Products Description
Big Sprayer Head
Large-Flow Spray Nozzle for High-Output Agricultural Spraying
Unlike standard spray heads, these deliver significantly higher flow rates, greater spray distances, and wider coverage areas. Constructed from durable materials, these spray heads are typically mounted on tractor spray booms, spray guns, or irrigation cannons for efficient application over extensive fields and orchards.
Technical Profiles & Materials
High Flow Capacity – Designed for high-volume application. Large sprayers are compatible with flow rates up to 7.1–8.3 m³/h, ensuring rapid coverage of large areas . Some configurations with a large nozzle deliver 2.0–5.0 GPM with a spray range of up to 40–45 ft .
Extended Spray Range – Capable of reaching distances of 25–30 feet vertically and horizontally, allowing spot spraying from a seated tractor position . Larger irrigation guns achieve spray radii of 65–80 meters .
Adjustable Spray Patterns – Many models feature adjustable brass or zinc alloy nozzles that can be switched from a straight stream for targeted application to a wide mist for broadcast coverage .

Products Application
Agricultural Broadcast Spraying
Large spray heads on tractor-mounted booms (24–132 ft) apply herbicides, fungicides, and fertilizers across large fields. 110° flat-fan nozzles spaced at 30 inches are commonly used for uniform coverage at rates from 7 to 10 gallons per acre .
Orchard & Vineyard
Hollow cone nozzles (disc-core design) produce fine droplets that penetrate dense canopies for insect and disease control. High-pressure guns (up to 800 PSI) with large nozzles provide 40–45 ft spray range for thorough coverage .
Large-Area Irrigation
Big gun sprinklers (75–100 series) irrigate pastures, hayfields, sports turf, and construction sites. Single-jet nozzles produce a concentrated stream for maximum throw, while multi-orifice and rotary designs provide more uniform coverage at shorter ranges .

FAQ
Q: How to select the correct spray pattern?
A:Flat-fan nozzles are best for broadcast herbicide application. Hollow cone nozzles are preferred for insecticides and fungicides where canopy penetration is essential .
Q: What do the nozzle numbers mean (e.g., 11004)?
A: First three digits indicate spray angle (e.g., 110°), last two digits indicate flow rate in US gallons/minute at 40 psi (e.g., 04 = 0.4 GPM). ISO color codes allow quick identification .
Q: What's the MOQ and lead time?
A: MOQ: 100 PCS. Delivery: 7-14 days. Neutral export carton packaging.
