Explaining the configuration for changing and adjusting the distance between the pulley parts (41a) and (41b), the sliding pulley part (41a)
First attached to the boss of the bearing using a bearing (46)
With the rotation of the first cam forming member (47), the cam forming member (47) and the second cam forming member (48) attached to the fixed frame side of the threshing device (2) respectively, Both pulley parts
Cam protrusions (47a) and (4a) to move (41a) and (41b)

(M ₁ ) and the electric motor (M ₂ ) for adjusting the air flow rate of the above-mentioned Kara Minoh (14)
A control configuration for controlling the sorting state of the sorting device (B) by activating the above will be described.

As shown in FIG. 1, a control device (55) utilizing a microcomputer is provided, and the control device (55) detects whether or not the transmission (9) for traveling has been operated to the reverse side. buck switch (S _6), the strain based sensors (S _0), the engine rotational speed sensor (S ₇₎ for detecting the rotational speed of the engine (E),
The vehicle speed sensor (S ₁ ), the toumi rotation speed sensor (S ₄ ), the chaff opening detection potentiometer (S ₂ ), the toumi air volume detection potentiometer (S ₃ ), and the chaff opening at the same vehicle speed are increased or decreased. To adjust the chaff opening potentiometer (S ₈ ), tomi airflow potentiometer to adjust the toumi airflow at the same vehicle speed (S ₉ ), and to indicate whether the culm is rice or wheat. Each of the grain culm type selection switches (S ₁₀ ) as the grain culm type instructing means is connected.

Incidentally, in FIG. 1, (56) is a liquid crystal display unit for displaying the selection state of the above-mentioned Tomi air volume, chaff opening, etc. in a bar graph manner, and (57) is a display on the display unit (56). It is a push button type display state changeover switch for selectively switching the state between the toumi air volume and the chaff opening degree, and although not described in detail, the display state of the toumi air volume and the chaff opening degree display state each time it is pressed. It is designed to switch between and.

Then, the control device (55), based on the information preset and stored and various input information, the both electric motor
By controlling the operation of (M ₁ ), (M ₂ ), the chaff opening is performed so that the sorting state of the sorting device (B) is maintained in an appropriate state corresponding to the throughput of the threshing device (2). It is configured to automatically adjust the degree and the air flow rate.

However, in the combine, the amount of processed material in the threshing device (2) becomes larger as the mowing speed increases, so in the present embodiment, the fact that the processed material amount and the vehicle speed have a comparative relationship is used. Specifically, based on the detection information of the vehicle speed sensor (S ₁ ), the sorting state of the sorting device (B) is automatically adjusted so that the sorting state corresponding to the larger amount of processed material becomes higher as the vehicle speed increases. Is configured.

In addition, as shown in Fig. 3 (a), basically, as the vehicle speed increases, the sorting state corresponding to the state in which the amount of leaked material is large, that is, the interval (s) between the chaff sheaves (21)
The vehicle speed sensor (S ₁ ) is increased so that (hereinafter sometimes abbreviated as chaff opening) becomes large and the air flow rate of the Karato (14) (hereinafter sometimes abbreviated as toumi air flow) becomes large. ), The chaff opening and the toumi air volume are automatically adjusted.

Also, even at the same vehicle speed, the actual amount of leaked material may differ due to the difference in the grain setting state of the grain culm, so that it is possible to change the chaff opening and toumi air volume at the same vehicle speed. There is.

In addition, the chaff opening adjustment potentiometer (S ₈ ) and the toumi air flow adjustment potentiometer (S ₉ )
By manually setting the target selection state at the maximum vehicle speed by each of the above, and by using the manually set target selection state as a reference, and correcting the reference selection state according to the vehicle speed, The state of sorting is set to the state of sorting according to the amount of the processed leakage material (see FIGS. 3 (b) to (e)).

