DETAILED DESCRIPTION

[0033] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the specific implementation methods, structures, features and effects of the utility model application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0034] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] like Figures 1 to 4 As shown, an embodiment of the utility model provides an LED light source planting system, which includes: a planting part and an irradiation part;

[0036] The planting part includes a water tank 1 and a planting cover 2, the planting cover 2 covers the water tank 1, the planting cover 2 is evenly distributed with a plurality of planting holes 3, and a plurality of nozzles 4 are axially arranged in the water tank 1 for spraying water to the planting cover 2;

[0037] The irradiation part includes a programmable motor 5, an LED lamp assembly 6 and a support rod. The programmable motor 5 is fixedly arranged at the end of the water tank 1. The output shaft of the programmable motor 5 extends along the axial direction of the water tank 1. The LED lamp assembly 6 is arranged above the planting cover 2. One end of the support rod is fixedly connected to the LED lamp assembly 6, and the other end is fixedly connected to the output shaft of the programmable motor 5, which is used to drive the LED lamp assembly 6 to swing back and forth.

[0038] The working process of the LED light source planting system is as follows:

[0039] In the traditional planting method, LED light panels are fixed on the top of each layer of the planting rack. The LED light panels must be the same width as the corresponding planting layer to provide comprehensive light irradiation to the planted plants. If the light quality and intensity are not well controlled, plant leaf heartburn is inevitable.

[0040] In the technical solution of the present application, the programmable motor 5 drives the LED lamp assembly 6 to swing back and forth through the support rod, and the LED lamp assembly 6 cyclically illuminates the planted seedlings on the surface of the planting cover 2, so that the multiple planted seedlings on the surface of the planting cover 2 receive uniform light.

[0041] The LED lamp assembly 6 of the device swings back and forth, cyclically irradiating the planted seedlings on the surface of the planting cover 2, avoiding heartburn of the planted seedlings in a local area of ​​the planting cover 2 due to continuous light exposure, so that the light intensity meets the growth needs of the plants without causing excessive damage to the plants, and saving energy compared to traditional planting methods.

[0042] At the same time, the plant seedlings are planted in the planting holes 3 , and a plurality of nozzles 4 spray mist water toward the planting cover 2 to provide nutrient solution for the plant roots, and the excess water on the inner surface of the planting cover 2 settles into the water tank 1 .

[0043] In the technical solution of the utility model, the device adopts a cyclic irradiation method for plant seedlings, which avoids continuous irradiation of plant seedlings and heartburn of plant leaves, while saving energy and optimizing the plant lighting method.

[0044] like Figure 2 or Figure 3 As shown, in a specific embodiment, the irradiation part also includes a Hall element 8, a first magnet 9 and a second magnet 10, the first magnet 9 and the second magnet 10 are symmetrically arranged on opposite sides of the end of the water tank 1, the Hall element 8 is fixedly connected to the middle part of the support rod, the first magnet 9 and the second magnet 10 are respectively located at opposite end points of the swing trajectory of the Hall element 8, the output end of the Hall element 8 is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the programmable motor 5.

[0045] In this embodiment, specifically, the irradiation part also includes a first limiting rod and a second limiting rod, one end of the first limiting rod and one end of the second limiting rod are respectively fixedly connected to the opposite sides of the end of the water tank 1, the first magnet 9 is installed at the other end of the first limiting rod, and the second magnet 10 is installed at the other end of the second limiting rod.

[0046] During the process of the programmable motor 5 driving the LED lamp assembly 6 to swing, when the Hall element 8 corresponds to the first magnet 9, the Hall element 8 generates a first electrical signal, and the controller changes the driving direction of the programmable motor 5; when the Hall element 8 corresponds to the second magnet 10, the Hall element 8 generates a second electrical signal, and the controller changes the driving direction of the programmable motor 5, so that the LED lamp assembly 6 can only swing back and forth between the first magnet 9 and the second magnet 10.

[0047] like Figure 1 As shown, in a specific embodiment, the support rod includes a first support rod 11 and a second support rod 12, one end of the first support rod 11 and one end of the second support rod 12 are respectively fixedly connected to the opposite ends of the LED lamp assembly 6, and the other end of the first support rod 11 and the other end of the second support rod 12 are respectively fixedly connected to the output shaft of the programmable motor 5.

