Description

Technical Field

[0001] This utility model relates to the field of fruit seedling technology, and in particular to a fruit seedling greenhouse with automatically adjustable light. Background Technology

[0002] A fruit seedling greenhouse is a building used for plant cultivation, with a history dating back to the period of agricultural development and technological advancement. With the development of the Industrial Revolution and modern agriculture, greenhouse technology has gradually matured and become widely used. Its core function is to create suitable environmental conditions, such as constant temperature, humidity, and light, to promote rapid plant growth and high yields. Greenhouses are equipped with automatic monitoring equipment to monitor parameters such as temperature and humidity in real time, and adjust them through an intelligent control system to ensure the stability and optimization of the plant growth environment.

[0003] In existing technologies, the light regulation systems in fruit seedling greenhouses typically use a fixed mode, making it impossible to dynamically adjust them according to the plant's growth needs. This problem stems from the limitations of traditional greenhouse design: different plants have significantly different requirements for light intensity and wavelength, and traditional facilities struggle to meet these differences, leading to an unstable light environment that affects plant growth efficiency and quality. Furthermore, insufficient light can cause poor leaf development and uneven fruit nutrition, while excessive light can cause light damage.

[0004] In response to this technical problem, this application proposes a fruit seedling greenhouse with automatically adjustable light. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatically adjustable fruit seedling greenhouse that can precisely reflect light to meet the growth needs of fruit seedlings on the seedling platform, promote their healthy development, and allow the shielding and extension panels to be extended to protect the seedling platform from the effects of severe weather.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatically adjustable light-adjustable fruit seedling greenhouse includes a cultivation platform. A fixed frame is fixedly connected to the top of the cultivation platform. Lighting platforms are fixedly connected to the left and right sides of the top of the fixed frame. A unidirectional motor is fixedly connected to both the front and rear ends of the inner wall of the lighting platform. The drive end of the unidirectional motor is connected to a reflector through a light group. A light recognition device is provided at the top of the reflector. A bidirectional motor is fixedly connected to the bottom of the inner wall of the cultivation platform. A semi-toothed plate is fixedly connected to both the front and rear drive ends of the bidirectional motor. A second semi-toothed plate is engaged with the right end of the first semi-toothed plate. The opposite ends of the second semi-toothed plate and the first semi-toothed plate are both connected to the seedling platform through a receiving group.

[0008] Furthermore, the illumination group includes worm gears fixedly connected to the unidirectional motor drive end, and worm wheels are meshed with the outer walls of the worm gears.

[0009] Furthermore, a transmission tube is fixedly connected to the inner wall of the worm gear at the top end, a transmission shaft is fixedly connected to the inner wall of the worm gear at the bottom end, and a rotating plate is fixedly connected to the top end of the transmission tube.

[0010] Furthermore, a rotating frame is fixedly connected to the bottom end of the reflector, a second bevel gear is fixedly connected to the bottom end of the rotating frame, and a first bevel gear is fixedly connected to the top end of the transmission shaft. The first bevel gear and the second bevel gear are meshed together.

[0011] Furthermore, the receiving assembly includes fixed plates that are fixedly connected to opposite ends of the first and second half-tooth plates, and lifting plates that are rotatably connected to the top of each fixed plate. The tops of the lifting plates are rotatably connected to the four sides of the outer wall of the seedling tray.

[0012] Furthermore, a support plate is fixedly connected to one of the opposite ends of the first and second half-tooth plates, a shield is rotatably connected to the top of the first support plate, a support plate is rotatably connected to one of the opposite ends of the shield, and the bottom end of the second support plate is rotatably connected to the inner wall of the cultivation platform.

[0013] Furthermore, each of the inner walls of the shielding plate is fixedly connected with a number of return springs, and each of the other ends of the return springs is fixedly connected with an extension plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this invention, an external controller starts a unidirectional motor, which drives the worm gear and worm wheel to rotate, thereby controlling the transmission tube and transmission shaft to adjust the plane and elevation angle of the reflector plate. This adjustment mechanism can accurately reflect light, meeting the growth needs of fruit seedlings on the seedling platform and promoting their healthy development.

