We focus on the research and development and design of agricultural drones,  We are professional service provider focusing on the field of agricultural unmanned aerial vehicles (UAVs). With the core mission of "empowering modern agriculture and improving planting efficiency", we have deeply engaged in the field of intelligent agricultural equipment for many years, providing farmers, cooperatives, and agricultural service enterprises with agricultural UAV products and operation solutions suitable for multiple scenarios. Core Agricultural UAV Products Focusing on agricultural production needs, the company has built an agricultural UAV system covering different operation scales. The core products are characterized by large capacity, high efficiency, and easy operation: Multi-specification Capacity Spraying UAVs: Covering an operation capacity range of 10L-70L, they are suitable for spraying needs from small-scale orchards and vegetable plots to large-scale farmland. The UAV body is equipped with a precise flow control system, which can achieve uniform pesticide spraying per mu (a Chinese unit of area, 1 mu≈0.0667 hectares) and reduce pesticide loss by 20%. Some models support variable-rate spraying technology, which can dynamically adjust the amount of pesticide according to crop growth. With outstanding operation efficiency, a single UAV can complete spraying on 15-20 mu of farmland per day, far exceeding manual efficiency. At the same time, adopting a modular design, vulnerable parts such as nozzles and filters can be replaced easily without professional tools, minimizing equipment downtime. Multi-functional Seeding UAVs: Also covering the 10L-70L capacity range, they are designed for seeding scenarios of various crops such as rice, wheat, and rapeseed. Equipped with an anti-clogging feeding structure and a uniform sowing system, the error of seeding density is less than 5%, and the efficiency is 3-5 times higher than manual seeding. A single UAV can cover more than 20 mu of contiguous farmland per day. The equipment supports alternate use of two batteries, and the dedicated battery compartment design enables seamless replacement of batteries (taking out the old one and installing the new one), eliminating the need to wait for charging and ensuring continuous operation during the busy agricultural season. "Operation + Management" Supporting Solutions: The UAVs can be matched with agricultural operation management software, which supports functions such as operation trajectory recording, area statistics, and pesticide dosage calculation, helping users accurately control the operation progress and costs. Meanwhile, dedicated maintenance accessories and vulnerable part sets are provided, combined with the convenient part replacement design, further lowering the threshold for equipment maintenance.
