TECHNICAL FIELD
[001] The technical field of the invention pertains to agricultural machinery and automation, specifically focused on harvesting technologies for tree crops. It involves the development of a novel walnut tree shaking device that employs advanced vibration control systems and adaptive sensors to optimize the harvesting process. The invention integrates real-time monitoring of tree health and walnut ripeness to enhance efficiency, reduce labor costs, and minimize damage to trees during the harvesting operation. This technology aims to improve the sustainability and productivity of walnut orchards.
BACKGROUND
[002] Traditional walnut harvesting methods have long relied on manual labor or uniform mechanical shaking systems. These approaches often lead to inconsistent results, where some trees are over-shaken, causing damage to branches and trunks, while others are under-shaken, leaving ripe walnuts still attached. This inefficiency can increase labor costs as multiple passes may be required to collect remaining nuts, ultimately lowering overall yields and increasing the risk of crop loss.
[003] Existing mechanical tree shakers typically apply a fixed vibration intensity, failing to account for individual tree characteristics such as size, age, and health. This one-size-fits-all approach often results in significant tree damage, reducing their productivity over time. The need for a solution that adapts to the specific needs of each tree is crucial for maintaining the health of orchards and maximizing harvest efficiency.
[004] US20090085364A1, which discusses a lightened vibrating clamp for machines harvesting fruit by shaking. While it introduces a composite material for the clamp's exterior, it does not specify how these materials can improve the durability and performance of the harvesting process under continuous vibration, highlighting a gap in the application of advanced materials in tree shaking technologies.
[005] US6658834B1, describes an automated tree sensing and shaking control system utilizing ultrasonic sensors to detect tree distance. However, this system's reliance on a single type of sensor limits its ability to provide comprehensive data on tree health and structural integrity, which are critical for preventing damage during harvesting operations. The lack of adaptability to different tree types and conditions represents a significant limitation of existing technologies.
[006] The increasing prevalence of labor shortages in agriculture, particularly during peak harvest seasons, further underscores the necessity for automated harvesting solutions. Farmers are facing challenges in finding and retaining skilled laborers, leading to delays in harvest and potential crop loss. An autonomous walnut tree shaking device would not only alleviate labor demands but also enhance operational efficiency during critical harvest periods.
[007] Additionally, conventional harvesting methods often result in mixed-quality harvests that require extensive post-harvest sorting. This process can be labor-intensive and time-consuming, reducing the overall quality of the product and increasing waste. By incorporating advanced sensing technologies, a new device could ensure that only ripe walnuts are collected, thus minimizing the need for post-harvest processing and improving overall market value.
[008] The environmental impact of traditional harvesting machinery, which typically consumes large amounts of fuel and energy, has become a growing concern in sustainable agriculture. The development of energy-efficient solutions, such as solar-powered harvesting systems, aligns with modern environmental standards and addresses the pressing need for sustainable practices in agricultural operations
[009] The proposed invention aims to fill the gaps identified in existing technologies by combining multiple sensor types, including LiDAR and infrared, for a comprehensive assessment of tree characteristics. By implementing an adaptive vibration control system that responds to real-time data, the invention promises to revolutionize walnut harvesting, enhancing efficiency, protecting tree health, and ensuring high-quality yields in a more sustainable manner.
SUMMARY
[010] The invention presents a novel walnut tree shaking device that utilizes adaptive vibration control technology to enhance the efficiency and sustainability of walnut harvesting. This automated system autonomously navigates through orchards, assessing each tree's size, age, and health using advanced sensors, which allows it to apply precisely calibrated shaking forces that minimize damage while optimizing nut dislodging.
[011] Equipped with a flexible clamping mechanism, the device gently grips the tree trunk without harming the bark, ensuring secure attachment during the shaking process. The vibration-controlled shaking arm produces adjustable vibrations that are directed both vertically and horizontally, maximizing the harvest of ripe walnuts while safeguarding the tree's structural integrity.
[012] Real-time monitoring is a key feature of this invention, with an integrated health monitoring system that continuously assesses tree stress and overheating. If any potential damage is detected, the system can automatically adjust the shaking intensity or halt the process, promoting long-term tree health and productivity.
[013] Additionally, the device employs a selective harvesting algorithm powered by computer vision technology to identify ripe walnuts, significantly reducing the number of unripe nuts collected. This targeted approach minimizes post-harvest sorting, streamlining the harvesting process and improving overall quality.
[014] The energy-efficient design incorporates solar panels to power the system, reducing reliance on external energy sources and aligning with sustainable agricultural practices. By addressing labor shortages and enhancing the quality and efficiency of walnut harvesting, this invention offers a comprehensive solution to the challenges faced by modern walnut orchards.

[020] The invention consists of an autonomous walnut tree shaking device designed to optimize the harvesting process through adaptive vibration control. This system is mounted on a self-propelled platform that navigates through orchards using GPS technology or pre-programmed routes, ensuring efficient access to each walnut tree without human intervention.
[021] A flexible clamping mechanism is a critical feature of the device, allowing it to securely grip tree trunks of varying diameters while minimizing damage to the bark. The clamp is constructed from soft, padded materials to prevent injury to the tree and is equipped with adjustable pressure settings to ensure a secure yet gentle hold.
[022] The shaking mechanism includes an electric motor connected to a vibration generator that produces adjustable vibrational forces. The intensity and frequency of the shaking can be dynamically modified based on real-time data collected from various sensors, allowing the system to tailor the shaking process to the specific characteristics of each tree.
[023] In one embodiment it is provided that, An adaptive vibration control system is central to the invention, integrating multiple sensors that measure tree trunk diameter, height, and health status. This data is processed by an onboard microprocessor, which calculates the optimal shaking force and duration for each individual tree, enhancing the efficiency of the harvest while reducing the risk of damage.

Throughout this process, real-time data from the health monitoring system continuously informs adjustments to ensure optimal shaking without causing damage.
[028] Following the dislodgment of walnuts, the device releases the tree and records data on tree health and yield, which can be stored for future analysis. This data-driven approach allows orchard managers to make informed decisions regarding tree maintenance and future harvests, optimizing overall orchard productivity.
[029] In one embodiment it is provided, that One of the primary advantages of this invention is its ability to significantly reduce labor costs associated with walnut harvesting. By automating the process, it addresses labor shortages and enhances operational efficiency, allowing for quicker and more effective harvests during critical periods.
