Description

Technical Field

[0001] This utility model relates to the field of landscaping technology, specifically a water-saving irrigation device for landscaping projects. Background Technology

[0002] Landscaping is something that many parks and scenic areas need to do nowadays. Greening is also a very important part of the process, and irrigation is a crucial step in the process. Irrigated greenery will be more lush and green. Generally, water pipes and water pumps are used for manual irrigation.

[0003] A utility model patent with Chinese patent authorization announcement number "CN219719353U" discloses "a water-saving irrigation device for landscaping. Compared with the prior art, it allows for adjustment of the spray position for irrigation locations at different distances without increasing the spray volume, thus saving water. However, this device has obvious limitations: firstly, the nozzle height is fixed and cannot be adjusted according to actual needs, making it difficult to adapt to irrigation scenarios for plants of different heights; secondly, the plant roots, as the core part for absorbing water and nutrients..." Directly irrigating the area near the roots is the most effective way to supply water. However, this device can only achieve the conventional top-down irrigation mode. When the nozzle sprays water, if it encounters a plant with lush foliage, the water droplets are easily intercepted by the leaves and can only drip down the leaves to the surrounding soil. This water evaporates quickly on the soil surface or flows elsewhere, preventing the plant roots from obtaining sufficient water. To ensure that the plants receive effective irrigation, it is necessary to extend the irrigation time and increase the water supply, which will undoubtedly lead to a large waste of water resources and contradict the original intention of water-saving irrigation. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a water-saving irrigation device for landscaping projects, so as to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A water-saving irrigation device for landscaping projects, comprising a base, a water tank and a battery on the top of the base, an installation cylinder fixed above one side of the water tank by a fixing rod, an electric push rod installed below one side of the water tank, and a gearbox connected to the output end of the electric push rod, two sets of rotating shafts installed inside the gearbox, a swing arm fixed to the bottom of the rotating shaft, a spray channel fixed to one end of the swing arm, and a second nozzle installed at the bottom of the spray channel; a worm gear is provided on the outer surface of the rotating shaft, a servo motor is installed on one side of the gearbox, and a worm is connected to the output end of the servo motor; a lead screw is installed inside the installation cylinder, a threaded sleeve is fitted on the outer surface of the lead screw, a movable frame is fixed to one side of the threaded sleeve, a rotating tube is rotatably connected to the top of the movable frame, a rigid bend is connected to the top of the rotating tube through a rotary joint, and a spray pipe is installed at the bottom of the rotating tube through a multi-port joint, with a first nozzle installed on one side of the spray pipe.

[0006] Furthermore, a water pump is installed on one side of the top of the water tank, and the water inlet of the water pump is connected to a water pumping pipe extending into the water tank. The water outlet of the water pump is connected to a water delivery pipe. One end of the water delivery pipe is connected to a first connecting pipe through a T-joint. One end of the first connecting pipe is connected to a rigid elbow, and the other end of the first connecting pipe is connected to a second connecting pipe through a T-joint. The two ends of the second connecting pipe are respectively connected to two sets of spray channels.

[0007] By adopting the above technical solution, during operation, the water pump draws water from the water tank through the pumping pipe, and then distributes the water through the delivery pipe to the first connecting pipe and the second connecting pipe via a three-way connector. The first connecting pipe connects to a rigid elbow, and the second connecting pipe connects to two sets of spray channels to achieve multi-path water delivery. This design can flexibly allocate water flow to different irrigation components, meet the synchronous needs of foliage spraying and root irrigation, and improve the functionality of the irrigation system and the water resource utilization rate.

[0008] Furthermore, both the first and second connecting pipes are made of rubber hoses, and a flow regulating valve is installed on the first connecting pipe.

[0009] By adopting the above technical solution, the flexible material of the rubber hose allows the pipe to bend freely as the device rotates or swings, avoiding pipe damage caused by rigid connection. The flow regulating valve can adjust the water flow of the first connecting pipe in real time, accurately control the water volume and pressure of the foliage spray, meet the irrigation needs of different plants, and optimize the counter-thrust by adjusting the flow, so that the rotation speed of the rotating pipe is better matched with the spray range, thereby improving the flexibility and energy saving effect of the irrigation system.

