Abstract
A cutting roll of the type with a cylindrical base member and at least one substantially axially-parallel blade attached thereto for separation of sugarcane, sweet sorghum, and the like. Grooves in the base have serrated walls engaging serrated sides of blade members, and wedging members secure the blades in proper radial adjustment in the grooves. A plurality of blade segments in each groove and a slight angling of the serrations allows blade rotation and provides a highly accurate and easily adjustable cutting roll.
Claims31
In a cutting roll of the type with a cylindrical base member and at least one substantially axially-parallel blade attached thereto, the improvement comprising for each blade:
- a substantially axially-parallel groove in the base member having a first substantially radial wall with parallel serrations extending therealong;
- a blade having an outer edge and first and second sides, the first side being serrated to mate with the serrated wall of the groove, the blade having a plurality of blade segments arranged in end-to-end contact in the groove, the blade segments each having an outer edge, a first side and a second side aligned with the outer edges, first sides and second sides, respectively, of other blade segments such that the blade segments together form the outer edge, first side and second side of the blade;
- a blade anchor secured in the groove to force the first side of the blade toward the first wall of the groove to removably secure the blade in the groove in proper radial adjustment;
- and
- the groove wall serrations extending in a direction which is angled with respect to the axis of the cylinder, whereby the angle being such that over the length of the groove the serrations increase in radius by a distance up to the width of one serration, movement of blade segments along the groove wall serrations while engaged therewith moves such blade segments radially outwardly.
In a sugarcane separation apparatus of the type having means for splitting billets and a cutter roll for removing the pith from the rind of such split billets, such cutter including a cylindrical base member and at least one substantially axially-parallel blade attached thereto, the improvement comprising for each blade:
- a substantially axially-parallel groove in the base member having a first substantially radial wall with parallel serrations extending therealong;
- a blade having an outer edge and first and second sides, the first side being serrated to mate with the serrated wall of the groove, the blade having a plurality of blade segments arranged in end-to-end contact in the groove, the blade segments each having an outer edge, a first side and a second side aligned with the outer edges, first sides and second sides, respectively, of other blade segments such that the blade segments together form the outer edge, first side and second side of the blade;
- means to force the first side of the blade toward the first wall of the groove to removably secure the blade in the groove in proper radial adjustment;
- and
- the groove wall serrations being extending in a direction which is angled with respect to the axis of the cylinder, whereby the angle being such that over the length of the groove the serrations increase in radius by a distance up to the width of one serration, movement of blade segments along the groove wall serrations while engaged therewith moves such blade segments radially outwardly.
