Agricultural Boom Mounting Assembly with Adjustable Roller Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boom mounting assemblies for agricultural machines lack stability and performance, particularly when operating on inclined terrain, as they fail to effectively balance the boom across varying ground conditions.
Innovation Solution
A boom mounting assembly featuring a primary frame, a boom support frame that pivots in a transverse plane, and a roller assembly with sub-frame members and roller members that allow for adjustable positioning and balancing, utilizing rollers made of materials like thermoplastic polyurethane or nylon, and an actuator to adjust support sections relative to the pivot point based on ground inclination measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the boom support frame is suspended from the primary frame to allow pivoting movement, then the boom can balance in desired positions including non-horizontal positions on inclined terrain, but the stability and performance of the assembly deteriorates due to insufficient control over pitch and yaw movements
Solution Approach 1:
The boom support frame is designed with dynamic movement capabilities, allowing it to pivot in a transverse plane around a longitudinal axis of rotation. This dynamic configuration enables the boom to adapt to different terrain inclinations and balance in desired positions, including non-horizontal positions, while maintaining operational stability through controlled movement rather than fixed positioning.
Solution Approach 2:
The system employs dampers that can be adjusted to control the damping characteristics of pitch and asymmetrical yaw movements. By changing the damping parameters, the system optimizes both the adaptability of the boom to different terrain conditions and the stability of the assembly during operation, resolving the contradiction between movement freedom and stability.
2Reliability
If dampers are positioned spaced from the transverse center of the assembly, then pitch and asymmetrical yaw movements can be controlled, but the device complexity increases
Solution Approach 1:
The damping function is segmented into separate dampers positioned at specific locations spaced from the transverse center of the assembly. This segmentation allows independent control of pitch and asymmetrical yaw movements, enabling precise movement control while maintaining a relatively simple overall structure by using discrete, localized damping elements rather than a complex distributed system.
3Ease of operation
If the running surface of the roller member rests against the boom support frame or boom section, then friction is reduced and ease of operation is improved, but the roller member may detach under certain operating conditions
Solution Approach 1:
The roller member is designed with a rotatable sub-frame member that allows the roller to dynamically adjust its position and orientation. This dynamic configuration enables the running surface to maintain contact with the boom support frame or boom section during normal operation, reducing friction and improving ease of operation, while the rotatable capability allows the roller to accommodate variations in load and position that prevent detachment.

Function Achieved in This Case
The assembly provides improved stability and performance by allowing the boom to balance dynamically across different terrain inclinations, reducing friction and maintaining optimal boom position through adjustable support sections and roller surfaces, enhancing operational efficiency and preventing damage.
