丘陵山区甘薯收获机设计方案的改进

Improvement of design scheme of sweet potato harvester in hilly area

为解决丘陵山区甘薯机械收获动力消耗大、薯土分离不清、埋薯等问题,设计一种丘陵山区甘薯收获机样机,文章总结样机在田间作业试验情况并对出现的问题进行分析,提出改进方案。按照改进方案试制的样机经初步田间试验,对比原先的设计方案有一定的改进效果。

In order to solve the problems such as large power consumption,unclear separation of sweet potato and soil,and bur⁃ied potatoes,a sweet potato harvester prototype was designed in hilly and mountainous areas.The paper summarized the field experi⁃ment of the prototype,analyzed the problems,and put forward the improvement plan.The prototype produced according to the im⁃proved scheme is tested in the field,it has a certain improvement effect compared with the original design scheme.
