  First, based on FIG. 1, the whole structure of the hull sorter which comprises this invention is demonstrated.

  The rice hull sorter has a rice hull portion 1 arranged at the front upper part of the machine body, a slashed rice wind sorting part 2 arranged at the front lower part of the machine body, and a swing rice plate type mixed rice sorter arranged at the rear side part of the machine body. Part 3 is composed of a mixed rice cerealing machine 4 for cerealing the crushed rice, and a brown rice cerealing machine 5 for taking out the brown rice out of the machine.

  The hulling portion 1 is constituted by a hulling hopper 6, a hulling chamber 8 in which hulling rolls 7 and 7 are installed, and the like. The sliding rice wind selection unit 2 includes a sliding rice wind selection box 9, a sliding rice sorting air passage 10 that is obliquely arranged in the front-rear direction in the sliding rice wind selection box 9, and a sliding rice selection air passage. 10 is arranged at the end of the crushed rice sorting air passage 10, the cullet receiving trough 11 provided below the midway portion 10, the crushed rice receiving trough 12 provided below the starting end portion of the crushed rice sorting air passage 10. It is comprised by the tang 13 and the dust exhaust cylinder 14 etc. which were installed.

  Next, the oscillating sorting type mixed rice sorting unit 3 will be described. The multistage oscillating sorting plates 15 are formed with irregularities for sorting on the plate surface, with one side in the horizontal direction as the high supply side and the other side as the low discharge side, and the vertical direction perpendicular to the horizontal direction. The rocking sorting plate 15 is inclined in both the vertical and horizontal directions, with one side being a high rocking side and the other side being a low rocking side, and the rocking sorting plate 15 is composed of a rocking arm and a rocking link. It is configured to be reciprocally swung up and down in the horizontal direction by a swinging device.

  A supply port is formed on the supply side of the swing sorting plates 15,..., And the mixed rice wind-selected by the sliding rice receiving tray 12 is mixed rice masher 4, mixed rice tank 24, and distribution supply basket. 16 and the distribution case 17 are supplied to the swing sorting plates 15. The mixed rice supplied to the oscillating sorting plates 15, ... has a grain size, specific gravity, friction coefficient, etc., so that small brown rice with heavy specific gravity is distributed in a drifting manner on the rocking side and compared with brown rice Thus, large and light specific rice cakes are distributed while drifting to the underside, and mixed rice of rice cake and brown rice that is not separated is distributed in the middle. These selected grains are separated and extracted by the brown rice partition plate 18 and the straw partition plate 19 provided on the discharge side of the swing sorting plate 15.

  The extracted brown rice is taken out of the machine through the brown rice extraction gruel 20, the brown rice channel 21, and the brown rice cerealing machine 5.

Moreover, the taken-out rice cake is returned to the rice huller 1 through the rice cake removing rice cake 25, the rice cake passage 26, and the rice hulling machine 27, and is re-cooked.

  Next, the roll gap control device for the hulling rolls 7 and 7 will be described with reference to FIGS.

  FIG. 2 shows a known roll gap adjusting means for the hulling rolls 7 and 7. The left hulling roll 7 is a main hulling roll that is driven at a fixed position, and the right hulling roll 7 is a sub hulling roll that is pivoted on the guide arm 7a. The auxiliary hull roll is configured so that the gap with the main hull roll can be freely opened and closed by the roll gap adjusting means 7b. By rotating the roll gap adjusting motor 28 forward and backward, the roll gap adjusting means 7b is driven forward and reverse. Thus, the guide arm 7a is rotated clockwise or counterclockwise, and the roll gap between the main and sub hulling rolls 7 and 7 is adjusted to be opened and closed. The roll gap adjusting handle 7c can be manually rotated and the roll gap adjusting means 7b can be driven forward and backward to adjust the opening and closing of the roll gap.

