Front Loader Stand With Swing Shaft And Engagement Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stands for front loaders mounted on work vehicles, such as tractors, require cumbersome fixing pin operations to switch between supporting and storage attitudes, making them difficult to use efficiently.
Innovation Solution
A stand configuration for front loaders that includes a main-body portion with a swing shaft, a grounding portion, and an engagement lever, allowing for easy switching between storage and supporting positions without the need for fixing pins, utilizing a biasing member to maintain engagement with the boom and regulate swinging range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixing pin is used to hold the stand in supporting or storage attitude, then the stand can be securely fixed in each attitude, but the work of switching attitudes becomes cumbersome
Solution Approach 1:
The stand is designed to automatically engage and disengage from the boom using spring-loaded latching mechanisms. The weighting portion and engagement lever system allow the stand to self-lock in the supporting position and self-release when needed, eliminating the need for manual fixing pin operations while maintaining secure fixation
Solution Approach 2:
An engagement lever acts as an intermediary mechanism between the operator and the stand positioning system. By manipulating the engagement lever, the operator can easily switch the stand between attitudes without directly handling fixing pins, as the lever controls the latching and unlatching of the stand to the boom
2Reliability
If a fixing pin is required for attitude switching, then the stand can be held in position, but the complexity of the device increases
Solution Approach 1:
The fixing functionality is merged into the boom structure itself through integrated latching mechanisms. The weighting portion, engagement lever, and latching features are combined into a unified system that is part of the boom assembly, eliminating the need for separate fixing pins and reducing overall device complexity
Solution Approach 2:
The separate fixing pin component is extracted and replaced by built-in latching mechanisms that are integral to the boom and stand assembly. This extraction simplifies the system by removing unnecessary components while maintaining the essential holding capability through the engagement lever and latching features
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
Enables the front loader to be easily and efficiently switched between storage and supporting positions, improving operational ease and reducing the risk of misplacement or loss of fixing components.
Implementation Method 1
a biasing member (260) that biases the engagement lever (250) in a direction in which the hooked end (253) engages with the weighting portion (243)
Implementation Method 2
a swing shaft (214) that connects the main-body portion (210) to the boom (300) in a swingable manner
