Description

Technical Field

[0001] This utility model relates to the field of fern propagation technology, specifically a constant temperature and light germination culture device for fern spores. Background Technology

[0002] In the field of fern propagation technology, fern spore germination is a key step in propagation. To meet the light and constant temperature conditions required for fern spore germination, a constant temperature chamber is often used as the culture environment. It provides continuous light through a built-in light source and maintains a constant temperature to promote spore germination.

[0003] During the germination of fern spores, it is necessary to regularly observe the germination status (such as key stages like spore imbibition and germination tube formation) to assess the culture effect. The current conventional observation method is to open the door of the incubator, remove the culture tray from the incubator, and observe it from outside. This operation has significant drawbacks: First, opening the door will disrupt the stable thermal field and environment inside the incubator, allowing a large amount of ambient air from outside to rush in, causing drastic fluctuations and sudden drops in the culture temperature inside the incubator. Second, after the observation is completed and the door is closed again, the incubator system needs to consume additional time and energy to restore the temperature inside the incubator to the set culture temperature. The temperature shock generated in this process breaks the continuous constant temperature environment required for fern spore germination, which has a significant impact on fern spore germination.

[0004] Therefore, this invention proposes a constant temperature and light germination culture device for fern spores to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a constant temperature and light germination culture device for fern spores to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A constant-temperature, light-based fern spore germination culture device includes an incubator and a first temperature control component for maintaining a set temperature inside the incubator. The incubator contains several support plates arranged from top to bottom to support culture trays. Each support plate has a corresponding passageway on one side, and each passageway has an openable cover. A light-emitting component is also located above the support plates. The germination culture device further includes an observation box located on the side of the incubator with the passageways, a first moving component corresponding to each support plate to drive the support plate out of the incubator through the corresponding passageway, a second moving component for driving the observation box to move up and down, and a second temperature control component for ensuring that the temperature inside the observation box is the same as the temperature inside the incubator. The upper side of the observation box is transparent, and the side of the observation box facing the incubator is open and in contact with the incubator wall.

[0007] In one alternative: the first moving component includes a first lead screw, a plurality of guide rods, and a first driving member for driving the first lead screw to rotate, wherein the first lead screw is threadedly engaged with a bearing plate, and the guide rods are slidably engaged with the bearing plate.

[0008] In one alternative: the observation box has an adhesive strip along its open side edge.

[0009] In one alternative: the lighting assembly includes a crossbeam, a mounting base on the crossbeam, and a light source on the mounting base.

[0010] In one alternative: a telescopic component is also provided between the crossbeam and the mounting base to adjust the illumination height of the lighting lamp.

[0011] In one alternative: the support plate is provided with several limiting frames adapted to the size of the culture tray.

[0012] In one alternative: the second moving component includes two second lead screws mounted on the incubator, and the observation box has bosses on both sides. The two second lead screws pass through the two bosses respectively in a threaded connection. A belt drive structure is provided between the two second lead screws. The second moving component also includes a second driving member for driving the two second lead screws to rotate.

[0013] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: When it is necessary to observe the germination status of spores in the culture tray, the second moving component first moves the observation box to the height of the target support plate, and the second temperature control component makes the temperature inside the observation box the same as the temperature inside the culture box. Then, the cover plate on the corresponding passage slot is opened, and the corresponding first moving component is activated to move the target support plate out of the culture box and into the observation box, that is, the corresponding culture tray moves into the observation box. The germination status of spores in the culture tray is observed from the top of the observation box. The observation is carried out in a closed space to avoid temperature fluctuations and thus avoid affecting the germination of fern spores.

Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Please see Figures 1-3A constant-temperature, light-based fern spore germination culture device includes an incubator 2 and a first temperature control component 7 for maintaining a set temperature inside the incubator 2. The incubator 2 has several support plates 3 arranged from top to bottom for supporting culture trays. Each support plate 3 has a corresponding passageway 10 on one side, and a cover plate 11 is provided at each passageway 10 (the cover plate 11 can be opened and closed by a motor-driven flipping mechanism or by a linear motor-driven translation mechanism; this application does not limit this). Above the support plates 3... The device also includes a light-emitting component 5. The germination culture device further includes an observation box 6 located on the side of the culture box 2 with the passage slot 10, a first moving component 4 corresponding to the support plate 3 to drive the support plate 3 to move out of the culture box 2 through the corresponding passage slot 10, a second moving component 9 for driving the observation box 6 to move up and down, and a second temperature control component 8 for making the internal temperature of the observation box 6 the same as the internal temperature of the culture box 2. The upper side of the observation box 6 is transparent, and the side of the observation box 6 facing the culture box 2 is open and in contact with the wall of the culture box 2.

