This creation relates to the structure of a tray machine for a seedling tray arrangement device, especially a tray machine structure provided at the front end of the nursery tray arrangement device to provide tray operation. It is mainly composed of a rack, an end plate mechanism and a conveying mechanism. The end frame mechanism is composed of a linkage shaft, a connecting rod, a claw rod and an end disk motor. The linkage shaft system is pivotally arranged above the frame and linked. A link is connected to each of the two ends of the shaft, and a claw lever having an end disc claw is pivotally connected to the lower end of the link, and a sprocket is connected to the end disc motor on the linkage shaft, which is driven and controlled by the end disc motor； The conveying mechanism is arranged below the frame, and there is another movable part at the front end of the conveying mechanism. There are several pulleys on the two side frames below the frame and the two sides of the movable part, and each set is provided with a conveying belt. A sprocket is connected to the conveying motor on the wheel rod of the pulley below the frame, and the conveyer is controlled by the conveying motor.本創作係有關一種育苗盤排列裝置之分盤機結構，尤指一種設置於該育苗盤排列裝置前端，提供分盤作業之分盤機結構，其主要係由機架、端盤機構及輸送機構所構成；該機架係跨設於育苗盤排列裝置之前端，而端盤機構係由連動軸、連桿、爪桿及端盤馬達構成，該連動軸係樞設於機架之上方，連動軸之二端各連接有一連桿，連桿之下端再各樞接一具有端盤爪之爪桿，而該連動軸上設有鏈輪與端盤馬達連結，而受端盤馬達驅動控制；該輸送機構係設於機架之下方，輸送機構之前端另設有一活動部，於機架下方之二側架體上及活動部之二側各設有數個皮帶輪，並各套設有輸送皮帶，而機架下方皮帶輪之輪桿上設有鏈輪與輸送馬達連結，藉輸送馬達控制輸送皮帶作動者。
