This drone offers efficient, precise spraying capabilities, tailored for large-scale crop management with stability and durability in demanding agricultural environments.

BACKGROUND OF THE INVENTION

Agriculture has increasingly turned to advanced technology to meet the demands of large-scale crop management. Traditional methods of crop spraying can be labor-intensive, time-consuming, and imprecise, often leading to uneven application, crop damage, and inefficient use of resources. With the advent of artificial intelligence and robotics, agricultural drones have emerged as a promising solution for precise and efficient crop spraying. However, many existing drones on the market still face limitations that restrict their effectiveness, especially when operating over large fields or carrying heavier liquid payloads.

Existing agricultural spraying drones, such as the JMR-X1100, have notable constraints. While configured as a quadcopter with a maximum takeoff weight of 13 kg and a battery capacity of 1*6s 12000 mAh, these drones exhibit restricted payload capacity, limited battery life, and reduced endurance. Additionally, their fragile frame construction and inadequate landing mechanisms make them vulnerable to wear and damage, particularly in rugged agricultural environments. This shortfall in structural robustness and operational capability restricts the drone's efficiency and lifespan, leading to increased maintenance and replacement costs for users.

The present invention addresses these issues by introducing a Quadcopter with Twin Nozzle for High Precision 5-Liter Agriculture Spraying, designed to provide significant improvements in payload capacity, battery support, and endurance. Constructed with a robust, aviation-grade 6061 aluminum frame, the proposed drone can withstand the demanding conditions of large-scale agricultural fields. Its large payload capacity and substantial battery support allow it to cover more ground with fewer interruptions, significantly enhancing operational efficiency. The high-clearance design of the elevated arms minimizes the risk of crop damage while improving maneuverability and stability. This design also facilitates easier maintenance and optimized payload distribution, further enhancing the drone's performance and reliability.

Additionally, the drone is equipped with a shock-absorbing landing mechanism, reducing impact forces during landing and enhancing durability. This feature not only increases the longevity of the frame but also reduces maintenance needs following rough landings. These improvements, along with the drone’s dual-nozzle configuration for precision spraying, distinguish the proposed invention from prior models. By combining durability, stability, and enhanced payload capabilities, the invention fulfills the need for a more efficient and robust agricultural spraying solution, capable of addressing the shortcomings found in prior art.

Figures 1 and 2 show an agriculture spraying drone (AgROW Quadcopter) that is constructed in accordance with a preferred embodiment of the present invention. Figure 1 and 2 illustrates the external schematic view of the AgROW Quadcopter from front side and rear side respectfully. The present invention, the AgROW Quadcopter, is a specialized agriculture spraying drone developed for efficient, high-precision crop treatment. Built to handle large-scale operations, it integrates a suite of advanced features to improve its endurance, durability, payload capacity, and operational stability. The invention addresses common challenges faced in agricultural spraying, providing a robust, reliable solution that enhances productivity while reducing downtime and maintenance.

Structure and Configuration
At the core of the AgROW Quadcopter’s design is a chassis assembly crafted from aviation-grade 6061 aluminum and reinforced with carbon fiber. This combination gives the drone structural integrity, allowing it to withstand the stresses of heavy-duty agricultural work without adding unnecessary weight. The chassis consists of:

Four arms (6), extending outward from the central body in a balanced quadcopter formation. Each arm supports a motor and propeller, providing symmetrical lift and thrust. The arms are further reinforced with arm rings (19), which secure them in place and minimize vibrations during flight, protecting the frame and reducing wear on essential components.
A protective canopy (4) that houses internal electronics, such as the GPS and flight controller. This canopy not only shields these components from environmental factors but also reduces air resistance, improving the drone’s stability and performance.

The structure is designed with optimal weight distribution, maintaining balance even when carrying a full payload. This careful configuration of components enhances stability, maneuverability, and durability, allowing the AgROW Quadcopter to operate reliably across rough terrains and withstand the demands of repeated use in agricultural environments.

Propulsion and Flight Stability
The AgROW Quadcopter’s propulsion system is engineered for reliable, consistent thrust, ensuring smooth, stable flight even with heavy payloads. Key features of the propulsion system include:

High-efficiency BLDC motors (8), each mounted on the end of an arm, powering propellers (7) that generate the necessary lift and forward thrust. These motors are designed for minimal energy consumption while providing the power required for efficient operation, extending the drone’s flight time and reducing energy costs.

Arm mounts (5) that connect each arm securely to the main frame. These mounts provide a solid structural foundation for the arms and motors, distributing the stress evenly and ensuring the drone remains stable in flight, even under adverse conditions.

The propellers are arranged in a balanced configuration to create consistent lift, reducing the likelihood of drift or imbalance. This setup allows the AgROW Quadcopter to navigate fields with high precision, maintaining an even altitude above crops, which is essential for uniform spraying. The carefully designed propulsion system enables the drone to move smoothly and remain steady, even when environmental factors, such as wind, come into play.

Navigation and Control System
The AgROW Quadcopter integrates a sophisticated navigation and control system that enables precise, autonomous operation. This system enhances the drone’s usability and ensures that it performs consistently, even over large fields. Key components of the navigation and control system include:

A GPS system (3), centrally mounted on a GPS mount (2), that provides accurate location data, essential for precise navigation and waypoint tracking. By utilizing GPS coordinates, operators can pre-program routes or adapt them in real time to ensure thorough crop coverage without missing areas or overlapping.

