And each of these members is comprised so that it may rotate by operation of the operation tool of a driving | operation operation part, and excavation work, loading work, etc. can be performed with the excavation work apparatus 4. FIG.

次に、ボンネット１１内の構成について説明する。   Next, the configuration inside the hood 11 will be described.

図２に示すように、ボンネット１１は旋回台７後部の円弧状の外周に沿って着脱可能に設けられて、前記エンジン８に加えて当該旋回台７上の油圧ポンプ３１やラジエータ３２などを被装するように構成されている。このボンネット１１内においては、エンジン８が左右略中央に配置されて、該エンジン８の左側方に油圧ポンプ３１が配置され、該エンジン８の右側方にラジエータ３２が配置されている。   As shown in FIG. 2, the bonnet 11 is detachably provided along the arc-shaped outer periphery of the rear part of the swivel base 7 and covers the hydraulic pump 31 and the radiator 32 on the swivel base 7 in addition to the engine 8. It is configured to wear. In the bonnet 11, the engine 8 is disposed substantially at the center on the left and right, the hydraulic pump 31 is disposed on the left side of the engine 8, and the radiator 32 is disposed on the right side of the engine 8.

エンジン８の左側方では、油圧ポンプ３１がエンジン８の出力軸に連結されて、該エンジン８により駆動可能とされている。そしてこの油圧ポンプ３１によって、作動油タンクから前記掘削作業装置４のシリンダ２４・２５・２６などの油圧機器にコントロールバルブを介して作動油を供給して、該油圧機器を作動させることができるようになっている。   On the left side of the engine 8, a hydraulic pump 31 is connected to the output shaft of the engine 8 and can be driven by the engine 8. The hydraulic pump 31 supplies hydraulic oil from the hydraulic oil tank to the hydraulic equipment such as the cylinders 24, 25, and 26 of the excavation work device 4 via the control valve so that the hydraulic equipment can be operated. It has become.

エンジン８の右側方では、当該エンジン８とラジエータ３２との間に冷却ファン３３が設けられている。冷却ファン３３はエンジン８の出力軸に伝動機構を介して連動連結されて、該エンジン８により駆動可能とされている。そしてこの冷却ファン３３によって、当該冷却ファン３３に対向配置されたラジエータ３２に冷却風を供給して、該ラジエータ３２を冷却することができるようになっている。   On the right side of the engine 8, a cooling fan 33 is provided between the engine 8 and the radiator 32. The cooling fan 33 is linked to the output shaft of the engine 8 through a transmission mechanism and can be driven by the engine 8. The cooling fan 33 can cool the radiator 32 by supplying cooling air to the radiator 32 disposed opposite to the cooling fan 33.

ここで、ラジエータ３２と冷却ファン３３との間には、シュラウド３４が設けられている。シュラウド３４は冷却ファン３３の一部を覆うように配置される一方、ラジエータ３２の表面積と略同等の開口面積を有するように形成されて、該ラジエータ３２に密接されている。こうして、冷却ファン３３の回転により起きる冷却風がシュラウド３４内を通って、該ラジエータ３２に導かれるようになっている。   Here, a shroud 34 is provided between the radiator 32 and the cooling fan 33. The shroud 34 is disposed so as to cover a part of the cooling fan 33, and is formed so as to have an opening area substantially equal to the surface area of the radiator 32 and is in close contact with the radiator 32. Thus, the cooling air generated by the rotation of the cooling fan 33 passes through the shroud 34 and is guided to the radiator 32.

ラジエータ３２のエンジン８と反対側（右側）で、当該ラジエータ３２とボンネット１１の側壁１１ａとの間には、ダクト４０が設けられている。ダクト４０は、図３乃至図６に示すように、上下に配置される天板４１および底板４２と、前後に配置される側板４３・４４とで筒状に構成され、一側の開口部をラジエータ３２に向かって開口し、他側の開口部をボンネット１１の側壁１１ａに向かって開口するように配置されている。   A duct 40 is provided between the radiator 32 and the side wall 11 a of the bonnet 11 on the side (right side) opposite to the engine 8 of the radiator 32. As shown in FIGS. 3 to 6, the duct 40 is formed in a cylindrical shape with a top plate 41 and a bottom plate 42 arranged on the top and bottom, and side plates 43 and 44 arranged on the front and back, and has an opening on one side. It opens toward the radiator 32, and the opening on the other side is arranged to open toward the side wall 11 a of the bonnet 11.

ダクト４０はその外周縁部を平面視でボンネット１１の外周形状に合わせて湾曲し、前部が幅広となり、後部が幅狭となるように形成されている。そして、一側の開口部が前記シュラウド３４と同じくラジエータ３２の表面積と略同等の開口面積を有する形状とされて、ラジエータ３２に密接されるとともに、他側の開口部がボンネット側壁１１ａに縁部に備えてシール部材を介して密接されている。   The duct 40 is curved so that the outer peripheral edge portion thereof conforms to the outer peripheral shape of the bonnet 11 in a plan view, the front portion is wide, and the rear portion is narrow. Then, the opening on one side is shaped to have an opening area substantially the same as the surface area of the radiator 32 like the shroud 34 and is in close contact with the radiator 32, while the opening on the other side is an edge on the bonnet side wall 11a. In close contact with each other through a seal member.

