TECHNICAL FIELD
[0001] The utility model relates to the field of landscaping, especially a spraying device for urban landscaping. BACKGROUND
[0002] Urban landscaping aims to improve the ecological environment and enhance the livability of the city by scientifically configuring plants and landscape facilities. As a core tool, the spraying device realizes efficient water saving, uniform coverage, multifunctional integration, and intelligent management through intelligent nozzle design, precise irrigation technology, and automatic control. Especially in the face of large-scale greening needs, it can not only reduce labor costs and save water resources by 30%-50%, but also improve adaptability through mechanical structure optimization such as retractable nozzles and double-drive rotating systems, becoming a key support for the sustainable development of urban greening.
[0003] The existing urban landscaping spraying device is mainly divided into three types: fixed, mobile, and intelligent. The fixed type realizes uniform spraying through pressure diffusion of refractive nozzles or impeller or gear drive of rotary nozzles, relying on pipe network or booster pump for water supply. The mobile type such as water spraying car and hand-push equipment realizes flexible irrigation by water pump pumping water from the water storage tank. The intelligent type integrates soil humidity, meteorological sensors, and combines with automatic control system to dynamically adjust spraying time and water quantity, realizing precise water saving. The three types together meet the needs of different scenes, balancing efficiency, flexibility, and intelligent management.
[0004] In the practical application of the urban landscaping spraying device, the existing equipment generally has the technical bottleneck of relying on manual intervention for height adjustment function. Traditional mechanical nozzles usually adopt fixed supports or multi-stage telescopic rod structures, and the operator needs to manually adjust the height of the supporting screw rod through tools such as wrenches and screwdrivers. This operation mode is particularly inefficient when facing complex terrain, and the operator needs to repeatedly adjust the nozzle elevation angle and vertical height to ensure that the coverage range matches the plant canopy. In addition, the traditional equipment lacks dynamic response capability, and after heavy rain, when the soil humidity is saturated, it cannot automatically reduce the nozzle height to reduce ineffective spraying, further exacerbating water resource waste. This technical defect restricts the efficiency of the overall irrigation system. UTILITY MODEL CONTENTS

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the water for spraying first enters the water guide pipe from the inlet pipe, and then enters the extension pipe and the spray pipe. When the water pressure inside the pipe reaches a specific threshold, the extension pipe and the spray pipe expand upward under the action of the water pressure and with the help of the internal sliding column. This achieves the effect of automatically adjusting the spray height of the spray pipe according to the water pressure entering the pipe during the use of the equipment. This avoids the problem of operators having to manually adjust the height of the equipment to control the spray range during the use of the equipment, thereby improving the efficiency of the spraying device used for urban landscaping.
[0024] 2. In this utility model, first grasp the sliding ring and push it inward, so that the sliding column slides out from the inside of the moving groove, thereby unlocking the connecting pipe. Then, grasp the water injection pipe and pull it outward to remove the water injection pipe. This achieves the effect that during the use of the equipment, the water injection pipe can be easily removed from the inside of the water inlet pipe and the equipment can be moved to another location where it is needed. This avoids the problem that the connection between the water inlet pipe and the water injection pipe of the equipment is too complicated and affects the movement of the equipment during use, thereby improving the convenience of the sprinkler device used for urban landscaping.
