The present invention relates to a combine control system for controlling a combine having a reaping device for reaping field cropping of a field and a threshing device for threshing the reaping cropping remnant harvested by the reaping device.

In addition, the present invention has a harvester for harvesting crops in a field, a harvest tank for storing the harvest harvested by the harvester, and a discharger for discharging the harvest stored in the harvest tank. A harvester control system for controlling a harvester.

[1] Patent Document 1 describes an invention of an automatic travel combine. In the harvesting operation using the combine, the operator manually operates the combine at the beginning of the harvesting operation and performs the mowing travel so as to go around the outer peripheral portion in the field.

During traveling on the outer circumference, the traveling direction of the harvester is recorded. Then, the automatic traveling based on the recorded direction performs the reaping travel in the uncut area in the field.

Here, in the invention described in Patent Document 1, a collecting tank is disposed at an outer peripheral portion in a field. The collection tank is configured to be able to receive and store grains discharged from the discharge cylinder of the combine.

And the combine of patent document 1 is comprised so that reaping driving | running | working in a non-cutting area | region may be performed by repeating the lap | rotation driving | running | working which passes the vicinity of a collection tank. In this round trip, when the combine comes close to the collection tank, the combine stops near the collection tank if it is necessary to discharge the grain. Then, the grains are discharged from the discharge cylinder of the combine into the collection tank.

[2] Patent Document 2 includes a harvesting device for harvesting crops in the field ("the harvesting unit" in Patent Document 2), and a harvest tank for storing the harvested material harvested by the harvesting device (in Invention of a harvester ("Combine" in Patent Document 2) having a grain tank ") and a discharge device (" grain discharge device "in Patent Document 2) for discharging the harvested material stored in the harvest tank Have been described.

Japanese Utility Model Hei 2-107911 Japanese Patent Application Laid-Open No. 2017-35017

[1] Background Art The problems corresponding to [1] are as follows.
In the combine described in Patent Document 1, the combine travels automatically to pass near the collection tank even when it is not necessary to discharge the grain. At this time, the combine travels in the existing area.

That is, in the automatic travel of the combine described in Patent Document 1, the ratio of travel in the already-cut region becomes relatively large. This tends to lower the work efficiency.

Here, in order to improve the working efficiency, the combine is run along the cutting travel path set in the uncut area, and when it becomes necessary to discharge grains etc., the combine is temporarily detached from the cutting travel path A configuration is conceivable which controls the combine so as to make it possible.

In this configuration, after the combine leaves the reaping travel path, the combine travels in the existing reaping area until returning to travel along the reaping travel path. That is, during this time, the combine does not reap the grain census. Therefore, after the combine leaves the reaping travel path, the amount of reaping grain fed to the threshing device decreases.

Here, in the configuration in which the threshing device continues to be driven until return to traveling along the reaping travel route after the combine leaves the reaping travel route, the amount of reaping grain fed to the threshing device decreases. Nevertheless, the threshing device will continue to operate. As a result, the driving of the threshing device is wasted and the threshing efficiency is likely to be reduced. This leads to the deterioration of fuel consumption.

An object of the present invention is to provide a combine control system in which the fuel efficiency of the combine is improved.

[2] Background Art The problems corresponding to [2] are as follows.
Patent Document 2 does not describe in detail the discharge operation by the discharge device. Here, it is conceivable to stop the harvester near the transport vehicle after the transport vehicle is stopped outside the farmland, and to discharge the harvested material to the transport vehicle by the discharge device.

However, when such a discharge operation is performed by a manual operation, the operator needs to move the harvester to the vicinity of the transport vehicle and stop it every time the discharge operation is performed. Furthermore, the more the number of discharge operations, the greater the burden on the operator's operation.

An object of the present invention is to provide a harvester control system capable of reducing the burden of operation by a worker.

[1] The solution means corresponding to the problem [1] is as follows.
A feature of the present invention is a combine control system for controlling a combine comprising a reaping device for reaping a field crop in the field and a threshing device for threshing the reaping crop indwelling by the reaping device, the field control system A reaper traveling path calculation unit that calculates a reaper traveling path that is a traveling path for a reaper traveling at a time, and an automatic reaper traveling control unit that controls the combine so that a reaper traveling is performed by an automatic traveling along the reaper traveling path. And a determination unit that determines whether the threshing efficiency of the threshing device has decreased when the combine has left the harvesting travel path, and the determination unit determines that the threshing efficiency of the threshing device has decreased. And a threshing device stop unit for stopping the operation of the threshing device.

In the case of the present invention, when the threshing efficiency of the threshing device decreases after the combine leaves the cutting travel path, the threshing device stop unit stops driving the threshing device. Therefore, the driving of the threshing device is less likely to be wasted. Thereby, the fuel consumption of the combine is improved.

Furthermore, in the present invention, the threshing apparatus has a rocking and sorting unit for sorting and processing the processed product obtained by the threshing process, and the combine is a processing product which is sorted and processed by the rocking and sorting unit. And the determination unit determines that the threshing efficiency of the threshing device has decreased when the amount of the sorted processing detected by the sheave sensor decreases. Preferably, it is configured.

As the amount of reaping grain fed to the threshing device decreases, the amount of processed material being sorted in the shaking and sorting unit decreases. At this time, the threshing efficiency of the threshing device tends to decrease.

Here, according to the above configuration, it is determined that the threshing efficiency has decreased when the amount of the processed material being sorted in the swinging sorting unit decreases. Therefore, according to the above configuration, it can be accurately determined that the threshing efficiency has decreased.

Furthermore, in the present invention,
Preferably, the determination unit is configured to determine that the threshing efficiency of the threshing device has decreased when the period in which the reaper is not driven continues.

If the reaper continues to be inactive, the amount of reaper supplied to the threshing device will be reduced. At this time, the threshing efficiency of the threshing device tends to decrease.

