That is, the actuator (M) for adjusting the sorting state of the sorting device (B) is an electric motor (M ₁ ) for adjusting the spacing of the chaff sheave (21) and an electric motor for adjusting the sorting air volume of the toumi (14). (M ₂ ). Next, this actuator (M
A control configuration for activating ₁ ) and (M ₂ ) to control the sorting state of the sorting device (B) will be described.

As shown in FIG. 1, a control device (H) using a microcomputer is provided, and the control device (H) has a selection switch (Sw) for selecting an automatic mode and a manual mode, and the threshing clutch (7) is turned on. Threshing switch (S

A switch for adjusting the chaff opening for manually setting the chaff opening (S ₄ ), a switch for adjusting the tofu air volume for manually setting the toumi air volume when the selection switch (Sw) is in the manual mode state. (S ₅ ), and the target selection state corresponding to the leaked material amount (VOL) in the automatic mode, for example, processing conditions such as rice or wheat, or wet culm. Each of the condition setting potentiometers (S ₆ ) for correction according to the above is connected. In addition, (P) in the figure is a display unit for displaying the amount of leaked material (VOL).

Then, the control device (H), based on the information preset and stored and various input information, the actuator (M
₁ ) and (M ₂ ) are controlled to adjust the selection state of the sorting device (B).

That is, using the control device (H), the leakage amount is detected based on the detection information of the treatment amount detection means (100) for detecting the leakage treatment amount (VOL) and the treatment amount output means (100). The control means (101) for automatic long cut, which automatically adjusts the sorting state of the sorting device (B), so that the larger the volume of treated material (VOL) is, the more the sorted state corresponds to the amount of leaked processed material, the manual mode Instructing to start and stop adjustment and adjustment direction of the sorting state of the sorting device (B) based on the information from the chaff opening adjustment switch (S ₄ ) and the toumi air volume adjustment switch (S ₅ ) in the state Means (106), control means (102) for manual adjustment for automatically operating the actuators (M ₁ ), (M ₂ ) based on the information of the instructing means (106), the sorting state adjusted in the manual mode. Storage means (104) that stores the target selection state, from automatic mode to manual mode Said actuator to operate the target selection state stored in the destination storage means (104) ze with the be replaced (M _1), (M ₂₎ auxiliary control means for operating (103), said selection switch (Sw ) Selecting means (105) for entrusting the automatic mode and the manual mode based on the information from the above), the second reduction amount detecting means (107) for detecting the reduction amount (F) of the second product, the first set time (t) _x ) A first storage means (10) for storing the value of the grain culm supply amount (Q) detected previously.
8) and second storage means (109) for storing the value of the reduction amount (F) detected before the second set time (T _d ) respectively.

Explaining the adjustment of the sorting state of the sorting device (B) in the automatic mode, as the amount of harvested grain culm increases and the amount of grain culm introduced into the grain culm device (2) increases, the feed chain (12 In this case, the thickness (D) of the grain culm layer transported in () becomes large, and the handling amount per unit time in the handling room (A) increases. As a result, the larger the thickness (D) of the grain culm layer conveyed in the feed chain (12), the greater the amount of the leakage treated material (VOL) from the handling room (A), and the thickness of the grain culm layer. (D) and the amount of leaked material (VO) from the handling room (A)
L) can be regarded as corresponding.

Therefore, basically, based on the detection information of the supply amount detecting sensor (S ₁ ), the rice cracker state corresponding to the state that the larger the grain culm supply amount (Q) is, the louder the leaked processed material amount (VOL) is. In other words, that is, so that the opening degree of the chaff sheave (21) becomes large and the sorting air volume by the toumi (14) becomes large,
It is configured to automatically adjust toumi air volume and good news about chaff opening.

However, the amount of processed material leaked from the handling room (A) (VOL) is not only the amount of grain culm supplied to the handling room (A) (Q) but also the sorting device.
Reduction amount (F) of the second product reduced from (B) to the handling room (A)
The second reduction amount detection means (107) for detecting the reduction amount (F) of the second substance from the influence of the above is provided, and the leaked substance amount (VOL) is detected at every set time. Grain culm supply
The detection is made based on both (Q) and the reduction amount (F). In other words, the sorting state of the sorting device (B) depends on the actual amount of leaked material (V) leaking from the handling room (A).
(OL) It is designed to be in a selected state according to.

