DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a plurality of manual switches for instructing command information for executing operation control of a plurality of working units, and controls the operation of each of the plurality of working units by the plurality of manual switches. Control means for managing which one of the manual switches is to be executed based on the command information from the manual switches, and executing operation control for each of the plurality of working units based on the command information from the plurality of manual switches. To a control device for a working machine.

[0002]

2. Description of the Related Art In a work machine control device described above, a plurality of manual switches and manual operation levers for instructing command information for executing operation control of a plurality of work units are provided by a driver operating the work machine. It is arranged so that it can be concentrated at the driver's hand position. Hereinafter, a combine as a working machine will be described as an example.

[0003] In the combine, a mowing part as a working part is attached to the front part of the fuselage so as to be able to swing up and down by a hydraulic cylinder. The operation lever is provided in a state where it is biased to return to the neutral position. When the manual operation lever is operated to the rear of the fuselage, the raising of the reaper is commanded, and when the manual operation lever is operated to the front of the fuselage, the lowering of the reaper is commanded, and the manual operation lever is neutralized. When it has returned to the position, commands are issued to stop the raising and lowering of the reaping unit. Based on these commands, the hydraulic cylinder is extended and retracted to control the reaping unit to perform the raising and lowering operation. Further, the manual operation lever for mowing up and down is provided with an automatic up and down switch which can be operated by a finger holding the grip portion. Then, for example, at the start of the reaping operation, when the reaping unit is raised to the upper limit position, by pressing the automatic lifting switch, the reaping unit can be automatically lowered to the lowering target position, for example, At the end of the reaping operation, control is performed such that the reaping unit can be automatically raised to the upper limit position by pressing the automatic lifting switch.

Further, in the above combine, a body is provided with a pair of left and right crawler traveling devices as a working unit, and a hydraulic pressure is transmitted to the driving unit by shifting the power from the power unit to each of the left and right traveling devices. A manual operation lever for instructing a shift command for shifting a continuously variable transmission of a type in a forward direction and a reverse direction is provided so as to be swingable in the longitudinal direction of the machine. In other words, when the gearshift manual operation lever is operated from the neutral position to the forward side of the fuselage, the speed is increased to the forward side, when it is operated from the neutral position to the rearward side of the fuselage, the speed is increased to the reverse side, and when the lever is returned to the neutral position, the traveling stop state is established. It is controlled so that

[0005] The grain stalks cut by the cutting section are conveyed to a threshing section as a working section for threshing, and the culm length of the culms to be conveyed is transferred to the culm transfer section to the threshing section. A tip sensor for detecting the tip is provided, and based on the detection information of the tip sensor, a handling depth adjusting means for adjusting a handling depth in the threshing unit is operated to automatically adjust to a proper handling depth state. Handling depth control is being performed. Further, a handle depth adjustment for manually adjusting the handle depth adjusting means to the shallow handle side and the deep handle side, respectively, in a state in which the shift operation lever can be operated by the finger holding the grip portion. Manual switch. It should be noted that which of the handling depth control based on the detection information of the tip sensor and the manual handling depth adjustment operation by the manual switch is executed is switched by the switching information from the changeover switch.

Conventionally, as described above, the operation control of each of a plurality of working units such as a mowing unit and a threshing unit is performed based on command information from one of the plurality of manual switches. Was set and managed uniquely. For example, the automatic raising and lowering operation for automatically raising and lowering the mowing unit between the upper limit position and the lowering target position is executed based on command information from an automatic raising and lowering switch provided on a manual operating lever for mowing and lowering, and threshing. The manual operation for adjusting the operating depth for manually adjusting the operating depth of the section is set so as to be executed based on command information from an operating switch for adjusting the operating depth provided on the manual operation lever for shifting.

[0007]

As described above, the various types of manual switches have been concentrated on the driver's hand position, but the driver's proficiency with the machine, age, gender, etc. Due to the condition (1), it is not possible to determine unconditionally where to position each of the above manual switches. However, in the above-described related art, the correspondence relationship regarding whether to perform the operation control of each of the plurality of working units based on the command information from any of the manual switches is uniquely set. There was a problem that the manual switch had to be operated in a state where the operability was poor.
