Description

Technical Field

[0001] This invention relates to the field of greening cultivation technology, and in particular to a modular urban greening cultivation device. Background Technology

[0002] Urban greening is an important measure to improve the quality of the urban ecological environment, beautify the urban landscape, and improve the living environment of residents. Green vegetation in cities can lower the temperature and increase the air humidity. The canopy of trees can block sunlight and reduce the heat absorbed by the ground, thereby reducing the urban heat island effect.

[0003] A search revealed that Chinese patent CN222532315U discloses a municipal greening cultivation device, including a cultivation box with a filtration mechanism and spraying mechanisms on both the front and rear sides. The spraying mechanism includes a moving component and a water outlet component. The moving component includes an arc-shaped plate, a telescopic plate fixedly connected to the outer side of a ring-shaped slider, connecting plates fixedly connected to the upper ends of both the front and rear sides of the cultivation box, and a moving plate fixedly connected to the outer side of a T-shaped block. This municipal greening cultivation device, through the spraying mechanism, allows the water pump to circulate water from the cultivation box through a first water pipe to a second water pipe, which then sprays the surface of the green vegetation through nozzles. A rotating shaft drives the telescopic plate to rotate, and the telescopic plate rotates on the rotating rod surface, causing the moving plate to move as well. When the moving plate moves, it causes the T-shaped block to slide within a T-slot, allowing the nozzles to spray different locations on the green vegetation. However, this solution still has the following shortcomings in practical use:

[0004] In the process of urban road greening construction, when planting boxes are installed in the middle of roads to add greenery and beautify the environment, the initial stage of plant cultivation presents challenges. At this stage, the roots of newly planted plants are not yet fully developed and firmly anchored in the soil, resulting in poor overall plant stability. Furthermore, the complex traffic environment in the middle of roads means that if the planting box is located on a section with heavy truck traffic, the large trucks will generate significant vibrations, which will be transmitted through the ground to the planting box, affecting the root stability of the plants inside. Simultaneously, the strong airflow generated by the high-speed trucks will impact the plants in the box, causing the already fragile plants to sway. These airflows will interfere with the plants' normal growth posture, disrupt the delicate balance between the plants and the soil that has just been established, and ultimately severely affect the normal and stable growth of the plants in the planting box, reducing the effectiveness of road greening and the survival rate of the plants. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that in the existing technology, when planting boxes are installed in the middle of urban roads for greening, the roots of the green plants are not firm and the plants are unstable in the initial stage of cultivation. If the road section where the planting box is located has a large truck traffic, the vibration of the trucks and the strong airflow generated by high-speed driving, or the high-speed airflow of the vehicles, will impact the plants, disrupt their balance with the soil, and seriously affect the normal and stable growth of the green plants. To this end, we propose a modular urban greening cultivation device.

[0006] To achieve the above objectives, this application adopts the following technical solution: a modular urban greening cultivation device, comprising a cultivation box and two mounting seats symmetrically arranged on the top surface of the cultivation box.

A drive component corresponding to the soil loosening component is provided on the support. Two sets of anti-caking structures are symmetrically provided on the bottom surface of the soil loosening frame.

[0008] The wind-blocking component includes a shaft fixedly installed on the inner wall of the guardrail frame, and a baffle is provided on the outer wall of the shaft.

[0009] Preferably, the soil loosening assembly further includes a crank rotatably mounted on the side of the fixed frame, and the top end of the transmission rod is rotatably fitted onto the outer wall of the crank.

[0010] Preferably, the drive assembly includes a drive motor fixedly mounted on the top surface of the bracket, a drive gear fixedly mounted on the output end of the drive motor, a plurality of fixed teeth arranged in a ring array fixedly mounted on the inner wall of the gear ring, and the drive gear meshing with the fixed teeth, and a plurality of the fixed frames at the ends away from the positioning ring are rotatably mounted with linkage gears meshing with the gear ring through mounting plates, and the crank at the end away from the fixed frame is fixedly connected to the linkage gears.

