Abstract
Description
<作業機械>
図1は、本実施形態に係る作業機械1を模式的に示す側面図である。図2は、本実施形態に係る作業機械1を模式的に示す後面図である。本実施形態においては、作業機械1が油圧ショベルであることとする。
図3は、本実施形態に係る作業機械1の排気構造を模式的に示す後面図である。図4は、本実施形態に係る作業機械1の排気構造を模式的に示す断面図であり、図3のA−A線断面矢視図に相当する。
次に、本実施形態に係る作業機械1の動作について説明する。エンジン13の駆動により、冷却ファン12が回転し、油圧ポンプ14が駆動する。冷却ファン12が回転することにより、区画部材8の外部空間の空気CAが吸気口9を介してエンジンルーム7に流入する。エンジンルーム7に流入した空気CAは、クーリング装置11を通過した後、冷却ファン12に流入する。
以上説明したように、本実施形態によれば、エンジンルーム7に排気ダクト20が設けられるので、エンジンルーム7において暖められた空気CAは、排気ダクト20を介して区画部材8の外部空間に円滑に排出される。そのため、エンジンルーム7の温度上昇が抑制される。
第2実施形態について説明する。上述の実施形態と同一又は同等の構成要素については同一の符号を付し、その説明を簡略又は省略する。
上述の実施形態において、吸音材30は設けられなくてもよい。
