Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method in which a sorting device for sorting out leaked waste from a handling chamber of a threshing device is provided in a sorting state that can be freely adjusted according to the amount of processing. , a grain culm supply detection means for detecting the presence or absence of grain culm supply to the threshing device, and a vehicle speed detection means for detecting the traveling speed of the machine body, and the grain culm supply detection means is in a grain culm supply state. is detected, the control is performed based on the detection information of the vehicle speed detection means so that the sorting state corresponds to a state in which the processing amount increases as the vehicle speed increases, and the grain culm supply detection means A sorting combine harvester equipped with sorting state control means for controlling to maintain a preset sorting state corresponding to a state in which a preset throughput is small when it is detected that the grain culm is not being supplied. Regarding a control device.

[Conventional technology]

The sorting control device of this type of combine harvester mentioned above is adapted to the reaping speed, that is, the traveling speed, because the faster the vehicle speed, the greater the amount of grain culm introduced into the threshing device, that is, the amount of grain to be processed. This makes it possible to automatically adjust the sorting state of the sorting device.

By the way, the reaping work in a combine harvester is carried out in a work style in which the reaping work is repeatedly interrupted as the harvester travels through one working process and the reaping work is redirected to the next working process.
Since no reaping work is performed during turning, the throughput in the threshing device decreases, and the vehicle speed and throughput do not correspond. Therefore, the presence or absence of grain culm supply to the thresher is detected and If there is no such setting, a preset selection state corresponding to a state in which the amount of processing is small is maintained.

[Problem that the invention seeks to solve]

By the way, when reaping a grain culm that has been planted to the edge of the ridge, the reaping work is performed by repeatedly moving forward and backward, but since no reaping work is performed when reversing, the throughput is reduced. This will be less than during normal work.

However, in the above conventional configuration, while the grain culm supply detection means is detecting grain culm supply, the sorting state is controlled according to the vehicle speed, so the amount of processing is reduced when the aircraft retreats. However, if the grain culm supply detection means is in a state of detecting grain culm supply to the threshing device, there is a risk that the control will be controlled to a sorting state that corresponds to a state where the throughput is large depending on the vehicle speed. .

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to prevent the sorting device from being controlled to a sorting state corresponding to a large throughput when the aircraft is retreating.

[Means for solving problems]

The characteristic configuration of the combine harvester sorting control device according to the present invention is as follows:
A backward detection means is provided for detecting whether the machine body is in a backward state, and the sorting state control means detects that the backward detection means is in a backward state, and the grain culm supply detection means is When it is detected that the grain culm is being supplied, the control operation is stopped, and its operation and effects are as follows.

[For production]

When the aircraft is switched from the forward state to the backward state, it will be switched to the reverse state after decelerating and stopping, so when the aircraft is switched to the backward state, the processing amount will be adjusted to a sorting state that corresponds to a small state. This means that it has been done.

In other words, when the aircraft is in the backward state and the grain culm supply detection means detects that the grain culm supply state is present,
By stopping the control operation of the sorting state control means, it is possible to maintain a sorting state that corresponds to a small throughput, so even if the vehicle speed when reversing increases, the sorting state is adjusted to a state that corresponds to a large throughput. It never happens.

[Effect of the invention] Therefore, when the aircraft is in the backward state and the grain culm supply detection means detects that the grain culm supply state is in the grain culm supply state,
Since the control operation of the sorting state control means is stopped, the sorting state of the sorting device corresponds to a state where the throughput is large even though the throughput is small due to the retreat of the machine during ridge cutting work etc. It is possible to avoid being controlled by the sorting state.

Therefore, by making effective use of the inherent equipment configuration, even in reaping work where the throughput is small, such as at the edge of a ridge where the machine retreats, the sorting state of the sorting device can be changed to a sorting state that corresponds to the small throughput. I was able to maintain it.

It is provided to automatically stop the gate 2).

Further, in FIG. 11, (S4) is a wheel rotation speed sensor that detects the rotation speed of the wheel (14).

Therefore, by adjusting the spacing (S) between the chaff sieves (21) to a large or small value, and adjusting the flow rate of the sorting air by the comb (14) to be strong or weak, the sorting device (13) can perform sorting according to the size of the throughput. It is configured so that it can be adjusted freely depending on the situation.

Next, the electric motor (M1) for adjusting the interval of the chaff sieve (21) and the electric motor (M1) for adjusting the sorting air volume of the comb (14) are operated, and the sorting device (B
) will be described below.

