Catch Roller Soil Sensor Integration for Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soil sensors on agricultural application machines are prone to wear due to contact with the ground and require additional components for attachment, which can lead to clogging issues.
Innovation Solution
Integration of a sensory detection device into a catch roller that rotates over the soil, allowing for soil property detection without additional components and reducing wear by using a rolling contact instead of grinding, with adjustable positioning and various sensor types for comprehensive data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If soil sensors are mounted on a support frame or support arm close to the ground, then soil properties can be detected, but the sensors are highly susceptible to wear and tear from abrasive contact with the ground
Solution Approach 1:
The detection device is integrated into the catch roller itself, merging the soil detection function with the existing rolling component. This eliminates the need for separate sensor mounting structures and protects the sensor by incorporating it into the roller body, where it experiences rolling rather than sliding contact with the ground.
Solution Approach 2:
The patent replaces the traditional mechanical mounting structure (support frame or support arm) with an integrated integration into the catch roller. The sensor is embedded in the roller body or on its surface, transforming the detection system from a separate mechanical assembly to an integrated component that benefits from the roller's motion characteristics.
2Measurement precision
If additional components are added to support the soil sensor, then the sensor can be properly attached and aligned, but the risk of clogging increases
Solution Approach 1:
The detection device is combined with the catch roller into a single integrated unit. The sensor is either embedded in the roller body or mounted on its surface, eliminating the need for separate support arms, mounting brackets, or alignment mechanisms that would otherwise be required to position the sensor correctly.
3Reliability
If the detection device is integrated into the catch roller, then wear is reduced and no additional components are needed, but the detection device must be positioned to avoid ground contact while maintaining detection capability
Solution Approach 1:
The patent applies different functional zones to the catch roller: the circumferential rolling surface contacts the ground for mechanical function, while the detection device is positioned in a different local zone (on the roller body or on the roller surface away from the ground-contact point) to perform sensing without direct ground contact. This local differentiation allows each component to perform its optimal function.
