Description

Technical Field

[0001] This invention relates to the field of landscape planting technology, and more specifically, to a compact, three-dimensional planting rack for landscapes. Background Technology

[0002] With the acceleration of urbanization and the increasing scarcity of land resources, three-dimensional and intensive landscaping planting models are gradually becoming the development trend of urban greening and home gardening. Traditional flat planting methods occupy a lot of space and cannot meet the greening needs of high-density environments. Although some multi-layer planting racks have been applied in actual scenarios, most of them have fixed structures and cannot flexibly adjust the spatial layout according to the plant's growth stage. This results in excessive space occupation during the seedling stage or insufficient light and ventilation during the growing season, making it difficult to meet the dual needs of compact storage and efficient growth.

[0003] Furthermore, existing vertical planting systems have significant shortcomings in terms of automation and intelligence. They often require manual adjustment or movement of plants layer by layer to optimize lighting conditions, which is cumbersome and inefficient. At the same time, the power transmission and spatial expansion and contraction between the multi-layered structures often interfere with each other, making it difficult to achieve overall synchronous deployment or step-by-step control. In addition, the lack of an integrated irrigation system results in low water resource utilization efficiency.

[0004] Therefore, there is an urgent need for a compact, three-dimensional planting rack that can automatically adjust the spacing between layers and the radial position of planting units, and has synchronous transmission, in order to improve the space utilization and management automation level of garden planting. Summary of the Invention

[0005] The purpose of this invention is to provide a compact, three-dimensional planting rack for gardens, aiming to solve the problems mentioned in the background art.

[0006] This invention is implemented as follows: a compact, three-dimensional planting rack for gardens includes multiple longitudinally distributed support trays, with casters installed at the bottom of the lowest support tray, and also includes:

[0007] Multiple telescopic components are evenly distributed and fixed on the outer circumference between two adjacent bearing plates;

[0008] The planting cylinder has multiple planting cylinders evenly distributed around the upper side of the support plate. Two end blocks are fixed on the lower side of the planting cylinder to the support plate. A screw is rotatably installed between the two end blocks. A moving block is threaded onto the screw and fixedly connected to the bottom of the planting cylinder.

[0009] The guide assembly, wherein the support plate is also equipped with a guide assembly for guiding the movement of the planting cylinder;

[0010] The transmission assembly includes a motor fixed to the uppermost support plate via a motor bracket. An end tube is rotatably mounted in the center of the uppermost support plate, and cascade tubes are rotatably mounted in the center of the remaining support plates. A cascade prism is fixed to the upper end of each cascade tube, and the cascade prism is slidably connected to the adjacent cascade tube above it. The uppermost cascade prism is also slidably connected to the end tube. The output end of the motor is also connected to the upper end of the end tube. A second bevel gear is fixed on both the end tube and the cascade tube, and a first bevel gear that meshes with the second bevel gear is correspondingly mounted on the inner end of the lead screw.

[0011] Optionally, the output shaft, end tube, cascaded prism, and cascaded tube of the motor are all coaxially arranged; multiple motor supports are fixedly distributed around the outer circumference of the motor, and the motor supports are staggered with the planting cylinder, with the end of the motor support away from the motor being fixedly connected to the uppermost support plate.

[0012] Optionally, the guide assembly includes guide rails parallel to both sides of the lead screw. The guide rails have a T-shaped structure, and the lower end of the guide rails is fixed to the bearing plate. A support slider is slidably provided on the guide rails, and the support slider is fixedly connected to the bottom of the planting cylinder.

[0013] Optionally, the planting cylinder adopts an open-top cylindrical structure, with a leak-proof mesh installed on the lower inner side of the planting cylinder, and a support column fixed to the lower side of the leak-proof mesh, the lower end of the support column abutting against the inner bottom of the planting cylinder; a drain pipe with a valve is also installed on the bottom side of the planting cylinder.

[0014] Optionally, it also includes a water replenishment component, which includes a water tank fixed to the bottom of the lowest support plate, a water inlet at the top of the water tank, a water pump installed at the bottom of the water tank, and a water supply pipe connected to the outlet of the water pump. A second annular cavity is also formed on the inner and outer sides of the support plate, and two longitudinally adjacent second annular cavities are connected by a water supply pipe. The water supply pipe is also connected to the second annular cavity of the lowest support plate. A first annular cavity is formed on the upper inner side of the planting tube, and nozzles with downward-sloping inner ends are also circumferentially distributed on the upper part of the planting tube. The nozzles are connected to the first annular cavity, and the first annular cavity is also connected to the second annular cavity of the support plate in the same layer through a water supply pipe.