However, since the proper selection state is different even if the grain culm to be treated is rice and wheat even if the treatment amount is the same, based on the information of the grain culm type selection switch (S ₁₀ ), The map of the correction value according to the vehicle speed is automatically selected and switched between rice (f ₁ ) and wheat (f ₂ ). Then, in this embodiment, the vehicle speed is set to four reference values (V ₁ ), (V ₂ ),
It is divided into five zones based on (V ₃ ), (V ₄ ), and the same chaff opening or the same toumi air volume is maintained in each zone. The speed difference between the maximum value and the minimum value of each zone is set to be the same (Fig. 3 (b), (c)).
reference).

Further, as the vehicle speed is reduced more than the value set based on the speed difference, the electric motor for adjusting the interval is
(M ₁ ) is operated with a set delay time (for example, 10 seconds), and the air flow rate adjusting electric motor (M ₂ ) is operated without delay time. The value of the delay time is the time during which the cut culm is conveyed to the threshing device (2), and
It is set in consideration of the time required for the supplied grain culm to be handled.

However, if the grain culm is wet, it will be difficult for the grain to pass through the interval (s) of the chaff sheave (21), so as described in detail later, the interval (s) is opened regardless of the amount of processed material. It is maintained in a state of being adjusted to the maximum value on the handle side, and the toumi air volume is maintained at the target value set by the potentiometer for adjusting the air volume of the toumi (S ₉ ).

Furthermore, during non-mowing work on a headland where the stock sensor (S ₀ ) is in the OFF state or when the vehicle is backing up when the back switch (S ₆ ) is in the ON state, the amount of leaked material is reduced regardless of the vehicle speed. The selected state is set in advance in correspondence with the small number. When operating in a preset sorting state, the interval adjusting electric motor (M ₁ ) is operated with a delay time, and the air flow rate adjusting electric motor (M ₂ ) is operated without delay time. Is done.
However, the delay time is set so that the set value of rice (t ₂ ) is larger than the set value of wheat (t ₂₀ ) (Fig. 13).
(See (a) and (b)). Furthermore, since the proper selection state in the state where the amount of processed material is small is different between rice and wheat, based on the information of the grain culm type selection switch (S ₁₀ ), the chaff opening as a whole is higher in wheat than in rice. Becomes smaller (Fig. 3
(See (d)) On the other hand, in the case of rice, the air flow of Tomi is reduced to be smaller than that when the stock sensor (S ₀ ) is in the ON state,
Moreover, in wheat, the air flow rate at the time when the stock origin sensor (S ₀ ) changes from ON to OFF is maintained.

Incidentally, the potentiometer for adjusting the target value when the maximum vehicle speed _{(S 8), (S 9} ) the lower limit of the adjustable range of each, in order to prevent clogging of the culms by erroneous operation, the gap (s)
It is set to a range that is larger than the set value, which is larger than the fully closed state in which is zero and the state in which the toumi air volume is zero.

That is, using the control device (55), the process of determining whether or not the grain culms are in a wet state based on the set value of the chaff opening adjustment potentiometer (S ₈ ) is It corresponds to the grain culm state indicating means (102) for instructing whether or not the grain culm supplied to the room (A) is in a wet state. Also, by using the control device (55), the handling room (A)
Processed material amount detecting means (10) for detecting the amount of processed material supplied to
0) is configured, and the processed material amount detecting means (100)
And a control means (101) for operating the distance adjusting electric motor (M ₁ ) and the air flow adjusting electric motor (M ₂ ) based on various information such as information of the grain culm state indicating means (102) and the like. Will be configured.

The operation of the control device (55) will be described below.

As shown in FIG. 2 (a), when the control device (55) is started when the power is turned on, first the initialization process is executed,
Next, execute the process of reading the data of each sensor,
After that, an output process and a target value setting process for actually operating the electric motors (M ₁ ) and (M ₂ ) are executed. After the initialization process is performed, the processes from the process of reading the data of the sensors are repeated until the power is turned off.

Explaining the output processing, as shown in FIG. 2B, first, the threshing clutch (7) is in the ON state,
In addition, it is determined whether or not the toumi rotation speed is equal to or higher than the set rotation speed (set to 500 rpm). That is, it is determined whether or not the sorting process is possible and the toumi air volume can be changed and adjusted.

