The pith

A harvester auger pan nozzle uses progressively slanting vanes to direct air toward the discharge.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The patent describes a harvester head with a gathering assembly, outlet, and conveying system that includes an auger and a parallel pan. The pan has a trough portion on one side leading to an auger discharge. A first nozzle runs along the opposite edge and blows air into the trough bottom. The nozzle features vanes that form a series of openings spaced along its length, each aimed at the discharge, with the vanes shifting from perpendicular at the center to more inward-angled at the ends. This geometry is presented as the means to move harvested crop through the system.

Core claim

The invention supplies a first nozzle along the first edge of the pan that directs air flow to the trough portion at the bottom, the nozzle comprising vanes that define openings spaced longitudinally, each substantially directed toward the auger discharge, with the vanes slanting progressively more from an orientation substantially perpendicular to the longitudinal direction at the center to an inward angled orientation at an end of the nozzle.

What carries the argument

The air nozzle with vanes that slant progressively from perpendicular at the center to inward angled at the ends, forming openings directed toward the auger discharge.

Load-bearing premise

The geometric arrangement of the vanes and openings will produce the intended directed airflow and improved crop movement in actual use.

What would settle it

Measurement of the actual direction and pattern of air exiting the nozzle openings during harvester operation, or direct comparison of crop flow rates through the pan with and without the described nozzle.

1 . A harvester head, comprising: a gathering assembly; an outlet; a conveying system conveying harvested crop from the gathering assembly to the outlet, the conveying system comprising: an auger having a rotational axis extending along a longitudinal direction and including a center shaft and a helical blade; a pan extending parallel to the rotational axis of the auger, the pan comprising: a first edge at a first side of the rotational axis, a first portion extending from the first edge to beneath the auger, a trough portion extending from the first portion to a second side of the rotational axis, the trough portion defining a lower section with a generally upward extending surface at the second side of the rotational axis, and an auger discharge on the second side of the longitudinal axis; a first nozzle extending along the first edge of the pan, the nozzle directing air flow to the trough portion at a bottom of the pan; wherein the first nozzle comprises vanes defining a plurality of openings spaced longitudinally along the pan, wherein each of the plurality of openings is substantially directed toward the auger discharge, and wherein the vanes slant progressively more from an orientation substantially perpendicular to the longitudinal direction at a center of the first nozzle to an inward angled orientation at an end of the first nozzle.

Referee Report

0 major / 1 minor

Summary. The manuscript is a patent specification for an 'Auger pan air nozzle' in a harvester head. It claims a conveying system with an auger and pan, featuring a first nozzle along the first edge of the pan with vanes defining openings directed toward the auger discharge, where the vanes slant progressively from perpendicular at the center to inward angled at the end.

Significance. The proposed design provides a detailed geometric configuration for directing airflow in the auger pan, which could represent an incremental advancement in harvester technology if it performs as intended. The progressive slanting of the vanes is a specific feature that distinguishes it from standard designs.

minor comments (1)
  1. [Claim 1] The manuscript consists only of the apparatus claim without any figures, detailed description, background, or performance data, which is standard for patent claims but limits the ability to fully assess the invention in a journal context.

Simulated Author's Rebuttal

0 responses · 0 unresolved

We thank the referee for reviewing our patent specification on the Auger pan air nozzle. The report accurately captures the core claim regarding the progressive slanting of the vanes to direct airflow toward the auger discharge. We note the uncertain recommendation and the acknowledgment that the design offers a specific geometric configuration distinguishing it from standard approaches.

Circularity Check

0 steps flagged

No circularity: direct geometric claim with no derivation or fitted inputs

full rationale

The document is a utility patent whose sole load-bearing content is a structural description of a nozzle with progressively slanted vanes. No equations, parameters, predictions, hypotheses, or causal claims exist that could reduce to inputs by construction. The claim is the geometry itself; there are no self-citations, ansatzes, or renamings of known results. This is the most common honest non-finding for a pure mechanical specification.
