Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to an adaptive light-adjusting device for greenhouse tomato growth. Background Technology

[0002] The greenhouse tomato growth adaptive light adjustment device is an intelligent system that can provide "customized sunlight" for tomatoes in the greenhouse on demand, precisely and automatically, and adjust the light scheme in real time according to the growth of tomatoes and weather changes. Greenhouse tomatoes require light intensity regulation during their growth. Supplemental lighting typically involves hanging multi-colored grow lights above the tomatoes. Sensors monitor plant height and adaptively adjust the distance between the grow lights and the tomato canopy to ensure uniform light intensity across the plant. However, as the tomato plants grow to a certain height, the grow lights need to be raised accordingly. This process can lead to uneven light distribution, where upper leaves block light, resulting in insufficient light in the lower rows and impacting growth efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an adaptive light-adjusting device for greenhouse tomato growth, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an adaptive light-adjusting device for greenhouse tomato growth, comprising a main body, a winding motor bolted to the top of the main body, two limiting ears fixedly connected to the left and right sides of the main body, and further comprising: The oscillating mechanism is installed on the side wall of the main body to improve the uniformity of light during dimming. The swing mechanism includes two rotating rods located on the left and right sides of the main body, and the rotating rods are hollow. A limiting mechanism is installed on the side wall of the main body to ensure the synchronicity of the rotation of the left and right rotating rods of the main body; The limiting mechanism includes two C-shaped frames installed on the side wall of the main body. A return spring is fixedly connected to the inner top wall of the C-shaped frame. In the initial state, the return spring is in a compressed state.

[0005] Furthermore, the main body includes: The tensioning assembly is installed on the top of the main body and is used to adjust the lighting height of the main body.

[0006] Furthermore, the swing mechanism also includes: Auxiliary components are installed inside the rotating rod; The folding component is installed on the side wall of the auxiliary component to ensure uniform illumination of the main body.

[0007] Furthermore, the restricted agencies also include: The sliding assembly is installed on the side wall of the C-shaped frame.

[0008] Furthermore, the traction assembly includes a drive rod disposed at the top of the main body, and two rope coils are fixedly connected to the outer surface of the drive rod; Two connecting plates are rotatably connected to the outer surface of the drive rod; The ends of the two rope coils are fixedly connected to the top of the main body.

[0009] Furthermore, the rotating rod is slidably connected inside the limiting ear; The auxiliary components include a limiting frame that is fixedly connected to the side wall of the rotating rod; The rotating rod is internally connected to a protruding plate, the bottom of which is inclined. The protruding plate is inclined inside the rotating rod. When the inclined end of the bottom of the protruding plate is squeezed, the protruding plate rotates upward inside the rotating rod.

[0010] Furthermore, the folding assembly includes a folding reflector disposed between the two rotating rods; The bottom of the folding reflector is rotatably connected between two rotating rods, and the top of the folding reflector is connected to the output end of the winding motor via a rope reel.

[0011] Furthermore, an auxiliary rod is fixedly connected to the side of the folding reflector near the limiting frame one, and the auxiliary rod is slidably disposed between the limiting frame one and the rotating rod; The folding reflector is composed of folding reflectors with shorter and longer widths pieced together. When the folding reflector is folded and retracted, it will present an inverted V-shaped structure.

[0012] Furthermore, the bottom of the return spring is fixedly connected to the top of the main body; The C-shaped frame is slidably connected inside the two limiting ears; The sliding assembly includes two inclined blocks that are fixedly connected to the bottom of the C-shaped frame.

[0013] Furthermore, a second limiting frame is slidably connected to the outer surface of the C-shaped frame on the side wall of the main body, and the second limiting frame is fixedly connected to the side wall of the main body; The left and right outer walls of the C-shaped frame are both serrated.

