[0031] When using this utility model:

[0032] Working principle: When the height of the cultivation box 2 needs to be adjusted according to the rice growth, pull the pull plate 309 to move the connecting rod 306, which in turn stretches the return spring 310. Simultaneously, the connecting plate 307 moves, causing the insertion rod 308 to move out of the insertion hole 302. Pulling the handle 305 moves the concave frame 304, causing the slider 303 to slide outside the sliding rod 301. At the same time, the limiting block 313 slides outside the limiting rod 312, changing the height of the cultivation box 2. Then, align the insertion rod 308 with the insertion hole 302. Loosening the pull plate 309 allows the return spring 310 to reset, causing the pull plate 309 to move the connecting rod 306 back to its original position. This allows the insertion rod 308 to be embedded in the insertion hole 302, completing the fixation and facilitating the adjustment of the cultivation box 2. When the incubation box 2 needs to be replaced, pull the incubation box 2 to move the insert 406, so that the inclined surface of the slot 407 presses against the inclined surface of the block 405, causing the block 405 to retract into the shrinkage cavity 402, thereby disassembling the incubation box 2 and unloading the cultivated rice. Then, install the empty incubation box 2. During installation, by embedding the insert 406 into the slot 401, the inclined surface of the block 405 is pressed, causing the block 405 to drive the moving plate 404 to move and press against the connecting spring 403. When the block 405 is aligned with the slot 407, the resetting of the connecting spring 403 causes the block 405 to be embedded in the slot 407, fixing the insert 406, thus completing the installation of the incubation box 2.
