Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a sorting device for sorting a processed material from a handling room so as to be adjustable in a sorting state according to the processed material amount, and to detect the processed material amount. Based on detection information of the processed product amount detecting means and the processed product amount detecting means, an actuator for adjusting the selection state of the selection device is automatically set so that the larger the processed product amount is, the more the selected state corresponds to the larger processed product amount. The present invention relates to a combine sorting control device provided with control means for operating the combine.

[Conventional technology]

In order to make the sorting state of the sorting device appropriate, it is necessary to keep the amount of processed material in an appropriate range. Therefore,
At the start of the reaping work, the sorting device keeps the sorting state in a state where the amount of processed material is small until the amount of processed material reaches a predetermined amount,
After the processed material amount reaches a predetermined amount, it is desirable to adjust the sorting state of the sorting device based on the detection information of the processed material amount detecting means.

However, since it is difficult to directly detect the processed amount, for example, a thickness detection sensor that detects the thickness of the grain culm layer conveyed by the feed chain is provided, and the processed amount is detected based on the detection information of the sensor. It is supposed to do.

Therefore, conventionally, after a lapse of a predetermined time from the start of the mowing work, it is assumed that the amount of processed material has reached a predetermined amount, and control is started to adjust the sorting state of the sorting device based on the detection information of the processed material amount detecting means.

[Problems to be Solved by the Invention]

In the above-mentioned conventional technique, there is a possibility that a problem may occur in the selection at the start of the mowing work.

For example, when the vehicle speed is slow, the distance traveled from the start of the mowing operation to the lapse of a predetermined time is short, and therefore the amount of cut culm after the lapse of the predetermined time, that is, the processed material amount is small.
As a result, there arises a problem such that straw waste is mixed into the grain and is collected in the first mouth.

On the contrary, when the vehicle speed is high, the traveling distance from the start of the mowing operation to the elapse of a predetermined time becomes long, and therefore the amount of cut culm after the lapse of the predetermined time, that is, the processed material amount becomes large. As a result, there is a possibility that the grain that has not been sorted and collected by the sorting device may be discharged to the outside of the machine along with the straw waste, resulting in a third loss.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks and obtain a combine selection control device capable of performing stable selection at the time of starting a mowing operation regardless of the vehicle speed.

[Means for solving the problem]

In order to achieve this object, the characteristic configuration of the combine selection control device according to the present invention is a working state detecting means for detecting whether or not the combine is in the cutting work state, and a distance detecting means for detecting the traveling distance of the combine. Is provided, the control means detects the working state detecting means is in a mowing work state, and then the processing is performed while the traveling distance of the combine detected by the distance detecting means is smaller than a set distance. That is, the sorting state of the sorting device is adjusted so that a set sorting state corresponding to a state in which the physical quantity is small is obtained.

[Work]

The amount of harvested culm after the start of harvesting is considered to be approximately proportional to the distance traveled. Therefore, the distance at which the amount of cut culm, that is, the amount of processed material reaches a predetermined amount suitable for selection is set as the set distance.

In other words, after the combine has traveled the set distance, the amount of processed material has reached the predetermined amount that is suitable for sorting, so the sorting device performs sorting until the combine travels the set distance after the harvesting operation state is detected. The state is adjusted to a state in which the amount of processed material is small, and after the combine has traveled the set distance, it is adjusted so as to be in a sorted state according to the amount of processed material.

〔The invention's effect〕

Therefore, until the amount of processed product reaches a predetermined amount suitable for sorting, the processed product amount is maintained in a sorting state corresponding to a small state,
Since the control for adjusting the sorting state is started based on the detection information of the processed material amount detection means when the processed material amount reaches a predetermined amount suitable for sorting, for example, the processed material amount is reached when a predetermined time has elapsed from the start of the cutting operation. When the work speed is slow or fast, straw dust is collected at the first mouth depending on whether the vehicle speed is slow or fast, as in the prior art, in which adjustment control of the sorting state is started based on the detected amount of processed material as it reaches a predetermined amount suitable for sorting. Thus, it is possible to obtain a combine selection control device with excellent selection performance that is less likely to cause problems such as a third loss.

And the operation arm (49) and the electric motor (M ₂ ) drive the forward and reverse rotations of the screw shaft (50) to engage the top member (51).
Are linked by a release wire (52), and the first cam forming member (47) is rotatably operated by the air volume adjusting electric motor (M ₂ ), whereby the toumi (14)

In FIG. 13, (43) is a transmission belt for transmitting the output of the engine (E) to the input pulley (41), (44) is a tension pulley, and (S ₃ ) is a speed change state, that is, the sorting air volume is This is a potentiometer for detecting a quantity of air flow of toumi that detects a position change of a top member (51), and a free end portion of an operation lever (53) of the potentiometer is connected to the top member (51).

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, a control structure for controlling the sorting state of the sorting device (B) by operating the actuators (M ₁ ) and (M ₂ ) will be described.

