[Conventional technology]

The sorting control device of the threshing device of this type, the amount of the leaked material from the handling room is determined according to both the amount of grain culm supplied to the handling room and the amount of the second product returned to the handling room. Since it fluctuates, it is necessary to detect the amount of leaked waste based on both the amount of grain culm supplied and the amount of second reduction, and to automatically adjust the sorting state of the sorting device based on the detected amount of leaked waste. It is composed of.

However, the processed material corresponding to the time when the amount of grain culm supplied is leaked from the handling room after the first set time determined according to the operating characteristics of the threshing device, and is returned to the handling room. It is further after the second set time that is the predetermined time that the processed product corresponding to the second product leaks.

[Problems to be Solved by the Invention]

By the way, in the selection control device of the threshing device, the leakage processing material amount at the present time is detected from the grain culm supply amount before the first set time and the reduction amount before the second set time stored in the storage means. Is configured to
There were the following inconveniences.

That is, if the threshing clutch is disengaged during the work, the work will be interrupted while the processed material remains in the handling room or the sorting device. However, if the stored information in the storage means is continuously updated, The value of the amount of grain culm supplied before the first set time or the amount of reduction at the second set time corresponding to the processed material staying in the sorting device will change, and the threshing clutch is then turned on and operated. The state of sorting at the time of restarting the work by
There is a risk that the state immediately before the operation of disengaging the threshing clutch will not be supported, and at the time of resuming the work, the grain will be scattered outside the threshing device and the third loss will increase.

The present invention has been made in view of the above circumstances, and a first object thereof is to operate the threshing clutch once in the disengaged state and then in the engaged state again to restart the work.
The purpose is to enable the adjustment of the sorting state of the sorting apparatus to be restarted from the sorting state corresponding to the amount of leaked material at the time of the work interruption.

A second purpose is to provide a sensor or the like for directly detecting the amount of the second product returned from the sorting device to the handling room,
It is to be able to detect accurately.

[Means for Solving the Problems]

A first characteristic configuration of a threshing device selection control device according to the present invention is provided with a clutch operation state detecting means for detecting whether the threshing clutch is in an engaged state or a disengaged state,
The storage means is configured to stop updating the storage information based on the detection information of the clutch operation state detection means when the threshing clutch is in the disengaged state.

In addition to the first characteristic configuration described above, the second characteristic configuration is
The second reduction amount determination means is a multiplication value obtained by multiplying a value of the grain culm supply amount before the first setting time by a first setting value less than 1, or a subtraction value by subtracting the setting value, and the second setting. A value obtained by adding a multiplication value obtained by multiplying the value of the reduction amount before time by a second setting value less than 1 or a subtraction value obtained by subtracting the setting value is determined as the value of the reduction amount at the present time. The treated substance amount detecting means detects a value obtained by adding a value of the grain culm supply amount before the first set time and a value of the reduced amount before the second set time as the leaked substance amount. It is configured as follows.

[Operation] In the first characteristic configuration, the threshing clutch is detected by detecting the on / off state of the threshing clutch, and when the threshing clutch is in the disengaged state, the updating of the stored information in the storage unit is stopped. The stored information of the grain culm supply amount and the reduction amount corresponding to the time point when the operation is re-entered and restarted is not changed.

By the way, a part of the processed material that leaks from the handling room is to be returned as a second product, and the second product that has been returned to the handling room is temporarily reducing the corresponding amount of the processed product to be leaked. However, a part of it is repeatedly returned to the handling room.

Therefore, in the characteristic configuration according to claim 2, in addition to the configuration according to claim 1, the grain culm supply amount before the first set time stored in the storage means corresponds to the grain culm supply amount. The reduction amount before the second set time in which the reduction amount of the second product is obtained and a part of the leakage processing substance corresponding to the second substance is returned to the handling room again as the second substance Is calculated, and a value obtained by adding the calculated values is calculated as the return amount at the present time, and the value of the return amount before the second set time stored in the storage means and the value before the first set time are stored. The value obtained by adding the value of the amount of grain culm supplied is obtained as the amount of processed material leaked from the handling room.

〔The invention's effect〕

Therefore, according to the configuration of claim 1, when the threshing clutch is in the disengaged state, the update of the stored information in the storage means is stopped, so the threshing clutch is operated again to be in the engaged state and the work is restarted. Even if the threshing clutch is disengaged, the sorting state of the sorting device can be automatically adjusted in an appropriate manner based on the information corresponding to the amount of the leakage processing material at the time of the disengagement operation.

