Description

Technical Field

[0001] The present invention relates to the technical field of municipal greening, and particularly to a cultivation device and a cultivation method for municipal greening maintenance. Background Art

[0002] Planting trees, planting grass and flowers in the city to cover or decorate a certain ground area is municipal greening. Municipal greening is an activity of planting plants to improve the urban environment. The same goes for landscape gardening, which involves planting trees, planting grass and flowers in some spaces within the garden to achieve the overall greening and aesthetic effects. The existing municipal greening maintenance has developed rapidly in various forms. In the process of municipal greening maintenance, these flowers, plants and trees are essential, and they need to be cultivated before construction.

[0003] In the prior art, in a cultivation device and a cultivation method for a building landscape garden and municipal greening maintenance disclosed in a Chinese patent document with the publication number CN116158282B, during use, after multiple cultivation racks are installed on Track 1 and Track 2, the cultivation personnel cultivate green plants through the cultivation pots on the cultivation racks. The distance between each cultivation rack can be adjusted to facilitate the extraction of the cultivation cylinders on the cultivation racks. When adding a culture solution into the cultivation cylinders, the culture solution can enter the first extraction cylinder ring through the liquid inlet pipe, and then be discharged through the drain hole 3 at the bottom of the first extraction cylinder ring and fall into the cultivation cylinders on the cultivation racks. This method can avoid the waste caused by the culture solution falling outside the cultivation cylinders. When it is necessary to spray and irrigate the cultivation cylinders, the first displacement housing can be arranged horizontally to increase the spraying area of the cultivation cylinders on the cultivation racks. However, similar to the traditional method, in the process of pulling out greening plants with the traditional device, the direct pulling out method is usually adopted, lacking a root cutting mechanism, which easily causes the roots to break or remain in the groove, affecting the subsequent survival rate and planting neatness of the plants. In addition, the traditional structure usually cannot effectively reduce the water flow rate. During the process of direct drainage of water and fertilizer, the speed is relatively fast, making it difficult for the roots to fully absorb nutrients, and at the same time weakening the recycling efficiency of resources.

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with specific embodiments.

[0023] As shown Figures 1 to 10 in the figure, the cultivation device for municipal greening maintenance includes a water and fertilizer tank 1 and a number of mounting seats 2 located around the water and fertilizer tank 1. A cultivation rack 3 is provided on each of the number of mounting seats 2. A pumping pipe 4 is provided in the middle of the top of the water and fertilizer tank 1. The top end of the pumping pipe 4 is connected to a water pump 5. A number of conveying pipes 6 are respectively provided around the water pump 5. The other ends of the number of conveying pipes 6 are respectively connected to the tops of the number of cultivation racks 3. A return pipe 7 is provided on one side of each of the number of mounting seats 2. The other ends of the return pipes 7 are respectively connected to one side of the water and fertilizer tank 1. A number of cultivation grooves 11 are opened above the cultivation rack 3; a number of cultivation components are provided inside the number of groups of cultivation grooves 11, and the cultivation components are used for cultivating greening plants; a number of diversion components are provided inside the number of cultivation racks 3, and the number of diversion components are respectively provided below the number of groups of cultivation components. The diversion component includes a guiding module and a decelerating module. The guiding module is used to guide the water and fertilizer to the lower part of the cultivation component, and the decelerating module is used to reduce the rate of the downward flow of the water flow. Each of the number of groups of cultivation grooves 11 is provided with two, and the number of groups of cultivation grooves 11 are arranged in an interlaced manner. The two cultivation grooves 11 in each group are arranged oppositely. An extension block 8 is also provided on one side of the mounting seat 2. A mounting plate 9 is fixedly installed on one side of the extension block 8. A lighting lamp 10 is provided inside the mounting plate 9; The water pump 5 pumps the nutrient solution in the water and fertilizer tank 1 to the tops of multiple cultivation racks 3, and accurately supplies it to the upper part of each cultivation groove 11 through the conveying pipe 6, forming a unified and centralized control liquid supply system. Then, by setting the return pipe 7, the excess water and fertilizer liquid is returned to the water and fertilizer tank 1, realizing the recycling of nutrients, reducing waste, and improving the economy and environmental protection of the irrigation system. Each group of cultivation grooves 11 is arranged in an opposite and interlaced manner, improving the space utilization rate, enabling more greening plants to be planted in a limited area, meeting the needs of high-density municipal greening, and at the same time being conducive to the uniform distribution of light and avoiding the problem of shading. The main function of the guiding module is to accurately guide the water and fertilizer liquid to the area below the cultivation groove 11 after the water and fertilizer liquid enters the inside of the cultivation rack 3 from the conveying pipe 6, ensuring that the water and fertilizer can be accurately supplied to the soil or substrate area where the plant roots are located, without deviation, uneven spraying or leakage, thereby improving the utilization efficiency of the water and fertilizer. The decelerating module plays a role after the guiding is completed, reducing the speed of the downward penetration of the water flow, prolonging the residence time of the water and fertilizer around the roots, allowing the plants to have sufficient time to absorb water and nutrients, preventing nutrient loss or root burden caused by too fast flow rate, and thus improving the overall irrigation efficiency and plant health.