[0011] Preferably, a rotating sleeve is rotatably fitted on the outer wall of the shaft, the baffle is fixedly installed on the outer wall of the rotating sleeve, a torsion spring is provided at the top end of the rotating sleeve, and the two ends of the torsion spring are fixedly connected to the rotating sleeve and the shaft, respectively.

[0012] Preferably, the support assembly includes an adjustable telescopic rod hinged to the top surface of the support plate, an adjusting plate hinged to the top surface of the positioning ring, a support plate rotatably mounted on the top of the adjusting plate, and the telescopic end of the adjustable telescopic rod hinged to the side of the adjusting plate.

[0013] Preferably, the support plate is arc-shaped, and the surface of the support plate has a number of ventilation holes.

[0014] Preferably, the anti-caking structure includes a soil loosening cylinder fixedly installed on the bottom surface of the soil loosening frame, a connecting cylinder extending through the bottom end of the soil loosening cylinder, a fixing plate fixedly installed at the bottom end of the connecting cylinder, a bottom insert cylinder slidably fitted onto the outer wall of the connecting cylinder, a spring fixedly installed between the inner top surface of the bottom insert cylinder and the top surface of the fixing plate, a sponge provided on the inner wall of the bottom insert cylinder, and a plurality of evenly distributed seepage holes opened on the outer wall of the bottom insert cylinder.

[0015] Preferably, the outer diameter of the loosening cylinder and the bottom insertion cylinder are the same, and the initial length of the loosening cylinder and the bottom insertion cylinder is the same as the length of the loosening rod.

[0016] Preferably, a frame plate is fixedly installed on the top side of each of the two mounting bases, a water storage tank is fixedly installed on the top of the frame plate, a water collection hopper is provided through the top surface of the water storage tank, a conduit is provided on the bottom surface of the water storage tank, and the end of the conduit away from the water storage tank is connected to the sponge.

[0018] The technical effects and advantages of this invention are as follows:

[0019] In this invention, the baffle can swing with the airflow under the action of the torsion spring, changing the direction of the airflow, reducing the direct impact on the green plants, ensuring stable growth, and blocking the headlights of oncoming vehicles when driving at night, improving driving safety. At the same time, when watering by a sprinkler truck, the baffle can block a large flow of water, preventing the roots of the green plants from being washed away, thus playing a protective role.

[0020] In this invention, the positioning ring and the adjusting telescopic rod can support the root system of the green plants, reducing the impact of vibration from the truck driving. The drive motor drives the drive gear to rotate, and the linkage structure causes the soil loosening rod on the bottom of the soil loosening frame to reciprocate and insert into the soil, realizing convenient soil loosening. The power supply can be a battery or solar energy, which is mature and reliable.

[0021] In this invention, the water collection hopper can collect water into the storage tank for storage. The water is guided to the sponge through the conduit. After accumulating to a certain level, it is discharged into the soil through the seepage port. When loosening the soil, the bottom insert is inserted into the soil to squeeze the sponge, so that water is discharged and the soil is moistened, which enhances the anti-compacting effect. When the bottom insert is removed from the soil, it can be reset under the action of the spring for normal use, which increases the practicality of the device. Attached Figure Description

[0034] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the present invention provides a technical solution: a modular urban greening cultivation device, including a cultivation box 11 and two mounting seats 12 symmetrically arranged on the top surface of the cultivation box 11. A guardrail frame 13 is fixedly installed on the top surface of the mounting seat 12. Two supports 21 are symmetrically fixedly installed on the side of the top surface of the mounting seat 12. A positioning ring 22 is fixedly installed at the end of the support 21. A plurality of support plates 23 arranged in a ring array are fixedly installed on the outer wall of the positioning ring 22. A fixing ring shell 24 is fixedly installed at the end of the plurality of support plates 23 away from the positioning ring 22. A toothed ring 25 is rotatably installed on the inner wall of the fixing ring shell 24. A plurality of fixing frames 41 arranged in a ring array are fixedly installed on the bottom surface of the positioning ring 22. A plurality of wind-blocking components arranged in a linear array are provided on the inner wall of the guardrail frame 13.

