  As shown in FIG. 4, the headlamp 27 includes a headlamp reflector 51 (a reflecting mirror for the headlamp 27) and a light bulb support 52 that is located at the bottom (back bottom) of the headlamp reflector 51. The headlamp bulb 53 is supported, and a headlamp lens 54 is mounted on the front portion of the headlamp reflector 51. The headlamp lens 54 is formed in a substantially rectangular shape when viewed from the front, and the headlamp 27 is arranged so that the headlamp lens 54 is substantially perpendicular to the ground surface. The upper end portion of the headlamp 27 slightly protrudes from the front irradiation opening 40 inclined backward, and the front irradiation cover 41 that covers the headlamp 27 so that the upper end portion of the headlamp 27 does not come into contact therewith. Is formed in a rounded convex shape.

  Further, as shown in FIGS. 5, 13 and 14, a side irradiation opening 42 for the substantially trapezoidal work lamp 28 is formed in the side portion of the light housing 39R / 39L. A work lamp 28 is disposed in the opening 42. The work lamp 28 is formed along the shape of the substantially trapezoidal side irradiation opening 42, and a work lamp reflector 55 having a recess 59 in the center, and a light bulb positioned on the side of the work lamp reflector 55. The work lamp bulb 57 supported by the support 56 and the work lamp lens 58 mounted so as to cover the recess 59 of the work lamp reflector 55 are configured.

  As shown in FIGS. 12 to 14, the work lamp lens 58 is detachably fitted to the locking portion 55 a of the work lamp reflector 55. A locking piece 55b and a protruding piece 55c are formed on the back side of the work lamp reflector 55. The locking piece 55b is detachably locked to the locking recess 73 of the light housing 39R / 39L. Further, the projecting piece 55c is detachably fastened to the fastening frame portion 74 of the light housing 39R / 39L with a bolt 75. That is, the work lamp reflector 55 is fastened to the light housings 39R and 39L by the bolts 75 in a state where the work lamp reflector 55 is locked to the light housings 39R and 39L via the locking pieces 55b. As a result, the work lamp reflector 55 can be fixed to the light housings 39R and 39L by one bolt 75.

  As shown in FIGS. 4, 11, and 14, the headlamp 27 is centered on a pivot shaft 44 having an axis in the left-right direction, and the light irradiation direction from the headlamp 27 is in the vertical direction. It is provided so as to be able to swing. A balance weight 46 is connected to the headlamp 27. In conjunction with the lifting and lowering operation of the mowing device 4, the headlamp 27 rotates around the rotation support shaft 44, and the irradiation direction of the light from the headlamp 27 swings in the vertical direction. Is configured to be held while being held substantially constant with respect to the horizontal.

  As shown in FIGS. 11 and 14, the light installation base 80 is fixed to the inner surfaces of the side covers 35R and 35L by welding. Further, a headlamp support frame 81 is disposed on the headlamp reflector 51. The headlamp support frame 81 is brought into contact with the light installation base 80 by inserting the headlamp support frame 81 so as to be able to enter and exit from the outer surface of the side covers 35R and 35L through the insertion port 82. In this state, a pivot support pipe 45 provided on the headlamp support frame 81 is rotatably fitted on a rotation support shaft 44 provided on the light installation base 80. That is, a pivot pipe 45 is provided in the left and right horizontal direction at the rear end portion of the headlamp 27, and the pivot pipe 45 is arranged in the horizontal direction on the side covers 35R and 35L for fixing the light housings 39R and 39L. It is externally fitted to a rotation support shaft 44 fixed to the shaft and is rotatably supported. Further, a light bulb support 52 and a balance weight 46 protruding downward are fixed to the pivot pipe 45. The balance weight 46 is heavier than the bulb support 52 and the headlamp bulb 53.

  In such a configuration, when the reaping device 4 is moved up and down, the balance weight 46 tends to be positioned vertically below the rotation support shaft 44 due to its gravity, and the balance weight 46 and the headlamp 27 (the headlamp bulb 53) are It rotates around the rotation support shaft 44 in conjunction with the lifting operation of the reaping device 4. At this time, the headlamp 27 is held at a constant angle with respect to the horizontal plane.

  With this configuration, the headlamp 27 maintains a predetermined angle and maintains a desired angle regardless of the adjustment of the lifting position of the cutting device 4 even when turning while raising the cutting device 4 on a headland or the like. Since the position can be reliably irradiated, it is possible to ensure good operability and safety.

  In addition, the headlamp 27 may vibrate due to driving of the engine 10, the cereal conveyance mechanism 33, or the like during traveling or work, and the irradiated portion may vibrate and become difficult to see. In addition, when traveling on a sloping ground, the irradiation direction may be too high or too low, so the actuator 47 serving as a light lock means that stops swinging except when the mowing part is raised or lowered is pivoted. It is arranged in the vicinity of the support pipe 45.

