PROBLEM TO BE SOLVED: To provide a crop harvester capable of suppressing an occurrence of a problem in a conveyance device for conveying a container from an upstream side storage part to a downstream side storage part in a storage base.SOLUTION: A container conveyance device 28 of a crop harvester is provided with an electric motor 28a, a drive shaft 48 driven by the electric motor 28a, and a push part 50a driven in conjunction with the drive shaft 48 capable of sending a container. The crop harvester is provided with a drive control part 68 for driving and controlling the electric motor 28a when a first presence/absence sensor 51 is brought into a detection state in a case where a second presence/absence sensor 54 is in a non-detection state, and a forced stop part 71 for forcibly stopping power supply to the electric motor 28a when a rotation speed of the push part 50a is a rotation speed equal to or lower than a predetermined rotation speed in a state that the drive control part 68 is outputting a drive command to the electric motor 28a.SELECTED DRAWING: Figure 12COPYRIGHT: (C)2018,JPO&INPIT【課題】収容台において上手側収容部から下手側収容部にコンテナを搬送する搬送装置に不具合が生じることを抑止できる作物収穫機を提供する。【解決手段】コンテナ搬送装置28に、電動モータ28aと、電動モータ28aにより駆動される駆動軸48と、駆動軸48に連動駆動されてコンテナを送り出し可能な押し部50aと、が備えられ、第2存否センサ54が非検出状態である場合に第1存否センサ51が検出状態になると電動モータ28aを駆動制御する駆動制御部68と、駆動制御部68が電動モータ28aに駆動指令を出力している状態で押し部50aの回転速度が所定回転速度以下の回転速度であると、電動モータ28aへの電力供給を強制的に停止させる強制停止部71と、が備えられている。【選択図】図12
