Therefore, when the seedling is transferred from the lower end of the conveyor belt 9a 9a of the seedling transfer guide device 9 to the transplant nail 11, the posture of the seedling is not disturbed, and the root portion of the seedling is kept in the lower position. The seedlings can be delivered within 11.

a opens to discharge the pot seedlings in the transplanted nail 11 into the soil, and after the end of planting in which the pot seedlings in the transplanted nail 11 have been discharged, the transplanted nail 11 reaches the top dead center position. When moved, the split transplant claws 11a, 11 are caused by contact between the rollers 22, 22 and the narrow portions on both end surfaces of the cam 24.
a is closed.

This is because it is possible to prevent the part 12 from interfering with the planting posture of the seedlings.

2, the transplanting claw 11 is disposed behind the drive unit 12 in the advancing direction of the transplanting machine to support the transplanting claw 11 so as to be drivable along the planting track, and to receive the seedling in the planting track of the transplanting claw 11. Since the guide drop end portion of the seedling receiving and guiding device 9 that receives and guides the seedlings supplied from the seedling feeding device to the transplant nail 11 is located above the position, the transplant nail driving portion 12 is provided.
Is always preceded by the transplanted nail 11 to prevent the transplanted nail drive part 12 from interfering with the seedlings transplanted by the transplanted nail 11 to deteriorate the seedling planting posture. The seedling can be done well.
