Figure 1 、 Figure 2 and Figure 3 , the ventilation pipe structure at the bottom of the granary is assembled at the bottom of the side wall of the granary, and a ventilation hole is opened at the bottom of the granary (this is the existing technology, so it is not shown in the figure), the ventilation pipe main body 1, the filter screen 2, the external pipe 3 and the cover plate 4, the ventilation pipe main body 1 is snap-connected to the bottom of the granary, the filter screen 2 is connected to the ventilation pipe main body 1, the axis of the filter screen 2 is collinear with the axis of the ventilation pipe main body 1, the filter screen 2 is located at the end of the ventilation pipe main body 1 outside the granary, the external pipe 3 is coaxially connected to the ventilation pipe main body 1, a quick-connect assembly 5 is provided between the external pipe 3 and the ventilation pipe main body 1, an insect-proof assembly 6 is provided inside the external pipe 3, a fixing ring plate 41 is connected to the cover plate 4, the fixing ring plate 41 is arranged along the circumference of the cover plate 4, an extrusion ring 42 is affixed to the fixing ring plate 41, and the extrusion ring 42 is arranged on the inner wall of the fixing ring plate 41, an insulation plate 43 is affixed to the cover plate 4, and the insulation plate 43 is located on the plate surface of the cover plate 4 facing the external pipe 3.

[0022] During installation, the ventilation pipe body 1 is clamped into the ventilation hole at the bottom of the granary, and then the external tube 3 and the ventilation pipe body 1 are connected through the quick-connect assembly 5, and finally the cover plate 4 is directly covered on the end of the external tube 3 through the fixed ring plate 41 and the extrusion ring 42; when in use, the filter 2 is used to filter the dust in the air hole, and the insect-proof assembly 6 is used to prevent rats and ants from entering the granary through the external tube 3 to destroy the filter 2, and the external tube 3 can be quickly disassembled and assembled through the quick-disassembly assembly. When maintenance is required, only the external tube 3 needs to be disassembled to clean the inside of the external tube 3 and the filter 2.

[0023] The ventilation pipe body 1 is provided with protrusions 11, and several protrusions 11 are evenly arranged along the circumference of the ventilation pipe. When installing the ventilation pipe body 1, the ventilation pipe body 1 is clamped into the ventilation hole at the bottom of the granary.

The second fixing ring 52 is provided with a clamping groove for the clamping block 57 to be clamped.

[0026] When the first fixing ring 51 and the second fixing ring 52 are installed separately, first pull the clamping block 57 outward and rotate the clamping block 57 to one side to prevent the clamping block 57 from affecting the installation of the first fixing ring 51 and the second fixing ring 52. Then, the first fixing ring 51 and the second fixing ring 52 are assembled with each other, and then the clamping block 57 is pulled outward and reset so that the clamping block 57 is aligned with the slot on the second fixing ring 52. The clamping block 57 is released, and the slide plate 55 is pushed by the spring 56 to drive the clamping block 57 to be clamped into the slot through the pull rod 54 to connect the first fixing ring 51 and the second fixing ring 52.

[0027] A positioning post 511 is connected to the first fixing ring 51, and the positioning post 511 is arranged in a direction perpendicular to the first fixing ring 51.

[0028] The insect-proof component 6 includes a first fixed tube 61 and a second fixed tube 62, which are both connected to the external tube 3. The first fixed tube 61 and the second fixed tube 62 are respectively located at opposite ends of the external tube 3. The first fixed tube 61, the second fixed tube 62 and the external tube 3 are coaxially arranged. The first fixed tube 61 and the second fixed tube 62 are both hollow truncated cones. The conical surfaces of the first fixed tube 61 and the second fixed tube 62 are arranged opposite to each other. Insect repellent is placed in the external tube 3 and is located between the first fixed tube 61 and the second fixed tube 62. With this arrangement, after rats and ants enter the external tube 3 from the first fixed tube 61, it is difficult for them to climb to the pipe mouth of the second fixed tube 62. In addition, there is insect repellent between the first fixed tube 61 and the second fixed tube 62, which can kill rats and ants, thereby achieving an insect-proof effect.
