Header with center part and side parts adjustable relative to the center part

摘要

A header of a combine harvester has a center part connected by an attachment frame to the combine feed channel. A first side part with first lateral frame and a second side part with second lateral frame are adjustable for changing their position relative to the center part. The first and second lateral frames are connected by a first ball joint and a second ball joint to the attachment frame, respectively so that the weight of the first and second lateral frames is supported by the first and second ball joints on the attachment frame. The first and second ball joints form first and second pivot axes. An end of the first lateral frame facing away from the center part is pivotable about the first pivot axis. An end of the second lateral frame facing away from the center part is pivotable about the second pivot axis.

主权项

1. A multi-part header for attachment to a combine harvester, the header comprising:
an attachment frame; a center part configured to be connected by the attachment frame to a feed channel of a combine harvester; a first side part comprising a first lateral frame and a second side part comprising a second lateral frame, wherein the first and second lateral frames each are configured to be adjustable so as to change a relative position of the first and second lateral frames to the center part, respectively; the first lateral frame connected by a first ball joint directly to a first end of the attachment frame, wherein a weight of the first lateral frame is supported at least partially by the first ball joint on the attachment frame; the second lateral frame connected by a second ball joint directly to a second end of the attachment frame, wherein a weight of the second lateral frame is supported at least partially by the second ball joint on the attachment frame; wherein the first ball joint forms a first pivot axis and the second ball joint forms a second pivot axis; wherein the first lateral frame comprises an end facing away from the center part and the end of the first lateral frame is pivotable about the first pivot axis; wherein the second lateral frame comprises an end facing away from the center part and the end of the second lateral frame is pivotable about the second pivot axis; wherein the center part is pivotably connected to the attachment frame by hinges, wherein the hinges comprise a hinge axis extending transverse to a forward travel direction of the combine harvester and the center part is configured to change a positioning angle relative to the attachment frame by pivoting about the hinge axis, wherein the hinge axis intersects the first and second ball joints.