As shown in FIG. 1, a control device (55) using a microcomputer is provided, and the control device (55) automatically adjusts the sorting state depending on the vehicle speed or automatically adjusts it to a manually set sorting state. a threshing auto switch (S6) for instructing whether or not the vehicle (V) is in a backward state by detecting whether or not the travel transmission (9) is operated to the backward side; back switch (sb
), the stock sensor (S0), the engine rotation speed sensor (S7) that detects the rotation speed of the engine (E), the vehicle speed sensor (S1), the Toumi rotation speed sensor (S4),

A knob potentiometer (Sa) and a knob potentiometer (S6) for adjusting the volume of wind air at the same vehicle speed are connected to each other.

The control device (55) controls the two electric motors (M1), (M1) based on preset and stored information and various input information to control the sorting state of the sorting device (n). is configured to automatically adjust.

However, when the threshing auto switch (S6) is operated to the OFF state, the chaff sheave (21) The opening degree and the amount of airflow can be maintained at manually adjusted positions.

That is, the sorting state control means (10) controls the sorting state of the sorting device (B) by using the control device (55).
0) is constructed.

To explain the adjustment of the sorting state of the sorting device (B), as shown in FIG. As the amount of grain culms introduced into the threshing device (2) increases, the processing amount increases, and the vehicle speed corresponds to the processing amount in the threshing device (2). Based on the detection information of the vehicle speed sensor (S1),
Control is performed so that as the vehicle speed increases, the sorting state corresponding to the state where the throughput becomes larger, that is, the opening degree of the chaff sieve (21) becomes larger and the amount of air sorted by the brush (14) becomes larger.

However, even at the same vehicle speed, the actual throughput may differ due to differences in grain culm grain deposition, etc. Therefore, the chaff opening degree and screening air volume can be adjusted to large or small values at the same vehicle speed. Setting the chaff opening degree and the sorting air volume corresponding to the sorting state at the maximum vehicle speed using the chaff opening adjustment potentiometer (S8) and the chaff air volume adjustment potentiometer (S6), respectively; Based on the sorting state at the set maximum vehicle speed, the standard sorting state is corrected according to the vehicle speed, so that the actual sorting state becomes the sorting state according to the throughput (third step). Figure (+1),
(See (c)).

In addition, during non-reaping operations such as turning when the stock origin sensor (S0) is in the OFF state, and when the machine is retracting, the preset selection state is maintained regardless of the vehicle speed.

Next, the operation of the control device (55) will be described in detail based on the flowchart shown in FIG.

When the control is started, first, it is determined whether the threshing auto switch (S6) is ON or OFF,
When the threshing auto switch (S5) is ON, the chaff opening detection potentiometer (S2) and the milling air volume detection potentiometer (S6) are set based on the respective control target values of the chaff opening and milling air volume. By subtracting the current values detected in each, the toe deviation and the chaff deviation are determined.

However, the respective control target values for the chaff opening degree and the tow air volume are the maximum values adjusted by the chaff opening adjustment potentiometer (S6) and the toe constant air volume adjustment potentiometer (S6), which will be described in detail later. The adjustment value for the vehicle speed is corrected and used according to the vehicle speed, but it is set to a preset standard value each time the control is activated.

On the other hand, when the threshing auto switch (S6) is OFF, the chaff opening degree and the threshing air volume are controlled by the chaff opening adjustment potentiometer (S6) and the threshing wind f
The current value is subtracted from the set adjustment value so as to be maintained at each adjustment value set by each of the f1jJ1 potentiometers (S6), and the values are obtained as the toe deviation and chaff deviation.

Then, based on the detection information of the Toumi rotation speed sensor (S4), the Toumi (14) is rotated at the set rotation speed (500r).
pm) or more, it is determined whether the wheel (14) is rotating.

When the rotational speed of the towing (14) is equal to or higher than the set rotational speed, the rotational speed is reduced so that it is within the set dead zone or the processing amount is small, based on the sign and magnitude of the towing deviation. It is determined whether the toe deviation is on the open side, which weakens the sorting wind, or on the strong side, which corresponds to a large throughput, and if the toe deviation is on the open side, the rotation An electric motor (M2) for adjusting the sorting air is installed on the side where the number is increased.
If it is on the strong side,
A weak output process is performed to lower the rotational speed, and when the rotation speed is within the dead zone, the electric morph (
M2) will be stopped and the current sorting state will be maintained.

Next, it is determined whether the chaff deviation is on the closed side corresponding to a small processing amount, the open side corresponding to a large processing amount, or within the set dead zone, and if it is on the closed side, , performs a weak output process to operate the electric motor (M1) for adjusting the chaff opening degree so as to widen the interval (S) of the chaff sheave (21), and performs a close output process when it is on the open side; If it is within the dead zone, it is stopped and the current sorting state is maintained.

In addition, when the rotation speed of the threshing machine (14) is below the set rotation speed, the threshing air volume is not adjusted, and when the rotation speed of the threshing machine (14) is below the set rotation speed, the threshing auto switch (S6) is Even when it is in the OFF state,
The chaff opening degree can be changed and adjusted.

