Description

Technical Field

[0001] This invention relates to the field of municipal greening technology, and in particular to a cultivation device and cultivation method for municipal greening management. Background Technology

[0002] Planting trees, grass, and flowers in cities to cover or decorate certain areas is what we call municipal greening. Municipal greening is the activity of planting plants to improve the urban environment. Landscape gardening is the same; it involves planting trees, grass, and flowers in certain spaces within a garden to achieve overall greening and aesthetic effects. The management and maintenance of municipal greening is developing rapidly and takes many forms. In the process of managing and maintaining municipal greening, these flowers, grasses, and trees are indispensable, and they need to be cultivated before construction.

[0003] In the prior art, Chinese patent document CN116158282B, entitled "A Cultivation Device and Method for the Management of Architectural Landscape Gardening and Municipal Greening," describes a process where multiple cultivation racks are installed on tracks one and two. Cultivators use cultivation pots on the racks to cultivate plants. The distance between the racks is adjustable, facilitating the extraction of cultivation tubes. When nutrient solution is added to the tubes, it enters through an inlet pipe into a tube-retrieving ring, then drains through a drain hole at the bottom of the ring and falls back into the cultivation tubes on the racks. This method avoids waste caused by nutrient solution falling outside the tubes. When spraying water into the cultivation tube, the displacement shell can be arranged horizontally, thereby increasing the spraying area of ​​the cultivation tube on the cultivation rack. However, consistent with the traditional method, the traditional device usually adopts the method of direct pulling out during the process of removing green plants, lacking a root trimming mechanism, which makes the roots prone to breakage or remaining in the trench, affecting the subsequent survival rate and planting uniformity of the plants. In addition, the traditional structure usually cannot effectively reduce the water flow speed. During the process of direct water and fertilizer discharge, the speed is relatively fast, making it difficult for the roots to fully absorb nutrients, and also weakening the efficiency of resource recycling. Therefore, this application discloses a cultivation device and cultivation method for municipal greening management. Summary of the Invention

[0008] Preferably, a drive rod is also provided on one side of the rotating sleeve. When the drive rod is controlled to drive the rotating sleeve to rotate, the plurality of cutting blades move closer or further apart to trim the roots of the green plants.

[0009] Preferably, the top of the rotating sleeve is provided with several positioning grooves along its outer periphery, the top surface of the rotating sleeve is also provided with a cover plate, the bottom of the cover plate is provided with several positioning blocks that are adapted to the positioning grooves, and the top surface of the cover plate is provided with a culture extension tube.

[0010] Preferably, the guiding module includes two collection boxes fixedly installed inside the culture rack. The two collection boxes correspond to the bottom of two culture tanks in a set. A partition is provided in the middle between the two collection boxes, and a triangular cone-shaped guide block is provided on the top of the partition.

[0011] Preferably, the bottoms of both collection boxes are inclined, the inclination directions of the two collection boxes are opposite, and each collection box has several drain outlets on the side away from the partition.

[0012] Preferably, the deceleration module includes a deceleration block disposed below the drain outlet. Each deceleration block has a liquid inlet groove on its top. The interior of the deceleration block has a through groove. Several return grooves are staggered on both sides of the through groove. The side of the return groove away from the liquid inlet groove is arranged in an arc shape. An inclined diverting block is also disposed in the middle of the interior of the return groove.

[0013] Preferably, an extension block is provided on one side of the mounting base, a mounting plate is fixedly installed on one side of the extension block, and a lighting lamp is provided on the inner side of the mounting plate.

[0014] This invention also discloses a cultivation method for municipal greening maintenance, applied to the aforementioned cultivation device for municipal greening maintenance, comprising the following steps: S1: Start the water pump to pump the water and fertilizer in the water and fertilizer tank to the delivery pipe through the pumping pipe; S2: Water and fertilizer are evenly delivered to the top of each cultivation rack through the delivery pipe to irrigate the plants in the cultivation trough; S3: Water and fertilizer seep down or excess flows into the collection box in the guide module through the bottom of the culture tank; S4: The collection box guides the water and fertilizer into the drain under the guidance of the guide block; S5: Water flows into the deceleration module, where the flow rate is slowed down by the through groove and return groove inside the deceleration block, thus extending the water-fertilizer residence time; S6: The water and fertilizer are finally returned to the water and fertilizer tank through the return pipe to achieve recycling; S7: When the plant cultivation cycle ends, push the drive rod to rotate the rotating sleeve, causing the cutting blade to come closer and neatly trim the roots, making it easier to pull out and transplant.