According to the configuration of claim 2, the second reduction amount is based on the grain culm supply amount detected by the supply amount detecting means, and in a state corresponding to the fluctuation of the detected grain culm supply amount. Since it can be determined by calculating, it is not necessary to provide a special device such as a sensor for detecting the amount of reduction of the second product, and while the simplification of the device configuration is achieved, the sorting state of the sorting device is
It is possible to automatically adjust to a sorting state corresponding to the actual amount of leaked material at the present time.

As a result, it has become possible to accurately control the occurrence of loss No. 3 when resuming work.

As shown in FIG. 1, a control device (55) using a microcomputer is provided, and the control device (55) displays a sorting state according to the amount (VOL) of the leaked substance from the handling room (A). A manually operated automatic switch (SW) for instructing whether or not to automatically adjust, a threshing switch (S ₀ ) which is turned on in association with the operation of engaging the threshing clutch (7), and the supply amount detecting sensor (S ₁ ), The chaff opening detection potentiometer (S ₂ ), the toumi air volume detection potentiometer (S ₃ ), and the chaff opening for manually setting the chaff opening when the automatic switch (SW) is in the OFF state.

Is connected to each of the condition setting potentiometers (S ₆ ) for making corrections depending on the processing conditions such as whether or not it is a wet culm.

That is, the threshing switch (S ₀ ) corresponds to the clutch operation state detecting means for detecting the on / off state of the threshing clutch (7).

In addition, in the figure, (56) is an automatic lamp for displaying whether or not the sorting state of the sorting device (B) is in the state of being automatically adjusted, and the automatic switch (SW) is turned on. It is designed to be linked and turned on.

Then, the control device (55) controls the automatic switch (S
W) is ON and the threshing switch (S ₀ ) is O
N and when the threshing clutch (7) is in the engaged state,
It is configured to control the electric motors (M ₁ ) and (M ₂ ) on the basis of preset information stored in advance and various input information to automatically adjust the sorting state of the sorting device (B). ing.

That is, using the control device (55), the leak 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 detection means (100). The sorting device (B) is arranged so that the larger the amount of processed material (VOL), the larger the amount of leaked processed material in the selected state.
Sorting state control means (101) for automatically adjusting the sorting state of
The second reduction amount determination means (102) for detecting the reduction amount (F) of the second product, and the grain culm supply amount (Q) detected by the supply amount detection sensor (S ₁ ) as the supply amount detection means. ) And a value corresponding to the set number of reduction amounts (F) detected by the second reduction amount determination means (102) are stored while being updated at every set time. Each of) is composed.

The adjustment of the sorting state of the sorting device (B) will be described. As the amount of harvested grain culm increases and the amount of grain culm introduced into the threshing device (2) increases, the feed chain (1
The thickness (D) of the grain culm layer conveyed in 2) becomes large, and the handling amount per unit time in the handling room (A) increases. As a result, the feed chain (1
The larger the thickness (D) of the grain culm layer conveyed in 2), the larger the amount (VOL) of the material leaked from the handling room (A),
It can be considered that the thickness (D) of the grain culm layer and the amount (VOL) of the leaked material from the handling room (A) correspond to each other.

Therefore, basically, based on the detection information of the supply amount detecting sensor (S ₁ ), a sorting state corresponding to a state in which the larger the grain culm supply amount (Q) is, the larger the leakage processing material amount (VOL) is. In other words, so that the opening of the chaff sheave (21) becomes large and the sorting air volume by the toumi (14) becomes large, both the toumi air volume and the chaff opening are automatically adjusted at the same time. I am doing it.

However, the amount of leaked material (VOL) from the handling room (A) is
Being influenced by not only the amount of grain culm supplied to the handling room (A) (Q) but also the amount of reduction (F) of the second product returned from the sorting device (B) to the handling room (A). From the above, a second reduction amount determination means (102) for detecting the reduction amount (F) of the second product is provided, and the leakage processing material amount (VOL) is detected at each set time by the grain culm supply amount. The detection is performed based on both (Q) and the reduction amount (F). That is, the sorting state of the sorting device (B) is changed to the handling room (A).
Therefore, the sorting state is set according to the actual amount of leaked material (VOL) that leaks from.