[0048] In this embodiment, specifically, the output shaft of the programmable motor 5 extends along the lower surface of the bottom wall of the sink 1, the length of the output shaft of the programmable motor 5 is greater than the length of the sink 1, and the LED lamp assembly 6, the first support rod 11, the output shaft of the programmable motor 5 and the second support rod 12 are fixedly connected in sequence to form a rectangular shape.

[0049] Both ends of the LED lamp assembly 6 are respectively fixedly connected to the output shaft of the programmable motor 5, thereby improving the stability of the LED lamp assembly 6 when swinging.

[0050] like Figure 6 and Figure 7 As shown, it also includes two semi-elliptical plates 21, which are respectively fixedly connected to the brackets 20 at the opposite ends of the planting cover 2, the center of the ellipse of the semi-elliptical plate 21 coincides with the output shaft of the programmable motor 5, and the long axis of the semi-elliptical plate 21 extends in the vertical direction, and the long axis of the ellipse of the semi-elliptical plate 21 divides the radial cross-section of the planting cover 2 in half.

[0051] The first support rod 11 and the second support rod 12 have the same structure, both including a sleeve 22 and an inner rod 23, one end of the inner rod 23 is fixedly connected to the output shaft of the programmable motor 5, the other end of the inner rod 23 is inserted into one end of the sleeve 22, the other end of the sleeve 22 is fixedly connected to the LED lamp assembly 6, and one end of the sleeve 22 is rotatably connected to the roller 24, and the roller 24 rolls on the edge of the semi-elliptical plate 21.

[0052] The effects of the semi-elliptical plate 21, the sleeve 22 and the inner rod 23 are as follows:

[0053] If there is no semi-elliptical plate 21, sleeve 22 and inner rod 23 structure, during the reciprocating swing of the LED lamp assembly 6, the plant seedlings in the middle of the planting cover 2 receive more light than the plant seedlings on both sides of the planting cover 2;

[0054] In the present embodiment, the hub of the roller 24 contacts the edge of the semi-elliptical plate 21. When the LED lamp assembly swings from both sides to the middle of the planting cover 2, the roller 24 rolls from the short axis end of the ellipse to the long axis end of the ellipse, and the sleeve 22 and the inner rod 23 are relatively far apart. The distance between the LED lamp assembly 6 and the planting cover 2 increases, that is, the light intensity of the LED lamp assembly 6 on the seedlings in the middle of the planting cover 2 is weakened, and ultimately the seedlings in the middle of the planting cover 2 receive a small light intensity and a long time, while the seedlings on both sides of the planting cover 2 receive a large light intensity and a short time, thereby balancing the amount of artificial light radiation received by the seedlings on the surface of the planting cover 2.

[0055] like Figures 1 to 3 As shown, in a specific embodiment, it also includes a purification tank 13, which is arranged below the water tank 1, and the bottom wall of the water tank 1 and the upper port of the purification tank 13 are connected through a return pipe 14, and the upper port of the purification tank 13 is provided with an activated carbon filter layer 15, and a plurality of ultraviolet lamps 16 are arranged in sequence in the purification tank 13, and a submersible pump 17 is installed in the purification tank 13, and the water pipe 18 of the submersible pump 17 is respectively connected to the plurality of nozzles 4.

[0056] In this embodiment, specifically, in the purification tank 13, multiple ultraviolet lamps 16 simultaneously irradiate and sterilize the nutrient solution water body, and the submersible pump 17 transports the sterilized nutrient solution upward to the multiple nozzles 4, and sprays it to the inner surface of the planting cover 2. The nutrient solution after contacting the plant roots is first concentrated in the water tank 1, and then flows along the return pipe 14 to the activated carbon filter layer 15 to remove large particles of impurities, and then settles to the purification tank 13, where the nutrient solution is sterilized again. In this way, the nutrient solution is circulated and sprayed to the inner surface of the planting cover 2.

[0057] like Figure 2 or Figure 3 As shown, in a specific embodiment, it also includes a central groove 19, which is coaxially arranged in the water tank 1, and a plurality of the nozzles 4 are arranged in sequence in the central groove 19, and the return pipe 14 is connected to the bottom wall of the water tank 1 outside the central groove 19.

