Abstract
A cutting drum for a scarifying milling machine includes a rotatable drum having a generally cylindrical outer surface, and a plurality of flight blocks mounted onto the outer surface of the drum, defining a helical flight extending therearound. Each of the flight blocks includes a slot and at least one pocket formed therein. Each slot is generally rectangular and adapted to receive a tool holder. Each flight block includes a tool holder, having a generally rectangular body, removably mounted within the slot. A retainer is positioned within each pocket. Each retainer includes a planar tapered surface that is parallel to and engages one side of the rectangular body of the tool holder within the slot of the flight block to secure the tool holder therein.

A cuffing drum for a scarifying milling machine comprising:
- a rotatable drum having a generally cylindrical outer surface;
- a plurality of flight blocks mounted onto the outer surface of the drum, the flight blocks being positioned onto the drum relative to one another such that the flight blocks define a helical flight extending around the outer surface of the drum;
- each of the flight blocks including a first side wall, a second side wall, and a top surface, the first and second side walls being generally parallel to one another and generally perpendicular to the drum, the top surfaces of the flight blocks defining an outer periphery of the flight;
- each of the flight blocks including a slot and at least one pocket formed therein, each slot being generally rectangular and adapted to receive a tool holder and including first and second slot side walls, a bottom surface and a rear slot wall, the first and second slot side walls being generally parallel to one another and generally perpendicular to the rear slot wall, and the rear slot wall being oriented at an angle relative to the first and second side walls of the flight block, the at least one pocket intercepting the slot;
- a plurality of tool holders having a generally rectangular body dimensioned to be received within the slot of a flight block, one tool holder being removably mounted within the slot of each flight block;
- a plurality of retainers, one retainer being positioned within each pocket of each flight block, each retainer including a planar laterally tapered surface that is parallel to and engages one side of the rectangular body of the tool holder within the slot of the flight block to secure the tool holder therein.
A flight block adapted to be mounted onto a cutting drum for a scarifying milling machine comprising:
- a first side wall, a second side wall, and a top surface, the first and second side walls being generally parallel to one another and generally perpendicular to the top surface;
- a slot formed within the first side wall and extending through the top surface, the slot being generally rectangular and adapted to receive a tool holder and including first and second slot side walls, a bottom surface and a rear slot wall, the first and second slot side walls being generally parallel to one another and generally perpendicular to the rear slot wall, and the rear slot wall being oriented at an angle relative to the first and second side walls;
- at least one pocket formed within the first side wall and intercepting the slot;
- a tool holder having a generally rectangular body dimensioned to be received within the slot and being removably mounted within the slot;
- a retainer positioned within each pocket, each retainer including a planar laterally tapered surface that is parallel to and engages one side of the rectangular body of the tool holder to secure the tool holder within the slot.
A flight block adapted to be mounted onto a cutting drum for a scarifying milling machine comprising:
- a first side wall, a second side wall, and a top surface, the first and second side walls being generally parallel to one another and generally perpendicular to the top surface;
- a slot formed within the first side wall and extending through the top surface, the slot being generally rectangular and adapted to receive a tool holder and including first and second slot side walls, a bottom surface and a rear slot wall, the first and second slot side walls being generally parallel to one another and generally perpendicular to the rear slot wall, and the rear slot wall being oriented at an angle relative to the first and second side walls;
- at least two pockets formed within the first side wall and oriented substantially perpendicular to the first wall and intercepting the slot;
- a tool holder having a generally rectangular body dimensioned to be received within the slot and being removably mounted within the slot;
- a retainer positioned within each pocket, each retainer including a planar laterally tapered surface that is parallel to and engages one side of the rectangular body of the tool holder to secure the tool holder within the slot.
