摘要
脱粒是水稻、小麦等农作物收获中必不可少又至关重要的一道工序。联合收割水稻时总是存在脱粒损伤和带柄的问题,为后续的作业带来诸多不便。为此,针对这些影响因素,对北方常见的几种寒地水稻用OM-8650拉压机对水稻穗头主茎秆与枝梗、枝梗与粒柄以及籽粒与粒柄之间连接力进行测试。结果表明,不同的水稻品种、不同的生长部位、不同的含水率以及不同的受力方向对连接力都有影响。运用DPS数据处理系统建立水稻的含水率与连接力之间的关系模型,为确定最佳脱粒时间和设计脱粒滚筒奠定良好的基础。
The threshing in the rice and wheat crops harvest is an essential and very important working procedure,United for the rice harvest threshing damage and there is always the problem with handle,for the follow-up work to bring a lot of inconvenience.In this paper,these factors to the north of several common cold to rice with 8650 pull compressor OM ear of rice stem head lord with primary branches,primary branches and grain handle and grain and grain between handle even test,the relay results show that different rice varieties,the growth of different parts,the moisture content of different and different stress direction even relay to have impact.The data processing system is established by DPS the moisture content of rice and even the relay the relation model between,for sure the best threshing time and design threshing roller lay the good foundation.
