In the second aspect of the invention, the pre-harvest processing unit is connected to the front part of the self-propelled machine body so as to be swingable up and down in a descending working state and an ascending non-working state. The right headlight device for irradiating the outer side is fixed to the right lateral outer side of the pre-harvest processing unit. The headlamp device includes a first headlamp and a second headlamp whose irradiation direction is lower than that of the first headlamp, and the first headlamp is arranged above the second headlamp. Constitute. When the pre-harvest processing unit is in the descending working state, the headlamp device irradiates the ground in front of the weeding tool of the pre-harvest processing unit, and when the pre-harvest processing unit is in the non-working state, the pre-harvest processing The irradiation direction of the headlamp device is set so that the headlamp device irradiates the ground farther away from the self-propelled aircraft than when the unit is in the lowering work state.

In the third aspect of the invention, the pre-harvest processing unit is connected to the front part of the self-propelled machine body so as to be swingable up and down in a descending working state and an ascending non-working state. The left headlight device that irradiates the outer side is fixed to the left lateral outer side of the pre-harvest processing unit. The headlamp device includes a first headlamp and a second headlamp whose irradiation direction is lower than that of the first headlamp, and the first headlamp is arranged above the second headlamp. Constitute. When the pre-harvest processing unit is in the descending working state, the headlamp device irradiates the ground in front of the weeding tool of the pre-harvest processing unit, and when the pre-harvest processing unit is in the non-working state, the pre-harvest processing The irradiation direction of the headlamp device is set so that the headlamp device irradiates the ground farther away from the self-propelled aircraft than when the unit is in the lowering work state.

In the fourth aspect of the invention, the pre-harvest processing unit is connected to the front part of the self-propelled machine body so as to be swingable up and down in a descending working state and an ascending non-working state. The right headlight device that illuminates the outer side is fixed to the right lateral outer side of the pre-harvest processing unit, and the left headlight device that irradiates the front and left lateral outer side of the pre-harvest processing unit, Secure to the left lateral outside of the pre-harvest processing section. The headlamp device includes a first headlamp and a second headlamp whose irradiation direction is lower than that of the first headlamp, and the first headlamp is arranged above the second headlamp. Constitute. When the pre-harvest processing unit is in the descending working state, the headlamp device irradiates the ground in front of the weeding tool of the pre-harvest processing unit, and when the pre-harvest processing unit is in the non-working state, the pre-harvest processing The irradiation direction of the headlamp device is set so that the headlamp device irradiates the ground farther away from the self-propelled aircraft than when the unit is in the lowering work state.

That is, when the pre-harvest processing unit is lowered to the lowered work state, the headlamp device irradiates the ground in front of the weeding tool to set the irradiation direction of the headlamp device, and the pre-harvest processing unit is lifted non-working When the headlight device is raised to the state, the headlight device irradiates on the ground farther forward than when the pre-harvest processing device is in the lowering work state by setting the irradiation direction of the headlight device. When the work is in the lowering work state or in the non-lifting work state, the ground surface in front of the weeding tool is illuminated so that the desired ground surface is illuminated. The situation can be made easy to see, and when traveling, the ground on the front is illuminated more than at the time of work, so that the traveling destination can be seen easily.
An illumination range necessary for work or movement is illuminated by a headlamp device composed of a first headlamp and a second headlamp having different irradiation directions, and is composed of one of the headlamps. Compared to being illuminated by the device, it is illuminated brightly over the entire illumination range.
Since the first headlamp is located on the upper side of the body of the pre-harvest processing unit with respect to the second headlamp, the first and second headlamps are compared to those in which both headlamps are arranged in the lateral direction of the body. The first and second headlamps can be installed while reducing the space in the lateral direction of the aircraft necessary for installation.
When the second headlamp whose direction of irradiation is downward is arranged on the upper side of the machine body from the first headlamp, the second headlamp is designed so that the front of the weeding tool can be irradiated by the second headlamp. Needs to protrude from the first headlamp to the front side of the fuselage, and the front side of the headlamp device becomes uneven as viewed from the side of the fuselage. On the other hand, since the first headlamp having the upward illumination direction is positioned above the fuselage with respect to the second headlamp, the second headlamp projects forward of the fuselage from the first headlamp. Instead, the front of the headlamp device can be irradiated in front of the weeding tool while the front surface of the headlamp device becomes a flat surface or a state close thereto.

Therefore, according to the first to fourth inventions, even in the nighttime, it is easy to see the situation in the vicinity of the weeding tool so that the weeding tool can be adjusted to the desired position and operating state. In addition, the work can be adjusted with high precision, and even when the pre-harvest processing unit is raised to a non-working state, the vehicle can move and travel more easily on the ground surface than when working.
According to the first to fourth aspects of the present invention, the ground surface is brightly illuminated, and it is easier to see the situation of the destination and to perform work and movement more easily.
According to the first to fourth aspects of the invention, the front of the weeding implement is brightly illuminated by the first and second headlamps, but the headlamp device is installed in a small installation space in the lateral direction of the fuselage. It can be arranged in a compact manner, and can be obtained in a simple state in which the front side of the headlight device is a flat surface or a state close to it in a side view of the fuselage.

In the fifth aspect of the present invention, in the configuration of any one of the first to fourth aspects of the present invention, both the first headlamp and the second headlamp are turned on, and the first headlamp is turned off. However, it is configured to be switchable to a one-lamp state in which the second headlamp is lit.

  That is, when the pre-harvest processing unit is in the up non-working state, it is easier to irradiate the oncoming vehicle with the first headlight and the second headlight facing upward than in the down work state. . At this time, when switching to the one-lamp lighting state, the first headlamp upward from the second headlamp is turned off, the second headlamp is turned on, and the oncoming vehicle is illuminated by the first headlamp. The front can be illuminated while avoiding the above.

Therefore, according to the fifth aspect of the present invention , by switching to the both-lights state at the time of work, it is easy to work by brightly illuminating the ground with the first and second headlamps. By switching to, it is possible to travel in a state where consideration is given to avoid irradiating the oncoming vehicle strongly by avoiding irradiation of the oncoming vehicle by the first headlamp.
