PROBLEM TO BE SOLVED: To provide an electric combine harvester improving work efficiency and reducing an environmental load by using an engine and actuators jointly as a drive source of a vehicle, using engine power only for a drive source of a threshing cylinder to obtain optimal power distribution, and efficiently installing the actuators for driving a travel part.SOLUTION: The vehicle is equipped with a prime mover and a battery. The battery supplies electric power to electric motors (the actuators) through inverters I1-I6, and the travel part of the vehicle and a working part including a plurality of handling parts are driven by the respective drive sources of the prime mover and electric motors. The travel part is driven by the power of the electric motors, and the working part includes an actuator driving part driven by the electric motors, and a prime mover driving part driven by the prime mover. The electric motors and the inverters I1-I6 driving the electric motors are installed in a draft air duct halfway part of cooling air introduced by a suction fan provided at the front part of the vehicle. A vehicle rear end at the terminal of a draft air duct is provided with an exhaust air port, and the inverters I1-I6 are cooled with the cooling air.COPYRIGHT: (C)2013,JPO&INPIT【課題】車両の駆動源にエンジンとアクチュエータを併用し、扱胴の駆動源のみをエンジン動力にし最適な動力配分とし、走行部を駆動させるアクチュエータを効率的に設置させ、作業効率の向上と環境負荷を軽減させた電動コンバインの提供。【解決手段】車両に原動機とバッテリーを搭載し、バッテリーは、インバータI1~I6を介して電動モータ(アクチュエータ)に電力を供給し、原動機と電動モータの各駆動源によって、車両の走行部と、複数の処理部からなる作業部とを駆動し、走行部は、電動モータの動力で駆動させ、作業部は、電動モータで駆動させるアクチュエータ駆動部と、原動機より駆動させる原動機駆動部とを備え、車両前部に設けた吸引ファンにより導入する冷却風の送風路中途部に電動モータおよびこの電動モータを駆動するインバータI1~I6を設置し、送風路終端の車両後端部に排風口を設け、冷却風によりインバータI1~I6を冷却させる。【選択図】図7
