设计简介
摘要
烟根挖掘机，又可以称作是拔杆机。就是用拔杆装置将烟草、棉花等作物采摘完的根茎自动连根拔起。一些秸秆矮小的农作物在田间耕作的时候直接打碎埋入土里，但是像烟草，棉花等作物的根茎比较粗长的不易这样处理，因此就需要连根拔起再进行二次处理。烟根挖掘机是将作物根茎拔起后便于转移或者直接将根茎在田里处理粉碎，节省劳动力，大大减轻了农民朋友的劳动强度，便于农民进行土壤改良和翻耕，同时也便于充分利用植物根茎资源，一定程度上减少了根茎燃烧带来的环境污染，有利于保护大气环境，发展生态农业，便于实现有机农业和可持续发展农业。本次设计主要是针对挖掘机的挖掘切割部分和传动系统的分析设计。

Abstract
tobacco root excavator, pulling rod can be described as machine. Is to use pull rod device will be picking the roots of tobacco, cotton and other crops automatically by the roots. Some short straw of crops in the field farming directly break buried in the grave, but like tobacco, cotton and other crops root fairly thick long difficult this kind of treatment, so they need to be uprooted and secondary processing. Smoke root excavator is transferring crop roots pull up later processing crushing in the fields or directly to the roots, the save Labour, and greatly reduce the labor intensity of farmers friends, facilitate the farmers for soil improvement and ploughing, also easy to make full use of plant root resources, to a certain extent reduced the rhizome combustion pollution to the environment, is conducive to protect the atmospheric environment, the development of ecological agriculture, to realize organic agriculture and agricultural sustainable development. This design mainly for excavator digging cutting part and the analysis of the transmission system design.
Keywords: smoke root excavator, transmission system; Cutting excavation section.