[0014] The present invention has the following beneficial effects: 1. This invention, through the inverted V-shaped reflective surface formed by folding the reflector, can refract light that is originally vertically downward into light that is obliquely downward, so that the refracted light can directly illuminate the lower part of the tomato plant, eliminate the layered light difference on the side wall of the tomato plant, ensure the uniformity of the light coverage and the light intensity when the light is increased, and ensure the growth efficiency of the tomato.

[0015] 2. In this invention, when the C-shaped frame slides upwards after the return spring releases its potential energy, it also pushes the ends of the rotating rods on both sides of the main body through the tilting block, further assisting the consistency of the rotation of the rotating rods on both sides. This avoids inconsistent unfolding of the rotating rods on both sides of the main body during the process of lowering the folding reflector with the rope roll, thereby preventing uneven light exposure on both sides of the plant and tilting of the main body's light, ensuring the stability and synchronization of the rotation of the rotating rods and the folding reflector, and improving the growth efficiency of tomatoes.

[0016] 3. In this invention, when the folding reflector is folded and retracted, the folding reflector will drive the auxiliary rod to slide and make the auxiliary rod stuck between two protrusions on the raised plate. By restricting the auxiliary rod by the raised plate, the folding reflector can be prevented from shaking or re-expanding and retracting due to airflow disturbance in the greenhouse after folding and retracting. This prevents the light reflected by the folding reflector from producing light spots and flickering on the tomato leaves, and improves the stability of photosynthetic growth of tomatoes during the growth process.

[0017] 4. The present invention, through the flow formed when the airflow passes through the folded reflector, can prevent dust and powder from adhering to the surface of the folded reflector, ensure the smoothness of the reflective surface of the folded reflector, reduce the adhesion of dust on the reflective surface of the folded reflector, not only avoid dust blocking the reflected light, but also ensure the stability of the reflection process and improve the intensity of reflected light.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8 As shown, this invention is an adaptive light-adjusting device for greenhouse tomato growth, comprising a main body 1, a winding motor 101 bolted to the top of the main body 1, and two limiting ears 102 fixedly connected to the left and right sides of the main body 1, and further comprising: The swing mechanism 2 is installed on the side wall of the main body 1 to improve the uniformity of light during the dimming process. The swing mechanism 2 includes two rotating rods 211 disposed on the left and right sides of the main body 1, and the rotating rods 211 are hollow. The limiting mechanism 3 is installed on the side wall of the main body 1 to ensure the synchronicity of the rotation of the left and right rotating rods 211 of the main body 1; The limiting mechanism 3 includes two C-shaped frames 311 disposed on the side wall of the main body 1. A return spring is fixedly connected to the top inner wall of the C-shaped frame 311. In the initial state, the return spring is in a compressed state.

[0024] Entity 1 includes: The tensioning component 11 is installed on the top of the main body 1 and is used to adjust the illumination height of the main body 1.

[0025] The swing mechanism 2 also includes: Auxiliary component 21 is installed inside the rotating rod 211; Folding component 22 is installed on the side wall of auxiliary component 21 to ensure uniform illumination of the main body 1.

[0026] Restriction agency 3 also includes: Sliding assembly 31 is mounted on the side wall of C-shaped frame 311.

[0027] The traction assembly 11 includes a drive rod 111 disposed on the top of the main body 1, and two rope coils 112 are fixedly connected to the outer surface of the drive rod 111; Two connecting plates 113 are rotatably connected to the outer surface of the drive rod 111; The ends of the two rope rolls 112 are fixedly connected to the top of the main body 1. When the main body 1 is started, it will irradiate the top of the tomato plant. Then, the external detection sensor drives the drive rod 111 to rotate according to the height of the tomato plant, and the two rope rolls 112 drive the main body 1 to adjust its height.

