従来のような、サイドカバーに大きな透光カバー部が備えられ、その内部に光源部及びリフレクタ部が配置されるような構成であると、この透光カバー部の面積が広ければ広いほど植立穀稈の穂先が接触しやすかったり、稈屑や土埃が付着しやすかったりする。これに対して、上述の構成によると、ライトユニット毎に透光カバー部が備えられた構成であるため、透光カバー部の面積を狭くすることができるので、植立穀稈の穂先が接触したり、稈屑や土埃が付着する虞が少ない。 In the conventional configuration where the side cover is provided with a large translucent cover and the light source and reflector are arranged inside, the wider the area of the translucent cover, the more planted. The tips of the grain culms are easy to come into contact with, and culms and dust are easy to adhere to. On the other hand, according to the above configuration, since each light unit is provided with a translucent cover portion, the area of the translucent cover portion can be narrowed, so that the tips of the planted culms come into contact with each other. There is little risk of culm or dirt adhering to it.

本発明においては、前記光源部は、LEDモジュールであると好適である。 In the present invention, it is preferable that the light source unit is an LED module.

上述の構成によると、ハロゲンランプのような白熱電球に比べて、発電効率が高いため低発熱であり長寿命である。 According to the above configuration, compared to an incandescent lamp such as a halogen lamp, the power generation efficiency is high, so that the heat generation is low and the life is long.

本発明においては、前記第一前照灯及び前記第二前照灯が点灯する両灯火状態と、前記第一前照灯又は前記第二前照灯のいずれか一方のみが点灯する片灯火状態とが、切り替え自在に構成されていると好適である。 In the present invention, the two-light state in which the first headlight and the second headlight are lit, and the single-light state in which only one of the first headlight or the second headlight is lit. It is preferable that and is configured to be switchable.

上述の構成によると、例えば、刈り取り作業時には、第一前照灯及び第二前照灯によって広範囲に亘って照明することで作業性を向上させ、路上走行時には、第一前照灯又は第二前照灯のいずれか一方のみによって照明することで省エネを図ることができるといった運用が可能となる。 According to the above configuration, for example, during mowing work, workability is improved by illuminating a wide area with the first headlight and the second headlight, and when traveling on the road, the first headlight or the second headlight or the second. It is possible to save energy by lighting with only one of the headlights.

It is configured to be larger than the outer diameter of the 31 and the second headlight 32 by the amount that the first headlight 31 and the second headlight 32 can pass through.

〔前照灯〕
第一前照灯用開口部25に第一前照灯31が配置され、第二前照灯用開口部26に第二前照灯32が配置されている。したがって、第一前照灯31及び第二前照灯32は、第一前照灯31が第二前照灯32の上方に位置する状態で上下に離間した位置に並べて個別に配置されている。
[Headlight]
The first headlight 31 is arranged in the opening 25 for the first headlight, and the second headlight 32 is arranged in the opening 26 for the second headlight. Therefore, the first headlight 31 and the second headlight 32 are individually arranged side by side at vertically separated positions with the first headlight 31 located above the second headlight 32. ..

第一前照灯31及び第二前照灯32はそれぞれ、光を発光する光源部(図示せず)と、該光源部から照射された光を反射するリフレクタ部(図示せず)と、前記光源及び前記リフレクタ部を収容する第一ハウジング部31A及び第二ハウジング部32A、該リフレクタ部を第一透光カバー部31B及び第二透光カバー部32Bとを一体的に有するライトユニットから構成されている。第一透光カバー部31B及び第二透光カバー部32Bは透光性を有する樹脂、例えばポリカーボネートを所定形状に加工することによって形成されている。 The first headlight 31 and the second headlight 32 have a light source unit (not shown) that emits light, a reflector unit (not shown) that reflects the light emitted from the light source unit, and the above. It is composed of a first housing portion 31A and a second housing portion 32A for accommodating a light source and the reflector portion, and a light unit having the reflector portion integrally with a first translucent cover portion 31B and a second translucent cover portion 32B. ing. The first translucent cover portion 31B and the second translucent cover portion 32B are formed by processing a translucent resin, for example, polycarbonate, into a predetermined shape.

