摘要
小型莴笋收获机，莴笋三个部分，第一部分是什么的新鲜的叶子，第二部分是中间的老黄叶子，第三部分是它的根在本次的设计中，主要对莴笋生长的特性以及收割工艺的特点进行了分析，对其工作过程进行了比较分析，对整体结构进行了设计，对主要工作部件进行了选择，对轴，轴承等部件进行了设计校核。对标准件，紧固件进行了选择设计，最终设计出了一款小型莴笋收获机。同时还对其三维进行了绘制。因为设备的机械系统的结构简单，以及设备的造价成本相对的低，所以这种小型莴笋收获机适应了小规模的农场式莴笋种植收获的农业生产方式，其作业质量也和以往的人工收获方法相比有了明显的提高。

Abstract
Small lettuce harvester, lettuce three parts, the first part is what fresh leaves, the second part is the middle of the yellow leaves, the third part is the root, In this design, the main characteristics of lettuce growth and the characteristics of the harvest process were analyzed, the working process was compared and analyzed, the overall structure was designed, the main working parts were selected, the shaft, bearing and other parts were designed and checked. The standard parts, fasteners were selected and designed, and finally designed a small lettuce harvester. It is also plotted in three dimensions. Because of the simple structure of the mechanical system of the equipment, and the cost of the equipment is relatively low, so this small lettuce harvester is adapted to the small-scale farm lettuce planting and harvest agricultural production mode, and its operation quality is also significantly improved compared with the previous artificial harvest methods.
Key words: lettuce, harvester, complete separation;

1.1莴笋介绍
莴笋（学名：Lactuca sativavar.angustata）又称莴苣，菊科莴苣属莴苣种能形成肉质嫩茎的变种，一二年生草本植物。别名茎用莴苣、莴苣笋、青笋、莴菜。产期：1-4月。莴苣原产地在地中海沿岸，大约在五世纪传入中国。[1]地上茎可供食用，茎皮白绿色，茎肉质脆嫩，幼嫩茎翠绿，成熟后转变白绿色。主要
