| 摘 要： | 前期设计的滚筛式自动除杂选果装置，在测试运行过程中发现了3个问题:一是筛网由不锈钢丝网制作，钢丝比较细，在实际处理原料时会损伤果料；二是钢丝筛网的交叉部位窄小，运行中会夹卡杂质，加之部分杂质柔软细长，长时间工作后杂质会在筛网上缠绕，造成除杂效率下降；三是运行中筛网下部用于清除筛网上搭挂杂质的圆筒状夹辊的效果较差。该文针对上述问题，对存在问题的部件进行重新设计，主要对筛网、杂质夹取器和筛网顶部结构做了较大改进。

| Abstract: | Aimed at the original design of automatic removing impurities and sorting fruit device with roller sieve，3 problems in the testing process were found.The first one is that sieve mesh was made by stainless steel wire mesh，and steel wire was thinner.In actual processing，raw materials would damage the fruit.The second one is that part of steel wire sieve mesh cross was narrow，impurities would be clamped in the operation.In addition，other part of impurities were soft and slender，after working for a long times，impurities would be wound on the screen.It would result in decreased efficiency of removing impurity.The last one is that effect of lower part of screen in operation is used to remove cylindrical nip rollers that carry impurities on screen was poor.Aiming at above problems，parts with existing problems were redesigned.The screen，impurity picker and top structure of screen had been greatly improved. |
