Description

Technical Field

[0001] This invention relates to the field of garden irrigation technology, and in particular to an intelligent irrigation device and method for garden engineering. Background Technology

[0002] Currently, irrigation is one of the core operations in the maintenance of green belts in landscaping projects. To address the issues of high labor intensity and low efficiency when manually irrigating with handheld sprayers, existing technologies use robotic arms to hold the nozzles and replace manual watering of the plants. The basic movements of the robotic arm, such as swinging and extending, move the nozzles and adjust the spray angle to replenish the vegetation in the green belt.

[0003] In the aforementioned existing technologies, the robotic arm is merely a conventional structure that simply clamps a single nozzle. It lacks a specialized spraying range expansion structure designed for the vegetation distribution characteristics of garden green belts. It can only rely on the basic movements of the robotic arm to drive the nozzle to achieve small-scale watering, failing to achieve comprehensive, all-around spraying coverage of the green belt and easily creating localized watering blind spots. As a result, during actual spraying, staff need to continuously adjust the movement trajectory of the robotic arm to strive for comprehensive spraying. During the frequent movement and adjustment of the robotic arm, the nozzle rotates around, which not only makes it difficult to completely eliminate watering blind spots and achieve comprehensive water replenishment for vegetation, but also causes water to splash around, resulting in ineffective waste of water resources and significant disturbance to pedestrians around the garden. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent irrigation device and method for landscaping projects, solving the problems of existing technologies where the robotic arm simply holds a single nozzle and lacks a specialized spraying range extension structure designed for the vegetation distribution characteristics of green belts. This means the robotic arm can only move the nozzle within a small area for irrigation, failing to achieve comprehensive, blind-spot-free coverage of the green belt and easily creating localized irrigation blind spots. Consequently, during actual spraying, workers must continuously adjust the robotic arm's trajectory to ensure comprehensive coverage. Furthermore, the frequent movement and adjustment of the robotic arm causes the nozzle to rotate, making it difficult to completely eliminate irrigation blind spots and achieve comprehensive vegetation hydration. This also results in water splashing, leading to ineffective waste of water resources and significant disturbance to pedestrians in the surrounding area.

Detailed Implementation

[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0027] Please see Figures 1 to 7 This invention provides an intelligent irrigation device for garden engineering, including a trolley 1, a water tank 2, a control panel 3, two irrigation components, a rotating component, and a lifting component. The water tank 2 is located above the trolley 1, the control panel 3 is located on one side of the water tank 2, the rotating component is located above the trolley 1, the lifting component is located on the rotating component, and the two irrigation components are symmetrically arranged on the rotating component and the lifting component. The irrigation assembly includes an arc-shaped slide rail 4, a slider 5, two arc-shaped spraying units, a telescopic spraying unit, and multiple fixed side plates 6. The arc-shaped slide rail 4 is located above the rotating assembly. The slider 5 is slidably connected to the arc-shaped slide rail 4. The telescopic spraying unit is located on the slider 5. The two arc-shaped spraying units are symmetrically arranged on the telescopic spraying unit. The multiple fixed side plates 6 are sequentially arranged on both sides of the arc-shaped spraying unit.

[0028] In this embodiment, the trolley 1 is moved next to the vegetation, and the lifting assembly is activated to move the irrigation assembly above the vegetation. The telescopic spraying unit extends and retracts, adjusting the distance between the two arc-shaped spraying units to accommodate vegetation of different sizes. The water tank 2 supplies water to the arc-shaped spraying units and the telescopic spraying unit for irrigation. The lifting assembly is activated, causing the slider 5 to move on the arc-shaped slide rail 4. The slider 5 drives the two arc-shaped spraying units and the telescopic spraying unit to move in an arc, causing the spraying path to move around the outside of the vegetation, thus continuously moving to irrigate. The fixed side plate 6 shields the sides of the arc-shaped spraying units to reduce spray splashing. The operator operates the control panel 3 to stop the spraying and moves to the next vegetation to repeat the above operation. By relying on the arc-shaped movement path for spraying, the vegetation is evenly covered during spraying, and the splashing caused by adjusting the nozzle angle at different locations in traditional operations is avoided, significantly improving spraying efficiency and quality.

[0029] Furthermore, the rotating assembly includes a rotating component 7 and a turntable 8. The rotating component 7 is disposed below the trolley 1. The output end of the rotating component 7 passes through the trolley 1 and is fixedly connected to the turntable 8. The turntable 8 is rotatably connected to the top of the trolley 1. The arc-shaped slide rail 4 is disposed above the turntable 8.

[0030] In this embodiment, the rotating component 7 drives the turntable 8 to rotate, thereby adjusting the spray angle above.

[0031] Furthermore, the lifting assembly includes a screw motor 9, a threaded plate 10, two sliding plates 11, two connecting shafts 12, and two rotating shafts 13. The screw motor 9 is positioned above the turntable 8 and between the two arc-shaped slide rails 4. The threaded plate 10 is adapted to the screw motor 9 and has two sliding grooves 14. The two sliding plates 11 are slidably connected to the corresponding sliding grooves 14. The two rotating shafts 13 are fixedly mounted on one end of the corresponding sliding plate 11. The two connecting shafts 12 are fixedly mounted on the corresponding sliders 5. One end of the two connecting shafts 12 is fixedly connected to the corresponding telescopic spraying unit, and the other end of the two connecting shafts 12 is rotatably connected to the corresponding rotating shafts 13.

