Description

Technical Field

[0001] This utility model relates to the technical field of rice storage facilities, and in particular to a rice storage ventilation and cooling device. Background Technology

[0002] A rice silo is a warehouse used to store grains such as rice. During the storage of rice in the silo, moisture in the atmosphere enters the silo through the inlet, outlet, inspection port, and weld seams. This moisture condenses into dampness when it encounters temperature changes, causing the inside of the silo to become damp. Therefore, workers use ventilation and cooling devices to ventilate and cool the inside of the rice silo to prevent the rice from spoiling due to temperature and humidity. Common ventilation and cooling devices for rice silos include single-tube fans.

[0003] In grain storage management, single-pipe fans can effectively regulate the temperature and ventilate the grain silo. However, insects and dust from the external environment may enter the silo through the fan ducts. Insects not only feed on the grain but also breed and lay eggs inside the silo, leading to insect infestation and contamination. Meanwhile, dust can clog the gaps between grains, affecting airflow within the silo. Furthermore, dust itself may carry microorganisms, increasing the risk of grain mold. To address this risk, staff install filters inside the fan ducts. While this effectively traps airborne dust and insects, preventing them from entering the rice storage area, the filters gradually accumulate dust and impurities over time. When these contaminants build up to a certain level, the filters become clogged, affecting ventilation and cooling efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a rice storage ventilation and cooling device. When the rice storage does not require cooling and ventilation, the connecting pipe can be sealed. When ventilation is required, the protective plate can be automatically pushed to ensure ventilation efficiency while preventing external dust and insects from entering the storage.

[0006] To achieve the above objectives, the first aspect of this utility model provides a rice storage ventilation and cooling device, comprising: a fan and a protective assembly, wherein the fan includes a housing, a drive assembly, and a ventilation assembly; the protective assembly includes a connecting pipe, two sets of limiting assemblies, a protective plate, and a sealing gasket, wherein the connecting pipe is connected to the output pipe of the housing, the two sets of limiting assemblies are symmetrically arranged at the other end of the connecting pipe; the protective plate is disposed inside the connecting pipe through the sealing gasket, and the protective plate is slidably connected to the two sets of limiting assemblies.

[0007] In addition, the rice warehouse ventilation and cooling device proposed above according to this utility model may also have the following additional technical features: Specifically, each set of limiting components includes a connecting plate, a limiting post, and a baffle. The connecting plate is disposed on the outer wall of the connecting pipe; the limiting post is disposed on the connecting plate; and the baffle is connected to the other end of the limiting post.

[0008] Specifically, magnetic rings are provided on the outer wall of the sealing gasket and the inner wall of the connecting pipe.

[0009] Compared with existing technologies, this invention has the following advantages: When ventilation is required, the airflow generated by the fan can automatically push the protective plate open; when the fan stops running, the protective plate can be returned to the inside of the connecting pipe through a limiting mechanism for sealing. This design ensures ventilation efficiency during fan operation while effectively preventing external dust and insects from entering the silo, thus avoiding problems such as grain infestation and contamination.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0014] The following describes an embodiment of the rice storage ventilation and cooling device of this utility model with reference to the accompanying drawings.

[0015] like Figures 1-3 As shown, the rice storage ventilation and cooling device of this utility model embodiment includes: a fan 1 and a protective component 2.

[0016] The fan 1 includes a housing 11, a drive assembly and a ventilation assembly, and the protective assembly 2 includes a connecting pipe 21, two sets of limiting assemblies 22, a protective plate 23 and a sealing gasket 24.

[0017] It should be noted that the drive assembly and ventilation assembly described in this embodiment include a drive component 12 and a fan blade 13. The drive component 12 is disposed on the outer wall of the housing 11, and the shaft of the fan 1 passes through the housing 11 and is connected to the fan blade 13, which is located inside the housing 11. The ventilation assembly includes a connecting pipe 14 and an output pipe (not shown in the figure) disposed on the outer wall of the housing 11.

[0018] Additionally, it should be noted that the driving component 12 described in this embodiment is a drive motor, and the housing of the driving component 12 is relatively fixed to the housing 11, and the rotating shaft of the driving component 12 can rotate freely inside the housing 11.

[0019] Specifically, when the staff turns on the drive unit 12 with the help of the external control device, the drive unit 12 will drive the fan blade 13 to rotate inside the housing 11, thereby drawing the air inside the rice bin into the housing 11 through the connecting pipe 14, and then delivering it to the outside of the housing 11 through the output pipe, thereby ventilating and cooling the inside of the rice bin.

[0020] The connecting pipe 21 is connected to the output pipe of the housing 11. Two sets of limiting components 22 are symmetrically arranged at the other end of the connecting pipe 21. The protective plate 23 is arranged inside the connecting pipe 21 through the sealing gasket 24, and the protective plate 23 is slidably connected to the two sets of limiting components 22.

[0021] The baffle 223, protective plate 23, and sealing gasket 24 are all made of lightweight carbon fiber materials, so as not to affect the displacement after being subjected to wind force.

[0022] Each set of limiting components 22 includes a connecting plate 221, a limiting post 222, and a baffle 223.

[0023] The connecting plate 221 is disposed on the outer wall of the connecting pipe 21, the limiting post 222 is disposed on the connecting plate 221, and the baffle 223 is connected to the other end of the limiting post 222.

[0024] Specifically, when the fan blade 13 draws air from inside the grain bin into the connecting pipe 21 through the output pipe of the casing 11, the airflow will blow the protective plate 23 upward along the direction defined by the limiting post 222, thereby allowing the airflow to be discharged smoothly, reducing the temperature inside the grain bin and ventilating it.

[0025] When the drive unit 12 stops working, the fan blade 13 stops rotating. At this time, the protective plate 23 loses the thrust brought by the airflow and falls down along the direction limited by the limit post 222. At this time, the sealing gasket 24 returns to the inside of the connecting pipe 21. Meanwhile, the protective plate 23 is above the connecting pipe 21, forming a seal on the connecting pipe 21, thereby preventing external dust and insects from entering the warehouse and causing problems such as insect infestation and contamination of the grain.

[0026] In one embodiment of this utility model, such as Figure 3 As shown, magnetic rings 3 are respectively provided on the outer wall of the sealing gasket 24 and the inner wall of the connecting pipe 21.

[0027] It should be noted that the two magnetic rings 3 described in this embodiment should be rubber magnets because they are lighter and have weaker adsorption capacity, thus ensuring that the displacement of the protective plate 23 will not be affected when the wind blows.

[0028] It is understandable that the magnetic rings 3 are respectively set on the outer wall of the sealing gasket 24 and the inner wall of the connecting pipe 21. When the sealing gasket 24 returns to the inside of the connecting pipe 21, the two magnetic rings 3 attract each other, thereby preventing the protective plate 23 from shifting due to slight force.

[0029] In summary, when ventilation is required, the airflow generated by the fan automatically pushes the protective plate open. When the fan stops running, the protective plate can be returned to the connecting pipe via a limiting mechanism for sealing. This design ensures efficient ventilation during fan operation while effectively preventing external dust and insects from entering the silo, thus avoiding problems such as insect infestation and contamination of the grain.
