[0030] The following further describes the present utility model with specific embodiments, see Figure 1 —3:

[0031] A multi-functional ventilation opening for a granary, comprising a box body 1 with an opening at the front end and a sealing door 2 for sealing the front end of the box body 1. A ventilation duct 3 is arranged inside the box body 1, and a sealing cover 4 is provided for sealing the front end of the ventilation duct 3. The rear end of the ventilation duct 3 extends out of the box body 1 and communicates with the inside of the granary. A ventilation duct 5 is arranged on the box body 1. One end of the ventilation duct 5 communicates with the ventilation duct 3, and the other end extends out of the box body 1 and communicates with the inside of the granary. An air extraction device is arranged inside the ventilation duct 3. A thin film 14 for sealing the box body 1 is detachably connected to the opening at the front end of the box body 1, and the thin film 14 is located behind the sealing door 2. When the granary needs ventilation, the sealing door 2 and the sealing cover 4 are opened, the thin film 14 is removed, and the air extraction device drives the air flow inside and outside the granary. When the granary needs internal circulation, the sealing door 2 and the sealing cover 4 are closed, the thin film 14 is installed, and the air extraction device drives the air inside the granary to circulate between the granary, the ventilation duct 3 and the ventilation duct 5.

[0032] The working principle of the present utility model is as Figures 1-3 shown. When the granary needs to be sealed, the sealing cover 4 is closed to seal the ventilation duct 3, and the sealing door 2 is closed to seal the box body 1. When the granary needs ventilation, the sealing door 2 and the sealing cover 4 are opened, the thin film 14 is removed, and the air inside and outside the granary is driven to exchange and flow through the air extraction device. When the granary is fumigated, the sealing cover 4 is closed, the thin film 14 is installed, the sealing door 2 is closed, and the air extraction device is turned on. After the air inside the granary is driven by the air extraction device to enter from the rear end of the ventilation duct 3, it flows out from the ventilation duct 5 and re-enters the granary, or the air inside the granary enters from the ventilation duct 5 and then flows out from the rear end of the ventilation duct 3 and re-enters the granary, forming a cycle, so that the air inside the granary is circulated and the fumigation effect is good.

[0033] The present utility model can not only be used for ventilating the granary and sealing the granary, but also for circulating the air inside the granary during fumigation, with various functions. At the same time, by setting the thin film 14, air leakage of the box body can be effectively prevented during fumigation, so as not to affect the fumigation effect.

[0035] The connection structure between the ventilation duct two and the inside of the granary: The part of the ventilation duct 5 extending out of the box body 1 is embedded in the wall body. A ventilation duct 3 is arranged on the wall body, with one end extending out of the wall body and communicating with the inside of the granary. The other end of the ventilation duct 3 communicates with the ventilation duct 5, effectively avoiding the pipeline occupying the space inside the granary, thereby reducing the grain storage space. One end of the ventilation duct 3 extending out of the wall body is arranged at the top or bottom of the granary.

[0036] In order to be able to start the circulation only when it is necessary to circulate the air inside the loop-type granary, a valve for blocking and opening the second ventilation duct 5 is provided on the second ventilation duct 5, and the valve is arranged inside the box body 1. When the valve is closed, the air inside the granary cannot form a circulation through the second ventilation duct 5.

[0037] In order to facilitate the control of the opening and closing of the valve, the valve is a solenoid valve or an electric valve.

[0038] Installation structure of the film 14: As Figures 1-3 shown, an installation frame 6 is provided inside the box body 1, and the film 14 is installed on the installation frame 6. The structure is simple and it is convenient to disassemble and assemble the film 14.