  On the input side of the controller 40 having a built-in CPU, a load current sensor 30 for detecting the load current value of the main motor 29, a power supply voltage sensor 31 for detecting the original power supply voltage, and an oscillation sorting plate 15 are connected via an input interface. A swing rotation speed sensor 32 for detecting the swing rotation speed, a valve opening sensor 34 for detecting the valve opening degree of the hull supply regulating valve 33 of the hulling portion 1, and a hull sensor for detecting the presence or absence of grains in the hull hopper 6 43, roll gap initial setting switch 44, operation / stop switch 35, roll gap opening adjustment switch 36, roll gap closing adjustment switch 37, automatic / manual changeover switch 38 for switching automatic / manual of the roll gap control device, display changeover A switch 39 is connected.

  Further, the main motor 29, the roll gap adjusting motor 28, and the valve opening degree adjusting motor 41 are connected to the output side of the controller 40 via an output interface and a drive circuit.

  Next, the control content of the roll gap of the controller 40 will be described based on the flow of FIG.

  When the power switch (not shown) is turned on at the start of the initial hulling operation, the control is started, and when the roll gap initial setting switch 44 is turned on or off, the flag of the roll gap initial setting switch 44 is “main motor” with FG = 1. "Mode for executing initial setting of roll gap every time of starting 29" or "Mode for executing initial setting of roll gap only at first startup of main motor 29" with FG = 2 (step 1) ). Next, it is determined whether the main motor 29 is ON / OFF (step 2). If the main motor 29 is ON, the roll gap initial setting mode is determined, and the flag is initialized every time the main motor is started with FG = 1. In the mode for executing the setting, initial setting control of the roll gap of the hulling rolls 7 and 7 is performed (step 4).

  The roll gap initial setting control is executed, for example, as follows. First, when the roll gap is adjusted to be open and the load current value detected by the load current sensor 30 no longer changes, it is determined that the hulling rolls 7 and 7 are not in contact with each other, and the roll gap opening adjustment is stopped. When the roll gap is adjusted to close and the load current sensor 30 detects an increase in the load current value, it is determined that the pallet rolls 7 and 7 are in minute contact, and the roll gap closing adjustment is stopped, and then the roll gap is set for a predetermined time. The opening is adjusted and adjusted to a predetermined initial roll gap (for example, 1 mm).

  When the roll gap initial setting control is executed, the flag is changed to FG = 0 which has already been executed (step 5), and then the timer time (T) of timer-controlled roll gap control is set (step). 6). Next, the presence / absence of a soot in the soot hopper 6 is determined from the detection information of the soot sensor 43 (step 7). If so, the opening / closing of the soot supply control valve 33 is determined from the detection information of the valve opening sensor 34. (Step 8), when the saddle feed control valve 33 is adjusted to open, the timer time in the timer control type roll gap control is subtracted (Step 9), and then the remaining time of the timer time is calculated every predetermined time. (Step 10) It is determined whether or not the remaining timer time is 0 (Step 11). When the remaining timer time becomes 0, a predetermined roll gap closing adjustment command is issued from the controller 40, and the roll gap adjusting motor 28 is operated. One pulse is closed and the roll gap is closed. Next, the next timer time (T) in the timer control is set, and the roll gap control by the timer control is performed (step 13). Next, it is determined whether the main motor 29 is ON / OFF. Control continues.

  Further, when the roll gap initial setting switch 44 is turned OFF, the flag is switched to “mode for executing the roll gap initial setting only when the main motor is started for the first time” with FG = 2. When control is started in this state, it is determined that the initial setting mode is FG = 2 and the roll gap initial setting is executed only when the main motor is started for the first time (step 3), and then the initial setting mode is FG. = 1 or not (step 15), and in this mode, the roll gap initial setting is executed only when the main motor is started for the first time. Therefore, the initial setting control is omitted during the resuming operation. Is executed.

  When the mode for executing the initial setting is selected every time the main motor is started by turning on the roll gap initial setting switch 44, the timer time of the timer control is reset when the main motor 29 is turned off. Also, if the roll gap initial setting switch 44 is turned off and the mode for executing the roll gap initial setting only when the main motor is started for the first time is selected, the reset of the timer time by the timer control is stopped when the main motor 29 is turned off. Then, the timer time is temporarily stopped. Then, when the main motor 29 is subsequently turned on and the next hulling operation is resumed, the time measurement of the remaining timer time is resumed.

