Dust scrubber

摘要

A dust scrubber for a mining shearer machine is adapted to be mounted behind the rear surface of the shearer arm, on the opposite side of the arm to the mine surface being cut, so as to extract airborne particulates. The scrubber may be mounted to the shearer via a compensation mechanism such as a double hinge and link arrangement which maintains relatively static position and/or orientation of the scrubber despite the pivoting of the shearer arm in operation.

1. A dust suppression arrangement for use with a mining shearer which includes a movable shearer arm attached to a shearer body, the dust suppression arrangement comprising:
a dust suppression unit and a mounting for mounting the dust suppression unit to the shearer arm, the mounting including a compensation mechanism that adjusts at least one of position and orientation of the dust suppression unit relative to the shearer arm responsive to movement of the shearer arm relative to the shearer body; wherein the compensation mechanism includes a double hinge arrangement which acts to maintain orientation of the dust scrubber unit relative to the shearer body generally static irrespective of pivoting movement of the shearer arm relative to the shearer body, and a flexible link between the dust suppression unit and the shearer body so as to actuate the double hinge arrangement.