[0024] As shown Figures 1 to 6As shown in the figure, the cultivation component includes a cultivation base 12 arranged inside the cultivation tank 11. One end of the cultivation base 12 is provided with a positioning base 21. The outer surface of the top of the positioning base 21 is provided with a plurality of mounting posts 25. A rotating sleeve 22 is rotatably sleeved on the positioning base 21. A plurality of inclined driving grooves 23 are formed on the outer circumference of the rotating sleeve 22. A plurality of cutting blades 26 are rotatably installed between the positioning base 21 and the rotating sleeve 22. The bottoms of the plurality of cutting blades 26 are all provided with sliding posts 27. The plurality of sliding posts 27 are respectively slidably installed inside the plurality of driving grooves 23. A mounting hole 28 is formed on one side of each of the plurality of cutting blades 26. The cutting blade 26 is rotatably installed on the mounting post 25 through the mounting hole 28. A driving rod 32 is further provided on one side of the rotating sleeve 22. When the driving rod 32 is controlled to drive the rotating sleeve 22 to rotate, the plurality of cutting blades 26 approach or move away from each other to trim the roots of the green plants. A plurality of positioning grooves 24 are formed on the top of the rotating sleeve 22 along the outer circumference. A cover plate 29 is further provided on the top surface of the rotating sleeve 22. A plurality of positioning blocks 30 adapted to the positioning grooves 24 are provided at the bottom of the cover plate 29. A cultivation extension cylinder 31 is provided on the top surface of the cover plate 29; When the green plants complete a cultivation cycle, the operator can push the driving rod 32 provided on one side of the rotating sleeve 22. The operation of the driving rod 32 causes the rotating sleeve 22 to start rotating on the positioning base 21. A plurality of inclined driving grooves 23 are provided on the outer circumference of the rotating sleeve 22. A sliding post 27 is slidably installed inside the driving groove 23. The bottom of the sliding post 27 is connected to a plurality of cutting blades 26. One side of the cutting blade 26 is rotatably installed on the mounting post 25 on the positioning base 21 through the mounting hole 28. As the rotating sleeve 22 rotates, the inclined structure of the driving groove 23 will push the sliding post 27 to slide, driving the cutting blades 26 to rotate and approach synchronously, and finally realizing a movement trend of approaching from the periphery to the center, so as to precisely trim the roots of the plants, form a neat root mass, prevent the root systems from being entangled and causing difficulties in pulling out or breaking, and after the root cutting is completed, the plants can be smoothly pulled out for loading or transplanting operations. The actions are smooth and the force is balanced throughout the process, ensuring the integrity of the root system and the safety and efficiency of the operation. The advantage of doing this is that by setting the rotatable rotating sleeve 22 to drive the plurality of cutting blades 26 to approach synchronously, the neat cutting of the roots of the plants can be realized, effectively preventing the root systems from breaking due to too tight biting when pulling the plants out of the cultivation tank 11, reducing the phenomenon of roots remaining in the tank, and the neatly cut roots are convenient for loading, handling and re-planting with unified specifications, improving the adaptability of the green plants to transplantation between different locations and different soils, and being suitable for large-scale maintenance of municipal greening or nursery stock production scenarios.