As shown in FIG. 1, a control unit (H) utilizing a microcomputer is provided, and the threshing switch (S _W ) which is turned on in association with the operation of engaging the threshing clutch (7) in the control unit (H), A stock sensor (S _O ), the thickness detection sensor (S ₁ ), the chaff opening detection potentiometer (S ₂ ), the toumi air volume detection potentiometer (S ₃ ), the vehicle speed sensor (S ₄ ), and Amount of treated material (VO

Then, the control device (H) controls the actuators (M ₁ ) and (M ₂ ) on the basis of preset information stored in advance and various input information, and the sorting state of the sorting device (B). Is configured to adjust.

That is, by using the control device (H), based on the detection information of the thickness detecting sensor (S ₁ ), the amount of processed material (VO
The detection means of the control means (100) and the vehicle speed sensor (S ₄ ) that automatically adjust the sorting state of the sorting device (B) so that the larger L becomes, the larger the sorting amount corresponding to the amount of processed material (VOL) becomes. A traveling distance integrating means (101) for integrating the traveling distance of the combine based on the information, a second reduction amount detecting means (102) for detecting the reduction amount (F) of the second product, and a first set time (t).
_X ) the first storage means (103) for storing the value of the grain culm supply amount (Q) detected before, and the reduction amount (F) detected before the second set time (t _D ). Each of the second storage means (104) for storing the value is configured.

That is, the vehicle speed sensor (S ₄ ) and the traveling distance integrating means (101) are used to constitute distance detecting means (S ₄ , 101) for detecting the traveling distance of the combine.

The adjustment of the sorting state of the sorting device (B) will be described. As the amount of cut culm and the amount of grain culm introduced into the threshing device (2) increase, the feed chain (12) conveys the grains. The thickness (D) of the grain culm layer to be processed 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 by the feed chain (12), the greater the amount of processed material (VOL) from the handling chamber (A), and the thickness of the grain culm layer ( It can be considered that D) corresponds to the amount (VOL) of processed material from the handling room (A).

Therefore, basically, on the basis of the detection information of the thickness detecting sensor (S ₁ ), the larger the amount of processed material (VOL) is, the larger the processed material amount (VOL) becomes. Both the toumi air volume and the chaff opening are automatically adjusted at the same time so that the opening degree of the chaff sheave (21) becomes large and the sorting air quantity by the toumi (14) becomes large.

However, regardless of the detection information of the thickness detection sensor (S ₁ ) from the start of mowing when the stock sensor (S ₀ ) changes from the OFF state to the ON state until the combine travels the set distance, the processed material amount (VOL) is The toumi air volume and the chaff opening are adjusted to be small so that the set selection state corresponding to the smaller state is achieved.

The amount (VOL) of processed material from the handling room (A) is not limited to the amount (Q) of grain culm supplied to the handling room (A), but from the sorting device (B) to the handling room (A). The second reduction amount detecting means (102) for detecting the reduction amount (F) of the second product is provided to be affected by the reduction amount (F) of the second product to be reduced. ) Is detected based on both the grain culm supply amount (Q) and the reduction amount (F) detected at each set time. That is, the sorting state of the sorting device (B) is set according to the actual amount of processed material (VOL) leaking from the handling room (A).

By the way, the grain culm located at the position where the thickness (D) of the grain culm layer is detected by the thickness detecting sensor (S ₁ ) is treated in the handling chamber (A), and the processed matter for it is Leakage from the handling room (A) occurs after the first set time (t _X ) determined according to the operating characteristics of the threshing device (2) from the detection operation time of the thickness (D) of the grain culm layer. 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 (t _d ) after a predetermined time. .

Therefore, a first memory (103) as a first storage means for storing the grain culm supply amount (Q) up to the first set time (t _X ) and up to the second set time (t _d ). The second memory (104) as a second storage means for storing the reduction amount (F) of the above is configured by a so-called FIFO type using a memory (not shown) in the control device (H). At the same time, the control loop of the control device (H) is preset as the set time so that the stored data of each of the first memory (103) and the second memory (104) is updated every set time. Every time the reference time (set to 0.5 seconds) elapses,
It is designed to go around once.

Then, as will be described later in detail, the grain culm supply amount (Q) is calculated based on the grain culm layer thickness (D) detected by the thickness detecting sensor (S ₁ ) at each reference time. ,
The grain culm supply amount (Q) calculated while deleting the oldest stored data is stored in the first memory (103), and, as described later, the grain culm supply before the first set time (t _X ). A current value of the reduction amount (F) is calculated based on the amount (Q), and the reduction amount (F) calculated while erasing the oldest stored data is stored in the second memory (104). I am doing it.

Next, the operation of the control device (H) will be described based on the flowcharts shown in FIGS.

As the control is activated, the threshing switch (S
It is determined whether w) is ON, that is, whether the threshing device (2) is in the operating state.

