为解决南疆矮化密植枣园红枣收获难题,针对矮化密植种植模式下的枣园特点,设计出基于清扫方式和气吸方式相结合的新型落地红枣收获机.介绍了整机结构和工作原理,并对关键部件进行了设计,确定了各关键部件的基本结构和具体型号.同时,分析了红枣清扫聚拢过程,得出清扫辊刷转速、机具前进速度与清扫辊刷清扫效果之间的关系,并通过田间试验验证了清扫辊刷转速、机具前进速度与清扫辊刷清扫效果之间的关系.该机整体尺寸小,适应性强,作业效率高,适用于南疆矮化密植种植模式的枣园进行红枣收获作业.

英文摘要：

In order to solve jujubes harvesting problem of dwarf and dense planting jujube in South Xinjiang.According to the characteristics of dwarf and dense planting jujube orchard, a new type landing-jujube harvest machine that combined the pattern of cleaning and vacuum was designed and finally the structure parameters and specific type were determined.The whole structure and working mechanism of the machine were introduced, the key operation components of the machine were designed.The processes of jujubes cleaning gather were analyzed and the relationships between roller-brush rotating speed, forward speed of machines and cleaning effect of roller-brush were achieved.And the relationships were tested and verified by field experiments.The machine has advantages of small overall dimension, good adaptability, high operation efficiency and can be used to harvest landing-jujube of dwarf and dense planting jujube orchard in south Xinjiang.
