Grain Transfer Element Locking by Torque Threshold During Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Harvesting operations face operator errors leading to grain spillage and equipment damage due to incorrect activation of auger folding functions during unloading, resulting in downtime and repair needs.
Innovation Solution
A system with a torque sensor and processor to detect drivetrain torque, comparing it to a threshold to prevent the grain transfer element from moving to a folded position when the torque exceeds the threshold, using a solenoid and hydraulic actuator to control the movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the auger is designed to be foldable for storage, then storage space is reduced, but the risk of accidental folding during grain discharge increases equipment damage and grain spillage
Solution Approach 1:
The system continuously monitors drivetrain torque during auger operation and provides feedback to the control system. When torque exceeds the threshold (indicating grain discharge), the system automatically prevents folding, creating a closed-loop safety mechanism that adapts to real-time operational conditions
Solution Approach 2:
The control system is pre-programmed with torque thresholds and folding prevention logic. Before any damage can occur, the system is ready to automatically prevent folding when torque conditions indicate grain discharge, performing the protective action in advance rather than reacting after damage occurs
2Ease of operation
If manual control of the auger folding is allowed, then operator flexibility is improved, but operator error increases the risk of equipment damage and downtime
Solution Approach 1:
The system performs self-monitoring and self-protection by automatically detecting torque conditions and preventing folding without requiring operator intervention. The control system manages its own safety, eliminating reliance on operator awareness and manual control while maintaining operational flexibility through automated decision-making
3Strength
If the auger folding mechanism is made robust, then structural strength is improved, but the complexity of the drive system increases
Solution Approach 1:
The patent replaces complex mechanical interlocks and additional structural reinforcement with an electronic control system that uses torque sensing and automated control. This substitution reduces mechanical complexity while maintaining or improving safety through electronic monitoring and control
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces grain spillage and equipment damage by ensuring the grain transfer element remains in the unloading position until the drivetrain torque is safe to move, minimizing operational disruptions.
Implementation Method 1
The torque sensor is configured to detect a torque of a drivetrain configured to drive the transfer element
Implementation Method 2
The torque sensor may include a rotational strain gauge
Implementation Method 3
The system may include a hydraulic actuator configured to move the transfer element between the folded position and the unloading position
Data Source
AI summary
A system for directing the movement of a grain transfer element. The system includes a torque sensor and a processor. The torque sensor is configured to detect a torque of a drivetrain configured to drive the transfer element. The processor is configured to compare the detected torque to a torque threshold, and direct the movement of the transfer element between a folded position and an unloading position. The directed movement of the transfer element is based at least in part on a result of the comparison of the detected torque and the torque threshold.
