PROBLEM TO BE SOLVED: To provide a combine in which an operator is quickly informed of an overload of an electric motor to prevent the occurrence of serious failure, in a configuration of driving a feed chain of a threshing device by the electric motor.SOLUTION: A combine is driven by a conveyance drive motor 4 where a feed chain 5 of a threshing device mounted in the combine is rotated and controlled by a conveyance inverter 3. The combine is provided with a rotational speed sensor 6 for measuring a drive rotational speed of the conveyance drive motor 4 and a monitoring unit 7 for receiving and monitoring each detection signal of a wattmeter 2 for measuring a load current. A control unit 8 is also provided which decides whether or not a load current value to the rotational speed of the conveyance drive motor 4 is proper, and operates notification means 9 to an operator when being overloaded.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】脱穀装置のフィードチェンを電動モータで駆動する構成で、電動モータの過負荷を操縦者にいち早く知らせて重大な故障に至らないようにするコンバインを提供する。【解決手段】コンバインに搭載した脱穀装置のフィードチェン５を搬送インバータ３で回転制御する搬送駆動モータ４で駆動するコンバインにおいて、搬送駆動モータ４の駆動回転速度を計測する回転速センサ６と負荷電流を計測する電力計２の各検出信号を受けて監視する監視部７を設け、搬送駆動モータ４の回転速度に対する負荷電流値が適正か判断して過負荷となると操縦者に対する報知手段９を作動する制御部８を設けた。【選択図】図１
