Shift control means for operating the speed change means is provided,
The shift control means is
Based on the detection information of the actual traveling speed detection means, the cutting device is stopped when the traveling device stops and reverses, and the driving speed of the cutting device is determined when the traveling device moves forward. The present invention relates to a combined shift control device configured to execute a travel-linked shift process in which a shift operation of the shift means is performed so as to be set to a higher speed as the travel speed of the vehicle becomes higher.

The combine is for harvesting cereals planted in the field as it travels, and threshing with a threshing device.

JP 2003-250326 A

  In the above-described combine shift control device, there is a possibility that the actual traveling speed detecting means may break down and the actual traveling speed detecting means may output zero even though the traveling apparatus is traveling. The cutting processing device cannot be driven by the traveling linkage shift process, and the harvesting work cannot be performed.

  In other words, in general, the actual traveling speed detecting means is attached to a rotating body that rotates integrally with the traveling device, with a detecting body provided with irregularities on the outer peripheral portion, and fixedly installed corresponding to the outer peripheral portion of the detecting body. In many cases, an unevenness detecting sensor for detecting unevenness of a detection body and an arithmetic unit for obtaining the number of times the unevenness detection sensor detects protrusions per unit time as the rotation speed of the detection body are provided. In the case of such a configuration, if the unevenness detecting sensor detects a concave or a convex so as to output the same signal even if a convex is detected, zero is output from the arithmetic unit. In addition, even if the unevenness detection sensor detects properly, the detection signal is not properly input to the calculation unit. As a result, zero is output from the calculation unit. May output zero A.

When the actual travel speed detecting means breaks down and outputs zero, as a result of the shift control means executing the travel linkage shift process, even if the travel device moves forward, the harvesting processing device is not driven, and the harvesting harvesting is performed. The work cannot be performed.
However, it is desirable to concentrate the harvesting and harvesting operations at a time suitable for harvesting. The situation where harvesting and harvesting operations cannot be performed using a combine at a time suitable for harvesting is appropriate. It is necessary to avoid it.

  The present invention has been made in view of the above circumstances, and its purpose is that the actual traveling speed detecting means may output zero due to a failure or the like even though the traveling device is traveling. Another object of the present invention is to provide a combine shift control device capable of driving the harvesting processing device by the traveling linkage shift processing.

The feature of the present invention is that
Speed change means for changing the driving speed of the cutting processing device that causes the traveling speed and cereal of the traveling device to cause cutting and supply to the threshing device;
A travel speed changer for operating the speed change means to change the travel speed of the travel device;
An actual traveling speed detecting means for detecting a traveling speed of the traveling apparatus by detecting the rotating body integrally rotating with the traveling apparatus;
Shift control means for operating the speed change means, and
The shift control means is
Based on the detection information of the actual traveling speed detection means, the cutting device is stopped when the traveling device stops and reverses, and the driving speed of the cutting device is determined when the traveling device moves forward. A combined shift control device configured to execute a travel-related shift process for shifting the speed change means so as to be set to a higher speed as the travel speed of the vehicle increases.
A target travel speed detecting means for detecting a target travel speed commanded by the travel speed change operation tool is provided;
When the travel speed detected by the actual travel speed detecting means is zero, the speed change control means is configured to command the target travel commanded by the travel speed change operation tool based on the detection information of the target travel speed detecting means. The traveling linkage shift process is executed with the speed as the traveling speed,
Manual operation type mowing drive command means is provided that can be switched between a drive command state for commanding a drive command for driving the mowing processing device and a command release state for commanding a release command for releasing the driving command of the mowing processing device. ,
The shift control means is
When the release command is commanded by the cutting drive command means, the travel linkage shift process is executed, and when the drive command is commanded by the harvest drive command means, The reaping processing device is configured to execute a non-associative shifting process for shifting the shifting means so as to drive the reaping processing device at a set target driving speed. The reaping driving command means drives the reaping processing device in the driving command state. It is configured to command a speed indicator that indicates the level of speed,
The speed change control means is configured to determine the set target drive speed in the unlinked speed change process in a state where the speed index commanded by the cutting drive command means is higher as the speed index is higher.
The cutting drive command means is a neutral position that is biased to return, a command operation tool that can be moved to the side away from the neutral position, a position detection sensor that detects the position of the command operation tool, command control means, Consisting of
The command control means commands the release command when the command operating tool is positioned in the neutral operation area on the neutral position side based on the detection information of the position detection sensor, and the command operating tool is in the neutral position. When it is located in the command operation area on the side farther from the neutral position than the operation area, the drive command is commanded, and in addition, the command operation tool becomes faster as it is located on the side away from the neutral position in the command operation area. Configured to command the speed indicator;
When the command operation tool is positioned in the front side range that is the neutral position side in the command operation range, the command control means commands a speed index of a set low speed as the speed index, and the command control unit When the command operating tool is positioned in the rear range farther from the neutral position than the front range, the lower the set low speed as the command operating tool is positioned on the side farther from the neutral position as the speed index. The speed index is configured to command a speed index that gradually increases from the speed index.

