Solution Overview

Problem

Small square balers have a relatively small capacity, requiring either multiple balers operating simultaneously or converting large bales into small ones, both of which are inefficient and costly.

Innovation Solution

A bale splitting system for agricultural balers that receives a large square bale and splits it into two small square bales using a slanted cutting mechanism, which can be adjusted in position and angle for improved cutting quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple small square balers operate simultaneously to harvest crop material efficiently, then the harvesting capacity increases, but the equipment cost and operational complexity increase

Engineering Contradiction:

Improveharvesting capacityVSAvoidnumber of balers required

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The invention divides a single large bale into two separate small bales using a splitting mechanism. This segmentation allows one baler to produce the output of two balers, effectively reducing the number of equipment units needed while maintaining harvesting capacity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention combines the functions of two separate balers into one by integrating a bale splitting mechanism that divides the output of a single baler into two separate bales, thereby merging the productivity of multiple units into a single operational system.

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If large square bales are produced and converted into small bales later, then the baling capacity increases, but the conversion process is inefficient and expensive

Engineering Contradiction:

Improvebaling capacityVSAvoidconversion efficiency

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The bale splitting mechanism is integrated into the baler system to divide bales into smaller units during the baling process itself, rather than requiring post-production conversion. This preliminary action eliminates the need for separate conversion operations and reduces overall system complexity.

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If a slanted cutting mechanism is used to split bales, then the cutting quality and bale shape improve, but the device complexity increases

Engineering Contradiction:

Improvecutting qualityVSAvoidcutting mechanism structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The cutting mechanism employs a slanted or asymmetric blade orientation rather than a straight perpendicular cut. This asymmetric geometry enables cleaner separation of the bale into two equal halves by following the natural compression lines of the bale material, improving cut quality without requiring complex adjustment mechanisms.

Inventive Principle:

Principle #4Asymmetry

AI summary

An agricultural baler includes a bale chamber having a discharge outlet and a bale splitting system. The bale splitting system includes a cutting mechanism arranged downstream of the discharge outlet and configured to split the bale into two smaller bales. The cutting mechanism is angled forwardly or rearwardly relative to a top wall or a bottom wall of the bale chamber. A bale splitting system that includes two cutting mechanisms angled in opposite directions relative to the bottom wall or the top wall of the bale chamber is also provided.
