The hull sorter according to the embodiment of the present invention will be described below.
On the left and right sides of the machine body, a rice hopper 1 for containing rice cake, an open / close shutter 2, a rice hull roll 3 for hulling, a transfer shelf 5 for transferring a mixed rice of rice hull and brown rice hulled by the rice hull roll 3, A main motor 21 is provided.

  In the left and right central part of the machine body, the wind selection unit 6 for wind-selecting the mixed rice transferred by the transfer shelf 5, the suction fan 7 for rice husk, the mixed rice helix 8 for transferring the mixed rice, and the mixing for cerealing the mixed rice A rice elevator 9 is provided. On the left and right sides of the machine, the mixed rice tank 10 that stores the mixed rice cerealed by the elevator 9 for mixed rice, the transfer rice pad 11 that transfers the mixed rice from the mixed rice tank 10, and the mixed rice is separated into rice and brown rice. A swing sorting plate 12 is provided. On the grain discharge side of the swing sorting plate 12, a straw partition plate 13 for partitioning the straw layer sorted by the swing sorting plate 12 and a brown rice partition plate 14 for partitioning the brown rice layer are provided. Below the grain discharge side of the swing sorting plate 12, the brown rice passage 19 through which the brown rice partitioned by the brown rice partition plate 14 passes, and the mixed rice that passes between the brown rice partition plate 14 and the straw partition plate 13 pass through. A rice passage 17 and a straw passage 15 through which the straw partitioned by the straw partition plate 13 passes are provided. The rice cake that has passed through the rice bran passage 15 is returned to the rice bran hopper 1 by a slot 16, the mixed rice that has passed through the mixed rice passage 17 is supplied to the mixed rice helix 8, and the brown rice that has passed through the brown rice passage 19 is supplied to the brown rice elevator 20. Is done.

Reference numeral 18 denotes a circulation / discharge switching valve which switches between supplying brown rice divided by the brown rice partition plate 14 to the brown rice passage 19 side (external discharge) or supplying the mixed rice passage 17 side (internal circulation).
As shown in FIG. 1, the hull sorter has a configuration in which the exterior is covered with an exterior cover although not indicated by reference numerals, and an operation panel 26 is provided at the left and right center of the machine body, and an operation lever 22 is provided above the operation panel 26. ing.

  As shown in FIG. 6, the operation panel 26 is provided with an operation switch 35 for starting operation and a stop switch 40 for stopping operation. A control unit 36 is built in the operation panel 26.

  As shown in FIG. 5, the operation lever 23 is configured to be operable in the left-right direction along the operation guide guide 41, and is operated at either the first position 37 as the initial position or the second position 38 as the hull sorting position. Thus, the operation position of the operation lever 23 is detected by the operation lever first position detection sensor 32 and the operation lever second position detection sensor 33, respectively.

  As shown in FIG. 3, the operation lever 23 is mechanically connected to the opening / closing shutter 2 and is connected to the swing on / off clutch 24 of the swing sorting plate 12 by a wire 28. The opening / closing shutter 2 is connected to the mixed rice tank 10 that moves up and down according to the amount of grain accommodated by a link mechanism 27. As a result, the amount of mixed rice in the mixed rice tank 10 is increased, and the opening / closing shutter 2 is closed as the mixed rice tank 10 is lowered, so that the amount of rice straw supplied to the hulling roll 3 is reduced. Further, the amount of mixed rice in the mixed rice tank 10 decreases and the opening / closing shutter 2 is opened as the mixed rice tank 10 is raised, so that the amount of rice straw supplied to the hulling roll 3 is increased.

  The mixed rice tank first sensor 30 detects that the mixed rice tank 10 is lowered by a predetermined amount or more, that is, the amount of mixed rice accommodated in the mixed rice tank 10 is not less than the predetermined amount. Then, the mixed rice tank second sensor 31 detects that the mixed rice tank 10 rises below the set amount, that is, the mixed rice amount stored in the mixed rice tank 10 falls below the set amount.

