[0017] Please refer to Figure 1 and Figure 2 The top of the main ventilation pipe 30 extends to the main ventilation opening 21, and the bottom end of the main ventilation pipe 30 passes through the bottom end of the warehouse body 20, and the bottom end of the main ventilation pipe 30 is connected to the fan 40. A feed support 50 is wound around the outer peripheral wall of the main ventilation pipe 30, and the feed support 50 has a multi-layer spiral structure. The outer peripheral wall of the main ventilation pipe 30 is provided with a secondary ventilation pipe 31 corresponding to the bottom surface of each layer of the feed support 50. The secondary ventilation pipe 31 is connected to the main ventilation pipe 30, and the secondary ventilation pipe 31 is connected to a plurality of exhaust pipes 32. An exhaust port 51 is opened at the position corresponding to the exhaust pipe 32 on each layer of the feed support 50. The exhaust pipe 32 extends to the exhaust port 51, and a filter is provided at the exhaust port 51.
[0018] In the above scheme, the main ventilation port 21 also serves as the grain inlet. The grain enters the feed support 50 inside the silo 20 from the main ventilation port 21. The grain slides down along the spiral structure by its own gravity, and the spiral structure is used to layer the grain. An exhaust port 51 is opened on each layer of the feed support 50, which cooperates with the exhaust pipe 32. At the same time, the exhaust pipe 32 is connected to the auxiliary ventilation pipe 31, and the auxiliary ventilation pipe 31 is connected to the main ventilation pipe 30. The fan 40 at the end of the main ventilation pipe 30 is started to ventilate and dry the grain, which has a good effect. The outer surface and interior of the entire grain pile can be well ventilated and dried to prevent the generation of mildew and insects, and effectively protect the grain.

When not in use, the main vent 21 and auxiliary vent 23 are covered with the main cover 22 and auxiliary cover 24, respectively, to protect the grain from rain and dew.
[0021] Specifically, a grain unloading port is provided at the bottom end of the silo body 20, and a grain unloading switch 25 is provided at the grain unloading port, so that the grain inside the silo body 20 can be conveniently taken out through the grain unloading port.
[0022] Specifically, the silo 20 is constructed of sheet iron, and the support 10 is constructed of several steel tubes. The silo 20 is positioned within the support 10. The silo 20 is constructed of sheet iron and placed on the steel tube support 10, providing storage for grain and protecting it from rain and moisture. In this embodiment, the support 10 has an inner cavity formed therein to facilitate placement of the silo 20, ensuring its secure placement.