上部カバー22には、カバー用開口部23の全面を覆うような透光カバー部が備えられないため、第一前照灯31及び第二前照灯32は、投光部、すなわち第一透光カバー部31B及び第二透光カバー部32Bが機体前方に露出する状態で配置される。 Since the upper cover 22 is not provided with a translucent cover portion that covers the entire surface of the cover opening 23, the first headlight 31 and the second headlight 32 are a light projecting portion, that is, the first translucent portion. The light cover portion 31B and the second translucent cover portion 32B are arranged so as to be exposed in front of the machine body.

なお、第一前照灯31及び第二前照灯32に備えられた光源部は、LEDモジュールであり、距離25mにおいて1lx照度(すなわち輝度625cd)程度、かつ、光軸31C,32Cから左右に30~35度程度、例えば32度、かつ、上下に20~25度程度、例えば22度の照射角度を有するものが好ましく用いられる。 The light source unit provided in the first headlight 31 and the second headlight 32 is an LED module, which has an illuminance of about 1 lx (that is, a brightness of 625 cd) at a distance of 25 m and is left and right from the optical axes 31C and 32C. Those having an irradiation angle of about 30 to 35 degrees, for example 32 degrees, and an irradiation angle of about 20 to 25 degrees up and down, for example 22 degrees, are preferably used.

第一前照灯31及び第二前照灯32は、上述の範囲内において輝度625cdを満足するように照明するのであるが、上記範囲のみを照明するわけではなく、上記範囲の周囲も上記範囲内に劣るが照明する。図11及び図12においては、第一前照灯31の光軸31C及び第二前照灯32の光軸32Cを実線で示し、輝度625cdを満足する範囲を二点鎖線で示し、その範囲の周囲であっても第一前照灯31及び第二前照灯32によって照明される範囲を薄い網掛けで示している。 The first headlight 31 and the second headlight 32 illuminate so as to satisfy the luminance 625 cd within the above range, but they do not illuminate only the above range, and the periphery of the above range is also the above range. It is inferior to the inside, but it illuminates. In FIGS. 11 and 12, the optical axis 31C of the first headlight 31 and the optical axis 32C of the second headlight 32 are shown by a solid line, and the range satisfying the luminance 625cd is shown by a two-dot chain line. Even in the surrounding area, the range illuminated by the first headlight 31 and the second headlight 32 is shown by a thin shade.

図8に示すように、第一前照灯31を構成するライトユニットが有する第一透光カバー部31B及び第二前照灯32を構成するライトユニットが有する第二透光カバー部32Bは、それぞれが、前照灯カバー24の第一前照灯用開口部25の第一開口縁25A及び第二前照灯用開口部26の第二開口縁26Aよりも、光の照射方向の前方に突出するように配置されている。したがって、前照灯カバー24が、第一前照灯31及び第二前照灯32からの投光を遮らないようになっている。 As shown in FIG. 8, the first translucent cover portion 31B included in the light unit constituting the first headlight 31 and the second translucent cover portion 32B included in the light unit constituting the second headlight 32 are Each is in front of the first opening edge 25A of the first headlight opening 25 of the headlight cover 24 and the second opening edge 26A of the second headlight opening 26 in the light irradiation direction. It is arranged so as to protrude. Therefore, the headlight cover 24 does not block the light projected from the first headlight 31 and the second headlight 32.

第一前照灯31及び第二前照灯32は、ライトユニットから構成されているため、上部カバー22にライトユニット毎に個別に着脱可能に構成することができることからメンテナンス性がよい。また、第一前照灯31及び第二前照灯32にそれぞれ第一透光カバー部31B及び第二透光カバー部32Bが備えられた構成であるため、第一透光カバー部31B及び第二透光カバー部32Bの面積を狭くすることができるので、植立穀稈の穂先が接触したり、稈屑や土埃が付着する虞が少ない。 Since the first headlight 31 and the second headlight 32 are composed of light units, they can be individually attached to and detached from the upper cover 22 for each light unit, so that maintainability is good. Further, since the first headlight 31 and the second headlight 32 are provided with the first translucent cover portion 31B and the second translucent cover portion 32B, respectively, the first translucent cover portion 31B and the second translucent cover portion 31B are provided. (2) Since the area of the translucent cover portion 32B can be narrowed, there is little possibility that the tips of the planted grain stalks come into contact with each other and that shavings and dust adhere to them.

