Rolling Basket Internal Scraper for Agricultural Plugging Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rolling baskets for agricultural tillage implements tend to plug in muddy or moist conditions, causing operational inefficiencies and potential equipment damage due to material accumulation.
Innovation Solution
Incorporation of a stationary internal scraper within the rolling basket, which disrupts mud flow and prevents materials from entering the center of the basket, using a stationary blade connected to support arms and bearings, allowing the basket to rotate while keeping the blade stationary to facilitate material dislodgment and discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional rolling basket is used for agricultural tillage, then the basket can rotate and process soil, but the basket tends to plug in muddy or moist conditions causing operational inefficiencies
Solution Approach 1:
The rolling basket is segmented by adding internal scrapers that divide the inner chamber into multiple sections. These scrapers create separate flow paths for muddy or moist materials, preventing accumulation in the center and maintaining continuous rotation and productivity
Solution Approach 2:
Internal scrapers are introduced as intermediary elements within the rolling basket. These scrapers actively disrupt material flow and prevent plugging by scraping the inner chamber walls and redirecting materials toward discharge openings, ensuring reliable operation in muddy conditions
2Reliability
If materials accumulate in the center of the rolling basket, then plugging occurs, but adding structures to prevent this increases device complexity
Solution Approach 1:
The internal scrapers are designed to work dynamically with the rotating basket. The scrapers are positioned to effectively disrupt material flow at different rotational positions, preventing center accumulation without requiring complex adjustable mechanisms or multiple components
Solution Approach 2:
The scrapers create effective flow channels within the basket interior that guide materials toward discharge openings. This simple geometric configuration prevents plugging by maintaining open flow paths without adding complex internal structures or porous materials
3Productivity
If the rolling basket rotates continuously, then productivity is maintained, but large materials can cause equipment damage
Solution Approach 1:
The internal scrapers perform preliminary action by breaking apart large soil clods and materials before they can accumulate and cause plugging. This continuous size reduction prevents harmful materials from building up to damaging levels while maintaining continuous basket rotation and productivity

AI summary
An agricultural implement having a rolling basket which includes a plurality of elongated members arranged in a substantially cylindrical shape. A stationary internal scraper is disposed in the inner chamber of the rolling basket and is adapted for breaking up a material from the inner chamber as the rolling basket is rotated around the major axis of rotation of the rolling basket. The internal scraper extends in an upward direction with respect to the major axis of rotation of the rolling basket with the upper edge of the internal scraper distally spaced away from and above the major axis of rotation of the rolling basket and with the lower edge of the internal scraper distally spaced away from and above the major axis of rotation of the rolling basket. The upper edge of the internal scraper is positioned above the lower edge.
