牧草联合收割作业已经非常普及，但收割过后牧草散落草地，导致因季节性牧草过剩而得不到合理利用被废弃,不仅浪费了牧草资源,造成经济损失,同时也污染了草地和环境，人工收集则费时费力。使用牧草打捆机可将农作物收割过后的牧草直接打成捆进行收集，方便人们运输和储存，减轻农民体力劳动。本文总结已有打捆机的成熟经验，吸收国外打捆机的先进技术，设计符合生产需求的牧草打捆机，对机器的设计原理和工作过程进行分析，对相关参数进行论证设计。本文在前人研究的基础上，运用现代设计方法进行了这方面的探讨。

ABSTRACT
In China, grass combined harvesting work has been very popular, but after the harvest grass scattered grassland, cause because of seasonal forage surplus and not to the rational use of the abandoned, not only a waste of forage resources, resulting in economic losses, at the same time the grassland and environmental pollution, artificial collection is time-consuming and laborious. The use of forage harvester can be harvested after the harvest of crops directly into a bundle of hay to collect, facilitate the people to transport and storage, reduce the physical labor of farmers. This paper summarizes the existing baler mature experience, absorb foreign advanced technology of baler, designed to meet the demand for the production of forage baling machine and the design principle and working process of machine are analyzed and the relevant parameters for design verification. On the basis of previous studies, this paper discusses the use of modern design methods in this area.
Keywords: Bundling machine, related parameters, design principle, working process