[0015] The beneficial effects of this invention are: 1. This cultivation device and method for municipal greening maintenance utilizes a cultivation component. A rotatable sleeve is mounted on a positioning seat, with several cutting blades and inclined drive grooves arranged between the sleeve and the seat. This allows the cutting blades to move inward synchronously, neatly cutting the roots of greening plants. This effectively avoids root breakage or residue problems caused by root entanglement or excessive clamping in traditional removal methods, improving root integrity and ensuring subsequent transplant survival rates and ease of operation. The cutting process features balanced force and stable movement, adapting to root structures of different diameters. The cut roots exhibit good uniformity, facilitating bulk loading, transportation, and standardized planting of seedlings. It is particularly suitable for large-scale plant management scenarios in municipal greening maintenance and nursery enterprises, improving the uniformity and standardization of root treatment and providing a stable foundation for subsequent transplanting operations.

[0016] 2. This cultivation device and method for municipal greening maintenance, through the setting of a guiding module, and the setting of paired inclined collection boxes and triangular cone-shaped guide blocks on the top of the central partition, achieves reasonable diversion and directional guidance of leaked water and fertilizer. It can effectively concentrate overflow or excess water and fertilizer into the designated drain area, avoiding water flow turbulence in the cultivation rack that causes waste or washes away plant roots. At the same time, it ensures balanced water flow output on both sides, improves drainage efficiency, optimizes the irrigation system circulation structure, provides a stable water and fertilizer environment for plant growth, extends the system service life and reduces maintenance costs.

[0017] 3. This cultivation device and method for municipal greening maintenance effectively controls the flow rate of water and fertilizer by incorporating a deceleration module, an inlet tank, staggered return tanks, and internal inclined diversion blocks. This allows the water flow to gradually slow down after passing through multiple turning paths, extending the residence time of water and fertilizer, improving the root's nutrient absorption efficiency, and preventing excessively fast water flow from impacting the cultivation structure or plants. This enhances the utilization rate of water and fertilizer resources and the overall performance of the ecological irrigation system, making it suitable for refined municipal greening maintenance scenarios requiring precise control of water flow and high recycling rates.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] like Figures 1 to 10 As shown, the cultivation device for municipal greening maintenance includes a water and fertilizer tank 1 and several mounting bases 2 around the water and fertilizer tank 1. Each mounting base 2 is equipped with a cultivation rack 3. A pumping pipe 4 is located at the top center of the water and fertilizer tank 1, with a water pump 5 connected to its top. Several conveying pipes 6 are arranged around the water pump 5, with the other ends of each conveying pipe 6 connected to the top of the cultivation racks 3. Each mounting base 2 has a return pipe 7 on one side, with the other end of each return pipe 7 connected to one side of the water and fertilizer tank 1. Several sets of cultivation troughs 11 are opened above the cultivation racks 3; several cultivation components are arranged inside the cultivation troughs 11. The cultivation component is used to cultivate green plants; several flow guiding components are set inside several cultivation racks 3, and several flow guiding components are respectively set below several groups of cultivation components. The flow guiding components include a guide module and a deceleration module. The guide module is used to guide water and fertilizer to the bottom of the cultivation component, and the deceleration module is used to reduce the downward flow rate of water. Several groups of cultivation tanks 11 are each set in pairs, and several groups of cultivation tanks 11 are arranged in an alternating manner. The two cultivation tanks 11 in each group are arranged opposite each other. An extension block 8 is also set on one side of the mounting base 2. An installation plate 9 is fixedly installed on one side of the extension block 8. A lighting lamp 10 is set on the inner side of the installation plate 9. Nutrient solution from the water-fertilizer tank 1 is pumped by water pump 5 to the top of multiple cultivation racks 3, and then precisely supplied to the top of each cultivation tank 11 via delivery pipe 6, forming a unified and centralized liquid supply system. Excess liquid is then returned to the water-fertilizer tank 1 via return pipe 7, achieving nutrient recycling, reducing waste, and improving the economy and environmental friendliness of the irrigation system. Each group of cultivation tanks 11 is arranged in a staggered, opposing pattern, improving space utilization and allowing for the planting of more greenery within a limited area, suitable for high-density urban greening needs. It also promotes even light distribution and avoids shading problems. The main guiding module... The function is to precisely guide the water and fertilizer solution into the area below the cultivation tank 11 after it enters the cultivation rack 3 from the delivery pipe 6, ensuring that the water and fertilizer can be accurately delivered to the soil or substrate area where the plant roots are located, without deviation, uneven spraying or leakage, thereby improving the utilization efficiency of water and fertilizer. The deceleration module plays a role after the guidance is completed, reducing the speed of water flow downward and prolonging the residence time of water and fertilizer around the roots, allowing the plants sufficient time to absorb water and nutrients, preventing nutrient loss or root burden caused by excessive flow rate, thereby improving the overall irrigation efficiency and plant health.

