Residue Splitter Flow Guide for Even Crop Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Horizontal crop residue spreaders often result in uneven distribution of crop residue across a field due to varying terrain and environmental conditions, leading to issues like clumping, uneven field insulation, and habitat creation for rodents and insects.
Innovation Solution
A residue splitter apparatus with a flow guide element and adjustable mechanism that positions itself between the spreader paddles to redirect crop residue flow, ensuring a more even distribution by extending rearwardly and sidewardly, allowing for lateral expanse adjustment to compensate for changing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If horizontal spreader paddles are used to distribute crop residue, then residue can be spread across the field, but uneven distribution occurs with heavier concentration near the center and lighter concentration toward the sides
Solution Approach 1:
A flow guide element is introduced as an intermediary component between the spreader paddles and the crop residue flow. This flow guide element redirects the residue trajectory, taking material from the center region and directing it toward the lateral edges, thereby mediating the distribution process to achieve more uniform coverage across the field swath.
Solution Approach 2:
The flow guide element extends laterally beyond the spreader paddles in the sideward direction, adding a dimensional component to the residue distribution that was not present with the paddles alone. This lateral extension creates additional flow paths that carry residue from the center toward the edges, effectively utilizing spatial dimension to improve distribution uniformity.
2Adaptability or versatility
If fixed spreader configuration is used, then device complexity is low, but adaptability to varying terrain and environmental conditions is insufficient
Solution Approach 1:
The flow guide element is designed with adjustable components that allow dynamic reconfiguration of the residue flow paths. The ability to modify the flow guide's position or angle enables adaptation to varying terrain slopes, wind conditions, and field widths, transforming a static device into a dynamically adjustable system that responds to environmental conditions.
Solution Approach 2:
The adjustment mechanism allows changing of critical parameters such as the flow guide element's lateral position, angle of inclination, or extension distance. By varying these parameters, the system can optimize residue distribution for different field conditions, soil types, and environmental factors without requiring complete system redesign.
3Stability of the object's composition
If residue is distributed without flow guidance, then device complexity is minimal, but clumping and uneven insulation occur
Solution Approach 1:
The flow guide element is segmented into multiple functional zones: a front edge portion that intercepts central residue flow, side flow surfaces that direct lateral distribution, and rear portions that manage residual material. This segmentation allows each zone to address specific distribution problems, breaking down the complex distribution task into manageable functional segments that work together to eliminate clumping.

AI summary
A residue splitter apparatus for use with a horizontal spreader assembly that employs a pair of spreader paddles disposed side-by-side to rotate about respective generally vertical axes for controlling the spread width distribution of crop residue on and over a field, and the method of use thereof, including a flow guide element located generally intermediate to the spreader paddles of the horizontal spreader assembly with crop residue flow surfaces that extend rearwardly from a front edge portion of the flow guide element and sidewardly to free end portions generally aft of at least portions of the spreader paddles to receive and direct the flow of crop residue from such spreader paddles. Preferably, the flow guide element is laterally expandable to permit the flow of crop residue from the spreader paddles to be adjustably varied to effect a desired pattern of crop residue flow from the spreader paddles, for instance, so as to better and more evenly distribute the flow side-to-side over a swath of an agricultural field from which the crop was harvested.
