of the finished rice elevator 7 can be treated.

A valve switch 68 as a switching operation means for the air valve 51 is rotated so as to supply the air nozzles 45 and 46 to the mixed rice elevator 4 to one of the left and right sides and the air nozzle 40 to the finished rice elevator 7 to the other left and right with the neutral position in the center. Since the air valve 51 is operated dynamically, the air valve 51 can be configured as the switching operation means while operating the operation panel 62, and the operation while operating the operation 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 body. A valve switch 68 is arranged between the operation panel 62 and the huller 2, that is, on the left side of the operation panel 62 in the figure, and the mixed rice elevator is moved by turning the valve switch 68 leftward from the neutral position. 4, the direction of the rotation operation is set so that air is blown to the finished rice elevator 7 by the rotation operation to the right from the neutral 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 used. In other words, when the air is jetted to the mixed rice elevator 4, the “circulation” lamp L2 is turned on, and when the air is jetted to the finished rice elevator 7, the “discharge” lamp L3 is turned on. You can check whether it is mode operation.

Further, the lighting device 76 may blink instead of the "circulation" lamp L2 or the "exhaust" lamp L3, or at the same time. Air ejection timing can be clarified, and air can be supplied at appropriate timing. The air supply to the mixed rice elevator 4 and the air supply to the finished rice elevator 7 may be separately notified. By making the flashing patterns of the lighting fixtures 76 different, for example, it is possible to distinguish them by the difference in the flashing period, and it is possible to determine which elevator the air is being supplied to, thereby improving the workability.

Next, based on FIG. 18, the air ejection control in the remaining rice processing process at the end of the hull 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 from the first operation position is moved to the second operation position, the paddy shutter valve 57 is opened and the paddy sorting operation is started (S103, S104).

The mixed rice of unhusked and 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-S108).

When the hulled rice sorting operation is nearing the end and the weight of the mixed rice tank 5 becomes less than a predetermined weight, the circulation/discharging switching valve 59 is switched to the circulation side, and the remaining rice processing operation is started (S109-S111). That is, when the circulation/discharge switching valve 59 is switched to the circulation side, the residual rice circulates in the machine and is returned to the rice huller 2 to be dehulled. After switching, the leftover rice is discharged out of the machine through the finished rice elevator 7 (remaining rice processing operation, S109 to S114).

During the circulation of the leftover rice in the machine and until a predetermined time elapses after the circulation/discharge switching valve 59 is switched to the discharge side, the air valve 51 is operated to direct the air from the compressor 41 to the second connection hose 42b. After switching to the third supply position, the mixed rice elevator 4 is caused to blow air to dispose of the remaining rice. After that, it is switched to the first position (a) where air is supplied to the first connection hose 42a, and the finished rice elevator 7 is caused to eject air to treat the remaining rice (cleaning mode operation, S115 to S117). During this cleaning mode operation, the continuous air ejection is switched to the intermittent air ejection. Continuous jetting can accelerate the discharge of the leftover rice at the bottom of the elevator, and then intermittent jetting can effectively discharge a small amount of leftover rice. Then, 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 finishing the hull sorting work, the main motor 25 is turned on, and the compressor 41 is driven after idle operation in which each part is driven for a predetermined time. Further, the air valve 51 is switched to the third position to supply air to the second connection hose 42b, and the mixed rice elevator 4 is caused to eject air to treat the remaining rice. position, and the finished rice elevator 7 is caused to blow air to treat the remaining rice (recleaning mode operation, S119 to S121). Care must be taken in handling the operating lever 55 during the recleaning mode operation. That is, when the operation lever 55 is returned to the first operation position at the left end of the guide groove 56, the recleaning mode operation is restrained. Re-cleaning mode operation can be avoided when entering an initialization mode for performing gap adjustment between the hulling rolls 2b, 2b.

FIG. 16 shows details of the relationship between the remaining rice processing operation of S111 and S112 of FIG. 18, the cleaning mode operation of S115-S117, and the re-cleaning mode operation of S119-S121.

In FIG. 18, regarding the transition to the cleaning mode operation of S115 to S117, it may be configured such that the mode is automatically shifted to S115 after the residual rice discharge operation of S114 for each hull sorting operation. The cleaning mode operation may be performed only when the cleaning mode switch 70 provided at 62 is manually operated. The digital display unit 66 is constructed so as to display the countdown of the remaining time of the cleaning mode operation so as to inform the operator.