Here, according to the above configuration, it is determined that the threshing efficiency has decreased when the period in which the reaper is in the non-driven state continues. Therefore, according to the above configuration, it can be accurately determined that the threshing efficiency has decreased.

Furthermore, in the present invention, after the driving of the threshing device is stopped by the threshing device stop unit, the driving of the threshing device is performed when the combine pivots to return to the automatic traveling along the reaping traveling path. It is preferable to provide a threshing device start unit for resuming

In the automatic travel along the reaping travel path, the reaping device harvests the field crop of the field. Along with this, the reaper is fed sequentially to the threshing device. Therefore, in the automatic travel along the reaping travel path, the threshing device needs to be driven.

Here, according to the above configuration, immediately before the combine returns to the automatic traveling along the cutting travel path, the driving of the threshing device is resumed by the threshing device start unit. Thereby, the configuration in which the driving of the threshing device is resumed at an appropriate timing can be realized.

In addition, another feature of the present invention is a combine control program for controlling a combine having a reaping device for reaping field crop straw in a field, and a threshing device for threshing reaping crop straw reaped by the reaping device. There is a reaper traveling path calculating function for calculating a reaper traveling path which is a traveling path for a reaper traveling in a field, and an automatic for controlling the combine so that a reaper traveling is performed by an automatic traveling along the reaper traveling path.

As a result, it is not necessary to stop the harvester at a position for discharging manually by manual operation, not only in the second and subsequent discharging operations but also in the first discharging operation. Therefore, the burden of operation by the operator can be reduced.

Moreover, according to this configuration, when the target stopping position instructed by the instruction signal is inappropriate, the discharging operation is performed if the harvesting machine is moved by manual operation and then the discharging operation is performed.

Further, as shown in FIG. 5, the departure / return route calculation unit 22b calculates the departure / return route LW, which is a traveling route for non-removing travel in the outer peripheral area SA, based on the calculation result received from the area calculation unit 24. Do. As shown in FIG. 5, in the present embodiment, the separation return path LW is a line having a shape along the outer shape of the field.

As shown in FIG. 2, the departure / return route LW calculated by the departure / return route calculation unit 22 b is sent to the traveling control unit 23.

The traveling control unit 23 controls automatic traveling of the combine 1 based on the position coordinates of the combine 1 received from the host vehicle position calculation unit 21 and the departure return route LW received from the departure return route calculation unit 22 b. More specifically, as shown in FIG. 7, when the combine 1 leaves the reaper travel route LI, the travel control unit 23 performs non-removal travel by automatic travel along the detachment return route LW. , Control the travel of Combine 1.

In addition, as described above, the sheave sensor S1 detects the amount of the sorting processed material in the swing sorting unit 13b of the threshing device 13. As shown in FIG. 2, the detection result by the sheave sensor S1 is sent to the determination unit 25.

In addition, the reaper clutch sensor S2 detects the on / off state of the reaper clutch C15. The detection result by the reaper clutch sensor S2 is sent to the determination unit 25.

The determination unit 25 determines whether or not the threshing efficiency of the threshing device 13 has decreased when the combine 1 has left the harvesting travel route LI. More specifically, as shown in FIG. 7, when the combine 1 leaves the reaper traveling route LI, a predetermined signal is sent from the traveling control unit 23 to the determination unit 25 as shown in FIG. This signal is a signal indicating that the combine 1 has left the reaper traveling route LI. If the amount of sorted processed products detected by the sheave sensor S1 decreases after the determination unit 25 receives this signal, the determination unit 25 determines that the threshing efficiency of the threshing device 13 has decreased.

In the present embodiment, the determination unit 25 determines that the threshing efficiency of the threshing device 13 has decreased when the state in which the amount of sorted processed products is level 1 continues for a predetermined first period or longer. That is, continuing the state in which the amount of sorted processed products is level 1 continues for the first period or more corresponds to a decrease in the amount of sorted processed products detected by the sheave sensor S1.

Note that this first period may be, for example, 10 seconds, or may be a period other than that.

As described above, the combine control system A includes the determination unit 25 that determines whether or not the threshing efficiency of the threshing device 13 has decreased when the combine 1 leaves the reaping travel route LI. In addition, the determination unit 25 is configured to determine that the threshing efficiency of the threshing device 13 has decreased when the amount of sorted processed products detected by the sheave sensor S1 has decreased.

Further, as described above, when the combine 1 leaves the reaper traveling route LI, a predetermined signal is sent from the traveling control unit 23 to the determination unit 25. Then, after the determination unit 25 receives this signal, if the period in which the reaper 15 is in a non-driven state continues, the determination unit 25 determines that the threshing efficiency of the threshing device 13 has decreased.

More specifically, when the detection result indicating that the reaper clutch C15 is off is sent from the reaper clutch sensor S2 to the determination unit 25, the determination unit 25 causes the reaper clutch C15 to be continuously off. Count the period. Then, when the period during which the reaper clutch C15 is continuously in the OFF state reaches a predetermined second period, the determination unit 25 determines that the threshing efficiency of the threshing device 13 has decreased. That is, the fact that the period in which the reaper clutch C15 is continuously in the OFF state reaches the second period corresponds to the continuation of the period in which the reaper 15 is in the non-driving state.

Note that this second period may be, for example, 10 seconds, or may be a period other than that.

As described above, the determination unit 25 is configured to determine that the threshing efficiency of the threshing device 13 is reduced when the period in which the reaper 15 is in the non-driven state continues.

The determination result by the determination unit 25 is sent to the threshing device stop unit 27.

The threshing device stop unit 27 switches the threshing clutch C13 from the on state to the off state when the determination unit 25 determines that the threshing efficiency of the threshing device 13 has decreased. Thereby, the driving of the threshing device 13 is stopped.

