摘　　要：为了进一步提高煤矿水仓清仓机螺旋集泥装置的性能,利用EDEM软件建立了集泥仿真模型,探究了在转速固定传动比不同时集泥装置螺旋铰刀的转矩变化趋势和集料效果,并对得到的数据进行了拟合。结果表明,随着传动比不断增大,单位时间内物料的运送质量也在不断增大,其散点分布近似为一条二次曲线。同时对比不同螺旋铰刀转矩,发现后端螺旋铰刀所受转矩显著高于前端螺旋铰刀,且无明显变化规律,而前端螺旋铰刀转矩在一定范围内随传动比的增加逐渐减小,在传动比为1∶1.1时达到最小。In order to improve the performance of the screw sludge collecting device of the coal mine sump cleaner,a mud collecting simulation model was established using EDEM software.The torque change trend and aggregate effect of the screw reamer of the device underfixed speed and different transmission ratio were explored.The obtained data were fitted and the fitting curve was obtained.The results show that with the increase of transmission ratio,the transportation quality of materials in unit time rises,and the scatter distribution is approximately a quadratic curve.At the same time,through comparing the torque of different spiral reamers,it is found that the torque of the rear spiral reamer is significantly higher than that of the front spiral reamer,and there is no obvious change rule.The torque moment of the front spiral reamer decreases gradually with the increase of the transmission ratio within a certain range,and reaches the minimum when the transmission ratio is 1∶1.1.
