Before placing the vegetables, a layer of storage film is first laid on the upper surface of the storage rack 2, and then the middle partition 3 is pressed on the storage rack 2 to position the storage film and press the edge of the storage film. The air pump is connected to the air extraction valve 25 in the air extraction mechanism to evacuate the air between the storage film and the partition groove 20 so that the storage film is sucked into the partition groove 20. At this time, the vegetables are evenly placed in the storage film in the partition groove 20, and then the middle partition 3 is picked up, and a layer of sealing film is laid again on the upper side of the storage film and the vegetables, and then the middle partition 3 is pressed on the storage rack 2, and a pressing plate 30 is placed on the upper side of the partition groove 20 to form a sealing and limiting effect on the vegetables in the partition groove 20, so as to avoid the vegetables from squeezing each other during transportation.

[0045] Specifically, the storage tank 61 is provided in the bottom shell 1, and refrigerated ice cubes are placed in the storage tank 61. The rotating handle 62 is used to control the rotation of the rotating disk 63, and then the locking rod 66 is controlled to extend or retract, so as to achieve the locking installation of the storage tank 61 in the bottom shell 1, ensuring that the storage tank 61 will not accidentally fall out of the bottom shell 1 during transportation. Through the arrangement of the air nozzle 26, the connecting conduit 68, the return conduit 69 and the circulating air pump, the low-temperature air in the bottom shell 1 can be circulated to the storage rack 2 of each layer, so as to keep the vegetables in the partition groove 20 fresh and refrigerated, further ensuring the freshness of the vegetables during transportation.

[0049] The working principle of the embodiment of the present invention is:

[0050] like Figure 1-Figure 17As shown, multiple groups of storage racks 2 are combined with the bottom shell 1 and the top cover 4 to form a storage space for storing vegetables. The middle partition 3 inside the storage rack 2 is used to divide the area to form a uniformly distributed grid. Before placing the vegetables, a layer of storage film is first laid on the upper surface of the storage rack 2, and then the middle partition 3 is pressed on the storage rack 2 to position the storage film and press the edge of the storage film. The air pump is connected to the air extraction valve 25 in the air extraction mechanism to evacuate the air between the storage film and the partition groove 20 so that the storage film is sucked into the partition groove 20. At this time, the vegetables are evenly placed in the storage film in the partition groove 20, and then the middle partition 3 is picked up, and a layer of sealing film is laid again on the upper side of the storage film and the vegetables, and then the middle partition 3 is pressed on the storage rack 2, and a pressing plate 30 is placed on the upper side of the partition groove 20 to form a sealing and limiting effect on the vegetables in the partition groove 20, so as to avoid the vegetables from squeezing each other during transportation. At the same time, the storage film has a shock-absorbing effect on the vegetables, further reducing the loss during transportation. In order to further preserve the vegetables and facilitate the removal of the vegetables from the partition groove 20 after transportation, the edge pressing groove 28 and the edge heating tube 33, the middle pressing groove 23 and the middle heating tube 31 realize the heating and bonding between the storage film and the sealing film, so that the storage film and the sealing film are bonded along the area division of the partition groove 20, and the vegetables are distributed in each storage area and sealed and packaged. At the same time, when taking out the vegetables, you only need to lift the edges of the storage film and the sealing film to take out all the vegetables in the partition groove 20 at one time, reducing the loss of vegetables and improving efficiency. The number of layers of the storage rack 2 is set according to the transportation requirements. The storage racks 2 are stacked by connecting the hooks 50 and the insertion holes 57 on the connecting rod 56. The setting of the tensioning spring 54 can make the storage racks 2 fit tightly together to avoid installation gaps. When disassembling the storage rack 2, it is only necessary to remove the connecting hook 50 from the insertion hole 57, and the connecting hook 50 is flipped to the upper side, so that the magnetic block 51 and the iron block are mutually attracted and abut against the side of the storage rack 2, so as to avoid the connecting hook 50 affecting the storage film and the sealing film when the storage rack 2 is moved. The storage slot 61 is set by the bottom shell 1, and refrigerated ice cubes are placed in the storage slot 61. The rotating handle 62 is combined to control the rotation of the rotating disk 63, and then the locking rod 66 is controlled to extend or retract, so as to realize the locking installation of the storage slot 61 in the bottom shell 1, and ensure that the storage slot 61 will not accidentally fall out of the bottom shell 1 during transportation. Through the setting of the air nozzle 26, the connecting conduit 68, the reflux conduit 69 and the circulating air pump, the low-temperature air in the bottom shell 1 can be circulated to each layer of the storage rack 2, so as to keep the vegetables in the partition slot 20 fresh and refrigerated, and further ensure the freshness of the vegetables during transportation.When the transport device needs to be stacked in the transport compartment, in order to facilitate quick stacking operations in the compartment, a connecting plate 70 is set on the side of the storage rack 2, and the push-pull handle 71 is engaged with the connecting plate 70 through the docking block 73, and the entire device is pushed to slide along the movable guide groove 40 on the top cover 4. When the pulley 11 falls into the positioning groove 41, the electric control button 72 on the push-pull handle 71 controls the stacking telescopic column 10 on the lower side of the bottom shell 1 to extend and dock with the stacking groove 42 on the top cover 4 of the device below, thereby ensuring that the entire device will not slide relative to each other during transportation, further ensuring the stability of the vegetables during transportation.
