Description

Technical Field

[0001] The present invention relates to the technical field of planting racks, and in particular to an automatic light-supplementing planting rack for hydroponic vegetables. Background Art

[0002] Hydroponic vegetables refer to vegetables whose roots mostly grow in the nutrient solution layer and are only provided with water, nutrients and oxygen by the nutrient solution, which is different from vegetables cultivated in the traditional soil cultivation form. Planting racks are generally used in the hydroponic process, and supplementary light is needed to assist the growth of vegetables. For example, the application number is CN201821644093.1, a lightweight multi-layer automatic light-supplementing orchid planting rack, which has a structure on the planting rack body: multiple orchid planting layers built of lightweight pipes, water trays, plastic drainage hoses and releasable tie straps, wherein each orchid planting layer is layered by orchid growth and lighting space, orchid pot suspension The system consists of three layers: a hanging rack and a water tray rack. The supplemental lighting circuitry consists of a timer power switch, a DC power converter, a light sensor switch, a light adjustment switch, a plant supplemental light, and wiring. Its purpose and effect is to provide a product that solves space utilization, automatically supplements light, and provides drainage for orchid cultivation. It is primarily suitable for home use, facilitating transport, installation, and disassembly, allowing for the placement of multiple orchid pots for batch planting, accommodating orchid pots of varying sizes, simplifying drainage management, and adapting to varying light and dark environments. It can fully utilize sunlight to reduce energy consumption or conserve supplemental lighting energy.

[0003] During the planting process, the existing planting racks are generally fixed or manually disassembled and adjusted, and the distance between the vegetables and the fill light cannot be automatically adjusted. As a result, the vegetables will get close to the fill light during their upward growth, making the subsequent fill light intensity too high, which is not conducive to the growth of the vegetables. In addition, if the fill light is too close to the plants, the heat of the fill light will be transferred to the vegetables and may burn them. Summary of the Invention

[0024] After the sliding block is switched by the second motor, the positioning slot and the positioning rod are interlaced and matched, thereby locking the rotation of the current driving support rod, and then completing the height adjustment of the planting frame. Subsequently, under the action of the first protrusion and the second protrusion, the lower end driving support rod will not affect the fixation of the upper end driving support rod when rotating, thereby realizing the height adjustment of the single-layer planting frame.

DETAILED DESCRIPTION

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figures 1 to 13As shown, an automatic light-filling planting rack for hydroponic vegetables includes several bracket bodies 1, each bracket body 1 is composed of four first pillars 101 and two sets of upper and lower second pillars 102, a light-filling component 5 is fixedly installed at the bottom of the upper second pillar 102, each first pillar 101 is provided with a slide groove 103 running through the column body, adjacent slide grooves 103 are slidably installed inside thereof with connecting components 4, a planting frame 3 for planting vegetables is fixedly installed inside the connecting component 4, a driving support rod 107 for driving the connecting component 4 to move is rotatably installed inside one of the first pillars 101, and a limiting support rod 106 is provided inside the remaining first pillars 101;

[0042] A support leg 2 is fixedly installed at the bottom of the bracket body 1 at the lowest end, and a first motor 6 is fixedly installed inside one of the support legs 2. The output end of the first motor 6 is fixedly connected to the driving support rod 107 at the lowest end. A docking hole 1071 is provided at the upper end of each driving support rod 107, and a docking rod 1072 is provided at the lower end of each driving support rod 107. The docking hole 1071 and the docking rod 1072 are combined and connected. A plurality of first protrusions 10 are provided in the docking hole 1071, and a plurality of adaptation grooves 13 are provided on the rod body of the docking rod 1072. A second protrusion 11 is installed inside the adaptation groove 13 through a support spring 12.

