A tool mounting for a planing machine in which the cutting tools are exposed to high tangential forces. The tool is held on a rotary drum by a wedging action so as to be more readily replaced. The tool may comprise separate adapter and cutter bit components, or in the form of a one-piece member. The tool adapter includes a projection extending from an end opposite from the cutting tool. The projection includes a first contact surface and the mounting includes a second contact surface located outwardly from the first contact surface which first and second contact surfaces converge toward one another. In this way, the first and second contact surfaces cooperate with corresponding surfaces on the cutting head to wedgingly secure the adapter thereto. In a further embodiment of the present invention, the adapter includes a through-hole communicating with the bore for receiving the tool such that a projection on the recessed casing for the tool can enter the through-hole and the bore to rotatably mount the tool whereby disengagement of the adapter also disengages the tool from the adapter.
In combination, a planing machine for pavement profiling comprising a rotating drum having a helical ring mounted thereon and having a single rotational direction, and a tool mounting comprising:
A planing machine for pavement profiling comprising:
The combination of a cutter drum and cutting tool holders for a road planing machine, said cutter drum having a helical ring mounted thereon and each holder being mounted by a tongue and groove connection comprising:
A tool holder for use on a machine of the type having a radius and radially spaced contact surfaces, said tool holder including inner and outer contact surfaces which converge and are adapted to engage the first-named contact surfaces of the machine for securing said holder to the machine by wedge action such that the machine radius passes through a tip of the tool;
A cutting tool adapter intended to receive a cutting tool and to be attached to a cutting head of a machine for extraction of earth formations, said adapter having a projection which projects from said adapter at an end thereof opposite to the cutting tool, said projection including a first contact surface, said adapter including a second contact surface located outwardly of said first contact surface and adapted for contact with said cutting head, said first and second contact surfaces extending at an angle relative to one another, and a bore in said adapter for receiving said cutting tool.
A tool holder adapted for wedging connection within a correspondingly shaped slot of a cutting head, said tool holder comprising:
