| 摘 要： | 为提高核桃采收效率、降低果树损伤,针对新疆核桃种植模式,设计了树冠振动式核桃采收装置。该装置通过拨杆圆盘的直线往复运动产生的激振力实现核桃振动采收。通过对曲柄滑块总成进行运动分析,推导出了滑块速度和加速度的表达式,并对装置产生的激振力进行求解,得出振动频率为2Hz时装置对核桃最大激振力为134N,验证了该装置进行采收作业的可行性。同时,对采收装置进行惯性力分析,推导出了不同组数曲柄滑块总成的合力表达式,得出了该装置所受惯性力最大为8.69N,为新疆核桃收获机的进一步研究提供了理论基础。

| Abstract: | In order to improve the harvesting efficiency of walnut and reduce the damage of walnut tree , a kind of canopy shaker device was designed under the planting of Xinjiang walnut .The exciting force caused by the straight reciprocating motion of disks with driving levers around was used to harvest walnut .Through the analysis of the slider-crank mecha-nism, the expression of acceleration and velocity were deducted .And the maximum exciting force was solved as 134N by solving mechanism, while the frequency was 2Hz.The feasibility of the mechanism was verified .Meanwhile, the inertia force of mechanism was analyzed to deduct the resultant force expression of different groups slider -crank , and its maxi-mum value was 8.96N.It provides a theoretical basis for the research of Xinjiang walnut harvester . |