Therefore, when the threshing clutch (7) is OFF, the processing of the toumi stop output and the chaff stop output is executed to stop the adjustment of the toumi air volume and the chaff opening, and this output processing is completed. Will be done.

When the threshing clutch (7) is ON and the toumi rotation speed is equal to or higher than the set rotation speed, after performing an output process for changing and adjusting the toumi air volume, the chaff opening degree is continuously changed and adjusted. The output process for executing is executed.

Explaining the output process of the Toumi air volume, first,
It is determined whether or not the toumi stop flag for stopping the adjustment of the toumi air volume is ON, and if it is ON, a tomi stop output process is executed to maintain the toumi air volume at the current air volume.

When the toumi stop flag is OFF, it is determined whether or not the toumi weak flag indicating that the toumi air volume is operated to the weak side is OFF, and when it is OFF,
Subsequently, it is determined whether or not the toumi strong flag indicating that the toumi air volume is operated to the strong side is OFF.

Both the toumi weak flag and the toumi strong flag are O.
In the case of FF, the toumi deviation for determining whether to maintain or increase or decrease the toumi air volume at the current value,
Obtained by subtracting the current value detected by the toumi air volume detection potentiometer (S ₃ ) from the target value set in the target value setting process described below, and determine whether the toumi deviation is within the set dead zone. Determine.

If the Toumi deviation is on the strong side, or if the Toumi weak flag is ON, the transmission of the Karin (14)
Switch (54b) that detects when (42) has reached the gear shift lower limit
It is determined whether or not is ON. Then, when the switch (54b) is OFF, a weak tomi output process is executed to operate the air flow rate adjusting electric motor (M ₂ ) so as to reduce the toumi air volume. On the other hand, when the toumi deviation is on the weak side, and the toumi strong flag is ON.
If it is, it is determined whether or not the switch (54a) for detecting that the transmission (42) of the Karashino (14) has reached the upper limit of gear shifting is ON. Then, the switch (54a) is turned off.
In the case of FF, a strong toumi output process is executed to operate the blow rate adjusting electric motor (M ₂ ) so as to increase the toumi air volume. However, when the Toumi deviation is within the dead zone, or the switches (54a), (54b)
If one of them is ON, the toumi stop output process is executed to maintain the current air flow rate.

After executing the process for adjusting the air volume of the Karato (14), in order to execute the process for adjusting the chaff opening,
First, it is determined whether or not the chaff stop flag for stopping the adjustment of the chaff opening is ON, and if it is ON, a chaff stop output process is executed to maintain the chaff opening at the current opening. To do.

If the chaff stop flag is OFF, it is determined whether or not the chaff closing flag indicating that the chaff opening is operated to the closing side is OFF, and if it is OFF, the chaff opening is continued. It is determined whether or not the chaff opening flag, which indicates that the cuff opening flag is open, is OFF.

Both the chaff closed flag and the chaff open flag are O.
If it is FF, the chaff deviation for determining whether to maintain the chaff opening at the current value or to increase or decrease the chaff opening,
Obtained by subtracting the current value detected by the chaff opening potentiometer (S ₂ ) from the target value set in the target value setting process described below, and whether the chaff deviation is within the set dead zone. To determine.

A switch (40b) for detecting that the interval (s) of the chaff sheave (21) has reached the lower limit on the closing side when the chaff deviation is on the opening side or the chaff closing flag is ON. It is determined whether or not is ON. When the switch (40b) is OFF, the interval (s)
Electric motor for adjusting the chaff opening so that
The chaff closed output process for activating (M ₁ ) is executed. On the other hand, when the chaff deviation is on the closed side and when the chaff opening flag is ON, the chaff sheave (2
It is determined whether or not the switch (40a) that detects that the interval (s) in 1) has reached the upper limit on the open side is ON. Then, when the switch (40a) is OFF, a chaff opening output process for operating the chaff opening adjustment electric motor (M ₁ ) to operate the interval (s) to the open side is executed. . However, if the toumi deviation is within the set dead zone, or if one of the switches (40a) and (40b) is ON, the chaff stop output processing is executed to maintain the current opening. I will let you.