なお、第一前照灯31及び第二前照灯32は、第一前照灯31及び第二前照灯32が点灯する両灯火状態と、第一前照灯31又は第二前照灯32のいずれか一方のみが点灯する片灯火状態とが、切り替え自在に構成されている。 The first headlight 31 and the second headlight 32 are in both lighting states in which the first headlight 31 and the second headlight 32 are lit, and the first headlight 31 or the second headlight 32. The one-sided lighting state in which only one of the 32 lights is turned on is freely switched.

例えば、刈り取り作業時には、第一前照灯31及び第二前照灯32によって広範囲に亘って照明することで作業性を向上させ、路上走行時には、第一前照灯31又は第二前照灯32のいずれか一方のみによって照明することで省エネを図ることができるといった運用が可能となっている。なお、第一前照灯31及び第二前照灯32は両方とも消灯させることもできるように構成されている。 For example, during mowing work, the first headlight 31 and the second headlight 32 are used to illuminate a wide area to improve workability, and when traveling on the road, the first headlight 31 or the second headlight 32 is used. It is possible to save energy by lighting with only one of the 32. Both the first headlight 31 and the second headlight 32 can be turned off.

〔照射方向及び照射範囲〕
図11及び図12に示すように、第一前照灯31の光軸31Cは、第二前照灯32の光軸32Cよりも、機体幅方向の内側を向くように構成され、第二前照灯32の光軸32Cは、第一前照灯31の光軸31Cよりも、機体幅方向の外側を向くように構成されている。また、作業状態において、第二前照灯32は、第二前照灯32の光軸32Cが第一前照灯31の光軸31Cよりも下側を向くように配置されている。第二前照灯32よりも高い位置にある第一前照灯31によって機体前方の遠方を照明することができ、第一前照灯31よりも圃場に近い位置にある第二前照灯32によって、しっかりと機体に近い部分を明るく照明できる。
[Irradiation direction and range]
As shown in FIGS. 11 and 12, the optical axis 31C of the first headlight 31 is configured to face inward in the width direction of the machine body with respect to the optical axis 32C of the second headlight 32, and the second front. The optical axis 32C of the illuminating lamp 32 is configured to face the outside in the width direction of the machine body with respect to the optical axis 31C of the first headlight 31. Further, in the working state, the second headlight 32 is arranged so that the optical axis 32C of the second headlight 32 faces downward from the optical axis 31C of the first headlight 31. The first headlight 31 located higher than the second headlight 32 can illuminate a distant place in front of the aircraft, and the second headlight 32 located closer to the field than the first headlight 31. This makes it possible to brightly illuminate the part close to the aircraft.

具体的には、第一前照灯31の光軸31Cは、機体前方に対して5度の傾斜角度で機体幅方向の内側を向き、機体前方に対して3度の傾斜角度で機体1の下側を向いた姿勢となるように備えられている。 Specifically, the optical axis 31C of the first headlight 31 faces inward in the width direction of the aircraft at an inclination angle of 5 degrees with respect to the front of the aircraft, and the optical axis 31C of the aircraft 1 has an inclination angle of 3 degrees with respect to the front of the aircraft. It is provided so that it faces downward.

第二前照灯32の光軸32Cは、機体前方に対して16度の傾斜角度で機体幅方向の外側を向き、機体前方に対して19.5度の傾斜角度で機体1の下側を向いた姿勢となるように備えられている。 The optical axis 32C of the second headlight 32 faces the outside in the width direction of the aircraft at an inclination angle of 16 degrees with respect to the front of the aircraft, and faces the underside of the aircraft 1 at an inclination angle of 19.5 degrees with respect to the front of the aircraft. It is prepared to be in a facing position.

