摘　　要：为实现穴盘苗移栽全自动化，在自制的穴盘苗自动移栽机上设计了苗盘自动回收机构。该机构主要由输送带、托举凸轮、限位块和集盘架组成。取苗完成后的苗盘以一定的倾角下落至输送带上，再输送至集盘架下方，由托举凸轮托举苗盘至集盘架内的限位块上，以完成自动回收。苗盘的下落倾角β、托举凸轮的轮廓半径R和转速n是实现苗盘自动回收的主要影响因素。单因素试验结果表明，苗盘下落倾角β为55°-65°，托举凸轮的轮廓半径R为120～160mm，托举凸轮转速为30～120r／min，可实现苗盘自动回收。多因素正交试验结果表明，苗盘的下落倾角β为60°，托举凸轮轮廓半径R为140mm，凸轮转速n为30r／min，是实现苗盘的自动回收较佳组合。To realize the full automation of seedling transplanting, the automatic recovery mechanism of seedling tray was designed based on the homemade seedling transplanting machine. The mechanism is mainly composed of a conveyer belt, lifting cam, a limit block and a set of plate frame. The seedling tray fell to the conveyer belt in a certain angle after the seedling was recovered, then transported to the plate frame by the conveyer belt, and finally lifted to the limit block that is in the plate frame to complete the automatic recovery which was mainly influenced by the falling angle of seedling tray β, the radius of lift cam R and the speed of revolution n. Through single factor test seedling plate falling angle β of 550-65°, cam profile radius of lifting R of 120-160 mm, and the cam speed n of 30-120 r/min were obtained. Through multi factor orthogonal test the best combination with seedling plate falling angle β being 60°, cam profile radius of lifting R being 140 mm, and cam speed n being 30 r/min was obtained.
