Adjustable 1.5-2.5 inch internal thread long-range water spray gun for agricultural farm irrigation.
Detailed Description and Specifications
The 1.5-inch rain gun irrigation sprinkler is a medium-to-large flow agricultural sprinkler designed for efficient water distribution over wide farming areas. It is widely used in field irrigation, pasture watering, and dust suppression systems.
The 1.5-inch rain gun operates under medium to high water pressure and delivers a uniform spray pattern that simulates natural rainfall. It provides good coverage efficiency while maintaining stable performance and easy operation. This size is commonly chosen for small to medium-scale irrigation projects where flexibility and mobility are required.
Adjustable Angle Design: The spray angle can be flexibly adjusted 360°, meeting the irrigation needs of different crops and plots.
Uniform Spraying: Adopts an optimized nozzle structure for uniform water distribution, effectively avoiding local water accumulation or water shortage.
Durable Material: Made of high-quality aluminum alloy + zinc alloy, it is wear-resistant and corrosion-resistant, ensuring a long service life.
Water-saving & Efficient: Reduces water waste while ensuring irrigation effect, conforming to the concept of modern water-saving agriculture.
Easy Operation: Simple installation and disassembly, with low maintenance cost.

Suitable for irrigation of field crops (such as wheat, corn, potatoes, etc.).
Cash crop planting areas such as orchards, tea gardens, and pastures.
Urban greening projects such as landscape greening and lawn maintenance.
Can be used in various agricultural and industrial scenarios such as frost prevention, dust prevention, and cooling.
Effectively improves crop emergence rate and yield, and enhances crop growth.
Improves water resource utilization rate, saving 30%-50% more water than traditional flood irrigation.
Reduces labor costs and improves irrigation automation and management efficiency.
Improves soil structure, avoiding compaction and nutrient loss caused by flood irrigation.

Rain Gun irrigation and Drip Irrigation are two widely used irrigation methods in agriculture. Each system serves different crop types, land conditions, and water management goals.
Rain Gun irrigation works by spraying water at high pressure, simulating natural rainfall over a large area. It is suitable for open fields and large-scale farming where fast and wide coverage is required.
Drip Irrigation delivers water directly to the plant root zone through pipes and emitters. It is a highly efficient method designed for precise water control and water-saving agriculture.
| Item | Rain Gun Irrigation | Drip Irrigation |
|---|---|---|
| Coverage Area | Large-scale (wide radius spraying) | Small-scale (localized root zone) |
| Water Application | Sprays water like rainfall | Delivers water drop by drop |
| Water Efficiency | Medium | Very high |
| Installation Cost | Lower | Higher |
| Maintenance | Simple | Moderate (risk of clogging) |
| Suitable Terrain | Open fields, grassland | Greenhouses, orchards, row crops |
| Operating Pressure | Medium to high | Low |
| Labor Requirement | Low | Low |
Large-scale farmland (wheat, corn, sugarcane)