[0015] Optionally, a first valve and a second valve are respectively installed on the water inlet pipe and the water supply pipe.

[0017] The present invention provides a compact, three-dimensional planting rack for gardens, which has the following beneficial effects:

[0018] The longitudinal, three-dimensional arrangement of multiple support trays facilitates compact, three-dimensional seedling cultivation. Telescopic components allow for the longitudinal separation of these trays, facilitating planting and light exposure in the planting cylinder. The extension and retraction of these components do not affect the power transmission of the drive system. Power is output from the motor to the end tube, and then transmitted through cascaded prisms and tubes for integrated transmission. This, combined with the meshing of the first and second bevel gears, drives all the lead screws, enabling the expansion and contraction of the planting cylinder. Expanding the planting cylinder not only improves stability but also prevents plants within the cylinder from interfering with each other. Furthermore, the elongated shape of the planting cylinder, extending beyond the contour of the support trays, allows for better light exposure. Additionally, a guide component ensures stable and reliable movement of the planting cylinder.

[0019] In summary, this invention achieves automatic expansion / contraction of planting tubes with compact storage and optimized light, and utilizes an integrated transmission system to ensure the stability and efficiency of multi-layer synchronous adjustment.

[0032] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0036] The following is a detailed description, with reference to the accompanying drawings, of a compact, three-dimensional planting rack for gardens according to an embodiment of the present invention.

[0037] Example 1

[0038] like Figure 1-3 As shown in Figure 5, a compact three-dimensional planting rack for gardens is provided in one embodiment of the present invention. It includes multiple longitudinally distributed support plates 2, with casters 1 installed at the bottom of the lowest support plate 2 to facilitate flexible movement of the device. It also includes:

[0039] Telescopic components 4 are evenly distributed and fixed on the outer circumference between two adjacent bearing plates 2; wherein, the telescopic components 4 can be electric telescopic rods, which facilitates intelligent control;

[0040] Planting cylinder 8: Multiple planting cylinders 8 are evenly distributed around the upper side of the support plate 2. Two end blocks 5 are fixed on the lower side of the planting cylinder 8 to the support plate 2. A screw rod 13 is rotatably installed between the two end blocks 5. A moving block 28 is threadedly connected to the screw rod 13. The moving block 28 is fixedly connected to the bottom of the planting cylinder 8.

[0041] The guide assembly is also installed on the support plate 2 for guiding the movement of the planting cylinder 8;

[0042] The transmission assembly includes a motor 12 fixed to the uppermost support plate 2 via a motor bracket 11. An end tube 21 is rotatably mounted in the middle of the uppermost support plate 2, and cascade tubes 18 are rotatably mounted in the middle of the remaining support plates 2. A cascade prism 17 is fixed to the upper end of the cascade tube 18, and the cascade prism 17 is slidably connected to the adjacent cascade tubes 18 above it. The uppermost cascade prism 17 is also slidably connected to the end tube 21. The output end of the motor 12 is also connected to the upper end of the end tube 21. A second bevel gear 25 is fixed on both the end tube 21 and the cascade tubes 18, and a first bevel gear 24 that meshes with the second bevel gear 25 is correspondingly installed on the inner end of the lead screw 13.

[0043] In this embodiment of the invention, the longitudinal three-dimensional arrangement of multiple support plates 2 facilitates compact three-dimensional seedling cultivation. The telescopic component 4 allows the multiple support plates 2 to be longitudinally separated, facilitating planting in the planting cylinder 8 and ensuring adequate light exposure. Furthermore, the extension and retraction of the telescopic component 4 does not affect the power transmission of the transmission assembly. The motor 12 outputs power to the end pipe 21, which then achieves integrated transmission via cascaded prisms 17 and cascaded pipes 18. This, combined with the meshing transmission of the first bevel gear 24 and the second bevel gear 25, drives all the lead screws 13, thereby enabling the expansion and contraction adjustment of the planting cylinder 8. Expanding the planting cylinder 8 not only improves stability but also prevents the plants within it from interfering with each other. The elongation of the planting cylinder 8 from the contour of the support plates 2 allows for better light exposure. In addition, the guide assembly facilitates the stable and reliable movement of the planting cylinder 8.

