Cutting drum provided with nozzles for shearer loaders or selective-cut heading machines

摘要

The invention relates to a cutting drum (1) which carries nozzles (6) on its basic body (2) or on the helical driver strips (3) of its basic body (2). The nozzles (6) preferably serve to spray high-pressure liquid, are subdivided into individual groups and are connected to liquid lines (8). These liquid lines (8) are located inside the basic body (2) of the cutting drum (1) and run parallel to its rotational axis (20). They start from recesses (10) which are distributed uniformly over the periphery of the basic body (2) and lead out either at the end face of the basic body (2) facing the working face or at the peripheral surface of the basic body (2) or at the peripheral surface of the bore (16) of the basic body (2). All recesses (10) are closed off at their outlet plane, and each of them is connected to a radial feed line (13). The pressure liquid passes via these feed lines (13) to each recess (10), which transfers it to the bores (11) belonging to a nozzle group and running parallel to the axis. IMAGE
