2. Description of the Related Art Generally, in an agricultural machine for performing agricultural work, a plurality of changeover switches arranged on a control panel are used to perform a series of different operations in order to perform a series of agricultural work with a single agricultural machine for the purpose of improving work efficiency. It is known that the contents are configured to be multi-functional. However, if it is inevitable to increase the number of changeover switches when changing the contents of multifunctional work as described above, the burden on the operator increases and the operation of the changeover switches is erroneously performed. On the other hand, it is easy to induce a decrease in the quality of work and a decrease in efficiency in evasive farm work.In particular, in the case of a mobile agricultural machine that performs farm work while traveling in a field, the worker can perform various work contents while performing driving operations. Since it is necessary to switch properly, not only will the frequency of erroneous operations increase, but it will also result in the erroneous operation of driving operations during aircraft travel, resulting in safe driving as well as prevention of erroneous operations by workers. There was a longing for the placement of the switch.

[0003]

SUMMARY OF THE INVENTION The present invention was conceived in view of the above situation, and its purpose is to accurately control work contents without inducing an erroneous operation by an operator. It is an object of the present invention to provide an arrangement structure of changeover switches in an agricultural machine which can be changed over, inform the operator of the changed control contents intuitively and hierarchically, and can smoothly perform a series of agricultural work.

[0004]

In order to solve the above problems, the technical means adopted by the present invention are different main controls such as cutting height control, cutting depth control, sorting control, direction control and horizontal control. A first group of change-over switches for changing modes are arranged horizontally in parallel above a control panel provided on one side of a driver's seat in an inclined shape, and mode switching of sub-control modes under each of the main control modes is performed. The second changeover switch group for performing the above is arranged hierarchically in a required number in series below the first changeover switch group thus arranged.

[0005]

Therefore, according to the present invention, when the work content is switched as the agricultural work progresses, the worker can appropriately switch from the current work content to the work content following the work content, and at a glance of the control panel. It is possible to easily and intuitively grasp the work status in a simple and hierarchical manner, and even when switching farm work while operating it like a mobile farmer, it is possible to suppress erroneous operation of the changeover switch as much as possible and smooth it. Agricultural work can be performed.

The lamp 24c in 3 is also turned off to disable the standard / moderate mode switching.

In the above-described structure, when performing a cutting and threshing work, when a start switch (not shown) is turned on, the combine 1 is set to the automatic control mode for each work content, and the first switching on the control panel 17 is performed. All the switch groups A are kept in the valid state, and the second changeover switch groups B are all in the invalid state, that is, [rice / wheat] 24 is the rice harvesting selection mode, and [standard / middle split] 23 is the standard (article). It is kept in the cutting mode. Then, in the above-mentioned initial setting state, when the target to be cut and threshed is wheat, the lamp 24c is operated by pressing the [rice / wheat] 24 on the control panel 17 while the [selection automatic] 20 remains ON. It lights up and switches to the wheat mowing selection mode, and the control signal for changing the mowing condition sent from the control unit uniformly drives the selection fins of the rocking flow plate (not shown) of the threshing unit 10, so that the gaps between the fins are formed. The optimum conditions for threshing of wheat are automatically adjusted.

Further, when performing the middle splitting in the field, when the [Direction / middle split] 23 is pressed with the [Direction automatic] 19 enabled, the lamp 23c lights up, and the rightmost direction with respect to the machine traveling direction. This is the so-called split-direction automatic control mode, which is based on the grain culling body 4. Then, when it becomes necessary to perform ridges, diagonal cutting, etc., the automatic direction control is canceled by turning off [Direction automatic] 19, and along with this, [Standard / middle split] 23 is also a normal standard (article). After returning to the cutting mode, the lamps 19c and 23c corresponding to the [direction automatic] 19 and the [standard / middle ratio] 23 are turned off.

The second changeover switch group B for changing over the mode of the sub-control mode of [standard / middle ratio] 23 and [rice / wheat] 24 by the switch operation on the control panel 17 is the above-mentioned [Automatic direction] of changeover switch group A of 1
9 and [automatic sorting] 20 are arranged in series in a hierarchical manner, so that the operator can operate other levers or operate the machine in parallel while performing agricultural operations. Even in a complicated work operation environment such as switching, the working state can be easily grasped intuitively and hierarchically by just glancing at the control panel 17, and the first switching switch group A and it are linked to this. It is possible to suppress an erroneous operation of switching with the second changeover switch group B as much as possible and perform a smooth agricultural work.

When the switch 19a of the [direction automatic] 19 is turned off when the switch 3 is in the mode automatic switching control mode of the middle division, even if the switch 23a is in the closed state, it is switched to the default standard (row cutting) mode. However, the present invention is not limited to this, and as shown in FIG. 4B, the [direction auto] 19 and the [standard / middle ratio] 23 may be configured as independent control circuits.

[0016]

In summary, according to the present invention, the first changeover switch group for changing over different main control modes such as cutting height control, handling depth control, sorting control, direction control and horizontal control is provided on one side of the driver's seat. The second changeover switch group, which is arranged horizontally in parallel above the control panels provided in the inclined direction toward one side, and which performs mode changeover of the sub-control mode under each of the main control modes described above, is arranged in the first group. Since only the required number of switches are arranged in a hierarchical hierarchy below the changeover switch group, even if the number of changeover switches is inevitably increased when changing the contents of multifunctional work, the operator can intuitively understand the changed control contents. In addition, it can be perceived hierarchically and can suppress erroneous operation of the changeover switch as much as possible, and it is suitable for agricultural work with mobile agricultural machinery that requires workers to appropriately switch various work contents while operating. Even if it is, it is possible to accurately perform the driving operation and the switching control according to the work content in the airframe traveling without inducing an erroneous operation, and it is possible to smoothly perform a series of agricultural work, which is a very useful novelty. It is effective.
