TECHNICAL FIELD
[0001] The utility model belongs to the technical field of ventilation structure, especially relates to a ventilation structure for closed cultivation facility. BACKGROUND
[0002] There are many cultivation methods for Dictyophora rubrovolvata, and since the required conditions for cultivation are relatively high, closed facilities with constant temperature and humidity are generally used for cultivation and management at present, such as common culture rooms, Irish greenhouse planting and intelligent shelter planting, etc., wherein in the Irish greenhouse and the intelligent shelter, most of them use layer rack type cultivation.
[0003] At present, in most cultivation facilities, the required ventilation pipe device (thick transparent plastic wind belt) is arranged at the middle position of the top layer of the shelter or greenhouse and the like. When the Dictyophora rubrovolvata mycelium is about to be twisted in the shelter, the ventilation pipe is used for ventilation, and in the process of use, the film hung outside the cultivation rack is opened every time and then the ventilation treatment is carried out, and the film opening and closing of small experimental shelters saves time. However, if large-scale industrial planting is carried out, the film opening and closing work is carried out every day, which not only wastes time but also wastes manpower. At the same time, during the twisting process, due to uneven wind, the twisting time of the mycelium placed in the innermost layer is inconsistent and uneven with the twisting time of the mycelium in the outer layer and the twisting time of the mycelium in the topmost layer and the bottommost layer.
[0004] The increase of the ventilation frequency causes the original twisted cultivation basket to lack water or the original base to be blown by wind for a long time, resulting in the phenomenon of the original base shrinking, which affects the yield and quality of the experimental bamboo flowers. The most important thing is the safety problem. Before cultivation in the closed facility, it is necessary to carry out disinfection and sterilization treatment by igniting fumigants and the like, and if the ignition material is not extinguished in time, a fire will be caused by the ignition of the plastic wind belt, which will cause a fire and the like.
[0005] The patent document with the publication number CN221532368U discloses a Dictyophora rubrovolvata edible fungus cultivation device, which comprises a culture box, a ventilation fan is installed on the top of the culture box, a ventilation channel is arranged on the rear side of the culture box, and a semiconductor temperature adjusting device is installed on the top plate and the bottom plate of the ventilation channel. The device can improve the smoothness of air circulation between the main bodies of the layers of trays, and make the substrate on the upper and lower sides contact with air, thereby improving the air permeability. However, the ventilation channel is not arranged corresponding to each layer of tray, which can easily cause the growth environment of the culture fungus in the upper and lower layers to be different from that of the culture fungus in the middle layer, thereby affecting the quality.
