Summary:To provide a crop harvesting machine that can reliably convey crops while preventing damage thereof.SOLUTION: A crop harvesting machine conveys and harvests crops of an agricultural field. This crop harvesting machine comprises a first conveyance unit and a second conveyance unit 22. The first conveyance unit conveys the crops. The second conveyance unit 22 conveys the crops conveyed by the first conveyance unit, along the conveyance direction directing obliquely upward. The second conveyance unit 22 includes a downside conveyor 22b and a topside conveyor 22 t. The downside conveyor 22b conveys the crops in the conveyance direction while supporting the crops from the underside. The topside conveyor 22 t is provided in such a manner that it is opposed to the downside conveyor 22b, and assists the conveyance of the crops by the downside conveyor 22b. The topside conveyor 22 t comprises a conveyance auxiliary unit 64 having at least one or more elastically deformable protrusions 63. Each protrusion 63 can move to the downstream side of the conveyance direction while coming in contact with the crops conveyed by the downside conveyor 22b.SELECTED DRAWING: Figure 2 【課題】農作物の損傷を抑制しながら確実に搬送できる農作物収穫作業機を提供する。【解決手段】農作物収穫作業機は、圃場の農作物を搬送して収穫する。この農作物収穫作業機は、第1搬送部と、第2搬送部22と、を備える。第1搬送部は、農作物を搬送する。第2搬送部22は、第1搬送部により搬送された農作物を、斜め上方へ向く搬送方向に沿って搬送する。第2搬送部22は、下側コンベア22bと、上側コンベア22tと、を備える。下側コンベア22bは、農作物を下側から支えながら搬送方向に搬送する。上側コンベア22tは、下側コンベア22bに対向するように設けられ、下側コンベア22bによる農作物の搬送を補助する。上側コンベア22tは、弾性変形可能な少なくとも1以上の凸部63を有する搬送補助部64を備える。それぞれの凸部63は、下側コンベア22bにより搬送される農作物に接触しながら搬送方向の下流側へ移動可能である。【選択図】図2