During the cleaning mode operation or during 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 turning the switch 68 . In FIG. 19, the valve switch is indicated, but it is a comparative notation for outputting a signal corresponding to the first position, the second position or the third position from the control unit, and the valve switch 68 is manually rotated. A signal corresponding to these positions is automatically output to switch and control the air valve 51 without requiring a .

Although the air valve 51 is in the form of an electromagnetically operated directional control valve, it is in the form of a switching valve operated by a mechanical spool. may In short, it is sufficient that 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 electrically or mechanically interlocks.

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 variety to be hulled and sorted, for example, the standard time is set for non-glutinous rice, but the air ejection time is lengthened for bare barley. Since bare barley is markedly dusty, it is possible to improve the removal of contaminants by lengthening the barley.

The separated rice husks are discharged from the rice husk duct 3a by the wind selection unit 3, and the wind-selected grains (mixed rice of rice and brown rice) are stored in the mixed rice tank 5 by the mixed rice elevator 4, This mixed rice is supplied from the mixed rice tank 5 whose supply can be adjusted to the sorting starting end H side of the rocking sorting device 6 as shown in FIG. The brown rice is sorted by specific gravity on the raising side, and the sorted brown rice is partitioned by arranging a movable brown rice partition plate 8 on the sorting end side T in accordance with the sorting area A of this brown rice, and finished through a discharge path 9 leading to the finished rice elevator 7. Discharge as brown rice (Fig. 3).

On the other hand, for the unhulled rice sorted on the swinging down side of the swing sorting device 6, the sorted unhulled rice in the unhulled region B is recycled to the thrower 11 by arranging the movable paddy partition plate 10 according to the unhulled region B. The mixed rice that is returned to the huller 2 again through the hulling path 12 and sorted into the remaining mixed rice area C is circulated again to the rocking sorting device 6 through the re-sorting path 13 leading to the mixed rice elevator 4. supply. In this way, as the hulling work progresses, the brown rice is sorted and discharged from the brown rice area A by the finished rice elevator 5 as finished brown rice.

The swing sorting device 6 will be described in detail. As shown in the front view (a) and side view (b) of FIG. 4 and FIG. A mixed rice distribution unit consisting of a distribution receiving unit 15 that receives mixed rice and distributes and supplies it to each rocking sorting plate 14 is integrally configured, and the left side plate 14a that is the rocking side has a sorting of the rice area B. A paddy/unpolished rice separator 16 for guiding paddy to a re-hulling path 12 is provided.

The multistage rocking sorting plates 14 constituting the rocking sorting device 6 are each formed with a large number of sorting recesses 14c. By tilting and swinging left and right while receiving the mixed rice from the distribution receiving portion 15 with the portion raised, the grains are sorted by specific gravity with the front end portion of each portion being the sorting end side T. An unpolished rice region A of the unpolished rice layer is formed on the rocking side of the rocking sorting plate 14, a chaff region B of the chaff layer is formed on the rocking side, and a mixed rice region C of the mixed rice layer is formed on the intermediate portion.

A paddy guide port 17 for taking out the paddy of 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, and A box-shaped unhulled rice separator 16 is attached to the opposing position via a side plate 14a. The unhulled rice separator 16 receives the unhulled rice in the unhulled region B of each rocking sorting plate 14 through the unhulled rice guide port 17, where the unhulled rice is separated from the unhulled rice. It is configured to guide the unpolished rice to the re-sorting path 13.

In the unhulled rice separator 16, there are provided perforated plates 16a formed with a large number of perforated holes, which are mesh bodies through which the unhulled rice mixed with the hulls leaks. Below each perforated plate 16a, there is provided a brown rice guide plate 16b for receiving the brown rice that has been leaked and sorted. That is, the perforated plates 16a and the unpolished rice guide plates 16b are arranged alternately in the vertical direction.

On the unpolished rice discharge side of the unpolished rice guide plate 16b, an unpolished rice guide passage 18 through which the unpolished rice discharged from each unpolished rice guide plate 16b is collectively guided is provided. In addition, a paddy guide passage 19 is provided for collectively guiding the paddy that has not leaked through the perforated plate 16a of each stage, and the paddy guide passage 19 and the re-hulling path 12 are communicated.

