Position Adjustment Assembly for Agricultural Conveyor
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, where the inner arm is rotatably coupled to the outer arm at a pivot, and the intermediate link drives the outer arm to rotate, maintaining a constant lateral distance from the air cart, allowing the guide tube to align with each storage compartment opening via a single actuator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If independent actuating cylinders are used for inner and outer arms, then the conveyor can be positioned, but the coordination of movement becomes difficult and time-consuming
Solution Approach 1:
The patent combines the control of inner and outer arms into a single integrated mechanism. The inner arm and outer arm are coupled such that actuating the inner arm automatically coordinates the movement of the outer arm through mechanical linkage, eliminating the need for separate actuating cylinders and their complex coordination.
Solution Approach 2:
The patent introduces an intermediate mechanism (the coupled arm structure) that mediates between the actuator on the inner arm and the position of the outer arm. This intermediate mechanical linkage automatically translates inner arm movement into coordinated outer arm movement, solving the coordination problem without requiring complex control systems.
2Quantity of substance
If multiple storage compartments are added to the air cart, then product storage capacity increases, but the time to align guide tube with each opening increases
Solution Approach 1:
The patent implements a dynamic positioning system where the conveyor and its guide tube can be rapidly repositioned along the longitudinal axis. The coupled arm mechanism enables smooth, continuous adjustment of the guide tube position to align with different storage compartment openings, reducing alignment time despite having multiple compartments.
3Adaptability or versatility
If the conveyor is made adjustable along the longitudinal axis, then alignment with storage compartments is improved, but the structural complexity increases
Solution Approach 1:
The coupled arm mechanism serves multiple functions simultaneously: it provides structural support for the conveyor, enables longitudinal positioning adjustment, and coordinates the movement of both inner and outer arms. This multi-functionality reduces the need for separate adjustment mechanisms, thereby limiting the increase in structural complexity.

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 at a first location. The position adjustment assembly also includes 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. In addition, the position adjustment assembly includes an intermediate link having a first end configured to rotatably couple to the agricultural storage system at a second location, longitudinally offset from the first location. A second end of the intermediate link is rotatably coupled to the first end of the outer arm.
