新疆是世界三大葡萄天堂种植区之一，是我国主要的酿酒葡萄种植区，但其采收完全依靠人工，已严重制约了酿酒葡萄产业发展，机械化采收是必然趋势。国外普遍采用的振动击打采收方法，不适于新疆多主蔓扇形树形、长宽叶幕形种植特点的酿酒葡萄机械化采收。本项目针对新疆酿酒葡萄的种植特点，提出振摇式采收方法，拟从获取由振动源、葡萄枝蔓与果穗组成的振动系统的振动传递规律入手，研究葡萄果实与果蒂间的连接力，研究不同果穗性状条件下葡萄粒受到振动时的运动形式及受力情况，揭示振摇式采收方法下葡萄的果-蒂分离机理；研究基于弹性连接双摇杆平面四杆机构的振摇分离机构，建立其运动学和动力学理论方程，并进行虚拟仿真分析，试制物理样机，开展试验研究，确定果实成熟度、振幅、频率、分离时间等因素对分离性能影响的主次关系，寻求最优参数组合，探究振摇分离机构采收机理。研究成果将为适应新疆酿酒葡萄种植特点的收获机研发奠定理论与技术。

Xinjiang is one of the world's three major grape paradise planted area, and it's the major wine grape area in China, but the harvest is mainly rely on manual, which serious restrict the further development of the grape industry, mechanized harvesting is inevitable trend. Shaking methods widely used abroad, however, the method is not suitable for Xinjiang wine grape of multiple main vine fan-shaped tree, length-width canopy shape characteristics mechanized harvesting. This project is intended for planting characteristics of Xinjiang wine grapes, shaking method is put forward, starting from the vibration source, grape tendrils and clusters of vibration transfer rule of vibration system, research the connection force of fruit and pedicel, and grape grain vibration form of exercise and stress distribution under the conditions of different state character. According to these, reveal the principle of vibration and struck grape fruit-pedicel separation mechanism; Research the shaking separation device based on the elastic connection dual rocker flat four agencies, establish its theory of kinematics and dynamics equations and make a virtual simulation Analysis; make physical prototypes, conduct experimental studies , determine factors ,which are fruit maturity, amplitude, frequency, separation time etc., primary and secondary relationships on separation performance; Find the optimal parameter combination, explore the harvesting mechanism of shaking separation device. The research will lay the theoretical and technical basis for Localization of grape harvesting machine which is to adapt to the characteristics of the wine grape growing in Xinjiang.