That is, when the travel speed detected by the actual travel speed detecting means is zero, the shift control means performs the travel linkage shift process using the target travel speed commanded by the travel shift operation tool as the travel speed. .
As described above, since the traveling linkage process can be performed even when the traveling speed detected by the actual traveling speed detecting means is zero, the actual traveling speed detecting means may output zero due to a failure or the like. Even in such a case, it is possible to drive the cutting processing device by the traveling linkage shift processing, and it is possible to avoid the trouble that the combine cannot be used at a time suitable for cutting due to a failure of the actual traveling speed detecting means or the like. .

Incidentally, it is conceivable that the travel linkage shift process is always performed with the target travel speed commanded by the travel shift operation tool as the travel speed. However, the target travel speed commanded by the travel shift operation tool and the actual travel speed are considered. The running speed detected by the speed detecting means does not necessarily match due to various factors such as individual differences of the speed changing means, and the driving speed of the reaping processing device is determined in relation to the running speed. In order to achieve the set related speed, it is preferable to perform the travel linkage shift process based on the travel speed detected by the actual travel speed detecting means.
In addition, by commanding the drive command by the cutting drive command means, the shift control means shifts the speed change operation means so as to drive the cutting processing device at a preset target drive speed. Therefore, even when the traveling device is stopped or moving backward, the reaping processing device can be driven.
For example, when a combine harvester performs a harvesting and harvesting operation while traveling forward toward the reed during pillow cutting, for example, when the combine stops traveling at the reed and continues to move backward, The driving of the harvesting processing device will be stopped, but if the harvested cereals remain in the grain transporting path for transporting the harvested cereals in the harvesting processing device to the threshing device, the harvested cereals are threshed. In some cases, it may be desirable to temporarily drive the reaping processing device to supply it to the device.
In such a case, the cutting processing device can be driven by instructing the driving command by the cutting drive command means.
Incidentally, when the traveling device is stopped, the cutting processing device can be driven for maintenance and inspection work by instructing a driving command by the cutting driving command means.
Further, in the drive command state in which the drive command is issued by the cutting drive command means, the set target drive speed can be changed to high or low by commanding a speed index indicating the level of the drive speed of the cutting processing device. Therefore, the driving speed of the cutting processing device when supplying the harvested wheat straw remaining in the grain transporting path of the harvesting processing device to the threshing device, and the cutting processing when entering the wheat straw group in the field The drive speed of the device can be adjusted to an appropriate speed according to the state of the grain straws, etc. In such a case, the slaughtering device is driven at a higher driving speed than the speed driven by the traveling linkage shift process in order to cause the cereal and perform the reaping process. The are culms also than the one that can be properly caused by cutting process, and what can be improved workability.
By the way, when driving the mowing processing device for maintenance inspection work by commanding the driving command by the mowing driving command means when the traveling device is stopped, the driving speed of the mowing processing device is increased or decreased. Since the set target drive speed can be changed to high or low by commanding the speed index shown, maintenance and inspection work can be performed while changing the drive speed of the cutting processing device to high or low. .
Further, by operating the command operating tool away from the neutral position against the return urging force and operating it in the command operating range, it is possible to command a drive command, and when canceling the operation on the command operating tool, The command operating tool returns to the neutral operation range by the return biasing force, and the release command is commanded. In the command operation area, a higher speed index can be commanded as the command operating tool is operated away from the neutral position.
In this way, the drive command can be commanded by simply operating the command operating tool in the command operating range against the return biasing force from the neutral position, and the operation on the command operating tool can be released. By simply doing, it is possible to accurately issue a release command.
In the command operation area, the speed index can be changed by a simple operation that only changes the position of the command operation tool. In addition, the speed of operation increases as the command operation tool is moved away from the neutral position. Therefore, while monitoring the driving state of the reaping processing device, it can be gradually operated to the high speed side, and it is driven unnecessarily at high speed so as not to damage the cereal. It becomes easy to drive the cutting processing device at an appropriate driving speed.
By the way, as explained in the section of the above-mentioned fourth characteristic configuration, when the traveling device is stopped, a driving command is commanded by the cutting drive command means, and the driving speed of the cutting processing device is indicated. By instructing the speed index, maintenance and inspection work can be performed while changing the driving speed of the cutting processing device to high or low, but the command operation tool is urged to return to the neutral position, so the command It is necessary to hold the operating tool against the return urging force, and it is desirable to employ the above-described second characteristic configuration when performing maintenance and inspection work on the cutting processing device.
When the command operating tool is operated to the front range on the neutral position side in the command operating range, the set target drive speed is set to the set low speed regardless of the position of the command operating tool in the front range. When the command operating tool is operated toward the side away from the neutral position in the rear range, which is the side farther from the neutral position than the front range in the operation area, the set target drive speed is changed from the set low speed. The speed is gradually determined to be higher.
In other words, when the harvested cedar remains in the reaping processing device during the pillow trimming operation, the target speed when driving the reaping processing device by instructing the drive command by the reaping drive command means is the traveling Considering that the vehicle is stopped or traveling at a low speed, a constant and low speed is preferable, and such a target speed is set when the command operating tool is positioned in the front range in the command operating range. By doing so, when the command operating tool is operated to the front side range, the harvesting processing device can be driven at a speed convenient for supplying the cereal residue remaining in the harvesting processing device to the threshing device. Moreover, since the cutting processing device can be driven at such a speed by operating the command operating tool in the front range defined as the range, the cereal remaining in the cutting processing device can be removed. The operation of driving the threshing device to be supplied to the threshing device is easy to perform.
In addition, if the command operating tool is operated toward the side away from the neutral position in the rear range of the command operation range, the target drive speed can be set gradually higher. When the grain culm in the field is partially lying down, the set target drive speed can be set by changing the command operating tool in the rear range. It can be done with appropriate settings.

