Research on the Cutting Characteristics of Coal Miner Drum under Different Viscous Coal Bodies
In order to improve the cutting efficiency under the environment of complex viscous coal body,numerical simulation software is used to analyse the cutting characteristics under different viscous coal bodies.Firstly,the force of the spiral drum and the number of cemented particles of coal and rock are analysed under the coal rock of different viscosity,and it is found that the force of the spiral drum is gradually increased with the increase of viscosity,and the number of cemented particles of coal and rock is less and less in the same time,and the force situation of the spiral drum is analysed under the three-way force under the different traction speeds.Afterwards,the force in three directions under different traction speeds is analysed,and it is found that the force in x,y and z directions of the spiral drum shows the trend of increasing gradually with the increase of traction speed,which provides certain reference for the high efficiency of cutting of the spiral drum of the coal mining machine.
