Description

Technical Field

[0001] This invention relates to the field of Chinese medicinal herb cultivation technology, and in particular to a Chinese medicinal herb cultivation and seedling raising equipment. Background Technology

[0002] As the core stage of the growth cycle of Chinese medicinal herbs, the seedling stage is significantly influenced by light conditions, which have a decisive impact on the physiological metabolism, morphogenesis, and stress resistance of seedlings. Different types of Chinese medicinal herb seedlings have significantly specific requirements for light duration, intensity, and spectral distribution. Among them, special varieties such as ginseng, Panax notoginseng, and Angelica sinensis exhibit typical biological characteristics of "liking light but not tolerating strong light." These seedlings need 10-14 hours of sufficient light per day to ensure photosynthetic efficiency, but they are extremely sensitive to direct strong light. Excessive light can easily lead to leaf burn and transpiration imbalance, while insufficient light can cause problems such as excessive growth and decreased disease resistance. Therefore, precise control of the light environment is required.

[0003] In the current process of cultivating Chinese medicinal herbs, for the aforementioned plants that prefer light but are intolerant of strong light, traditional shading methods often rely on mechanical structures, such as mobile shade nets, when the light intensity is too strong. This method creates blind spots during shading and cannot dynamically adjust the shading intensity according to the seedling growth stage and real-time light intensity, easily leading to over- or under-shading. It also lacks light transmission and is difficult to adapt to the needs of seedlings at different stages. Furthermore, the mechanical shading structure has low control precision and slow response, failing to achieve a smooth transition of light intensity. In addition, existing seedling equipment supplemental lighting devices are mostly fixed light sources, creating blind spots and failing to cover the entire seedling rack area. Moreover, the light is not optimized, easily resulting in concentrated light spots or insufficient scattering, affecting photosynthetic efficiency.

[0004] Therefore, developing a Chinese medicinal herb cultivation and seedling raising equipment that can achieve adaptive light intensity control, uniform supplemental lighting, precise shading, and flexible light control capabilities has become the key to solving the current challenges in seedling light management. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide a seedling cultivation device for Chinese medicinal herbs. By setting up an elastic transparent sealed bag inside a transparent laminated glass, and using a light-adjusting component in conjunction with the sealed area formed by the glass top frame and the glass plate, it can achieve adaptive control of light intensity and precise shading. In the absence of light or low light environment, the built-in light source in the conical glass cover on the top frame can be used to achieve uniform supplemental lighting, which is adapted to the light requirements of Chinese medicinal herb seedlings. This solves the problems of existing shading methods, such as dead corners, inability to dynamically adapt to changes in light intensity, uneven supplemental lighting, unoptimized light, low precision of shading control, and lack of flexible management.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, a transparent laminated glass is installed at the slide rail of the seedling rack. The elastic transparent sealed bag on the transparent loading plate inside is made of a heat-responsive shape memory polymer film and filled with ethanol. When the external light intensity is strong, the ethanol expands due to heat, causing the sealed bag to form a convex lens, which disperses the light and weakens the light intensity. When the light intensity decreases, the sealed bag returns to its original shape, realizing real-time adaptive adjustment of light intensity, eliminating blind spots, solving the problem of excessive or insufficient shading, and achieving the effect of smooth light intensity transition and precise matching of seedling needs.

[0019] In the above scheme, the triangular base frame is connected to the annular top frame through a cylinder, and the conical glass cover on the top frame is composed of multiple Fresnel lenses. At the same time, the cylinder can drive the conical glass cover to move freely. Combined with the optimization effect of the Fresnel lenses on light, the supplementary light is parallel and evenly covers the entire area of ​​the seedling rack, eliminating the light dead angles caused by fixed light sources, improving photosynthetic efficiency, and meeting the seedlings' needs for light duration and uniformity.