Receiver antenna (1) allows for long-range communication with the operator, enabling real-time control and adjustments. This antenna is critical for maintaining strong, stable connections, allowing the operator to make responsive, on-the-fly changes to the drone’s flight path or spray parameters as needed.

A flight controller (not explicitly numbered) that manages all aspects of flight, from motor control to altitude adjustments. It continuously monitors inputs from the GPS and other sensors to maintain stable flight and ensure the drone adheres to the programmed route. The flight controller also controls the timing and flow rate of the spray system, ensuring that application is consistent throughout the flight.

Together, these navigation components allow the AgROW Quadcopter to follow pre-defined routes autonomously, reducing the need for operator intervention and increasing efficiency. The navigation system also enables adaptive control, so the drone can make minor course adjustments based on real-time conditions, such as variations in terrain or obstacles.

Power System and Battery Support
The AgROW Quadcopter is equipped with a battery system (12) designed to maximize flight duration, allowing it to cover large areas on a single charge. This extended endurance reduces downtime and increases operational efficiency. The battery system includes:

Battery plugs (17) that create secure electrical connections, preventing accidental disconnections during flight. These plugs ensure a consistent power supply, which is crucial for sustained operation.
A battery stand (18) that holds the battery in place within the frame, minimizing movement during flight and maintaining a stable center of gravity. The battery stand also reduces strain on internal wiring, protecting it from wear caused by vibration.
The high-capacity battery not only powers the flight but also supports the spray mechanism, allowing for seamless operation without interruptions. The battery system’s design supports easy removal and replacement, allowing operators to quickly switch batteries between flights, which further improves efficiency during intensive spraying schedules.

Precision Spraying Mechanism
The AgROW Quadcopter’s primary function—precision spraying—is made possible through its advanced spraying mechanism. This mechanism is engineered to provide accurate, efficient application of treatments, such as fertilizers or pesticides, across a wide area, with minimal waste. The spraying mechanism includes:

A liquid tank (10) with a 5-liter capacity, allowing for significant payloads that reduce the need for frequent refilling. This high-capacity tank is essential for large-scale fields, where stopping to refill would otherwise hinder productivity.

A flowmeter (11) and liquid pump (16), mounted on a pump mount (15), that work in tandem to control the flow of liquid. The flowmeter regulates output based on the drone’s speed and altitude, adjusting in real-time to ensure uniform application. This precision control allows for targeted spraying, which reduces waste and maximizes the effectiveness of each treatment.

Spraying nozzles (13) connected to connecting pipes (14), which disperse the liquid in a fine, controlled mist. The nozzles are strategically positioned to achieve broad coverage without compromising the drone’s stability or balance.

This spray mechanism’s accuracy allows the AgROW Quadcopter to provide consistent, even application across crops, reducing the risks of over- or under-application. This optimized application saves resources, minimizes environmental impact, and promotes healthier, more uniform crop growth.

Landing Gear and Impact Absorption
To protect against damage during takeoff and landing, the AgROW Quadcopter is equipped with landing gear (9), constructed from high-strength aluminum alloy, which provides durability and stability. The landing gear includes:

Landing gear mounts (20) that securely attach the landing gear to the frame, providing stability during landings and ensuring the gear remains firmly in place.
Shock-absorbing features integrated within the landing gear, which cushion the impact of landings. This impact absorption protects the frame and other components from structural stress, extending the overall lifespan of the drone.
The landing gear’s durable construction and shock-absorbing properties make it suitable for use on various terrains, reducing wear and tear on the frame and lowering maintenance costs associated with rough landings.

Working of the Invention
The AgROW Quadcopter operates as a coordinated, integrated system where each component plays a critical role in achieving high-performance crop spraying. Its working process can be broken down into several stages:

Pre-Flight Preparation: Before flight, the operator fills the liquid tank with the required treatment solution. Using GPS coordinates, they program the desired flight path and spray coverage area. The battery is securely attached to ensure a consistent power supply throughout the mission.

Takeoff and Navigation: Upon initiation, the drone takes off and stabilizes at a designated altitude. The GPS system guides the drone along its programmed path, while the flight controller adjusts motor output to maintain altitude and direction, compensating for environmental factors like wind.

Spraying Operation: As the drone follows its designated route, the pump activates, and the flowmeter precisely regulates the liquid output. The nozzles release a fine mist, ensuring even distribution of treatment over the target crops. This real-time adjustment to flow rates based on speed and altitude ensures uniform coverage and minimizes resource wastage.

Real-Time Adjustments: If necessary, the operator can make on-the-fly adjustments using the remote control. This includes altering spray patterns, adjusting altitude, or modifying the route to accommodate specific field conditions. The GPS and receiver system enable these adjustments seamlessly.

Landing and Maintenance: After completing its spraying cycle, the drone returns to its starting location and initiates a controlled descent. The shock-absorbing landing gear cushions the landing, protecting the frame and minimizing wear. Following each flight, the battery can be swapped, and the tank refilled, allowing the drone to be prepared for its next mission promptly.

By integrating these components into a single, cohesive system, the AgROW Quadcopter provides precise, efficient, and reliable agricultural spraying. This invention addresses the needs of modern agriculture for high-capacity, low-maintenance drones capable of meeting the demands of large-scale crop management, offering farmers a powerful tool to optimize resource use and improve crop health.
