Soil Working Frame With Linked Smoothing Roller Lift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil working devices face ergonomic challenges in adjusting the smoothing device to avoid crushing soil clods during operations like hollowing out, requiring manual lifting which is cumbersome, especially with larger models.
Innovation Solution
The smoothing device is adjusted in height relative to the machine frame using the existing height adjustment device of the supporting device, connected via lever arms, allowing it to pivot and be fixed in a raised position, eliminating the need for additional height adjustment mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the smoothing device is lifted from the soil by hand to avoid crushing soil clods, then the soil clods are protected from crushing, but the operation becomes cumbersome and non-ergonomic
Solution Approach 1:
The height adjustment device of the supporting device is made multi-functional by enabling it to adjust both the supporting device height and the smoothing device height through the lever arm mechanism, eliminating the need for a separate adjustment mechanism and reducing operational complexity
Solution Approach 2:
The smoothing device is equipped with self-adjustment capability through the lever arm and height adjustment device, allowing it to be raised automatically without manual lifting, thereby protecting soil clods while maintaining ergonomic operation
2Ease of operation
If an additional height adjustment device is provided for the smoothing device, then the smoothing device height can be adjusted independently, but the device complexity increases
Solution Approach 1:
The existing height adjustment device is designed to perform dual functions: adjusting the supporting device height and adjusting the smoothing device height through the lever arm connection, thereby avoiding additional mechanisms and reducing overall device complexity
Solution Approach 2:
The adjustment mechanisms for the supporting device and smoothing device are merged into a single integrated system using the lever arm as a common element, allowing both components to be adjusted through one control mechanism
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
Facilitates easy and ergonomic adjustment of the smoothing device, preventing soil crushing and enhancing operational efficiency without additional hardware.
Implementation Method 1
The smoothing device can be connected direct or indirect with at least two lever arms to the supporting device and can thus be pivoted relative to the supporting device and the machine frame
Implementation Method 2
The holding device can be actuated, so that the distance between the machine frame and the lever arm connection point can be fixed
