The metal swing arm sprinkler head drives the swing arm to rotate through water flow impact, achieving automatic swing spraying. Its core function is to efficiently and uniformly complete large-scale irrigation tasks, while also having advantages such as strong durability, wide coverage, and strong adaptability. Specifically, it is as follows:

1. Core function: Automatic rotating spraying, achieving uniform irrigation

Water flow driven rotation

The nozzle is internally driven by water flow to impact the deflector and guide plate at the front end of the rocker arm, causing the rocker arm to generate tangential motion force and rotate around the axis. Under the action of the spring, it returns to impact the nozzle, pushing the nozzle to rotate periodically. This process does not require electricity and relies solely on water pressure to achieve full circle or fan-shaped spraying modes.

Wide coverage

The single rotation angle is 3-5 degrees, the rotation period is about 0.2-2.0 seconds, and the range can reach 9.5-22 meters. It is suitable for fixed, semi fixed, and mobile sprinkler systems.

. For example, one nozzle can cover 300 square meters of land (about half an acre), meeting the irrigation needs of large areas such as farmland, orchards, lawns, etc.

2. Structural advantages: Strong durability, adaptable to complex environments

Material corrosion resistance

The main body is made of all copper, zinc alloy or aluminum alloy casting, forming a dense oxide film on the surface, which can resist acid, alkali and salt erosion.

. For example, all copper nozzles have been tested for 5 years without corrosion in saline alkali land in Shandong, making them suitable for long-term use in arid northern regions.

Anti sand and anti-wear design

Equipped with H-type wear-resistant sealing gasket, spring protection cover, and channel liner to prevent sand and dust from entering and extend service life.

. Some models use ball thrust bearings and V-shaped radial seals to further reduce friction losses.

Wind and earthquake resistance performance

The nozzle speed is stable and easy to adjust, and the spray water volume is evenly distributed, which can reduce the impact of wind speed on irrigation quality.

. For example, it can still maintain a high degree of sprinkler uniformity below level 3 wind.

III. Application scenarios: covering various outdoor irrigation needs

Agricultural irrigation

Widely used in fields such as sprinkler irrigation, open-air nurseries, fruit and vegetable gardens, etc., supporting the irrigation needs of crops such as wheat and corn during their growth cycle.

. For example, the all copper rocker arm nozzle adopts a dual-mode nozzle of "atomization+columnar". During the jointing stage of wheat, columnar water has strong penetration power, and atomized water for lawn maintenance does not damage the grass, saving 50% water compared to flood irrigation.

Landscape

Suitable for buried sprinkler systems to avoid human damage during pruning operations and reduce the risk of animal collisions.

. The spraying angle can be freely adjusted (such as 180 °/270 °/360 °), accurately covering irregular terrain such as slopes and terraces.

Sports facilities

Meet the uniform irrigation needs of large lawns such as football fields and golf courses, support low-pressure start-up (0.15MPa can work), and adapt to various water sources such as well water, river water, and reservoir water.

.

Fourth, added value: labor-saving and efficient, reducing maintenance costs

Automated operation

Built in centrifugal force drive device, automatically rotates 360 ° after connecting to the water source, without manual intervention throughout the process, saving time and cost.

. For example, users of vegetable greenhouses in Shouguang, Shandong have reported that they save time in managing pests and diseases after installation.

Low failure rate design

Key components such as rocker arms and shafts are made of high-strength materials, with steel reinforcement rings added at the bottom to prevent deformation when dropped from a height of 1 meter.

. The brand provides a 5-year warranty, with free replacement of vulnerable parts and a 7-day no reason return policy.

Energy and Water Conservation

By optimizing the spraying mode to reduce water evaporation and loss, water can be saved by 30% -50% compared to traditional irrigation methods, which meets the sustainable development needs of modern agriculture.
