Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ecological restoration, and particularly relates to an intelligent seedling cultivation device for grassland degradation ecological restoration. BACKGROUND

[0002] Grassland degradation is a serious ecological challenge faced by the world, and the core of ecological restoration lies in quickly and massively cultivating high-quality and robust native grass seedlings. Traditional flat seedling cultivation mode has inherent defects such as large land occupation area, low unit yield and poor environmental controllability, and is difficult to meet the seedling demand of large-scale ecological restoration. To overcome the above problems, vertical agricultural technology, especially spiral pasture rapid propagation tower, emerges as the times require. Such equipment greatly improves the yield of seedlings per unit area through three-dimensional space layout, and provides the possibility for precise control of environmental factors. Light, as the energy source for plant photosynthesis, its management is a key link for the success or failure of seedling cultivation. In the existing light system of spiral pasture rapid propagation tower, the following technical bottlenecks generally exist: Interlayer light interference problem: due to the compact tower structure, the upper cultivation plate will form a light shield on the lower layer, resulting in insufficient light received (total light received) by the lower plants. Even if the tower body rotates as a whole, it is difficult to completely eliminate uneven light, resulting in poor uniformity and uneven quality of the cultivated seedlings. Low energy efficiency problem: in order to achieve uniform light, the existing technology mostly uses large-area continuous light supplement or complex follow-up lighting system, which consumes a lot of electric energy. A large amount of light energy is not effectively utilized by plants. During the irradiation process, part of the light source directly irradiates to the lower layer along the upper layer. There is a lot of invalid loss in the propagation process of the lighting light. Part of the light emitted by the light source directly penetrates the upper cultivation interval, irradiates to the non-target area of the lower layer or is absorbed by the tower structure. Not only causes serious waste of light energy, but also aggravates the heat load of the system. SUMMARY

[0017] The existing spiral forage propagation tower 1 has problems such as severe interlayer light interference, low energy efficiency, and poor reliability of electronic control system, resulting in uneven seedling growth and inconsistent quality, which seriously affects the grassland ecological restoration effect. To address this, a novel lighting control component based on pure mechanical transmission was designed. Through the coordinated operation of the power transmission component, the power control component, and the speed change structure 49, programmed intermittent lighting and spectral adjustment of the lamp tube 411 were achieved. This avoids the risk of failure of traditional electronic control systems due to harsh environments. The pure mechanical structure ensures the absolute reliability of lighting control, enabling each grass to receive uniform and suitable light, thereby improving light energy utilization and significantly enhancing seedling cultivation quality and ecological restoration efficiency.

[0018] When in use, when the device starts to run, the rotation of the driving wheel 2 is synchronously transmitted to the arc cover 45 and the power-on control assembly through the power transmission assembly, the cam 46 in the power-on control assembly periodically presses the micro switch 48 (the micro switch 48 adopts a waterproof and dustproof design) in the rotation process, the intermittent power-on of the lamp tube 411 is realized, at the same time, the cam 46 drives the light adjustment cover 410 to rotate through the variable speed structure 49, the rotation of the light adjustment cover 410 changes the light transmission characteristics, simulates the change of the sunlight spectrum, and after the set light period, each component is automatically reset under the driving of the transmission system, and the next lighting cycle is prepared.

[0019] Specifically, the driving wheel 2 is rotationally connected to the outer side and the inner side of the spiral forage fast propagation tower 1 at equal intervals, the mounting strip 3 is fixedly installed in the spiral forage fast propagation tower 1 at equal intervals, and the light control assembly is arranged in the mounting strip 3. The light control assembly comprises a power transmission assembly, an arc cover 45, a power-on control assembly, a variable speed structure 49, a light adjustment cover 410 and a lamp tube 411. The power transmission assembly comprises a guide wheel 41, a friction sleeve 42, a stand 43 and a transmission structure 44; the stand 43 is rotationally connected to the inside of the mounting strip 3 through a bearing, the end of the stand 43 close to the driving wheel 2 is provided with the guide wheel 41 through a key, the outer surface of the guide wheel 41 is provided with an annular groove in the middle, the friction sleeve 42 is installed on the outer surface of the guide wheel 41 at the position inside the annular groove through interference fit (the friction sleeve 42 is made of high-friction coefficient wear-resistant material to ensure the reliability of power transmission), the outer side of the friction sleeve 42 is in pressure contact with the outer side of the driving wheel 2 and synchronously rotates through friction, the end of the stand 43 away from the guide wheel 41 is provided with the transmission structure 44 through clamping, and the end of the transmission structure 44 away from the stand 43 is provided with the arc cover 45 through spline; The power-on control assembly comprises a cam 46, a fixed ring 47 and a micro switch 48; the cam 46 is clamped and installed at the end of the arc cover 45 away from the stand 43, the fixed ring 47 is fixedly installed in the mounting strip 3, the micro switch 48 is arranged in the fixed ring 47, the rotation point of the cam 46 is located at the center point of the fixed ring 47, the cam 46 periodically presses the micro switch 48 in the rotation process (the cam 46 presses the touch button of the micro switch 48 for a long time, so that the lamp tube 411 is powered on, and when the cam 46 is separated from the touch button of the micro switch 48, the lamp tube 411 is powered off), and the power-on and power-off of the lamp tube 411 are controlled; The end of the cam 46 away from the column 43 is provided with a speed change structure 49, and the end of the speed change structure 49 close to the column 43 is provided with a light adjusting cover 410. The light adjusting cover 410 is a cylindrical structure, and the inner surface is plated with a variable color filter film. The speed change structure 49 is driven at a lower speed than the cam 46 to rotate uniformly, so as to realize the continuous change of the color of the light. The inside of the mounting strip 3 is provided with a lamp tube 411. The lamp tube 411 is clamped and mounted in the inside of the mounting strip 3 and located in the central region of the light adjusting cover 410. The lamp tube 411 is an LED lamp tube and provides the light required for plant growth. The inside of the mounting strip 3 is provided with a positioning groove 413, and the lamp tube 411 is located in the inside of the positioning groove 413.

