松籽剥壳机结构设计 摘要 此次设计的主要内容，便是从松籽移动，破壳方法，切割结构等方面分析松 籽剥壳器的问题。壳切割不完全和松籽上的高压是影响压碎松籽产量和果仁率的 主要原因。根据松树种子的结构和松壳的特点，提出了点，线，面的三段式低压 壳技术。设计了一种新的多通道去壳器，该过程具有三步式去壳过程，并以松籽 作为低压脱壳行星运动，并讨论了其结构设计，关键结构参数以及动力学参数的 计算。 并且对剥壳器具的一些主要部件的研究计算，首先是对刀具的研究计算，将 其作为松籽剥壳的主要部件；其次是对动力系统的设计，例如对减速器的研究设 计、齿轮、轴、轴承等部件的设计计算及其校核，通过对这些部件的研究设计， 完成此次论文的撰写。 关键词：松籽；剥壳；多通道；尖齿破壳；三步剥壳工艺 I Abstract The main content of this design is to analyze the problems of the pine seed sheller from the aspects of pine seed movement, shell breaking method and cutting structure. Incomplete shell cutting and high pressure on the pine seeds are the main reasons that affect the yield and kernel rate of crushed pine seeds. According to the structure of pine seeds and the characteristics of pine shells, a three-stage low-pressure shell technology of point, line and surface was proposed. A new multi-channel shelling device was designed. This process has a three-step shelling process, using pine seeds as a low-pressure shelling planetary motion, and discussed its structural design, calculation of key structural parameters and dynamic parameters. And the research and calculation of some main parts of the shelling appliance, first of all, the research and calculation of the cutter, which is used as the main part of the pine seed shelling; second, the design of the power system, such as the design and research of the reducer, gear Design calculation and verification of shafts, bearings and other components, through the research and design of these components, completed the writing of this paper. Key words: pine seed; shelling; multi-channel; sharp tooth breaking; three-step shelling process II 目录 第一章 引言1 1.1 选题背景1
