螺旋钻参数对挖坑出土效能的影响

为了解决螺旋钻挖坑作业中存在的效率低、效果不佳等问题,进行了螺旋钻田间挖坑试验,通过改变直径、螺旋数量和转速等螺旋钻参数进行挖坑及出土情况测试,测取了坑形、抛土半径和出土率等特征数据,运用单因素方差分析和析因设计方差分析等方法进行了试验数据处理.研究结果表明:转速一定的情况下,螺旋钻直径增大,抛土半径和出土率增大;增加...

Influence of Auger Bit Parameters on Digging Efficacy

In order to solve problems of low efficiency and poor effect in auger digging operation, digging test with auger was conducted in the field.By changing auger parameters such as diameter, screw number and rotation speed to carry out digging and soil exit conditions test, characteristic data were measured such as pit shape, throwing soil radius, and soil exit rate.The experimental data were processed using methods such as one-way analysis of variance and factorial design analysis of variance.Results showed that: when rotation speed was constant, diameter of auger increased, throwing soil radius and soil exit rate increased.Increasing rotation speed would increase throwing soil radius and soil exit rate.The double-headed double auger had a smaller throwing soil radius and higher soil exit rate than double-headed single auger.The analysis showed that different parameters of auger had a significant impact on soil exit situation.The research results could provide theoretical support for actual digging operation of auger digging machine.