The process for setting each flag will be described in detail later when the process in the automatic mode is described.

Next, the target value setting process for setting the target value of the toumi air flow rate and the target value of the chaff opening will be described with reference to the flowchart shown in FIG.

First, in order to repeatedly execute the target value setting process every time the set time elapses, that is, in order to update various data for controlling the selection state every set time, It is determined whether or not the set time (500 ms) has elapsed, and the target value setting process is executed only when the set time has elapsed.

When the set time has elapsed, it is specially provided as an input terminal of the control device (55) in order to activate a check mode for checking the operation of the control device (55) at the time of manufacture. It is determined whether or not the signal (CK-3) of the checked terminal (not shown) is ON,
When it is OFF, it is determined whether or not it is a fine adjustment mode provided so that the toumi air volume and the chaff opening can be manually adjusted.

Although not described in detail, the fine adjustment mode is set in the display unit.
Display state changeover switch to change the display state of (56)
With the (56) turned on, turn on the main switch (not shown) for starting power supply to the control device (55).
When it is operated N times, it is automatically activated.

Then, in the case of the check mode or in the fine adjustment mode, the processing of the check mode described later is executed.

If neither the check mode nor the fine adjustment mode, is the adjustment value by the above-mentioned potentiometer for adjusting the chaff opening (S ₈ ) larger than the set value (4.4 V) close to the maximum value (5 V) on the opening side? If it is larger than the set value,
When the grain culm is wet, the sorting state is automatically set (hereinafter referred to as the wetting mode). If the sorting value is smaller than the set value, the sorting state is automatically adjusted according to the vehicle speed corresponding to the amount of processed material. The control mode is automatically switched based on the value of the chaff opening adjustment potentiometer (S ₈ ) so that the automatic mode is set. That is, based on the value of the chaff opening adjusted by the chaff opening potentiometer (S ₈ ), the control device
(55) the process of switching the operation mode between the wet mode and the automatic mode, the grain culm state instructing means for instructing whether or not the grain culm supplied to the handling room (A) is in a wet state (102) )
Will correspond to.

Explaining the check mode, the check mode is provided for confirming the operating state of each of the toumi air volume and the chaff opening, and for adjusting and inspecting the operating range at the time of manufacture. And Fig. 2
As shown in (d), when this check mode is activated, each of the toumi air volume and the chaff opening is adjusted to the toumi air volume adjusting potentiometer (S ₉ ) and the chaff opening adjusting potentiometer (S ₈ ). The respective flags are set on the basis of the respective values of the potentiometers (S ₈ ) and (S ₉ ) so that the flags have the values set by the respective.

That is, when the adjustment value by the potentiometer for adjusting the chaff opening (S ₈ ) is equal to or less than the set value (0.2 V) on the fully closed side, the interval (s) between the chaff sheaves (21) becomes the minimum. The chaff closing flag is turned on and the chaff opening flag is turned off so that the state is brought into the state. When the adjustment value is equal to or more than the setting value (4.8V) on the fully open side, the chaff sheave (2
The chaff closing flag is turned off and the chaff opening flag is turned on so that the interval (s) of 1) becomes the maximum fully opened state.
N

However, when the adjustment value is between the set value on the fully closed side and the established value on the fully open side, the chaff closing flag and the chaff opening flag are turned off, and the target value of the chaff opening is set. , The chaff opening adjustment potentiometer (S ₈ ) based on the adjustment value. The relationship between the adjustment value and the target value is in direct proportion.

When the target value of the chaff opening and the setting of the flag are completed, the potentiometer for adjusting the toumi air volume is similarly obtained.
The target value and flag of the toumi air volume will be set based on the adjustment value by (S ₉ ).

