1、毕业设计中文摘要秸秆打捆机的设计摘要我国自古以来就是农业大国,拥有广袤的土地,人民在从事农业生产活动中不仅获得了粮食,还获得了很多的秸秆资源。秸秆作为可再生资源,在我国大部分地区都没有得到重视,其使用情况更是不容乐观,大部分地区的做法是将秸秆在田地里直接粉碎还田,有些地区甚至将秸秆就地焚烧,不仅会影响气候环境使全球变暖,甚至有的时候会引发山林大火,危机人民的生命安全,也造成了资源浪费。而秸秆作为资源使用的前提是要能够易于收集、运输。为此需要设计一款符合中国实际情况的秸秆打捆机。为此本文是针对现有的YY5080型秸秆打捆机进行改进设计。本文开头先分析了我国目前秸秆资源的利用情况及打捆机的发展趋势
2、,研究的背景和意义;对国内外秸秆打捆机的发展状况进行了简要介绍。设计的主要内容包括对秸秆打捆机的捡拾装置进行改进,加宽了捡拾机构的作业幅度及在原有弹齿的基础上增加了软弹齿,田地里的秸秆被清理的更加干净,提高了捡拾效率。改善了喂入装置,增强了喂入装置的推送能力。针对上述改进对打捆机的整机结构进行了调整。对打捆机的传动系统进行计算及校核。并运用CAD软件进行辅助设计。该机采用拖拉机后悬挂的方式进行牵引,结构简单,体积也相对较小,性能良好,容易操作,适合我国这种小农经济社会。关键词:圆捆机;捡拾机构;喂入机构;牵引式毕业设计英文摘要Design of Straw Bale MachineAbstra
3、ctChina has been an agricultural country since ancient times, with a vast land, peopleengaged in agricultural production activities not only obtained food, but also obtained alot of straw resources. Straw as a renewable resource in our country, most areas have notbeen ignored, its usage is not optim
4、istic, most of the region, it is straw returning directlycrushing in the fields, some areas even burned straw in situ, that global warming will notonly affect climate environment, sometimes even cause wildfires, crisis of peoples lifesafety, It is also a waste of resources- The premise of using stra
5、w as a resource is to beeasy to collect and transport. Therefore, we need to design a straw baler suitable forChinas national conditions. Therefore, this paper is aimed at the existing YY5080 strawbaler to improve the design.At the beginning of this paper, the utilization of straw resources in China
6、 and thedevelopment trend of baling machine are analyzed, and the background and significanceof the research are also analyzed. The development of straw baler at home and abroad isbriefly introduced. The main content of the design includes improving the picking deviceof the straw baler, broadening t
7、he scope of the picking mechanism and adding softpicking teeth on the basis of the original picking teeth, so that the straw in the field iscleaned more cleanly and the picking efficiency is improved. The feeding device is addedto enhance the feeding capacity of the baler. In view of the above impro
