Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjusting the distance between the crop conveyor and the floor plate in agricultural harvesting machines is difficult, which affects the proper transport of collected crop, particularly in the transfer area between the crop pick-up device and the crop conveyor.
Innovation Solution
A receiving device for agricultural harvesting machines incorporates an eccentric body attached to the main frame, allowing for easy adjustment of the distance between the crop conveying device and the floor plate by changing the position of the eccentric body on the main frame, without requiring additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustment mechanisms are used to change the distance between the crop conveyor and the floor plate, then the distance can be adjusted, but the device complexity increases and additional components are required
Solution Approach 1:
The patent uses an eccentric body that can be positioned at different locations on the main frame to change the distance between the crop conveyor and the floor plate. By varying the position parameter of the eccentric body along the longitudinal axis, the distance parameter is adjusted without requiring complex adjustment mechanisms or additional components.
Solution Approach 2:
The patent extracts the adjustment function from a complex mechanical system and simplifies it to a single eccentric body whose position can be changed. This removes the need for additional adjustment components while maintaining the ability to change the distance between the crop conveyor and the floor plate.
2Productivity
If the distance between the crop conveyor and the floor plate is not properly adjusted, then the device structure remains simple, but the crop transport efficiency deteriorates
Solution Approach 1:
The eccentric body position parameter is changed to optimize the distance between the crop conveyor and the floor plate for different crop conditions. This allows the system to adapt to varying swath heights and maintain optimal crop transport efficiency without complex adjustment procedures.
3Adaptability or versatility
If multiple adjustment components are added to enable distance adjustment, then the adjustability improves, but the ease of operation deteriorates due to complex adjustment procedures
Solution Approach 1:
The patent extracts the essential adjustment function and implements it with a single eccentric body whose position can be easily changed. This eliminates the need for multiple adjustment components and complex adjustment procedures while maintaining full adjustability of the distance between the crop conveyor and the floor plate.
