多功能智能联合式大葱收获机设计

Design of Multi-Functional Intelligent Combined Scallion Harvester

【目的】传统大葱收获方式是人工挖掘,劳动量大且效率低,收获质量不能保证,难以满足大葱收获需求,市场迫切需要可代替人力劳动、适合大规模自动化收获的大葱收获机。结合国内大葱种植的农艺要求和种植模式,本研究提出研发设计了一款多功能智能化联合式大葱收获机。【方法】该收获机主要由拨土松土机构、导向结构、合页单向防倒结构、切平捋顺机构、柔性夹持机构、定量翻转机构、滚土机构、抖土收集装置等组成,并通过遥控器控制机器运行,实现收获智能化一体化。【结果】通过实践检验证明,该收获机具有结构紧凑,稳定性强,大葱损伤率低,收集效率高等优点。【结论】该收获机可以提高大葱的收获质量和收获效率,显著降低大葱收获人工成本,促进大葱收获机械化发展,具有重要的现实意义和广阔的推广前景。

[Purposes]The traditional scallion harvesting method is manual mining,which costs a large amount of labor and has low efficiency.Therefore,the quality of harvesting can not be guaranteed,and it is difficult to meet the demand of scallion harvesting.The market urgently needs a scallion harvester that can replace human labor and is suitable for large-scale automatic harvesting.Combined with the agro-nomic requirements and planting mode of scallion planting,this study proposed to develop and design a multi-functional intelligent combined scallion harvester.[Methods]The harvester is mainly composed of soil shifting mechanism,guiding structure,hinge one-way anti-toppling structure,cutting and smoothing mechanism,flexible clamping mechanism,quantitative turning mechanism,rolling mechanism,shaking soil collection device,etc.,and the machine is controlled by remote control to realize intelligent harvest integration.[Findings]The harvester is proved to have the advantages of compact structure,strong insti-tutional stability,low scallion damage rate and high collection efficiency through practical test.[Conclu-sions]The harvesting can improve the harvesting quality and harvesting efficiency of scallion,signifi-cantly reduce the labour cost of scallion harvesting,and promote the development of scallion harvesting mechanization,which has important practical significance and broad promotion prospects.
