[0025] Reference Figure 1 and Figure 2According to the present invention, a grain warehouse ventilation system includes a warehouse body 100 and at least one set of ventilation components. The ventilation components include an air distribution box 210, a main air duct 220 and a branch air cage 230. The main air duct 220 is arranged horizontally and connected to the air distribution box 210. Multiple branch air cages 230 are longitudinally connected to the main air duct 220 and are distributed at equal intervals. The end of the main air duct 220 near the corner of the warehouse body 100 is connected to a first air duct 240 facing the corner of the warehouse body 100. The end of the branch air cage 230 near the side wall of the warehouse body 100 is connected to a second air duct 250 facing the corner of the warehouse body 100.

[0026] It is understood that the grain storage ventilation system provided in this embodiment of the present invention is arranged horizontally through the main air duct 220 and connected to the air distribution box 210, and multiple branch air cages 230 are distributed longitudinally and equidistantly along the main air duct 220, thereby achieving uniform ventilation in the internal area of ​​the storage 100. At the same time, a first air duct 240 facing the corresponding corner is provided at the end of the main air duct 220 near the corner, and a second air duct 250 facing the corresponding corner is provided at the end of the branch air cage 230 near the side wall, thereby ventilating the four corners of the storage 100, effectively covering the traditional ventilation dead corners, enhancing the airflow circulation capacity in the entire storage room, significantly improving the uniformity of airflow distribution and ventilation efficiency, effectively preventing problems such as grain heating and mold caused by local temperature and humidity accumulation, and improving the safety and stability of grain storage.

[0027] It should be noted that in this embodiment of the present invention, two first air ducts 240 and two second air ducts 250 are provided, each corresponding to one of the four corners of the silo 100. The air outlets of the first air ducts 240 and the second air ducts 250 are respectively facing the corresponding corners to achieve ventilation of the corners. For example, when there is only one set of ventilation components, one first air duct 240 is provided at each end of the main air duct 220, each corresponding to the nearest corner. At the same time, one second air duct 250 is provided at each of the two branch air cages 230 closest to the opposite side walls of the silo 100, each corresponding to the nearest corner. When there are two or more sets of ventilation components, one first air duct 240 is provided at each of the two main air ducts 220 closest to the opposite side walls of the silo 100, each corresponding to the nearest corner. At the same time, one second air duct 250 is provided at each of the two branch air cages 230 closest to the opposite side walls of the silo 100, each corresponding to the nearest corner.

[0028] Furthermore, refer to Figure 1 and Figure 2According to some embodiments of this utility model, the end of the air support cage 230 is laterally connected to the air branch pipe 260, which can further expand the ventilation path and enable the airflow to diffuse laterally on the basis of the air support cage 230, thereby improving the breadth and depth of airflow in the warehouse. This design helps to improve ventilation dead zones, enhance the response speed and uniformity of the overall ventilation system, and facilitates flexible adjustment according to the actual warehouse layout, improving the adaptability and practicality of the system.

[0029] Furthermore, according to some embodiments of this utility model, two adjacent bronchial pipes 260 may or may not be connected. It is understood that the selective connection or non-connection between two adjacent bronchial pipes 260 provides multiple ventilation path configurations, which can be dynamically adjusted according to the warehouse structure, grain type, and environmental conditions. This design not only enhances the system's flexibility but also helps optimize airflow organization, avoiding uneven ventilation caused by excessively high or low local wind pressure, thereby further improving ventilation efficiency and uniformity.

[0030] Furthermore, refer to Figure 2 According to some embodiments of this utility model, the surface of the air support cage 230 is uniformly provided with a plurality of first ventilation holes 231, the surface of the second air intake pipe 250 is uniformly provided with a plurality of second ventilation holes 251, and the surface of the branch pipe 260 is uniformly provided with a plurality of third ventilation holes 261. This allows airflow to be uniformly released through multiple ventilation holes, forming a multi-point air supply mode, significantly improving the ventilation coverage and the uniformity of airflow distribution. This structure helps reduce the disturbance caused by excessively high local wind speeds, while ensuring that all areas within the storage area receive stable and continuous ventilation support, which is beneficial for maintaining a good grain storage environment.

[0031] Similarly, according to some embodiments of this utility model, the surface of the first air duct 240 is provided with multiple fourth ventilation holes (not shown in the figure), which enables it to guide airflow to the corner while dispersing and releasing airflow to the surrounding area, avoiding localized excessive dryness or high humidity caused by "point-source air supply". This design further improves the ventilation quality in the corner area and enhances the stability and consistency of the entire warehouse's internal environment.

[0032] Preferably, according to some embodiments of this utility model, there are three sets of ventilation components, which are distributed laterally at equal intervals, thereby achieving uniform air distribution over a larger area and effectively avoiding the problem of insufficient coverage caused by a single set of ventilation components. The coordinated operation of multiple sets of ventilation components not only improves the overall ventilation capacity but also meets the needs of large-space warehouses or multi-grain storage, exhibiting stronger applicability and operational stability.

[0033] Preferably, according to some embodiments of this utility model, the distance between two adjacent ventilation cages 230 is 3.5m. It is understood that, based on the inventors' experiments, this distance ensures adequate ventilation coverage density without wasting equipment resources in practical applications. This design, while ensuring ventilation effectiveness, also considers construction costs and ease of maintenance, making it suitable for the mass construction and widespread application of standardized grain silos.

[0034] It should be noted that in some embodiments, the spacing between two adjacent support cages 230 can be designed according to actual needs. For example, it can be 3m, 4m, 5m or other spacings, which will not be elaborated here.

[0035] Furthermore, according to some embodiments of this utility model, a blower is installed inside the air distribution box 210 to provide active air supply power for the entire ventilation system, solving the problems of strong dependence on and low efficiency of natural ventilation. The blower can quickly establish a stable airflow circulation, significantly improving the ventilation start-up speed and system response capability, and is especially suitable for high temperature and humidity or highly sealed warehouse environments, helping to timely regulate the temperature and humidity inside the warehouse and ensure the safety of grain storage.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
