Hopper Mounting Assembly with Recessed Rod Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size and weight of hoppers in agricultural row units make it difficult to couple them properly to the frame of the row unit while aligning the outlet of the agricultural product meter with the inlet of the conveying system, requiring significant effort and alignment challenges.
Innovation Solution
A mounting assembly with a mounting bracket and support bracket that includes recesses and protrusions to engage rods and facilitate rotation, allowing the hopper to be securely positioned and rotated into alignment with reduced effort, supporting the weight during alignment and blocking rotation to maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the hopper size is increased to store more agricultural product, then the storage capacity is improved, but the weight of the hopper assembly increases making it difficult to couple and align
Solution Approach 1:
The mounting assembly is divided into separate components: a mounting bracket with recesses for positioning, a support bracket with protrusions for bearing weight, and a rod for rotational movement. This segmentation allows each component to perform its specific function independently, making the overall assembly easier to handle despite the hopper's increased weight.
Solution Approach 2:
The rod acts as an intermediary element between the mounting bracket and support bracket, enabling controlled rotation of the hopper assembly from the engagement position to the mounted position. This intermediary mechanism reduces the effort required to reposition the heavy hopper by providing a guided rotational path.
2Quantity of substance
If the hopper assembly is made heavier to increase storage capacity, then the storage capability is improved, but the ease of operation during coupling and alignment deteriorates
Solution Approach 1:
The mounting bracket recesses and support bracket protrusions are pre-configured to guide the hopper assembly into the correct engagement position before final mounting. This preliminary positioning action ensures proper alignment of the agricultural product meter outlet with the conveying system inlet, reducing the operational effort required during installation.
Solution Approach 2:
The mounting assembly transitions from a static connection to a dynamic system that allows rotation about the rod. This dynamic capability enables the hopper to rotate from the engagement position to the mounted position, facilitating easier operation during coupling while maintaining stability in the final position.
3Stability of the object's composition
If the hopper is securely coupled to the frame, then the stability is improved, but the difficulty of alignment during installation increases
Solution Approach 1:
The coupling process is segmented into distinct phases: initial engagement using the mounting bracket recesses for alignment, followed by secure mounting using the support bracket protrusions. This segmentation allows alignment to be performed during the engagement phase before final secure coupling, resolving the contradiction between stability and alignment ease.
Solution Approach 2:
The rod serves as an intermediary that facilitates controlled rotation during the transition from engagement to mounted position. This intermediary mechanism maintains stability during the rotation process while enabling proper alignment, allowing the hopper to be securely coupled after alignment is achieved.