[0044] In summary, this invention achieves automatic expansion / contraction of the planting tube 8 with compact storage and optimized light, and ensures the stability and efficiency of multi-layer synchronous adjustment by utilizing an integrated transmission system.

[0045] like Figure 1-5As shown, in a preferred embodiment of the present invention, the bottommost cascade tube 18 can be directly rotatably connected to the support plate 2, while the remaining cascade tubes 18 can be installed through the support plate 2, which is beneficial for the cascading of the cascade prisms 17.

[0046] The output shaft, end tube 21, cascaded prism 17 and cascaded tube 18 of the motor 12 are all coaxially arranged. Multiple motor supports 11 are fixedly distributed around the outer circumference of the motor 12. The motor supports 11 are staggered with the planting tube 8. The end of the motor support 11 away from the motor 12 is fixedly connected to the uppermost bearing plate 2, which can stably support the motor 12.

[0047] The guiding assembly includes guide rails 6 parallel to both sides of the lead screw 13. The guide rails 6 have a T-shaped structure, and the lower end of the guide rails 6 is fixed to the support plate 2. A support slider 14 is slidably mounted on the guide rails 6, and the support slider 14 is fixedly connected to the bottom of the planting cylinder 8. In order to allow the planting cylinder 8 to move over a wider range, a moving block 28 is fixed to the inner end of the planting cylinder 8 (i.e., near the middle of the support plate 2).

[0048] The planting cylinder 8 adopts a cylindrical structure with an open top. A leak-proof mesh 9 is installed on the lower inner side of the planting cylinder 8. A support column 22 is fixed on the lower side of the leak-proof mesh 9, and the lower end of the support column 22 abuts against the inner bottom of the planting cylinder 8. A drain pipe 7 with a valve is also installed on the bottom side of the planting cylinder 8 to facilitate the discharge of excess water filtered out of the planting cylinder 8 for reuse.

[0049] In some optional embodiments, a water replenishment component is also included, which includes a water tank 16 fixed to the bottom of the lowest support plate 2. The water tank 16 has a water inlet 20 on its upper part and a water pump (not shown) installed at the bottom of the water tank 16. The outlet of the water pump is connected to a water supply pipe 19. A second annular cavity (not shown) is also opened on the inner outer side of the support plate 2. Two longitudinally adjacent second annular cavities are connected by a water supply pipe 15. The water supply pipe 19 is also connected to the second annular cavity of the lowest support plate 2. A first annular cavity 23 is opened on the upper inner side of the planting cylinder 8. The upper part of the planting cylinder 8 is also circumferentially distributed with nozzles 10 with downwardly inclined inner ends. The nozzles 10 are connected to the first annular cavity 23. The first annular cavity 23 is also connected to the second annular cavity of the support plate 2 in the same layer through a water supply pipe 3.

[0050] Preferably, a first valve and a second valve (not shown) are installed on the water inlet pipe 15 and the water supply pipe 3 respectively, which facilitates individual water replenishment control and saves water resources.

[0051] For the water replenishment component, the water inlet pipe 15 and the water supply pipe 3 can respectively accommodate the lifting and lowering of the support plate 2 and the movement of the planting cylinder 8; after the water tank 16 is filled with water, it can improve the stability of the device; by operating the water pump, water can be delivered to the second annular cavity through the water delivery pipe 19, and after being transmitted through the water inlet pipe 15 and the water supply pipe 3, it is delivered to each of the first annular cavities 23, and finally sprayed out through the nozzle 10 to achieve the purpose of water replenishment.

[0052] Example 2

[0053] The difference from Embodiment 1 is that the connection method of the guide assembly and the first bevel gear 24 and the lead screw 13 is improved, so that the planting cylinder 8 can be controlled in a stepped or other shape.

[0054] Specifically, the first bevel gear 24 is damped and rotatably connected to the lead screw 13; a limiting slider 26 is also slidably provided on the guide rail 6 on one side of the lead screw 13, and a fastening bolt 27 for locking and fixing it on the guide rail 6 is installed on the limiting slider 26. When the supporting slider 14 does not abut against the limiting slider 26, the first bevel gear 24 can drive the lead screw 13 to rotate stably. When the supporting slider 14 abuts against the limiting slider 26, the limiting slider 26 prevents the supporting slider 14 from moving, so the lead screw 13 cannot drive the moving block 28 to move. After the damping force is exceeded, the first bevel gear 24 rotates relative to the lead screw 13, which does not affect the motor 12 to continue to transmit power to the other planting cylinders 8. Thus, by adjusting the position of the limiting slider 26, one motor 12 can control the planting cylinders 8 of each layer to move to the designated position, thereby improving the effect of three-dimensional compact planting. When the planting cylinder 8 needs to be reset, the support slider 14 moves away from the limit slider 26, and the moving block 28 stops moving when it abuts against the inner end block 5. The first bevel gear 24 rotates again relative to the lead screw 13, waiting for the rest of the planting cylinders 8 to be reset. It is stable, reliable, convenient and quick.

