A rotary hammerbreaker including a plurality of discs driven upon a rotor shaft, a plurality of rods extending through the discs parallel to the rotor shaft and radially spaced therefrom and a plurality of hammers pivotably mounted upon the rods between the discs. The hammerbreaker is provided with a protective device consisting of a plurality of shields each including a hub mounted upon one of the rods between adjacent discs. The shields are formed with a circular segmental flange fixed to the hub extending over a part of the periphery of each of the adjacent discs between which the hub is mounted to protect the disc periphery. The flange has a circumferentially extending portion which is an integral fraction of a whole circle so that a number of the shields can be fitted to a rotary hammerbreaker to provide substantially continuous protection around the periphery of the discs.
A protective device for a rotary hammerbreaker including a plurality of discs secured upon a rotor shaft, a plurality of rods extending through said discs and hammers pivotably mounted upon said rods between said discs, said protective device comprising a plurality of shields each including a hub mounted upon one of said rods between adjacent discs, and a circumferential segmental flange fixed to said hub extending over at least a part of the periphery of at least one of the adjacent discs between which said hub is mounted to protect said part of said periphery, each of said segmental flanges being configured to extend over a portion of the circumference of said hammerbreaker with said plurality of shields being fitted to said rotary hammerbreaker such that said segmental flanges are juxtaposed relative to each other to provide substantially continuous protection over the periphery of said discs.