[0016] 2. In this invention, during windy or rainy weather, the bidirectional motor is activated, driving the first and second half-toothed plates to lift the fixed plate and retract the seedling tray into the inner cavity of the cultivation platform. Simultaneously, the first and second support plates cooperate to unfold the shielding plate and extension plate, protecting the seedling tray from severe weather. Reverse starting of the motor quickly restores the seedling tray to its normal state, ensuring plant safety and providing convenient and efficient operation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a fruit seedling greenhouse with automatically adjustable lighting, comprising a cultivation platform 1, a fixed frame 2 fixedly connected to the top of the cultivation platform 1, and lighting platforms 3 fixedly connected to the left and right sides of the top of the fixed frame 2. A unidirectional motor 16 is fixedly connected to both the front and rear ends of the inner wall of the lighting platform 3. The drive end of the unidirectional motor 16 is connected to a reflector 6 via a lighting assembly. A light recognition device is provided at the top of the reflector 6. The lighting assembly includes a worm gear 17 fixedly connected to the drive end of the unidirectional motor 16. Worm wheels 18 are meshed with the outer wall of the worm gear 17. A transmission tube 19 is fixedly connected to the inner wall of the top worm wheel 18, and a transmission shaft 20 is fixedly connected to the inner wall of the bottom worm wheel 18. (See reference...) Figure 4 A rotating plate 4 is fixedly connected to the top of the transmission tube 19, a rotating frame 5 is fixedly connected to the bottom of the reflector plate 6, a bevel gear 22 is fixedly connected to the bottom of the rotating frame 5, and a bevel gear 21 is fixedly connected to the top of the transmission shaft 20. The bevel gear 21 and the bevel gear 22 are meshed together.

[0026] Specifically: In the intelligent environmental control system for fruit seedling greenhouses, when multiple varieties of fruit seedlings placed on the surface of the seedling tray 9 in the core cultivation area have different light requirements due to differences in their growth stages, the greenhouse central control system will capture the light intensity data of each area in real time through the light recognition device. At this time, the operator can issue control commands through the integrated human-machine interface. The external controller then starts the high-precision unidirectional motor 16, which drives the stainless steel worm gear 17 to rotate in a directional manner after the torque is matched by the planetary reducer. The worm gear 17 and the double worm wheel 18 form a dual transmission mechanism: the upper worm wheel 18 transmits motion through the 304 stainless steel transmission pipe 19 connected by the flange, driving the high-strength aluminum alloy rotating plate 4 to rotate in a plane. At this time, the six-degree-of-freedom rotating frame 5 hinged to the edge of the rotating plate 4 drives the high-reflectivity nano-coated reflector 6 to achieve azimuth angle adjustment. With an elevation range of ±0.5°, when an elevation angle adjustment is required, the lower worm gear 18 transmits torque through the high-carbon steel transmission shaft 20 connected by a keyway. The torque is then changed by the orthogonally arranged bevel gear set, driving the pitch mechanism of the rotating frame 5, enabling the reflector 6 to achieve continuous elevation angle adjustment from 0 to 60°. Combined with the adjustable spectrum LED supplemental lighting system at the top of the greenhouse, a dynamic light environment control network is formed. The entire adjustment process is controlled in a closed loop by a PLC controller. Combined with the soil temperature and humidity sensor and the leaf surface photosynthetic efficiency monitoring probe installed at the bottom of the seedling platform 9, an intelligent light regulation system based on crop physiological feedback is constructed. This ensures that different varieties of fruit seedlings can obtain the optimal light quantum flux density during the budding, growth, and hardening stages. At the same time, the directional reflective characteristics of the reflector 6 effectively reduce the overall energy consumption of the greenhouse by up to 35% and avoid the risk of leaf burn caused by direct sunlight.

[0027] Reference Figure 5 A bidirectional motor 10 is fixedly connected to the bottom of the inner wall of the cultivation platform 1. Half-tooth plates 15 are fixedly connected to the front and rear drive ends of the bidirectional motor 10. A second half-tooth plate 24 is meshed with the right end of the first half-tooth plate 15. The opposite ends of the second half-tooth plate 24 and the first half-tooth plate 15 are connected to the seedling platform 9 via a receiving assembly. The receiving assembly includes a fixed plate 14 fixedly connected to the opposite ends of the first half-tooth plate 15 and the second half-tooth plate 24. A lifting plate 13 is rotatably connected to the top of each fixed plate 14. The top of the lifting plate 13 is rotatably connected to the four sides of the outer wall of the seedling platform 9. The opposite ends of the half-tooth plate 15 and the half-tooth plate 24 are fixedly connected to the support plate 11. The top of the support plate 11 is rotatably connected to the shielding plate 7. The opposite end of the shielding plate 7 is rotatably connected to the support plate 22. The bottom end of the support plate 22 is rotatably connected to the inner wall of the seedling platform 1. Several return springs 23 are fixedly connected to the inner wall of the shielding plate 7. The other end of the return springs 23 is fixedly connected to the extension plate 8.

