Description

Technical Field

[0001] This invention relates to the field of garden technology, specifically to a plant cultivation rack. Background Technology

[0002] When cultivating green plant seedlings, the potted plants need to be placed outdoors to receive sunlight so that the seedlings can grow. However, when cultivating green plants, windy and rainy weather is often encountered. When watering or rainwater is poured on the soil surface, the soil gaps become filled with water and soften, which reduces the connection between the green plant and the soil. Since green plant seedlings have few roots, they can only rely on the hardness of the soil itself to hold them in place. When exposed to wind, the green plant seedlings are easily blown over, and the roots may be pulled out, thus affecting the cultivation quality.

[0003] Therefore, a plant cultivation rack is needed to solve the problem that plant seedlings are easily blown over. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a plant cultivation rack that replenishes water from below the soil by evaporating water in the irrigation area, while also separating rainwater from the soil surface to prevent the connection between the soil above and the plants from weakening, thus reducing the probability of the plants being blown over.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a green plant cultivation rack includes a support, an inner pot, and a cover plate. The outer surface of the support is provided with a plurality of outer pots distributed vertically. The inner pot is disposed on the inner wall of the outer pot and forms an evaporation irrigation area between the two. The outer surface of the support is also provided with a control component. When there is rainwater in the outer pot, the outer pot moves vertically and drives the cover plate to slide upward above the outer pot through the control component. An adjustment component is provided at the opening of the upper outer pot. The adjustment component uses the movement of the cover plate to drive the upper inner pot to move toward the inner cavity of the upper outer pot.

[0006] By adopting the above technical solution, the evaporation irrigation area formed between the outer and inner pots is utilized, and the water in the area is infiltrated into the soil from the bottom as steam to replenish moisture. When it rains, the control component moves the cover plate to the top of the outer pots and covers multiple outer pots, achieving the effect of blocking rain and wind. This prevents excessive rainwater from reducing the connection strength between the soil and the green plants, and also prevents the green plants from being blown over by strong winds. Furthermore, the adjustment component moves the inner pot into the inner cavity of the outer pot to prevent the green plants from being in too high a position and being subjected to strong winds, further reducing the probability of the green plants tipping over.

[0007] The invention is further configured such that: the upper inner basin is connected to the inner wall of the upper outer basin by an adjusting component and moves around the axis of the adjusting component; the lower inner basin is fixedly connected to the inner wall of the lower outer basin; and there is a gap between the inner basin and the side wall of the outer basin; water flows into the bottom of the inner cavity of the inner basin from the gap between the outer basin and the side wall of the inner basin and forms an evaporation irrigation area between them; and the side wall of the outer basin is provided with a through hole.

[0008] By adopting the above technical solution, the inner basin is supported by the control components. When rainwater enters the inner basin, the rainwater will flow from the gap between the outer basin and the inner basin to the bottom of the inner basin. The weight of the outer basin increases and causes the outer basin to move downward. Then, the inner basin is driven deeper into the outer basin by the adjustment components, which further reduces the height of the green plants and reduces the wind force on the green plants.

[0009] The present invention is further configured such that: two symmetrically distributed first sliding grooves are provided on the outer surface of the bracket near the outer basin; a first sliding block is fixedly connected to the outer surface of the upper outer basin near the bracket and slidably connected to the inner wall of the first sliding groove; and the lower end of the outer basin is poweredly connected to the control component.

[0010] By adopting the above technical solution, the first sliding groove is used to limit the movement trajectory of the first sliding block and the outer basin, and the outer basin is supported by the control component. When the weight of the outer basin increases, the control component transmits the movement power of the outer basin to the cover plate.

[0011] The invention is further configured such that: the control component includes a conversion rod and a second sliding block; the bracket has a second sliding groove slidably connected to the second sliding block on its outer surface near the outer basin; a rotating shaft is fixedly connected to one end of the second sliding block away from the second sliding groove; a rotating groove is provided through one end of the conversion rod away from the second sliding block, abutting against the two rotating shafts; and an adjustment block is rotatably connected to the other end of the conversion rod; an adjustment groove is provided at the lower end of the outer basin along the line connecting the two outer basins; the adjustment block is slidably connected to the inner wall of the adjustment groove; and two symmetrically distributed intermediate shafts are fixedly connected to the outer surface of the bracket located below the outer basin, and the intermediate shafts are rotatably connected to the middle position of the conversion rod.

[0012] By adopting the above technical solution, when the outer basin moves downward, the adjusting block presses one end of the conversion rod downward, while the other end of the conversion rod is restricted by the intermediate shaft and moves upward, which at the same time drives the second sliding block to move upward. When the adjusting block moves downward about the intermediate shaft, it is restricted by the adjusting groove and slides, ensuring the connection between the adjusting block and the outer basin.