[0043] In the present application, the docking hole 1071 is combined with the docking rod 1072, and the first protrusion 10 and the second protrusion 11 are supported by the support spring 12, so that the first motor 6 is started to drive the multiple driving rods 107 to rotate synchronously;

[0044] When adjusting the height of the planting frame 3, the present application needs to start from the top and adjust downwards one by one. During the adjustment process, in order to prevent the driving support rod 107 from rotating again after the upper end has completed the adjustment, the driving support rod 107 at the lower end is rotated. When the upper end is locked, the support spring 12 is used to shrink the second protrusion 11, so that the first protrusion 10 and the second protrusion 11 of the current layer are separated, and the driving support rod 107 locked at the upper end will not rotate, thereby ensuring the height of the planting frame 3. By utilizing the above-mentioned structural combination, the present application can drive multiple driving support rods 107 through a single first motor 6, and realize the control of the rotation of each driving support rod 107, so that the present application can meet the requirements of adjusting the height of each layer of planting frame 3, so that the distance between the planting frame 3 and the current fill light component 5 is properly adjusted.

[0045] In this embodiment, one of the first pillars 101 is fixedly mounted with a slide rail 7, a slide seat 9 is slidably mounted inside the slide rail 7, and an infrared sensor 8 for detecting the height of vegetables is fixedly mounted inside the slide seat 9. In order to enable this application to automatically adjust the fill light distance and effect, by adjusting the height of the slide seat 9 on the slide rail 7, the detection position of the infrared sensor 8 is set, and then the infrared sensor 8 is used to detect the current position. When vegetables are detected passing by, their data are counted. When the vegetables on multiple planting racks grow too high, the first motor 6 and the connecting component 4 are started to adjust the spacing of each planting frame 3 from top to bottom. When filling light, if the distance from the plant is too far, it may not have the effect of filling light on the plant, resulting in waste. However, if the fill light is too close to the plant, it may burn the plant. For this reason, the distance and effect of filling light can be automatically adjusted through this application, thereby ensuring the growth of vegetables.

[0046] It should be noted that the connecting assembly 4 includes four sliders 401, each slider 401 is fixedly connected to the planting frame 3, each slider 401 is slidably installed inside the slide groove 103, and a through hole 402 is opened in the middle of each slider 401. Each through hole 402 is respectively interlaced with the limiting support rod 106 and the driving support rod 107. An expansion block 403 is integrally provided on one side of one slider 401, and a second motor 404 is fixedly installed on one side of the expansion block 403. The infrared sensor 8 is used to control the start and stop of the second motor 404;

[0047] A displacement groove 4011 is formed inside one of the sliders 401, and sliding blocks 405 are movably mounted on both sides of the displacement groove 4011. An adjusting thread 4051 is provided on the surface of one of the sliding blocks 405, and a positioning rod 4052 is provided on the surface of the other sliding block 405.

[0048] Two movable slots 406 are defined within the slider 401 and the expansion block 403. A movable plate 407 is movably disposed within the two movable slots 406. A threaded rod 4041 is fixedly mounted to the output end of the second motor 404. Threaded holes 4071 are formed throughout the movable plate 407, each of which is threadedly engaged with the threaded rod 4041. To adjust the height of the single-layer planting frame 3, the second motor 404 can be started and stopped by the infrared sensor 8. By starting the second motor 404, the threaded rod 4041 rotates, and the threaded engagement of the threaded holes 4071 pushes the two movable plates 407 to move within the movable slots 406, causing the positions of the two sliding blocks 405 to change, causing one of the sliding blocks 405 to engage with the drive support rod 107.

[0049] In the specific configuration, the shaft of the driving support rod 107 is provided with a mating thread 1074, and a plurality of positioning slots 1075 are opened on one side of the shaft of the driving support rod 107. The mating thread 1074 is threadedly engaged with the adjustment thread 4051, and the positioning slots 1075 are interlaced with the positioning rod 4052. The mating thread 1074 and the adjustment thread 4051 are mated by the adjustment thread 4051, and the height of the slider 401 is adjusted by rotating the driving support rod 107, thereby achieving the height adjustment of the planting frame 3.

[0050] After the sliding block 405 is switched by the second motor 404, the positioning slot 1075 is interlaced with the positioning rod 4052, thereby locking the rotation of the current driving support rod 107, and then completing the height adjustment of the planting frame 3. Subsequently, under the action of the first protrusion 10 and the second protrusion 11, the lower end driving support rod 107 will not affect the fixation of the upper end driving support rod 107 when rotating, thereby realizing the height adjustment of the single-layer planting frame 3.