Therefore,
Even if the traveling device is traveling, even if the actual traveling speed detection means may output zero due to a failure or the like, it is possible to drive the reaping processing device by the traveling linkage shift process,
It is possible to satisfactorily supply the cereal residue remaining in the harvesting processing device to the threshing device,
Workability can be improved,
The drive command and the release command can be commanded by a simple operation, and it is easy to drive the cutting processing device at an appropriate drive speed while avoiding unnecessary high speed driving. ,
It is easy to drive the threshing device so that the cereal residue remaining in the reaping processing device is supplied to the threshing device, and it is also possible to appropriately operate the reaping processing device to drive at high speed. A shift control device has been provided.

The present invention also provides:
A high-speed shift state that is provided on the upper side of the power transmission direction than the travel device and that shifts the output from the engine at a high speed and transmits the output to the travel device, and a low speed that shifts the output to a low speed and transmits the output to the travel device Sub-transmission means is provided that can be switched between a shift state and a neutral state where the output is not transmitted to the travel device,
The actual traveling speed detecting means detects the traveling speed of the traveling apparatus by detecting and acting on a rotating body located on the lower side of the power transmission direction than the auxiliary transmission means as a rotating body that rotates integrally with the traveling apparatus. It is preferable to be configured as follows.

  That is, it is desirable for the combine to travel at a higher speed when traveling on a headland or traveling on a road in the field than on a traveling speed when performing harvest harvesting work in the field. Since there is provided a sub-transmission means that can be switched between a shifting state and a neutral state in which the output transmitted from the transmission means to the traveling device is changed to a high or low level, by appropriately switching the sub-transmission means, It is possible to appropriately run at the corresponding running speed.

Then, the actual travel detection means is configured to detect the travel speed of the travel device by detecting and acting on the rotary body located on the lower side of the power transmission direction than the sub-transmission means as a rotational body that rotates integrally with the travel device. Therefore, if the sub-transmission means is set to the neutral state and the speed change means is operated by the travel speed change tool, the travel speed change tool will instruct the actual travel speed detection means to detect zero. The travel linkage shift process is performed using the target travel speed as the travel speed.
As described above, since the harvesting processing device can be driven while changing the driving speed by operating the traveling speed change operation tool with the traveling of the combine stopped, the harvesting processing device is driven for inspection and maintenance work. Can be performed satisfactorily.

  By the way, in general, the travel gear operating tool is configured to be held at the operation position when the position change operation is performed for shifting, so that the driving speed of the cutting processing device is used for inspection and maintenance. If the traveling speed change operation tool is operated at a suitable speed, the hand can be released from the traveling speed change operation tool, and it is easy to perform inspection and maintenance work of the cutting processing device.

  Therefore, it is possible to appropriately travel at a traveling speed according to the traveling state, and it is possible to satisfactorily drive the cutting processing device for inspection and maintenance work.

The present invention also provides:
It is preferable that the command operation tool is a stepping operation type stepping pedal provided at a step portion of a driver seat in a state where the stepping operation as the neutral position is returned to the released position.

That is, since the command operating tool is a stepping operation type stepping pedal provided in a state where the stepping position as the neutral position is released and biased to the stepped portion of the driver's seat, the operator sitting on the driver's seat By depressing the depressing pedal and adjusting the depressing amount, a drive command can be commanded and a speed index can be commanded, and a release command can be commanded by releasing the depressing step .
In this way, by operating the depression pedal, it is possible to issue a drive command or a release command, and it is also possible to command a speed index, so that an operator seated in the driver's seat can perform steering operations and fingers It is possible to issue a drive command or a release command with the foot while performing a steering operation such as a speed change operation of the traveling speed, and it is also possible to command a speed index.

  Therefore, it is possible to satisfactorily issue a drive command, a release command, and a speed index command while performing a steering operation, a speed change operation, and the like.

The present invention also provides:
Driving speed of the reaping processing device when the shift control means assumes that the set target driving speed determined based on the command of the reaping drive command means executes the travel linking speed change process in the non-associative shifting process Is lower, the driving linkage is driven at the driving speed of the reaping processing device when it is assumed that the traveling linkage shift processing is executed, and the setting determined based on the command of the reaping drive command means When the target drive speed is the same as or higher than the drive speed of the reaping processing apparatus when it is assumed that the traveling linkage shift process is executed, the reaping processing apparatus should be driven at the set target drive speed. It is preferable that the speed change means is configured to change speed.