As described above, the combine control system A includes the threshing device stop unit 27 that stops the driving of the threshing device 13 when the determination unit 25 determines that the threshing efficiency of the threshing device 13 has decreased.

Also, after the driving of the threshing device 13 is stopped by the threshing device stop unit 27, as shown in FIG. 8, when the combine 1 turns to return to the automatic traveling along the reaper traveling route LI, shown in FIG. As described above, a predetermined signal is sent from the traveling control unit 23 to the threshing device start unit 26. This signal is a signal indicating that the combine 1 turns to return to the automatic traveling along the reaper traveling route LI. Upon receiving this signal, the threshing device starting unit 26 switches the threshing clutch C13 from the off state to the on state. Thereby, the driving of the threshing device 13 is resumed.

Thus, after the driving of the threshing device 13 is stopped by the threshing device stop unit 27, the combine control system A performs threshing when the combine 1 turns to return to the automatic traveling along the cutting traveling path LI. The threshing apparatus start part 26 which restarts the drive of the apparatus 13 is provided.

[Flow of harvesting work using combine control system]
In the following, as an example of a harvesting operation using the combine control system A, a flow when the combine 1 performs the harvesting operation in the field shown in FIG. 4 will be described.

First, the operator manually operates the combine 1, and as shown in FIG. 4, in the outer peripheral portion in the field, the mowing travel is performed so as to go around along the border of the field. In the example shown in FIG. 4, the combine 1 performs three rounds. When this round trip is completed, the field is in the state shown in FIG.

The area calculation unit 24 calculates the traveling locus of the combine 1 in the round trip shown in FIG. 4 based on the temporal position coordinate of the combine 1 received from the host vehicle position calculation unit 21. Then, as shown in FIG. 5, the area calculation unit 24 calculates an area on the outer peripheral side of the field where the combine 1 travels while harvesting the set-up kernel based on the calculated travel locus of the combine 1. Calculated as In addition, the area calculation unit 24 calculates the inside of the calculated outer peripheral area SA as the work target area CA.

Next, based on the calculation result received from the area calculation unit 24, the reaper traveling route calculation unit 22a sets a reaper traveling route LI in the work target area CA, as shown in FIG. At this time, the departure / return route calculation unit 22 b calculates the departure / return route LW in the outer peripheral area SA based on the calculation result received from the area calculation unit 24.

Then, when the worker presses an automatic travel start button (not shown), as shown in FIG. 6, automatic travel along the reaper travel path LI is started. At this time, the traveling control unit 23 controls the traveling of the combine 1 so that the reaper traveling is performed by the automatic traveling along the reaper traveling route LI.

While the reaping travel is being performed by the combine 1, as described above, the reaping grain remnants harvested by the reaping device 15 are transported by the transport device 16 to the threshing device 13. Then, in the threshing device 13, the reaping grain is threshed.

In the present embodiment, as shown in FIG. 4 to FIG. 6, the transport vehicle CV is parked out of the field. Then, in the outer peripheral area SA, the stop position PP is set at a position near the transport vehicle CV. As shown in FIG. 5 and FIG. 6, the stop position PP is set at a position overlapping with the leaving return route LW.

The transport vehicle CV can collect and transport the grains discharged from the grain discharging device 18 by the combine 1. When the grain is discharged, the combine 1 stops at the stopping position PP, and discharges the grain to the transport vehicle CV by the grain discharging device 18.

When the combine 1 continues the reaping travel and the amount of grains in the grain tank 14 reaches a predetermined amount, the travel control unit 23 sets the combination 1 so as to separate from the reaping travel path LI, as shown in FIG. Control the run. In addition, as the combine 1 separates from the reaper traveling path LI, the reaper clutch C15 is switched from the on state to the off state.

In the present embodiment, it is assumed that the combine 1 is separated from the cutting travel path LI at a position P1 on the cutting travel path LI shown in FIG.

As shown in FIG. 7, after the combine 1 leaves the reaper traveling route LI, the traveling control unit 23 controls the combine 1 to travel toward the separation return route LW. Then, when the combine 1 reaches the vicinity of the separation return path LW, the traveling control unit 23 controls the traveling of the combine 1 so that the non-removing travel is performed by the automatic traveling along the separation return path LW.

Here, after the combine 1 leaves the reaping travel path LI, the amount of reaping grain fed to the threshing device 13 decreases. In the present embodiment, it is assumed that the amount of the sorted material is reduced from level 5 to level 1 after the combine 1 leaves the reaping travel route LI. Then, it is assumed that the combine 1 is positioned at the position P2 shown in FIG. 7 when the state in which the amount of sorted processed products is level 1 continues for the first period.

In this case, when the combine 1 reaches the position P2, the determination unit 25 determines that the threshing efficiency of the threshing device 13 has decreased. Therefore, at the position P2, the threshing device stopping unit 27 switches the threshing clutch C13 from the on state to the off state. Thereby, the driving of the threshing device 13 is stopped.

As shown in FIG. 7, after passing through the position P2, the combine 1 continues automatic traveling along the departure / return route LW and stops at the stopping position PP. Then, the grain is discharged to the transport vehicle CV by the grain discharging device 18.

After discharging the grain, as shown in FIG. 8, the combine 1 resumes the automatic traveling along the separation return route LW. Then, the combine 1 turns at the position P3 in order to return to the automatic traveling along the reaper traveling route LI. This turning is automatically performed by the control of the traveling control unit 23.

At this time, the threshing device starting unit 26 switches the threshing clutch C13 from the off state to the on state. As a result, the driving of the threshing device 13 resumes at the position P3. At the same time, the reaper clutch C15 is switched from the off state to the on state. Then, the combine 1 returns to automatic travel along the reaping travel route LI at a position P4 on the reaping travel route LI.

