Detailed implementation manners

[0024] To enable those skilled in the art to better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0025] The embodiment of the present application provides an edible mushroom cultivation device, which can solve the problem of large cost investment in building a standard mushroom house in the related art.

[0026] In edible mushroom cultivation, generally bag cultivation is adopted. The culture medium is prepared, bagged, sterilized, inoculated, and after the mycelium is cultured to maturity, it enters the fruiting stage. In the fruiting stage, environmental factors such as the external environmental temperature, humidity, light, and carbon dioxide concentration have important effects on the differentiation and development of edible mushroom entities, and different edible mushrooms have significant differences in the requirements for environmental conditions.

[0027] During production, it is necessary to regulate temperature, humidity, air, light, and environmental cleanliness according to the requirements of different types of edible fungi for environmental conditions during their growth and development. Common mushroom-growing facilities mainly include simple greenhouses, mushroom-growing rooms, etc. Traditional mushroom-growing greenhouses are suitable for shiitake mushrooms, ganoderma lucidum, etc. that have less strict requirements for environmental conditions, and the edible fungi themselves have strong adaptability to changes in environmental conditions and certain resistance to miscellaneous bacteria in the environment. Mushroom-growing rooms are suitable for varieties such as enoki mushrooms and seafood mushrooms that have relatively strict requirements for environmental conditions. Production enterprises have relatively high requirements for production efficiency and must achieve high yields and quality under suitable temperature, humidity, air, light, and relatively high cleanliness environmental conditions to maximize economic benefits. Rare edible fungi varieties have extremely demanding requirements for environmental conditions, and the conditions of mushroom-growing greenhouses are difficult to meet the production environmental requirements. Generally, by building standard mushroom-growing rooms and using a variety of sensors and control equipment to finely regulate environmental conditions, the relatively high construction and operation costs of mushroom-growing rooms have become one of the important reasons restricting the development of the industry.

[0028] Regarding the problem of the large cost investment in building standard mushroom-growing rooms. Refer to Figures 1 to 3 , an embodiment of the present application provides an edible fungus cultivation device, which includes: a cultivation rack 3, a cultivation box 5, a water supply component, and a gas supply component. The cultivation box 5 is arranged on the cultivation rack 3. A fungus bag 9 is arranged inside the cultivation box 5, and a drain port is arranged on the cultivation box 5. One end of the water supply component is provided with a water supply port, and the water supply port is located inside the cultivation box 5. One end of the gas supply component is provided with a gas supply port, and the gas supply port is located inside the cultivation box 5.

[0029] In the present application, by setting the cultivation rack 3, the cultivation box 5, the water supply component, and the gas supply component, the environmental conditions required for the growth of edible fungi are created. A fungus bag 9 is arranged in each cultivation box 5, greatly reducing the probability of contamination by miscellaneous bacteria, eliminating the cost investment in building standard mushroom-growing rooms, improving the cultivation success rate, and further increasing economic benefits.

[0030] Among them, the cultivation rack 3 is made of aluminum alloy or stainless steel, which can adapt to the dark and humid environment of the cultivation room; a hanging rack 4 is arranged on the cultivation rack 3 to facilitate hanging the cultivation box 5 onto the cultivation rack 3 or removing it from the cultivation rack 3. In addition, a lamp strip is also arranged on the cultivation rack 3 to provide lighting services for operators.

[0031] In this embodiment, the length, width, and height of the culture box 5 are all greater than or equal to 15 cm. One or more edible mushroom bags 9 are placed in the culture box 5, and the bags 9 are filled with mushroom material. Further, a cover plate 11 is provided on the culture box 5. The culture box 5 and the cover plate 11 are made of transparent plastic. Ventilation holes 13 are provided on both the culture box 5 and the cover plate 11, and the diameter of the ventilation holes 13 is 1 - 2 cm. An outgrowing opening 12 is also provided on the mushroom bag 9. When using this edible mushroom cultivation device, after cutting the outgrowing opening 12 in the middle of the mushroom bag 9, the mushroom bag 9 is placed into the culture box 5, and then the culture box 5 is hung on the cultivation rack 3. The water supply component and the air supply component are connected, and the appropriate humidity and air environment are provided for the growth of the edible mushrooms through the water supply component and the air supply component.

[0032] Among them, the water supply component includes: a water tank 15, a main water supply pipe 1, and a branch water supply pipe 6. The main water supply pipe 1 is connected to the water tank 15; the branch water supply pipe 6 is connected to the main water supply pipe 1, and a water supply port is provided at one end of the branch water supply pipe 6. That is, water is supplied from the water tank 15 to the main water supply pipe 1, and then through the branch water supply pipe 6, water can flow into the interior of the culture box 5 from the water supply port, providing the appropriate humidity for the growth of the edible mushrooms. The purpose of providing a drainage port on the culture box 5 is to allow the excess water to flow out, preventing water from accumulating inside the culture box 5.