[0028] Specifically: In the extreme climate protection system for fruit seedling greenhouses, when the outdoor meteorological monitoring station detects an instantaneous wind speed ≥ level 8 or a rainstorm intensity > 50 mm / h, an automatic protection protocol will be triggered based on the transmitted warning signal. At this time, the central controller starts the waterproof bidirectional servo motor 10, which drives the first half-tooth plate 15 to rotate clockwise through the coupling, forming a non-complete gear meshing transmission with the second half-tooth plate 24. This transmission system, through the fixed plate 14 supported by four-point contact ball bearings, drives the lifting plate 13 with linear guide rails to move vertically, so that the seedling tray 9 carrying 12 seedling trays smoothly descends into the 304 stainless steel inner cavity of the cultivation tray 1 at a speed of 30 mm / s. At the same time, the pneumatic locking mechanism is triggered to complete the positioning. During the lifting process, the hinged support plate 11 and the support plate 2 with ball splines form a four-bar linkage mechanism, driving the double-sided shielding plates 7 to move symmetrically along the precision linear slide rails. With the help of the extension plate 8, under the action of the return spring 23, a three-stage extension is achieved, ultimately forming a coverage area of ​​6.8 m². 2 A continuous protective canopy is constructed. The canopy's edges are equipped with EPDM sealing strips, forming a sealed cavity with the side wall of the cultivation platform 1. This cavity can withstand rainfall impacts of up to 100 mm / h. When the system operates in reverse, the bidirectional motor 10 rotates counterclockwise, increasing the output torque to 120 N·m via a harmonic reducer, driving the seedling platform 9 to return to its cultivation position at a uniform speed of 25 mm / s. The synchronously unfolding shield 7 moves laterally via a servo motor-driven synchronous belt transmission system. The extension plate 8 folds and retracts with the assistance of a pre-tensioned constant-force spring. The entire process is monitored in real-time by laser displacement sensors, and a protection action log is generated through the greenhouse management cloud platform. This protective system can complete the entire process within 38 seconds, effectively preventing plant lodging caused by strong winds and substrate loss caused by heavy rain, while maintaining the internal microenvironment during the containment period.

[0029] Working Principle: When the light exposure to several fruit seedlings placed on the seedling platform 9 needs adjustment, the external controller activates the unidirectional motor 16, which drives the worm gear 17 to rotate. This worm gear 17 then drives the worm wheel 18 to rotate. When the upper worm wheel 18 rotates, it drives the transmission tube 19, causing the rotating plate 4 to rotate. This allows the reflector 6 connected to the rotating frame 5 on the rotating plate 4 to adjust its plane angle. Simultaneously, activating the lower worm wheel 18 drives the transmission shaft 20 to rotate. This transmission shaft 20, through bevel gear 21, drives bevel gear 22, which in turn drives the rotating frame 5 to adjust the elevation angle of the reflector 6. This ensures that the reflector 6 reflects appropriate light to match the seedling growth. The seedlings on the seedling platform 9 have growth needs. When it is windy or rainy and the plants on the seedling platform 9 need to be sheltered, the bidirectional motor 10 can be started to drive the half-tooth plate 15 to rotate and drive the half-tooth plate 24. This causes the fixed plate 14 to drive the lifting plate 13 to retract the seedling platform 9 and shelter it in the inner cavity of the cultivation platform 1. With the cooperation of the support plate 11 and the support plate 22, the shielding plate 7 moves relative to the support plate 11. Under the elastic force of the return spring 23, the extension plate 8 unfolds and cooperates with the shielding plate 7 to shield the top of the seedling platform 9, which facilitates the protection of the seedling platform 9. When the bidirectional motor 10 is started in the opposite direction, the seedling platform 9 can be raised again and the shielding plate 7 can be unfolded to both sides.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
