PROBLEM TO BE SOLVED: To make it possible to improve efficiency of warming-up of an engine and increase an engine output thereby enhancing an operation efficiency of a service vehicle.SOLUTION: A radiator (50) is located outside an engine (E), a filter body (8B) for filtering dusts is located outside the radiator (50), a cooling fan (20) and a dust discharging fan (30), of which blade angles are so set as to be reverse to each other, are rotatably provided on a same axis between the engine (E) and the radiator (50), and a cooling clutch (C1) which connects and blocks transmission of a drive power from the engine (E) to the cooling fan (20) and a dust discharging clutch (C2) which connects and blocks transmission of a drive power from the engine (E) to the dust discharging fan (30) are provided. Further, drive state changeover means (45), which performs changeover between the state that the cooling clutch (C1) and the dust discharging clutch (C2) are exclusively connected to each other and the state that both of the cooling fan (C1) and the dust discharging fan (C2) are blocked, is provided.

    【課題】エンジンの暖気運転を効率化し、エンジン出力を高めて作業車輌の作業能率を向上させる。【解決手段】エンジン(E)の外側にラジエータ(50)を配置し、ラジエータ(50)の外側に塵埃を濾過する濾過体(8B)を配置し、エンジン(E)とラジエータ(50)の間には、互いの翼角度を逆に設定した冷却ファン(20)と排塵ファン(30)を同一軸心上に回転自在に設け、エンジン(E)から冷却ファン(20)への駆動力の伝達を接続および遮断する冷却クラッチ(C1)と、エンジン(E)から排塵ファン(30)への駆動力の伝達を接続および遮断する排塵クラッチ(C2)を設け、冷却クラッチ(C1)と排塵クラッチ(C2)を背反的に接続する状態と、冷却ファン(C1)と排塵クラッチ(C2)の両方を遮断する状態とに切り換える駆動状態切換手段(45)を設ける。【選択図】図10
