If the pre-cutting processing unit 10 is irradiated in the upward direction of the airframe and the pre-cutting processing unit 10 is in the descending work state, the light irradiated in the forward direction of the self-propelled airframe by the lower reflector 25b becomes light parallel to or close to the ground. Set to reflection characteristics Are you.

  The reflection characteristics of the two types of reflector portions 24a and 24b of the upper headlamp 22 are reflected from the bulb 28 of the upper headlamp 22 and reflected by the inner reflector portion 24a of the two types of reflector portions 24a and 24b. The light radiated in the forward direction of the traveling body is irradiated in the irradiation direction almost immediately before, and the front is irradiated slightly outside the lateral side of the traveling body of the pre-cutting processing unit 10 in the lateral direction, and the upper front side. The light emitted from the bulb 28 of the illumination lamp 22 and reflected by the outer reflector 24b of the two types of reflectors 24a and 24b and emitted toward the front of the self-propelled aircraft is more self-propelled than the direction of irradiation by the inner reflector 24a. The reflection characteristics are set so that the light is irradiated in the inward irradiation direction in the lateral direction of the airframe.

  As shown in FIGS. 9 and 10, an upward reflecting tongue 25d is provided at the lower part of the reflector members constituting the reflectors 24 and 25, and the upward reflecting tongue 25d In a state where a part of the light is reflected upward from the direction of reflection by the reflectors 25a and 25b and the pre-cutting processing unit 10 is raised to the non-working state, a part of the light from the bulb 29 is directed to the oncoming vehicle. It is made not to irradiate towards.

  As shown in FIG. 1, the headlamp device 20 is assembled so that the optical axis 29a of the bulb 29 of the lower headlamp 23 passes through the tip 12a of the weeding tool 12 located at the most lateral end.

  In the left headlamp device 20, as shown in FIG. 7, the valves 28 and 29 of the upper headlamp 22 and the lower headlamp 23 are inclined at about 15 degrees with respect to the front-rear direction of the self-propelled aircraft. A is supported in a mounting posture inclined leftward and outward at A. Although not shown, in the right headlamp device 20, the bulbs 28 and 29 of the upper headlamp 22 and the lower headlamp 23 are positioned at a right angle of about 15 degrees with respect to the front-rear direction of the self-propelled aircraft. It is supported in a mounting posture inclined laterally outward.

  As shown in FIG. 1, side lighting 40 is provided on the lateral side farther from the driving unit 3, on both lateral sides of the pre-cutting processing unit 10.

  As shown in FIG. 8, the side lamp 40 is fixed to the side cover 30 by being arranged in a side lamp assembly recess 34 provided with a through hole in the side plate portion 32 of the side cover 30.

  2 shows the irradiation range by the side lamp 40, and FIG. 2 shows a plan view of the self-propelled aircraft irradiated by the left and right headlamp devices 20 when the pre-cutting processing unit 10 is lowered to the lowering work state. 6 (a) shows the irradiation range in a side view of the self-propelled aircraft that the left and right headlamp devices 20 irradiate when the pre-cutting processing unit 10 is lowered to the descending work state. FIG. 6B shows the irradiation range in the side view of the self-propelled aircraft that the left and right headlamp devices 20 irradiate when the pre-cutting processing unit 10 is raised to the lifted non-working state that has been raised to the stroke end. When the harvesting operation is performed, the mowing pretreatment unit 10 is lowered to the lowering operation state even at night, and therefore the upper headlamp 22 and the lower headlamp 23 of the left headlamp device 20 are used. Of the weeding tools 12 arranged in the lateral direction of the vehicle body, the vehicle body left lateral outermost The upper headlamp 22 of the right headlamp device 20 is irradiated while irradiating the front end portion of the weeding tool 12 and the irradiation range LD that irradiates the left lateral outer side of the weeding tool 12 and the front ground. And the lower headlamp 23, the distal end portion of the weeding tool 12 located on the outermost right side of the weeding tool 12 among the weeding tools 12 arranged in the lateral direction of the car body, and the right lateral outer side of the weeding tool 12, The work can be performed while irradiating the irradiation range RD for irradiating the front ground. At this time, pre-cutting processing is also performed by illumination in the illumination range S by the side lamp 40 in addition to the illumination of the self-propelled vehicle body laterally outward by the upper head lamp 22 and the lower head lamp 23 of the left head lamp device 20. Illuminating the uncut grain halves near the lateral end of the section 10, in particular, illuminating the vicinity of the roots of the uncut grain cereals, makes it easy to align the weeding tool 12 with the uncut grain culms.

When traveling in a non-working state such as on the road, the upper headlight of the left headlight device 20 is raised by raising the pre-cutting processing unit 10 to the stroke non-working state even at night. The lamp 22 and the lower headlamp 23 irradiate an irradiation range LU that irradiates the ground surface farther away from the self-propelled aircraft than the irradiation range LD when the pre-cutting processing unit 10 is in the descending work state. However , the upper headlamp 22 and the lower headlamp 23 of the right headlamp device 20 move forward from the self-propelled aircraft relative to the irradiation range RD when the pre-cutting processing unit 10 is in the lowering work state. It is possible to travel while irradiating an irradiation range RU that irradiates on a remote ground. At this time, it is possible to travel while illuminating the front so that the oncoming vehicle is less likely to be dazzled by the upward reflection by the upward reflection tongue 25d.

In both the left and right headlamp devices 20, as shown in FIG. 5, both the upper headlamp 22 and the lower headlamp 23 raise the stems and are self-propelled from the front surface 13c of the raising case 13b of the device 13. The outer surfaces of the lenses 21 of both headlamps 22 and 23 are raised so as to be in a state of being moved backward by a backward difference B toward the rear side of the machine body, and slightly backward from the front surface 13c of the case 13b. Thus, the headlamp device 20 is assembled in the headlamp device assembling recess 33. 4 and 5, when the forced weeding device 50 is mounted on the front side of the stalk raising device 13 located at the most lateral end as shown by a two-dot chain line, the headlamp device 20 is unlikely to become an obstacle. Thus, the forced weeding device 50 raises the stem and raises the device 13 so as to approach the front surface 13c of the raising case 13b and easily follow it.
The forced weeding device 50 divides the planted cereals into a cutting target and a non-cutting target by the weed claw 52 that moves upward from the weeding case 51 in a state of protruding to the front side of the self-propelled aircraft.

  As shown in FIGS. 1 and 3, the left and right lateral covers 30 can be easily detached by simply switching the pair of catchers 35 between the engaged state and the disengaged state. The lower cover 30a and the lower cover 30a are separate parts, and the upper cover 30b includes the headlight device 20 and the sidelight 40.

  As shown in FIGS. 9 and 13, the concave portion 60 located on the back side of the forward concave portion 60 a into which the reflector 25 of the lower headlamp 23 enters the back side of the headlamp case 20 a, and the reflector 24 of the upper headlamp 22. Is provided with a pair of mounting legs 62 and 62 projecting in a state of being arranged in the vertical direction of the headlamp device with one recess 61 interposed therebetween.
