The shaft portion 31a of the paddy shutter valve 31 and the shaft portion 29a of the main lever 29 are interlocked and connected with each other by interposing a flexible connecting means 42 with flexibility within a predetermined range.

The gap adjustment of the paddy rolls 8 and 8 is configured to be performed by driving the roll gap adjusting motor M2.

An operation panel 34 is provided in the upper center of the front of the paddy sorter. An operation switch 35, a stop switch 36, and the like are provided in the lower position of the operation panel 34 in the left-right direction. A manual switch 37 for the paddy roll gap that manually adjusts the gap between the paddy rolls 8 and 8 is provided on the upper side of the operation panel 34, and a roll gap that displays the gap position of the paddy rolls 8 and 8 during the paddy operation. A plurality of display units 38 are arranged side by side in the left-right direction (see FIG. 4). That is, each time the roll open switch 37a is pressed, the lamp lighting position moves to the left (when pressed once, the roll gap widens by 0.1 mm), and each time the roll closing switch 37b is pressed, the lamp lighting position moves to the right. (When pressed once, the roll gap narrows by 0.1 mm).

An open switch 37a of the paddy roll gap manual switch 37 is provided on one left and right side of the roll gap display portion 38, and a close switch 37b of the paddy roll gap manual switch 37 is provided on the left and right other sides.

A main motor M for driving the paddy portion 1 and a load current detection sensor 40 for the main motor M are provided. When the load current value based on the detection result of the load current detection sensor 40 exceeds the set value, the paddy rolls 8 and 8 are overloaded with a predetermined amount of widening the gap between the paddy rolls 8 and 8 and the paddy rolls 8 and 8 are set for each set time during the paddy operation. It is possible to control the time to narrow the gap between the two by a predetermined amount.

The graph shown in FIG. 9 is a relationship diagram between the load current and the head supply amount (paddy shutter valve opening), and the same removal state is obtained for fluctuations in the supply amount and roll opening at the same time as the control start. The control unit determines the control line for maintenance.

Further, refer to FIG. 10 for showing the relationship diagram between the load current value and the time.

A mixed rice amount detection sensor (mixed rice tank sensor) 43 for detecting that the mixed rice tank 17 has reached a predetermined amount or more is provided, and the mixed rice amount in the mixed rice tank 17 and the paddy shutter valve 31 are used. It is interlocked with the supply amount, that is, by the paddy shutter valve adjusting means 44.

When the operation switch 35 is operated, the paddy roll initial gap adjusting control means for adjusting the initial gap of the paddy rolls 8 and 8 is controlled by the control unit 47, and the paddy roll initial gap control is set narrower than the standard. There is.

Then, when the mixed rice amount detection sensor 43 detects the amount of mixed rice equal to or larger than a predetermined amount, the control unit 47 controls so as to widen the gap between the paddy rolls 8 and 8 to the standard.

Further, when the mixed rice amount detection sensor 43 detects the mixed rice amount of a predetermined amount or more, the circulation /
When the discharge switching valve 33 switches from the circulation to the discharge side and the circulation / discharge switching valve 33 switches from the circulation to the discharge side, the gap between the paddy rolls 8 and 8 is controlled to be widened to the standard.

If the paddy shutter valve 31 is controlled to be fully opened when the mixed rice amount detection sensor 43 is turned off, overload can be prevented and the removal rate can be stabilized.

Further, in the case of 2-position operation of the main lever 29, the mixed rice amount detection sensor 43 is turned on to automatically discharge the finished rice, but when the removal rate is poor (when the paddy position of the swing sorting plate is high), the finished rice is finished. When the rice partition position is "4 to 5", paddy may be mixed. Therefore, when the finished rice partition position is "1", the initial setting is not performed unless the mixed rice amount detection sensor is ON, and the finished rice discharge is not automatically performed, so that paddy mixing can be prevented.

When the manual switch 37 for the paddy roll gap is operated after the paddy operation is started after the paddy roll initial gap control, the set time of the paddy roll closing adjustment is changed and the mixed rice amount detection sensor 43 exceeds a predetermined amount. The adjustment of the padding roll opening after detecting the amount of mixed rice is regulated.

Therefore, the gap of the paddy roll is adjusted according to the nature of the paddy by changing the set time of the closing adjustment of the paddy rolls 8 and 8 according to the operation of the manual switch 37 for the paddy roll gap of the operator. Can be done.