[0020] In the above scheme, a transparent colloid is generated by the light-correcting component and injected into the glass top frame. The transparent body can weaken the light intensity and make the light evenly projected. When it is necessary to strengthen the shading, a dilute sodium hydroxide solution is injected through the valved feed pipe. The solution is stirred by the magnetic plate and the stirring rope to precipitate a white precipitate, so as to achieve precise control of the shading intensity. At the same time, with the dynamic adjustment of the elastic sealing bag, it can accurately adapt to the light requirements of seedlings at different growth stages and avoid excessive or insufficient shading.

[0046] The following is a detailed description of a medicinal herb cultivation and seedling raising device and its testing method provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some well-known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0047] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0048] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0049] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0050] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0051] like Figures 1 to 4 As shown, an embodiment of the present invention provides a medicinal herb planting and seedling raising device and its testing method, including a seedling rack 100. Multiple sets of cultivation fields 110 are evenly laid at the bottom of the seedling rack 100, which can cultivate medicinal herb seedlings. Slide rails 120 are provided on both sides of the four ends of the seedling rack 100. Transparent laminated glass 121 is slidably connected to the inner walls of two opposing sets of slide rails 120, and the slide rails 120 can clamp the transparent laminated glass 121. Multiple sets of transparent loading plates 122 are evenly fixedly installed on the inner walls of both sides of the transparent laminated glass 121. Multiple sets of elastic transparent sealing bags 124 are evenly arranged on the inner wall of the transparent loading plate 122. Each elastic transparent sealing bag 124 is made of a transparent thermally responsive shape memory polymer film. By controlling the material of the thermally responsive shape memory polymer, its deformation temperature can be changed to be close to the boiling point of ethanol. Combined with the thermal expansion and contraction effect of ethanol, a convex lens can be quickly formed. The wall of the elastic transparent sealing bag 124 is in contact with the inner wall of the transparent loading plate 122, allowing the transparent loading plate 122 to support the elastic transparent sealing bags 124, thus ensuring the elastic transparent sealing bags 124... 24 When deformation occurs, its sidewalls are supported to ensure that it forms a convex lens. The elastic transparent sealed bag 124 is filled with ethanol liquid. The upper and lower parts of the transparent loading plate 122 are provided with cables 123. The two ends of the cables 123 are fixedly connected to the inner wall of the transparent laminated glass 121. The top and bottom of the elastic transparent sealed bag 124 are fixedly connected to the corresponding cables 123. The cables 123 can shape the elastic transparent sealed bag 124 to help it form a convex lens. Multiple sets of elastic transparent sealed bags 124 are evenly spread inside the transparent laminated glass 121. In this invention, when the external light intensity is strong, the light can irradiate the elastic transparent sealing bag 124 inside the transparent interlayer glass 121, causing the temperature of the ethanol solution inside the elastic transparent sealing bag 124 to rise. Based on the thermal expansion and contraction effect, the ethanol will squeeze the elastic transparent sealing bag 124 to form a convex lens. The convex lens will disperse the sunlight, weaken its intensity, and evenly irradiate the plant seedling. When the external light intensity decreases, the elastic transparent sealing bag 124 will return to its original shape, thereby keeping the light intensity received by the seedling roughly unchanged.

[0052] like Figure 5 and Figure 6As shown, a triangular base frame 130 is fixedly installed at the center of the bottom of the seedling rack 100. Multiple groups of cultivation fields 110 are evenly and symmetrically distributed around the triangular base frame 130. Two sets of cylinders 131 are rotatably connected to the top corners of the outer side of the triangular base frame 130. The top of the multiple sets of cylinders 131 is rotatably connected to the same annular top frame 132. A conical glass cover 133 is fixedly installed on the inner wall of the middle part of the annular top frame 132. A light source is provided inside the conical glass cover 133. The conical glass cover 133 is composed of multiple Fresnel lenses. In this invention, when the external light intensity is low or the seedlings do not receive sufficient light for a long time, by lighting the light source inside the conical glass cover 133, the light emitted by the light source can shine parallel to the seedlings under the action of the Fresnel lenses, thereby increasing the light range and enabling the seedlings to absorb light evenly. At the same time, by controlling the cylinders 131, the conical glass cover 133 can move freely, thereby ensuring that there are no dead angles in the light.

