And mixed rice are sorted with drift distribution.

  Grains such as brown rice sorted by the swing sorting plate 18b are partitioned by the cocoon partition plate 18c and the brown rice partition plate 18d and discharged from the swing sorting plate 18b. At this time, when the distribution distribution of the grains on the rocking sorting plate 18b is unstable, the switching valve 22 causes the mixed rice flow path 20 and the brown rice flow path 21 to communicate with each other so that the mixed rice and brown rice flows. Is allowed to flow again into the catcher 15, but when the distribution of grain drift on the rocking sorting plate 18b is stabilized, the mixed rice flow path 20 and the brown rice flow path 21 are blocked. Can be switched.

  As a result, the mixed rice drops in the mixed rice flow path 20 and is conveyed again to the sorting unit 18 through the mixed rice receiver 15, and the brown rice is spirally held on the brown rice discharge basket 24 from the brown rice flow path 21. The rice is harvested by the brown rice cerealing machine 6 through a diffusion conveyor 25 that conveys the brown rice by rotating the screw, and is taken out from the finished rice outlet 9 to the outside. The soot is returned from the soot channel 19 via the return soot inlet portion 16a, and below the return soot inlet portion 16a, and is returned to the soot-reducing slot 16b that flows into the return soot outlet portion 16b communicated with the return soot inlet portion 16a. 16 is returned to the hulling portion 11 and hulled again.

  Next, a specific configuration of the remaining rice processing control apparatus that is a feature of the present invention will be described. FIG. 8 is a schematic diagram of the internal structure of the swing sorting type hulling device showing the installation position of the detector, and FIGS. 9 to 10 are block diagrams of the remaining rice processing control mechanism.

  As shown in FIG. 8, it is detected whether mixed rice is present in the mixed rice tank 4 and on the swing sorting plate 18b at the bottom of the mixed rice tank 4 and the upper portion of the swing sorting plate 18b, for example, a laser. Detectors 41 and 42 such as a type photoelectric sensor and an ultrasonic sensor are attached. As shown in FIG. 9, the detectors 41 and 42 are connected to a controller 43, and the controller 43 is connected to the solenoid valves of the air nozzles 34, 35, 36, 37, and 38. 42, the controller 43, and the solenoid valves of the air nozzles 34, 35, 36, 37, and 38 constitute a remaining rice processing control device 44.

  Here, when the mixed rice or brown rice remaining on the mixed rice transport rice bran 32 or the brown rice discharge rice bran 24 in the processing step is removed at the end or interruption of the preparation work by the swing sorting type rice huller 1 The detector 41 or the detector 42 or both detectors 41 and 42 detects whether or not the mixed rice remains on the bottom of the mixed rice tank 4 or the rocking sorting plate 18b or both. Next, based on the detection information, if the mixed rice remains on the bottom of the mixed rice tank 4 or the rocking sorting plate 18b or both, the controller 43 continues the preparation operation as it is, and the mixed rice When the mixed rice does not remain on the bottom of the tank 4 or on the swing sorting plate 18b or both, the operation of the swing sorting type rice huller 1 such as the mixed rice conveyor 31 is continued and the mixing is first performed. The solenoid valve (not shown) of the air nozzle 34 on the upper side of the rice conveyor 31 is opened, air is jetted from the air nozzle 34 toward the mixed rice cerealing machine 3 side, and the air stays on the mixed rice conveyor 31 or the mixed rice conveyance basket 32. The mixed rice to be fed is pressure-fed on the mixed rice transporter 32 to the mixed rice masher 3 side. In addition, the air injection from the air nozzle 34 may stop the air injection by closing the solenoid valve after a predetermined time injection (for example, continuous or fixed intervals) of about 10 seconds to 30 seconds, Air injection can be continued until the remaining rice treatment is completed.

  Next, the controller 43 opens a solenoid valve (not shown) of an air nozzle 35 that is provided at a connection location between the mixed rice conveyor 31 and the mixed rice cerealing machine 3, and air is supplied from the air nozzle 35 into the mixed rice cerealing machine 3. And the mixed rice staying in the vicinity of the terminal portions on the mixed rice conveyor 31 and the mixed rice conveying basket 32 on the lower side is dropped into the mixed rice masher 3. Here, the air injection from the air nozzle 35 may be stopped for example by closing the solenoid valve after a fixed time injection of about 10 seconds to 30 seconds (continuous or a fixed interval may be provided), Air injection can be continued until the remaining rice treatment is completed.

