Description

Technical Field

[0001] The utility model relates to the technical field of agricultural apple picking tools, in particular to an automatic telescopic fruit picking device. Background Art

[0002] A fruit picker is a tool specifically designed for picking apples and similar fruits. Its purpose is to improve picking efficiency, reduce labor intensity, and minimize damage to the fruit and the trees. There are several types of fruit pickers: 1. Handheld fruit pickers: These typically consist of a telescopic pole, a head with a gripping mechanism, and a handle. The user holds the handle, extends the head toward the fruit, and by pulling a trigger or lever on the handle, the claws or hooks in the head grasp the fruit. With a simple twist, the picker is removed. These are suitable for home or small orchards and trees with low canopies. 2. Electric fruit pickers: These utilize an electric motor, typically battery-powered. A button or touch switch controls the motor, driving the gripping mechanism to automatically grasp the fruit and rotate it for easy removal. These are ideal for large orchards or those requiring long work hours, reducing the manual burden. 3. Multifunctional fruit pickers: In addition to basic picking functions, they may also integrate pruning, spraying, and other functions. By replacing different head attachments, they can perform a variety of operations. These are suitable for situations requiring comprehensive orchard management, improving work efficiency. 4. Lifting platform fruit picker: This model features a lifting platform or ladder with adjustable height, allowing the user to stand on the platform and reach high-rise fruit. The platform is raised to the desired height, and the user stands on it to pick fruit. This model is suitable for trees with high canopies or large orchards.

[0003] Design features of the fruit picker: 1. Lightweight and durable: It is usually made of lightweight materials (such as aluminum alloy, carbon fiber) to reduce the burden on the user, and it is durable and not easy to damage. 2. Ergonomic design: The handle design conforms to ergonomic principles, is comfortable to hold, and reduces fatigue caused by long-term use. 3. Grasping device: The grabbing device is usually designed with flexible materials or soft pads to avoid damaging the surface of the fruit. 4. Telescopic rod: The design of the telescopic rod allows the tool to adjust the length to adapt to fruit trees of different heights. 5. Safety measures: A locking mechanism is provided to prevent the grabbing device from accidentally loosening during use. By using an apple picker, the efficiency of orchard management can be greatly improved, the intensity of manual labor can be reduced, and it helps to improve the quality and yield of the fruit. Choosing the right type and design of fruit picker is very important for orchard managers.

[0004] Currently, telescopic fruit pickers are primarily designed to be single-section telescopic, meaning a telescopic tube is inserted within a main sleeve. This results in limited control over the length of the main stem, and the device is also inconvenient to carry when retracted. The fruit picking mechanism of these fruit pickers typically utilizes a scissor-like structure, with a switch or motor on the handle controlling the movement of the scissors to cut the fruit stems. However, the scissor blades cannot be clearly aligned with the fruit stems, causing fatigue after prolonged handling and low fruit picking efficiency. Therefore, there is an urgent need to design an automatic telescopic fruit picker to address the inconvenience of carrying existing fruit pickers and the low fruit picking efficiency caused by large errors in scissor blade alignment.