In other words, as described above, the adjustment of the flow rate of the wind is controlled by the split pulley type transmission ff (42).
Since the threshing device (2) is configured to change the rotation speed of the threshing device (2), it is impossible to adjust the threshing air volume when the threshing device (2) is not in operation.
If the number of revolutions in step 4) is less than the set number of revolutions, the adjustment of the tomi wind star is not performed.

However, when the threshing device (2) described in 11;1 is in operation, the chaff sieve (21) is connected to the sorting device (rS
), it is not possible to check the opening degree of the chaff. Therefore, even when the threshing device (2) is stopped, when the threshing machine (14) is at or below the set rotation speed, the chaff opening degree adjustment cannot be performed. By making it possible to change and adjust the chaff opening degree using the potentiometer (S2), the adjusted state of the chaff opening degree can be easily inspected.

After adjusting each of the above-mentioned blow air volume and chaff opening degree,
In order to control this sorting state every set time (500 ms), after checking the timing at which the set time (500 ms) has elapsed, check whether the back switch (S6) is in the ON state or not. Determine whether

When the back switch (S6) is in the OFF state, it is determined whether the stock stock sensor (S0) is in the ON state.

When the back switch (S6) is OFF and the stock sensor (S0) is ON, it is determined that the reaping work is being performed, and the back switch (S6) is turned OFF for the first time.
By determining whether or not the state has changed from the ON state, it is determined whether the work has started or whether the reaping work is being continuously performed.

The processing when the back switch (S6) is ON and when the back switch (S6) is OFF and the stock sensor (S0) is OFF will be described later.

When the stock sensor (S0) turns ON for the first time, it is determined that work has started, and the engine rotation speed sensor (S0) is turned on.
The current rotation speed according to S6) is set as the reference rotation speed, and if it is not the first time it is turned on, it is determined whether the reference rotation speed is greater than the current rotation speed, and the reference rotation speed is set as the current rotation speed. When the rotation speed is not higher than the rotation speed, that is, when the current rotation speed is higher than the reference rotation speed set at the start of work, the reference rotation speed is updated to the current rotation speed.

Next, the deviation between the reference rotation speed and the current rotation speed is determined as a rotation speed down value, and the rotation speed down value is the set rotation speed (2
00 rpm) or more, it is determined whether the load state on the engine (E) is in an overload state.

If the rotational speed down value is less than the set rotational speed (20 rpm), it is determined that there is no overload condition, and as described above, the slower the vehicle speed, the more the airflow rate becomes open and the chaff opening degree increases. The vehicle speed sensor (
Based on the detection information in step S6), a chaff correction value for correcting the chaff air volume to the open side and a chaff correction value for correcting the chaff opening degree to the closed side are determined according to the vehicle speed (3rd (See Figures (0), 01)).

However, if the rotational speed down value is equal to or higher than the set rotational speed (20 rpm), both the roughness correction value and the chaff correction value are set to zero, and the sorting state of the sorting device (B) is set to the maximum throughput. By controlling to the setting sorting state at the corresponding maximum vehicle speed, the waste to be processed in the threshing device (2) is quickly discharged, and the overload state can be quickly resolved.

After obtaining each of the l-lamin correction value and the chaff correction value, the ON time of the stock source sensor (S0) is set to the first setting corresponding to the time required for the threshing process to stabilize from the start of work. Determine whether the time is longer than (1+・5 seconds),
If the time is less than the first set time, the target value of the air flow rate is set to the first set value (T1) corresponding to a state where the throughput is small.
If the time is longer than the first set time, the value obtained by subtracting the toe correction value from the adjustment value set by the toe constant air volume adjustment potentiometer (S6) is set as the toe target value. .

Similarly, the ON time of the stock sensor (S0) is the second
If the time is less than the set time (t++=5 seconds), the chaff target value, which is the control target value for the chaff opening degree, is set to a second set value (C6) corresponding to a state where the throughput is small; Second
If it is longer than the set time, a value obtained by subtracting the chaff correction value from the adjustment value by the chaff opening adjustment potentiometer (S2) is set, and the control loop in the sorting state completes one cycle.

In other words, each time the control loop goes around, the engine (H
), the correction value set corresponding to the load condition and vehicle speed, and the target value and current value set according to the ON time of the stock sensor (SO), respectively, are within the set inactivity zone. In this way, the chaff opening degree and the amount of wind blowing are automatically adjusted according to the vehicle speed.