The present invention is not limited to this, and the threshing clutch C13 and the reaper clutch C15 may be switched from the off state to the on state at the timing when the combine 1 approaches the uncut portion in the work target area CA. For example, when the distance between the reaper 15 of the combine 1 and the uncut part in the work area CA becomes 2 meters, the threshing clutch C13 and the reaper clutch C15 are switched from the off state to the on state Also good.

Further, the position where the combine 1 returns to the automatic travel along the reaping travel route LI is determined to be the closest position from the stopping position PP among the uncleaved portions in the work target area CA. That is, the position where the combine 1 returns to the automatic traveling along the reaper traveling route LI is determined regardless of the position where the combine 1 has left the reaper traveling route LI. Therefore, the position P1 and the position P4 described above are different.

Then, when the mowing travel along all the mowing travel paths LI in the work target area CA is completed, the entire field becomes harvested.

As described above, in the present embodiment, the traveling of the combine 1 is the traveling control unit until the combine 1 leaves the reaper traveling route LI and starts traveling along the separation return route LW. It is carried out by automatic traveling under control of 23.

Further, in the present embodiment, the traveling of the combine 1 is performed by the automatic traveling under the control of the traveling control unit 23 until the combine 1 leaves the separation return path LW and resumes the traveling along the reaper traveling path LI. It will be.

[About recalculated return route]
By the way, when the combine 1 returns to the automatic traveling along the reaper traveling route LI, the separation return route calculation unit 22b can calculate a re-calculation return route LR different from the separation return route LW. The recalculation return path LR is a travel path for the combine 1 to return to automatic travel along the reaper travel path LI. Hereinafter, the recalculation return path LR will be described.

As described above, the control unit 20 includes the non-traveling area storage unit 28. The travel prohibited area storage unit 28 stores the travel prohibited area PA in the field. As shown in FIG. 2, the departure / return route calculation unit 22 b acquires, from the travel prohibited area storage unit 28, data indicating the travel prohibited area PA.

The travel prohibited area PA is an area where the travel of the combine 1 is prohibited due to the presence of trees and the like in the field.

Further, as shown in FIG. 2, the vehicle position calculation unit 21 sends the position coordinates of the combine 1 with time to the departure / return route calculation unit 22 b.

Then, the departure / return route calculation unit 22b determines whether the work target area CA has not been completed based on the temporal position coordinates of the combine 1 received from the vehicle position calculation unit 21 and the calculation result received from the area calculation unit 24. The cutting area CA1 and the already cut area CA2 are calculated.

Furthermore, the departure / return route calculation unit 22 b may use the data indicating the prohibited travel area PA acquired from the prohibited travel area storage unit 28, the current position coordinates of the combine 1, the calculation result received from the area calculation unit 24, and Based on the uncut area CA1 and the already cut area CA2 calculated as described above, the recalculation return path LR is calculated.

Here, the calculation of the recalculation return path LR is performed according to the following three conditions. That is, the recalculation return route LR must not be a travel route that passes through the travel prohibited area PA. In addition, the recalculation return route LR should not be a travel route passing outside the field. Further, the recalculation return route LR may be a travel route that passes through the already-cleaved area CA2.

Below, as an example of calculation of recalculation return path LR, the flow in the case where recalculation return path LR is calculated in the field shown in FIG. 9 will be described.

FIG. 9 shows that the combine 1 returns from the state where it is stopped at the stopping position PP to the automatic traveling along the reaper traveling route LI.

While the combine 1 is stopped at the stop position PP, the recalculation return route LR is calculated by the departure return route calculation unit 22b. In this calculation, first, of the uncut area CA1 in the work target area CA, the position closest to the stop position PP is calculated. The position calculated at this time is determined as the position for returning to the automatic traveling along the reaper traveling route LI. In the example shown in FIG. 9, the position P5 is determined as the position for returning to the automatic traveling along the reaper traveling route LI.

Next, the departure / return route calculation unit 22b calculates a travel route that is a candidate for the recalculation return route LR. The travel route calculated at this time is a travel route from the stop position PP to the position P5.

More specifically, the departure / return route calculation unit 22b first calculates a first route Rt1 as a candidate for the recalculation return route LR. The first route Rt1 is calculated such that the travel distance from the stopping position PP to the position P5 is relatively short.

However, the first route Rt1 crosses the no travel area PA. That is, since the first route Rt1 is a traveling route passing through the no-traveling area PA, it is excluded from the candidates for the recalculation return route LR.

Next, the departure / return route calculation unit 22b calculates a second route Rt2 and a third route Rt3 as candidates for the recalculation return route LR. The second route Rt2 and the third route Rt3 are calculated so as to bypass the travel prohibited area PA. In addition, the lengths of the second route Rt2 and the third route Rt3 are the same as each other.

Here, a part of the second route Rt2 is located outside the field. That is, since the second route Rt2 is a traveling route passing outside the farmland, it is excluded from the candidates for the recalculation return route LR.

Further, a part of the third route Rt3 is located in the already-cleaved area CA2. That is, the third route Rt3 is a traveling route passing through the already-cleaved area CA2. In addition, the third route Rt3 is not a traveling route passing through the no-traveling area PA. In addition, the third route Rt3 is not a travel route passing outside the field. Therefore, the third route Rt3 remains as a candidate for the recalculation return path LR.

That is, among the above three routes, only the third route Rt3 remains as a candidate for the recalculation return route LR. Therefore, as shown in FIG. 9, the third route Rt3 is selected as the recalculation return path LR.

The departure / return route calculation unit 22 b calculates the re-calculated return route LR as described above. Then, the combine 1 travels along the recalculation return path LR by automatic travel under the control of the travel control unit 23. As a result, the combine 1 returns to automatic traveling along the reaper traveling route LI.

