Solution Overview

Problem

Existing agricultural balers face challenges in optimizing baling capacity while minimizing crop damage, particularly due to a fixed distance between the pickup reel and auger, which is not suitable for various crop conditions, leading to inefficient material feeding and potential damage.

Innovation Solution

A movable pickup reel that adjusts the distance between its rotation axis and the auger's flighting, allowing for optimal alignment based on crop conditions, reducing the risk of damage and stagnant zones through a linkage system and controller-actuated adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the distance between the pickup reel and auger is fixed, then the structure is simple, but the baling capacity cannot be optimized for different crop conditions

Engineering Contradiction:

Improvebaling capacityVSAvoidpickup assembly structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The pickup reel is made movable relative to the auger through a linkage system, allowing the distance between them to be dynamically adjusted based on crop conditions. This transforms the fixed structure into an adjustable one, enabling optimization of material feeding efficiency without permanently complicating the basic design.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The distance parameter between the pickup reel and auger can be changed to optimize performance for different crop types and conditions. By allowing this parameter to vary, the system adapts to different harvesting scenarios while maintaining a relatively simple overall structure through the use of a linkage mechanism.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If the distance between the pickup reel and auger is fixed, then the structure is simple, but crop damage risk increases due to inability to adjust for various crop conditions

Engineering Contradiction:

Improvecrop damageVSAvoidpickup assembly structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The linkage system enables the pickup reel to move dynamically, adjusting the distance to the auger based on crop characteristics. This reduces crop damage by allowing optimal spacing for different crop types while keeping the structural complexity manageable through the use of a mechanical linkage rather than a fully adjustable mechanism.

Inventive Principle:

Principle #15Dynamics

3Productivity

If the pickup reel distance to auger is fixed, then the device is simple to operate, but stagnant zones are created leading to inefficient material flow

Engineering Contradiction:

Improvematerial feeding efficiencyVSAvoidpickup assembly adjustment

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The movable pickup reel eliminates stagnant zones by allowing continuous adjustment of the distance to the auger, improving material flow efficiency. The linkage system provides this functionality while requiring minimal operator intervention, maintaining ease of operation through automatic or simple manual adjustment mechanisms.

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If the pickup reel is fixed, then the structure is simple, but the system cannot adapt to different crop types and conditions

Engineering Contradiction:

Improvecrop condition adaptationVSAvoidpickup reel mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pickup reel is designed to move relative to the auger through a linkage system, providing adaptability to different crop conditions. This dynamic capability is achieved without excessive complexity by using a mechanical linkage that allows adjustment while maintaining structural simplicity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The adjustable pickup reel mechanism serves multiple functions: it adapts to different crop types, optimizes material feeding efficiency, and reduces crop damage risk. This multi-functionality is achieved through a single linkage system that provides versatile adjustment capabilities without requiring multiple separate mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A feeding assembly for an agricultural vehicle includes: a frame; a rotatable auger supported by the frame and including at least one flighting; and a pickup assembly including a rotatable pickup reel and a plurality of tines rotatably carried by the pickup reel about a rotation axis, the tines being configured to pickup and convey crop material to the auger during rotation of the pickup reel. The pickup reel is movable relative to the auger such that movement of the pickup reel adjusts a distance between the rotation axis and the at least one flighting of the auger.
