A seedling thrower comprises a rack (1), a first drive device (2), and a seedling and seedling tray conveying device (3), a seedling taking device (4), a seedling conveying device (5), and a seedling throwing device (6) that are provided on the rack. The seedling and seedling tray conveying device comprises a conveying group (31) of which the tail end is connected to the first drive device. The seedling taking device comprises several first drive belt groups (41) of which the start ends are connected to the first drive device and seedling gripping devices (42). Each of the seedling gripping devices is disposed between adjacent first drive belt groups. The seedling conveying device comprises several second drive belt groups (51) of which the axes are parallel to the axes of the first drive belt groups in a direction vertical to the travelling direction of the seedling thrower. The start end of the seedling conveying device is connected to the first drive device. The seedling throwing device comprises a second drive device (61) and several third drive belt groups (62). The start ends of the third drive belt groups are disposed beneath the tail ends of the second drive belt groups. The seedling thrower is highly automated and can greatly improve production efficiency.Linvention concerne un lanceur de semis qui comprend un bâti (1), un premier dispositif dentraînement (2), et un dispositif de transport de semis et de plateau de semis (3), un dispositif de prélèvement de semis (4), un dispositif de transport de semis (5) et un dispositif de lancer de semis (6) qui sont disposés sur le bâti.
