[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] like Figures 1 to 7 As shown, this utility model provides a ground-level cage ventilation structure for grain storage, including a ventilator 1 and multiple modularly assembled cage bodies 2;

[0028] The air outlet of the ventilator 1 is connected to the air supply hood 3;

[0029] An outer panel 23 is installed at the air outlet end of the air supply hood 3 and at one end of the cage body 2. An inner panel 24 is provided at the other end of the cage body 2 to engage with the outer panel 23. The outer panel 23 contains a magnet that magnetically attracts the inner panel 24. The inner panel 24 is made of ferromagnetic material.

[0030] In terms of workflow, the ventilator 1 generates airflow, which is then introduced into the cage 2 via the air supply hood 3 through the magnetic snap-fit ​​between the outer splicing plate 23 and the inner splicing base 24 of the cage 2. During installation, the outer splicing plate 23 is simply aligned with the inner splicing base 24 to complete the splicing. Disassembly is performed in reverse. This solution solves the technical problems of complex installation and difficulty in flexibly adjusting according to the actual grain silo conditions of traditional ventilation structures. The beneficial effect is that it realizes the modularization of the ventilation structure. The number of cages 2 can be easily increased or decreased according to the actual size of the grain silo and ventilation requirements, which significantly improves the adaptability and expandability of the ventilation structure and greatly reduces the installation and maintenance costs. It is highly flexible in practical applications.

[0031] The upper part of the cage body 2 is provided with a set of upper bar holes 4, which are arc-shaped holes;

[0032] An adjusting frame 5 is slidably installed on the cage 2 via a sliding groove, and an adjusting arc plate 6 is installed on the adjusting frame 5 at the position corresponding to each upper bar hole 4;

[0033] The central angles of the upper hole 4 and the adjusting arc plate 6 are both 180°;

[0034] Two partitions 7 are installed inside the cage body 2. A ventilation filter cylinder 8 is provided inside the cage body 2 and is rotatably connected to the partitions 7. The ventilation filter cylinder 8 is a hollow cylindrical structure with open ends. The center of the upper slot 4 and the arc of the adjusting arc plate 6 are on the axis of the ventilation filter cylinder 8.

[0035] The upper air chamber is located inside the cage 2 and above the rotation axis of the ventilation filter 8. The upper air chamber is connected to the upper bar hole 4.

[0036] A set of internal filter holes 9 is provided on the ventilation filter cylinder 8 and at the position corresponding to each upper bar hole 4. A lower air chamber is provided inside the cage body 2 at the position corresponding to the two partitions 7 and the ventilation filter cylinder 8. A set of lower through holes 10 communicating with the lower air chamber is provided on both sides of the cage body 2. The diameter of the internal filter holes 9 and the lower through holes 10 is the same, and the axes of the internal filter holes 9 and the lower through holes 10 are perpendicular to the axis of the ventilation filter cylinder 8.

[0037] During operation, the operator slides the adjusting frame 5, which moves the adjusting arc plate 6, thereby changing the ventilation area, ventilation hole diameter, and ventilation direction of the upper slot 4. This solves the problem that the ventilation opening cannot be flexibly adjusted according to the type of grain stored and the ventilation requirements. It can accurately control the ventilation volume and ventilation angle of the upper air chamber, so that the ventilation system can adapt to the ventilation requirements under different grain storage conditions, effectively improve ventilation efficiency, create a more suitable air circulation environment for grain, and help preserve the quality and freshness of grain.

[0038] The cage 2 is equipped with a pneumatic assembly that drives the ventilation filter cartridge 8 to rotate;

[0039] The wind-driven assembly includes an air collection hood 19 installed on the inner wall of the cage 2. A power shaft 20 is rotatably installed on the inner wall of the air collection hood 19. A set of wind-driven blades 21 arranged in a circular array are installed on the power shaft 20. An active bevel tooth is fixedly installed at one end of the power shaft 20. A driven bevel tooth ring 22 that meshes with the active bevel tooth is fixedly installed on the inner wall of the ventilation filter 8.

[0040] During ventilation, airflow enters the cage 2 and, through the rotation of the ventilation filter cylinder 8, changes the connection between the inner filter hole 9 and the lower through hole 10, thereby controlling the ventilation volume of the lower air chamber. At the same time, the upper air chamber is ventilated through the upper strip hole 4, forming a three-dimensional ventilation mode between the upper and lower air chambers. This solution solves the problems of uneven ventilation and inability to fully cover the grain storage space in traditional ventilation structures. The effect is to enable air to flow three-dimensionally and evenly in the grain storage, comprehensively improve ventilation efficiency, effectively prevent grain from deteriorating due to poor local ventilation, and create good environmental conditions for long-term stable storage of grain.

[0041] Furthermore, the rotation of the ventilation filter cylinder 8 can effectively reduce the clogging rate of grain on the inner filter holes 9, thereby maintaining the smooth ventilation of the inner filter holes 9.

