摘　　要：为探明荞麦剥壳机工作过程中对剥壳效果影响的主要参数,选取砂盘转速、剥壳间隙、工作面宽度及砂盘粒度为影响因素,分析以上4种因素对剥壳机极限流量的影响,以及砂盘转速对剥壳效果的影响。结果表明,砂盘转速对出米率和相对碎米率影响明显,砂盘转速高于950 r/min时,相对碎米率急剧上升,但对极限流量的影响缓慢;剥壳间隙在5~7 mm时极限流量随剥壳间隙呈线性增加趋势;工作面宽度的变化会导致极限流量呈直线下降趋势;砂盘粒度对极限流量的影响较小。因此,在保证剥壳效果的前提下,优化剥壳间隙及工作面宽度对极限流量的影响具有潜在价值。In order to find out the main influencing parameters of buckwheat huller on the hulling effect in the working process,rotational speed of sand disc,hulling gap,width of working face and size of sand disc were selected as the influence factors,and effects of the above 4 factors on the limited flow and the effects of rotational speed of sand disc on the hulling effect were analyzed.The results showed that,the rotation speed of sand disc had a significant effect on the rice yield rate and relative rice breaking rate.When the rotating speed of sand disc was higher than 950 r/min,the relative broken rice rate rose sharply,but the effect on the limited flow was slow.In the range of 5 to 7 mm of hulling gap,the limited flow increased linearly with the hulling gap.The width of working face would lead to decline of the limited flow linearly.The size of sand disc had little impact on the limited flow.So for ensuring the hulling effect,it has potential value to optimize the influence of hulling gap and working face width on the limited flow.