That is, when it is assumed that when the driving command is issued and the speed index is commanded by the cutting drive command means, the set target driving speed determined based on the command of the cutting drive command means executes the traveling linkage shift process. When the driving speed of the cutting processing device is lower than the driving speed of the cutting processing device, the cutting processing device is driven at the driving speed of the cutting processing device when it is assumed that the traveling linkage shift processing is executed. The driving speed of the cutting processing device when it is assumed that when the driving command is issued and the speed index is commanded, the set target driving speed determined based on the command of the cutting driving command means executes the traveling linkage shift process. When the speed is higher than the same and the driving speed, the cutting processing device is driven at the set target driving speed.
That is, when the traveling device is moving forward, in other words, when the traveling linkage shift process is being performed, the driving command is commanded by the cutting drive command means when the harvesting operation is being performed. For example, when the cereals in the field are partially lying down, or when entering the group of cereals in the field and starting the cutting operation, etc. An object of the present invention is to drive the reaping processing apparatus being driven at a speed higher than the driving speed. In such a case, if the driving speed of the reaping processing device is lower than the driving speed of the reaping processing device driven by the traveling linkage shift process, it becomes difficult to cause the culm to cause the reaping process more appropriately. It will be a thing.

In this configuration, when the set target drive speed determined based on the command of the cutting drive command means is higher than the drive speed of the cutting processing device when it is assumed that the traveling linkage shift process is executed, the command of the cutting drive command means is Although the cutting processing device is driven at the set target driving speed determined on the basis of the cutting target processing speed, it is assumed that the set target driving speed determined based on the command from the cutting driving command means executes the traveling linkage shift processing. When the driving speed is lower than the driving speed, the cutting processing apparatus is driven at the driving speed of the cutting processing apparatus when it is assumed that the traveling linkage shift process is executed. Therefore, the driving speed of the cutting processing apparatus is unnecessarily low. It is possible to operate at a high speed while avoiding the above.
Accordingly, it is possible to accurately operate at high speed while avoiding unnecessarily reducing the driving speed of the reaping processing apparatus.
Another feature of the present invention is that

The traveling linkage shift process is executed with the speed as the traveling speed,
Manual operation type mowing drive command means is provided that can be switched between a drive command state for commanding a drive command for driving the mowing processing device and a command release state for commanding a release command for releasing the driving command of the mowing processing device. ,
The shift control means is
When the release command is commanded by the cutting drive command means, the travel linkage shift process is executed, and when the drive command is commanded by the harvest drive command means, It is configured to execute a non-associative shift process for shifting the shift means so as to drive the cutting processing device at a set target drive speed,
Driving speed of the reaping processing device when the shift control means assumes that the set target driving speed determined based on the command of the reaping drive command means executes the travel linking speed change process in the non-associative shifting process Is lower, the driving linkage is driven at the driving speed of the reaping processing device when it is assumed that the traveling linkage shift processing is executed, and the setting determined based on the command of the reaping drive command means When the target drive speed is the same as or higher than the drive speed of the reaping processing apparatus when it is assumed that the traveling linkage shift process is executed, the reaping processing apparatus should be driven at the set target drive speed. The transmission means is configured to perform a speed change operation.
And this invention,
A high-speed shift state that is provided on the upper side of the power transmission direction than the travel device and that shifts the output from the engine at a high speed and transmits the output to the travel device, and a low speed that shifts the output to a low speed and transmits the output to the travel device Sub-transmission means is provided that can be switched between a shift state and a neutral state where the output is not transmitted to the travel device,
The actual traveling speed detecting means detects the traveling speed of the traveling apparatus by detecting and acting on a rotating body located on the lower side of the power transmission direction than the auxiliary transmission means as a rotating body that rotates integrally with the traveling apparatus. It is preferable to be configured as follows.
The present invention also provides:
The cutting drive command means is configured to command a speed index indicating the level of the driving speed of the cutting processing device in the drive command state,
The speed change control means is configured to determine the set target drive speed in the unlinked speed change process in such a state that the higher the speed index commanded by the cutting drive command means, the higher the speed index. Is preferred.
Furthermore, the present invention provides
The cutting drive command means includes a neutral position that has been biased to return, a command operation tool that can be moved and moved away from the neutral position, a position detection sensor that detects the position of the command operation tool, and a command control means. Configured,
The command control means commands the release command when the command operating tool is positioned in the neutral operation area on the neutral position side based on the detection information of the position detection sensor, and the command operating tool is in the neutral position. When it is located in the command operation area on the side farther from the neutral position than the operation area, the drive command is commanded, and in addition, the command operation tool becomes faster as it is located on the side away from the neutral position in the command operation area. It is preferable that the speed index is configured to be commanded.
Furthermore, the present invention provides

The present invention also provides:
The set target drive speed is determined by setting a speed lower than the maximum speed among the drive speeds of the reaping processing apparatus when the shift control means is assumed to execute the travel linkage shift process as a maximum speed. It is preferable to be configured.

That is, the cutting target driving speed of the cutting processing device is set by the cutting drive command means with a speed lower than the maximum speed among the driving speeds of the cutting processing device when it is assumed that the traveling linkage shift processing is executed. Will be changed.
In other words, when cutting and harvesting work while traveling, if the cereals in the field are partially lying down, the traveling speed should be set lower than the maximum speed that can be changed. The set target drive speed of the reaping processing device that can be changed and set by the reaping drive command means is the maximum speed among the driving speeds of the reaping processing device when it is assumed that the traveling linkage shift process is executed. If the speeds are the same, there is a possibility of causing troubles such as damaging the cereal by changing and setting the target drive speed of the reaping processing apparatus unnecessarily high due to an erroneous operation.

