甘蔗机械收获除杂技术研究现状与前景展望OA

In recent years,China's sugarcane mechanical harvesting technology has been significantly applied and developed,and has gradually formed a sugarcane mechanical harvesting model suitable for China.However,the development of sugarcane mechanical harvesting impurity removal technology is slow,and the existing sugarcane impurity removal technology has not effectively reduced the impurity rate of sugarcane mechanical harvesting,which seriously restricts the whole mechanization process of sugarcane industry.On the basis of summarizing the application of sugarcane mechanized harvesting in Guangxi and Yunnan provinces,the research and development status of sugarcane mechanical harvesting,leaf stripping and impurity removal technology,air separation and impurity removal technology and pretreatment and impurity removal technology before pressing were analyzed.From the aspects of life,impurity removal efficiency,energy consumption and impurity removal performance of leaf stripping components,this paper mainly introduces the problems of sugarcane leaf stripping and impurity removal,air separation impurity removal and pretreatment impurity removal technology before pressing,such as easy fatigue failure of leaf stripping components,mismatch of harvesting speed and feeding speed with impurity removal speed,resulting in idle rotation of equipment,poor passing ability of curved sugarcane,and difficulty in effective screening of impurities in sugarcane pocket and sugarcane section.The measures and suggestions for selecting suitable sugarcane harvesting machinery,accelerating the development process of machinery and equipment,and adopting wear-resistant materials for leaf stripping components are put forward.At the same time,it is also pointed out that the impurity removal technology of sugarcane mechanical harvesting in China will develop in the direction of vibration-wind separation combined innovative impurity removal technology,optimization of cutting disc design,intelligent automatic parameter adjustment of impurity removal device and green environmental protection of impurity removal power in the future.
