Abstract：Aiming atthe problems of mechanization harvesting high skinbreakingrateoffresh-eating swet potato undersandysoil，this studydesignedarubber-wrapped integrated conveyingand separating device.The device key components were designed，the quadratic regresson orthogonal rotating combination design was adopted to conduct field testsand performanceanalysiswith the linespeedof theconveyingandseparatingdevice，theamplitudeof the jiter device，and the digging depthas test factors，and theswe potato skin breaking rate and lossrate as the evaluation indexes，as wellas thevariance analysis response surface drawingand parameter optimization were caried out by using Design Expert softwareof the test results.Optimal working parameter combination after optimization：the line speed of the conveying and separating device was 0.28m*s-1 ，the amplitude of the shaking device was14 mm，the digging depth was 232 mm，forecast the skin breaking rate was 0.851% ，the loss rate was （204号 0.678% . According to the verification test get the parameter combination below the skin breaking rate was 0.866% （2 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.
