[0032] Embodiment:
[0033] The present application is described below taking the transportation of rape as an example.
[0034] For example, as shown in FIG. 1, the fresh-keeping outer box 2 is provided with a heat preservation cover 1, and the heat preservation cover 1 is provided with a handle 11. Figures 1 to 8As shown, the modified gas preservation logistics box comprises a preservation outer box 2 and a preservation inner box 4, the preservation inner box 4 is arranged in the preservation outer box 2, and the preservation inner box 4 and the preservation outer box 2 are filled with a heat preservation filler 3. The double-layer design of the preservation outer box 2 and the preservation inner box 4, combined with the filling of the heat preservation filler 3, effectively improves the heat preservation performance of the logistics box and ensures the stability of the temperature in the box, which is beneficial to prolong the preservation period. A limiting baffle 14 is fixed on the inner wall of the preservation inner box 4 near the bottom position, which is used to support the detachable bottom plate 5. The limiting baffle 14 is placed on the detachable bottom plate 5, which is used to support the rapeseed placed in the preservation inner box 4. The bottom plate 5 is used to place ice blocks and ice bags for cooling and preservation. A plurality of grooves 52 are uniformly arranged in the bottom plate 5, which are used for air flow in the box. At the same time, the cold air of the ice blocks and ice bags can flow upward into the preservation inner box 4 to cool the rapeseed. A plurality of vertical structure partitions 6 are fixed on the upper side of the bottom plate 5, which increase the utilization rate of the space in the box and can separate the rapeseed to avoid damage caused by extrusion between the rapeseed. A detachable heat preservation cover 1 is arranged on the upper side of the preservation outer box 2, which not only enhances the sealing performance of the box, but also improves the heat preservation performance of the logistics box. An inflation nozzle 9 and an exhaust valve 10 are arranged on the right side of the preservation outer box 2. The inflation nozzle 9 is connected to the inside of the preservation inner box 4 through an inflation pipe 8, which is used to inflate the required gas such as nitrogen and carbon dioxide into the box to adjust the gas environment in the box. The exhaust valve 10 is connected to the inside of the preservation inner box 4 through an exhaust pipe 7, which is used to exhaust the gas in the box to maintain the stability of the gas environment in the box. This design solves the problems of large volume, high cost and high energy consumption of the existing gas preservation logistics box, which cannot meet the requirements of long-distance transportation and long-term storage.
[0035] In this embodiment, two groups of handles 11 are symmetrically embedded on the upper end surface of the heat preservation cover 1. The symmetric embedding of the handles 11 allows the user to operate both hands simultaneously when opening or closing the heat preservation cover 1, which is more labor-saving and convenient, and facilitates the transportation of the box.
[0036] In this embodiment, a plurality of baffles 13 are uniformly fixed on the upper surface of the heat preservation cover 1 near the edge.
