Abstract
The present disclosure relates to grinders in the form of a planer or drum grinder for milling surfaces such as asphalt or concrete. The planer has a multiplicity of cutters oriented in selected arrangements. It is described in the context of a representative system that is added to prime movers, such as skid-steer loaders.
Claims14
A planer for milling a surface, comprising:
- a. a rotatable shaft to be moved over a surface to be ground in a direction of travel and defining an axis of rotation;
- b. a plurality of first elliptical plates each fixedly arranged in a non-perpendicular angle relative to the axis of rotation and each carrying a set of cutters arranged so that as the shaft rotates, the cutters each orbit in a circle of constant radius around the axis of rotation defining a first circular cylindrical section with a first cylindrical radius;
- c. a second plate fixedly arranged on said shaft, wherein said second plate is circular and arranged perpendicular to the axis of rotation and carrying a second set of cutters arranged so that as the shaft rotates the second set of cutters each orbit circularly around the axis of rotation defining a second radius;
- and,
- d. wherein said plurality of first elliptical plates is arranged on opposing sides of said second plate and wherein the second radius is significantly greater than the the first radius and configured so that the second plate cuts a slot with a relatively thin width yet significantly greater depth than the cuts made by the plurality of first elliptical plates.

A planer for milling a surface, comprising:
- a. a rotatable shaft to be moved over a surface to be ground in a direction of travel and defining an axis of rotation;
- b. two sets of first cutters supported on said shaft at a first cylindrical radius and arranged in an angled elliptical pattern so that as the shaft rotates, the first cutters each orbit in a circle around the axis of rotation;
- c. a set of second cutters supported on said shaft at a second radius and arranged in an angled elliptical pattern so that as the shaft rotates about its axis of rotation the second cutters orbit circularly around the axis of rotation;
- and,
- d. wherein the set of second cutters is arranged between said two sets of first cutters and wherein the second radius is less than the first radius so that the two sets of first cutters and the set of second cutters form an alternating pattern with the set of second cutters cutting an upward stepped portion between downward stepped portions cut by the two sets of first cutters.
2 more elements
A planer for milling a surface, comprising:
- a. a rotatable shaft to be moved over a surface to be ground in a direction of travel and defining an axis of rotation;
- b. at least one angled plate with an apex portion coaxially aligned with said shaft, and with a pair of portions angled in a concave arrangement diverging from said apex on opposing sides of said shaft;
- c. a set of cutters arranged on said plate so that as the shaft rotates, each cutter orbits in a circle of constant radius around the axis of rotation and within a plane perpendicular to said axis of rotation;
- and,
- d. wherein at least a first cutter on said plate is in a first vertical plane and defines a first radius, wherein at least a second cutter on said plate is in a second vertical plane and defines a second radius and wherein the second radius is different from the first radius.
