Is configured to convey, the transport terminal end of the sowing work process of this transport device, while continuing the seedling box transport in the same direction following the transport direction in the seeding work process, Providing a nursery box orientation changing device that switches the short side direction in the nursery box along the traveling direction, and further, the lateral width of the transport surface on which the nursery box of the transport device is mounted and transported, the short side of the nursery box. It is wider than the length in the direction and narrower than the length in the long side direction of the seedling raising box.

[Action]

In other words, the seeding work process is performed while the seedling raising box is being conveyed in a state where the long side direction is along the traveling direction by the conveying device, and the seedling raising direction is changed by the seedling raising box changing device at the conveying end portion of the conveying device. The seeded seedling raising box is automatically inverted so that the short side direction is along the traveling direction while continuing the feeding of the seedling raising box in the same direction as in the feeding direction.

In addition, the lateral width of the transport surface for placing and transporting the nursery box of the transport device is wider than the length in the short side direction of the nursery box, and
Since the width of the nursery box is set narrower than the length in the long side direction, during the sowing process, the nursery box is stored within the width of the transport device and transported while avoiding contact with other things. Therefore, at the transport end portion of the transport device, both short sides of the seedling raising box protrude from both lateral sides of the transport device.

[Effect of device]

Therefore, during the seeding work process, smooth transportation can be performed while avoiding transportation irregularity or defective transportation due to being caught in the lateral soil width direction of the nursery box with the bed soil supply device or the like. Further, in the transfer end portion of the transfer device, the seedling raising box can be put into a state in which both short sides thereof protrude from both lateral sides of the transfer device without the need for artificial reversing work.
It is possible to easily perform a picking-up work and a transferring work in which both short sides are lifted with hands, and at the same time, the work can be smoothly transferred to the next working device with the short side direction being the traveling direction.

Moreover, in the sowing work process, since the seedling raising box is transported with the long side along the traveling direction, the bed soil supply device etc. required for the seeding work has a short width that matches the short side length of the seedling raising box. Anything can be used, and the more compact it is.