[0028] The rotating rod 211 is slidably connected inside the limiting ear 102; The auxiliary component 21 includes a limiting frame 212 that is fixedly connected to the side wall of the rotating rod 211; The rotating rod 211 is rotatably connected to a protruding plate 213, and the bottom of the protruding plate 213 is inclined. The protruding plate 213 is inclined inside the rotating rod 211. When the inclined end of the bottom of the protruding plate 213 is squeezed, the protruding plate 213 rotates upward inside the rotating rod 211.

[0029] The folding assembly 22 includes a folding reflector 221 disposed between two rotating rods 211; The bottom of the folding reflector 221 is rotatably connected between two rotating rods 211, and the top of the folding reflector 221 is connected to the output end of the winding motor 101 through a rope reel. When the winding motor 101 operates, the rotating rods 211 drive the folding reflector 221 to rotate downwards and tilt. During the rotation, the rotating rods 211 will slide forward inside the limiting ear 102.

[0030] An auxiliary rod 222 is fixedly connected to the side of the folding reflector 221 near the limiting frame 212. The auxiliary rod 222 is slidably disposed between the limiting frame 212 and the rotating rod 211. The folding reflector 221 is composed of folding reflectors 221 with shorter width and longer width in sequence. When the folding reflector 221 is folded and retracted, it can present an inverted V-shaped structure. When the raised plate 213 rotates, the protrusions on the side wall will extend out of the slot of the rotating rod 211. When the folding reflector 221 is retracted and folded, the folding reflector 221 will drive the auxiliary rod 222 to slide, and the auxiliary rod 222 will be stuck between the two protrusions on the raised plate 213.

[0031] The bottom of the return spring is fixedly connected to the top of the main body 1; The C-shaped frame 311 is slidably connected inside the two limiting ears 102; The sliding assembly 31 includes two inclined blocks 312 fixedly connected to the bottom of the C-shaped frame 311.

[0032] A second limiting frame 313 is slidably connected to the outer surface of the C-shaped frame 311 on the side wall of the main body 1, and the second limiting frame 313 is fixedly connected to the side wall of the main body 1. The left and right outer walls of the C-shaped frame 311 are both serrated; The inclined surface of the inclined block 312 will cause the C-shaped frame 311 to slide to one side during the upward sliding process. At this time, the toothed structure of the side wall of the C-shaped frame 311 will fit into the inner wall of the limiting frame 313.

[0033] In use, first connect the main body 1 to the ropes on the two rope reels 112. At the same time, install the drive rod 111 along with the main body 1 onto the fixed frame in the greenhouse through the two connecting plates 113. Then, the staff connects the drive rod 111 to the external drive motor. After that, the main body 1 is started. When the main body 1 is working, it will irradiate the top of the tomato plant. Then, the external detection sensor drives the drive rod 111 to rotate according to the height of the tomato plant. The two rope reels 112 drive the main body 1 to adjust its height, so as to achieve the purpose of adaptive light adjustment for tomato growth in the greenhouse.

[0034] When the height difference between the main body 1 and the bottom area of ​​the tomato plant is not significant, the external detection sensor will not activate the winding motor 101. At this time, the two rotating rods 211 on both sides of the main body 1 will cause the folding reflector 221 to lean against the side wall of the main body 1, and the folding reflector 221 and the main body 1 will be set approximately horizontally. At this time, the folding reflector 221 will present a flat reflective surface, which can reflect the light or natural light of the adjacent main body 1 to the side area of ​​the adjacent tomato plant, improving the utilization rate of light. When the main body 1 is raised due to the growth of the tomato plant, the winding motor 101 is activated to drive the rope reel to rotate and lower the rope connected to the folding reflector 221. At this time, the folding reflector 221 and the rotating rods 211 on both sides of the main body 1 will rotate downward around the limiting ear 102 under their own weight. At this time, the rotating rods 211 will cause the folding reflector 221 and the irradiation surface of the main body 1 to be set at an angle, presenting a flat reflective surface. Figure 7 and Figure 8 In this state, the folding reflector 221, along with the rotating rod 211, will fold and retract under the pull of the rope during rotation, such as... Figure 8 In the state shown in G, the folded reflector 221 will form multiple inverted V-shaped structures, with the wider plate on one side of the inverted V structure being longer than the plate on the other side. Through the inverted V-shaped reflective surface formed by the folded reflector 221, the light that was originally vertically downward can be refracted into light that is obliquely downward, so that the refracted light can directly illuminate the middle and lower part of the tomato plant, eliminating the layered light difference on the side wall of the tomato plant, ensuring the uniformity of the light coverage and the light intensity of the main body 1 during the process of increasing the light, and ensuring the growth efficiency of the tomato.

