Description

Technical Field

[0001] The utility model relates to the technical field of bolter digging machines, in particular to a coal guiding inclined plate for protecting a tooth seat at the end of a bolter digging machine drum. Background Art

[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] The cutting teeth of the anchor mining machine drum cannot cut through the coal wall at the frame. The harder material will form a coal ridge with the same width and higher thickness as the frame on the coal wall. This coal ridge can only be squeezed and crushed by the coal breaking teeth and cockscomb teeth on the frame. The crushed materials are large and most of them are gathered in the gap between the drum and the frame. When the material is highly abrasive, it is very easy to cause the tooth seat of the anchor mining machine drum close to the frame to form eccentric wear on one side of the frame. The increased wear speed of the tooth seat seriously affects the overall service life of the drum and affects the user's production schedule. Utility Model Content
