[0002] The anchor-digger is a highly integrated coal mine tunnel fast digging equipment that integrates digging, support and dust prevention, and has the characteristics of safety, efficiency and greenness. The anchor-digger drum is mainly divided into three parts: the middle drum, the fixed drum and the telescopic drum; and it is divided into left and right drums in the direction facing the anchor-digger driver in the cab, and the left and right drums are symmetrical to each other.

[0003] According to the attached drawings in the specification Figure 3 The structural diagram of the internal structure of the middle fixed drum and the outer telescopic drum before improvement. To ensure the smoothness of the cross section of the telescopic drum after it is extended, part of the tooth seat will be lower than the outer end surface of the fixed drum after the telescopic drum is recovered. Therefore, the fixed drum has a groove on the outermost side for the placement of the tooth seat after the telescopic drum is recovered. During the application process, the inner telescopic drum and the outer end of the fixed drum are cantilever beam force structures, which are prone to breakage at the groove at the outer end of the fixed drum, breakage of the telescopic drum tooth seat with pad, serious deformation of the keyway on both sides of the outer open end of the telescopic drum body, and looseness and easy to fall off. At the same time, the overall rock breaking ability of the anchor mining machine drum is seriously insufficient, so it needs to be improved. Utility Model Content