According to this configuration, it is possible not to set the target driving speed of the cutting processing device to an unnecessary high speed by the cutting drive command means and to generate troubles such as damaging the cereal. It can be suppressed.
Therefore, it is possible to avoid setting the setting target drive speed of the reaping processing device to an unnecessary high speed .

The travel transmission apparatus S is operated so that the high speed forward state is operated, and further, as the shift operation lever 24 is operated to the side away from the travel neutral position N in the reverse travel region R, the high speed reverse state is achieved. In order to operate S, the control means H is configured to control the operation of the traveling electric motor 27.

  As shown in FIG. 4, the swing operation is performed to the clutch disengagement position n, the threshing clutch engagement command position D for commanding the engagement of the threshing clutch 14, and the clutch engagement command position Y for commanding the engagement of the threshing clutch 14 and the mowing clutch 15. A free clutch operation lever 44 is provided at a side portion of the driver's seat 2, and detection information of a position detection sensor 45 that detects an operation position of the clutch operation lever 44 is input to the control means H. Then, the control means H is configured to operate the threshing clutch operating electric motor 46 and the reaping clutch operating electric motor 47 based on the information of the position detection sensor 45 to perform the on / off operation of the threshing clutch 14 and the reaping clutch 15. ing.

Then, the control means H cuts based on the detection information of the lift position sensor 49 in a state where the execution command state is commanded by the cutting auto command switch 48 and the clutch operating lever 44 is operated to the clutch engagement command position Y. When it is detected that the processing device 4 is raised by a set height or more with respect to the traveling vehicle body B, the cutting clutch 15 is operated to be disconnected, and the cutting processing device 4 is operated based on the detection information of the lift position sensor 49. When it is detected that the traveling vehicle body B is lowered to a position lower than the set height, the cutting clutch 15 is engaged and operated.

As shown in FIG. 4, a steering lever 42 that is swingable in the front-rear direction and the left-right direction is provided at the front portion of the driver seat 2, and the steering lever 42 is operated forward from the neutral position. When the control lever 42 is operated backward from the neutral position, the elevation command switch 41 that commands the elevation command is operated. Then, the command information of the raising / lowering command switch 41 is input to the control means H, and the control means H controls the control valve 7A of the hydraulic cylinder 7 for raising / lowering the cutting processing device 4 based on the ascending command and the descending command. Is operated to raise and lower the cutting processing device 4.
Although not described in detail, when the control lever 42 is operated leftward from the neutral position, a left turn is commanded, and when the control lever 42 is operated rightward from the neutral position, a right turn is commanded. A turn command switch 40 is provided. Then, the command information of the turn command switch 40 is input to the control means H, and the control means H switches the pair of left and right traveling devices 1 to the turn drive state based on the left turn command and the right turn command. The driving means (not shown) is operated to turn.

  The operation of the cutting transmission device K will be described. As shown in FIG. 4, a cutting speed detection sensor 28 that detects the rotational speed of the hydraulic motor 20 as a cutting driving speed detection unit that detects the driving speed of the cutting processing device 4. A travel speed detection sensor 26 serving as an actual travel speed detecting means for detecting the travel speed of the travel apparatus 1 and a cutting electric motor 29 for cutting and shifting that changes the discharge amount of the hydraulic pump 19 of the cutting transmission K are provided. ing.

As shown in FIG. 3, the traveling speed detection sensor 26 is a rotating body that rotates integrally with the traveling device 1 and is positioned on the lower transmission side of the auxiliary transmission means Sb, so that the shift gear 22 c in the auxiliary transmission means Sb can rotate integrally. The traveling speed of the traveling device 1 is detected by detecting the rotating shaft 23 that is slidably supported.
That is, although not described in detail, an unevenness detection sensor for detecting the unevenness of the detection body by attaching a detection body provided with unevenness on the outer peripheral portion to the rotating shaft 23 and fixedly installed corresponding to the outer peripheral portion of the detection body. And a calculation unit that obtains the number of times that the unevenness detection sensor detects a convex per unit time as the rotation speed of the detection body.

Then, based on the detection information of the traveling speed detection sensor 26 and the cutting speed detection sensor 28, the control means H as a shift control means controls the operation of the cutting electric motor 29 for the cutting speed as described below. It is configured.
That is, the drive command can be switched between a drive command state for instructing a drive command for driving the reaping processing device 4 at the set target drive speed M and a command release state for instructing a release command for releasing the drive command for the reaping processing device 4. In the state, a manually operated mowing drive command means J for commanding a speed index P indicating the level of the driving speed of the mowing processing device 4 is provided.

  When the release command is commanded by the cutting drive command unit J, the control unit H executes the travel linkage shift process, and when the drive command is commanded by the cutting drive command unit J, The linkage shift process is executed.

