摘  要：
针对小粒种子尺寸小、质量轻、形状不规则等特点导致精密播种稳定性差及精度低的问题,在国内外相关研究的基础上,根据该类作物的种植模式和农艺要求,设计了一种适用于小粒种子精密播种的种子带编织机。该装备可以连续实现种子带的自动进给、小粒种子在种子带的精密排种、种子带的编织及将编织好的种绳缠绕成辊等功能。通过理论分析,确定了排种器等关键部件的结构参数,并利用单因素试验和正交试验研究分析了排种辊筒转速、种子带进给速度和气室负压对排种性能的影响。试验结果表明:当排种辊筒转速为8~12r/min、对应纸带前进速度为0.08~0.12m/s及气室负压为2~2.5k Pa时,机器排种性能指标获得最佳值。

摘  要：
To resolve the poor precision seeding quality of the small plant seeds caused by their lightly weight,small size and irregular shapes,according to the agricultural requirement of these plants,a seed tape knitting machine which used to precision seeding of small plant seeds was designed based on the researches from domestic and overseas. The functions that seed belt feeding automatically,precision seeding on belt,tape knitting to rope and seed rope rolling can be implemented continually by this machine. The structure parameters of the seed metering device were obtained through theoretical analysis. Effects of rotating speed and negative pressure of the seed metering device on the test indexes were studied by the tests. The results show that the performance indexes of the machine achieve the optimum when the speed of seed metering device is 8-12r/min,the speed of seed belt running is 0. 08-0. 12m/s,and the negative pressure of vacuum room is 2-2. 5k Pa.