  Therefore, in the mode in which the roll gap initial setting is executed only when the main motor is started for the first time, the timer time in the timer-controlled roll gap control is determined by the sum of the previous timer time and the current timer time. When the timer period expires, the roll gap is closed and adjusted.

  As described above, when controlling the roll gap of the hulling roll, either the roll gap initial setting by the roll gap initial setting switch 44 every time the main motor is started or the roll gap initial setting only when the main motor is started for the first time. Therefore, it is possible to use in accordance with the operator's desired usage and proficiency level, and at the time of resuming hulling work, the hulling work can be resumed with the same roll gap as at the time of the previous hulling work.

  Next, another embodiment of the roll gap control will be described with reference to FIG.

  When the power switch (not shown) is turned on at the start of the initial hulling operation, the control is started. When the roll gap initial setting switch 44 is turned on or off, the flag of the roll gap initial setting switch 44 is set to “main” of FG = 1. "Mode for executing initial setting of roll gap every time motor 29 is started", or "Mode for executing initial setting of roll gap only when main motor 29 is first started" with FG = 2 (step 1).

  Next, it is determined whether the main motor 29 is ON / OFF (step 2). Next, when the main motor is ON, a roll gap initial setting mode is determined (step 3). If the flag is in a mode in which the initial setting is executed every time the main motor is started with FG = 1, the roll gap initial setting control is performed (step 4), and then the roll gap initial setting flag has been executed. = 0 (step 5). Next, roll gap maintenance control for performing the hulling operation while maintaining a predetermined roll gap is started (step 6), and the roll gap maintenance control is continued (step 7).

  In this roll gap maintenance control, a predetermined timer time is set in the roll gap maintenance control by timer control, and when the timer time expires, the roll gap is closed and adjusted by a predetermined gap to maintain the predetermined roll gap. It is done. Further, control for maintaining a predetermined roll gap may be performed based on the load current value reference. That is, the load current value of the hulling roll driving main motor 29 is detected by the load current sensor 30 every predetermined time, and the roll gap is opened and closed so as to maintain the detected load current value at a predetermined reference value. The gap is maintained.

  Next, ON / OFF determination of the main motor 29 is made (step 8). If the main motor 29 is ON, the process returns to step 7 and the roll gap maintenance control is continued. If the main motor 29 is OFF, the roll gap maintenance control is completed (step 9), and then the roll gap initial setting mode is determined (step 10). When the main motor is started with FG = 1. In the mode in which the initial setting is performed every time, the roll gap of the hulling roll is adjusted to open for a predetermined time to widen the roll gap (step 11), and the roll gap is set only when the main motor is first started with FG = 2. In the case of the initial setting mode, the control is terminated with the roll gap as it is.

  If the roll gap initial setting mode is determined (step 3) and the flag is set to the initial setting of the roll gap only when the main motor is started for the first time with FG = 2, then the flag is set to FG =. Whether or not 1 is determined and FG = 1 is not satisfied, the roll gap maintenance control is performed without executing the initial setting of the roll gap (step 7).

  Therefore, when controlling the roll gap, the roll gap is set at the end of the operation as described above in relation to the selection of execution at the start of the main motor with the initial setting of the roll gap or only when the main motor is started for the first time. Can be widened by adjusting the opening, or the roll gap can be selected as it is, and the hulling operation can be resumed smoothly with the same roll gap as the previous hulling operation.

  Next, another embodiment of the roll gap control will be described with reference to FIG.

  When a power switch (not shown) is turned on at the start of the initial hulling operation, control is started, and the roll gap initial setting switch 44 is turned on or off. Then, the flag of the roll gap initial setting switch 44 is FG = 1 “mode for executing the initial setting of the roll gap every time the main motor 29 is started”, or FG = 2 “only when the main motor 29 is started for the first time. Is switched to “mode for executing initial setting of roll gap” (step 1).

