摘　　要：为解决现有红枣去核机普遍存在的缺陷,如机构复杂、定位不准确、适应能力低及枣核残留比例高等问题。在对现有红枣去核机机构和结构综合分析的基础上,该文提出了一种新型的红枣去核机机构,给出了排队、上料等机构,对主传动系统和关键执行机构的参数进行了计算。最后制作了样机并进行了试验,结果表明本机器能适应直径在10～24mm范围的红枣,具有不用预先分拣,适应性强,枣核残留比例小于2%等优点。In order to eliminate the defects such as complex mechanism,inaccurate locating,low adaptability and high kernel residue proportion and etc in the existing jujube kernel removing machines,based on the comprehensive analysis of the existing machines and mechanisms,a novel mechanism for jujube kernel removing was proposed in this paper,the feeding mechanism and locating mechanism were designed.Also the key parameters of the main transmission and the executive mechanisms were presented and calculated.Finally,the prototype was manufactured and the experiments were carried out.The results indicated that this machine was suitable for jujube with diameter in the range of 10-24 mm,which had advantages of no sorting,good adaptability and low proportion of kernel residual（less than 2%）.
