The garden metal rocker arm spray gun is an irrigation equipment widely used in fields such as landscaping, farmland irrigation, and sports field maintenance. Its core feature is to achieve automatic rotation of the nozzle through a metal rocker arm structure, thereby expanding the irrigation range and improving uniformity. The following are its detailed characteristics and analysis:
1. Core structural features
Metal rocker arm design materials: usually made of metal materials such as aluminum alloy, stainless steel, or galvanized steel, which have high strength, corrosion resistance, and impact resistance, and can adapt to long-term outdoor use.
.Function: The rocker arm connects the nozzle and the bracket through bearings or hinges, and uses water flow reaction force or mechanical springs to drive the nozzle to rotate 360 ° or fan-shaped, without the need for external power supply or complex transmission devices.
. Advantages: Compared to plastic rocker arms, metal rocker arms are more durable and less prone to breakage due to UV aging or mechanical stress, especially suitable for high-frequency use scenarios.Adjustable nozzle spraying mode: Supports full circle rotation, fan-shaped spraying, or fixed-point spraying. The mode can be switched by rotating the nozzle cover or adjusting the baffle to meet different irrigation needs (such as lawns, flowers, and shrubs).
. Range and flow rate: The nozzle diameter and pressure can be adjusted, with a range of 3-15 meters and a flow rate range of 0.5-10 m ³/h. It is suitable for small-scale fine irrigation or large-scale coverage. Anti clogging design filter structure: The nozzle is integrated with a stainless steel filter inside, which can filter impurities (such as sand and algae) in water and reduce the risk of clogging. Easy to disassemble and clean: The nozzle assembly adopts a quick connect design, which can be quickly disassembled for cleaning or replacing the filter screen, making maintenance convenient.II. Performance Advantages
High Irrigation Uniformity Rotating Spray: By driving the nozzle with a rocker arm to rotate at a constant speed, the water flow covers the area in a spiral shape, avoiding the "dry and wet spots" phenomenon caused by traditional fixed nozzles. The irrigation uniformity can reach over 85%.
. Overlapping coverage: When using multiple spray guns in combination, the overlapping range design ensures that there are no omissions in the edge area, making it suitable for large-scale uniform irrigation. High precision control of water-saving efficiency: With the help of a pressure regulating valve, the spray pressure and flow rate can be adjusted according to crop needs, reducing water evaporation and runoff losses. Low pressure operation: Some models support low pressure operation (0.2-0.5MPa) to reduce energy consumption and are suitable for areas with insufficient water source pressure. Strong wind resistance heavy-duty base: The metal bracket is equipped with a weighted base or ground anchor, which can resist 5-6 levels of wind and prevent the spray gun from tipping or shifting. Low elevation design: The nozzle angle can be adjusted (usually 0 ° -25 °) to reduce the interference of wind on water flow and improve irrigation accuracy.III. Wide application scenarios
Irrigation of garden greening lawns: The full circle rotation mode can evenly cover large lawns and reduce the frequency of manual movement of nozzles.
.Flowers and shrubs: Fan shaped spray mode can be used for directional irrigation, avoiding water flow from washing delicate plants.
. Irrigation of farmland for vegetable cultivation: The low-pressure micro spray mode can simulate natural rainfall and reduce mechanical damage to seedlings. Orchard irrigation: The adjustable range design can penetrate the tree crown and directly irrigate the root area. Special scenario sports field maintenance: High pressure jet can quickly clean large areas of fields such as football fields and golf courses. Cooling and dust removal: In mining and construction sites, water mist spraying is used to reduce temperature and suppress dust.IV. Installation and Maintenance Convenience
Quick Installation Interface Compatibility: Supports standard threaded interfaces (such as 1/2 ", 3/4"), which can be directly connected to PVC pipes, PE pipes or quick couplings without the need for professional tools.
.Angle adjustment: The bracket is equipped with a universal ball head, which can flexibly adjust the pitch and rotation angle of the spray gun to adapt to terrain fluctuations.
. Low maintenance cost corrosion-resistant coating: The metal surface is treated with spray coating or electroplating, which can resist the corrosion of chemical substances such as fertilizers and pesticides. Modular design: Components such as nozzles, rocker arms, and brackets can be replaced separately, reducing maintenance costs.Fifth, Economy and Environmental Protection
Long term low cost and long service life: The service life of metal materials can reach 5-10 years, much higher than that of plastic spray guns (2-3 years), and the overall cost is lower.
. Energy and Water Conservation: Precise irrigation reduces water waste and meets the requirements of agricultural water-saving subsidy policies.Recyclability of environmentally friendly materials: Metal parts can be 100% recycled and reused, reducing environmental pollution.
.Non polluting operation: No need for electricity or fuel to drive, no carbon emissions during operation.
.VI. Limitations and Improvement Directions
The initial cost is higher for metal materials and precision machining, resulting in a higher price than plastic spray guns, but long-term use can dilute costs.
.Improvement: Reduce manufacturing costs by optimizing production processes (such as die casting).
.Water quality requirements: Hard water areas are prone to scale formation and require regular cleaning of filters or installation of soft water devices.
. Improvement: Develop self-cleaning nozzle or anti scaling coating technology.Noise problem: High pressure injection may produce noise (60-80dB), which affects the use of residential areas.
. Improvement: Adopting a low-noise nozzle design or adding a silencing device.7. Selection Suggestions
Choose a model for small-scale irrigation according to the scene: choose a lightweight spray gun with a range of 3-5 meters and a flow rate of 0.5-2 m ³/h.
. Large area coverage: Choose heavy-duty spray guns with a range of 8-15 meters and a flow rate of 5-10 m ³/h. Pay attention to the core parameter of working pressure: ensure that the water source pressure matches the requirements of the spray gun (usually 0.2-0.6MPa). Material certification: Priority should be given to products that have passed ISO 9001 quality certification or CE safety certification.The supplier is required to provide a spray uniformity test report for testing the sample performance, and conduct on-site spray tests to verify the range, flow rate, and rotational stability.
