H22 Agricultural Drone: Advanced Power and Intelligent Spraying for Modern Farming
Time：2026-11-10
Overview
Agricultural operations increasingly require equipment that can handle large working areas while maintaining consistent application efficiency. Traditional crop protection and field treatment methods can involve considerable labor, time, and fuel consumption, particularly when farms cover extensive areas or require frequent operations. Agricultural drones provide an alternative by combining aerial mobility with specialized spraying and spreading functions.
Among these solutions, the H22 agricultural drone stands out through its water-cooled fuel-injected engine, intelligent spraying capabilities, and multi-purpose operating design. For Agricultural Drone Manufacturers, developing equipment that balances working efficiency, engine reliability, and operational flexibility is essential. The H22 brings these elements together to support a wider range of agricultural tasks, including pesticide spraying, powder application, fertilizing, seeding, and feed spreading.
A Water-Cooled Fuel-Injected Engine Built for Extended Operations
The power system plays a critical role in determining the working stability and operational continuity of an agricultural drone. The H22 features a pioneering water-cooled, electronically fuel-injected engine designed for demanding agricultural applications.
Its 7.5 kW engine is developed with a stated service life exceeding 1,000 hours, providing a power solution for users who require frequent and extended field operations. Compared with conventional engine arrangements, electronic fuel injection introduces more precise fuel management through computer-controlled operation.
The ECU electronic fuel injection technology supports responsive ignition without unnecessary waiting. It also helps reduce energy consumption, operating noise, and fluctuations in engine performance. These characteristics make the H22 suitable for agricultural environments where dependable power and efficient operation are important.
Intelligent Water-Cooling for Temperature Management
Engine temperature management is essential for maintaining stable performance during extended operation. The H22 incorporates an adaptive water-cooling thermal management system that automatically adjusts cooling activity according to operating temperature.
When the temperature is relatively low, the cooling water pump automatically shuts down to reduce unnecessary power consumption. As the temperature increases, the pump starts automatically and activates the cooling system to help maintain an appropriate operating temperature.
This automatic adjustment reduces the need for manual intervention and allows the power system to respond to changing operating conditions. For agricultural users working through different weather conditions and operational cycles, adaptive thermal management provides an additional level of operational convenience.
High-Efficiency Aerial Operations Across Large Areas
Working efficiency is one of the main considerations when selecting agricultural spraying equipment. The H22 is designed to cover up to 220 acres per hour, helping users complete large-scale field operations more efficiently.
Its spraying system supports a flow rate of up to 4.5 liters per minute, providing controlled liquid application for pesticide spraying and other compatible agricultural treatments. This capability allows operators to manage spraying tasks across different field areas while adjusting operations according to crop requirements.
The drone also features a rated load of 20.5 liters and supports a water tank capacity of up to 22 liters. This configuration is intended to accommodate agricultural spraying requirements while supporting continuous fieldwork planning.
One Platform for Multiple Agricultural Applications
Modern farming involves more than pesticide application. Depending on crop types, growing stages, and field management requirements, agricultural operators may need different equipment for spraying, fertilizing, seeding, or distributing feed.
The H22 is designed as a multi-purpose agricultural platform that supports liquid spraying, powder spraying, fertilizer application, seeding, and feed spreading. This versatility allows users to consider one machine for several agricultural tasks rather than relying exclusively on equipment designed for a single operation.
For farms with diverse production requirements, multi-purpose functionality can improve equipment utilization and simplify agricultural equipment management. Operators can select the appropriate working function according to the specific task and compatible operating configuration.
Reliable Generator and Convenient Starting System
A stable power supply is important for maintaining the operation of an agricultural drone's electrical systems. The H22 is equipped with an aerospace-grade generator featuring a lightweight, self-cooling design. Its stated service life exceeds five years, supporting long-term equipment operation and durability.
Convenience is also considered in the starting and monitoring functions. The electronic starter enables one-click starting, while the automatic shutdown control provides an additional operational feature. A high-precision fuel level sensor monitors gasoline availability and supports automatic return-to-home when the fuel level becomes low.
These functions help operators manage field operations more conveniently and reduce the need for constant manual monitoring.
Fuel Efficiency and Portability for Field Work
Fuel consumption directly influences the operating costs of agricultural machinery. The H22 is designed with an average fuel consumption of approximately 6 liters per hour, with a stated 20% reduction compared with the same period in the previous year.
Its low-noise design also addresses the working environment, while the lightweight construction supports easier handling and transportation. With a stated weight of 8.5 kg, the power unit offers greater portability for users who need to move equipment between different working locations.
Conclusion
The H22 agricultural drone combines an electronically fuel-injected engine, adaptive water-cooling technology, intelligent spraying, and multi-purpose agricultural functionality. Its design addresses several important requirements in modern farming, including extended operating life, efficient field coverage, fuel management, and operational convenience. For agricultural operators and equipment distributors seeking a versatile aerial farming solution, the H22 offers an integrated approach to crop spraying and other essential field applications.