By the way, the grain culm at the position where the thickness (D) of the grain culm layer is detected by the supply amount detecting sensor (S ₁ ) is treated in the treatment room (A) and leaked to it. The processed material is the handling room
What leaks from (A) is after the first set time (t _x ) to wear according to the operating characteristics of the threshing device (2) from the time when the thickness (D) of the grain culm layer is detected. The leakage of the second processed material of the leakage processing, which corresponds to the leakage processing, leaks from the handling room (A) after the second set time (t _d ) after a further predetermined time.

Therefore, the grain culm supply amount before the first set time (T _x ).
First memory (108) as first storage means for storing (Q)
And a second memory (109) as a second storage means for storing the reduction (F) up to the second set time (t _d ) before, a memory (not shown) in the control device (H). ) Is used to configure the so-called FIFO type, and the first memory
(108) and the second memory (109) A reference time (0.5 second is set in advance by the control loop of the control device (H) is set as the set time so that the respective stored data are updated at each set time. Each time it passes (set), one cycle is made.

And, as will be described later in detail, for each reference time, the thickness of the grain culm layer detected by the supply amount detecting sensor (S ₁ ).
The grain culm supply amount (Q) is calculated based on (D), and the grain culm supply amount (Q) calculated while erasing the oldest stored data is stored in the first memory (108), and described later. Like
Based on the grain culm supply amount (Q) before the first set time (t _x ), the current value of the reduction amount (F) is calculated, and the reduction amount calculated while erasing the oldest stored data is calculated. (F) is stored in the second memory (109).

Next, based on the flowchart shown in FIG.
The operation of the control device (H) will be described.

When the control is started, the standard selection state set in advance is stored in the storage means (104) as the target selection state in the manual mode.

In manual mode, switch for adjusting chaff opening (S ₄ )
The actuators (M ₁ ) and (M ₂ ) are driven based on the information from the toumi air volume adjustment switch (S ₅ ).

In the case of the automatic mode, it is determined whether or not the threshing switch (So) is ON, that is, whether or not the shredding threshing device (2) is in an operating state.

When the threshing switch (So) is ON, the thickness (D) of the grain culm layer detected by the supply amount detecting sensor (S ₁ ) during the reference time (0.5 seconds). Based on the average value of), the present supply of grain culm (Q) is calculated from the following formula (i).

Q = K ₁ · D (i) where K ₁ is a preset constant.

Then, as shown in FIG. 3 (a), the first memory (10
While deleting the oldest value of the stored data of 8), each stored data is sequentially updated to the data after the reference time, and the value of the present grain culm supply amount (Q) obtained is stored in the first memory. (1
It is stored as the latest value (Q (O)) of 08).

Similarly, as shown in FIG. 3B, the second memory
The value of the reduction amount (F) for each reference time stored in (109) is sequentially updated to the data after the reference time while erasing the oldest data.

After updating the data, as shown in equation (ii) below,
The value of the grain culm supply amount (Q (t _x )) before the first set time (t _x ) stored in the first memory (108) and the value stored in the second memory (109) The value obtained by adding the value of the reduction amount (F (t _d )) before the second set time (t _d ) that is
Calculate as L).

(VOL) = Q (t _x ) + F (t _d ) (ii) In other words, based on this equation (ii), the amount of leaked material (V
The processing for calculating OL) corresponds to the processing amount detecting means (100).

In the data updating process, the threshing switch (So) is turned off.
It is designed to be performed only during N periods. Therefore,
Each of the first memory (108) and the second memory (109) is provided with the threshing clutch (7) as the threshing clutch (7) is next operated.
In order to restart control from the sorting state corresponding to the above, the grain culm supply amount (Q) and the maize chrysanthemum reduction amount up to immediately before the cutting operation
The state in which each value of (F) is stored is retained.

After calculating the amount of leaked material (VOL), based on the current toumi air volume and chaff opening detected by the potentiometer (S ₂ ) for detecting the toumi air volume and the potentiometer (S ₃ ) for adjusting the chaff opening. Then, in accordance with the value of the grain culm supply amount (Q (t _x )) before the first set time (t _x ), the reduction ratio (K ₂ of the second product returned to the handling room (A) ) And a reduction rate (K ₄ ) of a second product in which a part of the second product is reduced to the handling chamber (A) again after the second set time (t _x ).

