Description

Technical Field

[0001] This utility model relates to the technical field of green belt maintenance, specifically to a foldable irrigation device for maintaining urban road green belts. Background Technology

[0002] Urban roadside green belts refer to the vegetation areas along urban roadsides, including trees, lawns, and low shrubs, and are an important component of the urban greening system. These green belts not only beautify the urban environment but also improve air quality, reduce noise pollution, and provide recreational spaces for citizens. The maintenance of these green belts is crucial for preserving their ecological functions and aesthetic appeal. Maintenance work includes irrigation, fertilization, pruning, and pest and disease control. Irrigation is a key element in ensuring healthy plant growth. Proper irrigation using irrigation systems can meet the plants' water needs, promote photosynthesis and growth, and thus maintain the vitality of the green belts.

[0003] For example, Chinese Patent Publication No. CN222128944U discloses a maintenance and irrigation device for urban road green belts, relating to the field of green belt irrigation technology. The device includes: a protective box; a water supply pipe for supplying water; a movable base plate located below the protective box for moving the entire irrigation device; a movable connecting unit connected to the protective box for driving the needle-type irrigation nozzle to rotate and extend laterally and vertically; the needle-type irrigation nozzle is connected to the movable connecting unit for evenly spraying water onto the bottom of the green belt to irrigate it. This patent document, through the design of the needle-type irrigation nozzle, can evenly spray water onto the bottom of the green belt, avoiding the plant leaves and ensuring that the water fully covers the roots of the plants. This promotes the growth and healthy development of the plants, reduces water waste, and, through its movable design, facilitates mobile irrigation between urban roads.

[0004] However, the aforementioned patent documents still have the following defects in practice: Although the equipment can irrigate green belts, it cannot flexibly adjust the height of the irrigation nozzles according to the height of different plants during use, and cannot ensure that each plant receives sufficient water, resulting in uneven irrigation or water waste. Furthermore, it cannot rotate during spraying, which prevents the water from being distributed more evenly within the green belt and from being sprayed onto the plants at different angles and directions, potentially leading to localized water accumulation or insufficient irrigation, thereby reducing irrigation efficiency. Summary of the Invention

[0005] The purpose of this utility model is to provide a foldable irrigation device for the maintenance of urban road green belts, so as to overcome the above-mentioned defects in the prior art.

A gear is rotatably connected to the square box through a rotating rod. The gear meshes with the rack through a hole opened in the square box. A worm is also rotatably connected to the square box, and the worm meshes with a worm wheel on the rotating rod.

[0010] Preferably, the spraying mechanism includes a support pipe located at the upper end of the sliding pipe. The support pipe has a filter screen in the middle of the sunshade cloth.

[0021] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of this utility model, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the concept and technical solution of this utility model.

[0022] like Figure 1-6 As shown, this utility model provides a foldable irrigation device for the maintenance of urban road green belts, including an umbrella frame 51, a rotating mechanism 1, a water storage mechanism 3, and a spraying mechanism 7. The rotating mechanism 1 is provided with universal wheels 2 at its lower end, the water storage mechanism 3 is fixedly connected to the upper end of the rotating mechanism 1, the lifting mechanism 4 is fixedly connected to the upper end of the water storage mechanism 3, the spraying mechanism 7 is fixedly connected to the upper end of the lifting mechanism 4, and the spraying mechanism 7 is connected to a sunshade cloth 5 through several umbrella frames 51 at its upper end.

[0023] In use, first, the device is moved to the location requiring irrigation using the casters 2. Then, water is injected into the water storage mechanism 3. Next, the shade cloth 5 is unfolded to a suitable angle using the spraying mechanism 7. Then, the internal structure of the lifting mechanism 4 is adjusted according to the height of the plants to be irrigated. The lifting mechanism 4 drives the spraying mechanism 7 to rise and fall to a suitable height. Then, the internal drive structure of the water storage mechanism 3 is activated, causing the spraying mechanism 7 to irrigate the plants. At the same time, the internal drive structure of the rotating mechanism 1 is activated, causing the spraying mechanism 7 to rotate, thereby achieving the purpose of rotating spraying. When the shade cloth 5 is unfolded, the upper middle part of the shade cloth 5 is concave due to the action of the internal structure of the spraying mechanism 7, allowing rainwater to be collected on rainy days. The rainwater enters the lifting mechanism 4 through the filter screen 6, and then enters the water storage mechanism 3 for storage, so that the water can be recycled and reused normally by the water storage mechanism 3.