[0053] like Figure 7 As shown, a glass top frame 200 is fixedly installed on the top of the seedling rack 100. Glass plates 210 are sealed and snapped onto the inner walls of the top and bottom surfaces of the glass top frame 200. A sealed area is formed between the glass plates 210, the glass top frame 200, the seedling rack 100, and the transparent laminated glass 121. The environment within this sealed area is suitable for the growth of seedlings. A sealed area is formed between the glass top frame 200 and the two sets of glass plates 210.

[0054] like Figures 8 to 12As shown, multiple sets of outer sliding grooves 222 are formed on both outer walls of the glass top frame 200. The outer sliding grooves 222 are rectangularly distributed on the side walls of the glass top frame 200. Multiple sets of inner sliding grooves 223 are formed on both inner walls of the glass top frame 200, and the inner sliding grooves 223 correspond one-to-one with the outer sliding grooves 222. A magnetic plate 224 is slidably connected to the inner wall of the outer sliding groove 222, and a magnetic plate 225 is slidably connected to the inner wall of the inner sliding groove 223. The magnetic plate 224 and the corresponding magnetic plate 225 are magnetically engaged. When the magnetic plate 224 moves, it can drive the stirring rope 240 to move under the action of magnetic force. The middle of both sides of the glass top frame 200 Each glass top frame 200 has a gear mounting area 221. Gears 230 are rotatably connected to the top and bottom inner walls of each gear mounting area 221. Two sets of magnetic plates 224 on the same plane have the same rack 231 fixedly mounted on their outer walls. The rack 231 meshes with the corresponding gear 230. Two sets of opposing magnetic plates 225 inside the glass top frame 200 have the same stirring rope 240 fixedly mounted on their inner walls. Outer frames 220 are fixedly mounted on both sides of the outer walls of the glass top frame 200. Motors 232 are fixedly mounted on both sides of the middle section of the outer frame 220, and the output end of each motor 232 is fixedly connected to the corresponding gear 230. The motors are driven... Motor 232 drives gear 230 to mesh with rack 231 via its output shaft, enabling rack 231 to move. Under the action of magnetic force, magnetic plates 224 at both ends of rack 231 drive magnetic plates 225 to move, thereby driving the corresponding stirring rope 240 to move and stir the liquid inside the glass top frame 200. Valve-equipped feed pipes 250 and valve-equipped discharge pipes 251 are respectively installed at the middle of both ends of the glass top frame 200. The valve-equipped feed pipes 250 can be used to introduce dilute sodium hydroxide solution into the colloid inside the glass top frame 200, thereby disrupting the colloid's equilibrium and causing it to precipitate, thus blocking light. The system blocks light and simultaneously discharges liquid and precipitates from the glass top frame 200 through the valved discharge pipe 251, facilitating light management. In this invention, when the seedlings do not require high-intensity light or require no light at all, a dilute sodium hydroxide solution (0.1-1 mol / L) is injected into the colloid in this section through the valved feed pipe 250. At the same time, multiple motors 232 are driven to move the stirring rope 240, thereby stirring the solution in this section until the pH rises to 8-10. At this point, the solution changes from transparent to white turbidity, and finally SiO2 precipitate is formed, which can block light and protect the seedlings.