ボンネット側壁１１ａの前記ダクト４０の開口部に面する部分には開口部１１ｂが設けられ、該開口部１１ｂを通じてダクト４０が外部と連通されている。こうして、冷却ファン３３から送られる冷却風がラジエータ３２を冷却した後、ダクト４０内を通って、ボンネット１１の開口部１１ｂから外部に排出されるようになっている。なお、開口部１１ｂには横桟が上下平行に横架されるとともに、網状部材が設けられている。   A portion of the bonnet side wall 11a facing the opening of the duct 40 is provided with an opening 11b, and the duct 40 communicates with the outside through the opening 11b. Thus, the cooling air sent from the cooling fan 33 cools the radiator 32, passes through the duct 40, and is discharged to the outside from the opening 11 b of the bonnet 11. The opening 11b is provided with a horizontal member and a mesh member.

このようなダクト４０において、図３に示すように、底板４２はラジエータ３２側縁部が低位置となり、ボンネット側壁１１ａの開口部１１ｂ側縁部が高位置となるように斜設され、該ボンネット側壁１１ａの開口部１１ｂに向かって斜め上向きに配置されている。この底板４２によって、ダクト４０内を通過する冷却風を斜め上向きに案内して、そのまま排風としてボンネット側壁１１ａの開口部１１ｂから外部へ排出することができるようになっている。   In such a duct 40, as shown in FIG. 3, the bottom plate 42 is obliquely installed so that the side edge of the radiator 32 is at a low position and the side edge of the opening 11b of the bonnet side wall 11a is at a high position. It arrange | positions diagonally upward toward the opening part 11b of the side wall 11a. By this bottom plate 42, the cooling air passing through the duct 40 is guided obliquely upward, and can be discharged directly from the opening 11b of the bonnet side wall 11a as exhaust air.

なお、前記ボンネット側壁１１ａに設ける開口部１１ｂの下部は旋回台７上に配置されるラジエータ３２の下部よりも高い位置に設定される。そして、これらの間にダクト４０の底板４２がその高さを合わせて斜めに配置されて、ラジエータ３２側からの排風を斜め上方に導き、開口部１１ｂから排出された排風が旋回作業車１の側部を通る歩行者などに側方から当たり難い構成とされる。   In addition, the lower part of the opening part 11b provided in the said bonnet side wall 11a is set to a position higher than the lower part of the radiator 32 arrange | positioned on the swivel base 7. FIG. Between these, the bottom plate 42 of the duct 40 is disposed obliquely so as to match the height thereof, and the exhausted air from the radiator 32 side is guided obliquely upward, and the exhausted air discharged from the opening 11b is turned into the turning work vehicle. It is set as the structure which is hard to hit from the side to the pedestrian etc. which pass 1 side part.

さらに、ダクト４０の底板４２がラジエータ３２を支持するラジエータ支持フレーム３６の下部に上下方向に回動可能に支持されている。たとえば、図４、図６に示すように、底板４２のラジエータ３２側縁部に前後方向に所定間隔をおいて一対の蝶番４６が配置され、その一片が底板４２に固定され、他片がラジエータ支持フレーム３６に固定されている。こうして、底板４２が蝶番４６の前後方向の回動軸４６ａを中心として上下方向に回動可能に支持されている。   Furthermore, the bottom plate 42 of the duct 40 is supported by the lower part of the radiator support frame 36 that supports the radiator 32 so as to be rotatable in the vertical direction. For example, as shown in FIGS. 4 and 6, a pair of hinges 46 are arranged at predetermined intervals in the front-rear direction on the side edge of the radiator 32 of the bottom plate 42, one piece is fixed to the bottom plate 42, and the other piece is the radiator. It is fixed to the support frame 36. Thus, the bottom plate 42 is supported so as to be pivotable in the vertical direction about the pivot shaft 46 a in the front-rear direction of the hinge 46.

ダクト４０の前側板４３には、底板４２の上方（ラジエータ３２側）または下方（旋回台７側）へ回動を規制し、かつ、その規制位置で当該底板４２を上方または下方へ回動した状態に保持する上下の保持部材５１・５６が設けられている。これらの保持部材５１・５６による底板４２の規制位置は、下方へ回動した状態では、該底板４２がダクト４０の底部を構成し、つまり、前述のように斜設した状態に保持され、上方へ回動した状態では、底板４２が上下方向に延伸し、ダクト４０の底部（バッテリ６０の上方）が開放されるように設定されている。   The front plate 43 of the duct 40 restricts the rotation of the bottom plate 42 above (the radiator 32 side) or below (the swivel base 7 side) and rotates the bottom plate 42 upward or downward at the restriction position. Upper and lower holding members 51 and 56 for holding the state are provided. When the bottom plate 42 is regulated downward by the holding members 51 and 56, the bottom plate 42 constitutes the bottom portion of the duct 40 when it is rotated downward, that is, is held obliquely as described above. In the state rotated to the bottom, the bottom plate 42 is set to extend in the vertical direction, and the bottom portion of the duct 40 (above the battery 60) is opened.

