Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-4This utility model provides an embodiment of an intelligent ventilation device for grain silos, comprising a grain silo body 1, a blower 2 fixedly installed on the outside of the grain silo body 1, a ventilation pipe 3 fixedly connected to the output end of the blower 2, two sets of ventilation pipes 3, a connecting pipe 4 fixedly connected between the two sets of ventilation pipes 3, an air supply pipe 5 fixedly connected to the ventilation pipe 3, a ventilation opening 6 fixedly connected through the air supply pipe 5, a partition plate 23 fixedly connected inside the grain silo body 1, the air supply pipe 5 passing through the partition plate 23, and a temperature and humidity recorder 22 fixedly installed on the outside of the grain silo body 1. The temperature and humidity recorder 22 is model TM-TH-4G. The operator can monitor the internal temperature and humidity of the grain silo through the temperature and humidity recorder 22. Regarding humidity, when the temperature and humidity inside the grain silo are relatively stable and do not require significant adjustment, the electric push rod 10 is activated. The electric push rod 10 pushes the rack 11 to move, and the rack 11 drives the baffle 13 to rotate within the exhaust vent 7 via the driven gear 12. This adjusts the position of the baffle 13 within the exhaust vent 7, preventing it from blocking the exhaust vent 7 and thus opening the exhaust vent 7 for natural ventilation. At this time, it is not necessary to start the blower 2 and exhaust fan 8. Natural ventilation is used to regulate the temperature and humidity inside the grain silo, eliminating the need to continuously run the blower 2 and exhaust fan 8. This reduces maintenance costs, alleviates the burden of manual management, and reduces energy consumption, which is beneficial for energy conservation and emission reduction, and improves the environmental friendliness of the device.

[0029] In addition, an exhaust vent 7 is fixedly connected through the grain silo body 1, an exhaust fan 8 is fixedly installed inside the exhaust vent 7, and a filter screen 9 is fixedly connected inside the exhaust vent 7. An electric push rod 10 is fixedly connected to the inner wall of the grain silo body 1, and a rack 11 is fixedly connected to the output end of the electric push rod 10. A driven gear 12 is meshed on the rack 11, and a baffle 13 is fixedly connected to the driven gear 12. A sliding groove 14 is opened on the rack 11. A fixing block 15 is fixedly connected to the inner wall of the grain silo body 1, with one end of the fixing block 15 located in the sliding groove 14. The fixing block 15 and the sliding groove 14 are slidably connected. When the grain silo... When the temperature and humidity inside are high and need adjustment, keep the exhaust vent 7 open and start the blower 2. The blower 2 sends air into the air supply pipe 5 through the ventilation pipe 3 and connecting pipe 4. The air is sprayed out from the vent 6 on the air supply pipe 5. At the same time, start the exhaust fan 8 to quickly ventilate the grain silo, thereby regulating the temperature and humidity inside the grain silo. The filter screen 9 can filter the grain husks inside the grain silo into the grain silo body 1. A drive motor 16 is fixedly installed inside the grain silo body 1. The output end of the drive motor 16 is fixedly connected to a transmission rod 17. One end of the transmission rod 17 is fixedly connected to... There is a driving bevel gear 18, which is meshed with a driven bevel gear 19. A stirring rod 20 is fixedly connected to the driven bevel gear 19, and a stirring blade 21 is fixedly connected to the stirring rod 20. The ventilation pipe 3 is located below the partition plate 23. There are four sets of air supply pipes 5 evenly distributed inside the grain silo body 1. There are multiple sets of ventilation openings 6 evenly distributed on the air supply pipes 5. There are two sets of exhaust openings 7 symmetrically distributed on both sides of the grain silo body 1. There are two sets of exhaust fans 8, filter screens 9, electric push rods 10, and baffles 13. The rack 11 and driven gear 12 are located above the exhaust openings 7. The drive motor 16 is located above the air supply pipe 5. The stirring rod 20 rotates inside the grain silo body 1. There are five sets of stirring blades 21 evenly distributed on the stirring rod 20. When the drive motor 16 is started, the drive motor 16 drives the active bevel gear 18 to rotate through the transmission rod 17. The active bevel gear 18 drives the stirring rod 20 to rotate through the driven bevel gear 19. The stirring rod 20 drives the stirring blades 21 to rotate. The rotation of the stirring blades 21 is used to turn the grain, so that the grain piled inside can also be effectively ventilated, avoiding mold due to poor ventilation. This is beneficial to the storage of grain in the grain silo and improves the practicality of the device.

[0030] Working Principle: When using this intelligent ventilation device for grain silos, the operator monitors the temperature and humidity inside the silo via the temperature and humidity recorder 22. When the temperature and humidity inside the silo are relatively stable and do not require significant adjustment, the electric push rod 10 is activated. The electric push rod 10 pushes the rack 11 to move, and the rack 11, through the driven gear 12, drives the baffle 13 to rotate within the exhaust vent 7, thereby adjusting the position of the baffle 13 within the exhaust vent 7 so that the baffle 13 no longer blocks the exhaust vent 7, thus opening the exhaust vent 7 for natural ventilation. At this time, it is not necessary to start the blower 2; natural ventilation is used to regulate the temperature and humidity inside the grain silo. When the temperature and humidity inside the grain silo are high and adjustments are needed, the exhaust vent 7 is kept open, and the blower 2 is started. The blower 2 sends air into the air supply pipe 5 through the ventilation pipe 3 and connecting pipe 4, and the air is ejected from the ventilation opening 6 on the air supply pipe 5. At the same time, the exhaust fan 8 is started, utilizing... The exhaust fan 8 provides rapid ventilation to the grain silo, regulating the temperature and humidity. The filter screen 9 filters grain husks within the silo body 1, preventing fine impurities like grain husks from entering the exhaust fan 8 and affecting its operation. Simultaneously, the drive motor 16 is activated, driving the active bevel gear 18 via the transmission rod 17. The active bevel gear 18, through the driven bevel gear 19, drives the stirring rod 20, which in turn drives the stirring blades 21. The rotation of the stirring blades 21 turns the grain, ensuring effective ventilation and preventing mold growth due to poor ventilation. When the outside weather is cloudy or rainy, the electric push rod 10 is activated, driving the driven gear 12 via the rack 11. This adjusts the position of the baffle 13 within the exhaust vent 7, blocking the vent and preventing external moisture from entering the grain silo and affecting grain storage.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
