Since the rail 28 is also inclined and forms a sloped surface, the storage box 3 flows under its own weight and falls onto the conveyor 34. Add soil between each bot 2 of paper pot paper 1 in the remaining seedling raising box.

The storage box 3 is located at the terminal end 35 of the conveyor 34 (transfer table 7
automatically returns to the starting point). In the conventional type, there is no device after the end of the transport conveyor 34, so the leading end of the storage box 3 falls onto the floor, and the rear end of the storage box 3 does not reach the end of the transport conveyor 34 at any time. In some cases, the particles may remain in the storage box 3, obstructing the movement of the next storage box 3. Therefore, a worker is always there and picks up the boxes one after another and transports them to the work site.However, in the present invention, the storage boxes 3 transported by the transport conveyor 34 are placed at the terminal end 5 of the transport conveyor 34.
When this occurs, the engagement plate U engages with the upright wall 4 of the storage box 3 and moves the storage box 3 upward.

Therefore, at approximately the center position of the frame r in the transport direction,
The lower end of the support arm 45 protruding upward is fixed, and the support arm 4