[0024] like Figures 1 to 6As shown, the culture assembly includes a culture seat 12 disposed inside a culture tank 11. A positioning seat 21 is provided at one end of the culture seat 12. Several mounting posts 25 are provided on the top outer surface of the positioning seat 21. A rotating sleeve 22 is rotatably fitted onto the positioning seat 21. Several inclined drive grooves 23 are formed on the outer periphery of the rotating sleeve 22. Several cutting blades 26 are rotatably mounted between the positioning seat 21 and the rotating sleeve 22. A sliding post 27 is provided at the bottom of each of the cutting blades 26. The sliding posts 27 are slidably installed inside the drive grooves 23. One side of each cutting blade 26... The rotating sleeve 22 has a mounting hole 28, through which the cutting blade 26 is rotatably mounted on the mounting post 25. A drive rod 32 is also provided on one side of the rotating sleeve 22. When the drive rod 32 is controlled to drive the rotating sleeve 22 to rotate, the cutting blades 26 move closer or further away from each other to cut the roots of the green plants. The top of the rotating sleeve 22 has several positioning grooves 24 along its outer periphery. The top surface of the rotating sleeve 22 is also provided with a cover plate 29. The bottom of the cover plate 29 is provided with several positioning blocks 30 that are compatible with the positioning grooves 24. The top surface of the cover plate 29 is provided with a cultivation extension tube 31. After the green plants have completed a certain cultivation cycle, the operator can push the drive rod 32 located on one side of the rotating sleeve 22. The operation of the drive rod 32 causes the rotating sleeve 22 to start rotating on the positioning seat 21. The outer circumference of the rotating sleeve 22 is provided with several inclined drive grooves 23. Sliding columns 27 are slidably installed inside the drive grooves 23. Several cutting blades 26 are connected to the bottom of the sliding columns 27. One side of the cutting blades 26 is rotatably installed on the mounting column 25 on the positioning seat 21 through the mounting hole 28. As the rotating sleeve 22 rotates, the inclined structure of the drive grooves 23 pushes the sliding columns 27 to slide, causing the cutting blades 26 to rotate synchronously and move closer, ultimately achieving a movement trend from the surroundings towards the center, thereby accurately trimming the plant roots and forming a neat root ball. To prevent root entanglement that could lead to difficulty in extraction or breakage, the plant can be easily pulled out for loading or transplanting after the roots are trimmed. The entire process is smooth and the force is even, ensuring the integrity of the root system and the safety and efficiency of the operation. The advantage of this is that by setting a rotatable rotating sleeve 22 to drive multiple cutting blades 26 to approach simultaneously, a neat cut can be made to the plant roots. This effectively prevents the roots from breaking due to excessive clamping when the plant is pulled out of the cultivation trough 11, reducing the phenomenon of roots remaining in the trough. Furthermore, the neatly trimmed roots are easy to load, transport, and replant in a standardized manner, improving the adaptability of greening plants to transplanting in different locations and soils. This is suitable for large-scale maintenance of municipal greening or seedling production scenarios.

