Role of Lifting Angles of Coal Mining Machine Blades on the Influence of Cutting Drums
Coal mining machine is an important equipment of coal mine automation,and the blade lifting angle is an important design parameter in the structure of the drum,which has an important influence on the number and direction of the cut-off teeth of the drum,and thus affects the mining efficiency of the coal mining machine and the lump coal rate.In order to analyse the loads on the drum of coal mining machine,the numerical analysis model of drum cut-off is established under different blade lifting angles,and the average resistance,maximum resistance,load fluctuation coefficient and energy consumption of cut-off ratio are calculated and analyzed,so as to provide references for the design of the drum of coal mining machine.