The control means H stops the cutting processing device 4 when the traveling device 1 stops and reverses in the traveling linkage shift processing, and travels the driving speed W of the cutting processing device 4 when the traveling device 1 moves forward. As the traveling speed V of the apparatus 1 increases, the cutting electric motor 29 is operated so as to shift the cutting transmission apparatus K so as to have a set relation speed (see FIG. 5) that is set to a higher speed.
In the present embodiment, since the traveling speed detection sensor 26 detects only the rotational speed of the rotary shaft 23 and cannot detect the rotational direction, the control means H uses the speed change operation lever 24. Using the detection information of the target speed detection sensor 25 that detects the operation position as the target travel speed Q, discrimination between forward and reverse is performed. Incidentally, a traveling speed detection sensor 26 that detects the rotational direction of the rotary shaft 23 is used, and the forward / backward determination is made based on the detection information of the traveling speed detection sensor 26. Of course, it may be.

  Further, when the traveling speed V detected by the traveling speed detection sensor 26 is zero, the control means H is based on the detection information of the target speed detection sensor 25 and the target traveling commanded by the shift operation lever 24. The travel linkage shift process is executed using the speed Q as the travel speed. That is, when the target travel speed Q corresponding to the operation position of the speed change operation lever 24 detected by the target speed detection sensor 25 corresponds to the forward movement, the drive speed W of the reaping processing device 4 becomes higher as the target travel speed Q becomes higher. The mowing electric motor 29 is operated so as to shift the mowing transmission device K so as to achieve a set relational speed (see FIG. 6) determined in relation to the higher speed.

  Incidentally, as shown in FIG. 5, the setting-related speed is such that the driving speed W is set to zero while the running speed V is increased from zero to the set low speed, and the driving speed is set when the running speed V becomes the set low speed. W is determined in the form of increasing to the set low speed, and as shown in FIG. 6, the relationship between the target traveling speed Q and the driving speed W is also determined in the same form. Can be variously changed, and the relationship between the target traveling speed Q and the driving speed W can be variously changed.

  Further, the control means H operates the reaping electric motor 29 to shift the reaping transmission device K so that the reaping processing device 4 is driven at the set target driving speed M in the unlinked shifting process, and As the set target drive speed M, as shown in FIG. 7, the culm is detected by the culm presence target speed M1 when the culm is detected by the cultivar sensor 50 and the cultivar sensor 50. The target speed M0 for cereal absence is not determined when the target speed M1 for cereal presence is set to be lower than the target speed M0 for cereal absence, The target speed M1 and the target speed M0 for cereal absence are made higher as the speed index P commanded by the cutting drive command means J is higher, and the speed when the speed index P is the same speed is set as the grain speed. The target speed M1 for the presence of potatoes It is configured to define a state which is a slower than use the target speed M0.

In other words, as shown in FIG. 4, the cutting drive command means J includes a neutral position T that is urged to return, a command operation tool 30 that can be moved to the side away from the neutral position T, and a command operation thereof. The position detection sensor 31 for detecting the position P of the tool 30 and the command control means 32 are configured.
The command operating tool 30 is constituted by a stepping operation type stepping pedal (see FIG. 4) provided in a position corresponding to the foot portion of the driver's seat 2 so as to return to the raised position as the neutral position T. The driver's foot seated in the driver's seat 2 can be stepped on. Specifically, it is provided at a location corresponding to the front of the right foot of the operator seated in the driver's seat 2, that is, at a location in front of the driver's seat 2 and closer to the right side.

  Based on the detection information of the position detection sensor 31, the command control means 32 issues a release command when the command operating tool 30 is positioned in the neutral operation area U on the neutral position side, and the command operating tool 30 is in the neutral operation area. When it is located in the command operation area G on the side farther from the neutral position T than U, a drive command is commanded. In addition, the command operating tool 30 becomes faster as it is located on the side farther from the neutral position T in the command operation area G. A speed index P is commanded.

  Then, as shown in FIG. 7, the speed index P commanded by the command control means 32 when the command operating tool 30 is positioned in the front range G1 on the neutral position side in the command operating range G. Based on the above, the culm presence target speed M1 and the culm absence target speed M0 as the set target drive speed M of the reaping processing device 4 are set to the set low speed, and the front range in the command operation range G Based on the speed index P commanded by the command control means 32 when the command operating tool 30 is positioned in the rear range G2 on the side farther from the neutral position T than G1, the set target drive speed of the cutting processing device 4 is set. In a form in which the culm presence target speed M1 and the culm non-existence target speed M0 as M are determined so as to gradually increase from the set low speed to the side where the command operation tool 30 is away from the neutral position T. And directive When the speed index P commanded by the control means 32 is the same, the target speed M1 for cereal presence is half the target speed M0 for cereal absence, The target speed M0 for cereal absence when the speed index P commanded by the control means 32 is maximum is the maximum among the driving speeds W of the reaping processing device 4 when it is assumed that the traveling linkage shift process is executed. The speed is lower than the maximum speed W1. Specifically, the speed is set to ½ of the maximum speed W1.

  The command control means 32 is configured using the control means H using the storage function and the discrimination function of the control means H. That is, the control means H determines whether a release command or a drive command is commanded based on the detection information of the position detection sensor 31, and additionally determines the speed index P.

  Incidentally, in the unlinked shift process, the set target drive speed M is the cereal presence target speed M1 and the cereal absence target speed M0, the cereal presence target speed M1 is the cereal absence target speed M0. By setting in a state where the speed is lower than that, when the harvested grain remaining in the grain transporting path of the harvesting processing device 4 is supplied to the threshing device 5, and entering the field at a traveling stop state or at a very low speed In each case, the harvesting processing device 4 can be driven satisfactorily.