[0010] Furthermore, a control panel is installed at the top center of the water tank, and the water pump, battery, servo motor, and electric push rod are all electrically connected to the control panel.

[0011] By adopting the above technical solutions, the operation parameters of each electrical component can be started and stopped with one click through the control panel, realizing intelligent switching of irrigation modes. For example, the servo motor can be remotely controlled to adjust the surrounding angle of the spray channel, and the electric push rod can control the closeness of the spray channel. The battery power supply design makes the device mobile and portable. The integrated layout of the entire electrical control system improves the ease of operation and the degree of automation of the equipment, meeting the precise irrigation needs of different scenarios in garden maintenance.

[0012] Furthermore, a handle is welded to the top of the base, rollers are installed at the bottom of the base, and a rubber sleeve is provided on the outer surface of the handle.

[0013] By adopting the above technical solution, the handle and rollers enable the device to move flexibly, allowing staff to easily move the device around the garden. The rubber sleeve improves grip comfort and reduces fatigue during handling through its anti-slip design. This structure makes the irrigation device suitable for plant maintenance operations in different terrains, enhancing the portability and ease of use of the equipment, and is especially suitable for the mobile irrigation needs of large garden areas.

[0014] Furthermore, the outer surface of the water tank is provided with an observation window, and the other side of the top of the water tank is provided with a water inlet, the inside of which is equipped with a filter screen.

[0015] By adopting the above technical solution, the observation window can be used to check the water level in real time to avoid water shortage, and the water inlet with filter screen can filter impurities in the water to prevent clogging of the nozzles. This design not only facilitates monitoring of the water tank's water storage, but also ensures that the water quality is clean when adding water, reduces malfunctions in the irrigation system caused by impurities, improves the reliability and ease of maintenance of the equipment, and keeps the water tank in a good water supply state to ensure the continuous and stable operation of irrigation.

[0016] Furthermore, the spray pipe is provided in multiple sets, and the multiple sets of spray pipes are arc-shaped, with the first nozzle tilted downward at 35°.

[0017] By adopting the above technical solution, when water is sprayed from the nozzles that are tilted downwards at 35°, the arc arrangement allows the resultant force of the thrust of each nozzle to form a better coupling angle with the rotation axis of the rotating pipe. Compared with the straight spray pipe, the arc design can make the thrust torque distribution more uniform and the rotation state more stable. Moreover, the downward tilt angle ensures that sufficient thrust can be generated, and it is less likely to spray water on the staff.

[0018] Furthermore, the spray channel is provided in two sets, the two sets of spray channels are arc-shaped, and the second nozzle is tilted inward at 45°.

[0019] By adopting the above technical solution, the arc-shaped spray channel can form a semi-enclosed irrigation layout along both sides of the plant stem. The 45° inward tilt angle allows the water flow to be sprayed onto the soil around the roots with the best incident trajectory, achieving precise irrigation of plant roots and efficient water utilization.

[0020] Furthermore, the worm gear is provided in two sets, the worm is located between the two sets of worm gears and meshes with the two sets of worm gears, and the outer surfaces of the worm and worm gears are coated with lubricating oil.

[0021] By adopting the above technical solution, the worm can drive two sets of worm wheels to rotate in opposite directions or in opposite directions when the worm rotates, thereby completing the purpose of two sets of spray channels encircling or expanding. The lubricating oil coating improves the transmission efficiency by reducing the coefficient of friction, so that the driving force of the servo motor can be more efficiently converted into the oscillating kinetic energy of the spray channel, while delaying the oxidation and corrosion of the metal surface and extending the service life of the transmission components.

[0022] Furthermore, the mounting cylinder has an opening on the side near the water tank, and a knob is fixed to the top of the lead screw.