[0033] The air supply component includes: an air supply pump 14, a main air supply pipe 2, and a branch air supply pipe 7. The main air supply pipe 2 is connected to the air supply pump 14; the branch air supply pipe 7 is connected to the main air supply pipe 2, and an air supply port is provided at one end of the branch air supply pipe 7. Gas is provided into the culture box 5 through the air supply pump 14, and the gas enters the interior of the culture box 5 after passing through the main air supply pipe 2 and the branch air supply pipe 7, providing the appropriate air environment for the growth of the edible mushrooms.

[0034] Based on the above embodiment, in this embodiment, a plurality of culture boxes 5 are provided. The plurality of culture boxes 5 are spaced apart from top to bottom on the cultivation rack 3, forming a cultivation module.

[0035] Specifically, as Figure 3 shown, the cultivation rack 3 is provided with multiple layers, and each layer is provided with a culture box 5. A plurality of culture boxes 5 that are spaced apart from top to bottom and correspond in position form a cultivation module; on the cultivation rack 3, a plurality of cultivation modules are provided at horizontal intervals.

[0036] In this embodiment, the water supply port is arranged inside the topmost culture box 5 in the cultivation module, and a branch drainage pipe 8 is provided between two adjacent culture boxes 5. One end of the branch drainage pipe 8 is connected to the drainage port of the upper culture box 5 among two adjacent culture boxes 5, and the other end is arranged inside the lower culture box 5 among two adjacent culture boxes 5.

[0037] That is, in this embodiment, the branch water supply pipe 6 of the water supply assembly extends into the innermost cultivation box 5 of the cultivation module. Water is supplied to the innermost cultivation box 5 of the cultivation module through the water tank 15, the main water supply pipe 1, and the branch water supply pipe 6. Then, after the excess water is discharged through the drain port of the cultivation box 5, it flows through the drain pipe and into the interior of the lower-layer cultivation box 5. The water supply for the remaining cultivation boxes 5 is discharged from the drain port of the upper-layer cultivation box 5.

[0038] Furthermore, a main drain pipe 16 is connected to the drain port of the cultivation box 5 located at the bottommost layer of the cultivation module, and the drain port of the cultivation box 5 located at the bottommost layer of the cultivation module is connected to the water supply assembly through the main drain pipe 16, so that the excess liquid flowing out of the cultivation box 5 can flow back into the water tank 15 again, enabling the liquid to be recycled. The upper and lower layers of the cultivation boxes 5 are connected through the branch drain pipes 8, and the bottommost layer is connected to the water tank 15 through the main drain pipe 16, realizing the connection of the water circuit between the upper and lower layers and the water tank 15. The main water supply pipe 1 and the branch water supply pipe 6 are filled with drinking tap water added with fungicides or disinfectants, and a circulating water system is formed through the water tank 15, the main water supply pipe 1, the branch water supply pipe 6, the branch drain pipes 8, and the main drain pipe 16.

[0039] Furthermore, after the branch drain pipe 8 and the main drain pipe 16 extend into the cultivation box 5 through the drain port, the distance between the pipe orifice and the bottom end of the inner wall of the cultivation box 5 is 2 - 4 cm, which is used to control the water level in the cultivation box 5.

[0040] In this embodiment, a plurality of branch air supply pipes 7 are provided on the main air supply pipe 2, and each branch air supply pipe 7 extends into the interior of the cultivation box 5. Furthermore, an air supply pipe sinker 10 is fixedly connected to one end of the branch air supply pipe 7. The air supply pipe sinker 10 is made of a material with micropores, providing fresh air for the cultivation box 5 and increasing the air humidity in the box through the bubble evaporation effect.

[0041] Furthermore, filter pads are provided inside both the main air supply pipe 2 and the branch air supply pipes 7. The air inside the main air supply pipe 2 and the branch air supply pipes 7 is fresh air filtered by the filter pads. The filter pads are made of non-toxic chemical fiber cotton material with a thickness of 2 - 6 mm.

[0042] Furthermore, the branch water supply pipe 6, the branch air supply pipes 7, and the branch drain pipes 8 are all plastic hoses.