The unpolished rice guide passage 18 of this embodiment is arranged on the side of the unpolished rice guide plate 16b, and the chaff guide passage 19 is arranged on the front side of the perforated plate 16a.

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

The unhulled rice in the unhulled region B flows into the perforated plate 16 a of the unhulled rice separator 16 through the unhulled grain guiding port 17 provided for each of the multi-stage swing sorting plates 14 . The unpolished rice mixed in is leaked from the perforated plate 16a, and the unhulled rice remaining on the perforated plate 16a flows into the unhulled rice guiding passage 19 while being prevented from flowing into the unpolished rice guiding passage 18 by the unhulled rice partitioning wall 16S, and is re-hulled. It falls on the road 12 and is guided. In addition, the unpolished rice that has leaked through the perforated plate 16a drops onto the unpolished rice guide plate 16b and is supplied, enters the unpolished rice guide passage 18 while being prevented from flowing into the unhulled rice guide passage 19 by the unpolished rice partition wall 16G, and drops to be re-sorted. You will be guided to Road 13. With this configuration, the unpolished rice mixed with the unhulled rice taken out from the unhulled region B can be sorted with high accuracy by sorting each stage without stagnation.

In this case, the unhulled rice separator 16 is provided along the outer side of the side plate 14a, and a long sorting process is formed by the long perforated plate 16a in the front-rear direction. The amount of unpolished rice returned to the rubbing device 2 is reduced, and the amount of unpolished rice that has been rubbed twice can be reduced. Further, the sorted unpolished rice can be rapidly re-sorted through the re-sorting path 13 .

In addition, each unpolished rice guide plate 16b is provided with an inclination angle for sending unpolished rice to the unpolished rice guide passage 18 side below the perforated plate 16a of the chaff guide port 17, so that the leaking sorted grains received from the perforated plate 16a are quickly displaced. It is possible to conduct efficient re-selection without stagnation. In addition, the perforated plate 16a is provided parallel to the rocking sorting plate 14, and like the rocking sorting plate, it is inclined forward and downward, so that the chaff can be smoothly discharged into the chaff guide passage 19.

In addition, a re-sorting communication portion 18a is connected to the lower end of the unpolished rice guide passage 18 so that the lower end of the rocking sorting plate 14 is inclined, and the re-sorting communication portion 18a is communicated with the re-sorting passage 13, whereby the chaff guide passage 19 is formed. By providing the re-sorting communication part 18a behind the , it is possible to simplify the transportation process of the unhulled rice and the unhulled rice separated by the unhulled rice separator 16 .

The receiving part 15 for distribution is provided below the mixed rice tank 5, and the mixed rice from the mixed rice tank 5 passes through a transfer gutter part 15a formed in a wide width, and from the back side of the multistage swing sorting plate 14 to each stage. It is supplied to the distribution gutter 14d for distribution. In order to separate long foreign objects D mixed in the mixed rice, the receiving part 15 shown in the see-through front view including the partial arrow view of FIG. , and a side discharge port 21 is formed facing the discharge end for discharging the long foreign matter D sideways. Between the discharge end of the receiving part perforated plate 20 and the side discharge port 21, there is a sorting part perforated plate 22 formed with a through hole 22a through which the mixed rice is leaked and supplied to the uppermost rocking sorting plate 14. prepare. The perforated hole 22a is formed over the entire width at least on the discharge end side of the receiving part perforated plate 20. As shown in FIG. Almost most of the mixed rice leaks from the receiving perforated plate 20 to the transfer gutter 15a and is transferred toward the distribution gutter 14d, and a transfer rack may be appropriately formed in the transfer gutter 15a. A leveling valve 23 for adjusting the flow rate is provided on the swinging side of the receiving portion 15 for distribution so that the amount of inflow from the distribution gutter 14d to the swinging sorting plates 14 of each stage can be made uniform. In addition, although the succeeding sorting section perforated plate 22 is a short section, it is inclined slightly upward toward the side discharge port 21 to delay the transfer of the long foreign matter D and allow the remaining mixed rice to leak down.