[0032] In this embodiment, the screw compressor 9 is started, which drives the threaded plate 10 to move up and down. The threaded plate 10 drives the slide plate 11 to move. The slide plate 11 drives the connecting shaft 12 to move. The connecting shaft 12 drives the rotating shaft 13 to move. Then the rotating shaft 13 drives the slider 5 to slide on the arc-shaped slide rail 4, thereby causing the arc-shaped spraying unit to move to both sides to achieve the effect of arc-shaped spraying.

[0033] Furthermore, the telescopic spraying unit includes a telescopic chamber 15, multiple external nozzles 16, a telescopic plate 17, a telescopic spraying cylinder 18, multiple internal nozzles 20, and a telescopic drive mechanism.

The multiple internal nozzles 20 are respectively arranged inside the corresponding through holes 21. The telescopic drive mechanism is arranged outside the telescopic chamber 15.

[0034] In this embodiment, before spraying, the telescopic drive mechanism is activated to move the telescopic plate 17 away from the telescopic chamber 15, thereby adjusting the spraying length. After the spraying distance increases, the telescopic spraying cylinder 18 extends out of the telescopic chamber 15. At this time, the internal nozzles 20 are moved out, thereby increasing the spraying area. Conversely, the spraying area is reduced. When all the internal nozzles 20 are located inside the telescopic chamber 15, spraying is performed through the external nozzles 16.

[0035] Furthermore, the telescopic drive mechanism includes a telescopic component 23 and a telescopic connecting block 24. The telescopic component 23 is disposed above the telescopic chamber 15, and the telescopic connecting block 24 is disposed above the telescopic plate 17. The output end of the telescopic component 23 is fixedly connected to the telescopic connecting block 24.

[0036] In this embodiment, the telescopic component 23 is a self-locking cylinder, which, when activated, drives the telescopic connecting block 24 to move, thereby achieving the purpose of telescopic adjustment.

[0037] Furthermore, the arc-shaped spraying unit includes an arc-shaped spray chamber 25, multiple arc-shaped nozzles 26, an angle adjustment component 27, and a shielding mechanism.

The output end of the angle adjustment component 27 is fixedly connected to the arc-shaped spray chamber 25. The multiple arc-shaped nozzles 26 are sequentially disposed on the arc-shaped spray chamber 25, and the shielding mechanism is disposed at the other end of the arc-shaped spray chamber 25.

[0038] In this embodiment, the arc-shaped spray chamber 25 is used to store spray water, which is then sprayed out from the arc-shaped nozzle 26 to achieve the spraying purpose. When spraying, the angle adjustment component 27 is activated to drive the arc-shaped spray chamber 25 to rotate, which can also adjust the curvature to adapt to different vegetation.

[0039] Furthermore, the shielding mechanism includes a shielding plate 28 and a shielding driving component 29. The shielding driving component 29 is disposed at the other end of the arc-shaped spray chamber 25, and the output end of the shielding driving component 29 is fixedly connected to the shielding plate 28.

[0040] In this embodiment, the shielding drive component 29 is activated, driving the shielding plate 28 to rotate and unfold, thereby shielding both ends of the arc-shaped spray chamber 25 and reducing water splashing.

[0041] Furthermore, the irrigation assembly also includes a water delivery unit, which is disposed on the rotating shaft 13; The water supply unit includes a water pump 30, a water pumping hose 31, a water outlet 32, an upstream hose 33, a first diversion pipe 34, a second diversion pipe 35, two diversion mechanisms, and a connecting pipe 36.

One end of the water pumping hose 31 is detachably connected to the water outlet 32, and the other end of the water pumping hose 31 is connected to the water inlet of the water pump 30. The two ends of the upstream hose 33 are respectively connected to the water outlet of the water pump 30 and the flow groove 37. The two ends of the first diversion pipe 34 are respectively connected to the flow groove 37 and the telescopic chamber 15.

The two diversion mechanisms are respectively located on the telescopic plate 17 and the telescopic chamber 15, and the two diversion mechanisms are connected to each other through the connecting pipe 36.

[0042] In this embodiment, when spraying, the water source enters the pumping hose 31 through the outlet 32, then passes through the pump 30 to the upstream hose 33, and then enters the flow channel 37. After passing through the first diversion pipe 34 and the second diversion pipe 35, the water source enters the telescopic chamber 15 and the diversion mechanism respectively. After reaching the telescopic chamber 15, the water source can enter the telescopic spray cylinder 18 through the through hole 21, and then be sprayed out from the internal nozzle 20. After entering the diversion mechanism, the water source enters another diversion mechanism through the connecting pipe 36, thereby supplying water to the two arc-shaped spray chambers 25.

[0043] Furthermore, the diversion mechanism includes a diversion chamber 38 and a third diversion pipe 19. The diversion chamber 38 is disposed on one side of the telescopic chamber 15. The two ends of the third diversion pipe 19 are respectively connected to the diversion chamber 38 and the arc-shaped spray chamber 25. The two diversion chambers 38 are connected to each other through the connecting pipe 36.

[0044] In this embodiment, the water source reaches the diversion chamber 38 through the second diversion pipe 35, and then reaches the interior of the arc-shaped spray chamber 25 through the third diversion pipe 19.

With the above-mentioned structural design, spraying is carried out by relying on an arc-shaped movement path, which ensures that the vegetation is evenly covered during spraying and avoids the splashing caused by adjusting the nozzle angle at different locations in traditional operations, thus significantly improving spraying efficiency and quality.