In other words, the combine is in a stopped state or at a very low speed, such as when entering the field while sliding down the slope with the traveling device 1 stopped, or entering the field while traveling at a very low speed. In order to drive the harvesting processing device 4 that is not driven in the traveling linkage shift process or driven at an extremely low speed so as to appropriately cause the culm when entering the field, the harvesting drive command means J A drive command may be issued at
When the harvested cereal rice cake remaining in the harvesting processing device 4 is supplied to the threshing device 5, when the harvesting processing device 4 is greatly raised from the height of the harvesting near the ground, the threshing device 5 is removed from the harvesting processing device 4. In the short period until the cutting processing device 4 is greatly raised from the cutting height near the ground, that is, the cutting processing device 4 is close to the ground. In order to complete the supply of cereals to the threshing device 5 while located at the cutting height, it is desirable to drive the cutting processing device 4 at a fairly high speed. On the other hand, in the case of entering the field at a traveling stop state or at a very low speed, if the cutting processing device 4 is driven at a high speed, the inconvenience of causing the threshing due to the high speed action and the harvested cereals are leading the tip. As a result of being conveyed toward the threshing device 5 in a state, there arises a disadvantage that a conveyance trouble such as conveyance clogging occurs, so that it is desired to drive the cutting processing device 4 at a low speed.

  When the traveling device 1 is stopped or reversely driven, when the harvested corn straw remaining in the grain transportation route of the harvesting processing device 4 is supplied to the threshing device 5, it is driven by the reaping drive command means J. When the command is issued, the stock sensor 50 does not detect the culm, or even if it is detected, the cereal is not detected immediately after the cereal is conveyed. Therefore, the harvesting processing device 4 is driven at a higher speed for non-existence of grain culm M0, and the harvested sorghum remaining in the harvesting processing device 4 can be quickly supplied to the threshing device 5.

  Also, when the traveling device 1 is in a stopped state, when it enters the field while sliding down the slope, or when entering the field while traveling at a considerably low speed, it enters the field at a traveling stop state or at a very low speed. When approaching, when the drive command is commanded by the cutting drive command means J, the stock sensor 50 does not detect the kernel immediately after the drive command is issued. Although the reaping processing device 4 is driven at the non-existing target speed M0, the culm is reaped, and the culm is immediately detected by the stock sensor 50, and the cereal is not present. Since the harvesting processing device 4 is driven at the target speed M1 for cereal presence that is lower than the target speed M0, the inconvenience that threshing occurs due to the high speed action, and the culm that has been harvested is transferred to the threshing apparatus 5 in the tip leading state. Transport towards It is in, to suppress a disadvantage caused conveyance troubles such as conveyance jam, and that culms can satisfactorily cutting processing.

In addition, a command switch 35 is provided as an execution command means for selectively commanding a permission command for permitting the execution of the unlinked shift process and a stop command for stopping the execution.
When the permission command is instructed by the command switch 35, the control means H executes the non-associative shift process, and when the stop command is instructed by the command switch 35, the non-associative shift process is performed. It is configured not to run.

Next, a detailed description will be given of a cutting shift process for shifting the cutting transmission device K by the control means H based on the flowchart of FIG.
First, it is determined whether or not the mowing clutch 15 is engaged, that is, whether or not the clutch operating lever 44 is operated to the clutch engagement command position Y (# 1). When it is operated, it is determined whether or not the execution command state is commanded by the cutting auto command switch 48, that is, whether or not the cutting auto command switch 48 is turned on (# 2).
When the cutting auto command switch 48 is not turned on, and even when the cutting auto command switch 48 is turned on, when the cutting processing device 4 is below the set height, that is, when the cutting processing device 4 is being driven. In (# 3), it is determined whether or not a permission command is commanded by the command switch 35 (# 4). When the permission command is commanded, a drive command is commanded by the cutting drive command means J. Is determined (# 5).

When the permission command is instructed by the command switch 35 and the drive command is instructed by the cutting drive command means J, the set target driving speed set by the cutting drive command means J is set for the cutting processing device 4. The unlinked shift process for shifting the cutting transmission device K so as to drive at M is executed (# 7), and when the permission command is not commanded by the command switch 35 or when the cutting drive command means J is instructed. When the drive command is not commanded, the travel linkage shift process is executed (# 6).
As the traveling linkage shift processing, basically, the driving speed W of the cutting processing device 4 is increased as the traveling speed V of the traveling device 1 detected by the traveling speed detection sensor 26 increases. The cutting transmission device K is operated to shift to a predetermined set relationship speed. When the traveling speed V detected by the traveling speed detection sensor 26 is zero, the target speed detection sensor 25 detects the speed. When the target travel speed Q corresponding to the operation position of the speed change lever 24 corresponds to the forward movement, the driving speed W of the reaping processing device 4 becomes a set relational speed that is set so as to increase as the target travel speed Q increases. Thus, the cutting transmission K is shifted.

  Further, when it is determined that the clutch operation lever 44 is not operated to the clutch engagement command position Y (# 1), the cutting auto command switch 48 is turned on (# 2), and the cutting processing device 4 is set. When it is determined that the height is higher than the height (# 3), stop processing (# 8) for stopping the operation of the mowing electric motor 29 is executed.