By the way, the grain culm located in 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 handling chamber (A), and the leakage process is performed on the grain culm. The material leaks from the handling room (A) because the first set time (tx) is determined according to the operating characteristics of the threshing device (2) from the time when the thickness (D) of the grain culm layer is detected. ) Later, the leakage treatment product of the second product corresponding to the leakage treatment product leaks from the handling room (A) only after the second set time (td) after a predetermined time. Become.

Therefore, the memory (103) as the storage means is configured into a so-called FIFO type by utilizing a memory (not shown) in the control device (55), and the stored data of the memory (103) is One cycle is set every time a reference time (set to 0.5 seconds) preset as the control loop setting time of the control device (55) elapses so that it is updated every set time.

Then, as will be described later in detail, the grain culm supply amount (Q) is calculated for each reference time based on the thickness (D) of the grain culm layer detected by the supply amount detecting sensor (S ₁ ). With
The grain culm supply amount (Q) calculated while erasing the oldest stored data is stored, and as described later, based on the grain culm supply amount (Q) before the first set time (tx), The current value of the return amount (F) is calculated, and the return amount (F) calculated while erasing the oldest stored data is stored in the memory (103).

Next, the operation of the control device (55) will be described in detail with reference to the flowchart shown in FIG.

As the control is started, first, it is determined whether or not the automatic switch (SW) is ON, and when the automatic switch (SW) is ON, the automatic lamp (56) is turned on. Then, it is displayed that the sorting state of the sorting device (B) is in the automatically adjusted state.

When the automatic switch (SW) is ON, it is determined whether the threshing switch (S ₀ ) is ON, that is, whether the threshing device (2) is in the operating state.

When the threshing switch (S ₀ ) is ON, during the reference time (0.5 seconds), the supply amount detecting sensor (S ₁ )
Based on the average value of the thickness (D) of the grain culm layer detected in
To calculate.

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

Then, as shown in FIG. 3 (a), the memory (10
While deleting the oldest data value of the grain culm supply amount (Q) stored in 3), each stored data is sequentially updated to the data after the reference time, and the calculated present grain culm supply amount (Q). )
Is stored as the latest value (Q (0)) in the memory (103).

Similarly, as shown in FIG. 3 (b), the value of the reduction amount (F) for each reference time stored in the memory (103) is set to the stored data while erasing the oldest data. Are sequentially updated to the data after the reference time.

After updating the data, as shown in equation (ii) below,
The value of the grain culm supply amount (Q (tx)) before the first set time (tx) stored in the memory (103) and the second set time (Q (tx)) stored in the memory (103) ( The value obtained by adding the value of the reduction amount (F (td)) before td) is calculated as the leaked substance amount (VOL).

VOL = Q (tx) + F (td) (ii) That is, the process for calculating the leaked processed material amount (VOL) based on the equation (ii) is the processed material amount detecting means (10).
It will correspond to 0).

In addition, the data update process, the threshing switch (S ₀ )
It is done only while it is ON. Therefore, as the threshing clutch (7) is next operated, the memory (103) can restart the control from the sorting state corresponding to the leakage processed material amount (VOL) immediately before the turning operation. Then, the state of storing and retaining the respective values of the grain culm supply amount (Q) and the reduction amount (F) until immediately before the cutting operation is continued.

After calculating the amount of leaked material (VOL), 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 detecting the chaff opening are used. Based on the value of the grain culm supply amount (Q (tx)) before the first set time (tx), the reduction rate (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 returned to the handling chamber (A) again after the second set time (td).

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

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 corresponding to the sorting state are set. Corresponding to each of the opening, it has been mapped in advance, the respective reduction rate values from the respective detection values by the toumi air flow detection potentiometer (S ₂ ) and the chaff opening detection potentiometer (S ₃ ) , Is read out from the reduction rate calculation map.

Next, the values of the reduction rates (K ₂ ) and (K ₄ ) calculated with reference to the reduction rate calculation map, and the grain culm supply amount (Q (tx) before the first set time (tx). ) And the reduction amount (F (td)) before the second set time (td), the value of the reduction amount (F (0)) at the present time is calculated from the following equation (iii). And update that value.

F (0) = K ₂ · Q (tx) + k ₄ · F (td) (iii) That is, the value of the reduction amount (F (0)) at the present time is calculated based on this equation (iii). The process corresponds to the second reduction amount determination means (102). Then, as is clear from the above formula (iii), 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 ( The reduction rate (K ₄ ) by which F) is multiplied corresponds to the second set value less than 1.

