One end of the support rod (506) located inside the support bin (504) is fixedly connected to one side of the support block (505), and the outer wall of the support rod (506) is threadedly connected to the inner wall of the fixed block (507), and the outer wall of the fixed block (507) is movably in contact with the outer wall of the support bin (504).

7. The vegetable transport device for a vegetable greenhouse according to claim 6, characterized in that: The feeding structure (6) comprises a protective bin (601), a torsion spring (602), a feeding rod (603) and a feeding plate (604); one side of the protective bin (601) is fixedly connected to the outer wall of the feeding bin (102); the inner wall of the protective bin (601) is fixedly connected to one end of the torsion spring (602); the other end of the torsion spring (602) is fixedly connected to the inner wall of the feeding rod (603); one end of the feeding rod (603) passes through the back of the feeding bin (102) and extends to the front of the feeding bin (102); the outer wall of the feeding rod (603) located inside the feeding bin (102) is snap-connected to the inner wall of the feeding plate (604); the outer wall of the feeding plate (604) is in sliding contact with the inner wall of the feeding bin (102).

8. The method for using the vegetable transport device for a vegetable greenhouse according to claim 1 comprises the following steps: S1: Start the compressor (201). The compressor (201) can pressurize the refrigerant in the liquid storage bin (202) and guide it to the condensing bin (203). The low temperature is then conducted to the heat transfer bin (103) through the refrigeration pipe (204), so that the heat transfer bin (103) cools the interior of the heat preservation box (101). Vegetables are put into the feed bin (102). Under the action of gravity, the feed plate (604) rotates in the feed bin (102) through the feed rod (603), so that the vegetables enter the storage bin (503). The feed plate (604) is reset under the reset action of the torsion spring (602), so that the heat preservation box (101) forms a closed space, thereby completing the work of preserving the vegetables. S2: After being transported to a designated location, the sealed door (404) is rotated, and the sealed door (404) drives the flip rod (402) to rotate via the flip block (403), and the flip rod (402) drives the upper rack (306) to slide via the flip gear (401), and the upper rack (306) drives the lower rack (307) to slide via the push block (305), and the lower rack (307) drives the linkage gear (501) to rotate under the meshing force, and the linkage gear (501) rotates the storage bin (503) out of the heat preservation box (101) via the linkage rod (502), so that the user can take the vegetables conveniently; S3: When the storage bin (503) is rotated out of the heat preservation box (101), the linkage rod (502) rotates with the support bin (504) at the same time, and the support block (505) is pulled out of the support bin (504), and the top of the support block (505) is brought into contact with the inner wall of the sealing door (404). The fixing block (507) is rotated to make the fixing block (507) contact with the outer wall of the support bin (504), thereby completing the positioning of the support block (505). At the same time, the threaded block (304) is rotated, and the outer wall of the threaded block (304) contacts with the outer wall of the positioning bin (301) under the meshing force of the threads, thereby preventing the opened sealing door (404) from being reset under the action of gravity and causing damage to the staff who are taking the vegetables.