[0035] When the winding motor 101 operates, causing the rotating rod 211 to drive the folding reflector 221 to rotate downwards and tilt, the rotating rod 211 will slide forward inside the limiting ear 102 during rotation. Simultaneously, the return spring will release its accumulated elastic potential energy, pushing the C-shaped frame 311 to cause the tilting block 312 to slide upwards during the rotation of the rotating rod 211. When the rotation amplitudes of the rotating rods 211 on the left and right sides of the main body 1 are inconsistent, the end of the rotating rod 211 with the smaller rotation amplitude will slide to one side of the C-shaped frame 311 during its upward sliding, passing through the inclined surface of the tilting block 312. At this time, the teeth on the sidewall of the C-shaped frame 311... The structure will then fit into the inner wall of the limiting frame 313, limiting the rotation amplitude of the rotating rod 211 on the other side until the rotation amplitudes of the rotating rods 211 on both sides are equal. At the same time, when the C-shaped frame 311 slides upward with the release of potential energy from the return spring, it will also push the ends of the rotating rods 211 on both sides of the main body 1 through the tilting block 312, further assisting the consistency of the rotation of the rotating rods 211 on both sides of the main body 1, avoiding the inconsistent unfolding amplitude of the rotating rods 211 on both sides of the main body 1 during the process of driving the folded reflector 221 down with the rope roll, thereby preventing uneven light exposure on both sides of the plant and the tilting of the main body 1, ensuring the stability and synchronization of the rotation of the rotating rods 211 and the folded reflector 221, and improving the growth efficiency of tomatoes.

[0036] As the rotating rod 211 rotates downwards, the C-shaped frame 311, under the potential energy of the return spring, drives the inclined block 312 to slide upwards synchronously. The rotating rod 211 will drive the protruding plate 213 to rotate synchronously. When the protruding plate 213 rotates, the inclined end of the protruding plate 213 will be pushed by the inclined surface of the inclined block 312 to rotate within the rotating rod 211. When the protruding plate 213 rotates, the protrusion on the side wall will extend out of the slot of the rotating rod 211. When the folding reflector 221 is retracted and folded, the folding reflector 221 will drive the auxiliary rod 222 to slide, and the auxiliary rod 222 will be stuck between the two protrusions on the protruding plate 213. By restricting the auxiliary rod 222 by the protruding plate 213, the folding reflector 221 can be prevented from shaking or re-expanding and retracting due to the airflow disturbance in the greenhouse after folding and retracting. This prevents the light reflected by the folding reflector 221 from producing light spots and flickering on the tomato leaves, and improves the stability of photosynthetic growth of tomatoes during growth.

[0037] When the folding reflector 221 is pulled by the rope and forms an inverted V-shape, the concave area facing the bottom of the folding reflector 221 allows the airflow inside the greenhouse to form an airflow vortex that washes over the reflective surface of the folding reflector 221. The flow formed by the airflow passing over the folding reflector 221 can prevent dust and powder from adhering to the surface of the folding reflector 221, ensuring the smoothness of the reflective surface of the folding reflector 221, reducing the adhesion of dust on the reflective surface of the folding reflector 221, avoiding dust from blocking the reflected light, ensuring the stability of the reflection process, and improving the intensity of reflected light.
