Description

Technical Field

[0001] This utility model relates to the field of agricultural facility renovation technology, and in particular to a dual-purpose greenhouse for tobacco floating seedling cultivation and shiitake mushroom fruiting. Background Technology

[0002] Traditional tobacco seedling greenhouses are mainly used for tobacco seedling cultivation and experimental research. However, with changes in market demand and adjustments in tobacco planting areas, some seedling greenhouses are now idle or underutilized. Shiitake mushrooms, as a high-value edible fungus, require specific environmental conditions for cultivation. Existing shiitake mushroom cultivation greenhouses are costly to construct and require significant land resources. Therefore, how to transform idle seedling greenhouses into facilities suitable for shiitake mushroom cultivation has become an urgent problem to be solved.

[0003] Currently, existing tobacco seedling greenhouses can control light intensity, meeting the low-light environment required for shiitake mushroom growth. Openable ventilation windows on both sides ensure air circulation. However, these greenhouses lack effective insulation and humidity control systems, failing to meet the conditions for shiitake mushroom fruiting from November to March. Therefore, to advance industry technology and better integrate the use of floating tobacco seedling greenhouses with shiitake mushroom fruiting, thereby enhancing core technological competitiveness, this application proposes a new implementation scheme that differs from existing dual-purpose greenhouse structures and applications. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing lack of effective heat preservation facilities and humidity control systems makes it impossible to meet the conditions for shiitake mushroom fruiting from November to March, and proposes a dual-purpose greenhouse for tobacco floating seedling cultivation and shiitake mushroom fruiting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-purpose greenhouse for tobacco floating seedling cultivation and shiitake mushroom fruiting includes a frame. A crossbeam is fixedly connected to the inner top wall of the frame, and multiple columns are fixedly connected to the bottom of the crossbeam. Multiple adjusting hooks are fixedly connected to both sides of each column. An exhaust fan is fixedly connected to the inner wall of one end of the frame, and a film is fixedly connected to the outer wall of the frame. Multiple ventilation openings are located at one end of the film, outside the exhaust fan. Insulation layers are provided on both inner walls of the frame. Two shading films are provided at the top inside the frame. A main pipe is fixedly connected between the columns, and multiple spray pipes are sealed and inserted into both sides of the main pipe. Multiple nozzles are sealed and inserted into the bottom of each spray pipe. Cultivation racks are suspended from the adjusting hooks, and multiple culture media are inserted into the cultivation racks. Multiple connecting rods are fixedly connected between two culture media, and ultraviolet disinfection lamps are fixedly connected to the bottom of the connecting rods.

[0007] Furthermore, the insulation layer has an arc-shaped structure.

[0008] Furthermore, the insulation layer is a foam board layer or an insulation cotton layer.

[0009] Furthermore, two sunshade films are provided on the top of the shed.

[0010] Furthermore, a carbon dioxide sensor is fixedly connected to the outer wall of the main pipeline.

[0011] Furthermore, a connector is sealed and plugged into one end of the main pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By hanging the cultivation rack on the adjustment hook and then inserting the culture medium into the cultivation rack, shiitake mushrooms are cultivated, thereby realizing the floating seedling cultivation of tobacco and the cultivation of shiitake mushrooms.

[0014] 2. The greenhouse is insulated by an insulation layer to maintain a suitable temperature. Water is then pumped into the main pipe and then into the spray nozzles through the spray pipes. The water is then sprayed from the nozzles onto the culture medium to provide moisture, thereby achieving the effect of heat preservation and moisture retention.

[0015] 3. The carbon dioxide concentration in the greenhouse is detected by a carbon dioxide sensor. When the carbon dioxide concentration in the greenhouse is too high, the processor controls the exhaust fan to start, and the exhaust fan ventilates the greenhouse through the ventilation opening, thereby better cultivating shiitake mushrooms.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 A dual-purpose greenhouse for tobacco floating seedling cultivation and shiitake mushroom fruiting includes a frame 1 and a processor. The top inner wall of the frame 1 is welded with a crossbeam 2, and multiple columns 3 are welded to the bottom of the crossbeam 2. Multiple adjusting hooks 4 are welded to both sides of the columns 3. An exhaust fan 6 is fixed to the inner wall of one end of the frame 1 by bolts. A film 7 is glued to the outer wall of the frame 1. Multiple ventilation openings 5 ​​are provided at one end of the film 7, and the ventilation openings 5 ​​are located outside the exhaust fan 6. Both inner walls of the frame 1 are provided with heat insulation layers 8, which insulate the greenhouse and maintain a suitable temperature range (15-25℃). Two shading films 9 are provided at the top inside the frame 1 to shade the shiitake mushrooms.

[0025] Multiple columns 3 are fixed together by bolts to form a main pipe 10. One end of the main pipe 10 is sealed with a connector 13. Multiple spray pipes 11 are sealed on both sides of the main pipe 10. Multiple nozzles 12 are sealed at the bottom of the spray pipes 11. The pump body draws water into the main pipe 10, and then the water flows through the spray pipes 11 into the nozzles 12. The water then flows from the nozzles 12 to the culture medium 18, thereby providing water to the culture medium 18.

[0026] A cultivation rack 15 is suspended on the adjusting hook 4. Multiple culture media 18 are inserted into the cultivation rack 15. The culture media 18 are inserted into the cultivation rack 15 to cultivate shiitake mushrooms. Multiple connecting rods 16 are fixed between two culture media 18 by bolts. Ultraviolet disinfection lamps 17 are fixed to the bottom of the connecting rods 16 by bolts. The culture media 18 are disinfected by ultraviolet disinfection lamps 17 before and after the mushrooms grow.

[0027] The insulation layer 8 has an arc-shaped structure and is composed of a foam board layer or an insulation cotton layer. Two shading films 9 are installed at the top inside the frame 1 to provide shade for the shiitake mushrooms. A carbon dioxide sensor 14 is bolted to the outer wall of the main pipe 10, utilizing the absorption characteristics of CO2 molecules for infrared light of a specific wavelength (4.26μm). Infrared light emitted by the light source passes through the gas chamber; CO2 absorbs some of the light energy, and the remaining light intensity is measured by the detector. By comparing the intensity difference between the incident and transmitted light, and combining this with Lambert-Beer's law, the concentration is calculated. The processor is electrically connected to the exhaust fan 6, the carbon dioxide sensor 14, and the ultraviolet disinfection lamp 17. The processor model is ARM9TDMI, and the carbon dioxide sensor 14 model is MH-Z19C.

[0028] The working principle of this embodiment is as follows: In use, the connector 13 is connected to the pump body, and the processor is electrically connected to the pump body. First, the cultivation rack 15 is hung on the adjustment hook 4. Then, the culture medium 18 is inserted into the cultivation rack 15 to cultivate shiitake mushrooms. During the cultivation process, the greenhouse is kept warm by the insulation layer 8, so that the greenhouse maintains a suitable temperature range (15-25℃). Then, the shiitake mushrooms are shaded by the shading film 9. Next, the processor controls the pump body to start, and the pump body draws water into the main pipe 10, and then into the nozzle 12 through the spray pipe 11. Then, the water flows from the nozzle 12 to the culture medium 18, thereby providing moisture to the culture medium 18. Next, the carbon dioxide sensor 14 detects the carbon dioxide concentration in the greenhouse. When the carbon dioxide concentration in the greenhouse is too high, the processor controls the exhaust fan 6 to start, and the exhaust fan 6 ventilates the greenhouse through the ventilation opening 5. Before and after the mushrooms emerge, the culture medium 18 is disinfected by the ultraviolet disinfection lamp 17.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
