Description

Technical Field

[0001] The present invention relates to the technical field of mushroom cultivation, and in particular to a fresh air system for a mushroom house. Background Art

[0002] A mushroom house is an artificial space used in the mushroom cultivation process to artificially control various growth conditions to ensure that the mushrooms inside can enjoy a completely suitable growth environment and various nutrients. Mushrooms have high requirements for the environment when growing, so a fresh air system is usually installed to ensure a good air environment inside the mushroom house.

[0003] The main function of the fresh air system in the current mushroom room is to control the pressure difference between the room and the outside. On the one hand, it maintains a stable ecological environment in the room to prevent external bacteria from entering the room and polluting the mushrooms; on the other hand, it maintains the concentration of carbon dioxide in the room to promote the growth of mushrooms, and regularly disinfects the room to prevent staff from carrying other fungi and contaminating the mushroom room when picking.

[0004] Currently, existing fan control systems all judge the disinfection time, ventilation time and disinfection progress in the mushroom house through manual experience, and accurately record the current state of the mushroom house. It is impossible to know whether the conditions for picking are met, which leads to premature destruction of the internal environment of the mushroom house and the death of mushrooms. Summary of the invention

[0005] A technical problem to be solved by the present disclosure is that the current judgment of the environment in the mushroom house is based on manual experience, which cannot reasonably distinguish the state of the mushroom house and thus causes damage to the mushrooms.

[0006] In order to solve the above technical problems, the present disclosure provides a mushroom house fresh air system, which includes: The mushroom house is equipped with a fresh air fan and an exhaust fan inside, and the fresh air fan and the exhaust fan are arranged opposite to each other. The outside of the mushroom house is equipped with a fresh air system and an isolation door; Among them, the fresh air system is used to control the opening or closing of the fresh air fan and the exhaust fan according to the control signal. The fresh air system includes a disinfection module, an entry module, a cultivation module and an exit module to control the environment inside the mushroom house.

[0007] In some embodiments, in the aforementioned mushroom house fresh air system, the disinfection module is used to generate a disinfection signal to turn off the exhaust fan to maintain a disinfected environment in the mushroom house.

[0008] In some embodiments, in the aforementioned mushroom house fresh air system, the storage module is used to generate a sensing signal to put the fresh air fan in an operating state and the exhaust fan in an off state, and the internal environment of the mushroom house is in a first state; Wherein, in the first state, the air pressure inside the mushroom house is greater than the air pressure outside the mushroom house, so as to prevent the gas outside the mushroom house from entering into the mushroom house and causing pollution to the mushroom house.

[0009] In some embodiments, in the aforementioned mushroom house fresh air system, the concentration of carbon dioxide in the mushroom house in the first state is 1200ppm-1700ppm.

[0010] In some embodiments, in the aforementioned mushroom house fresh air system, the pressure difference between the inside and outside of the mushroom house is 10Pa in the first state.

[0011] In some embodiments, in the aforementioned mushroom house fresh air system, the fresh air fan is turned on for 10 minutes and turned off for 50 minutes in the first state.

[0012] In some embodiments, in the aforementioned mushroom house fresh air system, the outbound module is used to generate a sensing signal to put the fresh air fan in a closed state and the exhaust fan in a running state, and the internal environment of the mushroom house is in a second state; Among them, in the second state, the air pressure inside the mushroom house is lower than the air pressure outside the mushroom house, so as to prevent the gas inside the mushroom house from leaking out and causing pollution.