[0024] Preferably, the rotating mechanism 1 includes a fixed frame 11 and a motor 13. The motor 13 is installed in the fixed frame 11 and its output shaft is connected to a turntable 12 that is rotatably connected to the fixed frame 11. When the motor 13 is started, it drives the turntable 12 to rotate on the upper end of the fixed frame 11, thereby causing the turntable 12 to drive the entire device to rotate.

[0025] In addition, the water storage mechanism 3 includes a water tank 31 and a water pump 34. The water tank 31 is located on the upper end of the turntable 12. A square tube 36 is connected to the water tank 31, passing through the upper end of the water tank 31 and extending to the outside. A support plate 32 is provided on the upper part of the inner cavity of the water tank 31. A through hole 35 located at the bottom of the square tube 36 is opened on the support plate 32. The water pump 34 is installed on the upper end of the support plate 32. The suction pipe of the water pump 34 extends into the water tank 31. The delivery pipe of the water pump 34 passes through the perforated plate 37 inside the square tube 36 and is connected to the lower end of the elastic tube 38. A water inlet pipe 33 is also provided on the support plate 32.

[0026] Water is injected directly into the inner cavity of the water tank 31 from the top of the water inlet pipe 33. Then, the water pump 34 is started. The water pump 34 pumps the water at the bottom of the inner cavity of the water tank 31 and sends it upward from the elastic pipe 38. Then, the water is sprayed out by the spraying mechanism 7 for irrigation. When the rainwater collected above the shade cloth 5 is filtered through the filter screen 6, it enters the interior of the lifting mechanism 4. Then, it enters the inner cavity of the square tube 36 through the lifting mechanism 4. Finally, it falls directly into the bottom of the inner cavity of the water tank 31 through the holes on the perforated plate 37 for collection.

[0027] Specifically, in order to achieve the purpose of adjusting the height of the device, the lifting mechanism 4 includes a square box 41 and a slide tube 43. The square box 41 is disposed on the square tube 36, and the slide tube 43 is slidably connected to the inner cavity of the square tube 36. A rack 44 is provided on the outer side of the slide tube 43. A gear 46 is rotatably connected to the square box 41 through a rotating rod 45. The gear 46 meshes with the rack 44 through a hole 42 opened on the square box 41. A worm 48 is also rotatably connected to the square box 41, and the worm 48 meshes with a worm wheel 47 on the rotating rod 45.

[0028] The rotating disk 12 on the left side of the rotating box 41 drives the worm gear 48 to rotate, the worm gear 48 drives the rotating rod 45 to rotate, and the rotating rod 45 drives the gear 46 to rotate. Then the gear 46 drives the rack 44 meshing with it to rise in the inner cavity of the square tube 36, and then drives the slide tube 43 to rise to achieve the purpose of adjusting the height.

[0029] As the slide tube 43 rises, it simultaneously pulls the elastic tube 38 to contract, causing the elastic tube 38 to lengthen as the height increases. At the same time, the inner diameter of the elastic tube 38 decreases. However, the material of the elastic tube 38 prevents it from becoming sealed while its inner diameter decreases, allowing the water source to still move upward through the inner cavity of the elastic tube 38.

[0030] Preferably, the spraying mechanism 7 includes a support pipe 71, which is located at the upper end of the sliding pipe 43. A filter screen 6 is provided in the middle of the sunshade cloth 5 on the support pipe 71. Several umbrella frames 51 are arranged in a ring on the support pipe 71. Each umbrella frame 51 has a nozzle 73 at the lower middle part. A branched hose 72 connected to the elastic tube 38 is provided inside the support pipe 71. The branches on the branched hose 72 are respectively connected to the corresponding nozzles 73.

[0031] The umbrella frame 51 mentioned above only needs to be able to open the sunshade cloth 5, which is a common structure in the prior art, and will not be described in detail in this utility model.

[0032] By unfolding the umbrella frame 51, several nozzles 73 are dispersed as the umbrella frame 51 unfolds. Water is then sent into the inner cavity of the branched hose 72 through the elastic tube 38, and then into the nozzles 73 through the inner cavity of the branched hose 72, so that the nozzles 73 can spray the plants. While unfolding, the umbrella frame 51 is driven to rotate, so that the umbrella frame 51 can drive the nozzles 73 to spray the plants at different angles when unfolding.

[0033] When the device is finished being used, the entire device can be adjusted to its lowest angle, and the sunshade cloth 5 can be folded vertically to make it easy to move.

[0034] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
