摘要

随着农业种植的技术化、机械化，插秧机在农业机械生产中占据重要地位。我国是个人口大国每年对于各种农作物需求量非常大，对于秧苗移栽的效率和质量也需要提高，而我国人口老龄化的问题严峻，劳动力短缺愈发明显，因此本课题旨在设计一款适用于秧苗移栽机械化的插秧机，用于提高生产效率，节省劳动成本。论文围绕此目的，设计了一种插秧机运动的部分结构：分插机构、送秧机构、凸轮机构、动力系统、传动链五个部分，并进行了机械结构设计、装配，使其能实现盘钹分苗、秧苗零速差入土、秧苗深度、行距、株距可调节、苗间距不受车速影响的功能。其中送秧机构选择横向送秧机构中分插机构的设计包括了取秧器，主要有栽植臂和秧爪、驱动机构的设计；送秧机构部分的设计包括了凸轮的设计，并对各结构中的重要零部件的强度进行校核。