[0036] The wind-blocking assembly includes a shaft 61 fixedly installed on the inner wall of the guardrail frame 13. A baffle 63 is provided on the outer wall of the shaft 61. A rotating sleeve 62 is rotatably fitted on the outer wall of the shaft 61. The baffle 63 is fixedly installed on the outer wall of the rotating sleeve 62. A torsion spring 64 is provided at the top of the rotating sleeve 62, and the two ends of the torsion spring 64 are fixedly connected to the rotating sleeve 62 and the shaft 61, respectively.

[0037] In use, urban greening plants can be cultivated in cultivation boxes 11, and several cultivation boxes 11 can be fixed in the middle of the road. Adjacent cultivation boxes 11 can be fixed together with components, and adjacent guardrail frames 13 can be in a close fit, forming a green separation strip between roads. The cultivation boxes 11 can be modularly installed, making them more convenient to use. In daily use, in the initial state, the baffle 63 on the outer wall of the rotating sleeve 62 is tilted under the action of the torsion spring 64, and the baffle 63 extends out of the guardrail frame 13. When a large truck passes through the cultivation box 11, the airflow generated can first impact the baffle 63. When the airflow impacts the baffle 63, the baffle 63 and the rotating sleeve 62 can rotate. Under the action of the torsion spring 64, the baffle 63 swings back and forth and can then return to its original position, thereby changing the direction of airflow and reducing the direct impact of airflow on the green plants in the cultivation box 11. The presence of baffles 63 on both sides of the cultivation box 11 ensures stable growth of the green plants. These baffles also block the headlights of oncoming vehicles at night, enhancing driving safety. Furthermore, given the potentially low rainfall in the city where the cultivation box 11 is located, requiring regular watering by maintenance personnel using sprinkler trucks, the water flow from the top or side can be significantly impacted by the baffles 63. This prevents the water from washing away the roots, thus protecting them. This dual protection ensures stable transplanting and development of the trees within the cultivation box 11, allowing them to thrive and grow healthily.

[0038] Reference Figure 6 As shown, the top surface of the positioning ring 22 is provided with several sets of support components arranged in a ring array. The support components include an adjusting telescopic rod 31 hinged to the top surface of the support plate 23. An adjusting plate 32 is hinged to the top surface of the positioning ring 22. A support plate 33 is rotatably installed on the top of the adjusting plate 32. The telescopic end of the adjusting telescopic rod 31 is hinged to the side of the adjusting plate 32. The support plate 33 is arc-shaped, and several ventilation holes are opened on the surface of the support plate 33.

[0039] During daily use, the positioning ring 22 is located on the outside of the plant in the cultivation box 11 and can support the plant according to its growth. The adjusting telescopic rod 31 can be adjusted, which can drive the adjusting plate 32 to rotate on the top surface of the positioning ring 22. After the adjusting plate 32 is adjusted, the support plate 33 can be adjusted so that the support plate 33 supports the root system of the plant, reducing the impact of vibration caused by the truck driving on the plant. At the same time, through the use of the support plate 33, the green trees in the cultivation box 11 can develop more uniformly and the cultivation effect is better.

[0040] Reference Figure 2-5 As shown, a soil loosening component is provided on the fixed frame 41. The soil loosening component includes a transmission rod 42 that passes through the top surface of the fixed frame 41. A soil loosening frame 44 is fixedly installed at the bottom end of the transmission rod 42. Several soil loosening rods 45 are fixedly installed on the bottom surface of the soil loosening frame 44. The soil loosening component also includes a crank 43 that is rotatably installed on the side of the fixed frame 41. The top end of the transmission rod 42 is rotatably fitted onto the outer wall of the crank 43. A drive component corresponding to the soil loosening component is provided on the bracket 21. Two sets of anti-caking structures are symmetrically provided on the bottom surface of the soil loosening frame 44.

[0041] The drive assembly includes a drive motor 51 fixedly mounted on the top surface of the bracket 21. A drive gear 52 is fixedly mounted on the output end of the drive motor 51. Several fixed teeth 53 arranged in a ring array are fixedly mounted on the inner wall of the gear ring 25. The drive gear 52 meshes with the fixed teeth 53. Several fixed brackets 41 are rotatably mounted with linkage gears 54 that mesh with the gear ring 25 through the mounting plate at one end. The crank 43 is fixedly connected to the linkage gear 54 at one end away from the fixed bracket 41.