[0013] The present invention is further configured such that: the control component further includes a connecting rope; the outer surface of the second sliding block is fixedly connected to the inner wall of the second sliding groove by a spring; the lower ends of the two symmetrically distributed baffles are fixedly connected by a connecting rope; and the upper end of the second sliding block is fixedly connected to the middle position of the connecting rope.

[0014] By adopting the above technical solution, the spring provides a downward pulling force to the second sliding block. The pulling force is then converted into an upward supporting force for the outer basin through the conversion rod and the intermediate shaft. When the water in the outer basin increases, the outer basin is affected by gravity and presses one end of the conversion rod downward, causing the second sliding block to move upward and stretch the spring. The second sliding block drives the cover plate to move upward through the connecting rope and covers the outer basin, completing the conversion between the downward movement of the outer basin and the upward movement of the cover plate. The equipment can be operated without a power source, reducing costs.

[0015] The present invention is further configured such that: the adjusting component includes a rotating block, an adjusting shaft, and an adjusting rod; the inner side wall of the baffle near the outer basin is provided with a connecting groove that is slidably connected to the rotating block; the adjusting shaft is rotatably connected to the edge of the opening on the outer basin, and the adjusting shaft is fixedly connected to the connecting groove; an adjusting rod is fixedly connected to each end of the adjusting shaft; and the other end of the adjusting rod is rotatably connected to the upper end face of the opening on the inner basin.

[0016] By adopting the above technical solution, the connection between the rotating block and the connecting groove allows the cover to rotate around the rotating block's axis of rotation when it moves upward, thereby moving the cover above the outer pot to cover it. When the cover moves the rotating block upward, the other end of the control rod moves the inner pot into the outer pot cavity, thus completing the concealment of the green plants and reducing the impact of wind.

[0017] The invention is further configured such that: the two baffles are located between the two outer basins above and are of inferior arc, and they partially enclose the outer basins, and the surface of the baffles is provided with a receiving groove through which the conversion rod passes.

[0018] By adopting the above technical solution, the curved structure of the baffle plate and its upward movement restricted by the opening at the top of the inner basin allow the baffle plate to rotate relative to the connection between the control shaft and the inner basin when it rises. This allows the baffle plate to be moved from the side of the outer basin to the top of the outer basin and can be tilted downwards from the other direction, reducing the space occupied by the equipment.

[0019] The invention is further configured such that: a cotton cloth cover made of cotton material is fixedly connected to the opening of the inner pot, and a hole for the growth of green plants is opened at the center of the cotton cloth cover.

[0020] By adopting the above technical solution, the cotton cloth cover is used to prevent rainwater from impacting the soil surface. At the same time, it can isolate more rainwater on the outside of the soil and allow it to flow into the bottom of the outer pot from the gap between the outer pot and the inner pot, thus preventing the soil from being subjected to too much water impact and reducing the connection strength with the green seedlings.

[0021] The present invention is further configured such that: a cotton cloth block extending into the inner cavity of the inner basin is provided through one end of the inner basin near the bottom wall of the outer basin, the cotton cloth block being made of cotton cloth material and having an upwardly recessed permeation hole at its lower end.

[0022] By adopting the above technical solution, the cotton cloth at the bottom of the inner pot absorbs the water evaporated from the bottom of the outer pot and replenishes the water from below the soil, thereby increasing the connection strength between the green seedlings and the soil.

[0023] The invention is further configured such that the outer basin is made of transparent plastic material and its bottom wall is black.

[0024] By adopting the above technical solution, the transparency of the outer pot allows sunlight to reach the bottom of the outer pot, thereby increasing the evaporation rate of water in the evaporation irrigation area and replenishing the soil moisture.

[0025] In summary, the present invention has the following beneficial effects:

[0026] First, use a cotton cloth to cover the soil to prevent excessive rainwater from impacting the soil surface and collect the rainwater at the bottom of the outer pot. Then, use sunlight to increase the evaporation rate of water at the bottom of the outer pot, providing moisture to the soil below. This replenishes the soil with water without affecting the connection between the soil surface and the seedlings, reducing the impact of harsh environments on plant cultivation.

[0027] Secondly, the added weight inside the outer pot drives the outer pot to descend, and then the conversion rod, the second sliding block, and the connecting rope drive the cover plate to rise. While reducing the height of the outer pot and reducing the impact of natural wind on the outer pot, it can also drive the cover plate to rise and cover the outer pot, further blocking the natural wind and preventing the green seedlings from being blown over by strong winds.

[0028] Third, by using the control rod and control shaft, when the first sliding groove rises, it can also drive the upper inner pot to move into the inner cavity of the outer pot. The outer pot protects the green seedlings and moves the upper outer pot closer to the lower outer pot. This not only reduces the wind-exposed area of ​​the equipment, but also uses the upper outer pot to further shield the green plants in the lower outer pot, increasing the wind protection effect of the green seedlings in the entire equipment.