With the configuration described above, when the threshing efficiency of the threshing device 13 decreases after the combine 1 leaves the harvesting travel route LI, the driving of the threshing device 13 is stopped by the threshing device stop unit 27. . Therefore, the driving of the threshing device 13 is less likely to be wasted. Thereby, the fuel consumption of the combine 1 becomes favorable.

[Another Embodiment of the First Embodiment]
Hereinafter, another embodiment in which the above-described embodiment is modified will be described. Except for the matters described in the following different embodiments, the matters are the same as the matters described in the above-described embodiment. The above-described embodiment and the other embodiments described below may be combined as appropriate as long as no contradiction arises. Note that the scope of the present invention is not limited to the above-described embodiment and the following different embodiments.

First Embodiment
In the above embodiment, the traveling of the combine 1 is performed by the automatic traveling under the control of the traveling control unit 23 until the combine 1 leaves the reaper traveling route LI and starts traveling along the separation return route LW. .

Further, in the above-described embodiment, the traveling of the combine 1 is performed by the automatic traveling under the control of the traveling control unit 23 until the combine 1 leaves the separation return path LW and resumes traveling along the reaper traveling path LI. It will be.

However, the present invention is not limited to this. Hereinafter, a first alternative embodiment of the first embodiment will be described focusing on differences from the above embodiment. The configuration other than the parts described below is the same as that of the above embodiment. The same reference numerals are given to the same components as those in the above embodiment.

FIG.10 and FIG.11 is a figure which shows driving | running | working of the combine 1 in 1st another embodiment of 1st Embodiment.

In the first alternative embodiment, when the operator manually operates the combine 1, the combine 1 leaves the reaper traveling route LI. Then, after the combine 1 leaves the reaper drive route LI, when the travel control unit 23 captures the release return route LW, automatic travel is started under the control of the travel control unit 23, and the combine 1 is along the release return route LW. Run automatically.

Further, in the first alternative embodiment, the combine 1 leaves the separation return path LW when the worker manually operates the combine 1. Then, when the travel control unit 23 captures the reaper traveling route LI after the combine 1 leaves the separation return route LW, automatic traveling is started by the control of the travel control unit 23, and the combine 1 is along the reaper traveling route LI. Run automatically.

That is, in the first alternative embodiment, the operator manually operates the combine 1 after the combine 1 leaves the reaper traveling route LI until the traveling control unit 23 captures the separation return route LW. Similarly, after the combine 1 leaves the separation return path LW, the operator manually operates the combine 1 until the traveling control unit 23 captures the reaping travel path LI.

In the following, it will be described in detail that the travel control unit 23 captures the separation return path LW and the reaping travel path LI.

As shown in FIG. 10, after the combine 1 leaves the reaper traveling route LI, the traveling control unit 23 sets a first capture area Ct1. The first capture area Ct1 is a fan-shaped area that extends from the center position in the machine width direction at the front end of the combine 1 to the front side in the traveling direction. Also, the radius and central angle of this sector are radius X and central angle w1.

After the combine 1 separates from the reaper traveling route LI, the traveling control unit 23 monitors whether the first capture area Ct1 overlaps the separation return route LW. Further, after the combine 1 leaves the reaper travel route LI, the travel control unit 23 monitors whether the angle w2 which is the inclination of the combine 1 in the forward direction with respect to the release return route LW is less than or equal to a predetermined angle WA.

Then, when the first capture area Ct1 overlaps the departure return route LW and the angle w2 becomes equal to or less than the predetermined angle WA, the traveling control unit 23 is in a state of capturing the departure return route LW. That is, that the traveling control unit 23 captures the separation return route LW is equivalent to the fact that the first capture region Ct1 overlaps the separation return route LW and the angle w2 becomes equal to or less than the predetermined angle WA.

When the traveling control unit 23 captures the leaving / returning route LW, automatic traveling is started by the control of the traveling control unit 23, and the combine 1 performs automatic traveling along the leaving / returning route LW.

Further, as shown in FIG. 11, after the combine 1 leaves the separation return path LW, the traveling control unit 23 sets a second capture area Ct2. The second capture area Ct2 is a fan-shaped area that extends from the center in the vehicle width direction at the front end of the combine 1 to the front side in the traveling direction. Also, the radius and central angle of this sector are radius Y and central angle r1.

After the combine 1 leaves the separation return route LW, the traveling control unit 23 monitors whether the second capture area Ct2 overlaps the reaper traveling route LI. In addition, after the combine 1 leaves the separation return path LW, the traveling control unit 23 monitors whether the angle r2 which is the inclination in the forward direction of the combine 1 with respect to the reaper traveling path LI is less than or equal to a predetermined angle RA.

Then, when the second capture area Ct2 overlaps the cutting travel path LI and the angle r2 becomes equal to or less than the predetermined angle RA, the travel control unit 23 is in a state of capturing the cutting travel path LI. That is, that the traveling control unit 23 captures the reaper traveling route LI is synonymous with the second capture area Ct2 overlapping the reaper traveling route LI and the angle r2 being equal to or less than a predetermined angle RA.

When the traveling control unit 23 captures the reaper traveling route LI, automatic traveling under control of the traveling control unit 23 is started, and the combine 1 performs automatic traveling along the reaper traveling route LI.

As shown in FIGS. 10 and 11, the radius Y of the second capture area Ct2 is smaller than the radius X of the first capture area Ct1. The central angle r1 of the second capture area Ct2 is smaller than the central angle w1 of the first capture area Ct1. That is, the second capture area Ct2 is set narrower than the first capture area Ct1.

The predetermined angle RA is set to an angle smaller than the predetermined angle WA.