  Next, it is determined whether the main motor 29 is ON / OFF (step 2). If the main motor is ON, then the roll gap initial setting mode is determined (step 3). If the flag is in a mode for executing the initial setting of the roll gap every time the main motor is started with FG = 1, the roll gap initial setting control is performed (step 4), and the initial setting of the roll gap initial setting flag is executed. FG = 0 already changed (step 5).

  Next, when the load current value of the main motor 29 exceeds the reference load current value (step 6), it is then determined whether or not the soot supply adjustment valve 33 is adjusted to open (step 7). When the opening is adjusted, the process shifts to a stable waiting stroke process for a predetermined time (T1) (step 8), and a hulling operation is performed in which the roll gap set in the roll gap initial setting is fixed for a predetermined time. When a predetermined time (T1) of the stable waiting hull stroke is completed, a reference load current value for roll gap control based on a load current value reference corresponding to the valve opening degree of the hull supply control valve 33 is calculated by a predetermined calculation formula. (Step 9).

  Next, the load current value (I) of the main motor 29 is detected (step 10), the reference load current value and the detected load current value (I) are compared (step 11), and the detected load current value (I) is calculated. When it is large, the roll gap is adjusted to open (step 12). When the detected load current value (I) is small, the roll gap is closed (step 13), and the detected load current value (I) is set. ) And the reference load current value are equal, control for maintaining the roll gap is performed without adjusting the opening and closing of the roll gap.

  Next, ON / OFF determination of the main motor 29 is made (step 14). When the main motor is ON, the process returns to the step 10 to continue the roll gap control based on the load current value reference. When the main motor is OFF, Returning to step 2, the control is continued.

  Further, in the determination of the roll gap initial setting mode in step 3, when the roll gap initial setting mode is a mode for executing the initial setting of the roll gap only when the main motor of FG = 2 is first started, It is determined whether or not the flag is FG = 1 (step 15). If FG = 1 is not satisfied, it is then determined whether or not the soot supply control valve 33 is adjusted to open (step 16). When the opening is adjusted, the process shifts to a stable waiting stroke for a predetermined time (T2) (step 17), and when the predetermined time (T2) ends, the process shifts to step 10 to control the roll gap based on the load current value reference. Is made.

  The predetermined time (T2) of the stable waiting stroke process in step 17 is set shorter than the predetermined time (T1) of the stable waiting stroke process in step 8 performed after the initial setting of the roll gap.

  As described above, when the mode for executing the initial setting of the roll gap only at the first start of the main motor by the roll gap initial setting switch 44 is selected, the initial setting of the roll gap is omitted at the second and subsequent startups of the main motor, It is possible to restart the hulling operation by shortening the time of the stable hulling process. Therefore, it is possible to quickly resume the hulling operation while maintaining the roll gap at the previous operation. It should be noted that during the resumption hulling work, the grains remain in the grain circulation portion of the hulling sorter and the work is stabilized quickly, so there is no problem even if the predetermined time of the stable waiting hulling process is shortened.

  Next, another embodiment of the brown rice masher 5 will be described with reference to FIGS.

  The brown rice cerealing machine 5 is constituted by a bucket type elevator, and is pivotally supported by a pulverizer base 51 provided at the rear part of the sliding rice-style sorting box 9 so as to be rotatable around a vertical axis 51a. The brown rice cerealing machine 5 includes a cerealing case 5a, an elevating belt 5c with buckets 5b wound around upper and lower pulverizing pulleys in the cerealing case 5a, and a brown rice throwing hole 5d. .

  In the operating state, as shown in FIG. 7 (1), the brown rice cereal case 5 a protrudes backward so that the power from the main motor 19 is transmitted through the transmission shaft 52 and the belt transmission device 53 to the lower pulley. It transmits to the axis | shaft 54, the brown rice masher 5 is driven, and it is comprised so that a brown rice brown rice may be thrown out toward the back from the brown rice throwing hole 5d.