In addition, if the adjustment value by the potentiometer for adjusting the air volume of Sumi (S ₉ ) is less than or equal to the set value on the weak side (0.2 V), in order to minimize the air volume of the Sumi, the Tumi weak flag is set. The flag is turned on and the toumi strong flag is turned off. When the adjustment value is equal to or higher than the set value (4.8V) on the strong side, the toumi weak flag is turned off and the toumi strong flag is turned on in order to maximize the toumi air volume.
Then, when the adjustment value is between the set value on the weak side and the established value on the strong side, both flags are turned off so that the toumi air volume becomes a value corresponding to the adjustment value.
In addition, the toumi target value is set corresponding to the adjustment value. Note that the relationship between the adjustment value and the target value is in a direct proportional relationship, as in the case of the chaff opening.

Explaining the wet mode, as shown in FIG. 2 (e), the target value of the chaff opening is set to the maximum value (26 mm) on the opening side, and the target value of the toumi air volume is
The value is set to a value corresponding to the adjustment value by the potentiometer (S ₉ ) for adjusting the air volume of the toumi. Even in this wet mode, the adjustment value and the target value are set to have a direct proportional relationship, but the range of the settable target value is on the stronger side than the adjustment range in the check mode as a whole. The range is set to.

Next, the operation in the automatic mode will be described based on the flow chart shown in FIG.

First, it is determined whether or not the back switch (S ₆ ) is ON, and when it is OFF, the stock origin sensor (S ₀ ) is turned off.
It is determined whether or not N is set. The back switch
(S ₆ ) is ON, and the stock sensor (S ₀ ) is OFF
The processing in the case of is described later.

The back switch (S ₆ ) is OFF and the stock sensor
When (S ₀ ) is ON, it is determined whether the stock source sensor (S ₀ ) is ON for the first time, and when it is ON for the first time,
When it is determined that the reaping work has started, the current rotation speed detected by the engine rotation speed sensor (S ₇ ) is set to the reference rotation speed, and if it is not turned on for the first time, the reference rotation speed is Determine whether it is greater than the current speed,
If not, the reference speed is updated to the current speed.

Then, the current rotation speed is subtracted from the reference rotation speed to obtain a rotation speed down value, and the rotation speed down value is set to a set value (200 rpm).
Is set to)) or more.

When the rotation speed down value is less than the set value,
Based on the information of the grain culm type selection switch (S ₁₀ ), it is determined whether the treated grain culm is rice or wheat.

When the grain culm is rice, in order to correct the target value of the air flow of the toumi to a value corresponding to the vehicle speed detected by the vehicle speed sensor (S ₁ ), correction for the rice from the value of the detected vehicle speed is performed. Value map
The toumi correction value is set based on (f ₁ ) (see FIG. 3 (b)), and when the grain culm is wheat, the correction value map for wheat (f ₂ ) (see FIG. 3 ( The above-mentioned correction correction value is set based on (2) above).

Next, after the difference between the vehicle speed at the time of the previous detection and the current vehicle speed is calculated, when the vehicle speed is greatly reduced, the delay flag set to cause the chaff opening to be changed with a delay time is ON. Or not.

If the delay flag is ON, it is determined whether or not a set time has elapsed, and if the set time has elapsed, the delay flag is turned OFF, and then the chaff correction value is set to the chaff correction value based on the detected vehicle speed. Set based on the correction value map (g) (see Fig. 3 (c)).

When the delay flag is OFF, it is determined whether or not the deceleration is greater than the set value, and when the deceleration is greater than or equal to the set value, the delay flag is turned on and the deceleration is greater than or equal to the set value. If it is not deceleration, the chaff correction value is set to a value according to the detected vehicle speed.

However, when the rotation speed down value is equal to or more than the set value, both the toumi correction value and the chaff correction value are set to zero.

After setting the delay flag or the chaff correction value,
It is determined whether or not the elapsed time after the stock origin sensor (S ₀ ) is turned on has exceeded a set value (5 seconds). That is, it is made to determine whether or not the time required for the mowing work to stabilize has elapsed from the start of the mowing work.

