Structural design and finite element analysis of spinach seeding and harvesting machine
摘要
Abstract
In response to the existing problems of spinach harvesters leaving roots,uneven root cutting depths,and the low sowing efficiency of broadcast seeders,as well as the high cost of line seeders,we innovatively designed a spinach seeding and harvesting machine that can adjust plowing depth,harvest whole plants,and sow seeds at a fixed distance through theo-retical calculations and SolidWorks modeling,and built a smart fish model.We used the Simulation module for finite element analysis of the frame,and the results show that the maximum stress points of the machine are mainly located at the feed port at the front end of the frame.Therefore,during manufacturing,we need to enhance the welding strength at this location.Ad-ditionally,to reduce damage to the main working part-the plow-in greenhouses and corrosive soil environments,we use fiber-glass with excellent corrosion resistance instead of gray cast iron.The comprehensive comparison and finite element analysis results indicate that the strength and hardness of the fiberglass material are appropriate.If properly designed for molding,fi-berglass can achieve better long-term cost-effectiveness and is expected to become the preferred material for plow manufac-turing in future agricultural machinery.In summary,this paper can provide some theoretical references for enterprises in the future design of spinach seeding and harvesting machines and the optimization of key components.关键词