  Further, in the retracted state, as shown in FIG. 8, the brown rice masher 5 is configured to be rotatable and fixed along the rear side wall 9 a of the brewed rice-style selection box 9. And as shown in FIG. 9, the opening part 55 for cleaning is comprised in the lower part of the brown rice cereal case 5a, and the state in which the brown rice cereal case 5b protruded back of the working state is carried out by the pulverizer base 51. When the opening 55 is closed and rotated to the retracted state, the opening 55 is displaced from the masher base 51 and opens, so that residual grains can be taken out from the opening 55 and cleaned. Moreover, at the time of carrying the rice hull sorter, the brown rice cerealing machine 5 is set in the retracted state to reduce the size of the machine body and thereby reduce the transportation cost.

  Further, in order to pivotably support the brown rice cerealing machine 5 on the cerealing machine base 51 provided at the rear side end portion of the sliding rice style selection box body 9, A vertical axis 51a is attached to the lower part via a bracket 56, a shaft hole 57 into which the vertical axis 51a can be fitted is formed on the side of the whipping machine base 51, and the cereal case 5a is moved up and down in the direction of the arrow, The longitudinal axis 51a on the grain case 5a side is attached to and detached from the shaft hole 57 on the grain mill base 51 side. Thus, the brown rice cerealing machine 5 can be easily attached to and detached from the brewed rice-style sorting box 9 of the rice hull sorter, and can be easily changed between the working state and the stored state.

  Moreover, as shown in the said FIG. 9, the protruding state which pivotally supported the masher base 51 to the periphery of the horizontal axis 58 with respect to the sliding rice-style selection box 9, and rotated the masher base 51 downward, The storage state may be changed so as to be rotated upward. A pressing spring 59 is attached to the horizontal shaft 58, and the cerealing machine base 51 is urged to rotate upward. Thus, the brown rice outlet 61 is closed by the cerealing machine base 51 rotated upward, so that intrusion of mice and the like can be prevented.

  Next, the locking structure of the protective cover 62 of the sliding rice-style sorting box 9 will be described with reference to FIG.

  A protective cover 62 is detachably attached to the side surface of the sliding rice-style box 9. An opening 62a is provided at, for example, the lower end of the protective cover 62, and a handle 63 made of, for example, a synthetic resin is fitted and attached to the opening 62a to reinforce the lower portion of the cover. 64 is formed integrally. Moreover, the latching recessed part 65 is provided in the inner side part of the sliding rice style selection box body 9 via the bracket. Thus, the side opening of the brewed rice-style sorting box 9 is closed with the protective cover 62, and the locking portion 64 integrally attached to the handle 63 is fitted into the locking recess 65, so that the sliding The protective cover 62 is locked to the rice-style box 9.

  In the conventional apparatus, since the handle 63 is configured by welding and integrating a locking portion formed of a round bar, the number of parts is increased and the cost is increased. However, as described above, since the handle 63 with the locking portion 63 that is integrally formed is fitted and attached to the opening 62a of the protective cover 62, the number of parts can be reduced while increasing the strength of the protective cover 62. The cost can be reduced.

  This locking device is not limited to the hull sorting device or the locking device for the protective cover 62, and can be widely applied to the locking device for the cover of other agricultural machines.

  Next, another embodiment of the bowl receiving rod 11 will be described with reference to FIG.

  In the middle part of the crushed rice sorting air passage 10, a cocoon receiving plate 11 is provided. A culling sorting air passage 71 is provided along the lower side of the crushed rice sorting plate 10 of the crushed rice sorting air passage 10. The sorting air that has flowed into the start end of the sluice flows through the lower part of the midway catch 11 and flows to the end side, and then flows into the tang 13.

  A bypass valve 72 is pivotally supported at the end portion of the soot sorting air passage 71 so that the soot can be opened and closed. When the bypass valve 72 is fully closed, the sorted soot can be taken out from the soot receptacle 11 via the soot sorting air passage 71 into the soot pool.

  A rotation speed adjusting means 73 is provided in the tang 13.