  Furthermore, the controller 43 opens a solenoid valve (not shown) of the air nozzle 36 that is provided in the vicinity of the bottom of the mixed rice cerealing machine 3 in the same way as during normal preparation work, and from the air nozzle 36 toward the bottom of the mixed rice cerealing machine 3. Air is injected, and the mixed rice staying at the bottom of the mixed rice cerealing machine 3 is blown up by this blast and is placed in a plurality of buckets 3a that circulate in the mixed rice cerealing machine 3. It is transferred into the mixed rice tank 4 and sorted by the swing sorting unit 18. The air injection from the air nozzle 36 may be performed by closing the solenoid valve after a fixed time injection (for example, continuous or fixed intervals) of about 10 seconds to 30 seconds to stop the air injection. Air injection can be continued until the rice treatment is completed.

  Next, the controller 43 opens a solenoid valve (not shown) of the air nozzle 37 that is located on the upper side of the diffusion conveyor 23 and in the vicinity of the brown rice masher 6, and air flows from the air nozzle 37 toward the brown rice masher 6. The brown rice staying on the diffusion conveyor 23 and the brown rice discharge basket 24 at the time of the above-described residual rice treatment is also fed into the brown rice cerealing machine 6 on the brown rice discharge basket 22. Also at this time, the air injection from the air nozzle 37 may be stopped by closing the electromagnetic valve after a fixed time injection (for example, continuous or fixed intervals) of about 10 seconds to 30 seconds, for example. However, the air injection can be continued until the remaining rice treatment is completed.

  Next, the controller 43 opens a solenoid valve (not shown) of the air nozzle 38 in the vicinity of the bottom of the brown rice cerealing machine 6 and injects air from the air nozzle 38 toward the bottom of the brown rice cerealing machine 6 (for example, 10 seconds to 30 seconds). Sprayed for a certain period of time for about a second), and the blown rice blows up the brown rice staying at the bottom of the brown rice cerealing machine 6 and crawls it into a plurality of buckets 6a that orbit around the brown rice cerealing machine 6. Later it is discharged out of the machine. When the remaining rice processing is completed, the controller 43 closes the solenoid valve of the air nozzle 38 (or closes the solenoid valves if the solenoid valves of the air nozzles 34, 35, 36, and 37 remain open), and the next preparation. The operation of the swing sorting type hulling device 1 is continued in preparation for the work or the operation of the swing sorting type hulling device 1 is stopped.

  By such a configuration of the remaining rice processing control mechanism, the mixed rice conveyor 31 and the mixed rice conveyance basket 32 and the diffusion conveyor 23 and the brown rice discharge basket 22 are displayed when the preparation operation by the swing sorting type rice huller 1 is completed or interrupted. Grain such as mixed rice or brown rice staying in the rice is fed from the air nozzle 34 further on the upper side 31a of the mixed rice conveying basket 32, which is the upper side of the processing step in the swing sorting type rice huller 1, The air nozzles 35 and 36 on the lower side 31b of the rice bran 32, and then the brown rice discharge rice cake 24 on the lower side of the processing step, the air nozzle 37 on the upper side and the air nozzle 38 on the lower side of the brown rice discharge rice cake 24 Since the solenoid valve is opened and air is blown in order, the residual grains are efficiently pumped from the upper side to the lower side of the processing process, and the residual grains can be removed reliably and automatically.The air is preferably injected at a pressure of, for example, 0.5 MPa, but a pressure, an injection time, and an injection interval can be appropriately set depending on the type of grain and the state of residual grains.

  Further, the remaining rice processing control device 44 'can be configured as follows. As shown in FIG. 10, in addition to the above-described detectors 41 and 42, a detector 45 such as a laser-type photoelectric sensor or an ultrasonic sensor, for example, is attached in the vicinity of the bottom in the hopper 2; Connected to the controller 43.

