The utility model relates to a seedling transplanting machine, which is provided with a seedling planting device (U), a seedling supplying device (K) and an expansion hole excavating mechanism (130), wherein the seedling planting device (U) is arranged on a movable machine body (T) and provided with a seedling planting appliance (U1); the seedling supplying device (K) is used for supplying seedlings (N) to the seedling planting appliance (U1); the expansion hole excavating mechanism (130) is used for forming expansion holes (W2) in ridges (R); the expansion hole excavating mechanism (130) is provided with a support rod (132) and a hoeing part (131); the front part of the support rod (132) is pivoted with the movable machine body (T) and moves vertically when the seedling planting appliance (U1) moves vertically; the hoeing part (131) is arranged at the rear part of the support rod (132) and rushes into the ridges (R) when the support rod (132) moves downwards so as to form the expansion holes (W2) from rear of the predetermined position of a seedling planting hole (W1) to front; the hoeing part (131) is provided with left and right wing parts (131L, 131R) and a grabbing part (131S); the left and right wing parts (131L, 131R) rush into the ridges (R) and put ridge soil to left and right sides from the center; the grabbing part (131S) is arranged at the lower parts of the left and right wing parts (131L, 131R) and used for grabbing ridge soil. By adopting the seedling transplanting machine disclosed by the utility model, the resistance to ridge soil can be reduced while the expansion holes are excavated; in addition, soil cannot be stayed at the front parts of the expansion holes while moving upwards from the ridges. |
