Description

Technical Field

[0001] This utility model relates to the technical field of ventilation devices for edible mushroom houses, and more specifically, to a ventilation device with adjustable flow rate. Background Technology

[0002] Good ventilation is crucial for the growth and development of edible fungi during cultivation. The environment of the mushroom house needs to be controlled, including oxygen and carbon dioxide concentrations, as well as temperature and humidity, to meet the needs of different types of edible fungi at various growth stages. However, existing ventilation devices are difficult to fully meet the special requirements of mushroom houses.

[0003] Traditional ventilation systems typically use fixed vents. Once production is complete, the size and ventilation area of ​​these vents are constant, resulting in a lack of adjustable ventilation area. Consequently, the ventilation volume cannot be adjusted in real-time to adapt to the complex and ever-changing environment within the mushroom cultivation room. Edible fungi have vastly different oxygen and carbon dioxide requirements at different growth stages. For example, oxygen requirements are relatively low during mycelial growth, while a large amount of fresh air is needed during fruiting body formation and development. Insufficient ventilation leads to carbon dioxide accumulation, affecting the quality and yield of the mushrooms. Therefore, we propose a ventilation system with flexibly adjustable ventilation volume. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Please see Figures 1-5This utility model provides a technical solution: a ventilation device with adjustable flow rate, including a main air duct 1, a plurality of secondary pipes 10 fixedly installed on the main air duct 1, and a delivery pipe 2 connected to the end flange of the secondary pipes 10, which facilitates the connection operation of the pipeline and enables the ventilation device to have the basis for multi-zone air supply.

[0028] Specifically, the end flange of the conveying pipe 2 is connected to the air outlet pipe 21. A fixing block 22 is fixedly installed on the pipe body of the air outlet pipe 21. The inside of the air outlet pipe 21 is rotatably connected to the sealing plate 23 through the rotating shaft 24. A rectangular groove 241 is provided in the rod body at one end of the rotating shaft 24. A servo motor 25 is fixedly installed on the side of the fixing block 22. The output shaft of the servo motor 25 passes through the fixing block 22 and is rotatably connected to the fixing block 22. A through hole is provided in the fixing block 22 for the output shaft of the servo motor 25 to pass through. A rectangular rod 251 is fixedly installed at the end of the output shaft of the servo motor 25. The rectangular rod 251 is located in the rectangular groove 241 and is inserted into the rectangular groove 241.

[0029] In this embodiment, the size of the sealing disc 23 is adapted to the size of the air outlet pipe 21. The cross-sections of the rectangular rod 251 and the rectangular groove 241 are both rectangular, and the size of the rectangular rod 251 is adapted to the size of the rectangular groove 241. When the sealing disc 23 is rotated to a horizontal position, the air volume in the air outlet pipe 21 reaches its maximum. When the sealing disc 23 is rotated to a vertical position, the sealing disc 23 performs a sealing operation on the air outlet pipe 21. This allows the ventilation volume of each area to be quickly adjusted according to actual needs in different places such as mushroom houses, meeting the requirements of oxygen and carbon dioxide concentrations at different growth stages, promoting the healthy growth of edible fungi, and improving yield and quality.

[0030] Specifically, multiple lifting rings 20 are detachably connected to the conveying pipe 2. A lifting rod 201 is fixedly installed at the top of the lifting ring 20, and a fixing plate 202 is fixedly installed at the top of the lifting rod 201. The lifting ring 20 has a semi-circular cross-section and is fitted onto the lower half of the conveying pipe 2 to support it. The fixing plate 202 is fixedly installed on the corresponding external frame to achieve suspension support operation, ensuring that the device remains stable during operation, avoiding the impact of shaking on the ventilation effect, ensuring the reliable operation of the ventilation device, and reducing maintenance costs.

[0031] Furthermore, an air inlet hood 11 is fixedly installed at the air inlet end of the main air duct 1, an air inlet cylinder 12 is fixedly installed at the end of the air inlet hood 11, and a fan 13 is fixedly installed on the inner wall of the air inlet cylinder 12, thereby realizing the intake and delivery of air.

[0032] In addition, a conical filter cylinder 17 is provided at the front end of the air inlet duct 12. Multiple support rods 16 are fixedly installed on the conical filter cylinder 17. A support ring 121 is fixedly installed at the front end of the air inlet duct 12, and a fixing ring 15 is fixedly installed at the rear end of the conical filter cylinder 17. The ends of the support rods 16 are fixedly installed on the front side of the fixing ring 15. The fixing ring 15 is detachably connected to the front side of the support ring 121. A sealing gasket 14 is provided between the fixing ring 15 and the support ring 121 to effectively filter impurities and bacteria in the air. The detachable fixing ring 15 facilitates cleaning and replacement of the conical filter cylinder 17, ensuring clean air entering the mushroom house, reducing the risk of bacterial contamination, providing a good air environment for the growth of edible fungi, and improving the environmental quality of the mushroom house.

[0033] It is worth noting that the cone-shaped filter cylinder 17 is truncated cone-shaped, which helps to increase the ventilation area and make the air intake smoother.

[0034] Finally, it should be noted that the fan 13, servo motor 25 and corresponding external control system involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0035] When using the flexible ventilation device of this utility model, the fan 13 is started, and the outside air is drawn in by the fan 13 through the air inlet hood 11 and the air inlet duct 12. After passing through the conical filter screen 17 to filter impurities and bacteria, it enters the main air duct 1, and then flows through the secondary pipe 10 and the delivery pipe 2 to the air outlet duct 21. To adjust the ventilation volume of a certain area, the corresponding servo motor 25 on the air outlet duct 21 is turned on. Its output shaft drives the rectangular rod 251 to rotate. Because the rectangular rod 251 is inserted and matched with the rectangular groove 241 in the rotating shaft 24, it drives the rotating shaft 24 and the sealing plate 23 to rotate. When the sealing plate 23 is rotated to the horizontal position, the air volume of the air outlet duct 21 is maximized; when rotated to the vertical position, the air outlet duct 21 is blocked. In this way, the ventilation volume can be flexibly adjusted according to the needs of different growth stages of the edible fungus house.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
