摘　　要：针对现有马铃薯种薯切块机易切除顶芽的问题,采用夹持马铃薯种薯的方式进行切块,设计一种能有效保留种薯顶端优势的夹持装置,主要包括夹持爪、托板和弹簧座等结构。以喂入高度、弹簧劲度系数和夹板材料为试验因素,以漏取率、损耗率为评价指标,进行三因素三水平正交试验,对试验结果进行极差分析,确定最优参数组合。验证试验结果表明,喂入高度为100 mm,弹簧劲度系数为60 N/m,夹板材料为EVA时,漏取率为2.68%,损耗率为4.43%,在该参数组合下马铃薯种薯夹持装置漏取率和损耗率均较低,满足马铃薯切种要求。Aiming at the problem that the existing seed potato cutting machine often cuts the top bud of the potato,a clamping method of seed potato was adopted to cut the potato,and a clamping device was designed to effectively retain the top advantage of seed potato.The device includes clamping claws,supporting plates,and a spring seat.A three-factor and three-level orthogonal test was conducted,with feeding height,spring stiffness coefficient,and splint material as test factors and empty bowl rate and loss rate as evaluation indicators.The test results were analyzed by range,and the optimal parameter combination was determined.The verification test results showed that when the feeding height was 100 mm,the spring stiffness coefficient was 60 N/m,and the splint material was EVA,the empty bowl rate was 2.68%,and the loss rate was 4.43%.Under this parameter combination,the miss rate and loss rate were both low,meeting the potato cutting requirements.