[0013] Through the above technical scheme, the present disclosure provides a mushroom house fresh air system, through which the fresh air system of the mushroom house can control the opening and closing of the fresh air fan and the exhaust fan, and can control the disinfection module to disinfect the mushrooms in the mushroom house when the mushroom house is in a disinfection state, and at this time the staff can be alerted to enter to avoid harm to the staff; after the disinfection is completed, the fresh air system can be set to the storage mode, at which time the staff can smoothly enter the mushroom house, put the mushrooms into the mushroom house, and maintain the positive pressure environment in the mushroom house through the fresh air fan. When cultivating the mushrooms in the mushroom house, the fresh air system is in the cultivation mode, and the environment in the mushroom house is accurately controlled in the cultivation mode to promote the growth of the mushrooms. Finally, the storage mode is set to enter the mushroom house. The fresh air system can be used for collection and the boundaries of different stages of the mushroom house can be clearly divided under the control of the mushroom house, so that the staff can accurately control the status of the mushroom house without having to record it separately. When facing a large number of mushroom houses, the current status of each mushroom house can be clearly identified, which reduces the pressure on the staff and is beneficial to the growth of mushrooms in each mushroom house. At the same time, the operation is simple. Only the fresh air system needs to be controlled to uniformly interact with the fresh air fan and the exhaust fan, thereby realizing precise control of the internal environment of the mushroom house. Therefore, no matter whether it is the disinfection time, ventilation time or the pressure difference inside and outside the mushroom house, it can be accurately recorded and controlled. Therefore, the time for picking mushrooms can also be accurately obtained, and the mushrooms can be collected with high quality, which improves the yield rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Embodiment 1 Reference Figure 1-Figure 3 The present embodiment discloses a fresh air system for a mushroom house, which includes a mushroom house 1. A fresh air fan 2 and an exhaust fan 3 are arranged inside the mushroom house 1, and the fresh air fan 2 and the exhaust fan 3 are arranged opposite to each other. A fresh air system and an isolation door 4 are arranged outside the mushroom house 1; wherein the fresh air system is used to control the opening or closing of the fresh air fan 2 and the exhaust fan 3 according to a control signal, and the fresh air system includes a disinfection module, a storage module, a cultivation module and a storage module to control the environment inside the mushroom house 1.

[0025] Specifically, in order to solve the problem that the existing judgment of the environment in the mushroom house is based on manual experience, and the status of the mushroom house 1 cannot be rationally distinguished, thereby causing damage to the mushrooms, the mushroom house 1 fresh air system provided in this embodiment, through various modules in the fresh air system, switches the environment in the mushroom house 1 into a disinfection state, a storage state, a cultivation state and a storage state, and the fresh air fan 2 and the exhaust fan 3 are turned on and off in different states in a targeted manner, thereby realizing the change and maintenance of the environment in the mushroom house 1. On the one hand, it enables the staff to accurately control the production status of the mushroom house 1, and on the other hand, reasonable control of the environment in the mushroom house 1 can also achieve efficient production of mushrooms.

[0026] Among them, the mushroom house wind system provided in this embodiment is mainly used in the production and processing of mushrooms, and of course it can also be applied to other types of crops that require special growing conditions. The fresh air fan 2 is a general term for air-discharging devices. The fresh air fan 2 is used to filter, dehumidify or humidify, heat up or cool down the external air to absorb the external air into the room to maintain the indoor environment. When mushrooms are cultivated, there are certain requirements for the temperature, humidity and carbon dioxide concentration in the environment. The fresh air fan 2 can be used to exchange the gas in the mushroom house 1 to adjust the environment inside the mushroom house 1 and promote the growth of mushrooms. White mushrooms, oyster mushrooms and shiitake mushrooms all need to maintain a temperature of 25 degrees Celsius and an overall humidity of 90 percent; the exhaust fan 3 is a general term for exhaust gas devices, which are used to discharge the gas in the mushroom house 1 to the outside, and the position of the exhaust fan 3 is arranged relative to the position of the fresh air fan 2. It can be understood that in order to achieve the gas in the mushroom house 1, Efficient circulation, the gas sucked in by the fresh air fan 2 will enter the mushroom house 1 from one end inside the mushroom house 1, and when exhaust is needed, the gas will be discharged from the end far away from the fresh air fan 2, so as to achieve the purpose of air circulation, which is helpful for the gas to pass through the entire mushroom house 1 completely, and ensure the stability of the internal environment of the mushroom house 1; the isolation door 4 is a general term for environmental devices used to seal the mushroom house 1. Since mushrooms are growing crops and have harsh environmental requirements, except for placing mushroom seedlings and taking out finished products, it is necessary to enter the mushroom house 1, and the environment in the mushroom house 1 needs to be maintained mechanized at other times. Therefore, the isolation door 4 can divide the internal and external environments, so that an independent space is formed in the mushroom house 1, which is conducive to the growth of mushrooms. At the same time, the isolation door 4 is connected to an external controller and is opened or closed according to a control signal.

[0027] In addition, the fresh air system is located outside the mushroom house 1 and is used to control the fresh air fan 2, the exhaust fan 3 and the isolation door 4. The exhaust fan 3 system can be set to four modes, namely, disinfection mode, storage mode, cultivation mode and storage mode. In different modes, the fresh air fan 2, the exhaust fan 3 and the isolation door 4 operate in different ways.