The receiving perforated plate 20 having the above-described configuration distributes and supplies the mixed rice received from the mixed rice tank 5 to the swinging sorting plates 14 by swinging and leaking down to the mixed rice flow-down plate 15a below. The long foreign matter D in the mixed rice remaining on the perforated plate 20 of the receiving part is moved to the end side by the rocking motion. 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 down and is supplied to the rocking sorting plate 14 on the uppermost stage. It is discharged from the discharge port 21 . Therefore, the simple configuration of the receiving part perforated plate 20 and the sorting part perforated plate 22 can sequentially discharge long foreign objects D such as straw scraps.

In this case, by arranging the sorting section perforated plate 22 at a position facing the rocking sorting plate 14 on the uppermost stage, the mixed rice can be supplied to the rocking sorting plate 14 without requiring a special guide member. can. In addition, the perforated plate 22 of the sorting section is inclined up to the side discharge port 21, so that the movement of the long foreign matter D is suppressed and the mixed rice can be reliably leaked.

A foreign object receiver 21D for receiving a long foreign object D from the side discharge port 21 swings at a position directly below the side discharge port 21 as shown in the exploded perspective view (a) and the main part side view (b) of FIG. A receiving plate portion 24b is provided so as to be openable in an opening formed in an overhanging portion 24a of an exterior cover 24 covering the rear side of the dynamic sorting plate 14. - 特許庁That is, the receiving plate portion 24b forms a part of the exterior cover 24. As shown in FIG.

The foreign object receiver 21D supports the receiving plate 24b with a hinge or the like so that it can be opened, thereby preventing foreign matter from entering from the outside when closed, and at the same time, the long length separated from the mixed rice received in the mixed rice distributing portion is provided. The foreign matter D is received from the side discharge port 21 and stored. By rotating the receiving plate portion 24b at a side position of the machine body to open the foreign matter D, the receiving plate portion 24b acts as an inclined guide and is dropped out of the machine. The stored foreign matter D can be stored in a lower storage member (not shown) without touching it.

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

A top cover 71 is provided on the front side of the distribution receiving portion 15 in the upper portion of the rocking sorting device 6 to cover the uppermost rocking sorting plate 14 from above. Further, a front cover 72 is provided so as to be continuous with the top cover 71 and cover the front surfaces of the multistage swing sorting plates 14 . These top cover 71 and front cover 72 are fastened and fixed to the machine frame of the rocking sorting device 6 . A transparent inspection cover 73 made of transparent resin is provided near the front side of the top cover 71 so as to be openable and closable around the fulcrum X on the rear side. On the lower surface of the upper surface cover 71 and closer to the rear, a middle portion of a dust collecting cylinder 74 for collecting dust from the finished rice of the finished rice elevator 7 is supported. That is, the dust collecting 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 selection section 3, and the finished rice discharged from the finished rice elevator 7 configured to suck and remove dust from the It is surrounded and supported by a top cover 71 and a cylindrical support frame 75 fixed to the inside of the top cover 71 by means of welding or the like so as to hang down. That is, a pair of front and rear wall members 75f and 75r and a bottom portion 75b are formed by bending a cylindrical support frame 75 made of sheet metal material and a top cover 71 to form a rectangular cylindrical body with left and right openings. 74 is inserted, and the intermediate portion thereof is supported by a cylindrical body support frame 75 .

The part side, that is, the sorting terminal side T is configured so that it can be irradiated from above the swing sorting plate 14 . That is, the illuminator 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 predetermined intervals within a straight tubular cover. The support stay 77 is fixed, and the seat surface of the lighting fixture 76 is fixed and attached to the tip portion bent at an acute angle. The irradiation direction is obliquely downward from the mounting position above the rocking sorting plate 14 by bending at an acute angle so that the sorting end side T of the rocking sorting plate 14 can be irradiated as described above.

Since the illumination of the illumination device 76 configured as described above is directed toward the discharge tip of the swing sorting plate 14, when the swing sorting plate 14 surface is viewed from above the swing sorting plate 14, the swinging The positions of the finishing partition plate 8 and the paddy partition plate 10 with respect to the sorting plate 14 can be clearly confirmed, improving visibility.

