TECHNICAL FIELD

[0002] A plant growth box is a device that simulates the growth environment of plants in a sealed container, and is commonly used for cultivating plant seedlings and conducting plant growth experiments. Its working principle is mainly to simulate various elements in the natural environment, such as temperature, humidity, light, and gas composition, to create suitable conditions for plant growth.
[0003] The existing plant growth box has a big shortcoming in simulating light. The light used for simulation is relatively single, so the light spectrum combination formed by it is also relatively single. Different plants and different growth stages of the same plant have different light requirements. Therefore, a single light spectrum combination cannot effectively and closely simulate the plant growth spectrum parameters that meet the corresponding requirements, and its applicability is relatively low. At the same time, in the process of cultivation, plants are often placed in a close manner on the same platform. However, as the plants grow and develop, the space occupied by a single plant often increases, especially the upper part of the plant containing leaves, which causes the plants to be shaded by branches and leaves. Shading makes it difficult to observe the growth conditions of plants in detail, and also causes uneven distribution of nutrients, resulting in poor cultivation effect and inaccurate cultivation data.

Referring to Figure 13 , the spraying unit 3 includes two groups of main shafts 31 coaxially arranged on the inner wall of the box body 1, a driving groove one 311 and a driving groove two 312 equally arranged on each group of main shafts 31, a moving nozzle 32 arranged in the driving groove one 311 and the driving groove two 312, a connecting shaft 33 connected between the two groups of main shafts 31, and a fixed nozzle 34 located on the side of the connecting shaft 33, the moving nozzle 32 and the fixed nozzle 34 have the same structure, the fixed nozzle 34 is fixedly connected at the middle position, there are four groups of moving nozzles 32 on the two groups of main shafts 31, and the distance between every two of the four groups of moving nozzles 32 and the fixed nozzle 34 is the same in the initial state.
[0034] Further, the cross section of the partition plate 12 is triangular, the lamp plate 13 comprises white light wave, blue light wave, red light wave and far red light wave four-color LED light source, and the light intensity of each color light source can be independently adjusted. The triangular partition plate 12 can facilitate water condensation and downward discharge. The white light wavelength is 400-700NM, the red light wavelength is 660NM, the blue light wavelength is 460NM, the far red light wavelength is 730NM, the high light intensity can reach 1500MMOL / M2 / S, and the four-color light source can be arranged in 100 4 different spectral combinations to adjust the most suitable spectral parameters for plant growth and meet more use requirements. Meanwhile, the lamp bead positions on the lamp plate 13 are scientifically laid out to ensure that the light uniformity at the same horizontal position is less than 5%.
[0035] Further, referring to Figure 7 , the support 21 is arranged in a cross structure in the cultivation bin 11, and a limiting groove 211 is arranged on each group of branches of the cross structure. The two sides of the support 21 are provided with a reinforcing rod 212 connected with the box body 1. The limiting groove 211 is used for limiting the moving direction of the pushing component 23 and the moving component 24. The reinforcing rod 212 is used for reinforcing the connection stability between the support 21 and the box body 1.
[0036] Referring to Figure 8 , the driving component 22 comprises a rotating disc 221 rotatably connected to the center of the support 21. A group of tray threes 27 are arranged at the top end of the rotating disc 221. Two groups of upper connecting ears 222 are horizontally and symmetrically arranged on the left and right sides of the rotating disc 221 and are directed upward. Two groups of lower connecting ears 223 are vertically and symmetrically arranged on the front and rear sides of the rotating disc 221 and are directed downward. A bevel gear one 224 is arranged below the rotating disc 221 and penetrates through the support 21 downward. The driving component 22 can drive the upper pushing rod 231 and the upper pushing rod 231 to move through the upper connecting ears 222 and the lower connecting ears 223, respectively. The upper connecting ears 222 and the lower connecting ears 223 are arranged in a staggered manner, so that the upper connecting ears 222 and the lower connecting ears 223 connected thereto are not at the same height, thereby avoiding affecting the rotation of the driving component 22.
