[0032] In this embodiment, the conveying assembly includes a connecting pipe 3, a steel plate 4, an air pipe 9 and an air pump 8. Two connecting pipes 3 are welded on the steel pipe 2. One end of the two connecting pipes 3 is rotatably connected to a steel plate 4. Both steel plates 4 are provided with a cavity 5 for the purpose of conveying carbon dioxide into the granary 1.
