Technical Field

[0001] This utility model relates to the field of ground cage technology for grain warehouses, specifically to a ground cage ventilation structure for grain warehouses. Background Technology

[0002] A grain storage cage is a facility used for grain storage. It is generally installed on the ground of a grain warehouse. Its importance is particularly prominent in areas with high humidity and complex climate conditions. The main function of the cage is to provide ventilation, ensure that air can circulate effectively during the grain storage process, maintain air circulation inside the warehouse, reduce moisture accumulation, and thus prevent the grain from becoming moldy, spoiled, or rotten, thereby improving the storage quality of the grain.

[0003] However, the existing granary structure has poor ventilation, especially when the grain is piled up tightly, the ventilation holes of the granary are easily blocked, thus affecting air circulation. Once the ventilation holes are blocked, the humidity and temperature inside the granary are difficult to balance, which in turn affects the quality of the grain. Utility Model Content

[0036] Example

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment provides a ground cage ventilation structure for grain storage, including ventilation ducts 10, ventilation components 11, and fixing components 12. Multiple ventilation ducts 10 are provided, and the multiple ventilation ducts 10 are spaced apart on a preset ground surface of the grain storage. A connecting section 101 is provided between two adjacent ventilation ducts 10. The ventilation ducts 10 are provided with multi-segment air supply sections 102, and multiple ventilation holes 1021 are provided on the air supply sections 102. At least one regulating valve 104 is provided on the ventilation ducts 10. A ventilation duct 10 is connected to an air supply component 14, which can be a fan. The connecting section 101 makes each ventilation duct 10 form a loop, ensuring that the air volume is delivered along each ventilation duct 10 and discharged from the ventilation hole 1021, ensuring air circulation in the grain silo. The regulating valve 104 is used to regulate the air volume. The regulating valve 104 can be a pneumatic air volume regulating butterfly valve. It can be wirelessly connected to the electromagnetic switch of the regulating valve 104 through an external terminal (such as a mobile phone or computer) to open or close the regulating valve. This allows for flexible control of the ventilation effect according to changes in temperature and humidity in the grain silo, ensuring the quality of grain storage.

[0038] Multiple fasteners 12 are provided. The bottom surface of the ventilation duct 10 is provided with a side skirt structure 103. The fasteners 12 are located between the side skirt structure 103 and the preset ground. The ventilation duct 10 is fixedly installed on the preset ground by the fasteners 12 to ensure that the ventilation duct 10 is stable and not easy to move.

[0039] The ventilation assembly 11 includes a guide rod 111 disposed within the air supply section 102, a sliding plate 112 sleeved on the guide rod 111, and a power unit (not shown in the figure) that drives the guide rod 111 to move the sliding plate 112. The guide rod 111 is provided with a threaded section that mates with the threaded hole of the sliding plate 112. The sliding plate 112 is provided with a brush strip 1121 for sliding and cleaning the ventilation hole 1021. The power unit drives the guide rod 111 to rotate, and through the threaded engagement, drives the sliding plate 112 to move linearly along the guide rod 111. The brush strip 1121 moves accordingly to clean the ventilation hole 1021. The brush strip 1121 can extend into or penetrate the ventilation hole 1021, thereby effectively unblocking the ventilation hole 1021, preventing the accumulation of grain or impurities from clogging the ventilation hole 1021, and improving the ventilation effect of the cage structure.

[0040] Furthermore, multiple slide plates 112 are provided, and multiple slide plates 112 are spaced apart and fitted onto the guide rod 111. The ventilation holes 1021 are strip-shaped holes. Multiple slide plates 112 can be arranged at intervals along the length of the air supply section 102. Brush strips 1121 can cover the periphery of the slide plates 112, or multiple sets of brush strips 1121 corresponding to the ventilation holes 1021 can be provided. For example, each ventilation hole 1021 corresponds to a set of brush strips 1121. The brush strips 1121 extend into the ventilation hole 1021 or penetrate the ventilation hole 1021. When the power unit drives the guide rod 111 to rotate, each slide plate 112 moves synchronously, and the brush strips 1121 clean each ventilation hole 1021 in sequence, thereby improving cleaning efficiency, ensuring that multiple ventilation holes 1021 remain unobstructed, and further optimizing the ventilation effect.

[0041] like Figure 3 As shown, in this embodiment, a temperature and humidity sensor 1022 is installed inside the air supply section 102, and the temperature and humidity sensor 1022 is electrically connected to the power unit. The temperature and humidity sensor 1022 monitors the temperature and humidity changes inside the air supply section 102 in real time. When the ventilation hole 1021 of the air supply section 102 is blocked, the temperature and humidity sensor 1022 can sense the temperature and humidity changes, thereby triggering the power unit to start, driving the slide plate 112 to move and clean the ventilation hole 1021, restoring the ventilation effect and realizing automated management.

[0042] like Figure 4 and Figure 5 As shown, this embodiment also includes a positioning part 13 for interlocking with the fixing member 12. The positioning part 13 includes a housing 131 with an interlocking hole disposed on a preset ground, a spring 132 disposed inside the housing 131, and a spring head 133 connected to the spring 132 and sliding along the interlocking hole.

[0043] Specifically, the positioning part 13 is embedded in the pre-set ground and exposes a plug-in hole to engage with the fixing part 12. When the fixing part 12 is inserted into the plug-in hole, the spring 132 is compressed; after the fixing part 12 is removed, the spring 132 returns to its original shape, and the spring head 133 pops out, providing an automatic dustproof effect, thereby preventing grain or impurities from falling into the plug-in hole of the positioning part 13, facilitating subsequent installation and maintenance. The fixing part 12 can be a pin, steel nail, or bolt. For example, if the fixing part 12 is a bolt, the plug-in hole has an internal thread that matches the bolt thread, ensuring that the bolt is firmly inserted and not easily loosened. During disassembly, simply rotate the bolt in the opposite direction, and the spring force of the spring 132 will reset the spring head 133, improving maintenance efficiency.

[0044] like Figure 1 and Figure 2As shown, in this embodiment, the top surface of the air supply section 102 is an arc-shaped surface. Multiple ventilation holes 1021 are distributed along the arc-shaped surface. The arc design increases the ventilation area, makes the air flow more uniform, and can to some extent prevent grain from accumulating on the arc-shaped surface, thereby improving the ventilation effect.

[0045] like Figure 1 As shown, in this embodiment, the ventilation duct 10 is a closed-loop annular structure or a polygonal structure, and multiple annular structures or polygonal structures are set at equal intervals to form a uniformly distributed ventilation system, ensuring that all areas of the grain warehouse can be ventilated, preventing local heat accumulation or excessive humidity, which could lead to grain mold or pest infestation, and effectively improving the grain storage effect of the grain warehouse.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