  The circulation / discharge switching valve 18 is switched by the circulation / discharge switching motor 25 between the internal circulation side and the external discharge side. The circulation / discharge switching valve 18 is automatically switched by the control unit 36, but can be manually switched by the operator using the circulation / discharge switching switch 34.

Next, the hull sorting operation will be described with reference to FIGS.
When the power switch is turned on and the operation switch 35 is operated, the main motor 21 starts to be driven, and the roll gap motor 4 starts to be driven to adjust the roll gap of the hull roll 4 to the hull position (initial adjustment). After the initial adjustment is completed, when the operator operates the operation lever 22 from the initial position 37 to the hull sorting position 38, the opening / closing shutter 2 is opened, and the hulling operation by the hulling roll 3 is started and the shaking is started. The moving on / off clutch 24 is turned on, and the swing sorting plate 12 starts swinging.

  The mixed rice of rice bran and brown rice that has passed through the hulling roll 3 is accommodated in the mixed rice tank 10 through the transfer shelf 5, the wind selection unit 6, the mixed rice helix 8, and the mixed rice elevator 9. A set amount of mixed rice is supplied from the mixed rice tank 10 to the oscillating sorting plate 12 through the transfer pad 13, and the sorting operation is performed. The mixed rice discharged from the swing sorting plate 12 is initially in an in-machine circulation state (circulation process). When the amount of mixed rice stored in the mixed rice tank 10 increases and the mixed rice tank first sensor 30 detects the lowering of the mixed rice tank 10, the circulation / discharge switching motor 25 is driven, and the circulation / discharge switching valve 18 is driven. Is switched to the discharge side, and the selected brown rice is supplied to the brown rice elevator 20 and discharged outside the machine (finishing discharge process). When the load current value sensor 29 for detecting the load current value of the main motor 21 detects a load current value greater than or equal to the set value, in addition to the lowering of the mixed rice tank 10 as the timing of the transition from the circulation process to the finish discharge process. Alternatively, the circulation / discharge switching valve 18 may be automatically switched.

  When the mixed rice amount in the mixed rice tank 10 is stored more than the set amount, the sorting state of the slag and brown rice on the swing sorting plate 12 is stable, and at this timing, switching from in-machine circulation to out-of-machine discharge is performed. It is.

  It should be noted that during the circulation process, the operator visually confirms the sorting state of the swing sorting plate 12 before detecting the lowering of the mixed rice tank 10 or more, and if the sorting state is determined to be stable, the circulation / discharge switch 34 is set. By operating, the circulation / discharge switching valve 18 can be switched from the in-machine circulation to the out-of-machine discharge to shift to the finishing discharge process, and the finished brown rice can be discharged out of the machine. As a result, the finished brown rice can be quickly discharged out of the machine (S101).

  When the finishing discharge process is continued and the soot in the soot hopper 1 disappears, the amount of mixed rice in the mixed rice tank 10 decreases and the mixed rice tank 10 rises. When the mixed rice tank second sensor 31 detects the rising of the mixed rice tank 10, the circulation / discharge switching valve 18 is switched from the discharge side to the circulation side, and the process proceeds to a remaining rice processing step for processing the remaining rice. The shift to the remaining rice treatment process is detected by the load current value detection sensor 29 that detects the load current value of the main motor 21 in addition to being detected by the mixed rice tank second sensor 31. Judgment may be made.

