Abstract
A dust and debris extraction device for the purpose of capturing dust and debris created by a chisel held by a power tool has an opening for a chisel to pass through at the front and is guided upward by a sleeve that passes out the top of the body of the device. The extraction end of the device has a locking mechanism to keep a hose going to a negative air source attached. The dust and debris extraction device may either free float on the shank of the chisel or be fixed to the power tool with a bracket.
Claims15
A debris extraction device for attachment to a machining device comprising:
- a body with an internal cavity extending along a central axis of the body;
- a sleeve attached to the body at an angle other than normal to the central axis configured to receive a machining tool;
- an extraction end on the body configured for attachment to a suction device in fluid communication with the internal cavity;
- a suction end on the body opposite the extraction end with a plurality of suction port openings;
- wherein the machining tool extends through the sleeve and into the central axis of the body thereby exiting the body at the suction end;
- and
- wherein the debris extraction device further comprises a wear plate attached to an interior of the suction end, within the internal cavity, with removable fasteners, and wherein the wear plate is capable of contacting the machining tool as the machining tool moves within the sleeve during operation.
