Solution Overview

Problem

Conventional conveying devices in harvesting machines, such as balers, face issues with overload and blockages due to uneven crop distribution, leading to interruptions and differences in density or compression, as they cannot react partially across the width of the rotor, affecting the pressing process.

Innovation Solution

The conveyor channel floor is divided into multiple segments that can be adjusted radially and independently using sensors and actuators to manage load distribution, allowing for precise control of the crop flow without affecting the entire width of the rotor, thereby optimizing the pressing process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the conveying channel floor is lowered to prevent overload and blockages, then the reliability of crop flow is improved, but the uniformity of crop density and compression deteriorates because the entire width of the feed rotor is affected

Engineering Contradiction:
Improvereliability of crop flowVSAvoiduniformity of crop density
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The conveying channel floor is divided into multiple independently adjustable floor segments along the axis of rotation. When overload is detected in a specific radial section, only the corresponding floor segment is lowered to increase the channel cross-section and reduce load, while other segments remain in position. This segmentation allows localized response to overload conditions, preventing uniform lowering that would disrupt crop flow uniformity across the entire rotor width.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the conveying channel floor is lowered beyond a certain level to prevent blockages, then the reliability is improved, but the productivity deteriorates due to interruption or delay of the pressing process

Engineering Contradiction:
Improveprevention of blockagesVSAvoidpressing process continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By segmenting the floor into independent adjustable sections, the system can lower only the specific segment where blockage risk is detected, rather than lowering the entire floor. This localized adjustment prevents blockages in the affected area while maintaining normal operation in other sections, thus avoiding interruption or delay of the overall pressing process and preserving productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies partial action by lowering only the necessary portion of the floor (specific segments) rather than the entire floor. This partial adjustment is sufficient to prevent blockages in the overloaded section while avoiding excessive lowering that would disrupt the pressing process in other sections, thereby maintaining productivity.

Inventive Principle:
Principle #16Partial or excessive action

3Force

If the conveying channel cross section is increased by lowering the floor, then the load on the conveying rotor is reduced, but the crop flow uniformity deteriorates because the adjustment affects the entire width

Engineering Contradiction:
Improveload on conveying rotorVSAvoidcrop flow uniformity
Core Design Contradiction:
ForceVSStability of the object's composition

Solution Approach 1:

The floor is divided into multiple independent segments that can be adjusted individually. When overload is detected in a specific radial section, only the corresponding segment is lowered to increase the channel cross-section and reduce load in that area. This localized adjustment reduces the load on the conveying rotor without affecting the uniformity of crop flow across the entire width, as other segments remain in their original positions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies local quality by making adjustments only in the specific radial sections where overload is detected, rather than uniformly across the entire width. Each floor segment can be independently lowered to create local variations in channel cross-section that match the local load distribution, thereby reducing load where needed while preserving crop flow uniformity in other areas.

Inventive Principle:
Principle #3Local quality

AI summary

A conveying device (22) for harvested crops is presented. The conveying device (22) comprises a conveying rotor (26), a conveying channel (36), and a conveying channel floor (28), wherein the conveying rotor (26) and the conveying channel floor (28) are arranged at variable distances from each other and at least partially define the conveying channel (26). The conveying channel floor (28) can be adjusted radially relative to the axis of rotation (45) of the conveying rotor (26) by at least one adjusting device (30). To improve the quality of the crop flow, it is proposed that the conveying channel floor (28) be subdivided in the direction of the axis of rotation into at least two floor segments (28', 28", 28''), each of which can be adjusted independently relative to the conveying rotor (26) by an adjusting device (30). Furthermore, a baler (10) with a conveying device (22) is proposed.