However, a part of the leaked material from the handling room (A)
It will be reduced to (A) as a second product, and part of the leaked material corresponding to the reduced second product will be returned to the handling room (A) three times. .

Therefore, the reduction rates (K ₂ ) and (K ₄ ) are both less than 1. Further, since the value can be regarded as a substantially constant value corresponding to the sorting state of the sorting device (B), as shown in FIG. 4, the toumi air volume and chaff opening corresponding to the sorting state are Corresponding to each, it is mapped in advance, the value of each reduction rate corresponding from each detection value by the potentiometer for detecting the air volume of the toumi (S ₂ ) and the potentiometer for detecting the chaff opening (S ₃ ), the reduction rate. The map is read from the calculation map.

Next, the value of the reduction rate (K ₂ ), (K ₄ ) calculated with reference to the reduction rate calculation map, and the grain culm supply amount (Q (t) before the first set time (t _x ). the value of _x)), (based on the t _d) the reduction amount of the front (F (t _d), the reduction amount (F (0 at the current time from (iii) below equation) the second set time value of) Is calculated and the value is updated.

(F (0) ＝ (K ₂ ) ・ Q (t _x ) ＋ (K ₄ ) ・ (F (t _d ) …… (iii) In other words, based on this equation (iii), the reduction amount (F The process of calculating the value of (0) corresponds to the second reduction amount detecting means (107), and the above (ii)
As is clear from the equation i), the reduction rate (K ₂ ) by which the grain culm supply amount (Q) is multiplied corresponds to the first set value of less than 1, and the reduction amount (F) is multiplied by Second with a rate (K ₄ ) less than 1
It corresponds to the set value.

Then, based on the value of the leaked processed material amount (VOL) and the setting value of the condition setting potentiometer (S ₆ ), the target values of the toumi air volume and the chaff opening are calculated.

However, as shown in FIG. 5, the respective target values of the toumi air volume and the chaff opening degree are the same as in the calculation of the reduction rate,
Preliminarily, a map is made in a state corresponding to the value of the leaked material amount (VOL) and the setting value by the condition setting potentiometer (S ₆ ), and is stored in the control device (H), and its target is set. The target value is read from the map for setting and set.

Then, after setting each of the target value of the toumi air volume and the chaff opening, the chaff opening detection potentiometer (S ₂ ) and the toumi air volume detection potentiometer (S
_Each of the detection values by _3), so as to be each of the set target value, both motors (M ₁ ) for the sorting state adjustment,
The motor operation processing device for operating (M ₂ ) will be performed.

That is, the target values of the toumi air volume and the chaff opening are set in accordance with the leakage processed material amount (VOL), and both the motors (M ₁ ) and (M ₂ ) for adjusting the sorting state are operated. The motor operation processing device corresponds to the control means (101) for the automatic adjustment.

However, although not described in detail, since the air volume of the toumi is configured to be changed and adjusted by the split pulley type changing device (42), when the threshing clutch (7) is in the disengaged state, The structure does not come by adjusting the air volume. Therefore, in the motor operation process, it is determined whether or not the threshing switch (So) is ON, and the motor (M ₂ ) for which the threshing switch (So) is not ON is stopped at the current operation position. The condition will be maintained.

After performing the motor operation processing, it is determined whether or not a preset reference time has elapsed, and as the reference time elapses, the operation state of the selection switch (Sw) is determined. Each process will be repeated.

That is, every time the time as the set time elapses, the first setting is performed while updating while maintaining a plurality of storages of the grain culm supply amount (Q) and the reduction amount (F) for each reference time. Grain culm supply amount (Q) before time (t _x ) and the second set time (t _d )
Calculate the current amount of leaked material (VOL) based on the previous reduction amount (F), and calculate the calculated amount of leaked material.
The control loop goes around while automatically adjusting the toumi air volume and the chaff opening so that the sorting state corresponding to (VOL) is achieved.

Next, a case will be described in which the operation state of the zara selection switch (Sw) is switched from the automatic mode to the manual mode.
In this case, first, it is determined whether or not the sorting state at that time matches the target sorting band in the manual mode, and if they do not match, the actuator (M ₁ ) so that they match,
Drive and operate (M ₂ ).

That is, the sorting state of the sorting device (B) is stored in the storage means (104).
After that, it will be switched to the manual mode.
