10. A cold-chain logistics transportation vegetable cold insulation box comprises the following steps:

s1, when the vegetable cold insulation box is used, firstly, water is injected into a water storage chamber (4) through a water injection pipe at the upper end of a storage box (1), then a second annular plate (14) and a third annular plate (19) on two placing plates (9) are respectively adjusted according to the height of vegetables, a hemispherical plate (21) at the lower end of the third annular plate (19) is pressed downwards, the hemispherical plate (21) drives the fixedly connected third annular plate (19) to move downwards, the third annular plate (19) drives a second fixedly connected sliding block (18) to slide downwards in a second sliding groove (16), so that a second fixedly connected overlapping block (20) at two sides is driven to move to the lower side of a second clamping block (17) at two sides, the second annular plate (14) is driven to move downwards when the second sliding blocks (18) at two sides slide to the lower ends of the second sliding grooves (16) at two sides, the second annular plate (14) drives a first fixedly connected sliding block (13) at two sides to slide downwards in the first sliding grooves (11) at two sides, the second ring plate (14) drives the first lapping blocks (15) fixedly connected with the two sides to move to the lower sides of the first clamping blocks (12) on the two sides, so that longer vegetables can be placed, then the placing plate (9) is placed in the storage box (1) and lapped on the lapping strips (8) fixedly connected with the two side walls, and therefore the vegetables can be placed in layers;

s2, when the vegetables in the cold insulation box are refrigerated, the box cover (23) is firstly turned to the left, after the sealing ring (24) seals the opening at the front end of the storage box (1), a strong magnetic strip (25) on the box cover (23) is adsorbed on the storage box (1) through magnetic force to enable the interior of the storage box (1) to be in a sealing state, a plug of a power cord (39) on the storage box (1) is electrically connected with an external power supply, then a control switch I (22) is used for controlling the water pump (7) to pump water, the pumped water is pumped into the curved pipe (5) through the pressurization of the water pump (7), finally, the vegetable frost is sprayed from the plurality of atomizing nozzles and evenly sprinkled on the surface of the placed vegetables, then the compressor (6) is controlled to work through the control switch I (22), and the compressor (6) controls the condenser (3) to cool, so that frost is hung on each vegetable, and the storage effect is improved;

s3, when the cold insulation box needs to be transferred and transported, the storage box (1) is placed on the upper surface of the moving plate (35), the transfer plate (26) is pushed to move to the transport vehicle, then the motor (29) is controlled to drive the first fixedly connected bevel gear (30) to rotate through the second control switch (40), the first bevel gear (30) drives the second meshed bevel gear (33) to rotate, the second bevel gear (33) drives the fixedly connected threaded rod (32) to rotate, the threaded rod (32) is in threaded connection with the threaded sleeve (34), so that the storage box (1) placed on the moving plate (35) is driven to move upwards, when the threaded sleeve (34) moves to the top, workers standing on the vehicle transfer the storage box (1) into a vehicle hopper, and then the power line (39) is electrically connected with the vehicle-mounted power supply, and therefore labor and time are saved.
