If the seedling raising box 1 is transferred by the first conveyor device 5 while jetting water from the nozzle 22 group, the seedling raising box 1 will first pass through the soil filling device 3 without being filled with soil. Part conveyor mechanism 16
The water is transferred into the irrigation system 4 by. In the irrigation device 4, water is first sprayed directly from the nozzle 22 group of the front irrigation section 20 onto the top and side surfaces of the seedling box 1, and the water sprayed into the seedling box 1 is The seedling box 1 is passed through the numerous holes 1a at the bottom of the box.
It also reaches the bottom side of the . In this way, water is applied to the entire inner and outer surfaces of the seedling nursery box 1,
This weakens the adhesion of mud, fertilizer, etc. adhering to the inner and outer surfaces. Next, the cleaning rotating brush group 24 rotated in the direction of the arrow comes into sliding contact with the inner and outer surfaces of the seedling-raising box 1. To explain this in detail, the upper rotating brush 26 is rotated on the inner and outer surfaces of the seedling-raising box 1, and on both sides. The lower rotating brush 27 is in sliding contact with the lower side of the seedling box 1, and the side rotating brush 28 is in sliding contact with the upper side of the side surface of the seedling box 1, on the front and rear upper edges of the box 1, and removes muddy soil, fertilizer, etc. with weakened adhesion for seedlings. It is rubbed off from the inner and outer surfaces of the box 1, and finally mud, fertilizer, etc. are washed away from the inner and outer surfaces of the seedling raising box 1 by water jetted from the nozzle 22 group of the rear irrigation section 20. In this way, while the seedling raising box 1 passes through the irrigation device 4, the water sprayed from the nozzle groups 22 of both irrigation parts 20 and the rotary cleaning brush group 24 that are rotationally driven cooperate with each other to make the seedling raising box 1 is cleaned on its inner and outer surfaces. The cleaned seedling growing box 1 is then transferred to the rear side of the irrigation device 4 by the rear conveyor mechanism 17.

In addition, in the embodiment, the upper rotating brush that comes into sliding contact with the inner surface of the seedling growing box can be moved largely upward from the transfer path of the seedling growing box, but it is not necessary to allow such a large positional change. ,
The upper rotating brush may be repositioned to the outside of the transfer path of the seedling growing box to the extent that at least a slight gap can be formed between the bed soil of the seedling growing box and the upper rotating brush during irrigation. Further, the position of the upper rotating brush may be changed by removing the upper rotating brush from the support frame. Furthermore, other rotary brushes other than the upper rotary brush may also be repositioned to the outside of the transfer path of the seedling nursery box.

As described in detail in the embodiments above, the present invention includes a irrigation device equipped with a group of cleaning rotating brushes that come into sliding contact with the inner and outer surfaces of the seedling growing box. Since the position of the irrigation device can be changed to the outside of the transport path of the box, it is possible to use the irrigation device not only as a device for irrigating the bed soil of the seedling box, but also as a device for cleaning the seedling box. can also be used. In addition, the manufacturing cost is much lower than the combined manufacturing cost of a conventional irrigation device and a dedicated machine for cleaning seedling boxes, and the burden on seedling growers can be significantly reduced compared to the conventional method.
