Abstract
Differential speed stalk rolls mountable to a row unit of a row crop head. A first stalk roll body has an outer peripheral speed less than the outer peripheral speed of a second stalk roll body in lateral spaced relation. At least one of the first and second bodies includes a knife defining a knife plane normal to the axis of rotation of the first or second stalk roll. The stalk roll bodies may have modular and interchangeable body segments of different configurations.
Claims24
A differential speed stalk roll assembly mountable to a row unit of a row crop head, comprising:
- a first stalk roll comprising a first body mountable to a first shaft rotatable about a first axis of rotation at a first shaft RPM, the first body having an outer diameter with an outer periphery;
- a second stalk roll comprising a second body mountable to a second shaft in lateral spaced relation to the first shaft, the second shaft rotatable about a second axis of rotation at a second shaft RPM, the second body having an outer diameter with an outer periphery;
- wherein the outer periphery of the second body rotates at a speed greater than the outer periphery of the first body;
- and
- wherein at least one of the first body and second body includes at least one knife defining a knife plane normal to the first and second axis of rotation.
A differential speed stalk roll assembly mountable to a row unit of a row crop head, comprising:
- a first stalk roll body secured to a first stalk roll shaft of the row unit, the first stalk roll shaft rotatable about a first axis of rotation, the first stalk roll body comprising a plurality of first modular plate segments, the plurality of first modular plate segments defining a first stalk roll body diameter;
- a second stalk roll body secured to a second stalk roll shaft of the row unit, the second stalk roll shaft rotatable about a second axis of rotation, the second stalk roll body comprising a plurality of second modular plate segments, the plurality of second modular plate segments defining a second stalk roll body diameter, the second stalk roll body diameter being greater than a laterally adjacent portion of the first stalk roll body diameter;
- and
- at least one annular knife disposed on either said first stalk roll body or said second stalk roll body, the at least one annular knife defining a knife plane normal to the first and second axis of rotation.
