Abstract
A rake frame subassembly includes a front frame segment and a rear frame segment connected by a hinge joint having two or more hinges and an adjustment element. The hinge joint connects or is configured to connect the front frame section and the rear frame section. The hinge joint is also configured to enable both an orientation of the rear frame section relative to the front frame section and a position of the rear frame section relative to the front frame section to be adjusted using the adjustment element, or is configured to enable a position of the rear frame section relative to the front frame section to be adjusted using the adjustment element.
Claims20
A rake frame subassembly comprising:
- a front frame section configured to support at least one front rake wheel;
- a rear frame section configured to support at least one rear rake wheel;
- and
- a hinge joint having:
- a first hinge and a second hinge, each connected to, attached to, integral with, configured to connect to, or configured to be integral with the front frame section;
- and
- a third hinge and a fourth hinge, each connected to, attached to, integral with, configured to connect to, or configured to be integral with the rear frame section, each of the first hinge, second hinge, third hinge, and fourth hinge having an axis of rotation that does not overlay an axis of rotation of others of the first hinge, second hinge, third hinge, and fourth hinge,
- the hinge joint comprising an adjustment element configured to adjust a distance between a rotation axis of the first hinge and a rotation axis of the fourth hinge,
- the hinge joint connecting or configured to connect the front frame section and the rear frame section and configured to:
- enable both an orientation of the rear frame section relative to the front frame section and a position of the rear frame section relative to the front frame section to be adjusted by changing an orientation of the rear frame section relative to the front frame section and translating the rear frame section relative to the front frame section using the adjustment element;
- or
- enable a position of the rear frame section relative to the front frame section to be adjusted by translating the rear frame section relative to the front frame section using the adjustment element.
A hinge joint configured to connect a trailing end of a front frame section of a rake frame subassembly and a leading end of a rear frame section of the rake frame subassembly, the hinge joint having a first hinge, a second hinge, a third hinge, and a fourth hinge and comprising:
- a first hinge plate configured to connect to or be attached to an inner side of front frame section at the trailing end;
- a second hinge plate configured to connect to or be attached to an outer side of the front frame section at the trailing end;
- a third hinge plate configured to connect to or be attached to the inner side of the rear frame section at the leading end;
- a fourth hinge plate configured to connect to or be attached to the outer side of the rear frame section at the leading end;
- at least one inner control arm, a first end of the at least one inner control arm rotatably connected with or configured to rotatably connect with the first hinge plate at the first hinge, a second end of the at least one control arm rotatably connected with or configured to rotatably connect with the third hinge plate at the third hinge;
- at least one outer control arm, a first end of the at least one outer control arm rotatably connected with or configured to rotatably connect with the second hinge plate at the second hinge, and a second end of the at least one outer control arm rotatably connected with or configured to rotatably connect with the fourth hinge plate at the fourth hinge;
- and
- an adjustment element configured to adjust a distance between the first hinge and the fourth hinge, thereby adjusting a position of the rear frame section relative to the front frame section, or thereby adjusting both an orientation of the rear frame section relative to the front frame section and a position of the rear frame section relative to the front frame section.