  That is, the light lock means includes a friction pad 49 and an actuator 47 that presses the friction pad 49 against the pivot pipe 45. The actuator 47 includes a cylinder, a motor, a solenoid, and the like and is connected to the control device 25. In this embodiment, when the actuator 47 is operated, the piston 48 is extended to press the friction pad 49 toward the pivot pipe 45 and is fixed so as not to rotate with respect to the light housings 39R and 39L. However, the configuration of the light lock means is not limited, and may be a configuration in which the balance weight 46 is fixed.

  Thus, when the headlamp 27 is turned on by operating the headlamp switch 23, the light lock means is activated, and the headlamp 27 is fixed and cannot swing. In this state, when the cutting unit lifting switch 19 is operated, the light lock means is released and the headlamp 27 becomes swingable, and the headlamp 27 moves in a predetermined direction in accordance with the lifting operation of the cutting device 4. It turns to face. When the mowing unit lifting / lowering switch 19 is not operated, the light lock means is activated and the headlamp 27 is fixed. Thus, the headlamp 27 is controlled so as to always face a predetermined direction with a simple configuration.

  However, instead of providing the light lock means, the headlamp 27 is configured to be rotatable about a rotation support shaft 44 by a motor, and the elevation angle of the reaping device 4 is detected by a sensor so that the reaping device 4 is raised and lowered. When it is rotated, the headlamp 27 can be configured to illuminate a predetermined direction by driving a motor in accordance with the rotation.

  Since the work lamp 28 is attached to the side surface, the irradiation direction hardly changes even when the reaping device 4 is moved up and down.

  As described above, the harvesting device 4 disposed so as to be able to move up and down in front of the airframe is combined with the headlamp 27 that illuminates the front of the airframe and the work light 28 that illuminates the front side of the mowing device 4. 27, the work light 28, and the road running detection means 22 are connected to the control device 25, and when the road running state is detected with the headlamp 27 and the work light 28 turned on, the work light 28 is turned off. Therefore, the work lamp 28 can illuminate the front side of the reaping device 4, and the work can be easily performed at dusk or at night. Since the work lamp 28 is automatically turned off when traveling on the road, it is not dazzling even if it is located on the side, and the surroundings are not adversely affected. Moreover, useless energy consumption can be prevented.

  Further, when the work clutch 63 is provided between the engine 10 and the work machine (the reaping device 4 and the threshing device 5), the work clutch 63 is disconnected, and the traveling speed becomes equal to or higher than the set speed, the control is performed. Since the device 25 determines that the vehicle is traveling on the road, the vehicle traveling state can be reliably detected and does not light up when unnecessary.

  Next, the structures of the left and right lights 36R and 36L according to the second embodiment of the present invention will be described in detail with reference to FIGS. As shown in FIGS. 15 and 16, the light housings 39 </ b> R and 39 </ b> L include an engagement notch 101 into which the work lamp lens 58 and the front end side of the work light reflector 55 (the front end side 28 a of the work light 28) are fitted, And a lock lever body 102 that elastically presses on the outer surface of the rear end side of the reflector 55 (the rear end side 28b of the work lamp 28). The work light reflector 55 also includes a portable handle 103, a power plug 106 for connecting the input terminal 105 of the power cable 104 for the work light bulb 57, a battery 107 for the work light bulb 57, and a power source for the battery 107. And a power switch 108 for turning on / off the work lamp bulb 57.

  With the above configuration, as shown in FIG. 15, the power plug 106 fitted with the input terminal 105 is mounted with the work lamp 28 fixed to the light housings 39 </ b> R and 39 </ b> L by the engagement notch 101 and the lock lever body 102. The work light bulb 57 is connected to the control device 25 by connecting the power cable 104 to the work light bulb 57, and the work light bulb 57 is turned on / off by the on / off operation of the work light switch 24. When the work light bulb 57 is connected to the control device 25 via the power cable 104, the battery 107 is charged.

  On the other hand, as shown in FIG. 16, the operator releases the engagement of the lock lever body 102 from the outside of the side covers 35R and 35L, removes the work lamp 28 from the light housings 39R and 39L, and holds the handle 103. By carrying the work light 28, the work light 28 can be used as a portable lighting device such as a flashlight. When the work light 28 is removed from the light housings 39R and 39L, the work light bulb 57 is turned on / off by using the battery 107 as a power source by turning the power switch 108 on and off.

  Next, the structure of the left and right lights 36R and 36L according to the third embodiment of the present invention will be described in detail with reference to FIG.