第一前照灯31は、機体前方よりも機体幅方向の内側を主に照明し、第二前照灯32は、機体前方よりも機体幅方向の外側を主に照明することができるので、第一前照灯31と第二前照灯32との照明範囲の重なりが少なく、広範囲に亘って照明することができる。 Since the first headlight 31 can mainly illuminate the inside in the width direction of the aircraft rather than the front of the aircraft, and the second headlight 32 can mainly illuminate the outside in the width direction of the aircraft than the front of the aircraft. There is little overlap in the lighting range between the first headlight 31 and the second headlight 32, and it is possible to illuminate a wide range.

図6に示すように、第一前照灯31は、第一前照灯31の投光部、すなわち第一透光カバー部31Bが、第二前照灯32の投光部、すなわち第二透光カバー部32Bよりも機体幅方向の内側に位置するように配置されている。作物が長稈であっても、第二前照灯32よりも高い位置に設けられ、植立穀稈の影になりにくい第一前照灯31によって内側を照明し、かつ、第一前照灯31よりも低い位置に設けられ、正面を照明すると、長稈の影になりかねない第二前照灯32によって外側を照明することで、第一前照灯31と第二前照灯32との高さが上下に異なることを上手く利用して、圃場をまんべんなく、かつ効率よく照明できる。 As shown in FIG. 6, in the first headlight 31, the light projecting unit of the first headlight 31, that is, the first translucent cover unit 31B is the light projecting unit of the second headlight 32, that is, the second. It is arranged so as to be located inside the translucent cover portion 32B in the width direction of the machine body. Even if the crop is a long headlight, the inside is illuminated by the first headlight 31 which is installed at a position higher than the second headlight 32 and is less likely to be a shadow of the planted grain headlight, and the first headlight. The first headlight 31 and the second headlight 32 are provided at a position lower than the light 31, and when the front is illuminated, the outside is illuminated by the second headlight 32, which may be a shadow of a long headlight 32. By making good use of the fact that the heights of the headlights are different up and down, the fields can be illuminated evenly and efficiently.

第一前照灯31は、第二前照灯32よりも上方に位置するため、その投光が植立穀稈の穂先によって遮られにくい。この第一前照灯31の光軸31Cを、第二前照灯32の光軸32Cよりも、機体幅方向の内側を向けることによって、第一前照灯31の照明範囲31Dは、第二前照灯32の照射範囲32Dよりも機体幅方向の内側を向く。第一前照灯31によって、刈り取り対象となる、刈取部10の直前の植立穀稈の生育状態や圃場の状態が視認しやすくなった。 Since the first headlight 31 is located above the second headlight 32, its floodlight is less likely to be blocked by the tips of the planted grain culms. By directing the optical axis 31C of the first headlight 31 toward the inside in the width direction of the machine body with respect to the optical axis 32C of the second headlight 32, the illumination range 31D of the first headlight 31 is second. It faces inward in the width direction of the aircraft from the irradiation range 32D of the headlight 32. The first headlight 31 makes it easier to visually recognize the growing state of the planted culm immediately before the cutting section 10 and the state of the field, which are the targets of cutting.

左右の第一前照灯31は、両照明範囲31Dによって、機体前方を刈取部10の刈幅の全幅に亘るように配置されている。左右の第一前照灯31によって、機体前方が刈取部10の刈幅の全幅に亘って照明されるため、刈幅内の植立穀稈の生育状態や圃場の状態を視認しやすい。 The left and right first headlights 31 are arranged so as to cover the entire width of the cutting portion 10 in front of the machine body by both lighting ranges 31D. Since the front of the machine body is illuminated by the left and right first headlights 31 over the entire width of the cutting portion 10, it is easy to visually recognize the growing state of the planted culm within the cutting width and the state of the field.

少なくとも第一前照灯31又は第二前照灯32のいずれかによって、分草具12の一部、好ましくは先端部が照明されるため、刈り取り対象である植立穀稈と既刈地との境界や、刈り取り対象である植立穀稈と未刈地の植立穀稈との境界を視認しやすい。 At least one of the first headlight 31 or the second headlight 32 illuminates a part of the weeding tool 12, preferably the tip portion, so that the planted culm and the cut land to be cut are used. It is easy to see the boundary between the planted culm and the planted culm of the uncut land.

