温室雾培蔬菜收获机收获机构的研究设计

Design of Aeroponics Greenhouse Vegetable Harvester Harvesting Machanism

雾培种植具有节约空间、增大产量等特点,是一种新型的种植模式,代表了未来农业种植的方向。为此,针对雾培蔬菜收获劳动强度高、收获效率低等问题,创新性地对温室雾培蔬菜收获机中收获机构进行系统性设计,达到对雾培蔬菜快速稳定收获切根的目的要求。依据人工收获流程及定植板的实际特征,利用Solid Works对蔬菜收获机构进行方案设计,在设计过程中参考了成熟的工程案例,选取合适的切根方法和刀具结构,减少了切削方式及振源振动对收获切根的影响。运用Solid Works Motion对收获机构中的切根机构的运动稳定性进行验证,证明了切根机构在工作过程中可以稳定运行,保持稳定的加速度。利用ANSYS对收获机构中的夹取手爪和切根手爪进行有限元分析,确保关键结构的强度和刚度达到工程技术要求,有效地减少了生产资源的浪费,同时缩短了结构设计的时间,并为样机制作提供了坚实的基础。

Aeroponics planting has the characteristics of space-efficient, high productivity and so on , which is the new cultivation way in the future and represents the future direction of agricultural cultivation .In this paper , a planting aero-ponics greenhouse vegetable harvester which achieve the purpose of rapid and steady harvest aeroponics cut root vegeta -bles requirements is designed innovatively , aiming at the shortage of high labor strength and low harvest efficiency in the traditional harvesters .Through the analysis of manual harvesting process as well as the actual characteristics of vegetables and planting board , the vegetable harvest mechanism is designed by SolidWorks .In the design process , it refer to the mature project cases as well as select the appropriate method and tool cutting root structure , the cutting mode and vibra-tion sources for harvesting root effect has reduced .In addition , the motion stability cut root mechanics in the harvest me-chanics is verified by SolidWorks Motion , it prove the cut root mechanics can keep constant stability acceleration during the cutting process .Eventually , using ANSYS for harvest mechanics gripping paw and cut roots for finite element analy-sis, which can ensure the strength and stiffness of the key structure to achieve engineering and technical requirements , reducing the waste of productive resources effectively , reducing design time and provides a solid foundation for prototyping at the same time .
