Abstract
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.

A guide assembly for a longwall shearer, the shearer including an arm having an arm end and a cutting drum rotatably coupled to the arm end, the cutting drum rotating about a drum axis and engaging a mine wall, the cutting drum having a rear extent arranged in a plane substantially perpendicular to the drum axis, the assembly comprising:
- a guide member coupled to the arm and operable to guide material won from the mine wall, the guide member extending substantially perpendicular to the drum axis and being arranged to not cross the plane.
A guide assembly for a longwall shearer, the shearer including an arm having an arm end and a cutting drum rotatably coupled to the arm end, the cutting drum rotating about a drum axis and engaging a mine wall, the cutting drum having a rear extent arranged in a plane substantially perpendicular to the drum axis, the assembly comprising:
- a guide member coupled to the arm and operable to guide material won from the mine wall, the guide member having a guide surface extending in a direction non-parallel to the plane and non-parallel to the drum axis, the guide member guiding material along the guide surface away from the cutting drum.
A guide assembly for a longwall shearer, the shearer including an arm having an arm end and a cutting drum rotatably coupled to the arm end, the cutting drum rotating about a drum axis and engaging a mine wall, the cutting drum having a rear extent arranged in a plane substantially perpendicular to the drum axis, the assembly comprising:
- a hub portion coupled to the arm and pivotable about a hub axis;
- and
- a guide member connected to and pivotable with the hub portion, the guide member extending perpendicular to the drum axis and being arranged to not cross the plane, the guide member including a flap formed at least partially of a flexible material, the flap deflecting material won from the mine wall and traveling in a direction non-parallel to the plane.
A longwall shearer for engaging a mine wall, the shearer comprising:
- a body;
- an arm including a first end coupled to the body and a second end;
- a cutting drum rotatably coupled to the arm end, the cutting drum rotating about a drum axis and engaging a mine wall, the cutting drum having a rear extent arranged in a plane substantially perpendicular to the drum axis;
- and
- a guide member coupled to the arm and operable to guide material won from the mine wall, the guide member extending substantially perpendicular to the drum axis and being arranged to not cross the plane.