The lighting device 76 is long in the swinging direction of the swing sorting plate 14, that is, in the left-right direction, as described above. The longitudinal length of the illumination device 76 and the arrangement configuration of the related multiple LEDs are set so that the sorting end side T (discharging tip) of the rocking sorting plate 14 in the unpolished rice region A can be illuminated beyond the .

Further, since the lighting fixture 76 is provided on the wall member 75f formed on the upper surface cover 71 to support the cylindrical dust collecting body 74, it is mounted using the members necessary for installing the cylindrical dust collecting body 74. A good installation can be achieved by If the wall member 75f can be substituted for the wall member 75f by making a part of the cylindrical dust collecting body 74 from a sheet metal, the dust collecting cylindrical body 74 can be supported directly.

The relationship between the illuminator 76 and the rotation fulcrum X of the transparent inspection cover 73 attached to the top cover 71 will be described. As shown in FIG. 8, the transparent inspection cover 73 has a V-shaped cross section. 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 this support shaft 78 as a rotation fulcrum X. . A distance is provided from the rotation fulcrum X, that is, the boss portion 73a to the rear end of the transparent inspection cover 73 so that no gap is formed between the opening of the top cover 71 and the rear end side of the transparent inspection cover 73. there is The lighting device 76 and the pivot point X are close to each other, but the position of the lighting device 76 is on the rear side of the pivot point X, i. It is located on the far side of the bottom of the Therefore, even when the transparent inspection cover 73 is opened to inspect the interior, the illumination from the lighting device 76 does 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 a dust suction wind, so that the dust can be discharged from the rice husk duct 3a. The suction blower 3b of the rice husk duct 3a is provided with a fan 3c, and the suction areas of the main air passage of the wind selection section 3 and the suction air passage of the dust collection tube 74 are set at the suction port of the suction blower 3b. By increasing the area of the suction air passage on the side of the dust suction tube 74 after finishing the hull sorting work, a large amount of dust and leftover rice remaining after the hulling work is sucked by the suction blower 3b. and can be discharged from the rice husk duct 3a.

In FIG. 9, the configuration of the end portion of the dust collecting tube 74 is shown. A dust suction port 7d is formed 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 body 74 is detachably and retainably attached to the dust suction port 7d. are doing. When the end portion of the dust collecting tube 74 is removed, the rectangular opening 74c of the insertion tube 74b can be used as a cleaning port, and combined with the flexible tube structure, can be used to clean each part of the machine body and the surroundings of the machine body.

The transmission configuration of each part of the hull sorter by the motor 25 (Fig. 10) transmits the roll shaft 2c that supports the hull rolls 2b, 2b of the hulling device 2 via the first belt 26 from the motor 25. From the roll shaft 2c through the second belt 27, the swing shaft 28a of the sludged rice transfer shelf 28, the interlocking shaft 4a of the mixed rice elevator 4, the second spiral shaft 29, the swing sorting device 6 interlocking shaft, etc. are transmitted. From the elevator 4 interlocking shaft 4a through the third belt 30, the mixed rice elevator 4 interlocking shaft 4a and the mixed rice spiral 31 shaft are transmitted, and from the second spiral 29 shaft through the fourth belt 32, the suction blower The fan 3c shaft of 3b is transmitted, the oscillating crankshaft 6b is transmitted from the oscillating sorting device 6 interlocking shaft 6a through the fifth belt 33, and the finished rice elevator 7 shaft is transmitted through the sixth belt 34. form.

Note that the second belt 27 may be divided into two. That is, the roll shaft 2c, the swinging shaft 28a of the sludged rice transfer shelf 28, and the interlocking shaft 4a of the mixed rice elevator 4 are interlocked by the divided first V-belt 27A, and the interlocking shaft 4a of the mixed rice elevator 4 and the second screw 29 The shaft 29a, the oscillating sorting device 6 interlocking shaft 6b, and the finished rice elevator 7 interlocking shaft 7B are interlocked by a second divided belt 27B in the form of a hexagonal belt (Fig. 11). With this configuration, when a load such as clogging is applied to the huller 2, the first divided belt 27A slips and the second divided belt 27B is less likely to be loaded.

