摘要

我国鲜食葡萄进口量位居世界前列，而出口量则相对较少，价格远低于世界出口平均价。这一现状部分归因于国内外鲜食葡萄采摘环节机械化程度不足，仍然高度依赖人工或简单机械。针对这一问题，本课题设计了一种葡萄采摘运输一体设备，旨在提高采摘效率，减少果实损伤，并推动葡萄产业的机械化发展。

本课题设计的葡萄采摘运输一体设备，手持杆状剪刀作为采摘工具，手握端采用自行车手捏闸形式进行操控，工作端则设计有路径控制器来控制剪刀的开启与闭合，同时利用弹簧实现剪刀的自动闭合。此外，设备还配备了可折叠的葡萄输送机构，在闲置时可以折叠起来，节省空间。本文详细阐述了设备的总机架机构的结构形式和结构尺寸，动力传动系统的选择与设计，以及主要零部件的结构尺寸和选型。最后，对设备进行了强度校核和三维造型与装配，为鲜食葡萄采摘提供了一种全新的机械化解决方案。

Abstract

China's fresh grape imports are among the top in the world, while the export volume is relatively small, and the price is far lower than the world average export price. This situation is partly attributed to the lack of mechanization of fresh grape picking at home and abroad, which is still highly dependent on artificial or simple machinery. In view of this problem, this project designed an integrated equipment of grape picking and transportation, aiming to improve the picking efficiency, reduce fruit damage, and promote the mechanization development of grape industry.

The grape picking and transportation integrated equipment designed in this project, with rod scissors as a picking tool, the hand end is controlled in the form of bicycle hand pinch brake, the working end is designed with a path controller to control the opening and closing of the scissors, and the spring is used to realize the automatic closure of the scissors. In addition, the device is equipped with a folding grape delivery mechanism that can be folded up when idle to save space. This paper expounds the structural form and structural size of the main frame mechanism of the equipment, the selection and design of the powertrain system, and the structural size and selection of the main components. Finally, the equipment is strength checked and three-dimensional modeling and assembly, which provides a new mechanized solution for fresh grape picking.
