【摘要】 螺旋钻采煤机可以有效的对薄与极薄煤层进行开采。而螺旋钻采煤机的钻头作为采煤机的核心部分,对截煤性能有着极大的影响。主要对钻头载荷进行分析,建立钻头截齿的受力分析图,并且以钻头的不同结构对截煤性能的影响进行仿真试验,研究其对截煤性能的影响。更多还原

【Abstract】 The coal auger is efficient on the thin and ultra-thin seam. As the key component of the coal auger, the cutting bit almost determines the coal cutting performance of the machine. Mainly analyzes the load on the cutting bit and establishes the stress analysis diagram of tooth. Also, stimulates the relationship between cutting bit structure and coal cutting performance.更多还原