[0028] Among them, the disinfection module is used to generate a disinfection signal to keep the exhaust fan 3 in a closed state to maintain a disinfected environment in the mushroom house 1. Specifically, the mushroom house 1 needs to be disinfected before the mushroom bags are placed to keep the environment in the mushroom house 1 clean and prevent damage to the mushroom bags. The staff ignites the disinfectant and places an open container with the disinfectant inside the mushroom house 1. The smoke generated by the disinfectant will fill the entire mushroom house 1 and fully disinfect the interior of the mushroom house 1. This process lasts for 30 minutes to 50 minutes. The disinfection is completed when the smoke in the mushroom house 1 dissipates.

[0029] Secondly, the mushroom bag placement stage begins. The storage module is used to generate a sensing signal to keep the fresh air fan 2 in operation and the exhaust fan 3 in an off state. It can be understood that after the disinfection is completed, the isolation door 4 is opened by an external controller, and the staff quickly transports the mushroom bags into the mushroom house 1, and then closes the isolation door 4 to reduce the contact between the inside of the mushroom house 1 and the external environment. At the same time, the fresh air fan 2 is operated to make the air pressure inside the mushroom house 1 greater than the air pressure outside the mushroom house 1, so as to prevent the gas outside the mushroom house 1 from entering the mushroom house 1 and causing pollution to the mushroom house 1, thereby destroying the growth of mushrooms. After the staff has completed the placement, they quickly leave the mushroom house 1, and the fresh air fan 2 continues to operate. Under the cultivation module, the exhaust fan 3 can also be controlled separately. The specific mushroom house 1 can perform separate detections on the carbon dioxide concentration, exhaust time and environmental pressure, and cooperate with the operation of the fresh air fan 2 to keep the environment in the mushroom house 1 in a stable state.

[0030] It can be understood that the carbon dioxide concentration in the environment to be maintained in the mushroom house 1 is 1200ppm-1700ppm to ensure the normal growth and development of mushrooms. Specifically, a carbon dioxide concentration sensor is provided inside the mushroom house 1 to detect the carbon dioxide concentration at any time, and the data is transmitted to the fresh air system for intuitive information. Therefore, if the carbon dioxide concentration is too high, the exhaust fan 3 is turned on, and when the carbon dioxide concentration becomes low, the exhaust fan 3 is turned off, and the fresh air fan 2 continues to inhale gas to increase the carbon dioxide concentration in the mushroom house 1 to ensure the normal growth of the mushroom bag. At the same time, the size of the carbon dioxide setting value can be adjusted according to different types of mushrooms; at the same time, the pressure difference between the inside and outside of the mushroom house 1 is 10Pa, and this pressure difference can avoid external Even if miscellaneous bacteria leak into the mushroom house 1, it will not affect the growth of the mushroom bags. At the same time, this range is a dynamically adjusted state. Since the fresh air fan 2 is continuously running, the exhaust fan 3 will use this as a sensing value. When the pressure difference is too large, the exhaust fan 3 will start to reduce the pressure in the mushroom house 1; when the pressure difference is lower than the preset value, the exhaust fan 3 will be turned off, and the pressure in the mushroom house 1 will be increased by the continuous suction of gas by the fresh air fan 2 to maintain the pressure difference; in this state, starting from the time the staff leaves the mushroom house 1, the exhaust fan 3 will run continuously for 10 minutes and the shutdown time will be 50 minutes. In conjunction with the suction of the fresh air fan 2, the environment in the mushroom house 1 can be maintained. This interval time forms a complete cycle, so that the environment of the entire mushroom house 1 is in the best growth environment for the mushroom bags.

[0031] In addition, when collecting mushrooms, the outbound module in the fresh air system is set to the outbound mode. At this time, the fresh air fan 2 is in the closed state, the exhaust fan 3 is in the running state, and the isolation door 4 is in the open state. Therefore, the air pressure inside the mushroom house 1 is lower than the air pressure outside the mushroom house 1. It can be understood that since the internal environment after the growth of mushrooms is completed is full of many other bacteria, when collecting mushrooms, the bacteria in the mushroom house 1 will leak, and the direct leakage from the fresh air fan 2 or the isolation door 4 will pollute the overall internal environment. The fresh air fans 2 of the remaining mushroom houses 1 are easy to inhale the bacteria that cannot be filtered, causing the death of the mushrooms. It can be but not limited to one mushroom house 1. Each mushroom house 1 is set, and the air outlet end of the exhaust fan 3 is set outside, so that the gas in the mushroom house 1 can be directly discharged to the outside, which will not pollute the indoor air. At the same time, the fresh air systems of each mushroom house 1 are relatively set, that is, the staff can control the mushroom houses 1 on both sides at a time and observe the current state of the mushroom house 1 in real time. There is no need to record the real-time state of each mushroom house 1 separately, which reduces the difficulty of operation for the staff.