〔前照灯カバー〕
図6から図8に示すように、前照灯カバー24は、第一前照灯用開口部25の前方下方に、第一前照灯31の光軸31Cの方向よりも前下がりの第一傾斜面27Aが設けられている。同様に、前照灯カバー24は、第二前照灯用開口部26の前方下方に、第二前照灯32の光軸32Cの方向よりも前下がりの第二傾斜面28Aが設けられている。第一前照灯31及び第二前照灯32の前方において、前下がりの傾斜面を設けたことにより、前照灯カバー24に稈屑や土埃が積もりにくい。第二傾斜面28Aは、第一傾斜面27Aよりも前下がりであるため、第二前照灯32の光軸32Cを、第一前照灯31の光軸31Cよりも下側に向けることができて、第一前照灯31よりも圃場に近い位置にある第二前照灯32によって、しっかりと機体に近い部分を明るく照明できる。
[Headlight cover]
As shown in FIGS. 6 to 8, the headlight cover 24 is a first headlamp that descends forward from the direction of the optical axis 31C of the first headlight 31 at the lower front side of the opening 25 for the first headlight. An inclined surface 27A is provided. Similarly, the headlight cover 24 is provided with a second inclined surface 28A that is lower than the direction of the optical axis 32C of the second headlight 32 at the lower front side of the opening 26 for the second headlight. There is. By providing a front-down inclined surface in front of the first headlight 31 and the second headlight 32, it is difficult for culms and dust to accumulate on the headlight cover 24. Since the second inclined surface 28A is lower than the first inclined surface 27A, the optical axis 32C of the second headlight 32 can be directed downward from the optical axis 31C of the first headlight 31. The second headlight 32, which is closer to the field than the first headlight 31, can illuminate the part close to the aircraft firmly and brightly.

前照灯カバー24は、前照灯カバー24における第一前照灯用開口部25の前方上方に、第一前照灯31の投光部、すなわち第一透光カバー部31Bよりも機体前方へ突出する第一庇状部27Bが設けられ、前照灯カバー24における第二前照灯用開口部26の前方上方に、第二前照灯32の投光部、すなわち第二透光カバー部32Bよりも機体前方へ突出する第二庇状部28Bが設けられている。第一庇状部27B及び第二庇状部28Bの存在によって第一前照灯31及び第二前照灯32は前方上方が覆われるため、雨水やサイドカバーについた水分が第一透光カバー部31Bや第二透光カバー部32Bにかかりにくくいため、濡れた第一透光カバー部31Bや第二透光カバー部32Bに穀稈が触れて稈屑や土埃が付着する事態を防止できる。 The headlight cover 24 is located above the front of the first headlight opening 25 in the headlight cover 24, and is in front of the light projecting portion of the first headlight 31, that is, the first translucent cover portion 31B. A first headlight-shaped portion 27B projecting to the front is provided, and a light projecting portion of the second headlight 32, that is, a second translucent cover is provided above the front of the opening 26 for the second headlight in the headlight cover 24. A second hull-shaped portion 28B is provided so as to project forward from the portion 32B. The presence of the first eaves-shaped portion 27B and the second eaves-shaped portion 28B covers the front upper part of the first headlight 31 and the second headlight 32, so that rainwater and moisture on the side cover are the first translucent cover. Since it is difficult to get on the portion 31B and the second translucent cover portion 32B, it is possible to prevent the situation where the eaves come into contact with the wet first translucent cover portion 31B and the second translucent cover portion 32B and the eaves and dust adhere to the portion 31B and the second translucent cover portion 32B.

第一庇状部27B及び第二庇状部28Bは、第一庇状部27Bや第二庇状部28Bは、第一前照灯31や第二前照灯32の前方上方を覆って保護しながらも、第一前照灯31や第二前照灯32からの投光を遮ることがないように、機体幅方向の内側部分から外側部分にかけて機体後方かつ上方に向けて延びる形状に構成されている。穀稈は、第一庇状部27B及び第二庇状部28Bに沿って機体後方の上方へとスムーズに案内されるため、脱粒の虞が低減される。 The first eaves-shaped portion 27B and the second eaves-shaped portion 28B are protected by the first eaves-shaped portion 27B and the second eaves-shaped portion 28B covering the front upper part of the first headlight 31 and the second headlight 32. However, it is configured to extend backward and upward from the inner part to the outer part in the width direction of the aircraft so as not to block the light emitted from the first headlight 31 and the second headlight 32. Has been done. Since the grain culm is smoothly guided upward to the rear of the machine along the first eaves-shaped portion 27B and the second eaves-shaped portion 28B, the risk of shedding is reduced.

