“基于单一果枝振动的果实采收装置设计”文献综述
摘 要
大型机械的林果采收过程中会造成很高的损坏率，高的果实损坏率不适用鲜果市场和小型林果采收。因此需要设计小型林果采收机械，以适应局部林果采收需要。对此本文分析了适用于激振单一果枝的小型激振采收装置和隔振减振装置的可行性和技术机理，同时阐述了国内外目前对相关领域的研究现状和最新进展。分析所搜集的相关研究专利，接下来通过机构创新组合与模块化设计对所需要研究的基于单一果枝振动的果实采收装置进行设计；并采用软件分析等方式，对激振采收系统进行振动特性优化，实现理想的隔振减振效果。

Literature Review of 'Design of Fruit Harvesting Device Based on Single Fruit Branch Vibration'
ABSTRACT
Large machinery will cause a high damage rate during the fruit harvesting process. High fruit damage rate is not suitable for fresh fruit market and small forest fruit harvesting. Therefore, it is necessary to design a small forest fruit harvesting machine to meet local forest fruit harvesting needs. In this paper, the feasibility and technical mechanism of a small-scale excitation and recovery device and a vibration isolation and damping device suitable for exciting a single fruit branch are analyzed. At the same time, the current research status and latest progress in related fields at home and abroad are described. Analyze the related research patents collected, and then design the fruit harvesting device based on the single fruit branch vibration that needs to be researched through the innovative combination and modular design of the mechanism; and use software analysis to vibrate the vibration harvesting system The characteristics are optimized to achieve the ideal vibration isolation and damping effect.

- 前言
我国是世界第一大水果生产国，也是世界第一大水果消费国，在我国，水果产业是种植业中仅次于粮食和蔬菜的第三大产业，在国民经济中占有非常重要的地位。[[1]]林果收获是整个林果生产全过程中最重要的部分，具有季节性强、采摘周期短劳动强度大等特点，所用劳动力占整个生产过程所用劳动力的35%~45%[[2]]。目前我国林果采摘和分选主要以人工作业为主[[3]]，随着劳动力成本的快速增长，这部分费用在整个林果生产过程中的占比也随之增长。随着林果产业规模的不断扩大，急需一些机械化、半机械化的采摘设备来替代人工采摘，以提高劳动生产率，降低生产成本。其中小型林果的采收一直是个难题，目前国内外多采用振动式、气力式、剪切式、梳刷式、采摘机器人等方法进行采收。利用采收机械能够快速、有效地完成对果实的采收，可促进果品的大面积、规模化生产，满足农业现代化的要求，果实采收机械具有广阔的市场前景。
