PROBLEM TO BE SOLVED: To provide an electric combine harvester which optimizes the power balance by setting a battery for feeding the electric power to an actuator, uses both an engine and the actuator as drive sources for a vehicle and using the drive source for a threshing cylinder only as the power of the engine, and improves the working efficiency and reduces environmental loads by efficiently setting the actuator for driving a travelling part.SOLUTION: In the electric combine harvester, a motor and the battery are mounted in the vehicle. The battery feeds the electric power to an electric motor (the actuator) via an invertor, and the travelling part of the vehicle including a crawler type travelling device and a working part including a plurality of treating parts are driven by respective drive sources of the motor and the electric motor. The travelling part is driven with the power of the electric motor. The working part includes an actuator drive part to be driven with the power of the electric motor, and a motor drive part to be driven with the power of the motor. Furthermore, an electric motor M6a is mounted inside a drive sprocket (a travelling wheel) 3a which constitutes the crawler type travelling device.COPYRIGHT: (C)2012,JPO&INPIT【課題】アクチュエータに電力を供給するバッテリーであって、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することで最適な動力配分とし、かつ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ることで作業効率の向上を図ると共に環境負荷を軽減させた電動コンバインを提供する。【解決手段】車両に原動機およびバッテリーを搭載し、バッテリーはインバータを介して電動モータ(アクチュエータ)に電力を供給すると共に、原動機および電動モータの各駆動源によって、クローラ式走行装置を備える車両の走行部と、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ると共に、作業部は電動モータの動力で駆動させるアクチュエータ駆動部と原動機の動力により駆動させる原動機駆動部とを備え、更にクローラ式走行装置を構成する駆動スプロケット(走行輪)3aに電動モータM6aを内設する。【選択図】図10
