Description

Technical Field

[0001] The utility model relates to the technical field of grain bin ventilation, and more specifically, to a grain bin ventilation device with an extended air outlet. Background Technique

[0002] A grain bin is a warehouse specifically used for storing grains, which has functions such as moisture-proof, pest-proof, and anti-corrosion to ensure that the stored grains can maintain their quality and safety for a long time. When storing grains, if the temperature and humidity are too high, it is easy to cause problems such as grain heating and mildew, and it is easy to breed pests and molds. Ventilation can destroy the living environment of pests and molds and effectively prevent the occurrence of pests and mildew. Ventilation can effectively adjust the temperature and humidity in the grain bin and keep them within a range suitable for grain storage.

[0003] Among them, the patent with the patent application number CN201720355473.2 discloses a grain bin ventilation device, which includes a plurality of air duct bodies that are axially fixedly connected in sequence to form a main air duct. Each air duct body is formed by bending a plate into a long strip-shaped arc-shaped plate member. A plurality of reinforcing ribs are arranged on the inner wall of the arc-shaped plate member to provide an internal support for the arc-shaped plate member and prevent the arc-shaped plate member from deforming;

[0004] By arranging a plurality of air duct bodies axially in sequence and fixedly connecting them to be installed at the bottom of the wall of the grain bin, the upper flanges of the air duct bodies are all abutted against the wall and fixedly installed by screws, and the lower flanges of the air duct bodies are all abutted against the ground and fixedly installed by screws, so that a transverse ventilation channel is formed between the inner sides of the plurality of air duct bodies and the wall and the ground. However, this structure is not easy to adjust the size of the air outlet during use, resulting in uncontrollable air flow during ventilation. At the same time, external dust is also easy to enter the grain bin during ventilation, reducing the quality of grain storage. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a grain bin ventilation device with an extended air outlet, aiming to solve the problems proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A grain bin ventilation device with an extended air outlet, including a support frame, and an adjustment and diversion assembly is arranged on the support frame;

[0007] The adjustment and diversion assembly includes a connecting plate arranged on the top of the support frame. A light-transmitting plate is arranged on the connecting plate. A filter screen for filtering air flow is arranged on the outside of the support frame, and the top of the filter screen extends to the bottom of the connecting plate;

[0008] Two reinforcing cross plates are arranged in the middle of the support frame, and dislocation notches are formed through each of the reinforcing cross plates. An electric push rod is arranged in the dislocation notch. The output end of the electric push rod is rotatably connected with a pin connector through a pin, and the pin connector is installed on the connecting plate.

[0009] It can be seen that in the above technical solution, the connecting plate rotates along the axis point of the connection between the connecting plate and the hinge, so that the connecting plate can be adjusted at an appropriate angle, the space between the connecting plate and the support frame is adjusted, and then the function of adjusting the air outlet size is realized. And through the setting of the filter screen, the filter screen can always filter the air flow passing between the connecting plate and the support frame, preventing impurities in the air flow from entering the granary.

[0010] Optionally, in a possible implementation manner, a support shaft seat is arranged outside the electric push rod. The support shaft seat extends to the reinforcing cross plate and is slidably connected with the reinforcing cross plate. Docking heads are arranged at both ends of the reinforcing cross plate, and each docking head is arranged on the support frame and is detachably connected with the support frame. The connecting plate is rotatably connected with the support frame through a hinge. A sealing gasket is arranged at the top of the support frame, and a diversion cover is arranged at the bottom of the support frame. The vertical cross-sectional shape of the diversion cover is trapezoidal, and the diversion cover is detachably connected with the support frame.

[0011] It can be seen that in the above technical solution, when the connecting plate returns to its original position, the filter screen will be folded together, and then the dust adhering to the filter screen during filtration will fall due to the torsion force during the deformation of the filter screen, preventing the dust from blocking the filter screen and affecting the ventilation effect. At the same time, through the sealing gasket, it is convenient to fill the gap between the connecting plate and the support frame when the connecting plate is closed, ensuring its sealing performance and preventing external rainwater from seeping into the granary.

[0012] The technical effects and advantages of the present utility model:

[0013] By providing an adjustable diversion component, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the connecting plate rotates along the axis point of the connection between the connecting plate and the hinge, so that the connecting plate can be adjusted at an appropriate angle, the space between the connecting plate and the support frame is adjusted, and then the function of adjusting the air outlet size is realized. And through the setting of the filter screen, the filter screen can always filter the air flow passing between the connecting plate and the support frame, preventing impurities in the air flow from entering the granary.

[0014] At the same time, when the connecting plate returns to its original position, the filter screen will be folded together, and then the dust adhering to the filter screen during filtration will fall due to the torsion force during the deformation of the filter screen, preventing the dust from blocking the filter screen and affecting the ventilation effect. At the same time, through the sealing gasket, it is convenient to fill the gap between the connecting plate and the support frame when the connecting plate is closed, ensuring its sealing performance and preventing external rainwater from seeping into the granary.

And through the setting of the filter screen 4, the filter screen 4 can always filter the air flow passing between the connecting plate 2 and the support frame 1, preventing impurities in the air flow from entering the grain storage, and the specific structure of the component is as follows;

[0024] The air guiding and adjusting assembly includes a connecting plate 2 arranged on the top of the support frame 1. A light-transmitting plate 3 is arranged on the connecting plate 2. A filter screen 4 for filtering air flow is arranged on the outer side of the support frame 1, and the top of the filter screen 4 extends to the bottom of the connecting plate 2;

[0025] Two reinforcing cross plates 5 are arranged in the middle of the support frame 1, and dislocation notches 6 are formed through each of the reinforcing cross plates 5. Electric push rods 7 are arranged in the dislocation notches 6. The output end of the electric push rod 7 is rotationally connected to a pin connector 13 through a pin, and the pin connector 13 is installed on the connecting plate 2.

[0026] Support shaft seats 8 are arranged on the outer sides of the electric push rods 7.