That is, the conditions for the traveling control unit 23 to capture the reaper traveling route LI are set more strictly than the conditions for the traveling control unit 23 to capture the separation return route LW. Accordingly, it is possible to avoid the situation in which the traveling control unit 23 captures the reaping traveling route LI not intended by the operator among the plurality of reaping traveling routes LI in the field. In addition, it is possible to avoid the situation where the reaper traveling route LI is captured by the traveling control unit 23 when the operator does not want traveling along the reaper traveling route LI.

In addition, the reaper traveling route LI and the separation return route LW are virtually set traveling routes, and are not visible to the worker in an actual field. Therefore, when the operator operates the combine 1 to cause the traveling control unit 23 to capture the separation return path LW or the reaping travel path LI, the position of the separation return path LW or the reaping travel path LI is assumed and assumed. The combine 1 is operated to be along the separation return path LW or the reaping travel path LI.

That is, when the separation return route LW or the reaper traveling route LI assumed by the operator and the actual separation return route LW or the reaper traveling route LI deviate from each other, the traveling control unit 23 performs the separation return route LW or the reaper traveling route It becomes difficult to capture LI.

Here, when traveling along the reaper traveling route LI is started, the reaper traveling route LI is located at the end of the uncleaved portion in the work target area CA of the field, and the uncleaved portion and the already-cut region It often extends along the boundary between the parts. Therefore, the deviation between the reaper traveling route LI assumed by the operator and the actual reaper traveling route LI tends to be relatively small.

On the other hand, in the vicinity of the separation return path LW, there are often no marks that help the operator to accurately estimate the position of the separation return path LW. Therefore, the deviation between the leaving return route LW assumed by the worker and the actual leaving return route LW tends to be relatively large. This makes it difficult for the traveling control unit 23 to capture the departure / return route LW.

Therefore, as described above, the conditions for the traveling control unit 23 to capture the leaving return route LW are set looser than the conditions for the traveling control unit 23 to capture the reaper traveling route LI. Thereby, it is easy to avoid the situation where the traveling control unit 23 can not capture the separation return route LW.

The first capture area Ct1 and the second capture area Ct2 may be set simultaneously. That is, when the combine 1 travels at a position where there is neither a separation return route LW nor a reaper traveling route LI, the travel control unit 23 may be able to capture any of the separation return route LW and the reaper traveling route LI. . In this case, of the departure return route LW and the reaping travel route LI, automatic travel may be performed along the travel route captured by the travel control unit 23 first.

The cropped rice bran that has been cut by the reaper 115 is transported by the transport device 116 to the threshing device 113. In the threshing device 113, the reaping grain is threshed. Grains (corresponding to the “harvest” according to the present invention) obtained by the threshing process are stored in a grain tank 114. The grains stored in the grain tank 114 are discharged to the outside by the grain discharging device 118 as needed.

In this way, the combine 101 discharges the grain stored in the grain tank 114, the grain harvester H that harvests the grain in the field, the grain tank 114 that holds grains harvested by the harvester H, and the grain tank 114 And a grain discharging device 118.

Further, the discharge clutch C18 is configured to be changeable between an on state transmitting power and a disconnected state not transmitting power.

When the discharge clutch C18 is in the disengaged state, the power output from the engine 151 is not transmitted to the grain discharge device 118. At this time, the grain discharging device 118 is in a non-driven state.

When the discharge clutch C18 is in the on state, the power output from the engine 151 is transmitted to the grain discharge device 118. At this time, the grain discharging device 118 is driven by the motive power from the engine 151. That is, at this time, the grain discharging device 118 is in the driving state.

Then, as shown in FIG. 13, the satellite positioning module 180 sends positioning data indicating the vehicle position of the combine 101 to the vehicle position calculation unit 121 based on the received GPS signal.

The vehicle position calculation unit 121 calculates position coordinates of the combine 101 with time based on the positioning data output by the satellite positioning module 180. The calculated positional coordinates of the combine 101 with time are sent to the traveling control unit 123 and the area calculation unit 124.

As shown in FIG. 15, the area calculation unit 124 calculates the outer peripheral area SA and the work target area CA based on the temporal position coordinates of the combine 101 received from the host vehicle position calculation unit 121.

More specifically, the area calculation unit 124 calculates the traveling locus of the combine 101 in the circumferential traveling on the outer circumference side of the field based on the temporal position coordinate of the combine 101 received from the vehicle position calculation unit 121. . And the area | region calculation part 124 calculates the area | region by the side of the outer periphery of the farmland which the combine 101 traveled while harvesting the grain as the outer periphery area SA based on the calculated traveling locus of the combine 101. In addition, the area calculation unit 124 calculates the inside of the calculated outer peripheral area SA as the work target area CA.

For example, in FIG. 14, the traveling route of the combine 101 for the circumferential traveling on the outer circumference side of the field is indicated by the arrow. In the example shown in FIG. 14, the combine 101 performs three rounds. When the mowing travel along the travel route is completed, the field is in the state shown in FIG.

As shown in FIG. 15, the area calculation unit 124 calculates an area on the outer circumference side of the field where the combine 101 travels while harvesting the grain as the outer circumference area SA. In addition, the area calculation unit 124 calculates the inside of the calculated outer peripheral area SA as the work target area CA.

Then, as shown in FIG. 13, the calculation result by the area calculation unit 124 is sent to the route calculation unit 122.

Based on the calculation result received from the area calculation unit 124, as illustrated in FIG. 15, the route calculation unit 122 calculates a reaper traveling route LI, which is a traveling route for a reaper traveling in the work area CA. As shown in FIG. 15, in the present embodiment, the cutting traveling path LI is a plurality of parallel lines parallel to one another.

As shown in FIG. 13, the reaping traveling route LI calculated by the route calculating unit 122 is sent to the traveling control unit 123.

