ABSTRACT:
A seedling planting apparatus includes a carriage, a seedling supply device, a seedling picker device for picking seedlings from the seedling supply device at a predetermined picking position, and a seedling planting device for receiving the seedling from the seedling picker device at a predetermined delivery position and planting them in a field, the seedling supply device including a frame for supporting a seedling tray formed with multiple cells in which seedlings are grown, a traverse feeding mechanism for moving the frame transversely so that a selected cell is located at the predetermined picking position, and a longitudinal feeding mechanism for logitudinally feeding the seedling tray pitch by pitch when the frame is moved to a right or left terminal position thereof, the seedling picker device including a pair of seedling picker claws for picking the seedling from the cell and delivering it to the seedling planting device, and a seedling picker driving mechanism for moving the seedling picker claws from the predetermined picking position to the predetermined delivery position, the seedling picker driving mechanism being arranged such that the seedling picker claws are inserted into the cell at the predetermined picking position with a space between the leading ends thereof being slightly narrowed than the width of the upper end of the cell, and after the seedling picker claws are inserted, the seedling can be gripped by narrowing the space between the leading ends of the seedling picker claws, and the space between the leading ends of the seedling picker claws is widened at the predetermined delivery position. The thus constituted seedling planting apparatus can effect proper planting of seedlings with a mechanism of simple structure.
