This invention discloses a multifunctional controlled atmosphere constant temperature preservation storage device for grain silos, belonging to the field of grain storage technology. The key technical features include a grain silo body, with a ventilation mechanism fixedly connected inside. The ventilation mechanism is connected to an external air pipe. The ventilation mechanism includes a connecting pipe, the top of which is connected to several circular tubes, each with a tension spring fixedly connected inside.