さらに、前照灯カバー24は、前照灯カバー24における第一前照灯用開口部25の機体幅方向の内側に、上部カバー22の表面に沿って上下に延びて第一庇状部27Bの機体幅方の内側部分に連なる第一縦壁部27Cが設けられ、前照灯カバー24における第二前照灯用開口部26の機体幅方向の内側に、上部カバー22の表面に沿って上下に延びて第二庇状部28Bの機体幅方の内側部分に連なる第二縦壁部28Cが設けられている。 Further, the headlight cover 24 extends vertically along the surface of the upper cover 22 inside the first headlight opening 25 in the headlight cover 24 in the machine width direction, and the first headlight-shaped portion 27B. A first vertical wall portion 27C connected to the inner portion of the body width is provided, and the second headlight opening 26 in the headlight cover 24 is provided inside in the body width direction along the surface of the upper cover 22. A second vertical wall portion 28C that extends vertically and is connected to the inner portion of the second hull-shaped portion 28B in the width direction of the machine body is provided.

第一前照灯31は、第一傾斜面27Aと第一庇状部27Bと第一縦壁部27Cとに連続的に囲まれ、第二前照灯32は、第二傾斜面28Aと第二庇状部28Bと第二縦壁部28Cとに連続的に囲まれるため、植立穀稈の穂先が接触する虞が低減されている。植立穀稈の穂先は、第一庇状部27B及び第一縦壁部27C、第二庇状部28B及び第二縦壁部28Cに沿って機体後方の上方へとスムーズに案内されるため、脱粒の虞が低減されている。 The first headlight 31 is continuously surrounded by the first inclined surface 27A, the first eaves-shaped portion 27B, and the first vertical wall portion 27C, and the second headlight 32 has the second inclined surface 28A and the second. Since it is continuously surrounded by the two eaves-shaped portion 28B and the second vertical wall portion 28C, the possibility that the tips of the planted culms come into contact with each other is reduced. The tip of the planted culm is smoothly guided upward to the rear of the machine along the first eaves-shaped portion 27B and the first vertical wall portion 27C, the second eaves-shaped portion 28B and the second vertical wall portion 28C. , The risk of shedding is reduced.

〔前照灯ブラケット〕
図8から図10に示すように、前照灯カバー24や、第一前照灯31及び第二前照灯32は、前照灯ブラケット40を介して刈取フレーム11のブラケットステー17に取り付けられる。
[Headlight bracket]
As shown in FIGS. 8 to 10, the headlight cover 24, the first headlight 31 and the second headlight 32 are attached to the bracket stay 17 of the cutting frame 11 via the headlight bracket 40. ..

前照灯ブラケット40は、第一前照灯31や第二前照灯32を個別に着脱可能なライトステー41,42や、前照灯カバー24が着脱可能なカバーステー43を有する部材である。前照灯ブラケット40、ライトステー41,42及びカバーステー43は、ステンレス鋼のような耐食性のある金属から構成された形材を所定形状に加工することによって形成されている。 The headlight bracket 40 is a member having a light stays 41 and 42 to which the first headlight 31 and the second headlight 32 can be individually attached and detached, and a cover stay 43 to which the headlight cover 24 can be attached and detached. .. The headlight bracket 40, the light stays 41, 42, and the cover stay 43 are formed by processing a profile made of a corrosion-resistant metal such as stainless steel into a predetermined shape.

前照灯カバー24や、第一前照灯31及び第二前照灯32が取り付けられた状態の前照灯ブラケット40を、刈取フレーム11に取り付ける構成であるため、第一前照灯31及び第二前照灯32を配線したまま、上部カバー22のみを着脱することができるように構成されている。 Since the headlight cover 24 and the headlight bracket 40 in which the first headlight 31 and the second headlight 32 are attached are attached to the cutting frame 11, the first headlight 31 and the second headlight 32 and the headlight bracket 40 are attached. It is configured so that only the upper cover 22 can be attached / detached while the second headlight 32 is wired.

