[0027] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0028] Example

[0029] See Figures 1-6 A new type of grain storage structure includes:

[0030] The main body of the grain silo includes a silo wall 1 and a silo roof 2;

[0031] The exhaust duct 3 has an air inlet located inside the main body of the grain silo and an air outlet extending outside the main body of the grain silo. The section of the exhaust duct 3 located outside the main body of the grain silo is arranged in a vertical direction.

[0032] Longitudinal ventilation pipe 4, there are multiple longitudinal ventilation pipes 4, one end of the longitudinal ventilation pipe 4 extends into the inner cavity of the main body of the grain silo or passes through the inner cavity of the main body of the grain silo and the bottom plate and exits from the bottom plate of the main body of the grain silo to below the bottom plate, and the other end is connected to the air inlet of the exhaust pipe 3 through the air collection box 19; each of the longitudinal ventilation pipes 4 has multiple air inlet holes 5 along the length of the pipe wall;

[0033] A horizontal ventilation pipe 6 is located in the grain pile inside the main body of the grain warehouse, and the two ends of the horizontal ventilation pipe 6 extend from the warehouse wall 1 to the outside of the main body of the grain warehouse. Multiple ventilation holes 7 are opened on the pipe wall of the horizontal ventilation pipe 6.

[0034] Discharge port 8 is located at the bottom of the main body of the grain silo, and an opening and closing valve is provided on the discharge port 8.

[0035] In this embodiment, by arranging horizontal ventilation pipes 6 and multiple vertical ventilation pipes 4 inside the main body of the grain silo, the horizontal ventilation pipes 6 introduce air into the grain silo and then disperse it into the grain pile inside the main body of the grain silo through ventilation holes 7, thus solving the drying problem during grain storage by utilizing natural ventilation. During this process, the vertical ventilation pipes 4 have multiple air inlets 5 along the length of the pipe wall and are concentrated in the air collection box and exhaust pipe. Furthermore, by setting the exhaust pipe 3 outside the main body of the grain silo vertically, the airflow through the exhaust pipe generates lift, further increasing the ventilation volume of the horizontal ventilation pipes 6, so that the horizontal and vertical ventilation inside the main body of the grain silo is good, avoiding the problem of poor ventilation inside the main body of the grain silo in traditional structures.

[0036] In this embodiment, the transverse ventilation pipes 6 on the same horizontal plane can be densely distributed according to the local prevailing wind direction and slightly sparsely distributed according to other wind directions to ensure good transverse ventilation in the warehouse.

[0037] In this embodiment, an extension section is provided on the exhaust duct 3 outside the main body of the grain warehouse. The total height of the exhaust duct 3 outside the main body of the grain warehouse can be adjusted by the relative elongation of the extension section, thereby adjusting the airflow lift inside the exhaust duct. This not only allows for adjustment of the air volume but also adapts to various types of grain storage.

[0038] It should be noted that the telescopic section can be a sleeve 9 arranged axially along the exhaust duct 3, or a corrugated pipe section 10 arranged on the exhaust duct 3; and other cylindrical structures that can adjust their own elongation are also applicable to this utility model. In this embodiment, the exhaust duct 3 is also provided with an adjusting limit mechanism 11 for adjusting and fixing the relative elongation of the sleeve 9 or the corrugated pipe section 10. The specific structure of the adjusting limit mechanism 11 can be in various forms. For example, when the sleeve 9 is used as the telescopic section, the sleeve 9 and the exhaust duct 3 can be connected by threads, and the relative elongation can be adjusted by rotating the sleeve 9. In addition, the relative elongation can also be adjusted by setting mounting rings on the sleeve 9 and the exhaust duct respectively, and then setting a telescopic mechanism between the mounting rings. Similarly, other adjusting limit mechanisms 11 that can realize the relative elongation of the sleeve 9 or the corrugated pipe section 10 are also applicable to this utility model.

[0039] In this embodiment, a waterproof cap 12 is provided at the air outlet end of the exhaust duct 3 to prevent rainwater from entering the main body of the grain silo through the outlet end of the exhaust duct 3.

[0040] The silo wall 1 has a sieve-like structure. For example, in this embodiment, the silo wall 1 of the main body of the grain silo is made of metal sieve material, which can ensure good natural ventilation all around.

[0041] In this embodiment, the edge of the top 2 of the grain silo body extends outward from the outer perimeter of the silo wall 1, and the edge of the top 2 is provided with a circumferential slide 13. A slide-type rain curtain 14 that cooperates with the circumferential slide 13 is installed on the slide 13. The slide-type rain curtain 14 hangs down from the edge of the top 2 to a position close to the bottom of the grain silo body to ensure that the grain inside the grain silo body is not wetted by rain.

[0042] In this embodiment, the bottom of the grain silo body is provided with two opposing transverse guide rails 15, which are distributed on both sides of the discharge port 8. The opening and closing valve of the discharge port 8 includes a movable guide trough 16, which is installed on the two transverse guide rails 15. An insert plate 17 is provided at the outlet end of the movable guide trough 16. The transverse guide rails 15 and the movable guide trough 16 cooperate to form a drawer-type pull-out structure, and the discharge port 8 can be opened and closed by pulling out and inserting the insert plate 17 to realize grain storage and unloading. In addition, when it is necessary to clean or repair the grain silo body, by fully pulling out the movable guide trough 16 and opening the insert plate 17, cleaning or repair personnel can enter the grain silo body through the bottom discharge port 8 to clean or repair the grain silo body.

[0043] In this embodiment, the bottom of the main body of the grain silo is also provided with support columns, so that the main body of the grain silo is raised to a certain height from the ground, thus avoiding the problem of rodent damage.

[0044] In this embodiment, both the air inlet 5 and the ventilation hole 7 can be slits 2 mm wide and 100 mm long to avoid the problem of being easily blocked by grain when using round holes as air inlets 5 or ventilation holes 7. All components of the new grain silo structure can be manufactured in a miniaturized and standardized manner, ensuring that all components can be disassembled, assembled, and moved at any time and place, meeting the needs of grain farmers and grain processing enterprises.