[0055] Preferably, the first bevel gear 24 is connected to the lead screw 13 via a damped rotational connection. A suitable damping torque can be used based on actual testing, and no limitation is imposed. Specifically, this can be achieved using a disc spring to ensure that slippage does not affect the transmission of other layers.

[0056] The above embodiments of the present invention provide a compact three-dimensional planting rack for gardens, the working principle of which is summarized as follows:

[0057] The device uses an integrated transmission system driven by a motor 12 to enable the synchronous or stepwise expansion / contraction of the multi-layer planting tubes 8. At the same time, it works with the telescopic component 4 to adjust the spacing between layers, achieving the dual purpose of compact storage and optimized light.

[0058] Specific workflow:

[0059] First, activate the telescopic component 4 (such as an electric telescopic rod) to push the adjacent support plates 2 longitudinally apart, increasing the distance between each layer. This creates space for subsequent planting operations or allows the plants to receive sufficient sunlight, and this process does not affect the connection of the transmission components.

[0060] The motor 12 is started, and its power is transmitted to the end tube 21 through the output shaft. Power is transmitted synchronously from top to bottom through the sliding engagement of the cascaded prisms 17 and cascaded tubes 18, ensuring synchronized operation of all transmission components on the bearing plates 2. Each layer's end tube 21 or cascaded tube 18 drives the second bevel gear 25 to rotate. The second bevel gear 25 meshes with the first bevel gear 24, transmitting power to the lead screw 13, driving it to rotate. The rotating lead screw 13 causes the moving block 28 to move axially along the lead screw 13. Since the moving block 28 is fixedly connected to the bottom of the planting cylinder 8, it drives the entire planting cylinder 8 to expand or contract radially along the guide components (such as the guide rail 6 and the support slider 14).

[0061] When unfolded: Planting tube 8 extends outwards, expanding the growing space, preventing plants from shading each other, allowing them to receive better sunlight, and increasing overall stability. When retracted: Planting tube 8 retracts inwards, reducing the footprint and facilitating transportation or storage.

[0062] In embodiment 2, the first bevel gear 24 is connected to the lead screw 13 with damped rotation, and a limiting slider 26 is introduced. By adjusting the position of each layer's limiting slider 26 on the guide rail 6, the maximum extension distance of each layer of planting cylinder 8 can be set. When the support slider 14 of a certain layer moves to abut against the limiting slider 26, the axial movement of the lead screw 13 is stopped. At this time, if the motor 12 continues to run, the first bevel gear 24 will slip on the lead screw 13 (damped rotation), while other unrestricted layers can still continue to move. This allows a single motor 12 to enable each layer of planting cylinder 8 to unfold in a stepped manner according to a preset position, meeting more complex three-dimensional planting needs.

[0063] In addition, the water pump in the water tank 16 is activated, and water enters the second annular cavity of the lowest layer bearing plate 2 through the water supply pipe 19. The water is then transported upwards layer by layer through the water supply pipe 15 to the second annular cavity of each layer. It then flows into the first annular cavity 23 of the corresponding planting tube through the water supply pipe 3. Finally, the plants are sprayed with water through the circumferentially distributed nozzles 10. Valves can control independent water supply for each layer.

[0064] In summary, this compact, three-dimensional planting rack for gardens adjusts the layer height via an electric telescopic component 4, achieves radial extension and retraction of the planting cylinder 8 using a bevel gear-screw transmission system driven by a motor 12, and ensures smooth movement through a guide assembly. Furthermore, integrated transmission ensures synchronization, damping and limit designs enable step-by-step control, and a ring-shaped water system enables automated irrigation, thus achieving an intelligent transformation from compact storage to three-dimensional expansion, optimizing light and growing space.

[0065] There are no specific limitations on the control, model, and circuit connection of each component; they can be flexibly configured in practical applications. For example, a storage battery can be used for power supply, facilitating cyclic use.

[0066] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve any improvement to the software and methods.

[0067] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
