To enhance working efficiency by preventing overheat and power reduction of an engine by highly efficiently blowing an outside air flow sucked by normal rotation of a fan, toward the engine.SOLUTION: A structure of a prime mover of a combine-harvester includes: a fan (45) between an engine (E) and a radiator (30), the fan, in a normal rotation state, sucking an outside air from the outside of a cover (9) to the inside of an engine room (6), and, in a reverse rotation state, blowing an inside air from the inside to the outside of the cover (9); and a hydraulic motor (50) for driving the fan (45) by oil transfer from the hydraulic pump (62) driven by the engine (E), the hydraulic motor (50) being disposed at a part outside the radiator (30) in axial-directional view of a rotary shaft (46) of the fan (45). Further, in the axial-directional view of the rotary shaft (46) of the fan (45), the hydraulic motor (50) is disposed at a part outside a cooler such as an oil cooler (31) and an intercooler (36).SELECTED DRAWING: Figure 3
【課題】ファンの正転によって吸引した外気の流れをエンジンに向けて効率良く送風して、エンジンのオーバーヒートや出力低下を防ぎ、作業能率を高める。【解決手段】エンジン(E)とラジエータ(30)の間に、正転状態では外気をカバー(9)の外側からエンジンルーム(6)内に吸引し、逆転状態では内気をカバー(9)の内側から外側へ送風するファン(45)を設け、エンジン(E)で駆動される油圧ポンプ(62)からの送油によってファン(45)を駆動する油圧モータ(50)を設け、ファン(45)の回転軸(46)の軸心方向視において、油圧モータ(50)をラジエータ(30)の外側の部位に配置する。また、ファン(45)の回転軸(46)の軸心方向視において、油圧モータ(50)をオイルクーラ(31)やインタクーラ(36)等の冷却器の外側の部位に配置する。【選択図】 図3