[0055] like Figures 13 to 21As shown, a light-adjusting assembly 300 is provided on the outer end wall of the seedling rack 100. The light-adjusting assembly 300 includes a cylindrical reactor 310, which is fixedly connected to the seedling rack 100. A feeding port 311 and a feeding port 312 are provided on the side wall of the cylindrical reactor 310. Raw materials for generating a transparent colloid can be added into the cylindrical reactor 310 through the feeding port 311 and the feeding port 312. A jacket 313 is provided at the top of the cylindrical reactor 310. A stirring drum 314 is rotatably connected to the inner wall of the middle part of the cylindrical reactor 310. A driven wheel 315 is fixedly installed on the outer wall of the top of the stirring drum 314, and the driven wheel 315 is located within the jacket 313. The inner wall of the jacket 313 is rotatably connected to... A drive wheel 316 is provided, and the drive wheel 316 meshes with the driven wheel 315. A servo motor 318 is controlled to drive the drive wheel 316 to rotate, causing the drive wheel 316 to mesh with the driven wheel 315, thereby driving the stirring drum 314 to rotate and thus stirring the solution inside the cylindrical reactor 310. A servo motor 317 and a servo motor 318 are fixedly installed on the top of the cylindrical reactor 310. An inner cylinder 320 is rotatably connected to the inner wall of the stirring drum 314. Multiple sets of through grooves 319 are evenly distributed on the circumferential wall of the stirring drum 314, and multiple sets of through grooves 322 are evenly distributed on the circumferential wall of the inner cylinder 320, with each through groove 322 corresponding to one of the through grooves 319. A drip column 321 is fixedly installed on the inner wall of the inner cylinder 320. The drip column 321 and the bottom of the inner cylinder 320 form a small-diameter annular drip groove 323. The drip column 321 can be rotated by driving the servo motor 317, thereby rotating the inner cylinder 320. This changes the overlapping area of ​​the second channel 322 and the first channel 319, thus controlling the drip rate of dilute hydrochloric acid. An annular sealing cylinder 340 is fixedly connected to the outer wall of the middle part of the stirring cylinder 314, and the first channel 319 is located inside the annular sealing cylinder 340. A guide pipe 341 is fixedly installed on the top outer wall of the annular sealing cylinder 340. A plug 342 is snapped into the top inner wall of the guide pipe 341. The plug 342 can prevent dilute hydrochloric acid from splashing. The evaporation process involves the output terminals of servo motors 317 and 318 being fixedly connected to the top of the drip column 321 and the drive wheel 316, respectively. In this invention, when the seedlings are small and the external light intensity is high, ethanol and methyl orthosilicate (TMOS) are added to the cylindrical reactor 310 through feed ports 311 and 312, with the addition ratio controlled at 20:1. Simultaneously, servo motors 317 and 318 are driven synchronously, enabling the stirring drum 314 and the drip column 321 to rotate synchronously. At this time, the stirring drum 314 can stir the ethanol and methyl orthosilicate in the cylindrical reactor 310. During the stirring process, 0.A 1 mol / L dilute hydrochloric acid solution is introduced into the inner cylinder 320 through channels 319 and 322. Under centrifugal force, the solution drips into the cylindrical reactor 310 through the annular dripping groove 323 at the bottom of the inner cylinder 320. The dripping rate can be controlled by adjusting the overlap area of ​​channels 319 and 322. The total amount of dilute hydrochloric acid dripped into the cylindrical reactor 310 is also controlled to be the same as that of methyl orthosilicate. The pH of the liquid in the cylindrical reactor 310 is 3-4. After stirring at room temperature for 15-20 minutes, the solution in the cylindrical reactor 310 gradually changes from clear to a colorless, transparent colloid. The principle of this reaction is the hydrolysis of silicate ester to generate nano-SiO2 particles: Si(OCH3)4 + 4H2O → SiO2 (colloid) + 4CH3OH.

[0056] like Figure 1 and Figure 13 As shown, a glue pump 350 is fixedly installed at the bottom output port of the cylindrical reactor 310. A three-way pipe 360 ​​is fixedly installed at the output end of the glue pump 350. Solenoid valves 361 are fixedly installed at both ends of the three-way pipe 360. A glue guide pipe 362 is fixedly installed at the output end of the solenoid valve 361, and the other end of the glue guide pipe 362 is connected to the inside of the glass top frame 200. In this invention, when a colorless and transparent colloid is formed inside the cylindrical reactor 310, the low-shear force glue pump 350 (diaphragm pump, peristaltic pump) and the solenoid valve 361 are used to generate a colloid. 61. The colorless and transparent colloid formed in the cylindrical reactor 310 is transported through the colloid guide tube 362 to the sealed area formed by the glass top frame 200 and the glass plate 210. At this time, the colloid in the area can weaken the light intensity and make the light shine on the seedlings in the cultivation field 110 in a parallel and uniform manner. During the transportation of the colloid, a low-shear colloid pump 350 with rubber material compatibility should be selected. At the same time, the flow rate and pressure should be controlled to be stable, avoid violent disturbances, and ensure that the pump body is clean and free of residual electrolytes or impurities.

