Description

Technical Field

[0001] This utility model relates to the field of Cordyceps militaris cultivation technology, specifically to a Cordyceps militaris cultivation device. Background Technology

[0002] Cordyceps militaris, also known as North Cordyceps, is a fungus with important medicinal and edible value. Its artificial cultivation process typically includes inoculation, mycelial culture, fruiting body management, and harvesting. Different stages have different environmental requirements: During the mycelial culture stage, Cordyceps militaris mycelium needs to grow and spread on a nutrient substrate, which usually requires a relatively closed, humid, dark, and low-oxygen environment to reduce contamination by other fungi and promote mycelial growth. During the fruiting body management stage, i.e., the formation and growth stage of the fruiting body (commonly known as "grass"), suitable light stimulation, good ventilation to replenish oxygen and expel carbon dioxide produced by metabolism, and maintaining humidity are necessary. If too much carbon dioxide accumulates, it will inhibit the normal growth and development of the fruiting body.

[0003] Existing cultivation methods mostly use culture bottles or simple culture boxes, which make it difficult to meet the conflicting needs of sealing and ventilation at different stages. For example, in order to meet the sealing requirements during the mycelial stage, the containers are often well-sealed, but during the emergence stage, additional operations (such as changing the lid or punching holes) are required to achieve ventilation, which increases the complexity of operations and the risk of contamination. In addition, traditional culture containers require tools to be inserted into the bottle during harvesting, which can easily cause epidermal damage or breakage to the Cordyceps militaris fruiting bodies. Subsequent cleaning, grading and other steps are also more cumbersome, increasing labor and time costs.

[0004] Therefore, a new Cordyceps militaris cultivation device needs to be designed to facilitate the adjustment of the cultivation environment to meet the needs of different growth stages and to facilitate harvesting. Utility Model Content

[0005] In order to overcome the problems in the background art, this utility model provides a Cordyceps militaris cultivation device, which solves the problems in the prior art that the Cordyceps militaris cultivation container is difficult to meet the sealing requirements of the mycelial culture stage and the ventilation requirements of the grass emergence management stage, as well as the difficulties in harvesting and the easy damage to the Cordyceps militaris fruiting bodies.

[0006] A Cordyceps militaris cultivation device includes a cultivation base, an inner cylinder, an outer cylinder, and a light shield. The cultivation base includes a mesh-like side wall and a bottom wall. Limiting blocks are evenly spaced on the bottom wall of the cultivation base. The bottom of the inner cylinder has a positioning structure that cooperates with the limiting blocks. The inner cylinder is positioned inside the cultivation base. The inner cylinder wall has a harvesting window and an upper and lower ventilation port. The outer cylinder is sleeved outside the inner cylinder and can rotate relative to the inner cylinder. The outer cylinder has corresponding upper and lower ventilation openings at the positions of the upper and lower ventilation ports of the inner cylinder. The light shield is detachably installed on the top of the base.

[0007] Furthermore, the bottom wall mesh structure of the culture base is integrally formed with upwardly raised and longitudinally and transversely arranged airflow channels.

[0008] Furthermore, the culture base is provided with a suspension structure.

[0009] Furthermore, the cross-section of the culture base is a trapezoidal structure that is wider at the top and narrower at the bottom.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model allows for easy alignment or misalignment of the corresponding ventilation openings of the inner and outer cylinders through relative rotation, thereby quickly switching between the sealed and ventilated states of the cultivation container. This satisfies the conflicting gas environment requirements of Cordyceps militaris at different growth stages, making operation simple and convenient. The inner cylinder is equipped with a harvesting window, and the outer cylinder can be easily removed. During harvesting, the operator can easily access and harvest the fruiting bodies of Cordyceps militaris through the harvesting window. Compared with traditional culture bottles, this reduces the difficulty of harvesting, minimizes damage and breakage to the fruiting bodies, and thus improves the product's marketability and value.

[0011] 2. The cultivation base of this utility model adopts a mesh plate structure and is equipped with an upward-raised airflow channel to facilitate air circulation at the bottom. The suspension structure and trapezoidal cross-section structure provide flexible placement and lighting methods, which facilitates space utilization and management. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0016] See Figure 1-3 This utility model proposes a Cordyceps militaris cultivation device, including a cultivation base 1, an inner cylinder 2, an outer cylinder 3, and a light shield 4. The cultivation base 1 is used to support and position the cultivation container. The side walls and bottom walls of the cultivation base 1 preferably adopt a mesh plate structure to facilitate air circulation. Multiple limiting blocks 12 are provided on the bottom wall of the cultivation base 1. These limiting blocks 12 are evenly spaced and used to cooperate with the bottom of the inner cylinder 2. The inner cylinder 2 is used to contain the culture medium and Cordyceps militaris inoculum. The inner cylinder 2 is placed on the cultivation base 1. Its bottom is provided with a positioning structure that cooperates with the upper limiting blocks 12 of the cultivation base 1, such as a groove or a bottom edge of a specific shape, so that the inner cylinder 2 can be stably placed on the base 1 and will not easily rotate during subsequent operations. At least one large harvesting window 21 is opened on the cylinder wall of the inner cylinder 2 to facilitate harvesting operations. At the same time, an upper vent 22 is opened on the upper part or top of the cylinder wall, and a lower vent 23 is opened on the lower part of the cylinder wall.