When the elapsed time after the stock source sensor (S ₀ ) is turned on is less than the set value, the chaff stop flag and the toumi stop flag are maintained in order to maintain the chaff opening degree and the toumi air volume at the current values. Both are turned on to complete the processing in this automatic mode.

When the elapsed time after the stock origin sensor (S ₀ ) is turned on has exceeded the set value, both the chaff stop flag and the toumi stop flag are turned off, and then the grain culm type selection switch (S Based on the information of ₁₀ ), the value set by the potentiometer for adjusting the chaff opening (S ₈ ) corresponds to each of the case of rice and the case of wheat, and a preset map (h ₁ = for rice, h ₂ = for wheat) (see Fig. 3 (d)), and then add the adjusted value and the correction value according to the vehicle speed to obtain the chaff target. Set the values to the values for rice and wheat respectively.

Next, it is determined whether or not the chaff target value is less than the minimum value on the closing side, and if it is less than the minimum value, the minimum value is set. However, this minimum value is set so that rice is larger than wheat. By the way, this minimum value is set to 18 mm for rice and 14 mm for wheat.

After setting the chaff target value, the toumi target value is set by adding the adjustment value (see FIG. 3 (e)) by the potentiometer (S ₉ ) for adjusting the toumi air volume and the correction value by the vehicle speed. To do. However, when the toumi target value is less than a preset minimum value (850 rpm), it is set to the minimum value.

Explaining the processing when the back switch (S ₅ ) is ON or when the stock yuan sensor (S ₀ ) is OFF, when the stock yuan sensor (S ₀ ) is OFF It is determined whether or not the stock sensor (S ₀ ) is turned off for the first time,
When it is turned off for the first time, the stock sensor (S ₀ ) is turned on.
After storing the current number of rotations of the tomi at the time of changing from OFF to OFF as the stock source OFF number of rotations, it is determined whether it is rice or wheat based on the information of the grain culm type selection switch (S ₁₀ ).

If it is rice, the stock sensor (S ₀ ) is OF
It is determined whether the elapsed time after F, that is, the stock OFF time is less than the set value (10 seconds), and if it is less than the set value, the toumi target value is calculated from the stock OFF speed. It is set to a value obtained by subtracting the set rotation speed (200 rpm), and when the stock source OFF time is equal to or longer than the established value, the toumi target value is set to the set rotation speed (800 rpm).

Next, in order to set the target value of the chaff opening according to the stock-source OFF time, the stock-source OFF time is again set for a set time (set to 15 seconds, which is longer than in the case of the Tumi). If it is less than the set time, the chaff stop flag is turned on to complete the automatic mode processing, and if it is more than the set time, the chaff stop flag is turned off. Moreover, after setting the chaff target value to the minimum value (18 mm) on the closing side, the processing of this automatic mode is completed.

On the other hand, when the grain culm is barley, the stock origin OF is set without setting the target value of tomi according to the stock origin OFF time.
By setting the F rotation speed to the toumi target value, the rotation speed when the stock origin sensor (S ₀ ) is turned off, that is, the toumi air volume is maintained. However, the chaff opening is the same as in the case of rice when the stock origin sensor (S ₀ ) is OF.
After the F is set, the current opening is maintained until the set time (10 seconds) elapses, and then the stock source OFF time is less than the set time (10 seconds) in order to reach the minimum value (14 mm). If it is less than the set time, the chaff stop flag is turned on. If it is more than the set time, the chaff stop flag is turned off and the chaff target value is set to the minimum value. I am doing it.

In other words, when the grain culm is rice, as the grain culm is not supplied, the chaff opening is closed to a set value on the closing side corresponding to the sorting state with a small processing amount with a delay time. ,
In addition, when the cedar culm is wheat, the chaff opening is reduced with a delay time smaller than that of rice so that the treated amount is small. Close to the set value on the close side corresponding to the selected state of
The toumi air volume is maintained at the air volume at the time when the grain culm supply state was changed to the non-supply state.
