The ZB50L-4 agricultural drone utilizes aerospace materials to reduce the structural weight of the drone, thereby extending its service life; it exhibits superior resistance to high and low temperatures, corrosion, and aging; the average service life of the frame is approximately five years. • Wing materials: carbon fiber composite materials (lightweight, durable, corrosion-resistant) • Hardware components: Aluminum alloy (lightweight, durable, corrosion-resistant) • Spray tank: Plastic (corrosion-resistant, aging-resistant) • Propellers: Carbon fiber composite material (wear-resistant, corrosion-resistant) • The core modules are equipped with dedicated protective devices, providing waterproof and dustproof protection. Power system: Brushless motors are used as the power source, which operate without sparks and are not easily damaged. Brushless motors have a service life of more than 1,000 hours and are long-lasting. Spray System: • Chemical Tank: Capacity: 50L; Material: PE plastic Made of EP plastic with carbon fiber protection on the outside; corrosion-resistant and impact-resistant • Spray Nozzles: Quantity: 4 (centrifugal nozzles); Material: Plastic • Impeller Pump: Quantity: 2 units; Normal service life: Over 500 hours
