Design and Experimentation of Conveying and Separating Device for Fresh-eating Sweet Potato Harvester in Sandy Soil
摘要
Abstract
Aiming at the problems of mechanization harvesting high skin breaking rate of fresh-eating sweet potato under sandy soil,this study designed a rubber-wrapped integrated conveying and separating device.The device key components were designed,the quadratic regression orthogonal rotating combination design was adopted to conduct field tests and performance analysis with the line speed of the conveying and separating device,the amplitude of the jitter device,and the digging depth as test factors,and the sweet potato skin breaking rate and loss rate as the evaluation indexes,as well as the variance analysis response surface drawing and parameter optimization were carried out by using Design Expert software of the test results.Optimal working parameter combination after optimization:the line speed of the conveying and separating device was 0.28 m·s-1,the amplitude of the shaking device was 14 mm,the digging depth was 232 mm,forecast the skin breaking rate was 0.851%,the loss rate was 0.678%.According to the verification test get the parameter combination below the skin breaking rate was 0.866%and the loss rate was 0.694%,and the optimization results were basically consistent with the verification results,which met the requirements of fresh-eating sweet potato harvesting in sandy land.关键词