[0057] The working principle of the technical solution provided by the present invention is as follows: When cultivating light-loving medicinal seedlings, the seedlings are transplanted into the cultivation field 110, and the transparent laminated glass 121, the glass top frame 200 and the glass plate 210 are installed on the seedling rack 100 so that the equipment is under light, so that the medicinal materials inside the seedling rack 100 are in an environment suitable for growth.

[0058] When the seedlings are small and the external light intensity is high, ethanol and methyl orthosilicate (TMOS) are added into the cylindrical reactor 310 through feed inlet 311 and feed inlet 312, with the addition ratio controlled at 20:1. Simultaneously, servo motors 317 and 318 are driven synchronously to ensure that the stirring drum 314 and the drip column 321 rotate synchronously. At this time, the stirring drum 314 can stir the ethanol and methyl orthosilicate in the cylindrical reactor 310. During the stirring process, the ethanol is fed into the surrounding area through the feed pipe 341. 0.1 mol / L dilute hydrochloric acid is injected into the sealed cylinder 340. The dilute hydrochloric acid can then enter the inner cylinder 320 through channels 319 and 322. Under centrifugal force, it drips from the annular drip groove 323 at the bottom of the inner cylinder 320 into the cylindrical reactor 310. The dripping rate can be controlled by adjusting the overlap area of ​​channels 319 and 322. Simultaneously, the total amount of dilute hydrochloric acid dripped into the cylindrical reactor 310 is controlled to be the same as that of methyl orthosilicate. Furthermore, the cylindrical reactor 310... The pH of the liquid inside is 3-4. After stirring at room temperature for 15-20 minutes, the solution in the columnar reactor 310 gradually changes from clear to a colorless and transparent colloid. Then, using a low-shear force gel pump 350 (diaphragm pump, peristaltic pump) and a solenoid valve 361, the colorless and transparent colloid formed in the columnar reactor 310 is transported through a gel guide tube 362 to the sealed area formed by the glass top frame 200 and the glass plate 210. At this point, the colloid in this area can weaken the light intensity, while simultaneously making the light illumination parallel and uniform. When the seedlings in the cultivation field 110 are exposed to light, and the seedlings do not require high intensity light or light, a dilute sodium hydroxide solution (0.1-1 mol / L) is injected into the colloid in this area through the valved feed pipe 250. At the same time, multiple sets of motors 232 are driven to drive the stirring rope 240 to move, thereby stirring the solution in this area. The stirring continues until the pH rises to 8-10. At this time, the solution changes from transparent to white turbidity, and finally SiO2 precipitates out, which can block the light and protect the seedlings.

[0059] Meanwhile, when the external light intensity is strong, the light can irradiate the elastic transparent sealing bag 124 inside the transparent laminated glass 121, causing the temperature of the ethanol solution inside the elastic transparent sealing bag 124 to rise. Based on the thermal expansion and contraction effect, the ethanol will squeeze the elastic transparent sealing bag 124 to form a convex lens. The convex lens will disperse the sunlight, weaken its intensity, and evenly irradiate the plant seedlings. When the external light intensity decreases, the elastic transparent sealing bag 124 will return to its original shape, thereby keeping the light intensity received by the seedlings roughly unchanged.

[0060] When the ambient light intensity is low or the seedlings do not receive sufficient light, the light source inside the conical glass cover 133 is lit. Under the action of the Fresnel lens, the light emitted by the light source can shine on the seedlings in parallel, thereby increasing the light range and allowing the seedlings to absorb light evenly. At the same time, the conical glass cover 133 can be moved freely by controlling the cylinder 131, thereby ensuring that there are no blind spots in the light.
