Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse ventilation devices, in particular to a ventilation mechanism for an edible fungus cultivation shed. Background Art

[0002] Mushroom greenhouses are important facilities for mushroom cultivation, providing a relatively stable spatial environment for the growth of edible fungi. Throughout the growth cycle of edible fungi, the environmental conditions of the greenhouse have a crucial impact on their yield and quality.

[0003] During the growth of edible fungi, greenhouses require good ventilation. Ventilation ensures fresh air and reduces the concentration of harmful gases, which is crucial for the healthy growth of edible fungi. However, edible fungi have very strict requirements for the temperature and humidity environment within the greenhouse. Drastic fluctuations in temperature and humidity can inhibit their growth and even cause their death. Especially in winter, when ventilation is activated, the influx of cold air from outside can cause the temperature inside the greenhouse to drop sharply, significantly affecting the edible fungi.

[0004] Traditional mushroom greenhouse ventilation systems have significant flaws. They often simply feature air inlets and outlets, lacking temperature and humidity compensation mechanisms. During winter ventilation, these systems are unable to effectively regulate the temperature and humidity of the air entering the greenhouse. The influx of cold air severely disrupts the previously stable environment within the greenhouse, affecting the normal growth and development of mushrooms and, in turn, the economic benefits of mushroom cultivation.

[0014] (Three) technical effects

[0015] Compared with the prior art, the utility model has the advantages of:

[0016] 1. The ventilation mechanism can effectively maintain the stability of the temperature and humidity in the greenhouse.

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] Combined with attachment Figure 1 To the attached Figure 5A ventilation mechanism for an edible fungus cultivation shed comprises a shed body 1 and an air inlet 2 and an air outlet 3 arranged at both ends of the shed body 1. An exhaust fan 4 is fixedly arranged inside the air outlet 3. An insect and dustproof net 5 is provided inside the air inlet 2 near the outside of the shed body 1. One end of the air inlet 2 located inside the shed body 1 is connected in sequence with a temperature control chamber 6 and a humidity control chamber 7. A temperature compensation structure is provided inside the temperature control chamber 6, and a humidity compensation structure is provided inside the humidity control chamber 7. The temperature compensation structure and the humidity compensation structure are both electrically connected to a controller. A dustproof net 12 is fixed at the outlet of the humidity control chamber 7, and a sealing cover is provided on the outside of the air outlet 3.

[0030] In this embodiment, as a preferred technical solution, the temperature compensation structure includes a temperature sensor 8 and a heating element 9. The temperature sensor 8 is fixed inside the air inlet 2 to detect the temperature of the incoming air. The heating element 9 adjusts the temperature of the incoming air. The heating element 9 and the temperature sensor 8 are both electrically connected to the controller, and the heating element is an electric heating wire.

[0031] In this embodiment, as a preferred technical solution, the humidity compensation structure includes a humidity sensor 10 and a humidifying element 11. The humidity sensor 10 is fixed inside the air inlet 2 to detect the humidity of the incoming air. The humidifying element adjusts the humidity of the incoming air. The humidity sensor 10 and the humidifying element 11 are both electrically connected to the controller. The humidifying element 11 is an ultrasonic humidifier, and the water inlet end of the ultrasonic humidifier is connected to an external water source through a hose.

[0032] The working principle of the ventilation mechanism of the edible fungus cultivation shed of the present invention is as follows: during ventilation, air enters from the air inlet 2, and the insect and dustproof net 5 on the outside of the air inlet 2 can prevent pests and dust from entering. The incoming air is first detected by a temperature sensor and a humidity sensor. The temperature sensor 8 detects the air temperature in real time and transmits the signal to the controller. If the temperature is lower than the set value, the controller activates a heating element 9 such as an electric heating wire to heat the air entering the temperature control chamber 6, so that the air temperature reaches a range suitable for the growth of edible fungi. The air passing through the temperature control chamber 6 then enters the humidity control chamber 7. The humidity sensor 10 detects the air humidity and feeds the information back to the controller. If the humidity is insufficient, the controller controls the humidifying element 11 to humidify the air entering the humidity control chamber. The air after temperature and humidity adjustment passes through the dustproof net 12 at the outlet of the humidity control chamber 7 and enters the shed body 1. The air in the shed body 1 can be discharged through the exhaust port 3 and the exhaust fan 4, thereby achieving ventilation and maintaining a suitable temperature and humidity environment in the shed.

[0033] The working process of the ventilation mechanism of the edible fungus cultivation shed of the utility model is as follows:

[0034] 1. Ventilation starting stage: open the exhaust fan 4, make the air in the greenhouse body 1 discharge from the exhaust port 3, at this time, the negative pressure is formed in the greenhouse, and the external air enters from the air inlet 2.

[0035] 2. Air filtering stage: when the external air enters the air inlet 2, it first passes through the insect and dust prevention net 5, and most of the dust and pests are blocked outside the greenhouse.

[0036] 3. Temperature regulation stage: after the air enters, the temperature sensor 8 detects the air temperature and transmits the detected temperature signal to the controller, if the detected temperature is lower than the preset suitable temperature value for the growth of edible fungi, the controller starts the heating element 9 to heat the air until the temperature reaches the appropriate range.

[0037] 4. Humidity regulation stage: after the temperature of the air entering the humidity control chamber 7 is adjusted by the temperature control chamber 6, the humidity sensor 10 detects the air humidity and sends the humidity signal to the controller, if the detected humidity is lower than the preset value, the controller controls the humidifying element 11 to work, and the air is humidified to meet the growth requirements of edible fungi.

[0038] 5. Air entering the greenhouse stage: after the temperature and humidity of the air are adjusted, the air enters the greenhouse body 1 through the dust prevention net 12 at the outlet of the humidity control chamber 7, and provides a suitable air environment for the growth of edible fungi. During the ventilation process, the controller (PLC controller) continuously receives the signals of the temperature sensor 8 and the humidity sensor 10, and adjusts the working state of the heating element 9 and the humidifying element 11 in real time according to the needs, to ensure the stability of the temperature and humidity in the greenhouse. When the ventilation is finished, the exhaust fan 4 is closed, the sealing cover outside the exhaust port 3 is closed, and the sealing cover outside the air inlet can also be designed to maintain the stability of the environment in the greenhouse.

[0039] The above describes the utility model and its implementation, which is not limited, and the drawings shown are only one of the embodiments of the utility model, and the actual structure is not limited. In general, if a person skilled in the art is inspired, without departing from the purpose of the utility model, without creative design, similar structure and embodiments of the technical scheme can be designed, which should belong to the protection scope of the utility model.