[0023] By adopting the above technical solution, the location of the movable port is far away from the spraying area, which can effectively prevent water from directly contacting the lead screw during spraying operations, prevent the lead screw surface from rusting and corroding due to water residue, and at the same time provide clearance for the threaded sleeve to drive the movable frame to rise and fall; the knob design reduces the turning torque by increasing the operating radius, allowing the operator to easily adjust the lead screw rotation by hand.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model comprises a spray pipe, a first nozzle, a rotary joint, a rotary pipe, a multi-way joint, a spray channel, a servo motor, a worm gear, a worm wheel, a swing arm, an electric push rod, a spray channel, and a second spray. The operator flexibly moves the device to the vicinity of the plant, suspending multiple sets of spray pipes above the plant. Then, the electric push rod is activated, driving the spray channel to quickly approach the lower part of the plant stem along a preset trajectory. Next, the servo motor is activated, causing the worm gear to rotate synchronously. The worm gear drives two sets of worm wheels to rotate, which in turn causes the rotating shaft to drive the swing arm to deflect at an angle, thus causing the spray channel to swing in an arc, ultimately encircling (or relatively encircling, depending on the thickness of the plant stem) the bottom of the plant stem. When the water pump is turned on, water flows at high speed through the water supply pipe into the first connecting pipe, immediately opening a bidirectional flow path: firstly, one end of the first connecting pipe guides the water flow to a rigid elbow, after which the water is guided... The water flows into the rotating pipe, then is diverted through the multi-connector to multiple sets of spray pipes, and finally sprayed out at high speed from multiple sets of first nozzles. The water jet instantly generates a strong counter-force, causing the rotating pipe to rotate with the help of the rotating connector. The rotation of the rotating pipe drives multiple sets of spray pipes to rotate synchronously, forming a 360-degree three-dimensional irrigation mode without dead angles. This greatly expands the coverage area of ​​the foliage spray, not only efficiently cooling the leaves and relieving transpiration pressure, but also powerfully washing away dust on the leaf surface and optimizing the photosynthetic environment of the plants. Secondly, the other end of the first connecting pipe introduces the water flow into the second connecting pipe. After being precisely diverted by the second connecting pipe, it is injected into two sets of spray channels, and finally targeted to the plant roots from the second nozzles. This composite irrigation mode of "foliage spray cooling + precise root drip irrigation" not only ensures the healthy growth of the above-ground parts of the plants, but also ensures that the underground roots receive sufficient water nourishment, effectively improving the efficiency of water resource utilization.