なお、前照灯カバー24は、カバー用開口部23の周縁部の裏面に係止可能なフランジ部24Aを有する。前照灯カバー24に被せるように上部カバー22を取り付けると、フランジ部24Aがカバー用開口部23の周縁部の裏面に係止され、前照灯カバー24は、上部カバー22のカバー用開口部23に対して自動的に位置決めされる。前照灯カバー24の位置決めのために螺子を用いる必要がない。 The headlight cover 24 has a flange portion 24A that can be locked on the back surface of the peripheral edge portion of the cover opening 23. When the upper cover 22 is attached so as to cover the headlight cover 24, the flange portion 24A is locked to the back surface of the peripheral edge portion of the cover opening 23, and the headlight cover 24 is the cover opening of the upper cover 22. It is automatically positioned with respect to 23. It is not necessary to use screws for positioning the headlight cover 24.

なお、カバー用開口部23と前照灯カバー24との間に大きな隙間があると、この隙間から上部カバー22内に穀稈が入る虞があるが、フランジ部24Aを設けたことによりこれを防止することができる。なお、フランジ部24Aは、前照灯カバー24の全周に亘って備えられていてもよいし、一部に備えられていてもよい。 If there is a large gap between the cover opening 23 and the headlight cover 24, there is a risk that grain culms may enter the upper cover 22 through this gap. Can be prevented. The flange portion 24A may be provided over the entire circumference of the headlight cover 24, or may be provided in a part thereof.

上部カバー22は、第一前照灯31及び第二前照灯32が取り付けられた状態のままで着脱できるため、上部カバー22を刈取フレーム11から取り外すと、ライトステー41,42がむき出しになり、第一前照灯31や第二前照灯32を交換することができるため、メンテナンス性が良い。 Since the upper cover 22 can be attached and detached with the first headlight 31 and the second headlight 32 attached, when the upper cover 22 is removed from the cutting frame 11, the light stays 41 and 42 are exposed. Since the first headlight 31 and the second headlight 32 can be replaced, maintainability is good.

第一前照灯用開口部25の開口寸法及び第二前照灯用開口部26は、第一前照灯31や第二前照灯32の外径寸法よりも大きいように構成されてあり、前照灯カバー24を前照灯ブラケット40に取り付けたままの状態であっても、第一前照灯31や第二前照灯32は個別に着脱することができるように構成されている。第一前照灯31や第二前照灯32の交換作業が容易である。なお、交換作業は、上部カバー22が取り外された状態で行われる。 The opening size of the first headlight opening 25 and the opening 26 for the second headlight are configured to be larger than the outer diameter size of the first headlight 31 and the second headlight 32. The first headlight 31 and the second headlight 32 can be individually attached and detached even when the headlight cover 24 is still attached to the headlight bracket 40. .. The replacement work of the first headlight 31 and the second headlight 32 is easy. The replacement work is performed with the upper cover 22 removed.

第一前照灯31及び第二前照灯32を刈取部10に取り付ける際には、前照灯ブラケット40のライトステー41,42に第一前照灯31や第二前照灯32を取り付け、その後、カバーステー43に前照灯カバー24を取り付ける。この一体化された前照灯ブラケット40を、刈取フレーム11に設けられたブラケットステー17に取り付け、最後に上部カバー22を取り付ける。分解は逆の手順で行われる。 When attaching the first headlight 31 and the second headlight 32 to the cutting section 10, the first headlight 31 and the second headlight 32 are attached to the light stays 41 and 42 of the headlight bracket 40. After that, the headlight cover 24 is attached to the cover stay 43. The integrated headlight bracket 40 is attached to the bracket stay 17 provided on the cutting frame 11, and finally the upper cover 22 is attached. The disassembly is performed in the reverse procedure.

なお、前照灯カバー24に、第一前照灯31及び前記第二前照灯32に並んで、車幅灯や方向指示器が配置されていてもよい。車幅灯や方向指示器も前照灯ブラケット40に支持される。 In addition, a vehicle side light and a direction indicator may be arranged on the headlight cover 24 alongside the first headlight 31 and the second headlight 32.
