[0053] During the specific implementation of this embodiment, the opening and closing of the insulation cover assembly 4 can be completed by only one person operating the handle 5, which reduces the labor intensity of the custodian during daily grain checking; and through the design of the rubber ring sleeve 2 and the insulation cover assembly 4, the grain inlet of the underground granary can be effectively insulated and sealed.

[0054] In the above embodiment, the structure of the mounting member 3 has the following two solutions:

[0055] In the first solution, the mounting member 3 is composed of four pressing hand wheels. By operating the four pressing hand wheels, the thermal insulation cover assembly 4 can be flipped and locked. The pressing hand wheels are an existing commonly used connection and mounting structure, and this solution will not be described in detail.

[0056] In the second solution, the mounting member 3 is composed of a hinge and a lock. By operating the hinge and the lock, the thermal insulation cover assembly 4 can be flipped and locked. The hinge and the lock are the existing commonly used connection and mounting structures, and this solution will not elaborate on them.