[0043] In this embodiment, a plurality of cultivation boxes 5 form a cultivation module, which is combined with the cultivation rack 3 to form a shelf cultivation system and placed in the cultivation room. By controlling the temperature of the cultivation room with an air conditioner, while creating the environmental conditions required for the growth of edible fungi, the facility cost investment is significantly reduced compared to the traditional standard mushroom-growing room.

[0044] In some possible embodiments, each cultivation module is connected to a water supply assembly and an air supply assembly. This setting can independently control the growth environment of the edible fungi in each cultivation module;

[0045] In some other possible embodiments, the water supply component and the air supply component supply water and air to multiple culture modules simultaneously to achieve the purpose of modular setting, reducing the input cost.

[0046] The above embodiments are only various possible implementation manners of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0047] In summary, when the device is in use, the mature cultivated edible mushroom bag 9 is opened at the mushroom outlet 12 and then placed in the culture box 5, and the branch water supply pipe 6 and the branch air supply pipe 7 are connected. Water enters the culture box 5 through the branch water supply pipe 6. After the water level reaches the height of the branch drain pipe 8 or the main drain pipe 16, it is discharged through the branch drain pipe 8 or the main drain pipe 16 and enters the next culture box 5 or the water tank 15. Air enters the culture box 5 through the water in the culture box 5 via the air supply pipe sink 10 at the port of the branch air supply pipe 7, continuously providing fresh air for the growth of the edible mushrooms. And when the air passes through the water through the air supply pipe sink 10, the evaporation of water is promoted under the action of the bubbles, providing a suitable humidity environment for the growth of the edible mushrooms. The relatively independent environment of the culture box 5 avoids the increase in the number of miscellaneous bacteria caused by human activities, reduces the probability of miscellaneous bacteria infection, and improves the cultivation success rate. The lamp belt on the culture rack 3 provides a suitable light environment for the growth of the edible mushrooms.

[0048] In the present application, the single culture device modules are combined to form a shelf-type three-dimensional culture facility. Different single culture devices are combined in series or in parallel through the main water supply pipe 1, the main drain pipe 16, and the main air supply pipe 2 to form a shelf-type three-dimensional culture facility. In the actual application process, according to needs, the main water supply pipe 1 and the air supply pipe can be switched on and off, and the position of the culture box 5 can be adjusted to realize the flexible placement of the culture box 5. In the traditional mushroom-growing room commonly used in production, the mushroom bags 9 are placed openly. There are large differences in humidity and carbon dioxide concentration between the upper and lower layers of the culture rack 3. If too many are placed, it is easy to cause too high a carbon dioxide concentration in the culture room, restricting the production capacity of a single culture room. The shelf-type three-dimensional culture facility makes full use of the space of the culture room, and adopts the design of continuously supplying water and air separately for the culture box 5 to ensure a suitable growth environment for the edible mushrooms, and greatly increases the placement density of the mushroom bags 9 in the culture room.

[0049] In the present application, the shelf-type three-dimensional culture facility is equipped with a water tank 15 and an air supply pump 14. Among them, the water in the water tank 15 is drinking tap water, and a bactericide or disinfectant is added according to needs. A circulating water system is formed through the water tank 15, the main water supply pipe 1, the branch water supply pipe 6, the branch drain pipe 8, and the main drain pipe 16. Fresh air filtered by a non-toxic chemical fiber cotton material with a thickness of 2-6 mm is adopted in the main air supply pipe 2 and the branch air supply pipe 7. While providing clean water and air for the culture box 5 through the water tank 15 and the air pump, the number of miscellaneous bacteria and the infection probability are reduced.

[0050] Traditional mushroom-growing rooms need to be equipped with purification fans, exhaust fans, refrigerators, humidifiers and other equipment in a renovated heat-insulated cultivation room. The construction cost for a 20-30 square-meter area is 50,000-100,000 yuan. During use, to reduce operating costs, it is necessary to minimize the number of times the cultivation room door is opened and closed manually, and minimize the ventilation frequency as much as possible while ensuring that the carbon dioxide concentration in the room does not exceed the standard. Despite this, due to equipment power limitations, not too many mushroom bags 9 can be placed in the cultivation room, thus restricting the production scale. This application forms a rack-type three-dimensional cultivation facility by combining single cultivation device modules. The main equipment inputs during production application include air conditioners, small-power water supply and gas supply equipment, plastic cultivation boxes 5, and lamp belts. The construction cost for a 20-30 square-meter area is only 30,000-40,000 yuan. The operating cost during production is mainly the electricity cost of the air conditioner, which is significantly reduced compared with traditional mushroom-growing rooms. The edible mushroom cultivation device provided by this application has low cost input and simple usage method, which is conducive to production application.
