Material guide assembly

摘要

A guide assembly for a longwall shearer. The shearer includes an arm having an arm end and a cutting drum rotatably coupled to the arm end. The cutting drum rotates about a drum axis and engages a mine wall, and the cutting drum has a rear extent arranged in a plane substantially perpendicular to the drum axis. The guide assembly includes a guide member coupled to the arm and operable to guide material won from the mine wall. The guide member has a guide surface extending in a direction non-parallel to the plane and non-parallel to the drum axis. The guide member guides material along the guide surface away from the cutting drum.