The remaining rice treatment step is a step of pulverizing the undepleted rice bran contained in the remaining rice in the machine for a set time so that it is crushed by the rice hull roll 3 to be brown rice and then discharged out of the machine.
Even when the operator manually operates the circulation / discharge switching switch 34 to switch from the in-machine circulation to the out-of-machine discharge and shift to the finish discharge process, the transition from the finish discharge process to the remaining rice processing process is automatically performed. As a result, the operator can automatically shift from the finishing discharge process to the remaining rice processing process without performing any special operation, so that the operability is improved. In addition, when the operator operates the circulation / discharge switching switch 34 during the finishing discharge process to switch the circulation / discharge switching valve 18 from the external discharge to the internal circulation, the operator again sets the circulation / discharge switching switch 34. The circulation process continues until the operation is performed (S102). Thereby, it can prevent switching to discharge | emission outside an apparatus contrary to an operator's intention, and can prevent malfunctions, such as a large amount of rice cakes mixing and discharging | emitting to finishing brown rice. This is performed, for example, when the operator determines that the sorting state of the swing sorting plate 12 has become unstable, or when the operator temporarily stops the removal of the finished brown rice.

  When the remaining rice processing step elapses for a set time (S1), the circulation / discharge switching valve 18 is switched from the circulation side to the discharge side (S2), and the remaining rice is discharged outside the apparatus. When the set time elapses (S3), the circulation / discharge switching valve is switched to the circulation side (S4), and the main motor 21 is stopped (S5).

  When the load current value detection sensor 29 detects a temporary increase in load current value (that is, from the presence of wrinkles to no wrinkles) during the aforementioned remaining rice processing step (S6), the set time of the remaining rice processing step is reset (S7). . This is because the load current value temporarily rises when the operator throws the end amount of cocoon into the hopper 1 just before the end of the hull sorting operation. Thereby, the remaining amount of rice cake can be treated again and discharged outside the machine. At this time, when the presence / absence of wrinkle is not detected and the set time elapses (S1), the circulation / discharge switching valve 18 is switched to the discharge side (S2), and then the mixed rice tank first When the sensor 30 detects that the mixed rice amount equal to or larger than the set amount is stored in the mixed rice tank 10 (S8), the process proceeds to the finishing discharge process. This is because the operator can smoothly continue the rice hull sorting operation when, for example, the next drying machine is put in, not the end amount during the remaining rice treatment process.

  In addition, when the operator operates the circulation / discharge switching switch 34 to switch the circulation / discharge switching valve 18 from the outside discharge to the in-machine circulation at the time of discharging outside the machine in the remaining rice treatment process, the operator again turns on the circulation / discharge switching switch 34. In-flight circulation continues until is operated.

The features of the hull sorter of this embodiment will be further described.
In the hull sorter of the present embodiment, the operation lever 22 has two positions, the initial position 37 and the hull sorting position 38. When the operation lever 22 is operated to the hull sorting position, no further operation is required until the operation is stopped. There is a feature in a certain point. That is, the operation lever 22 is operated until the operation is stopped after the remaining rice treatment process at the time of the transition from the machine circulation to the outside discharge, that is, the transition from the finished rice process to the remaining rice treatment process. The state of the hulling sorting position 38 may be sufficient. Further, there is no need to operate the manual stop switch 40. If the operator returns the operation lever 22 to the initial position 37 after the operation is stopped, the next hull sorting operation can be started, and the number of operations is small and the operability is good.

A circulation / discharge switching switch 34 for manually switching the circulation / discharge switching valve 18 is provided on the side of the hull sorting position 38 of the operation guide guide 41 of the operation lever 22.
Since the circulation / discharge switching switch 34 is provided on the side of the hull sorting position 38 of the operation guide guide 41, there is an advantage that it is easy to operate while looking at the state of the swing sorting plate 12.

Although this embodiment has been described with a hull sorter using a hull roll, a so-called impeller hull sorter can also be used.
In the present embodiment, when it is detected that the amount of mixed rice stored in the mixed rice tank 10 is equal to or less than the set amount during the finish discharge process, there is no wrinkle on the reed hopper 1 or the reed on the reed hopper 1. Although it is determined that the soot in the hopper 1 is less than or equal to the set amount, a soot detection sensor (not shown) is provided in the soot hopper 1, and if the soot detection sensor detects the absence of wrinkles, It may be determined that the amount is less than the set amount.
