[0065] The second air hole 127 is opened on the front side of the second box body 121 and communicates with the interior of the second storage tank 122 .

[0066] When the second box body 121 is in use, the movable rod 124 is used to guide the second box body 121. When the second box body 121 is pulled outward, the movable rod 124 is driven to move outward inside the first box body 111 until it moves to a suitable position, so that the second box body 121 can be rotated by the rotating rod 126. At this time, the first storage groove 112 inside the first box body 111 is completely exposed. At this time, the seedling soil ball is placed in the first storage groove 112, and the seedling cadre is extended outward through the first empty groove 113, and then the second box body 121 is rotated upward and pushed inward until the second box body 121 is reinserted into the movable groove 114. At this time, the seedling soil ball is in the first storage groove 112 and the second storage groove 122, and the seedling cadre is in the first empty groove 113 and the second empty groove 123. The first empty groove 113 and the second empty groove 123 can be used to limit the seedling cadre.

At this time, the upper first box 111 is placed above the connecting seat 211, and the clamping block 213 is plugged into the inner wall of the clamping groove 118, and the clamping block 213 is connected to the inner wall of the clamping groove 118 by bolts, then the three adjacent and stacked first boxes 111 are connected and limited to avoid movement during transportation. At the same time, its quick-connect connection method can be used to perform appropriate splicing combinations according to the on-site conditions, thereby greatly improving its scope of application.

[0072] Meanwhile, in the present embodiment, the first box 111 is stacked on two sides. In actual use, different stacking layers need to be set according to the height of the seedlings and the depth of the transport vehicle.

[0073] Specifically disclosed, the positioning assembly 22 includes:

[0074] A positioning plate 221, a mounting block 222 is fixedly mounted on the back of the positioning plate 221, and the mounting block 222 is fixedly connected to the bottom of the connecting seat 211 by bolts;

[0075] A positioning rod 223, the positioning rod 223 is movably inserted on the outer side of the positioning plate 221, and a stopper 224 is fixedly connected to the end of the positioning rod 223, and the back side of the stopper 224 is in contact with the first box body 111 without being squeezed;

[0089] By setting the limiting spring 2264 and the extrusion block 2265, the extrusion block 2265 is tightly pressed against the outer wall of the positioning disk 221 under the action of the limiting spring 2264, so that the rotating shaft 2261 and the rotating cylinder 2262 will not rotate at will. After the rotating cylinder 2262 is pulled outward, the extrusion block 2265 is separated from the outer wall of the positioning disk 221. At this time, the rotating cylinder 2262 can be rotated, which can drive the rotating shaft 2261 and the rotating block 2251 to rotate.