Next, based on FIGS. 12 and 13, the configuration for transporting mixed rice and the configuration for processing leftover rice will be described. The mixed rice spiral 31 is arranged in a mixed rice transfer trough 35, and receives the sludged rice flowing down from the sludged rice transfer shelf 28 of the hulling device 2 and the mixed rice in the re-sorting path 13, and receives the mixed rice. It is configured to be transferred to the elevator 4 . A plurality of buckets 4b, 4b, . is set up 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 connection part 35a of the mixed rice transfer gutter 35 is fixed on the grain scooping side (lowering process side) of the buckets 4b, 4b, . Mixed rice is configured to flow down and be guided to the lower part of the elevator 4 from the communication opening to the lower end wall of the mixed rice elevator 4 .

An on-off valve 36 is provided along the conveying direction of the mixed rice transfer trough 35 so that the bottom of the mixed rice transfer trough 35 can be opened and closed, and the leftover rice accumulated at the bottom of the transfer trough 35 can be discharged. Below the on-off valve 36, a leftover rice receiving box 37 is provided as a leftover rice receiving portion for receiving the discharged leftover rice.

The mixed rice elevator 4 is erected behind the machine body of the rice huller 1 with the second belt 27 therebetween, i.e., behind the rear cover 38 covering the rear of the machine body at an appropriate distance. The end side of the transfer trough, which is the connecting portion 35a of the mixed rice transfer trough 35, is also located behind the machine body, and the bottom opening provided in the mixed rice transfer trough 35 and the corresponding on-off valve 36 is a structure arranged in the section inside the fuselage.

A first air nozzle 40 is arranged below 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 connecting the mixed rice transfer trough 35. It is set diagonally downward toward the bottom of 4. Compressed air is supplied to the first air nozzle 40 through a connection hose 42 from a compressor 41 installed in front of the hull sorter 1 .

As described above, since the first air nozzle 40 is provided, the remaining rice on the bottom of the mixed rice elevator 4 is sprung up by the air jet from the nozzle after the end of the hull sorting operation, and scooped by the buckets 4b, 4b, . . . Efficient lifting.

In addition, a second air nozzle 43 is provided at the connecting portion 35a of the mixed rice transfer gutter 35 and the mixed rice elevator 4. As shown in FIG. The second air nozzle 43 is attached to the upper wall portion of the mixed rice transfer gutter 35, and is provided so that the direction of jet air from the nozzle is directed toward the transfer direction opposite to the transfer direction (b) of the mixed rice spiral 31. As shown in FIG. The support 44 of the second air nozzle 43 is composed of a base plate 44a and an upward bulging portion 44c having a nozzle mounting surface 44b. It is fitted accordingly. The nozzle mounting surface 44b has an angle .alpha.

Since the second air nozzle 43 is provided in this way, after the hull sorting operation is completed, the on-off valve 36 is opened while the mixed rice spiral 31 and the mixed rice elevator 4 are driven, and air is jetted from the second air nozzle 43. As a result, the mixed rice about to be transferred to the transfer end side of the mixed rice transfer trough 35 can be collected in the residual rice receiving box 37 through the opening of the on-off valve 36 . Since the connecting portion 35a of the mixed rice transfer trough 35 does not have an on-off valve 36, the residual rice is moved to a location where the on-off valve 36 exists by blowing air in the direction opposite 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 at 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 bottom of the finished rice elevator 7 . The third air nozzle 45 facilitates discharging the remaining rice in the mixed rice transfer trough 35 downward from the on-off valve 36 . In addition, since it is mounted using the inspection cover 47 mounted on the front surface 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. The fourth air nozzle 46 raises the residual rice on the bottom of the finished rice elevator 7 to improve the efficiency of raking the bucket.

Here, the air hose to the third air nozzle 45 on the side of the mixed rice elevator 4 and the air hose to the fourth air nozzle 46 on the side of the finished rice elevator 7 are the air hose to the side of the mixed rice elevator 4 where the amount of residual rice and bran is relatively large. The diameter 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 air hose diameters different, so-called misassembly can be prevented.

The compressor 41 is installed on the front side of the hull sorter 1, and an air filter 50 and an air valve 51 are connected in series to the compressor 41 on a front cover 49 on the front side of the machine. A first connection hose 42a and a second connection hose 42b are connected by branching into two from an air valve 51 for switching air supply stoppage. 45 and the 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. As shown in FIG. Although the air valve 51 is one form of switching means, it is in the form of an electromagnetically operated directional control valve as will be described later.

