[0025] In operation, first, nut one and nut two are released by a certain distance. If nut one or nut two is difficult to loosen, a certain amount of lubricant can be sprayed. Then, the first rotating plate 21 is counterclockwise rotated around the first screw column 211, so that the first rotating rod 214 is close to the stop block three 212. Then, the second rotating plate 22 is clockwise rotated around the second screw column 221, so that the second rotating rod 224 is close to the stop block four 222. In this way, the first rotating plate 21 and the second rotating plate 22 are in an open state. Then, the pressure relief device at the rear side of the silo box 1 is started. Then, the edge at the rear side of the warehouse door 3 is pried with a crowbar to lift one side of the warehouse door 3, so that the warehouse door 3 is rotated around the rotating shaft. In this way, the warehouse door 3 is opened. The positions of the first sealing ring 301 and the second sealing ring 302 need to be observed. If the first sealing ring 301 and the second sealing ring 302 are stuck to the surface of the silo box 1, they need to be manually placed back in position. Then, the items are placed in the containing cavity 13. After the items are placed, the warehouse door 3 is closed again, so that the rear side of the warehouse door 3 is attached to the front side of the silo box 1. Then, the first rotating plate 21 is clockwise rotated, and the second rotating plate 22 is counterclockwise rotated, so that the first rotating plate 21 is attached to the stop block one 34, and the second rotating plate 22 is attached to the stop block two 33. The warehouse door 3 needs to be pressed tightly against the silo box 1. Finally, the second rotating plate 22 and the first rotating plate 21 are respectively combined with the front side of the warehouse door 3, the first sealing ring 301 and the second sealing ring 302 are also squeezed to seal the opening 12, and finally, nut one and nut two are tightened to apply a pressing force to the warehouse door 3.
[0026] Through the above steps, the rotation of the bin door 3 realizes the opening or closing of the silo box 1, and the first rotating plate 21 and the second rotating plate 22 rotating in front of the silo box 1 help to reduce the space of the safety assembly one, prevent the safety assembly two from protruding too far to the front side, increase the land use efficiency, and the blocking of the first rotating plate 21 and the second rotating plate 22 to the front side of the bin door 3 prevents the bin door 3 from being accidentally pushed open when closing, and the coaxial arrangement of the first sealing ring 301 and the second sealing ring 302 of the safety assembly two realizes double insurance, prevents water from entering when one of them is damaged, and solves the problem that the device in the prior art has outwardly protruding top columns, rotating sleeves and other components, and at the same time, these components are vertically directed to the outside, thus occupying a large amount of outside space, and the limited space inside cannot be fully utilized.