[0037] Referring to Figure 9The pushing component 23 comprises two groups of upper pushing rods 231 distributed horizontally, and the inner ends of each group of upper pushing rods 231 are respectively connected with the outer ends of a group of upper connecting ears 222 in rotation, and two groups of lower pushing rods 232 distributed vertically, and the inner ends of each group of lower pushing rods 232 are respectively connected with the outer ends of a group of lower connecting ears 223 in rotation. The upper pushing rods 231 are in the shape of the number "7" as a whole, and the lower end of the "7" is the inner end of the upper pushing rod 231. The upper pushing rods 231 and the lower pushing rods 232 are the same in structure. The two groups of upper pushing rods 231 are connected on the two sides of the driving component 22 in staggered manner. When the driving component 22 rotates, it drives the two groups of upper pushing rods 231 to move through the upper connecting ears 222. The lower pushing rods 232 are driven by the driving component 22 in the same way as the upper pushing rods 231. The structure of the "7" shape can avoid the two groups of upper pushing rods 231 or the upper pushing rods 231 from overlapping on the same straight line, causing mutual hindrance.
[0038] In the above description, the reference Figure 6 and Figure 7 The moving component 24 comprises two groups of upper sliding rods 241 arranged horizontally in parallel, and the axial positions of each group of upper sliding rods 241 are provided with vertical rods 2411, and the upper and lower ends of the vertical rods 2411 extend to the outer ends of the upper pushing rods 231 and the limiting grooves 211 respectively. Each group of vertical rods 2411 is provided with a group of trays 25 at the top end. The moving component 24 also comprises two groups of lower sliding rods 242 arranged vertically in parallel, and the axial positions of each group of lower sliding rods 242 are provided with vertical rods 2421, and the upper and lower ends of the vertical rods 2421 extend to the outer ends of the lower pushing rods 232 and the limiting grooves 211 respectively. Each group of vertical rods 2421 is provided with a group of trays 25 at the top end. The upper sliding rods 241 are connected together with the upper pushing rods 231 through the vertical rods 2411. Therefore, the upper pushing rods 231 can drive the upper sliding rods 241 to slide horizontally along the horizontal limiting grooves 211 through the vertical rods 2411. Since the two groups of upper sliding rods 241 are connected with the two groups of upper pushing rods 231 respectively, the two groups of upper sliding rods 241 can move in opposite directions under the driving of the two groups of upper pushing rods 231. The lower sliding rods 242 are connected with the lower pushing rods 232 in the same way as the upper sliding rods 241. Therefore, the two groups of lower sliding rods 242 can also move vertically in opposite directions under the driving of the lower pushing rods 232.
[0039] Further, in the above description, the reference Figure 10The upper slide bar 241 is located above the lower slide bar 242, and a group of trays 26 are provided at the junction of each group of lower slide bars 242 and the upper slide bar 241. The lower part of the tray 26 is staggered between the slider 1 261 and the slider 2 262, and the slider 1 261 and the slider 2 262 are respectively sleeved on the upper slide bar 241 and the lower slide bar 242. The height staggered manner of the upper slide bar 241 and the lower slide bar 242 can prevent the two from interfering with each other. When the upper slide bar 241 moves vertically, the upper slide bar 241 can be moved by the slider The first 261 pushes the tray 26 to move vertically as a whole, and the tray 26 will drive the slider 262 to slide along the lower slide bar 242. Conversely, when the lower slide bar 242 moves horizontally, the lower slide bar 242 can push the tray 26 to move horizontally as a whole through the slider 262, and the tray 26 will drive the slider 1 261 to slide along the upper slide bar 241. Therefore, the tray 26 can always be maintained at the intersection of the upper slide bar 241 and the lower slide bar 242 through the slider 1 261 and the slider 2 262.
[0040] Combine Figure 11 and Figure 12 In the early stage of plant growth, the space occupied by the plant seedlings is small, so the supporting unit 2 is in a retracted state at this time. At this time, the multiple groups of trays 1 25, trays 2 26 and trays 3 27 provided on the supporting unit 2 are arranged in a small nine-square grid pattern inside the cultivation chamber 11, and the distance between each adjacent group of trays 1 25, trays 2 26 and trays 3 27 is the same. As the plants grow and develop, the space required to be occupied by each plant increases. According to the actual demand for the space required to be occupied by each plant, the driving component 22 drives the upper push rod 231 and the lower push rod 232 to move synchronously by rotating. The upper push rod 231 and the lower push rod 232 will be driven by the driving component 22 to push the upper slide bar 241 and the lower slide bar 242 respectively. The lower slide bar 242 moves horizontally and vertically along the limit groove 211. The moving upper slide bar 241 and the lower slide bar 242 will push the multiple groups of trays 2 26 and tray 1 25 to expand outward with tray 3 27 as the center, thereby increasing the distance between each adjacent group of trays 1 25, tray 2 26 and tray 3 27. At this time, the nine-square grid composed of the multiple groups of trays 1 25, tray 2 26 and tray 3 27 will also be enlarged proportionally, thereby achieving a proportional adjustment method to adjust the distance between the plants, avoid occlusion between the plants, and ensure that each plant has a suitable growth space, so that the plants can grow and develop normally, ensure the cultivation effect, and facilitate observation and recording by the staff.
