Hooks (19) and (19) were fixed to the upper frame (14) of FIG. 8 on the opposite side to the projecting surfaces of the insertion rods (15) and (17). Further, each of these insertion rods is sized to fit into the opening at both ends of the outer vertical frame (1) and the inner vertical frames (1 ') (1').

Then, the two lower frames (13) and (13) are placed in parallel with their insertion rods (15 ') (16') and (17 ') facing upward. One of the rods (15 ') (17') is fitted with the lower end opening of the outer vertical frame (1) (1) of one outer ridge (6), and the other one of the outer ridges (6 ') is inserted into the other. ) Outside vertical frame (1) (1)
The lower end openings were fitted respectively. Further, the lower end openings of the inner vertical frames (1 ') and (1') of the inner support (11) were fitted into the center insertion rods (16 ') of the respective lower frames.
Also, upper frames (14) and (14) are inserted into upper end openings of the outer vertical frame (1) and the inner vertical frame (1 ') corresponding to the lower frames (13) and (13), respectively.
A seedling box storage rack having two rows of storage units (24) and (24) was assembled as shown in FIG. Since the constituent materials of the storage rack are all made of Al or Al alloy, they are lightweight and hard to rust. As shown in FIG. 9, through holes for bolts are opened in the upper end and the lower end of the vertical frame into which the insertion rods of the upper and lower frames are inserted, and nuts (23) are fixed by welding, and the wing bolts are inserted. By screwing in from the outside, the vertical frame and the upper and lower frames are integrated to make them robust and easy to handle.

The use of this rack will be described with reference to FIGS. The horizontal upper surface (2) of the outer receiving frame (4) of each step of the outer ridge (6) (6 ′) and the convex upper surface of the holding surface (9) of the inner receiving frame (10) of the corresponding step of the inner ridge (11) The empty height between the upper and lower sides of the receiving frame is the same as the height of the seedling box held in the seedling box held by the horizontal upper surface (2) and the convex upper surface of the holding surface (9). Height that does not hit the bottom of the seedling box. For example, to grow rice seedlings, as shown in the state of the right column of FIG.

And the holding surface (9) of the inner receiving frame (10) one step below the same level corresponding to the outer receiving frame (4), and the lower side surface of the seedling box (20) is The main body of the inner receiving frame (10) (2
By abutting on the side surface of 2) and placing it between the holding surface (9) and the ridge (8), it is stably held diagonally. The reason why the seedling box is held obliquely is that the root must be drained during the growth of the seedling. In this example, four seedling boxes (20) can be stored in one stage. Also, in order to prevent the seedling box (20) from dropping toward the front and back of the drawing in FIG. 10, Al is used as a vertical rod in the vertical rod insertion pipe (18) fixed to the upper frame (14) and the lower frame (13). A round pipe (21) was inserted.

After the seedlings have grown in the seedling box (20) in this manner, the seedlings are transported to a rice field. At this time, the seedling box (2
0) is to hold each stage horizontally as shown in the left side of FIG. 10, so that the seedling box (20) has the horizontal upper surface (2) of the outer receiving frame (4) and the inner receiving frame as shown in FIGS. It is supported by the holding surface (9) and the convex upper surface of (10). Seedling box (20) in this state
On the side of the outer receiving frame (4), a vertical ridge (7) of the receiving frame (4) is
On the inner receiving frame (10) side, the ridges (8) of the receiving frame (10) prevent lateral sliding of the seedling box (20). In addition, the pipe is prevented from falling off in the front-rear direction by the round pipe (21). The rack containing a large number of seedling boxes (20) held horizontally in this manner is lifted by the hooks (19) at the upper end, placed on the bed of a light truck, transported to rice fields, and with the rack placed on the bed. However, by removing the round pipe (21), the seedling box (20) can be taken out from the front-back direction and from the outside of the outer ridge (6).

[0012]

As described above, according to the present invention, the bottom surface of the edge of the seedling box is always kept flat when the seedling box is stored and held in each stage of the rack, so that it is stable. Also, when the seedling box is held at an angle during the growth of the seedling, mechanical adjustment of the frame or the like is unnecessary as in the related art, and the handling is easy. Further, when there is only one inner support, the number of storage units is two. However, by using two or more inner supports, the number of storage units can be easily increased to three or more. The housing and the outer housing can be easily disassembled to save storage space.