[0017] The outer cylinder 3 is a hollow cylindrical structure with an inner diameter slightly larger than the outer diameter of the inner cylinder 2. It is fitted onto the outside of the inner cylinder 2 and can rotate freely outside the inner cylinder 2. On the cylinder wall or top cover structure of the outer cylinder 3, there is a corresponding upper ventilation opening 31 at the position corresponding to the upper vent 22 of the inner cylinder 2, and a corresponding lower ventilation opening 32 at the position corresponding to the lower vent 23 of the inner cylinder 2.

[0018] During the mycelial culture stage, when a sealed environment is required, the operator can rotate the outer cylinder 3 to offset the upper ventilation opening 31 and lower ventilation opening 32 of the outer cylinder 3 from the upper ventilation port 22 and lower ventilation port 23 of the inner cylinder 2. At this time, the inside of the culture container is basically sealed, which is conducive to mycelial growth and prevents contamination by other microorganisms. Since the inner cylinder 2 is positioned by the limiting block 12 of the base 1, the inner cylinder 2 will not rotate when the outer cylinder 3 is rotated, making the operation convenient. During the fruiting management stage, when ventilation is required, the operator rotates the outer cylinder 3 again to align the upper ventilation opening 31 of the outer cylinder 3 with the upper vent 22 of the inner cylinder 2, and at the same time align the lower ventilation opening 32 of the outer cylinder 3 with the lower vent 23 of the inner cylinder 2. At this time, air can circulate through the aligned openings. The upper opening facilitates the replenishment of fresh air (oxygen), while the lower opening facilitates the discharge of the heavier carbon dioxide produced by the respiration of Cordyceps militaris, thus providing a good gaseous environment for the growth of the fruiting bodies.

[0019] The device also includes a light shield 4, the shape and size of which match the culture base 1 or the array of culture containers on it. The light shield 4 can be conveniently placed on top of the culture base 1 or the support. During the mycelial culture stage, the light shield 4 can provide the necessary light-blocking conditions. When light is needed during the grass emergence management stage, the light shield 4 can be removed.

[0020] The bottom wall mesh structure of the cultivation base 1 can be integrally formed with upwardly raised crisscrossing airflow channels 11. These raised airflow channels 11 ensure good air circulation at the bottom of the inner cylinder on the one hand, and also serve to separate the inner cylinder 2 on the other hand. A suspension structure 13 can be installed on the culture base 1, such as a hanging ring or a hanging rod, so that the entire culture base and the culture container on it can be suspended and placed, which is convenient for multi-layer three-dimensional culture or installation and management in specific environments.

[0021] The overall cross-section of the culture base 1 can be designed as a trapezoidal structure that is wider at the top and narrower at the bottom, which helps to improve the lighting conditions of the edge containers.

[0022] Work process: Before inoculation, the inner cylinder 2, outer cylinder 3, and culture base 1 are cleaned and disinfected. The sterilized culture medium is put into the inner cylinder 2 and Cordyceps militaris inoculation is carried out. Then the inner cylinder 2 is placed on the culture base 1, ensuring that its bottom fits properly with the limiting block 12. Put on the outer cylinder 3 and rotate it to a sealed state (the air vents and ventilation openings of the inner and outer cylinders are staggered), and cover it with a light shield (4); place the entire device or an array of multiple devices in a suitable temperature and humidity environment for mycelial culture. Once the mycelium has fully grown on the culture medium, the fruiting management stage begins. Remove the light shield 4 and rotate the outer cylinder 3 to the ventilation state (align the air vents and ventilation openings of the inner and outer cylinders). Provide appropriate light, temperature, and humidity as needed, and wait for the Cordyceps militaris fruiting bodies to grow and mature. During harvesting, carefully remove the outer cylinder 3. At this time, the harvesting window 21 on the inner cylinder 2 wall is fully exposed. The operator can easily harvest mature Cordyceps militaris fruiting bodies through the harvesting window 21, reducing damage. After harvesting, the inner cylinder 2 and the culture base 1 can be cleaned to prepare for the next round of culture.

[0023] 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 inventive concept of the present utility model, should be included within the protection scope of the present utility model.