[0037] The present invention will now be described in detail with reference to the accompanying drawings of the embodiments thereof.

[0038] Example:

[0039] This type of plant cultivation rack, such as Figures 1 to 4As shown, the system includes a support 11, an inner basin 15, and a baffle 21. Multiple outer basins 14 are arranged vertically on the outer surface of the support 11. The inner basin 15 is disposed on the inner wall of the outer basins 14, forming an evaporation irrigation area between them. A control component is also provided on the outer surface of the support 11. When rainwater is present in the outer basins 14, the outer basins 14 move vertically, and the control component drives the baffle 21 to slide upwards above the outer basins 14. An adjustment component is provided at the opening of the upper outer basin 14. The adjustment component uses the movement of the baffle 21 to move the upper inner basin 15 towards the inner cavity of the upper outer basin 14. The upper inner basin 15 is connected to the inner wall of the upper outer basin 14 via the adjustment component. The position is moved around the axis of the adjusting component. The inner wall of the lower inner basin 15 is fixedly connected to the inner wall of the lower outer basin 14, and there is a gap between the side walls of the inner basin 15 and the outer basin 14. Water flows into the bottom of the inner cavity of the inner basin 15 from the gap between the side walls of the outer basin 14 and the inner basin 15 and forms an evaporation and irrigation area between them. The side wall of the outer basin 14 is provided with a through hole 29. Two first sliding grooves 12 are symmetrically distributed on the outer surface of the support 11 near the outer basin 14. The upper outer basin 14 is fixedly connected to the outer surface of the support 11 near the outer surface of the support 11 with a first sliding block 18 that is slidably connected to the inner wall of the first sliding groove 12. The lower end of the outer basin 14 is poweredly connected to the control component.

[0040] like Figures 3 to 5 As shown, the control component includes a conversion rod 25 and a second sliding block 24. A second sliding groove 13, slidably connected to the second sliding block 24, is provided on the outer surface of the bracket 11 near the outer basin 14. A rotating shaft 35 is fixedly connected to one end of the second sliding block 24 away from the second sliding groove 13. A rotating groove 27, abutting against the two rotating shafts 35, is provided through one end of the conversion rod 25 away from the second sliding block 24. An adjustment block 31 is rotatably connected to the other end of the conversion rod 25. An adjustment groove 30, along the line connecting the two outer basins 14, is provided at the lower end of the outer basin 14. The adjusting block 31 is slidably connected to the inner wall of the adjusting groove 30, and two symmetrically distributed intermediate shafts 26 are fixedly connected to the outer surface of the bracket 11 located below the outer basin 14. The intermediate shafts 26 are rotatably connected to the middle position of the conversion rod 25. The control component also includes a connecting rope 32. The outer surface of the second sliding block 24 is fixedly connected to the inner wall of the second sliding groove 13 by a spring 28. The lower ends of the two symmetrically distributed baffles 21 are fixedly connected by a connecting rope 32. The upper end of the second sliding block 24 is fixedly connected to the middle position of the connecting rope 32.

[0041] like Figure 2 and Figure 6As shown, the adjustment component includes a rotating block 33, an adjustment shaft 20, and an adjustment rod 19. The inner side wall of the cover plate 21 near the outer basin 14 has a connecting groove 23 that is slidably connected to the rotating block 33. The adjustment shaft 20 is rotatably connected to the edge of the opening on the outer basin 14, and the adjustment shaft 20 is fixedly connected to the connecting groove 23. An adjustment rod 19 is fixedly connected to each end of the adjustment shaft 20, and the other end of the adjustment rod 19 is rotatably connected to the upper end face of the opening on the inner basin 15.

[0042] like Figure 5 As shown, the two baffles 21 are located between the two outer basins 14 above and are of inferior arc, and they partially enclose the outer basins 14. The surface of the baffles 21 is provided with a receiving groove 22 through which the conversion rod 25 passes.

[0043] like Figure 2 As shown, a cotton cloth cover 17 made of cotton cloth is fixedly connected to the opening of the inner basin 15, and a hole for green plants to grow is opened in the center of the cotton cloth cover 17. A cotton cloth block 16 extending into the inner cavity of the inner basin 15 is provided through one end of the inner basin 15 near the bottom wall of the outer basin 14. The cotton cloth block 16 is made of cotton cloth and has an upwardly recessed permeation hole 34 at its lower end. The outer basin 14 is made of transparent plastic material and its bottom wall is black.

