Abstract
A cutting assembly for a header of a plant-cutting machine includes a blade assembly fastened to a head assembly, which is configured to be drivingly connected to a motor. The cutting assembly is suitable for mounting proximate to the center of the header, in an end-to-end relation with another cutting assembly. Removal of the blade assembly from the head assembly can be efficiently effected by releasing or removing a small number of fasteners, thus allowing an operator to readily remove or replace the blade assembly as needed.
Claims21
A knife head assembly for a header of an agricultural cutting machine, the knife head assembly comprising:
- an elongate head attach bar having a major axis, the elongate head attach bar comprising:
- a first surface being configured to form a flush contact with a blade assembly;
- a series of first fastener-receiving through-openings, each first fastener-receiving through-opening of the series passing through the first surface and a second surface, the series of first fastener-receiving through-openings being substantially perpendicular to the major axis;
- and
- a projection extending from the second surface and disposed on a distal end thereof the projection having a second fastener-receiving through-opening passing through the first and second surfaces;
- and
- a connecting block disposed about the projection such that the connecting block is elevated above the second surface, the connecting block being configured to receive a driver element, the connector block includes a connecting block through-opening, the connecting block being configured to retain a bearing unit in the connecting block through-opening, the bearing unit having a bearing through-opening, wherein the respective center axes of the second fastener-receiving through-opening, the connector block through-opening and the bearing unit through-opening are substantially coaxial along a minor axis, wherein the minor axis is substantially perpendicular to the major axis.
A cutting assembly suitable for mounting proximate to the center of a header of a plant-cutting machine, the cutting assembly comprising:
- a head assembly comprising:
- an elongate head attach bar having a major axis, the elongate head attach bar comprising:
- a first surface being configured to form a flush contact with a blade assembly;
- a series of first fastener-receiving through-openings, each first fastener-receiving through-opening of the series passing through the first surface and a second surface, the series of first fastener-receiving through-openings being substantially perpendicular to the major axis and being configured to receive a series of removable fasteners therethrough;
- and
- a projection extending from the second surface and disposed on a distal end thereof, the projection having second fastener-receiving through opening passing through the first and second surfaces;
- and
- a connecting block disposed about the projection such that the connecting block is elevated above the second surface, the connecting block being configured to receive a driver element, the connector block includes a connecting block through-opening, the connecting block being configured to retain a bearing unit in the connecting block through-opening, the bearing through-opening, wherein the respective center axes of the second fastener-receiving through-opening, the connector block through-opening and the bearing unit through-opening are substantially coaxial along a minor axis, wherein the minor axis is substantially perpendicular to the major axis.
A header for a plant-cutting machine comprising:
- a first cutting assembly drivingly connected proximate the center of the header;
- a second cutting assembly drivingly connected proximate the center of the header, the second cutting assembly being in an end-to-end relation with the first cutting assembly and being substantially coaxial to the first cutting assembly, the second cutting assembly comprising:
- a head assembly comprising:
- an elongate head attach bar having a major axis, the elongate head attach bar comprising:
- a first surface being configured to form a flush contact with a blade assembly;
- a series of first fastener-receiving through-openings, each first fastener-receiving through-opening of the series passing through the first surface and a second surface, the series of first fastener-receiving through-openings being substantially perpendicular to the major axis and being configured to receive a series of removable fasteners therethrough;
- and
- a projection extending from the second surface and disposed on a distal end thereof, the projection having a second fastener-receiving through-opening passing through the first and second surfaces;
- and
- a connecting block disposed about the projection such that the connecting block is elevated above the second surface, the connecting block being configured to receive a driver element, the connector block includes a connecting block through-opening, the connecting block being configured to retain a bearing unit in the connecting block through-opening, the bearing unit haying a h-opening, wherein the respective center axes of the second fastener-receiving through-opening, the connector block through-opening and the bearing unit through-opening are substantially coaxial along a minor axis, wherein the minor axis is substantially perpendicular to the major axis.
