A milling machine can include a frame, a milling assembly including a cutting rotor and a rotor housing coupled to the frame, the cutting rotor including a rotor shell positioned around a spindle, and a first axial alignment feature on one of the rotor shell or the spindle, the first axial alignment feature including a physical feature on a surface of the rotor shell or the spindle, the physical feature being positioned and configured to contact an opposing flat surface of the opposing rotor shell or spindle so as to guide the rotor shell and the spindle into a co-axial alignment as the rotor shell is loaded axially onto the spindle.

Quick change rotor alignment feature

A bit removal device may include a support, an extractor coupled to the support, and an actuator. The support is configured to engage a bit holder from a front side of the bit holder. The extractor is configured to engage a bit from the front side of the bit holder. The actuator is configured to move the extractor relative to the support to extract the bit from the bit holder.

Rotor bit removal device

A bit holder can include a body and a collar. The body can be mountable to a rotor of a piece of equipment. The collar can be coupled to the body and can be configured to receive the bit therein. The collar can include a first flat collar surface forming a portion of a radially outer surface of the collar and a second flat collar surface forming a portion of the radially outer surface of the collar.

Toolholder with provisions for bit removal

A paddle for a reclaiming drum may include a block of material configured for attachment to a leading edge of a flighting supporting a cutting bit on the reclaiming drum, and the block of material may assist in breaking up and mixing material removed from a surface by the cutting bit as the reclaiming drum is rotated and moved into the surface. The paddle may include two ear portions protruding from opposite sides of a flat, centrally-located, aft-facing surface of the block of material, each of the ear portions including an inwardly-facing chamfered surface configured to interface with an outwardly-facing, leading edge chamfered surface of the flighting such that a gap is maintained between a flat leading edge surface of the flighting located in between the outwardly-facing chamfered surfaces and the flat, centrally-located, aft-facing surface of the block of material when the block of material is attached to the flighting.

Reclaiming drum having interchangeable rectangular and V-shaped paddles

A mounting block assembly and method for assembling is disclosed. The mounting block assembly may comprise a mounting block and a toolholder. The mounting block may include a flighting portion, a mounting portion and a protrusion. The mounting portion defines a first bore that is configured to receive a toolholder. The toolholder includes a generally cylindrical sidewall that defines an axis and defines a second bore that is configured to receive a stem of a cutting bit. The sidewall includes a pair of radially outward extending prongs that define a first recess between the prongs. The first recess is configured to interlockably receive the protrusion when the toolholder is disposed in the mounting portion, wherein the interlocked configuration of the toolholder and the mounting block inhibit rotational movement of the toolholder about the axis.

Locking system to prevent rotation of toolholder

A tool adapter comprises a body including at least one elongated portion defining a longitudinal axis, a first end and a second end disposed along the longitudinal axis, a flange disposed between the first and second ends along the longitudinal axis, and an exterior surface extending along the longitudinal axis, and a collar portion defining a collar outer surface and the body defines a first groove disposed adjacent the first end extending along the longitudinal axis on the outer collar surface along the majority of the longitudinal length of the collar portion.