[0025] As Figure 7 、 Figure 8As shown, the guide module includes two collecting boxes 13 fixedly installed inside the culture rack 3, the two collecting boxes 13 respectively correspond to the bottoms of two culture tanks 11 in one group, a partition 14 is commonly provided in the middle between the two collecting boxes 13, a triangular cone-shaped guide block 15 is provided on the top of the partition 14, the bottoms of the two collecting boxes 13 are both inclined, the inclination directions of the two collecting boxes 13 are oppositely arranged, and a plurality of drain ports 16 are provided on one side of the collecting box 13 away from the partition 14; When the water pump 5 is started, water and fertilizer are transported to the culture tank 11 above through the delivery pipe 6 to irrigate and fertilize the plants. The excess water and fertilizer liquid flows into the two collecting boxes 13 arranged below through leakage or overflow at the bottom of the culture tank 11. The two collecting boxes 13 correspond to the two culture tanks 11 in each group respectively. During the falling process, the water flow first passes through the triangular cone-shaped guide block 15 in the middle. The guide block 15 disperses the direction of the water flow. After the water flow is guided to the collection boxes 13 on the left and right sides, nutrients are absorbed in the collection boxes 13. Under the guidance of the inclined bottom surface, the water flows in the direction away from the central partition 14 respectively. Since the two collection boxes 13 are inclined in opposite directions, the water flows finally converge to the drain ports 16 at both ends and flow downward.

[0026] like Figures 7 to 10 As shown, the deceleration module includes a deceleration block 17 arranged below the water outlet 16, a liquid inlet groove is arranged on the top of the deceleration block 17, a through groove 18 is opened inside the deceleration block 17, and a plurality of reflux grooves 19 are staggeredly opened on both sides of the through groove 18, and the plurality of reflux grooves 19 are arranged in an arc shape on the side away from the liquid inlet groove, and an inclined diverter block 20 is further arranged in the middle of the inner part of the reflux groove 19, and one side of the diverter block 20 is in an arc shape and the other side is in an inclined shape; When the excess water and fertilizer on the upper part of the culture tank 11 flows along the guide block 15 and the collection box 13 to the drain port 16, the water flows downward into the liquid inlet groove on the top of the speed reduction block 17 arranged just below the drain port 16. At this time, the water flow is first slowly accepted due to the existence of the liquid inlet groove to buffer its downward kinetic energy. Then the water flows into the through groove 18 inside the speed reduction block 17. A number of reflux grooves 19 are staggered on both sides of the through groove 18. These reflux grooves 19 are connected to the main through groove 18, so that the water flow needs to continuously bypass the left and right reflux paths during the flow process. An inclined diverter block 20 is provided. The arc side of the diverter block 20 guides the water flow to enter, and the inclined side changes its direction, so that the water flow forms multiple turning paths in the trough, thereby significantly slowing down the water flow speed, and finally making the water flow stably and evenly flow out of the bottom of the deceleration block 17 after multiple guidance and enter the next-level reflux system or collection and treatment device. The whole process is carried out through multiple flow rate controls and path extensions, which not only ensures the drainage efficiency, but also slows down the fluidity of water and fertilizer, giving the roots of the plants sufficient absorption time, while improving the recycling efficiency of water and fertilizer resources.

[0027] The present invention also discloses a cultivation method for municipal greening maintenance, which is applied to the cultivation device for municipal greening maintenance, and includes the following steps: S1: Start the water pump 5, and pump the water and fertilizer in the water and fertilizer tank 1 to the conveying pipe 6 through the pumping pipe 4; S2: The water and fertilizer are evenly conveyed to the top of each cultivation rack 3 through the conveying pipe 6 to irrigate the plants in the cultivation tank 11; S3: The water and fertilizer seep down or the excess part flows into the collection box 13 in the guiding module through the bottom of the cultivation tank 11; S4: The collection box 13 guides the water and fertilizer into the water outlet 16 under the guidance of the diversion block 15; S5: The water flow enters the deceleration module, and the flow rate is slowed down through the through groove 18 and the return groove 19 inside the deceleration block 17 to extend the residence time of the water and fertilizer; S6: The water and fertilizer finally flow back to the water and fertilizer tank 1 through the return pipe 7 to realize recycling; S7: When the plant cultivation period ends, push the driving rod 32 to rotate the rotating sleeve 22, drive the cutting edge 26 to approach, and neatly cut the roots to facilitate pulling out and transplanting; Compared with the prior art, by modularly integrating functions such as water supply, diversion, deceleration, and root cutting, precise irrigation and efficient recovery of water and fertilizer are achieved, greatly improving the water resource utilization efficiency. And the residence time of water and fertilizer around the roots is extended through the deceleration module to enhance the absorption effect of plants. In addition, the set rotatable cutting structure can synchronously cut the roots after the plant cycle cultivation ends, preventing root breakage or residue during the pulling out process, ensuring the integrity of the roots, facilitating subsequent loading and transportation and standardized transplantation, effectively improving the greening maintenance efficiency and survival rate, and is particularly suitable for the large-scale and high-density maintenance scenarios of municipal greening.