[0042] To ensure better growth of the urban greenery in the cultivation box 11, the soil in the cultivation box 11 needs to be loosened regularly. During regular soil loosening, the drive motor 51 can be turned on to drive the drive gear 52 to rotate. The drive gear 52 meshes with the fixed teeth 53 on the gear ring 25, thereby driving the gear ring 25 to rotate on the inner wall of the fixed ring shell 24. When the gear ring 25 rotates, it drives the linkage gear 54 that meshes with it to rotate, thereby causing several cranks 43 to rotate synchronously. When the cranks 43 rotate, they drive the transmission rod 4 2. The vertical reciprocating sliding along the fixed frame 41 allows the soil loosening rod 45 on the bottom surface of the soil loosening frame 44 at the bottom of the transmission rod 42 to reciprocate and insert into the soil in the cultivation box 11, thereby achieving the effect of loosening the soil. The power supply method of the drive motor 51 can be a battery or solar power. The power supply method here is an existing mature technology and will not be described in detail here. By loosening the soil of the green forest tree breeding soil, it is ensured that the roots of the trees can get enough oxygen, so as to achieve rapid transplanting and breeding and grow more firmly.

[0043] Reference Figure 1 and Figure 10As shown, the anti-caking structure includes a soil loosening cylinder 71 fixedly installed on the bottom surface of the soil loosening frame 44. A connecting cylinder 72 is provided through the bottom end of the soil loosening cylinder 71. A fixing plate 73 is fixedly installed on the bottom end of the connecting cylinder 72. A bottom insert cylinder 74 is slidably fitted on the outer wall of the connecting cylinder 72. The outer diameters of the soil loosening cylinder 71 and the bottom insert cylinder 74 are the same. The initial lengths of the soil loosening cylinder 71 and the bottom insert cylinder 74 are the same as the length of the soil loosening rod 45. A spring 75 is fixedly installed between the inner top surface of the bottom insert cylinder 74 and the top surface of the fixing plate 73. A sponge 76 is provided on the inner wall of the bottom insert cylinder 74. Several evenly distributed seepage ports 77 are opened on the outer wall of the bottom insert cylinder 74.

[0044] A frame plate 81 is fixedly installed on the top side of each of the two mounting bases 12. A water storage tank 82 is fixedly installed on the top of the frame plate 81. The horizontal position of the water storage tank 82 is at least higher than the horizontal position of the sponge 76. A water collection hopper 83 is provided through the top surface of the water storage tank 82. A conduit 84 is provided on the bottom surface of the water storage tank 82, and the end of the conduit 84 away from the water storage tank 82 is connected to the sponge 76.

[0045] During daily use, when watering the plants in the cultivation box 11 or during rain, water can enter the water storage tank 82 through the water collection hopper 83 to store water resources. Since the height of the water storage tank 82 is at least higher than the height of the sponge 76, the water in the water storage tank 82 can be guided to the sponge 76 through the conduit 84. When the water in the sponge 76 accumulates to a certain level, it can be discharged through the seepage outlet 77 and collected at the bottom of the bottom insert 74, dripping onto the soil in the cultivation box 11, further preventing water from overflowing. To prevent soil compaction, during soil loosening, the loosening frame 44 can drive the loosening cylinder 71 and the bottom insertion cylinder 74 to be inserted into the soil. When the bottom insertion cylinder 74 is inserted into the soil, it will slide upward along the connecting cylinder 72 under the action of resistance. At this time, the fixing plate 73 will squeeze the sponge 76, and the water in the sponge 76 can be discharged through the seepage port 77, which will have the effect of wetting the soil and enhancing the effect of preventing soil compaction. When it moves out of the soil, the bottom insertion cylinder 74 can be reset and used normally under the action of the spring 75.

