[0001]

[Industrial applications]

 The present invention relates to a control device mounting structure for a mobile work vehicle such as an agricultural tractor or a rice transplanter.

[0002]

[Prior Art]

 Conventionally, the working condition of a mobile work vehicle such as an agricultural tractor or a rice paddy planter has been changed to the working state (such as a rotary tiller and plow for a tractor, a planting unit, a sowing unit, and a fertilizer unit for a passenger rice planter). Based on the detection signal from the sensor or switch to detect, the actuators (such as solenoid valves) of each part of the machine are controlled by the control unit consisting of a microcomputer and the working unit is set to the proper working condition corresponding to the field conditions. The control device adapted to automatically control the above is already known and put into practical use.

[0003]

[Problems to be solved by the device]

 However, there is a problem in the mounting structure of each part of the conventional control device of this type in the mobile work vehicle to the machine body. That is, for example, in a tractor having various control functions such as position control, automatic plowing depth control, and automatic tilt control, the position lever, the plowing depth setting means, the tilt setting means, the sensitivity switch, etc. are mainly operated during driving work. Locate the necessary operation parts, the adjustment part with the adjustment function accompanied by the program change such as mode change and tire size change, and the control related parts of the control part such as the microcomputer, etc. by finding suitable mounting spaces and separate them. Since the parts are placed in different places, the layout of each part is not neat and the appearance is complicated, and the wiring work during assembly is troublesome, and a special cover for waterproofing, dustproofing, etc. In addition to the above, there is a problem that the adjustment unit is erroneously operated during operation when the adjustment unit is exposed to the outside.

[0004]

Means for Solving the Problems The present invention was conceived based on the above situation, and based on a detection signal from a sensor or a switch that detects the working state of the working unit, a control unit is used. In a mobile work vehicle in which the actuators of various parts of the machine body are automatically controlled, an operation part that requires operation mainly during driving work is provided at a position where it can be operated in the sitting posture between the driver's seat and the fender. The gist is that a side panel is provided, and an adjusting section having an adjusting function such as program switching and a control section are provided below the driver's seat.

[0005]

[Action]

 Due to the above-mentioned configuration of the present invention, the operation section that is always used during work is exposed in the driver's seat space, and the other adjusting section and control section are hidden under the driver's seat, so the layout of control-related parts Is clean and eliminates the complexity of the appearance, and the operation part is protected from the left and right by the fender and the driver's seat, so damage due to abutment can be prevented.
