Fill Tray Inlet Assembly for Even Loading of Auxiliary Seed Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The auxiliary storage compartment in agricultural air carts is positioned between primary storage compartments, blocking top access and leading to uneven distribution of particulate material due to side loading, which results in incomplete metering system supply.
Innovation Solution
An inlet assembly with a hopper and a movably coupled fill tray that pivots and engages with a slot system, allowing for lateral loading and ensuring even distribution of particulate material into the auxiliary storage compartment, thereby facilitating uniform supply to the metering system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the auxiliary storage compartment is positioned between the tapered portions of adjacent primary storage compartments to efficiently utilize space, then space utilization is improved, but access to the top of the auxiliary storage compartment is blocked
Solution Approach 1:
The filling assembly is divided into separate components: a hopper that receives particulate material and a fill tray that is movably coupled to the hopper. The fill tray can be independently positioned between a stowage position and a loading position, allowing the loading function to be separated from the storage compartment structure itself.
Solution Approach 2:
The fill tray acts as an intermediary mechanism between the hopper and the auxiliary storage compartment. It provides a movable interface that enables material transfer without requiring direct access to the top of the auxiliary storage compartment, thus resolving the contradiction between compact positioning and loading accessibility.
2Ease of operation
If the auxiliary storage compartment is loaded from the side, then access is enabled, but the particulate material is unevenly distributed within the auxiliary storage compartment
Solution Approach 1:
The fill tray is configured with specific geometric features including a bottom surface, side walls, and a rear wall that work together to control the flow and distribution of particulate material. The tray's structure creates localized flow patterns that ensure even distribution as material is deposited into the auxiliary storage compartment.
Solution Approach 2:
The fill tray moves along a longitudinal axis between stowage and loading positions, adding a dimensional aspect to the loading process. This movement allows the tray to be positioned optimally for material transfer and then retracted, enabling side loading while achieving uniform distribution through controlled material flow along the length of the tray.
3Ease of operation
If a fill tray is movably coupled to allow movement between stowage and loading positions, then loading capability is improved, but device complexity increases due to pivot and slot mechanisms
Solution Approach 1:
The fill tray is designed with dynamic characteristics, being movably coupled to the hopper via a pivot and slot mechanism that allows the tray to move between fixed positions (stowage and loading). This dynamic design enables the system to adapt its configuration based on operational requirements without requiring complex active control systems.
Solution Approach 2:
The pivot and slot mechanism merges multiple functions into a single structural arrangement: it provides rotational movement capability, defines the stowage and loading positions, and enables the engagement/disengagement of locking features. This consolidation reduces the need for separate actuators and control mechanisms for each function.

AI summary
An inlet assembly for a filling assembly of a storage compartment assembly includes a hopper configured to receive particulate material. The inlet assembly also includes a fill tray movably coupled to the hopper and configured to move between a stowage position and a loading position. One of the fill tray or the hopper has a slot, and the other of the fill tray or the hopper has a pivot engaged with the slot. Furthermore, the hopper has a first engagement feature, and the fill tray has a second engagement feature. In addition, the pivot and the slot enable the fill tray to move from the stowage position to a transitional position to align the first and second engagement features, and the pivot and the slot enable the fill tray to move from the transitional position to the loading position to engage the first and second engagement features.
