Harvester machine having at least one height elastic lateral frame

The pith
A harvesting machine uses pivotable lateral frames and trailing arms to link ground supports to its height control system.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The harvesting machine comprises an intake channel connected to a height control, an attachment frame fixed to the intake channel, at least one lateral frame pivotably attached to the side of the attachment frame, a ground support carried by the lateral frame, and a trailing arm that is pivotably connected both to the lateral frame and to the ground support.
What carries the argument
The trailing arm that pivotably links each lateral frame to its ground support, allowing independent vertical motion of the side frame relative to the attachment frame.
If this is right
- The lateral frames can rise and fall independently on each side of the header.
- Ground contact forces are transmitted through the trailing arm rather than solely through the pivot joint on the attachment frame.
- The height control actuator on the intake channel can still lift or lower the entire assembly while the side frames continue to follow local terrain.
- Reduced rigid connection between outer ground supports and the central frame lowers peak bending moments at the attachment points.
Where Pith is reading between the lines
- The design could reduce missed crop on headlands or terraces where one side of the header encounters a ridge the other does not.
- Similar trailing-arm linkages might be applied to other ground-following implements such as mowers or tillage tools that currently rely on rigid or purely spring-loaded wings.
- If the trailing arm geometry is tuned to a particular ground-support wheel radius, the vertical path of the lateral frame becomes approximately parallel to the ground over the normal operating height range.
Load-bearing premise
This specific kinematic linkage will in practice deliver measurable improvement in height control or reduced structural stress compared with existing header designs.
What would settle it
Side-by-side field trials that measure header height variance over uneven ground and structural loads at the attachment points for this configuration versus a conventional rigid or spring-mounted header.

1 . A harvesting machine ( 2 ) comprising: an intake channel ( 10 ) that is connected to a height control ( 70 ), wherein the height control ( 70 ) lifts or lowers the intake channel ( 10 ); an attachment frame ( 8 ) that is connected to the intake channel ( 10 ); at least one lateral frame ( 78 ) pivotably connected to the attachment frame ( 8 ) at a side; at least one ground support ( 80 ) attached to each lateral frame ( 78 ); and at least one trailing arm ( 82 ) that is pivotably connected to the respective at least one lateral frame ( 78 ), and the at least one trailing arm ( 82 ) is fastened to the at least one ground support ( 80 ).
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The manuscript is a utility patent disclosing a harvesting machine (2) whose central claim is a kinematic arrangement consisting of an intake channel (10) actuated by a height control (70), an attachment frame (8), at least one lateral frame (78) pivotably mounted to the attachment frame, a ground support (80) attached to each lateral frame, and a trailing arm (82) pivotably connecting the lateral frame to the ground support.
Significance. The configuration supplies a concrete, parameter-free mechanical linkage that can in principle allow passive elastic height adjustment of header elements. Because the disclosure contains no equations, force balances, or performance metrics, its contribution is limited to the novelty of the described pivot geometry rather than any demonstrated improvement in stress reduction or terrain following.
minor comments (1)
- [Title and claim 1] The title uses the phrase 'height elastic lateral frame,' yet the claim language never defines or quantifies elasticity; a single clarifying sentence linking the trailing-arm geometry to elastic behavior would improve readability.
Simulated Author's Rebuttal
We thank the referee for the careful reading and for recommending acceptance. The report correctly identifies that the disclosure centers on the specific pivot geometry and trailing-arm linkage rather than on derived performance metrics.
Circularity Check
No significant circularity
full rationale
The document is a utility patent whose sole load-bearing content is a mechanical configuration claim (intake channel + pivotable lateral frame + trailing arm + ground support). No equations, fitted parameters, predictions, derivations, or self-citations appear anywhere in the text. The claim is therefore not reducible to any input by construction and receives the default non-circularity finding.
