Background
Conventionally, there has been known a seeding machine including a conveying device that conveys a seedling box and a seeding portion that seeds to a bed soil of the seedling box conveyed by the conveying device. The seed sowing portion has a delivery roller that has a recessed portion into which the seed enters on an outer peripheral surface and that is rotated about a rotation axis extending in a lateral direction orthogonal to a conveying direction of the conveying device in a plan view, thereby delivering the seed in the recessed portion. In the case of the conventional sowing machine, since the seeds in the concave portion are released from a high height position above the seedling box, the falling height of the seeds is high and the time for which the seeds in the falling process are subjected to air resistance is long. Therefore, the position (sowing position) of the seeds on the bed soil of the seedling box is likely to be uneven.
