    摘要:

    設(shè)計了一種適用于油菜精量排種的槽孔輪式排種器,分析了該排種器的結(jié)構(gòu)特征及其工作原理,提出了清種輪軸實現(xiàn)清種、護種帶護種和鋼絲推種的排種機構(gòu),確定了該排種器的主要結(jié)構(gòu)和性能參數(shù)。試驗表明,在清種輪軸轉(zhuǎn)速為104r/min、型孔直徑2.8mm、推種鋼絲傾角33°時,破碎率最低為0.73%。

    Abstract:

    A slot wheeled precision metering device for rapeseeds was designed. The structure and working principle were studied. The metering mechanism mainly consisted of a seed-cleaning wheel axle, a seed-retaining belt and a weed pushing ringed wire-steel. By experiments, the key structure and performance parameters were analyzed and determined, the lowest seed damage index was obtained when the speed of seedcleaning wheel axle was 104r/min, the diameter of shaped hole was 2.8mm and the inclined angle of wire steel was 33°
