A multi-screen screening machine for crops, comprising a feeding mechanism, a conveying mechanism, a sorting mechanism and a screening device. The feeding mechanism can pick out the crops one by one and transfer them to the conveying mechanism, and is transported through a plurality of sorting sections. The classification mechanism includes a plurality of air valves respectively corresponding to the classification sections, and the screening device can capture the images of the crops transferred by the conveying mechanism, and can identify the classification intervals corresponding to each crop according to the built-in image parameters, and control The valves are actuated to spray the crop into the corresponding classification interval. Through the cooperation of the feeding mechanism and the conveying mechanism, the crops are sorted one by one for the screening device to identify and screen the structural design, which can automatically sort and classify a variety of crops, which can greatly save the screening time and manpower.一種農作物多篩選別機，包含一進料機構、一輸送機構、一分類機構與一篩選裝置。進料機構能將農作物逐一揀出並移送釋出到輸送機構，而被輸送通過多個分類區間。分類機構包括多個分別與該等分類區間對應之氣閥，篩選裝置能擷取輸送機構移送通過之農作物的影像，並能根據內建之影像參數識別出每一作物對應之分類區間，並控制該等氣閥之作動，以將農作物噴入對應之分類區間。透過進料機構與輸送機構相配合將農作物逐一揀出以供篩選裝置進行識別篩選的結構設計，能對一種農作物進行多種級別的自動化篩選分級，可大幅節省篩選分類時間與人力。
