用于长壁采煤机的刀头
摘要：
一种用于长壁采煤机的刀头，包括筒、叶片以及多个切削钻头。筒包括第一端和第二端，并限定在第一端与第二端之间延伸的旋转轴线。叶片连接到筒，且以螺旋的方式沿着轴线的至少一部分延伸。叶片限定沿着叶片的外周延伸的刃表面。切削钻头被固定到叶片的刃表面。每个切削钻头包括块和联接到该块的钻头。块被固定到刃表面，且延伸超出到叶片的外周之外。
摘要（英）：

A cutter head for a longwall shearer includes a drum, a vane, and a plurality of cutting bits. The drum includes a first end and a second end and defines an axis of rotation extending therebetween. The vane is connected to the drum and extends in a helical manner along at least a portion of the axis. The vane defines an edge surface extending along an outer perimeter of the vane. The cutting bits are secured to the vane edge surface. Each cutting bit includes a block and a bit coupled to the block. The block is secured to the edge surface and extends beyond the outer perimeter of the vane.