When the back switch (S6) is ON, and
To explain the control when the back switch (S6) is OFF and the stock sensor (S0) is OFF, the threshing device is turned off regardless of the vehicle speed during non-reaping operations such as when the machine is retreating or turning. Since the amount of processing in (2) will be smaller, the sorting state corresponding to the smaller amount of processing will be achieved.
The respective target values of the chaff opening degree and the air flow rate are maintained at the current adjustment state until a set time has elapsed after the stock sensor (S0) is turned off, and after the set time has elapsed after the stock sensor (S0) is turned off. , the preset value is maintained as a setting selection state corresponding to a state where the processing amount is small.

That is, if the time elapsed since the stock sensor (S6) was turned off is less than the third set time (tz 5 seconds), the control of the air flow rate is stopped and the current sorting state is maintained. If the time is longer than the third set time, the target value is set to a third set value (T2) that is preset in response to a small processing amount.

Similarly, if the time elapsed since the stock sensor (S0) was turned off is less than the fourth set time (t+z), the control of the chaff opening degree is stopped and the current sorting state is maintained. If the chaff target value is equal to or longer than the fourth set time, the chaff target value is set to a fourth target value (C2) that is preset corresponding to a state where the throughput is small.

Note that the aircraft is in the backward state and the stock sensor (S0) is O.
When in the N state, the stock sensor (S0) is OF
Since the state is the same as when the elapsed time since F is less than the set time, the sorting state immediately before switching to reverse is maintained.

To explain, when reaping work is done at the edge of a ridge, etc., the harvesting work is performed by repeatedly moving back and forth against rows of grain culms in the field. Even though the grain culm is not removed, the cut grain culm is in the conveyance path to the threshing device (2) during the forward movement,
The stock sensor (S0) may be in a state where there is no 0FFL, and even though the throughput is small, the sorting state is controlled according to the vehicle speed, and appropriate sorting corresponding to the small throughput is performed. There is a risk that the condition cannot be maintained.

Since the switch from forward to reverse is operated by switching from forward to reverse after decelerating and stopping, when switching to the reverse state, the sorting state corresponding to a slow vehicle speed, that is, the state corresponding to a state with a small throughput, is performed. Therefore, if the control of the sorting state is stopped and the current sorting state is maintained, the sorting state corresponding to the small processing amount can be automatically maintained.

Furthermore, even during normal forward movement, the processed material remains in the threshing device (2) for a while even after the reaping work is completed and the stock source sensor (S0) is turned off. The current sorting state is maintained until the amount of processed materials decreases.

Therefore, when the stock sensor (S0) is in the ON state, the sorting state at the maximum vehicle speed set by the chaff opening adjustment potentiometer (S8) and the rear airflow adjustment potentiometer (S9) is selected. The adjustment value of When the original sensor (S0) is turned off, control is performed to maintain a preset sorting state, and when the back switch (S6) is turned on and the stock sensor (S0)
If the sorting state control means (100) is not turned off, a series of processing for controlling the control operation to be stopped and the sorting state to be maintained at the current sorting state corresponds to the sorting state control means (100).

〔Betsuji completely defeated〕

In the above embodiment, the vehicle speed sensor (S6) is configured to detect the vehicle speed based on the speed change output rotation speed of the driving transmission (9), and the bank switch (S6) is configured to detect the vehicle speed based on the speed change output rotation speed of the transmission (9). Although the case where the operating state of the transmission device is detected as to whether or not the operating state is in the backward state has been exemplified, it is also possible to indirectly detect the vehicle speed or whether or not the operating state is in the reverse state based on the operating state of the transmission. Often, the specific configurations of the vehicle speed detection means and the backward movement detection means can be changed in various ways.

Further, in the above embodiment, the sorting state of the sorting device (B) is exemplified by controlling both the sorting air volume by the comb (14) and the opening degree of the chaff sieve (21). Only one of them may be controlled.

5. In the above embodiment, the transmission device (42
) is used to change the number of revolutions of the rotor (14) to adjust the screening air volume. However, for example, the rotor (14) may be driven by a variable speed device such as an electric motor. A specific configuration for adjusting the sorting state of the sorting device (B), such as a specific configuration for adjusting the sorting air volume and a specific configuration for adjusting the opening degree of the chaff sieve (21). can be changed in various ways.

Further, in the above embodiment, a potentiometer (Ss) is used to automatically adjust the sorting state of the sorting device (B) according to the vehicle speed.
), (At SJ, the control target value at the maximum vehicle speed is adjusted as a control condition, and the control target value at the maximum vehicle speed is corrected according to the vehicle speed so that it becomes a smaller value as the vehicle speed decreases. For example, multiple sets of combinations of vehicle speed and sorting state set in advance according to the processing amount are stored as control condition parameters, and the sorting states of the plural sets are selected by a switch, etc. The specific configuration of the means for changing and adjusting the target sorting state at the same vehicle speed and the sorting state control means (100) can be changed in various ways.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
