摘 要
近年來,隨著農(nóng)業(yè)科技的發(fā)展和人民生活水平的提高,國內(nèi)外水果品種越來越多,人們對水果品質(zhì)有了更高的要求。為了提高水果種類分選的質(zhì)量和出品的種類,需要進(jìn)行對水果的分選。本文分析了研究和發(fā)展國內(nèi)外的中國水果分選機,展望未來,我們設(shè)計了一種新的水果杯水果分選機構(gòu)類型,該水果分選機果杯是由一個果杯,和僅盛放水果的果盤不同,它由一個步進(jìn)電機以及一個步進(jìn)電機驅(qū)動器和果杯構(gòu)成。采用的是步進(jìn)電機提供動力,由單片機檢測信號并發(fā)送給步進(jìn)電機驅(qū)動器來控制步進(jìn)電機的運轉(zhuǎn),從而達(dá)到分選水果的目的。其機構(gòu)簡單,操作方便,易于維護,提高生產(chǎn)效率,降低勞動強度,降低生產(chǎn)成本,加快果實機械化的步伐,為大型水果實現(xiàn)現(xiàn)代化的前提