[0044] The sliding connection between the second sliding block 24 and the second sliding groove 13 restricts the movement trajectory of the second sliding block 24 on the support 11. The connection between the first sliding block 18 and the first sliding groove 12 restricts the movement trajectory of the first sliding block 18 and the upper outer basin 14. The second sliding block 24 and the upper outer basin 14 are connected by a conversion rod 25 and an adjusting block 31. When the outer basin 14 descends, the adjusting block 31 not only moves downwards but also slides horizontally along the trajectory of the adjusting groove 30, providing support. The lower outer basin 14 is directly fixed to the surface of the support 11. In windy and rainy weather, when rainwater falls onto the inner basin 15 inside the outer basin 14, the cotton cloth cover 17 prevents excessive rainwater from directly eroding the surface of the soil inside the inner basin 15, thus preventing... The contact between soil and rainwater reduces adhesion, increasing the bond strength between the seedlings and the soil, preventing the seedlings from being blown over by the wind. Simultaneously, the cotton cover 17 separates a significant amount of rainwater, allowing it to flow along the gap between the outer pot 14 and the inner pot 15 to the bottom of the outer pot 14, thus increasing the overall weight of the outer pot 14. The outer pot 14 presses one end of the conversion rod 25 downwards, while the middle section of the conversion rod 25 is rotatably connected to the intermediate shaft 26. The conversion rod 25 passes through the receiving groove 22 on the cover plate 21 and slides along it, ensuring that the cover plate 21 does not interfere with the conversion rod 25 when in a lower position. The intermediate shaft 26 is fixedly connected to the outer surface of the support 11, causing the conversion rod 25 to move in a tilting motion, with its other end moving upwards. The conversion rod 25 carries... When the second sliding block 24 moves upward, the other end of the conversion rod 25 rotates along the axis of the intermediate shaft 26, and the rotating shaft 35 slides in the rotating groove 27, completing the process of the two outer basins 14 moving the second sliding block 24 upward. The second sliding block 24 drives the lower end of the cover plate 21 to move upward from the side of the outer basin 14 through the connecting rope 32. The spring 28 connects the lower end of the second sliding block 24 to the bottom wall of the second sliding groove 13. The spring 28 uses its own elasticity and supports the outer basin 14 through the second sliding block 24, the conversion rod 25, and the adjusting block 31 to prevent the outer basin 14 from failing to return to its original position when its mass decreases. The adjusting shaft 20 is rotatably connected to the opening of the outer basin 14, and a connecting groove that is slidably connected to the rotating block 33 is fixedly connected to the adjusting shaft 20. 23. When the baffle 21 rises, it is restricted by the connecting groove 23 and rotates around the axis of the adjusting shaft 20. This causes the baffle 21 to move from the side of the outer basin 14 to the top, thus covering the outer basin 14. The baffle 21 is curved, and its structure of partially enclosing the outer basin 14 prevents it from extending too far during rising and rotating, reducing wind resistance and increasing practicality. When the upper outer basin 14 descends, it simultaneously causes the baffle 21 to rise and rotate. The first sliding groove 12 on the baffle 21 drives the adjusting shaft 20 to rotate via the rotating block 33. Simultaneously, the adjusting shaft 20 drives the adjusting rod 19 to rotate around the axis of the adjusting shaft 20. The other end of the adjusting rod 19 is rotatably connected to the opening on the inner basin 15.Meanwhile, the other end of the control rod 19 and the rotating block 33 are located on both sides of the control shaft 20 and move in opposite directions. That is, the control rod 19 drives the inner pot 15 to move downwards, while the movement between the outer pot 14 and the inner pot 15 provides the inner pot 15 with a horizontal movement stroke, preventing the inner pot 15 from being stuck by the outer pot 14 and unable to move downwards. This allows the green seedlings planted in the inner pot 15 to retract into the outer pot 14 during windy and rainy weather, ensuring that the green plants will not be blown over by strong winds. Furthermore, the downward movement of the outer pot 14 will reduce the height of the green plants and allow them to contact the outer pot 14 below, enhancing the equipment's ability to resist strong winds. At the same time, the side wall of the outer pot 14 is provided with a through hole 29 for draining excess water from the bottom of the outer pot 14, preventing rainwater from overflowing the inner pot 15 and causing the soil surface in the inner pot 15 to become damp. The layer of moisture increases the connection between the plants and the soil. When watering is needed, water is injected into the bottom of the outer pot 14 through the through-hole 29. The transparent outer pot 14 allows sunlight to fall onto the water at the bottom. Utilizing the photothermal effect and the black color of the bottom wall of the outer pot 14, light energy is converted into heat energy, causing the water at the bottom of the outer pot 14 to evaporate and rise. The water vapor is absorbed by the cotton cloth blocks 16, and the permeation holes 34 increase the absorption efficiency of the cotton cloth blocks 16 for water vapor from the air. The water is then transferred to the soil inside the inner pot 15, watering the soil from below, minimizing the moisture on the soil surface and increasing the connection between the soil and the seedlings. Multiple cotton cloth blocks 16 maximize the transfer of steam water into the soil.