The traveling control unit 123 is configured to be able to control the traveling device 111. Then, the traveling control unit 123 controls the automatic traveling of the combine 101 based on the position coordinates of the combine 101 received from the host vehicle position calculation unit 121 and the reaper traveling route LI received from the route calculation unit 122. More specifically, as shown in FIG. 16, the traveling control unit 123 controls the traveling of the combine 101 so that the reaper traveling is performed by the automatic traveling along the reaper traveling route LI.

The manual operation signal transmission unit 125 transmits a predetermined signal to the position storage unit 126 and the direction storage unit 128 when the combine 101 is moved by the manual operation. This signal is a signal indicating that the combine 101 is moved by manual operation.

In addition, the vehicle position calculation unit 121 sends the position coordinates of the combine 101 to the position storage unit 126.

Further, the discharge clutch sensor S11 detects the on / off state of the discharge clutch C18. The detection result of the discharge clutch sensor S11 is sent to the position storage unit 126 and the direction storage unit 128.

When the discharge operation by the grain discharging device 118 is performed at the position where the combine 101 has moved manually, the position storage unit 126 performs the discharging operation of the combine 101 at the time when the discharging operation by the grain discharging device 118 is performed. Memorize the stop position.

More specifically, based on the signal from the manual operation signal transmission unit 125 and the detection result by the discharge clutch sensor S11, the position storage unit 126 sets the grain at the position where the combine 101 has moved by the manual operation. It is monitored whether the discharging operation by the discharging device 118 has been performed.

When the detection result indicating that the discharge clutch C18 is switched from the off state to the on state is sent from the discharge clutch sensor S11 to the position storage unit 126, the position storage unit 126 performs the discharge operation by the grain discharge device 118. Is determined to have been performed.

Then, when the discharging operation by the grain discharging device 118 is performed at the position where the combine 101 has moved by the manual operation, the position storage unit 126 stores the stopping position of the combine 101 at that time.

Thus, in the harvester control system A1, the discharging operation by the grain discharging device 118 is performed when the discharging operation by the grain discharging device 118 is performed at the position where the combine 101 moved by the manual operation. A position storage unit 126 that stores the stop position of the combine 101 at a point of time is provided.

The stop position stored in the position storage unit 126 is sent to the position setting unit 127. Then, the position setting unit 127 sets the target stopping position TP based on the stopping position of the combine 101 stored in the position storage unit 126. The target stopping position TP set by the position setting unit 127 is sent to the traveling control unit 123.

Thus, harvest machine control system A1 is provided with position setting part 127 which sets up target stop position TP based on the stop position of combine 101 memorized by position storage part 126.

The vehicle orientation detection device 181 detects the orientation of the combine 101's fuselage. Then, as shown in FIG. 13, the detection result of the vehicle direction detection device 181 is sent to the direction storage unit 128.

The direction storage unit 128 is used when the grain discharging device 118 performs the discharging operation when the grain discharging device 118 performs the discharging operation at the position where the combine 101 has moved by the manual operation. Remember the orientation of the aircraft.

More specifically, based on the signal from the manual operation signal transmission unit 125 and the detection result by the discharge clutch sensor S11, the direction storage unit 128 makes grains at the position where the combine 101 has moved by the manual operation. It is monitored whether the discharging operation by the discharging device 118 has been performed.

When the detection result indicating that the discharge clutch C18 has switched from the off state to the on state is sent from the discharge clutch sensor S11 to the direction storage unit 128, the direction storage unit 128 performs the discharge operation by the grain discharge device 118. Is determined to have been performed.

Then, when the discharging operation by the grain discharging device 118 is performed at the position where the combine 101 has been moved by the manual operation, the direction storage unit 128 stores the orientation of the fuselage of the combine 101 at that time.

Thus, in the harvester control system A1, the discharging operation by the grain discharging device 118 is performed when the discharging operation by the grain discharging device 118 is performed at the position where the combine 101 moved by the manual operation. The direction storage unit 128 stores the orientation of the combine 101 at the time point.

The orientation of the airframe stored in the direction storage unit 128 is sent to the direction setting unit 129. Then, the direction setting unit 129 sets the target stopping direction TD based on the direction of the airframe of the combine 101 stored in the direction storage unit 128. The target stopping direction TD set by the direction setting unit 129 is sent to the traveling control unit 123.

Thus, harvest machine control system A1 is provided with the direction setting part 129 which sets the target stop direction TD based on the direction of the body of the combine 101 memorize | stored in the direction memory | storage part 128. FIG.

The traveling control unit 123 travels the combine 101 so that the combine 101 automatically stops at the target stopping position TP with the combine 101 facing the target stopping direction TD when the grain discharging device 118 performs the discharging operation. Control.

Thus, the harvester control system A1 controls the traveling of the combine 101 so that the combine 101 automatically stops at the target stopping position TP when the grain discharging device 118 performs the discharging operation. It has 123.

[Flow of harvesting work using combine control system]
In the following, as an example of a harvesting operation using the harvester control system A1, a flow in the case where the combine 101 performs the harvesting operation in the field shown in FIG. 14 will be described.

First, the operator manually operates the combine 101, and as shown in FIG. 14, in the outer peripheral portion in the field, the mowing travel is performed so as to go around along the border of the field. In the example shown in FIG. 14, the combine 101 performs three rounds. When this round trip is completed, the field is in the state shown in FIG.

The area calculation unit 124 calculates the traveling locus of the combine 101 in the round trip shown in FIG. 14 based on the temporal position coordinate of the combine 101 received from the host vehicle position calculation unit 121. Then, as shown in FIG. 15, the area calculation unit 124 calculates an area on the outer circumference side of the field where the combine 101 travels while harvesting the set-up kernel based on the calculated traveling locus of the combine 101. Calculated as In addition, the area calculation unit 124 calculates the inside of the calculated outer peripheral area SA as the work target area CA.

