Position Adjustment Assembly for Agricultural Conveyor Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coordinating the movement of inner and outer arms to align a guide tube with multiple storage compartment openings in air carts is difficult and time-consuming, increasing the duration required for loading agricultural products.
Innovation Solution
A position adjustment assembly that includes an inner arm, an outer arm, and an intermediate link, with a rotation control assembly that adjusts the lateral position of the intermediate link to maintain a constant distance between the outer arm and the air cart, allowing the guide tube to be aligned with each storage compartment via a single actuator, simplifying the alignment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent actuators are used for inner and outer arms, then positioning flexibility is improved, but operation complexity and time increase
Solution Approach 1:
The patent combines the control of inner and outer arms into a single integrated mechanism. The inner arm rotates about the vertical axis while the outer arm simultaneously adjusts the longitudinal position, both controlled by one actuator rather than two independent actuators. This merging reduces operational complexity while maintaining the ability to position the guide tube at multiple locations.
Solution Approach 2:
The single actuator serves multiple functions: it rotates the inner arm about the vertical axis and simultaneously adjusts the longitudinal position of the outer arm. This multi-functional design eliminates the need for separate actuators for each degree of freedom, reducing system complexity while preserving positioning versatility.
2Manufacturing precision
If coordinated movement of inner and outer arms is required, then alignment precision is improved, but time consumption increases
Solution Approach 1:
The patent enables continuous coordinated movement of the inner and outer arms through a single actuating mechanism. As the actuator operates, both arms move simultaneously and continuously to maintain proper alignment between the guide tube and storage compartment openings throughout the positioning process, eliminating the need for sequential adjustment and reducing total positioning time.
Solution Approach 2:
The mechanism is designed so that the outer arm's longitudinal position is pre-adjusted in coordination with the inner arm's rotation. This preliminary coordination ensures that when the guide tube needs to align with a storage compartment opening, both arms are already positioned optimally, reducing the time required for final alignment.
3Measurement precision
If multiple actuators are used for arm adjustment, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges the functions of multiple actuators into a single actuating mechanism that controls both the inner and outer arms. This single mechanism provides sufficient positioning accuracy for aligning the guide tube with storage compartment openings while eliminating the complexity of coordinating multiple independent actuators.

AI summary
A position adjustment assembly for an agricultural conveyor includes an inner arm having a first end configured to rotatably couple to an agricultural storage system, and an outer arm having a first end, a second end, and a pivot positioned between the first end and the second end. A second end of the inner arm is rotatably coupled to the outer arm at the pivot, and the agricultural conveyor is configured to rotatably couple to the second end of the outer arm. The position adjustment assembly also includes a rotation control assembly configured to couple to the agricultural storage system, and an intermediate link having a first end engaged with the rotation control assembly, and a second end rotatably coupled to the first end of the outer arm.