[0042] When the ventilation airflow enters the cage 2, the air collecting hood 19 collects the airflow and drives the wind turbine blades 21 to rotate. The wind turbine blades 21 drive the power shaft 20 to rotate, which in turn causes the active bevel gear to rotate. Through meshing with the driven bevel gear ring 22, the ventilation filter cartridge 8 is driven to rotate. This solves the problem that the ventilation filter cartridge 8 requires an additional power source to drive it, resulting in high energy consumption and complex structure. It realizes the use of the ventilation airflow itself to drive the ventilation filter cartridge 8 to rotate without external power, saving energy while ensuring the stable operation of the ventilation system and improving the intelligence and energy efficiency of the ventilation structure.

[0043] A rotating frame 11 is rotatably installed inside the ventilation filter cartridge 8, and an air guide arc plate 12 is fixedly installed on the rotating frame 11;

[0044] The air guide arc plate 12 has an arc-shaped curved surface with a central angle of 180°, and the center of the arc of the air guide arc plate 12 is on the axis of the ventilation filter cartridge 8;

[0045] A drive shaft 13 is rotatably mounted on the cage 2. The drive shaft 13 is connected to the rotating frame 11 via a belt. The air supply hood 3 is equipped with an air control component that controls the angle of the air guide plate 12.

[0046] The air control assembly includes a microcontroller 14 and a temperature and humidity probe 15 mounted on the air supply shroud 3. The data terminal of the temperature and humidity probe 15 is connected to the microcontroller 14. A motor 16 is mounted on the air supply shroud 3. A drive disk 17 is mounted on the output shaft of the motor 16. Driven disks 18 are fixedly mounted on both ends of the transmission shaft 13. The drive disk 17 and the driven disk 18 are coaxially arranged. Friction textures are provided on the surfaces of the drive disk 17 and the driven disk 18.

[0047] The temperature and humidity probe 15 monitors the temperature and humidity data of the air supply hood 3 in real time and transmits it to the microcontroller 14. The microcontroller 14 controls the motor 16 to rotate according to the preset threshold. The motor 16 drives the active disk 17 to rotate. The friction transmission between the active disk 17 and the driven disk 18 causes the transmission shaft 13 to rotate, and then drives the rotating frame 11 through the belt, thereby adjusting the angle of the air guide arc plate 12.

[0048] The upwind chamber is located near the surface of the grain pile and is mainly responsible for ventilation of the surface grain to prevent condensation and mold growth.

[0049] The downwind chamber extends to the bottom of the grain pile and is responsible for dissipating heat and moisture from the entire grain pile.

[0050] When the ventilation equipment is started, the motor 16 intelligently adjusts the angle of the air guide plate 12 according to the temperature and humidity distribution data of the grain pile, and then controls the air volume and air speed ratio of the upper and lower air chambers. For example, when the humidity at the bottom of the grain pile is high, the air volume of the lower air chamber is increased to achieve efficient ventilation.

[0051] This solution solves the problem of not being able to accurately adjust the ventilation effect based on the real-time temperature and humidity inside the grain warehouse. It can automatically adjust the ventilation status according to the actual environmental parameters, optimize the airflow direction and velocity inside the ventilation filter cartridge 8, greatly improve the accuracy and effectiveness of ventilation, effectively ensure the suitability of the grain storage environment, and reduce the risk of grain deterioration caused by unsuitable temperature and humidity.

[0052] Working principle and usage process of this utility model:

[0053] When the above-ground cage ventilation structure of this utility model is in operation, the airflow generated by the start of the ventilator 1 passes through the air supply hood 3 and is introduced into the cage body 2 through the magnetic snap-fit ​​connection between the outer splicing plate 23 and the inner splicing seat 24, realizing convenient splicing and flexible addition or removal of the cage body 2 according to the actual situation of the grain warehouse. The operator slides the adjustment frame 5 to drive the adjustment arc plate 6 to move, thereby changing the ventilation area, diameter and direction of the upper hole 4, and precisely controlling the ventilation volume and angle of the upper air chamber to meet different grain storage ventilation needs. The upper air chamber is mainly responsible for the ventilation of the surface of the grain pile to prevent condensation and mold. After the ventilation airflow enters the cage body 2, the air collecting hood 19 collects the airflow and drives the fan blades 21 to rotate. This drives the ventilation filter cartridge 8 to rotate, changing the connection between the inner filter hole 9 and the lower through hole 10 to regulate the ventilation volume of the lower air chamber. The upper and lower air chambers form a three-dimensional ventilation mode. The lower air chamber is responsible for expelling heat and moisture from the bottom of the grain pile. At the same time, the temperature and humidity probe 15 monitors the temperature and humidity data inside the air supply hood 3 in real time and transmits it to the microcontroller 14. The microcontroller 14 controls the motor 16 according to the preset threshold, which drives the transmission shaft 13 and the rotating frame 11 through the friction transmission between the active plate 17 and the driven plate 18, adjusting the angle of the guide plate 12, and intelligently regulating the air volume and wind speed ratio of the upper and lower air chambers to achieve efficient and precise ventilation and ensure a suitable grain storage environment.