The attachment of the air filter 50 to the airframe is arbitrary, but it can also be arranged on the left side of the operation section including the operation lever 55 and the like. Good maintainability. Further, by arranging the air filter 50 in the vicinity of the location where the power supply harnesses (not shown) of the aircraft are arranged, the power supply harnesses can be routed and the arrangement can be facilitated. When the air valve 51 is configured mechanically as described later, it is convenient that the height of the air filter 50 is lower than that of the air valve 51 .
A connection hose connecting the air filter 50 and the air valve 51 is arranged inside the detachable body cover. Maintainability and cleanability can be improved.

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

The circulation/discharge switching valve 59 has a discharge side that guides the sorted brown rice on the surface of the rocking 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. is configured to switch between If the amount of material to be sorted on the surface of the rocking sorting plate 14 decreases, rice grains will be mixed in the finished brown rice. While returning to 14, part of it can be returned to the hulling device 2 via the re-hulling path 12, and combined with the re-hulling process, the remaining rice can be stripped and sorted. As shown in FIG. 16, the circulation/discharge switching valve 59 is configured to be switched by a circulation/discharge switching motor M1. The operating lever 55 and the circulation/discharging switching valve 59 are interlocked by a circulation/discharging operating wire 60, and the operation of the operating lever 55 switches the rice shutter valve 57, the rocking switching pulley 61, and the circulation/discharging switching valve 59. It is interlocked so that it can be operated.

The gap between the hulling rolls 2b, 2b is adjusted by driving a roll gap adjusting motor M2.

An operation panel 61 is provided at the front central upper portion of the hull sorter. A power ON/OFF switch 63, an operation switch 64, a stop switch 65, and the like are provided on one of the left and right sides (the right side in the figure) of the operation panel 61. As shown in FIG. 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 in a front view, that is, on the left side in the figure, at a position near the guide groove 56 of the operation lever 55 . The air valve 51 has a function of switching the direction of air supply to the first connection hose 42a side or the second connection bosu 42b side as well as switching between supply and stop of air supply, and supplies air to the first connection hose 42a. A first position where air supply is stopped, a neutral second position where air supply is stopped, and a third position where air is supplied to the second connection hose 42b are switched to form an electromagnetically operated directional control valve. The valve switch 68 is configured to be rotated rightward or leftward from the central neutral position to switch to three positions. An electromagnetic solenoid (not shown) is excited to switch the valve 51 to the second position (B) when the switch 68 is in the neutral position, and to switch the valve 51 to the third position (C) when the switch 68 is turned to the left ( See Figure 17).

As described above, the air valve 51 can be switched by the operator's operation of the valve switch 68, so that the remaining rice can be appropriately disposed of according to the progress of the work. For example, when processing leftover rice in the mixed rice elevator 4, the valve switch 68 is rotated leftward from the second position (C) of 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 connection hose 42b, and the leftover rice in the lower part of the mixed rice elevator 4 can be treated. On the other hand, when the leftover rice in the finished rice elevator 7 is to be processed, the valve switch 68 is turned rightward from the neutral position (B) to switch the air valve 51 to the first position (C), whereby the first connecting hose 42a is turned on. Air can be jetted from the third air nozzle 45 and the fourth air nozzle 46 via the , and the leftover rice in the mixed rice transfer trough 35 and the leftover rice in the lower part of the finished rice elevator 7 can be treated.

A valve switch 68 as a switching operation means for the air valve 51 is rotated so as to supply the air nozzles 45 and 46 to the mixed rice elevator 4 to one of the left and right sides and the air nozzle 40 to the finished rice elevator 7 to the other left and right with the neutral position in the center. Since the air valve 51 is operated dynamically, the air valve 51 can be configured as the switching operation means while operating the operation panel 62, and the operation while operating the operation 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 body. A valve switch 68 is arranged between the operation panel 62 and the huller 2, that is, on the left side of the operation panel 62 in the figure, and the mixed rice elevator is moved by turning the valve switch 68 leftward from the neutral position. 4, the direction of the rotation operation is set so that air is blown to the finished rice elevator 7 by the rotation operation to the right from the neutral 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 used. In other words, when the air is jetted to the mixed rice elevator 4, the “circulation” lamp L2 is turned on, and when the air is jetted to the finished rice elevator 7, the “discharge” lamp L3 is turned on. You can check whether it is mode operation.