When the padding work elapses for a predetermined time, in a paddy machine having a function of closing the roll gap, when the operator presses the roll closing switch 37b of the paddy roll gap manual switch 37 in an attempt to increase the removal rate, the roll is rolled. If the control to change the closing time interval to a short time is enabled, stable work can be performed by shortening the interval even if the removal rate does not increase easily.

Further, when the manual switch 37 for the paddy roll gap is operated on the open side, that is, the open switch 37a during the paddy operation, it is controlled to lengthen the setting time for the subsequent closing adjustment of the paddy roll (for example). For each operation, the timer control that operates during the subsequent discharge work is operated by extending the operation time by 1 minute from the initial value). According to this, when the operator judges that the removal rate is high during the paddy operation and operates the manual switch for the paddy roll gap to the open side, the interval of subsequent closing adjustment of the paddy roll is lengthened. It can be adapted to paddy with good detachability.

The main motor M for driving the paddy roll 8 is provided with a load current detection sensor 40 for detecting the load current value, but during paddy operation, that is, after shifting from "circulation" to "discharge" work. When the operator operates the manual switch 37 for the paddy roll gap to the closed side while the removal rate is maintained by the timer control, the roll gap control that works during the subsequent discharge work is the load current value from the timer control. It is configured to switch to load control based on (the paddy roll is opened at a predetermined interval when the load current value exceeds a predetermined value). According to this, control based on the load current value is possible, and the detachability can be maintained.

In addition, if the work load drops from the predetermined minimum line (specified value) of the load current value while maintaining the removal rate by timer control after shifting from "circulation" to "discharge" work, The detachability can be maintained even in the control in which the roll gap control that works during the subsequent discharge work is operated by switching from the timer control to the load control. In short, if it is judged that the removal rate is low during work and the roll gap is narrowed, it is judged that the paddy has poor removal property, and the timer control during work is changed to load control to maintain the removal property. can do.

Furthermore, after shifting from "circulation" to "discharge" work, when the removal rate is maintained by timer control, if the work load rises above the specified value of the load current value predetermined from the initial stage of work, it is specified. It is possible to maintain the detachability during work by controlling the roll gap "closed" output by timer control until it becomes less than the value.

In the above configuration, when the work load rises above the specified value of the load current value determined in advance from the initial stage of work start, the roll gap “open” output may be performed so as to be equal to or less than the specified value.

In paddy control, after the initial setting of the roll gap, grains are accumulated in the mixed rice tank 17, and when the mixed rice tank lower limit sensor detects and automatically switches from the "circulation" state to the "discharge" operation, the lower limit sensor The detachability can be maintained by controlling the time lag of several seconds without switching immediately after the detection.

In paddy control, it takes a few seconds (minutes) without immediately switching from a state that satisfies the specified value to the control standard that was decided in advance when shifting from the "discharge" work to the "circulation" work and starting the remaining rice processing. By controlling so as to provide a time lag, when the capacity of the mixed rice tank is increased, the amount of accumulated rice in the mixed rice tank is large when the residual rice treatment is started, so that the residual rice treatment is not completed forever. , The amount of accumulated rice in the mixed rice tank can be maintained properly.

In paddy control, when the operator presses the roll gap open switch, the timer control that operates during the subsequent discharge work is controlled to operate by extending the operation time by 1 minute from the initial value. For example, if it is judged that the removal rate is high at the time of work and the roll gap is widened, it is judged that the paddy has good removal property and the timer time during the work is operated for a long time. Leads to maintaining.

As shown in FIG. 7, a switch group and a sensor group are connected to the input side of the control unit, and motors are connected to the output side to control each part of the paddy machine.

Next, it will be described based on the flowchart shown in FIG.

When the operation switch of the paddy sorter is turned on, the paddy roll gap is initially set. Then, the main lever (operation lever) is operated from the initial position to the circulation / discharge position, the paddy operation is started, and the circulation operation state is established. Therefore, when the full amount of the mixed rice tank is detected, the circulation / discharge switching valve is switched from circulation to discharge, and the finished brown rice discharge operation state is reached after the paddy roll set time opening adjustment is performed. Then, in the case of detection without mixed rice in the mixed rice tank, the circulation / discharge switching valve switches from discharge to circulation and circulates for a set time. Then, the circulation / discharge switching valve is switched from circulation to discharge, and the operation is stopped after the set time elapses.