And when the threshing switch (Sw) is ON,
Check the flag (F). The flag (F) is set to "0" at the time of starting.

When the flag (F) is “0”, the amount of processed material is determined based on the detection information of the thickness detection sensor (S ₁ ) except when the stock sensor (S ₀ ) changes from OFF to ON. (VO
As L) increases, the normal control for adjusting the toumi air volume and chaff opening is performed so that the sorted state corresponds to the larger volume (VOL).

When the stock origin sensor (S ₀ ) changes from OFF to ON, the flag (F) is set to "1" and the toumi air volume and the chaff opening are adjusted to be small.

During the flag (F) is "1", integrates the travel distance (Y) based on detection information of the vehicle speed sensor (S _4). When the travel distance (Y) reaches a set distance (Y _s) flag (F) is reset to "0". That is, the target values of the toumi air volume and the chaff opening are set to a small value from the start of mowing until the combine travels the set distance (Y _s ).

When the description of the normal control is added, as shown in FIG. 2B, the grain culm supply amount (Q) at the present time is calculated from the following formula (i) based on the average value of the thickness (D).

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

Then, as shown in FIG. 3 (a), the stored data in the first memory (103) is deleted while erasing the oldest value.
Each stored data is sequentially updated to the data after the reference time, and the obtained value of the present grain culm supply amount (Q) is used as the first value.
The latest value (Q (0)) of the memory (103) is stored.

Similarly, as shown in FIG. 3 (b), the value of the reduction amount (F) stored in the second memory (104) for each reference time is changed while deleting the oldest data. The stored data is sequentially updated to the data after the reference time.

After updating the data, as shown in the following formula (ii), the first memory stored in the first memory (103) is stored.
The value of the grain culm supply amount (Q (t _X )) before the set time (t _X ) and the reduction amount (F) before the second set time (t _d ) stored in the second memory (104). The value obtained by adding the value of (t _d )) is calculated as the processed material amount (VOL).

VOL = Q (t _X ) + F (t _d ) ... (ii) After calculating the amount (VOL) of the processed material, the potentiometer (S ₃ ) for detecting the toumi air volume and the potentiometer (S ₂ for adjusting the chaff opening) ) Corresponding to the value of the grain culm supply amount (Q (t _X )) before the first set time (t _X ), based on the current Toumi air volume and the chaff opening detected in). The reduction rate (K ₂ ) of the second product reduced to (A), and the second product and a part of the second product are returned to the handling chamber (A) again after the second set time (t _d ). Calculate the reduction ratio (K ₄ ) of the second product.

However, a part of the processed product from the handling room (A) is reduced to the handling room (A) as a second product, and a part of the processed product corresponding to the reduced second product is , 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 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 volume detection potentiometer (S ₃ ) and the chaff opening detection potentiometer (S ₂ ) , 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 (t) before the first set time (t _X ). _X )) and the reduction amount (F (t _d )) before the second set time (t _d ), the reduction amount (F (0)) at the present time is calculated from the following formula (iii).
The value of is calculated and the value is updated.

(F (0)) = K ₂ · Q (t _X ) + K ₄ · F (t _d ) …… (ii
i) That is, the process of calculating the value of the reduction amount (F (0)) at the present time based on the equation (iii) corresponds to the second reduction amount detecting means (102). And
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 (F) The reduction rate (K ₄ ) to be multiplied by corresponds to the second set value of less than 1.

Then, the value of the leaked material amount (VOL) calculated above,
Based on the setting value by the condition setting potentiometer (S ₅ ), 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 processed material amount (VOL) and the set value by the condition setting potentiometer (S ₅ ) and stored in the control device (H),
The target value is read and set from the map for setting the target.

Then, after setting each of the target value of the toumi air volume and the chaff opening, each of the detection values by the chaff opening detection potentiometer (S ₂ ) and the toumi air volume detection potentiometer (S ₃ ), A motor operation process for operating both the selection state adjusting motors (M ₁ ) and (M ₂ ) is performed so that each of the set target values is achieved.

That is, a motor operation for operating both the selection state adjusting motors (M ₁ ) and (M ₂ ) by setting the target values of the toumi air volume and the chaff opening according to the processed material amount (VOL). The processing corresponds to the control means (100).

However, although not described in detail, since the toumi air volume 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 toumi 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 (Sw) is turned on, and when the threshing switch (Sw) is not turned on, the motor for adjusting the thyme air volume (M _{In 2} ), the stopped state will be maintained 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 threshing switch (Sw) is determined. Each process of is repeated.

In the above-described embodiment, the processed product amount is detected based on both the grain culm supply amount and the reduction amount, but the selection state may be adjusted by using the grain culm supply amount as it is as the processed product amount.

In the above-mentioned embodiment, the stock element sensor provided in the harvesting section of the combine is used as the working state detecting means (S ₀ ), but the specific configuration of each section may be changed in various ways, such as also being used as the processed material amount detecting means (S ₁ ).
