摘要
以进一步提升薯类收获机的综合作业效率为目标,从产品设计最优化角度入手,针对其结构装配及作业控制展开研究.考虑薯类收获机的作业对象特点及设计指标要求,采用机械装配式设计的实现机理,搭建用于薯类收获机装配式设计的精确处理模型,进行核心零部件的设计装配,通过执行过程的控制监测,完成薯类收获机的装配式设计整机呈现.进行挖掘马铃薯的作业试验,结果表明:基于薯类收获机的装配式设计正确可行,整机装配精度可达 97.58%,各项作业指标良好,破损率可降低至 2.78%;当作业速度为 0.8 m/s、振动转速为 90 r/min时,明薯率可达 96.70%,优于薯类收获的设计指标要求,具有较高的适用性与可靠性.
Abstract
With the goal of further improving the comprehensive operation efficiency of potato harvesters,research was conducted on their structural assembly and operation control from the perspective of product design optimization.Consider-ing the characteristics of the operation object and design index requirements of the potato harvester,the implementation mechanism of mechanical assembly design was adopted to build an accurate processing model for the assembly design of the potato harvester,and the design and assembly of core components were carried out.Through the control and monito-ring of the execution process,the assembly design of the potato harvester was completed,and the entire machine was presented for potato excavation experiments.The results showed that the assembly design based on the potato harvester was correct and feasible,and its overall assembly accuracy could reach 97.58%.All operation indicators performed well,and the damage rate during the operation process could be reduced to 2.78%.When the operation speed was 0.8 m/s and the vibration speed was 90 r/min,the bright potato rate could reach 96.70%,which was superior to the design indicators re-quirements for potato harvesting and has high availability and reliability.This design approach would provide practical reference value for researchers to break through the research and innovation of potato harvesting equipment.