前側板４３の下側の保持部材５１は、当該前側板４３のボンネット側壁１１ａ側底部からダクト４０内（後方）へ略水平に突出する保持片５２と、該保持片５２の底面に固設されたナット５３とで構成されている。この保持片５２は底板４２が下方へ回動した場合に、該底板４２に当接してこれを下方から支持し、該底板４２の下方への回動を規制する（ストッパーとなる）ようになっている。   The holding member 51 on the lower side of the front plate 43 is fixed to a holding piece 52 that protrudes substantially horizontally from the bottom of the front plate 43 on the bonnet side wall 11a side into the duct 40 (rear), and the bottom surface of the holding piece 52. And a nut 53. When the bottom plate 42 rotates downward, the holding piece 52 comes into contact with and supports the bottom plate 42 from below, and restricts the bottom plate 42 from rotating downward (becomes a stopper). ing.

そして、保持片５２にナット５３に合わせて挿通口５２ａが形成されるとともに、底板４２に挿通口４２ａが形成されて、該底板４２が保持片５２に支持された場合に、これらの挿通口４２ａ・５２ａが互いに一致するように配置されている。こうして、ボルト５４を底板４２と保持片５２の挿通口４２ａ・５２ａに上方から挿通してナット５３に螺挿することで、図３、図４に示すように、該底板４２を保持片５２に締結して、下方へ回動した状態に保持することができるようになっている。   The insertion holes 52a are formed in the holding piece 52 in accordance with the nuts 53, and the insertion holes 42a are formed in the bottom plate 42.

Thus, when the bottom plate 42 is rotated, the hook 59 is inserted into the receiving groove 58a of the receiving member 58, whereby the hook 59 is held by the receiving member 58 and the bottom plate 42 is rotated upward as shown in FIGS. It can be held in a moving state. However, the holding members 51 and 56 are not limited, and may be configured by bending a leaf spring or may be configured by providing a pivotable hook on the side plate 43.

そして、前記ダクト４０の下方にバッテリ６０が配置されて、該ダクト４０の底板４２の下方に位置するように旋回台７に支持されている。バッテリ６０は、底板４２が上方へ回動されて、ダクト４０の底部が開放された場合に、該ダクト４０内を通過できる大きさに構成されて、旋回台７に着脱可能とされている。但し、ダクト４０の下方にバッテリ６０の代わりに油圧機器などを配置することも可能である。   A battery 60 is disposed below the duct 40 and is supported by the swivel base 7 so as to be positioned below the bottom plate 42 of the duct 40. The battery 60 is configured to have a size that can pass through the inside of the duct 40 when the bottom plate 42 is rotated upward and the bottom portion of the duct 40 is opened, and is detachable from the swivel base 7. However, a hydraulic device or the like can be disposed below the duct 40 instead of the battery 60.

したがって、図３、図４に示すように、車両運転時などにダクト４０の底板４２を下方へ回動した状態に保持部材５１にて保持した場合には、該底板４２によりダクト４０の底部を構成して、ラジエータ３２冷却後の冷却風を前述のようにボンネット側壁１１ａの開口部１１ｂに向かって上向きに案内することができるとともに、バッテリ６０を上方から被覆して保護することができるようになっている。つまり、ダクト４０の一部である底板４２をバッテリカバーとして兼用することができるようになっている。   Therefore, as shown in FIGS. 3 and 4, when the bottom plate 42 of the duct 40 is held by the holding member 51 in a state where the bottom plate 42 is rotated downward when the vehicle is operated, the bottom portion of the duct 40 is held by the bottom plate 42. The cooling air after cooling the radiator 32 can be guided upward toward the opening 11b of the bonnet side wall 11a as described above, and the battery 60 can be covered and protected from above. It has become. That is, the bottom plate 42 which is a part of the duct 40 can be used as a battery cover.

また、図５、図６に示すように、メンテナンス時などにボンネット１１を取り外した後、ダクト４０の底板４２を上方に回動した状態に保持部材５６にて保持した場合には、該底板４２によりダクト４０の底部を開放し、該ダクト４０内を通じてその下方に配置したバッテリ６０を旋回台７から取り外したり、バッテリ６０を外部から旋回台７上まで運んで取り付けたりすることができるようになっている。   Further, as shown in FIGS. 5 and 6, when the bonnet 11 is removed during maintenance or the like and then the bottom plate 42 of the duct 40 is held by the holding member 56 in a state of being rotated upward, the bottom plate 42 is used.
