Internal Scraper for Rolling Basket Plugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baskets used in agricultural tillage implements tend to plug in muddy or moist conditions due to mud accumulation, which disrupts their operation.
Innovation Solution
Incorporating an internal scraper within the basket that is positioned at an acute angle to inhibit soil accumulation by breaking up and expelling debris as the basket rotates, preventing mud from filling the internal volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional basket is used in muddy conditions, then the basket can rotate and engage the ground surface, but mud accumulates in the internal volume causing plugging
Solution Approach 1:
The patent extracts the harmful function of the basket interior by adding an internal scraper that actively removes mud accumulation. The scraper is positioned within the internal volume and extends at an acute angle to scrape the interior surfaces, preventing mud from accumulating and plugging the basket during rotation in muddy conditions.
2Productivity
If the basket rotates to engage the ground surface, then tillage operation is performed, but soil accumulation occurs disrupting operation
Solution Approach 1:
The internal scraper acts as an intermediary element between the basket interior and the rotating motion. It is positioned within the internal volume and oriented at an acute angle to intercept and remove soil accumulation before it can disrupt the basket's rotation and tillage operation.
3Reliability
If the internal scraper is positioned at an acute angle, then soil accumulation is inhibited, but the scraper structure becomes more complex
Solution Approach 1:
The internal scraper is positioned with specific local geometric properties - it extends at an acute angle relative to the basket's longitudinal axis and is located within the internal volume at a specific position. This localized angular configuration creates effective soil scraping action without requiring complex overall structure, as the acute angle itself provides the functional quality needed to inhibit accumulation.

AI summary
A basket rotates about a basket axis with respect to an implement frame when moving in a direction of travel. The basket includes first and second end plates and a plurality of blades extending therebetween. The blades engage the ground surface as the basket rotates and each include a first end and a second end positioned closer to the basket than the first end. The basket defines an internal volume between the first and second end plates and the second ends of the blades. An internal scraper is positioned within the internal volume of the basket such that a portion of the internal scraper extends rearward of a vertical plane extending through the basket axis in the direction of travel and vertically away from the ground surface above a horizontal second plane extending through the basket axis. The internal scraper extends at an acute angle with respect to horizontal.