Then, based on the calculated value of the leakage processed material amount (VOL) and the setting value by 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,
In advance, a map is made in a state corresponding to the value of the amount of leaked material (VOL) and the setting value by the condition setting potentiometer (S ₆ ) and stored in the control device (55), and its target is set. The target value is read from the map for setting and set.

On the other hand, when the threshing auto switch (SW) is ON and the threshing switch (S ₀ ) is OFF, the threshing switch (S ₀ ) then changes from OFF to ON and the work is restarted. In this case, the stored data in the memory (103) is updated and the amount of leaked material (V) is increased so that the work is restarted from the sorting state immediately before the threshing switch (S ₀ ) is changed from ON to OFF.
The calculation is made to maintain a state in which the calculation of the OL) and the updating of the target values of the toumi air volume and the chaff opening based on the leaked material amount (VOL) are stopped.

On the other hand, when the automatic switch (SW) is OFF, the automatic lamp (56) is turned off and the target values of the toumi air volume and the chaff opening are adjusted so that the sorting state is manually adjusted. Is set to a set value manually set by each of the chaff opening adjustment potentiometer (S ₄ ) and the toumi air volume adjustment potentiometer (S ₅ ).

Then, after setting each of the target value of the toumi air volume and the chaff opening, regardless of whether it is manual setting or automatic adjustment, the chaff opening detection potentiometer (S ₂ ) and the toumi air volume Motor operation processing for operating both the selection state adjusting motors (M ₁ ) and (M ₂ ) so that the detection values of the detection potentiometer (S ₃ ) become the respective set target values. Will be done.

That is, the target values of the toumi air volume and the chaff opening are set according to both the leakage treated substances (VOL), and both the sorting state adjusting motors (M ₁ ) and (M ₂ ) are operated. The motor operation processing to be performed corresponds to the selection state control means (101).

However, although not described in detail, since the toumi air volume is configured to be changed and adjusted by the split pulley type transmission (42), when the threshing clutch (7) is in the disengaged state, the toumi air volume is The structure is not adjustable. Thus, in the motor operation process, the threshing switch (S ₀₎ is to determine whether or not the ON, when said threshing switch (S ₀₎ is not ON, the winnowing fan airflow for adjusting motor (M ₂ ) will maintain the stopped state at the current operating position.

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

That is, each time the reference time as the set time elapses, the plurality of grain culm supply amounts (Q) and reduction amounts (F) for each reference time are updated while being stored and stored, Threshing supply amount (Q) before 1 set time (tx),
Based on the reduction amount (F) before the second set time (td), the leaked material amount (VOL) at the present time is calculated, and the sorting state corresponding to the calculated leaked material amount (VOL). Thus, the control loop goes around while automatically adjusting the toumi air volume and the chaff opening.

[Another embodiment]

In the above embodiment, the threshing supply amount (Q) before the first set time (tx) is multiplied by the reduction rate (K ₂ ) less than 1 and the reduction amount (F) before the second set time (td). A reduction rate of less than 1 (K ₄ )
An example is shown in which the value obtained by adding the value obtained by multiplying by is calculated as the reduction amount at the present time. For example, instead of multiplying each reduction rate (K ₂ ), (K ₄ ), the set value May be subtracted.

Further, in the above embodiment, the grain culm supply amount (Q) is set to the handling room (A).
The case where the detection is performed based on the thickness (D) of the grain culm layer supplied to the above is illustrated. However, as the vehicle speed of the combine increases, the amount of cut grain culm per unit time increases, and the grain culm supply amount ( By utilizing the fact that Q) is proportional to the vehicle speed, for example, the vehicle speed is detected based on the shift output rotational speed of the traveling transmission (9), and the grain is indirectly determined based on the detected vehicle speed. The culm supply amount (Q) may be detected, and the specific configuration of the supply amount detecting means can be variously changed.

Further, in the above-mentioned embodiment, the case where both the toumi air volume and the chaff opening degree are adjusted to adjust the sorting state of the sorting apparatus (B) is illustrated, but either the toumi air volume or the chaff opening degree is adjusted. Only one of them may be adjusted.

Further, in the above embodiment, the case where the split pulley type speed change device (42) is used to change the rotational speed of the toumi (14) to adjust the sorting air volume is exemplified. (14) may be driven by a variable speed device such as an electric motor, and a specific configuration for adjusting the sorting air volume and a specific configuration for adjusting the opening of the chaff sheave (21). The specific configuration for adjusting the selection state of the device (B) can be changed in various ways.