[0058] In this embodiment, specifically, the width of the central groove 19 is smaller than the width of the water tank 1. A time controller is provided, and the start time of the submersible pump 17 is set by the time controller, and the multiple nozzles 4 periodically spray mist water to the planting cover 2. When the multiple nozzles 4 do not spray water, a certain amount of water can be temporarily stored in the central groove 19, so that the environment between the planting cover 2 and the water tank 1 maintains a certain humidity;

[0059] At the same time, when the central tank 19 is full, the excess nutrient solution overflows to the periphery of the central tank 19 and flows along the return pipe 14 to the purification tank 13 .

[0060] like Figures 1 to 4 As shown, in a specific embodiment, a bracket 20 is further included, the water tank 1 is fixedly arranged at the upper end of the bracket 20, and the purification tank 13 is fixedly arranged at the lower end of the bracket 20.

[0061] In this embodiment, specifically, by providing the bracket 20 , the relative position relationship between the water tank 1 and the purification tank 13 can be fixed, and at the same time, the bracket 20 can provide an installation position for the programmable motor 5 .

[0062] like Figure 4 and Figure 5 As shown, in a specific implementation, the LED lamp assembly 6 includes a plurality of lamp beads arranged in an array, and each column of the lamp beads includes a red light lamp bead 601 , a blue light lamp bead 602 , and an infrared light lamp bead 603 .

[0063] In this embodiment, specifically, red light plays an important role in the development of photosynthetic organs, plant morphology, and the synthesis of phenolic compounds. Supplementing red light can significantly increase the dry matter accumulation of plants and the rapid expansion of leaf area, and can also significantly increase the photosynthetic rate of plants, and at the same time increase the chlorophyll content, soluble sugar and total sugar content. In addition, it can also reduce the chlorophyll a / b value and total nitrogen content.

[0064] Blue light is beneficial to the accumulation of soluble proteins, and can also increase the chlorophyll content and strengthen photosynthesis. When supplemented with blue light, the thickening of the stems of plant seedlings is beneficial to accelerating plant development. At the same time, blue light can regulate stomatal opening, promote cell membrane permeability and cytoplasmic circulation.

[0065] Far-red light not only affects the photosynthesis efficiency of plants, but also regulates the photomorphogenesis of plants. Supplementing far-red light can promote the regulation of phytochrome interaction factors by phytochrome B, activate plant auxin synthesis genes, induce shade avoidance responses in plants, thereby accelerating plant growth, while reducing pigment concentration, and significantly improving plant antioxidant capacity, flavonoid content, polyphenol content, and anthocyanin content.

[0066] Specifically, in each column of lamp beads, the light quality intensity ratio of the three color lamp beads is: red light lamp bead 601: blue light lamp bead 602: far red light lamp bead 601 = 3:1:1.

[0067] In a specific embodiment, the planting cover 2 includes a shell and a rock wool board attached to the inner surface of the shell.

[0068] In this embodiment, specifically, the shell is made of PP (polypropylene) material to provide support for the rock wool board. The shell is evenly distributed with multiple planting holes 3. The operator inserts the planting seedlings into the rock wool board through the planting holes 3. The roots of the planting seedlings can extend in the rock wool board, providing growth space for the roots of the planting seedlings.

[0069] Specifically, the thickness of the rock wool board is greater than or equal to 15 cm.

[0070] like Figure 2 As shown, in a specific embodiment, the radial cross-section of the implantation cover 2 is Π-shaped.

[0071] In this embodiment, specifically, the radial cross-section of the planting cover 2 is Π-shaped, and multiple planting holes 3 are evenly distributed on the left and right sides and the upper side of the planting cover 2. Compared with the arc-shaped planting cover 2, relatively more planting hole 3 positions can be provided.

[0072] like Figure 3 As shown, in a specific embodiment, the radial cross-section of the planting cover 2 is arc-shaped.

[0073] In the present embodiment, specifically, the radial cross-section of the planting cover 2 is arc-shaped. Since the swing trajectory of the LED lamp assembly 6 is also arc-shaped, the distance value between the LED lamp assembly 6 and the planting cover 2 is always constant, thereby ensuring that the light quality intensity received by the planting seedlings at different positions of the planting cover 2 remains consistent, so that the growth of the plants at the time of harvest is consistent.

[0074] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