[0024] It should be noted that the first temperature control component 7 and the second temperature control component 8 have the same structure, including a temperature sensing module (such as a multi-point distributed temperature sensor array), a heating module, a cooling module, and a control module, etc., which are existing technologies. The specific components of each module and the connection and linkage between the components will not be described in detail here. The germination culture device also includes a ventilation component (not shown in the figure), which is used to maintain a suitable gas environment inside the culture box 2 to meet the requirements of fern spore germination culture. The ventilation component includes a circulating fan, air duct and guide plate, and air intake and exhaust system, etc., which are also existing technologies and will not be described in detail here. In addition, the outside of the culture box 2 is provided with a control panel for operating the germination culture device.

[0025] The culture tray inoculated with fern spores is placed on the support plate 3. The first temperature control component 7 keeps the inside of the incubator 2 at a set temperature, i.e., in a constant temperature state. The light component 5 provides light to carry out the constant temperature and light germination culture of fern spores. When it is necessary to observe the germination status of the spores in the culture tray, the second moving component 9 first moves the observation box 6 to the height of the target support plate 3, and the second temperature control component 8 makes the temperature inside the observation box 6 the same as the temperature inside the incubator 2. Then, the cover plate 11 on the corresponding passage slot 10 is opened, and the corresponding first moving component 4 is activated to move the target support plate 3 out of the incubator 2 and into the observation box 6. That is, the corresponding culture tray moves into the observation box 6. The germination status of the spores in the culture tray is observed from the top of the observation box 6. The observation is carried out in a closed space to avoid temperature fluctuations and thus avoid affecting the germination of fern spores.

[0026] Furthermore, the observation box 6 has an adhesive strip 12 along its open side edge. By setting the adhesive strip 12, there is no gap between the open side of the observation box 6 and the box wall, thereby reducing the influence of external temperature.

[0027] Please see Figure 1 and Figure 4 In one embodiment of this utility model, the first moving component 4 includes a first lead screw 402, a plurality of guide rods 403, and a first driving member 401 for driving the first lead screw 402 to rotate (the first driving member 401 is a servo motor, geared motor, etc. in the prior art). The first lead screw 402 is threadedly engaged with the support plate 3, and the guide rods 403 are slidably engaged with the support plate 3. The first driving member 401 drives the first lead screw 402 to rotate, thereby driving the support plate 3 to move out of the incubator 2 and perform a resetting action. The first lead screw 402 and the plurality of guide rods 403 also provide support for the support plate 31.

[0028] Furthermore, in this embodiment, the support plate 3 is provided with several limiting frames 13 adapted to the specifications of the culture tray. The culture tray usually has certain specifications. This embodiment is designed for culture trays of specific specifications. The limiting frames 13 limit the culture tray to prevent the culture tray from moving or shifting when the support plate 3 moves.

[0029] Please see Figure 1 and Figure 5 In one embodiment of this utility model, the lighting component 5 includes a crossbeam 501, a mounting base 502 disposed on the crossbeam 501, and a light lamp 503 disposed on the mounting base 502. The light intensity of the light lamp 503 is adjustable. A telescopic component 504 (such as an electric telescopic rod or telescopic cylinder in the prior art) is also provided between the crossbeam 501 and the mounting base 502 to adjust the light height of the light lamp 503 (during the germination and cultivation of ferns, the distance between the light lamp 503 and the seedling needs to be adjusted according to their different growth and development stages in order to achieve precise control of the light intensity).

[0030] Please see Figure 1 and Figure 2In one embodiment of this utility model, the second moving component 9 includes two second lead screws 901 mounted on the incubator 2. The observation box 6 has protrusions 904 on both sides. The two second lead screws 901 pass through the two protrusions 904 respectively in a threaded connection. A belt drive structure 902 is provided between the two second lead screws 901 (that is, both second lead screws 901 are provided with pulleys, and a belt is wound between the two pulleys to realize transmission). The second moving component 9 also includes a second driving member 903 for driving the two second lead screws 901 to rotate (the second driving member 903 is a servo motor, geared motor, etc. in the prior art). The two second lead screws 901 are driven to rotate synchronously by the second driving member 903, thereby driving the observation box 6 to rise and fall.

[0031] Furthermore, in this embodiment, the incubator 2 is also symmetrically provided with several slide rails running from top to bottom (not shown in the figure), and the observation box 6 is provided with a boss that slides and is engaged in the slide rail (not shown in the figure). The boss and the slide rail slide together to play a guiding role and improve the lifting stability of the observation box 6.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