[Another embodiment]
Next, another embodiment will be described.

(1) In the above embodiment, the control means H controls the operation of the travel electric motor 27 based on the detection information of the target speed detection means 25 that detects the target travel speed Q commanded by the travel speed change operation tool 24. Although a mode in which a traveling shift is performed by controlling is illustrated, the traveling shift operation tool 24 and the transmission means Z may be interlocked and connected using a mechanical linkage mechanism such as a link mechanism.

(2) Based on the speed index P commanded by the command control means 32, the culm presence target speed M1 and the culm absence target speed M0 as the set target drive speed M of the reaping processing device 4 are determined. The form can be variously changed in place of the form described in the above embodiment.
For example, as shown in FIG. 9, as in the above-described embodiment, the speed commanded by the command control means 32 when the command operating tool 30 is positioned in the front range G1 that is the neutral position side in the command operating range G. Based on the index P, the culm presence target speed M1 and the culm non-existence target speed M0 as the set target drive speed M of the reaping processing device 4 are set to the set low speed, and within the command operation range G Based on the speed index P commanded by the command control means 32 when the command operating tool 30 is positioned in the rear range G2 on the side farther from the neutral position T than the front range G1, the command operating tool 30 is moved to the neutral position T. When the speed index P commanded by the command control means 32 is the same, and the speed index P commanded by the command control means 32 is the same, the target speed M1 for cereal presence For non-existence of grains In the above-described embodiment, the target speed for the absence of cereal when the speed index P commanded by the command control means 32 is the maximum is determined. A mode in which M0 is set to a speed lower than the maximum speed W1 that is the maximum among the driving speeds W of the reaping processing device 4 when it is assumed that the traveling linkage shift process is executed, specifically, a mode in which the speed is set to ½ of the maximum speed W1. However, instead of this, it is assumed that the target speed M0 for cereal absence is when the speed index P commanded by the command control means 32 is the maximum, and the running linkage shift process is executed. Alternatively, it may be determined in the form of the same speed as the maximum speed W1 that is the maximum among the driving speeds W of the cutting processing device 4 in FIG.
(3) In the above embodiment and another embodiment of the above (2), when the speed index P commanded by the command control means 32 is the same, the culm presence target speed M1 is the grain Although the case where the speed is set to half the target speed M0 for non-existence of cocoons, the target speed M1 for cereal presence is set to 3/4 of the target speed M0 for non-existence of pestle, or 1 It can be variously changed how much the target speed M1 for cereal presence is reduced from the target speed M0 for cereal non-existence.

(4) In the above embodiment and another embodiment of the above (2), the target speed M1 for cereal presence is uniformly set over the entire range of the speed index P commanded by the command control means 32. The case where the speed is set to half the target speed M0 for cereals non-existing is exemplified, but for example, in the range on the high speed side compared to the low speed side range of the speed index P, the target speed M1 for cereal present The mode in which the target speed M1 for cereal presence is lower than the target speed M0 for cereal absence can be changed in various ways.

(5) In the above embodiment, the step pedal is illustrated as the command operation tool 30, but the operation lever is provided at the front part or the lateral part of the driver's seat 2 and can be moved and operated in the front-rear direction and the lateral direction. Although the command operation tool 30 may be configured, it is more convenient on the operation surface to configure the command operation tool 30 with a stepping pedal.

(6) In the above embodiment, the speed change means Z for changing the travel speed of the travel device 1 and the drive speed of the harvesting processing device 4 from the travel transmission device S and the harvesting transmission device K connected in parallel to the engine 10. For example, the output of the traveling transmission device S connected to the engine 10 is branched to drive the cutting processing device 4, and the cutting processing device 4 is driven by power from the traveling transmission device S. When driving at a higher speed than the driven speed, various configurations can be used for the transmission means Z, such as a configuration in which the cutting processing device 4 is driven by an electric motor while being separated from the traveling transmission device S. it can.

(7) In the above embodiment, as the setting-related speed in the traveling linkage shift process, the cutting processing device for the change amount of the driving speed W of the cutting processing device 4 with respect to the unit variation amount of the traveling speed V and the unit variation amount of the target traveling speed Q. 4 and FIG. 6 exemplify the case where the amount of change in the driving speed W is the same in the entire range of change in the traveling speed. However, the unit variation in the traveling speed V and the target traveling speed Q is exemplified. The amount of change in the driving speed W of the reaping processing device 4 with respect to the above may be increased or decreased as the traveling speed V or the target traveling speed Q increases. Various setting speeds with the driving speed W of the processing device 4 can be changed.

(8) In the above embodiment, the rotating shaft 23 that rotates integrally with the shift gear 22c of the auxiliary transmission means Sb is exemplified as the rotating body that rotates integrally with the traveling device 1 that the actual traveling speed detecting means 26 detects. The rotating body on which the speed detecting means 26 detects can be changed as long as it rotates integrally with the traveling device 1. Incidentally, the integral rotation with the traveling device 1 is only required to rotate in synchronization with the traveling device 1 when the traveling device 1 moves forward and backward.
In addition, various configurations can be used as the configuration of each unit necessary for carrying out the present invention.