Further, the lighting device 76 may blink instead of the "circulation" lamp L2 or the "exhaust" lamp L3, or at the same time. Air ejection timing can be clarified, and air can be supplied at appropriate timing. The air supply to the mixed rice elevator 4 and the air supply to the finished rice elevator 7 may be separately notified. By making the flashing patterns of the lighting fixtures 76 different, for example, it is possible to distinguish them by the difference in the flashing period, and it is possible to determine which elevator the air is being supplied to, thereby improving the workability.

Next, based on FIG. 18, the air ejection control in the remaining rice processing process at the end of the hull 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 from the first operation position is moved to the second operation position, the paddy shutter valve 57 is opened and the paddy sorting operation is started (S103, S104).

The mixed rice of unhusked and 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-S108).

When the hulled rice sorting operation is nearing the end and the weight of the mixed rice tank 5 becomes less than a predetermined weight, the circulation/discharging switching valve 59 is switched to the circulation side, and the remaining rice processing operation is started (S109-S111). That is, when the circulation/discharge switching valve 59 is switched to the circulation side, the residual rice circulates in the machine and is returned to the rice huller 2 to be dehulled. After switching, the leftover rice is discharged out of the machine through the finished rice elevator 7 (remaining rice processing operation, S109 to S114).

During the circulation of the leftover rice in the machine and until a predetermined time elapses after the circulation/discharge switching valve 59 is switched to the discharge side, the air valve 51 is operated to direct the air from the compressor 41 to the second connection hose 42b. After switching to the third supply position, the mixed rice elevator 4 is caused to blow air to dispose of the remaining rice. After that, it is switched to the first position (a) where air is supplied to the first connection hose 42a, and the finished rice elevator 7 is caused to eject air to treat the remaining rice (cleaning mode operation, S115 to S117). During this cleaning mode operation, the continuous air ejection is switched to the intermittent air ejection. Continuous jetting can accelerate the discharge of the leftover rice at the bottom of the elevator, and then intermittent jetting can effectively discharge a small amount of leftover rice. Then, 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 finishing the hull sorting work, the main motor 25 is turned on, and the compressor 41 is driven after idle operation in which each part is driven for a predetermined time. Further, the air valve 51 is switched to the third position to supply air to the second connection hose 42b, and the mixed rice elevator 4 is caused to eject air to treat the remaining rice. position, and the finished rice elevator 7 is caused to blow air to treat the remaining rice (recleaning mode operation, S119 to S121). Care must be taken in handling the operating lever 55 during the recleaning mode operation. That is, when the operation lever 55 is returned to the first operation position at the left end of the guide groove 56, the recleaning mode operation is restrained. Re-cleaning mode operation can be avoided when entering an initialization mode for performing gap adjustment between the hulling rolls 2b, 2b.

FIG. 16 shows details of the relationship between the remaining rice processing operation of S111 and S112 of FIG. 18, the cleaning mode operation of S115-S117, and the re-cleaning mode operation of S119-S121.

In FIG. 18, regarding the transition to the cleaning mode operation of S115 to S117, it may be configured such that the mode is automatically shifted to S115 after the residual rice discharge operation of S114 for each hull sorting operation. The cleaning mode operation may be performed only when the cleaning mode switch 70 provided at 62 is manually operated. The digital display unit 66 is constructed so as to display the countdown of the remaining time of the cleaning mode operation so as to inform the operator.

During the cleaning mode operation or during 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 turning the switch 68 . In FIG. 19, the valve switch is indicated, but it is a comparative notation for outputting a signal corresponding to the first position, the second position or the third position from the control unit, and the valve switch 68 is manually rotated. A signal corresponding to these positions is automatically output to switch and control the air valve 51 without requiring a .

Although the air valve 51 is in the form of an electromagnetically operated directional control valve, it is in the form of a switching valve operated by a mechanical spool. may In short, it is sufficient that 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 electrically or mechanically interlocks.

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 variety to be hulled and sorted, for example, the standard time is set for non-glutinous rice, but the air ejection time is lengthened for bare barley. Since bare barley is markedly dusty, it is possible to improve the removal of contaminants by lengthening the barley.