[0041] Further, refer to Figure 1 and Figure 13The inner wall of the box body 1 is provided with an installation groove 16 corresponding to the spraying unit 3, the side opening section of the installation groove 16 is a tapered structure, the main shaft 31 is arranged in the installation groove 16, the driving groove one 311 and the driving groove two 312 are both spiral arc structures with 0.5 turns, the length ratio of the two is 1:2, a group of moving nozzles 32 are connected in the driving groove one 311 and the driving groove two 312, when the main shaft 31 drives the two to rotate, the two push the corresponding moving nozzles 32 to move, based on the length ratio, the moving distance of the moving nozzles 32 installed in the two is also in the same proportion when driven, so that the purpose of adjusting the distance between the two groups of moving nozzles 32 in equal proportion is realized.
[0042] Further, referring to Figure 13 The connecting shaft 33 is provided with a bevel gear two 331, the inner end of the moving nozzle 32 is provided with a limiting block 321 matched with the tapered section opening of the installation groove 16, and an extension shaft 322 is arranged at the outer end of the limiting block 321 and extends into the bevel gear two 331, the connecting shaft 33 is an industrial ultrasonic atomizing nozzle, the tapered limiting block 321 can make the moving nozzle 32 slide smoothly in the installation groove 16 without being separated from the installation groove 16, and at the same time, the moving nozzle 32 is limited by the installation groove 16 through the limiting block 321, and the extension shaft 322 extends into the driving groove one 311, so that the whole moving nozzle 32 can be affected by the main shaft 31, when the driving groove one 311 rotates with the main shaft 31, the whole moving nozzle 32 can be driven by the extension shaft 322 to move horizontally along the installation groove 16.
[0043] Combined with Figure 14, the spraying unit 3 in actual use, when the plant is in the seedling state, the support unit 2 is in the contracted state as a whole, at this time the space occupied by the plant is smaller and more concentrated, at this time the plurality of groups of mobile spray heads 32 and fixed spray heads 34 on the main shaft 31 are concentrated in the relatively central position of the spraying unit 3 as a whole, at this time the spraying range of the spraying unit 3 as a whole is smaller and concentrated in the range corresponding to the seedling plant, so that the water and nutrients sprayed by the mobile spray head 32 are accurately sprayed on the plant, avoiding spraying to other blank areas, causing nutrient waste phenomenon, and when the support unit 2 adjusts the distance between the plants according to the growth of the plants, the plant coverage range increases, at this time the main shaft 31 is driven by the driving unit 4 to rotate, the rotation of the main shaft 31 drives the respective mobile spray heads 32 to slide horizontally along the installation groove 16 through the driving groove one 311 and the driving groove two 312, thereby increasing the distance between each adjacent two groups of mobile spray heads 32, and also expanding the spraying range covered by the spraying unit 3 as a whole, at this time the spraying unit 3 with expanded spraying range can meet the spraying operation of the same large range of plant coverage area, further, the adjustment range of the driving mobile spray head 32 of the spraying unit 3 and the overall spraying range is proportional to the plant distance adjustment range of the support unit 2, and both are driven synchronously by the driving unit 4, so the spraying unit 3 can ensure that under the circumstances, it can adjust the appropriate spraying range following the support unit 2, so that its spraying range follows the plant range to adjust synchronously, ensuring that the plant can fully supplement water during growth, and ensuring the normal growth and development of the plant.
[0044] Further, referring to Figure 2 , the driving unit 4 includes a rotating shaft 41 vertically arranged inside the box 1, two groups of auxiliary shafts 42 transversely arranged on the side of the rotating shaft 41, and each group of auxiliary shafts 42 extends to the lower side of each group of support units 2, and a motor 43 arranged at the end of the rotating shaft 41, the rotating shaft 41 and the auxiliary shaft 42 are provided with matching bevel gears three 411 and bevel gears five 421, the outer end of the auxiliary shaft 42 is provided with a bevel gear six 422 engaged with the bevel gear one 224, and the rotating shaft 41 is provided with a bevel gear four 412 engaged with the bevel gear two 331 at the top end, so that the driving unit 4 can drive the support unit 2 and the spraying unit 3 to adjust the plant distance and the spraying range respectively through the rotating shaft 41 and the auxiliary shaft 42, so that the operation of the two can be synchronized, without the need for additional adjustment work, making the device more flexible.