[0051] It can be understood that in the present application, the fill light assembly 5 includes a plurality of mounting seats 501, the mounting seats 501 are fixedly mounted on the lower surface of the upper second support 102, and a plurality of fill light tubes 502 are fixedly mounted inside the mounting seats 501;

[0052] An auxiliary roller 504 is rotatably mounted between two first pillars 101, and a transmission roller 505 is rotatably mounted between the other two first pillars 101. A shielding cloth 503 is provided between the transmission roller 505 and the auxiliary roller 504. The shielding cloth 503 is made of a semi-transparent material and a transparent material and is distinguished from each other.

[0053] A transmission groove 108 is opened on the inner upper side of one of the first pillars 101, and the second bevel gear 1073 is fixedly installed on the rod body of the driving support rod 107 located inside the transmission groove 108, and the first bevel gear 5051 is fixedly installed on the rod body of the transmission roller 505 located inside the transmission groove 108. The first bevel gear 5051 and the second bevel gear 1073 are engaged for transmission.

[0054] The upper surface of the upper second pillar 102 is provided with a docking seat 105 , and the lower surface of the lower second pillar 102 is provided with a docking slot 104 . Several bracket bodies 1 are docked together through the docking slot 104 and the docking seat 105 .

[0055] The working principle of this automatic light-filling planting rack for hydroponic vegetables:

[0056] When in use, the planting frame 3 is first set to the bottom by default, so that there is space at the top for arranging vegetables. After the arrangement is completed, the first motor 6 is started to drive the multiple driving rods 107, wherein the sliding block 405 with the adjustment thread 4051 is fitted with the driving rod 107 by default. Then, under the drive of the first motor 6, the multiple planting frames 3 are driven to perform preliminary height adjustment, and then the fill light tube 502 is started to fill light on the vegetables below.

[0057] During the vegetable hydroponic culture process, the vegetables will grow upwards, and the height of the slide 9 on the slide rail 7 is adjusted to realize the setting of the detection position of the infrared sensor 8. Then the infrared sensor 8 is used to detect the current position. When the vegetables are detected passing by, their data are counted. When the vegetables on multiple planting racks grow too high, the first motor 6 and the connecting component 4 are started to adjust the spacing of each planting frame 3 from top to bottom. The above is the condition setting during adjustment;

[0058] When adjusting the upper end, the first motor 6 is started to drive the driving support rod 107 to rotate, and the height of the uppermost planting frame 3 can be adjusted by using the matching thread 1074 and the adjusting thread 4051. Then, in order to fix the current height of the planting frame 3, the second motor 404 is started, and the threaded rod 4041 is driven to rotate by the second motor 404, and the two movable plates 407 are pushed to move inside the movable groove 406 under the threaded cooperation of the threaded hole 4071, so that the positioning slot 1075 and the positioning rod 4052 are interlaced and matched, thereby completing the height fixing of the uppermost planting frame 3;

[0059] Then, the above process is repeated when adjusting the next layer, and the spacing adjustment of each layer is completed from top to bottom in turn, completing the function of automatically adjusting the fill light effect. In order to prevent the driving support rod 107 at the upper end from rotating again after the adjustment is completed, the driving support rod 107 at the lower end is rotated. When the upper end is locked, the support spring 12 is used to contract the second protrusion 11, so that the first protrusion 10 and the second protrusion 11 of the current layer are separated, and the driving support rod 107 locked at the upper end does not rotate, thereby ensuring the height of the planting frame 3;

[0060] The vegetables in the planting frame 3 are supplemented with light by the supplementary light tube 502. In order to further adjust the supplementary light effect to prevent excessive supplementary light to the vegetables even after the spacing is maximum, the support rod 107 is driven to rotate so that the first bevel gear 5051 and the second bevel gear 1073 are engaged and transmitted, thereby driving the transmission roller 505 to rotate. Subsequently, the translucent or transparent surface of the shielding cloth 503 is adjusted under the rotation of the transmission roller 505. The pre-set setting of the shielding cloth 503 can be used to perform corresponding supplementary light according to the variety of vegetables.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