Next, based on the calculation result received from the area calculation unit 124, as shown in FIG. 15, the route calculation unit 122 sets the reaper traveling route LI in the work target area CA.

In the example shown in FIG. 15, the combine 101 is moved to the vicinity of the transport vehicle CV by manual operation before starting the harvesting work in the work target area CA. In the present embodiment, the transporter CV is stopped outside the field.

Then, after the combine 101 is stopped in the vicinity of the transport vehicle CV, the grain discharging device 118 is driven to discharge the grains. The transport vehicle CV can collect and transport grains discharged by the combine 101 from the grain discharging device 118.

At this time, the position storage unit 126 stores the stopping position of the combine 101 at the time when the grain discharging device 118 performs the discharging operation. The direction storage unit 128 also stores the orientation of the combine 101 at the time when the grain discharging device 118 performs the discharging operation.

Then, as shown in FIG. 16, based on the stop position stored by the position storage unit 126, the position setting unit 127 sets the target stop position TP. Further, the target stopping direction TD is set by the direction setting unit 129 based on the orientation of the vehicle stored by the direction storage unit 128.

Then, when the worker presses an automatic travel start button (not shown), as shown in FIG. 16, automatic travel along the reaper travel path LI is started. At this time, the traveling control unit 123 controls the traveling of the combine 101 so that the reaper traveling is performed by the automatic traveling along the reaper traveling route LI.

When the combine 101 continues the reaping travel and the amount of grains in the grain tank 114 reaches a predetermined amount, the travel control unit 123 separates from the reaping travel path LI as shown in FIG. The travel of the combine 101 is controlled to move to the right.

Then, under the control of the traveling control unit 123, the combine 101 automatically stops at the target stopping position TP while facing the target stopping direction TD. Furthermore, the grain discharging device 118 is driven, and the grains are discharged to the transporter CV. When the discharging operation by the grain discharging device 118 is completed, the combine 101 returns to the reaping travel along the reaping travel path LI.

In the configuration described above, when the first discharging operation is performed in the field, the position storage unit 126 stores the stopping position of the combine 101 at that time. Then, in the second and subsequent discharge operations, the combine 101 automatically stops at the stored stop position under the control of the travel control unit 123.

That is, with the configuration described above, it is only the first discharging operation that it is necessary to stop the combine 101 at the position for discharging manually. Thereby, the burden of operation by a worker can be reduced.

[About setting of target stop position via communication terminal]
By the way, harvest machine control system A1 is constituted so that a worker can set up target stop position TP via communication terminal 104, before the first discharge work by grain discharge device 118 is performed in the field of harvest work. It is done.

Hereinafter, setting of the target stopping position TP via the communication terminal 104 will be described.

As shown in FIG. 13, the communication terminal 104 has an operation unit 104 a and a signal output unit 104 b. As shown in FIG. 18, the operation unit 104a is configured by a touch panel. Then, the operator can set the target stopping position TP by operating the operation unit 104a before the first discharging operation by the grain discharging device 118 is performed in the field of the harvesting operation.

If it explains in full detail, as shown in Drawing 18, the whole view of a field is displayed on operation part 104a. Then, when the operator touches an arbitrary part of the operation unit 104a, a symbol indicating the target stopping position TP is displayed at the touched part.

Then, as shown in FIG. 13, a signal indicating a portion touched by the worker is sent from the operation unit 104 a to the signal output unit 104 b. The signal output unit 104b outputs an instruction signal based on the signal received from the operation unit 104a.

The instruction signal is a signal indicating the stopping position of the combine 101 for the discharge operation by the grain discharging device 118. Then, the instruction signal is sent to the position setting unit 127.

Thus, harvest machine control system A1 is provided with the signal output part 104b which outputs the instruction | indication signal which instruct | indicates the stop position of the combine 101 for the discharge | emission operation | work by the grain discharge device 118. FIG.

At this time, the position setting unit 127 sets the target stopping position TP based on the instruction signal received from the signal output unit 104 b.

As described above, when the signal output unit 104 b outputs the instruction signal before the first discharging operation by the grain discharging device 118 is performed in the field, the position setting unit 127 sets the target based on the instruction signal. The stop position TP is set.

With the above configuration, the operator can set the target stopping position TP by operating the operation unit 104a before the first discharging operation by the grain discharging device 118 is performed in the field of the harvesting operation. When the discharging operation is performed, the combine 101 automatically stops at the target stopping position TP set based on the instruction signal from the signal output unit 104b.

Here, the target stopping position TP set based on the instruction signal from the signal output unit 104 b is set based on the touch operation by the worker. Therefore, the target stopping position TP may be located relatively far from the transport vehicle CV.

In this case, as shown in FIG. 19, after the combine 101 automatically stops at the target stop position TP set based on the instruction signal from the signal output unit 104b, the operator can start from the position The combine 101 can be moved by manual operation.

Then, when discharge operation is performed by the grain discharging device 118 after the combine 101 is moved by manual operation, the position storage unit 126 stops the combine 101 at the time of discharging operation by the grain discharging device 118. Remember the position. The direction storage unit 128 also stores the orientation of the combine 101 at the time when the grain discharging device 118 performs the discharging operation.

The position setting unit 127 resets the target stopping position TP as shown in FIG. 19 based on the stopping position stored in the position storage unit 126 at this time. The direction setting unit 129 also sets the target stopping direction TD, as shown in FIG. 19, based on the orientation of the vehicle stored in the direction storage unit 128 at this time.

As described above, the position setting unit 127 performs the position storage unit when the discharge operation is performed by the grain discharging device 118 after the combine 101 is moved by the manual operation from the target stopping position TP set based on the instruction signal. Based on the stop position of the combine 101 stored in 126, the target stop position TP is reset.
