Japanese Utility Model Publication No. 63-23143 (page 2-5, Fig. 1-3)

  An object of the present invention is to provide a harvesting machine that is easy to perform night work and traveling while being able to obtain an advantageous state both in terms of structure and operation.

  In the first aspect of the present invention, a headlamp device for connecting the pre-harvest processing unit to the front part of the self-propelled aircraft and irradiating the front and lateral sides of the pre-harvest processing unit is provided in the pre-harvest processing unit. It is fixed.

  In the second aspect of the present invention, the right headlight device for connecting the pre-harvest processing unit to the front part of the self-propelled aircraft and irradiating the front and right lateral outer sides of the pre-harvest processing unit is provided before harvesting. Fixed to the right lateral outside of the processing section.

  In the third invention, the pre-harvest processing unit is connected to the front part of the self-propelled aircraft, and the left headlight device that irradiates the front and left lateral outer sides of the pre-harvest processing unit is pre-harvest. Fixed to the left lateral outside of the processing section.

  In the fourth invention, the pre-harvest processing unit is connected to the front part of the self-propelled aircraft, and the right headlight device that irradiates the front side and the right lateral outer side of the pre-harvest processing unit is pre-harvest. A left headlight device that is fixed to the right lateral outer side of the processing unit and irradiates the front and left lateral outer sides of the pre-harvest processing unit is fixed to the left lateral outer side of the pre-harvest processing unit.

  According to the fifth aspect of the present invention, in the configuration of any one of the first to fourth aspects of the present invention, the pre-harvest processing unit can be swung up and down freely between the lowering working state and the rising non-working state. When the pre-harvest processing unit is in the descending work state, the headlamp device irradiates the fixed weeding tool of the pre-harvest processing unit and the ground in front of the fixed weeding tool, and the pre-harvest processing unit When the headlamp device is in the non-working state, the headlamp device is irradiated in such a way that the headlight device irradiates the ground farther away from the self-propelled aircraft than when the pre-harvest processing unit is in the lowering work state. Is set.

  That is, when the pre-harvest processing unit is lowered to the descending work state, the headlamp device irradiates the fixed weed tool and the ground in front of it in order to set the irradiation direction of the headlamp device. When the headlight device is raised to the non-working state, the headlamp device irradiates the ground farther forward than the case where the pre-harvest processing unit is in the lowering work state due to the irradiation direction setting of the headlight device. A structure that only fixes the lighting device to the pre-harvest processing unit. Even if it is mounted with a simple mounting structure, and the pre-harvest processing unit is in a lowered working state or in a non-lifting non-working state, the desired fixing During work, the fixed weeding tool and the ground in front of it are illuminated while eliminating the need for adjustment mechanisms and adjustment work to adjust the irradiation direction of the headlamp device so that the weeding tool and the ground are illuminated. Make it easy to see the fixed weeds and their surroundings Rukoto can, at the time of movement can be on the front of the ground clarity travel destination illuminated than when working.

  Therefore, according to the fifth aspect of the present invention, it is easy to see the fixed weeding implement and its surroundings easily and easily to adjust the fixed weeding implement to the desired position and operating state even at night. In addition, it is possible to work while being adjusted with high accuracy, and even if the pre-harvest processing unit is raised to a non-working state, it is possible to move and travel more easily on the ground in front than when working. Nevertheless, the mounting structure of the headlamp device is simplified, the structure that eliminates the irradiation direction adjustment mechanism of the headlamp device can be simplified and obtained at low cost, and the adjustment operation of the irradiation direction can be performed. Even if it is not performed, it is only necessary to raise and lower the pre-harvest processing unit, and an advantageous operation can be obtained.

  In the sixth aspect of the invention, in the configuration of the fifth aspect of the invention, the headlamp device is configured to include a first headlamp and a second headlamp whose irradiation direction is downward from the first headlamp. ing.

  In other words, the illumination range necessary for work or movement is illuminated by the headlamp device composed of the first headlamp and the second headlamp having different irradiation directions, and the head is composed of either one of the headlamps. Compared to the illumination by the lighting device, the entire illumination range is illuminated brightly.

  Therefore, according to the sixth aspect of the present invention, the fixed weeding tool and the ground are illuminated brightly, and it is easier to see the weeding tool, the vicinity thereof, and the situation of the travel destination, and work and movement can be performed more easily.

  In the seventh aspect of the invention, in the configuration of the sixth aspect of the invention, the first headlamp is disposed above the body of the pre-harvest processing unit with respect to the second headlamp.

  That is, since the first headlamp is positioned above 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. Both headlamps can be installed while keeping the space in the lateral direction of the aircraft necessary for installing the lamps small.

  When the second headlamp with the downward illumination direction is placed on the upper side of the fuselage from the first headlamp, the second headlamp is mounted so that the fixed weed tool can be illuminated by the second headlamp. It is necessary to project 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 with the upward illumination direction is positioned above the fuselage from the second headlamp, the second headlamp projects to the front of the fuselage from the first headlamp. Without fixing, it is possible to irradiate the fixed weed tool and the front thereof while making the front surface of the headlamp device a flat surface or a state close thereto in a side view of the body.

  Therefore, according to the seventh aspect of the invention, the fixed weed tool and the front thereof are brightly illuminated by the first and second headlamps, but the headlamp device is installed with a small space in the lateral direction of the fuselage. It can be arranged in a compact space, and can be obtained in a simple state in which the front side of the headlamp device is a flat surface or a state close to it in a side view of the fuselage.

  In the eighth aspect of the present invention, in the configuration of the sixth or seventh aspect of the present invention, both the lighting state in which the first headlight and the second headlight are turned on, and the first headlight is turned off and the second front light is turned off. It is configured to be switchable to a single lamp lighting state in which an illumination lamp 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 eighth aspect of the invention, by switching between the two lamps at the time of work, the fixed weeding tool and the ground are brightly illuminated by the first and second headlamps while moving easily. Sometimes, by switching to the one-lamp lighting state, 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.