[0025] like Figure 7 , Figure 8As shown, the guide module includes two collection boxes 13 fixedly installed inside the culture rack 3. The two collection boxes 13 correspond to the bottom of the two culture tanks 11 in a set. A partition 14 is provided in the middle between the two collection boxes 13. A triangular cone-shaped guide block 15 is provided on the top of the partition 14. The bottom of the two collection boxes 13 is inclined. The inclination directions of the two collection boxes 13 are opposite. Several drain outlets 16 are opened on the side of the collection box 13 away from the partition 14. When the water pump 5 starts, water and fertilizer are transported through the delivery pipe 6 to the upper cultivation tank 11 to irrigate and fertilize the plants. Excess water and fertilizer solution seeps or overflows from the bottom of the cultivation tank 11 into the two collection boxes 13 set below. The two collection boxes 13 correspond to the two cultivation tanks 11 in each group. During the water flow, it first passes through the triangular cone-shaped guide block 15 in the middle. The guide block 15 disperses the water flow direction, and the water flow is guided to the collection boxes 13 on the left and right sides. Nutrient absorption takes place in the collection boxes 13. Guided by the inclined bottom surface, the water flows away from the central partition 14. Since the two collection boxes 13 are inclined in opposite directions, the water flow eventually converges at the drain outlets 16 at both ends and flows downward.

[0026] like Figures 7 to 10 As shown, the deceleration module includes a deceleration block 17 located below the drain outlet 16. Each deceleration block 17 has an inlet groove on its top. The deceleration block 17 has a through groove 18 inside. Several return grooves 19 are staggered on both sides of the through groove 18. The side of the return grooves 19 away from the inlet groove is arc-shaped. An inclined diverter block 20 is also provided in the middle of the return groove 19. One side of the diverter block 20 is arc-shaped, and the other side is inclined. When excess water and fertilizer in the upper part of the culture tank 11 flows along the guide block 15 and the collection box 13 to the drain 16, the water flows downward and converges into the liquid inlet trough at the top of the deceleration block 17 located directly below the drain 16. At this time, the water flow is first slowly received by the liquid inlet trough, buffering its downward kinetic energy. Then the water flow enters the through channel 18 inside the deceleration block 17. Several return channels 19 are distributed alternately on both sides of the through channel 18. These return channels 19 are connected to the main through channel 18, so that the water flow must continuously bypass the left and right return paths during the flow process. In each return channel 19 An inclined diversion block 20 is provided. The curved side of the diversion block 20 guides the water flow in, and the inclined side changes its direction, so that the water flow forms multiple turning paths in the tank, thereby significantly slowing down the water flow speed. Finally, after multiple guidances, the water flows out of the bottom of the deceleration block 17 stably and evenly and enters the next stage of the return system or collection and treatment device. The whole process, through multiple flow rate controls and path extensions, not only ensures drainage efficiency, but also slows down the flow of water and fertilizer, giving the plant roots sufficient time to absorb, and at the same time improves the recycling efficiency of water and fertilizer resources.

[0027] This invention also discloses a cultivation method for municipal greening maintenance, and a cultivation device for municipal greening maintenance applied to the present invention, comprising the following steps: S1: Start water pump 5 and pump water and fertilizer in water and fertilizer tank 1 to delivery pipe 6 through pumping pipe 4. S2: Water and fertilizer are evenly transported to the top of each cultivation rack 3 through the conveying pipe 6 to irrigate the plants in the cultivation trough 11; S3: Water and fertilizer seep down or excess flows into the collection box 13 in the guide module through the bottom of the culture tank 11; S4: The collection box 13 guides the water and fertilizer into the drain outlet 16 under the guidance of the guide block 15; S5: Water flows into the deceleration module and slows down the flow rate through the through groove 18 and return groove 19 inside the deceleration block 17, thus extending the water-fertilizer residence time. S6: The water and fertilizer are finally returned to the water and fertilizer tank 1 through the return pipe 7 to achieve recycling; S7: When the plant cultivation cycle ends, push the drive rod 32 to rotate the rotating sleeve 22, which will cause the cutting blade 26 to come closer and neatly trim the roots, making it easier to pull out and transplant. Compared to existing technologies, this system integrates modular functions such as water supply, diversion, deceleration, and root trimming, achieving precise irrigation and efficient recycling of water and fertilizer, significantly improving water resource utilization efficiency. The deceleration module extends the residence time of water and fertilizer around the roots, enhancing plant absorption. Furthermore, the rotatable trimming structure allows for simultaneous cutting of the roots after the plant's cultivation cycle, preventing root breakage or residue during extraction, ensuring root integrity, facilitating subsequent loading, transportation, and standardized transplanting, effectively improving greening maintenance efficiency and survival rate. It is particularly suitable for large-scale, high-density maintenance scenarios in municipal greening.
