Parallel Lift Turret Mount for Spreader Vehicle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spreader vehicles face instability due to a high center of mass when carrying heavy aggregates, as existing designs require raising the hopper, leading to safety concerns, especially when navigating corners or curves.
Innovation Solution
A parallel lift turret mount with a height-adjustable pivoting platform and a throw conveyor turret, featuring a hydraulic lift mechanism, pivot arm, and slope adjustment, allowing the throw conveyor to be vertically and angularly positioned to maintain a lower center of mass and gravity, enabling safe operation and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hopper is raised to align the feed conveyor with the throw conveyor, then the conveyors can be properly aligned for aggregate transfer, but the center of mass of the vehicle rises leading to instability
Solution Approach 1:
The invention applies a dynamic mounting system that allows the throw conveyor to be positioned at variable angles relative to the vehicle chassis. The mount includes adjustable linkages and positioning mechanisms that enable the throw conveyor to be angled upward or downward, allowing proper alignment with the feed conveyor without raising the hopper, thus maintaining vehicle stability while enabling operational flexibility
2Ease of operation
If the feed conveyor is angled upward to accommodate the fixed height of the throw conveyor, then aggregate transfer is enabled, but the center of gravity rises causing safety concerns
Solution Approach 1:
The mount system allows the throw conveyor to be dynamically positioned at different angles, enabling the loading end to be raised or lowered relative to the discharge end. This dynamic adjustment capability allows proper aggregate transfer alignment without requiring the feed conveyor to be permanently angled upward, thereby maintaining a lower center of gravity and improving vehicle safety and stability
3Adaptability or versatility
If the throw conveyor is fixed at a just above grade angle, then stowage during transportation is enabled, but the loading end height is limited requiring the feed conveyor to be lifted
Solution Approach 1:
The invention provides a dynamically adjustable mount that allows the throw conveyor to be positioned at different angles depending on whether the vehicle is in transportation mode or operational mode. During transportation, the conveyor can be stowed at a just above grade angle, and during operation, it can be adjusted to the optimal throwing angle, providing both stowage capability and proper operational alignment without compromising either function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced stability and safety by allowing the throw conveyor to be positioned at various angles and heights, reducing the risk of rollover and enabling operation on steeper grades, while maintaining flexibility for aggregate distribution.
Implementation Method 1
a lift mechanism coupled to the lift plate and the vehicle to vertically adjust the lift plate relative to the vehicle
Implementation Method 2
a pivot arm having a proximal end and a distal end, the proximal end of the pivot arm coupled to the lift plate through a pivot hinge for adjusting angular position of the pivot arm relative to the lift plate

AI summary
A parallel lift turret mount for a vehicle. A lift plate and lift mechanism vertically adjust the turret and pivot arm, which can support and guide rotation of, for example, a throw conveyor. The parallel lift turret mount can be used for processing, moving and slinging aggregate and can be coupled with a hopper or vehicle.