  Here, the remaining rice processing control mechanism when the remaining amount of the koji in the koji hopper 2 is reduced and the preparation operation is nearing the end will be described. First, the detector 45 detects whether or not the soot in the soot hopper 2 has become below a certain remaining amount. Next, the controller 43 continues the preparation work when the soot contained in the soot hopper 2 is not below a certain remaining amount based on this detection information, and the soot contained in the soot hopper 2 is below a certain remaining amount. In this case, the drive speed of each drive unit in the swing sorting type rice huller 1 such as the mixed rice conveyor 31, the mixed rice cerealing machine 3, the diffusion conveyor 23, and the brown rice cerealing machine 6 is made higher than usual. Set. Note that the drive speed of each drive unit that is higher than normal is set as appropriate.

  Next, the controller 43 is based on the information that the mixed rice does not remain on the bottom of the mixed rice tank 4 by the detectors 41 and 42, the rocking sorting plate 18b or both when the preparation work is completed. In the same manner as described above, the electromagnetic valves are opened in the order of the air nozzle 34, the air nozzles 35, 36, and then the air nozzles 37, 38 to blow air, and the remaining rice processing is performed.

  When the remaining rice processing is completed, the controller 43 returns the drive speed of each drive unit in the swing sorting type hulling device 1 to normal and closes the solenoid valve of the air nozzle 38 (air nozzles 34, 35, 36, 37). If the solenoid valves are still open, the solenoid valves are closed), and the operation of the swing sorting type hulling device 1 is continued or the operation of the swing sorting type hulling device 1 is stopped for the next preparation work. Let

  With this configuration of the remaining rice processing control mechanism, the drive speed of each drive unit in the swing sorting type hulling device 1 is driven at a speed higher than usual immediately before the preparation work is completed. Thus, the time until the remaining rice treatment that is started automatically and the time required to finish the remaining rice treatment are shortened, and workability is improved.

  Furthermore, you may comprise the remaining rice processing control apparatus 44 '' as follows. FIG. 11 is a block diagram of the remaining rice processing control mechanism in which a detector is provided in the vicinity of the straw supply shutter, and FIG. 12 is a schematic side view of the vicinity of the straw supply shutter S. At this time, as shown in FIG. 11, in addition to the detectors 41 and 42, a detector 46 is provided that detects the opening and closing of the hull supply shutter S that is above the hull portion 11 and below the hail hopper 2. In this case, as shown in FIG. 12, for example, limit switches 46a and 46b are used for the detector 46 on the kite supply shutter S and near the bottom of the kite hopper 2. The detector 46 may use an infrared sensor or the like on the wall surface between the hopper hopper 2 side and the pallet portion 11 side with the heel supply shutter S interposed therebetween, and the type and mounting position of the sensor are not limited.

  Here, for example, in the case where the supply of rice cake etc. from the rice hopper 2 to the rice hull portion 11 is temporarily stopped due to the situation in the processing process during the preparation work, the limit is set when the rice cake supply shutter S is closed by operating the lever 23b or the like. The detector 46 detects that the bag supply shutter S is closed by contact of the switches 46a, 46b and the like.

  Next, the controller 43 detects, based on the information of the detector 46, that the straw supply shutter S is closed and that no mixed rice remains on the bottom of the mixed rice tank 4 or on the swing sorting plate 18b or both. Based on the information of the detector 41 or the detector 42 or both detectors 41 and 42, the electromagnetic valve is opened in the order of the air nozzle 34, the air nozzles 35 and 36, and then the air nozzles 37 and 38 in the same manner as described above to blow air, Rice processing is done. When the remaining rice processing is completed, the controller 43 closes the solenoid valve of the air nozzle 38 (or closes the solenoid valves if the solenoid valves of the air nozzles 34, 35, 36, and 37 remain open), and swings and sorts. The operation of the type hulling device 1 is continued.

  With such a configuration of the remaining rice processing control mechanism, when the supply of rice cake etc. from the rice cake hopper 2 to the rice huller 11 is temporarily stopped, the lever 23b is operated in conjunction with the sliding position of the rice cake supply shutter S. In the state where the hulling process is not performed, the remaining rice processing in the processing process can be automatically performed, and the remaining rice processing operation is not required, and the workability is improved.