[0046] Working Principle: In use, urban greening plants can be cultivated in cultivation boxes 11, and several cultivation boxes 11 can be fixed sequentially in the middle of the road. Adjacent cultivation boxes 11 can be fixed together using components, and adjacent guardrail frames 13 can be in a close fit, together forming a green dividing strip between roads. The cultivation boxes 11 can be modularly installed, making them more convenient to use. During daily use, in the initial state, the baffle 63 on the outer wall of the rotating sleeve 62 is tilted under the action of the torsion spring 64, and the baffle 63 extends out of the guardrail frame 13. When a large truck passes through the cultivation box 11, the resulting airflow can first impact the baffle 63. When the airflow impacts the baffle 63, both the baffle 63 and the rotating sleeve 62 can rotate. Under the action of the torsion spring 64, the baffle 63 swings back and forth and then returns to its original position, thereby changing the direction of airflow and reducing the direct impact of airflow on the cultivation box 11. The cultivation boxes 11 are equipped with baffles 63 on both sides to ensure stable growth of the green plants. These baffles also block the headlights of oncoming vehicles at night, ensuring safety. Furthermore, since the city where the cultivation boxes 11 are located may experience low rainfall, urban greening requires regular watering by maintenance personnel using sprinkler trucks. When watering by sprinkler trucks, the water flow is strong, so maintenance personnel can water from above or at an angle to the sides. The baffles 63 block the water flow from impacting the plant roots, preventing the roots from being washed away. This dual protection by the baffles 63 ensures stable transplanting and development of the trees within the cultivation boxes 11, allowing them to thrive.

[0047] During daily use, the positioning ring 22 is located on the outside of the plant in the cultivation box 11 and can support the plant according to its growth. The adjusting telescopic rod 31 can be adjusted, causing the adjusting plate 32 to rotate on the top surface of the positioning ring 22. After the adjusting plate 32 is adjusted, the support plate 33 can be adjusted to support the plant's root system, reducing the impact of vibrations from the truck's movement on the plant. Simultaneously, the use of the support plate 33 allows the trees in the cultivation box 11 to develop more uniformly, resulting in better cultivation. To ensure better growth of the urban greenery in the cultivation box 11, the soil needs to be loosened regularly. During regular loosening, the drive motor 51 can be activated to drive the drive gear 52 to rotate. Gear 52 meshes with the fixed teeth 53 on the gear ring 25, thereby driving the gear ring 25 to rotate on the inner wall of the fixed ring shell 24. When the gear ring 25 rotates, it drives the meshing linkage gear 54 to rotate, thereby causing several cranks 43 to rotate synchronously. When the cranks 43 rotate, they drive the transmission rod 42 to slide back and forth vertically along the fixed frame 41, so that the soil loosening rod 45 on the bottom surface of the soil loosening frame 44 at the bottom of the transmission rod 42 can reciprocate to insert into the soil in the cultivation box 11, thereby achieving the effect of loosening the soil. The power supply method of the drive motor 51 can be a battery or solar power. The power supply method here is an existing mature technology and will not be described in detail here. By loosening the soil of the green forest tree breeding soil, it is ensured that the roots of the trees can get enough oxygen, so as to achieve rapid transplanting and breeding and grow more firmly.

[0048] In daily use, during watering of the plants in the cultivation box 11 or during rain, water can enter the water storage tank 82 through the water collection hopper 83 to store water resources. Since the height of the water storage tank 82 is at least higher than the height of the sponge 76, the water in the water storage tank 82 can be guided to the sponge 76 through the conduit 84. When the water in the sponge 76 accumulates to a certain level, it can be discharged through the seepage outlet 77 and collected at the bottom of the bottom insert 74, dripping onto the soil in the cultivation box 11, further preventing water from accumulating. To prevent soil compaction, during soil loosening, the loosening frame 44 can drive the loosening cylinder 71 and the bottom insertion cylinder 74 to be inserted into the soil. When the bottom insertion cylinder 74 is inserted into the soil, it will slide upward along the connecting cylinder 72 under the action of resistance. At this time, the fixing plate 73 will squeeze the sponge 76, and the water in the sponge 76 can be discharged through the seepage port 77, which can moisten the soil and enhance the soil anti-compacting effect. When it moves out of the soil, the bottom insertion cylinder 74 can be reset and used normally under the action of the spring 75.

[0049] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
