Residue Spreader Monitoring for Even Combine Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural combine systems face challenges in efficiently and evenly distributing residue material, as manual adjustments are complex and time-consuming, and existing automated systems are not comprehensive in ensuring uniform distribution and avoiding residue spread into standing crops.
Innovation Solution
A system comprising first and second sensors with two-dimensional sensing regions and controllers to monitor and control the distribution of residue material, allowing for real-time adjustments to the spreader tool's operation to maintain even distribution within the machine's width and avoid standing crops, using LIDAR sensors and a control system to output control signals for steering mechanisms and rotor speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual observation and adjustment of the spreader tool is used, then the operator can control residue distribution, but the process becomes complex and time-consuming especially when operating conditions vary
Solution Approach 1:
The system enables self-service operation by automatically monitoring residue distribution through sensors and adjusting spreader tool operation without requiring continuous manual observation and adjustment by the operator
Solution Approach 2:
The system implements feedback control by using sensors to detect residue distribution patterns and automatically adjusting spreader tool operation based on the detected distribution, creating a closed-loop control system
2Extent of automation
If sensors are used to monitor residue distribution in real time, then automated control can be implemented, but the system complexity increases
Solution Approach 1:
The system achieves multi-functionality by using a single sensor arrangement that simultaneously monitors residue distribution across multiple zones and provides comprehensive control data for the spreader tool operation
Solution Approach 2:
The system merges the sensing and control functions into an integrated arrangement where the sensor data directly informs spreader tool adjustments, combining multiple functions into a unified system

AI summary
Systems and methods for monitoring the distribution of residue material from a spreader tool of an agricultural machine including a first sensor with a sensing region defining a first sensing boundary corresponding to a first direction with respect to the agricultural machine, a second sensor with a sensing region defining a second sensing boundary corresponding to a second direction with respect to the agricultural machine, and using the sensing data from the first and second sensors to determine a distribution of residue material associated with the spreader tool. One or more systems of the agricultural machine are then controlled based on the determined distribution.
