Threshing Power Adjustment for Crop Condition Variations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural machines face challenges in efficiently processing harvested crops due to varying crop conditions such as moisture and toughness levels, which affect the power requirements of their subsystems like threshing and crop debris routing assemblies, leading to inefficiencies and potential damage.
Innovation Solution
The implementation of a method and system that uses sensors to measure performance parameters like torque and force, and machine parameters like feed rate and rotational speed, to determine crop conditions and adjust power requirements dynamically through a controller, ensuring optimal processing and reducing wear and tear.

Engineering Contradiction Analysis
1Productivity
If the agricultural machine processes harvested crop with threshing rotor and chopper rotor at high power, then processing efficiency is improved, but energy consumption increases and mechanical stress on components increases
Solution Approach 1:
The system dynamically adjusts the power delivered to the threshing rotor and chopper rotor based on real-time crop condition detection. Sensors monitor crop moisture and toughness levels, and the controller modulates power delivery accordingly, allowing the machine to operate at high power when needed (improving processing efficiency) while consuming less energy during normal operating conditions.
Solution Approach 2:
The system changes the power parameter delivered to the rotors based on detected crop conditions. When crops are detected to have higher toughness or moisture levels requiring more intensive processing, the power parameter is increased; otherwise, power is reduced, thereby resolving the contradiction between processing efficiency and energy consumption.
2Productivity
If the agricultural machine processes harvested crop with threshing rotor and chopper rotor, then crop processing is achieved, but mechanical stress and wear on components increases
Solution Approach 1:
The system monitors crop toughness levels and adjusts the power parameter delivered to the threshing and chopper rotors accordingly. When crops are detected to be softer or more brittle, the power parameter is reduced, thereby minimizing mechanical stress and wear on the rotor components while still achieving effective crop processing.
3Productivity
If sensors and controllers are added to measure and adjust power parameters, then processing efficiency and reliability are improved, but device complexity increases
Solution Approach 1:
The system employs sensors to detect crop conditions (moisture, toughness) and feeds this information back to the controller, which then adjusts the power parameter delivered to the rotors. This feedback loop enables the system to automatically optimize processing efficiency and reduce mechanical stress without requiring complex manual intervention, as the controller autonomously modulates power based on real-time sensor data.

AI summary
An agricultural machine includes a threshing assembly, a crop debris routing assembly, and a controller configured to identify a relationship between a performance parameter that is associated with the threshing assembly or the crop debris routing assembly and one or more performance-modifying parameters. The one or more performance-modifying parameters include a machine parameter, a crop condition, or a chop quality of harvested crop. The controller is configured to adjust at least one machine parameter to change an amount of power required by at least one of the threshing assembly and the crop debris routing assembly.