[0020] In order to realize the rotation of the arc-shaped cover 45 driven by the rotation of the column 43 in the above example, the following solution is provided, as shown in the figure. Figures 3 to 7 The transmission structure 44 is composed of two sprockets and a chain. The two sprockets are both in rotating connection with the mounting strip 3. One of the sprockets in the transmission structure 44 is clamped and mounted with the arc-shaped cover 45, and the other sprocket is connected with the column 43. In use, the rotation of the column 43 drives the transmission structure 44 to operate. At this time, the two sprockets in the transmission structure 44 are in synchronous rotation through the chain. Since one sprocket is connected with the arc-shaped cover 45 and the other sprocket is connected with the column 43, the rotation of the column 43 drives the arc-shaped cover 45 to rotate. At this time, the arc-shaped cover 45 changes the position of the light source outlet. Further, in order to reduce the emission of the light source and improve the utilization rate of the light source, the following solution is provided. The arc-shaped cover 45 is symmetrically bonded with an inclined plate 412 at both sides of the bottom end. The inner wall of the arc-shaped cover 45 and the inclined plate 412 is bonded with a light condensing sheet 414 (the light condensing sheet 414 is made of high reflectivity nanometer material to improve the light energy utilization efficiency) for reflecting and condensing light.

[0021] In order to realize the rotation of the arc-shaped cover 45 driven by the rotation of the arc-shaped cover 45 in the above example, the following solution is provided, as shown in the figure. Figures 6 to 8 The speed change structure 49 includes an inner sawtooth ring 491, a large gear 492, a small gear 493 and an outer gear ring 494. The inner sawtooth ring 491 is connected with the cam 46 in the electrified control assembly. The inner side of the inner sawtooth ring 491 is in meshing connection with the large gear 492, and the large gear 492 is in rotating connection with the mounting strip 3. The outer side of the large gear 492 is in pressing contact connection with the small gear 493, and the small gear 493 is in rotating connection with the mounting strip 3. The outer side of the small gear 493 is in pressing contact connection with the outer gear ring 494, and the outer gear ring 494 is in rotating connection with the mounting strip 3 and connected with the light adjusting cover 410 close to the column 43. The outer gear ring 494 is used to adjust the rotating speed of the light adjusting cover 410. The light adjusting cover 410 is in rotating connection with the mounting strip 3 and driven to rotate by the speed change structure 49. The light adjusting cover 410 is used to adjust the color of the light.

[0022] In use, the rotation of cam 46 drives the inner sawtooth ring 491 to rotate. When the inner sawtooth ring 491 rotates, it drives the large gear 492 to rotate. When the large gear 492 rotates, it drives the small gear 493 to rotate. When the small gear 493 rotates, it drives the outer gear ring 494 to rotate. When the outer gear ring 494 rotates, it drives the dimming cover 410 to rotate.

[0023] Working principle: When the spiral forage rapid propagation tower 1 starts running, the drive wheel 2 starts to rotate under the drive of the conveying system. At this time, the friction sleeve 42 starts to rotate under the drive of the drive wheel 2. The reliability of power transmission is ensured by the high friction coefficient wear-resistant material. The guide wheel 41 rotates synchronously through the friction sleeve 42, which drives the column 43 to start rotating. When the column 43 rotates, it drives the transmission structure 44 to run. The pure mechanical transmission ensures the synchronicity and stability of the system startup and avoids the startup failure of the electronic system due to voltage fluctuations. The column 43 drives one sprocket of the transmission structure 44 to rotate. One sprocket drives another sprocket to rotate synchronously through chain transmission. The other sprocket drives the arc-shaped cover 45 to start rotating. The arc-shaped cover 45 drives the cam 46 to enter the working state. The chain transmission system ensures precise synchronization of power transmission and improves transmission efficiency, which is significantly better than the traditional belt transmission method. When the cam 46 rotates to the position of the micro switch 48 at its highest point, the switch trigger arm is pressed continuously, the circuit is connected, and the lamp tube 411 starts to emit light. The light-concentrating sheet 414 in the arc-shaped cover 45 and the inclined plate 412 efficiently concentrates the light and guides it to the culture plate, preventing the light source from scattering and affecting the other culture plates. When the cam 46 rotates to the position of the micro switch 48 at its lowest point, the switch springs back and disconnects the circuit. Through mechanical program control, precise intermittent lighting is achieved, reducing the time of ineffective lighting and improving the light energy utilization rate. While controlling the lighting, the speed-changing structure 49 simultaneously adjusts the spectrum. At this time, the cam 46 drives the inner serrated ring 491 to rotate, and the inner serrated ring 491 drives the large gear 492 to rotate, completing the first-stage reduction. The large gear 492 drives the small gear 493 to realize the speed conversion. The small gear 493 drives the outer gear ring 494, which in turn drives the dimming cover 410 to optimize the speed rotation. The dimming cover 410 achieves a smooth spectral transition through the continuous change of the color-changing filter film on its inner surface, accurately simulating the natural spectral changes from sunrise to sunset, providing the most suitable light quality environment for pasture at different growth stages. Dynamic spectral adjustment promotes the photosynthetic efficiency of pasture seedlings, shortens the cultivation cycle, and improves the robustness of seedlings. After one cycle is completed, all components are reset, the dimming mask 410 returns to the initial spectrum state, the micro switch 48 is in the off state, and the system is ready to start the next working cycle.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