[0026] 2. This utility model also includes a lead screw, a threaded sleeve, and a movable frame. When watering taller plants, the operator can rotate the lead screw. The rotation of the lead screw causes the threaded sleeve to move the movable frame upward, thereby raising the height of the sprinkler pipe. By flexibly adjusting the sprinkler height, the water flow can accurately cover the target area, avoiding irrigation blind spots caused by insufficient height, and greatly improving the flexibility and versatility of garden maintenance operations.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1: A water-saving irrigation device for landscaping projects, such as... Figures 1-6As shown, the system includes a base 1, with a water tank 2 and a battery 24 on its top. An mounting cylinder 13 is fixed to the upper side of the water tank 2 via a fixing rod 12. An electric push rod 14 is installed on the lower side of the water tank 2, and its output end is connected to a gearbox 15. Two sets of rotating shafts 26 are installed inside the gearbox 15, and a swing arm 30 is fixed to the bottom of each rotating shaft 26. A spray channel 31 is fixed to one end of each swing arm 30, and a second nozzle 32 is installed at the bottom of the spray channel 31. A worm gear 28 is provided on the outer surface of the rotating shaft 26. A servo motor 27 is installed on one side of the gearbox 15, and its output end is connected to a worm 29. The worm gear 28 has two... The worm gear 29 is located between two sets of worm wheels 28 and meshes with them. The outer surfaces of the worm gear 29 and worm wheels 28 are coated with lubricating oil. When the worm gear 29 rotates, it drives the two sets of worm wheels 28 to rotate in opposite directions or in opposite directions, thereby achieving the purpose of the two sets of spray channels 31 encircling or expanding. The lubricating oil coating improves transmission efficiency by reducing the coefficient of friction, allowing the driving force of the servo motor 27 to be more efficiently converted into the oscillating kinetic energy of the spray channels 31. Simultaneously, it delays oxidation and corrosion of the metal surface, extending the service life of the transmission components. A lead screw 33 is installed inside the mounting cylinder 13. An opening is provided on the side of the mounting cylinder 13 near the water tank 2. A knob is fixed to the top of the lead screw 33. The opening is located away from... The spray area effectively prevents water from directly contacting the lead screw 33 during spraying operations, preventing rust and corrosion caused by water residue on the surface of the lead screw 33. It also provides clearance for the threaded sleeve 34 to move the movable frame 23 up and down. The knob design increases the operating radius and reduces the turning torque, allowing workers to easily adjust the rotation of the lead screw 33 by hand. The outer surface of the lead screw 33 is fitted with a threaded sleeve 34. A movable frame 23 is fixed to one side of the threaded sleeve 34. A rotating tube 11 is rotatably connected to the top of the movable frame 23. The top of the rotating tube 11 is connected to a rigid bent tube 9 via a rotary joint 10, and a spray pipe 21 is installed at the bottom of the rotating tube 11 via a multi-port joint 20. A first spray head 22 is installed on one side of the spray pipe 21. A water pump 4 is installed on one side of the top of the water tank 2, and the water inlet end of the water pump 4 is connected to a water pumping pipe 5 extending into the water tank 2. The water outlet end of the water pump 4 is connected to a water delivery pipe 6. One end of the water delivery pipe 6 is connected to a first connecting pipe 7 through a T-joint. One end of the first connecting pipe 7 is connected to a rigid elbow, and the other end of the first connecting pipe 7 is connected to a second connecting pipe 8 through a T-joint. The two ends of the second connecting pipe 8 are respectively connected to two sets of spray channels 31. When working, the water pump 4 draws water from the water tank 2 through the water pumping pipe 5, and the water is distributed through the water delivery pipe 6 to the first connecting pipe 7 and the second connecting pipe 8 through the T-joint. The first connecting pipe 7 is connected to the rigid elbow, and the second connecting pipe 8 is connected to the two sets of spray channels 31 to achieve multi-path water delivery.This design allows for flexible water distribution to different irrigation components, meeting the simultaneous needs of foliage spraying and root irrigation, thus improving the functionality and water resource utilization of the irrigation system.

[0037] See Figures 1-6 In the above embodiments, both the first connecting pipe 7 and the second connecting pipe 8 are made of rubber hoses, and a flow regulating valve is installed on the first connecting pipe 7. The flexible material of the rubber hose allows the pipe to bend freely with the rotation or swing of the device, avoiding damage to the pipe caused by rigid connection. The flow regulating valve can adjust the water flow rate of the first connecting pipe 7 in real time, accurately control the water volume and pressure of the foliage spray, meet the irrigation needs of different plants, and optimize the magnitude of the counter-thrust by adjusting the flow rate, so that the rotation speed of the rotating pipe 11 is better matched with the spray range, thereby improving the flexibility and energy saving effect of the irrigation system.

[0038] See Figure 1 In the above embodiment, a control panel 19 is installed at the top center of the water tank 2, and the water pump 4, battery 24, servo motor 27, and electric push rod 14 are all electrically connected to the control panel 19. The control panel 19 can start and stop each electrical component and adjust the operating parameters with one button, realizing intelligent switching of irrigation modes. For example, the servo motor 27 can be remotely controlled to adjust the surrounding angle of the spray channel 31, and the electric push rod 14 can control the close distance of the spray channel 31. The battery 24 power supply design makes the device mobile and portable. The integrated layout of the entire electrical control system improves the ease of operation and the degree of automation of the equipment, meeting the precise irrigation needs of different scenarios in garden maintenance.

[0039] See Figures 1-2 In the above embodiment, a handle 16 is welded to the top of the base 1, and a roller 18 is installed at the bottom of the base 1. The outer surface of the handle 16 is provided with a rubber sleeve. The handle 16 and the roller 18 make the device flexible and mobile, and the staff can easily push the device to move in the garden scene. The rubber sleeve improves the grip comfort through the anti-slip design and reduces fatigue during handling. This structure makes the irrigation device suitable for plant maintenance operations in different terrains, enhances the portability and ease of use of the equipment, and is especially suitable for the mobile irrigation needs of large garden areas.

[0040] See Figure 1 , Figure 2 , Figure 5 and Figure 6In the above embodiment, the spray pipe 21 is provided in multiple sets, and the multiple sets of spray pipes 21 are arc-shaped. The first nozzle 22 is tilted downward at 35°. When the water flow is sprayed from the nozzle tilted downward at 35°, the arc arrangement allows the resultant force direction of the counter-thrust of each nozzle to form a better coupling angle with the rotation axis of the rotating pipe 11. Compared with the straight spray pipe 21, the arc design can make the counter-thrust torque distribution more uniform and the rotation state more stable. Moreover, the downward tilt angle ensures that sufficient counter-thrust can be generated, and it is also less likely to spray water on the staff. The spray channel 31 is provided in two sets, and the two sets of spray channels 31 are arc-shaped. The second nozzle 32 is tilted inward at 45°. The arc-shaped spray channel 31 can form a semi-enclosed irrigation layout along both sides of the plant stem. The 45° inward tilt angle allows the water flow to be targeted and sprayed to the soil around the roots with the best incident trajectory, realizing precise irrigation of the plant roots and efficient use of water.

[0041] Example 2: To prevent impurities in the irrigation water from clogging the sprinkler heads, Example 2 is an improvement on Example 1. (See attached document.) Figure 1 The outer surface of the water tank 2 is provided with an observation window 17, and the other side of the top of the water tank 2 is provided with a water inlet 3. A filter screen 25 is installed inside the water inlet 3. The observation window 17 can be used to check the water level in real time to avoid water shortage. The water inlet 3 and the filter screen 25 can filter impurities in the water to prevent clogging of the nozzles. This design not only facilitates the monitoring of the water storage of the water tank 2, but also ensures the cleanliness of the water when adding water, reduces the failure of the irrigation system caused by impurities, improves the reliability and maintenance convenience of the equipment, and keeps the water tank 2 in a good water supply state to ensure the continuous and stable operation of irrigation.

[0042] The implementation principle of this utility model is as follows: When facing plants of different heights, the operator first rotates the knob at the top of the lead screw 33. Through the transmission between the lead screw 33 and the threaded sleeve 34, the movable frame 23 slides upward along the movable opening of the mounting cylinder 13, ensuring that the spraying height of the arc-shaped spray pipe 21 is adapted to the plant crown width. Then, the device is moved to the side of the plant by the rollers 18 at the bottom of the base 1. The position is adjusted by holding the handle 16 so that multiple sets of spray pipes 21 are suspended above the plant. Then, the electric push rod 14 is activated, and its piston rod extends to drive the spray channel 31 to approach the lower part of the plant. Next, the servo motor 27 on the control panel 19 is activated. The motor drives the worm gear 29 to rotate, and the two worm wheels 28 rotate synchronously and deflect the swing arm 30 through the rotating shaft 26. This drives the spray channel 31 to adapt to the curvature of plant stems of different thicknesses and surround their bottom (for thinner plant stems). The pole can be completely enclosed, while thicker poles can be enclosed in an open manner (without affecting root irrigation). When the staff starts the water pump 4, the water flows through the pumping pipe 5 from the water tank 2 and through the water delivery pipe 6 into the first connecting pipe 7, where it is divided: First, the water flows through the rigid bend pipe 9 into the rotating pipe 11, and is divided by the multi-port connector 20 to the spray pipe 21. When it sprays out from the first nozzle 22 tilted downwards at 35°, it generates a counter-thrust force, driving the rotating pipe 11 to rotate 360° under the support of the rotating connector 10, thus completing the cooling and dust removal of the branches and leaves; Second, the water flows through the second connecting pipe 8 to the spray channel 31, and is targeted to irrigate the roots from the second nozzle 32 tilted inwards at 45°. During this process, the rubber hose material of the first connecting pipe 7 bends freely with the rotation of the device, and the flow regulating valve controls the water pressure.

[0043] The height of this device is adjustable from 0.5 to 1.5 meters, and the spray channel 31 and spray pipe 21 can flexibly wrap around and rotate. It is mainly suitable for low shrubs and medium-sized flowering plants in gardens.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
