Wheel-Mounted Paddle Cleaner for Mud Removal in Agricultural Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural machines face challenges in consistently and effectively removing debris, particularly mud, from their ground engaging components, which can lead to reduced performance and damage due to the sticky nature of accumulated debris, and existing solutions like scraper blades often cause wear and exacerbate the issue.
Innovation Solution
A rotating debris removal component with a paddle wheel mounted proximate to the ground engaging surface, featuring a bearing assembly for rotation and adjustable positioning, which actively removes debris by rotating in the opposite direction of the wheel, utilizing paddles to dynamically clear debris without auxiliary power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed scraper blade is mounted proximate to the ground engaging surface, then debris removal is achieved, but the scraper blade causes wear on the wheel and debris accumulates on the blade itself
Solution Approach 1:
The patent applies the dynamics principle by replacing the static scraper blade with a rotating debris removal component that has multiple paddles. The component rotates about an axis substantially parallel to the wheel axis, creating dynamic motion that removes debris without the continuous friction and wear caused by a fixed blade. The rotation allows the paddles to periodically contact and lift debris off the wheel surface, then release it, preventing both wheel wear and debris accumulation on the cleaning component itself.
2Productivity
If the scraper blade is positioned close to the ground engaging surface, then more debris is removed, but damaging contact with the wheel occurs
Solution Approach 1:
The rotating debris removal component dynamically adjusts its interaction with the wheel through rotation. The paddles approach the wheel surface during rotation, effectively remove debris, then move away during the rotation cycle, preventing continuous contact and potential damage. This dynamic on-off contact pattern allows effective debris removal while protecting the wheel surface from damage.
Solution Approach 2:
The patent implements periodic action through the rotational motion of the debris removal component. The paddles periodically contact the wheel surface to remove debris, then periodically withdraw during rotation. This periodic contact pattern enables effective debris removal while preventing the continuous damaging contact that would occur with a fixed blade positioned close to the wheel.
3Device complexity
If a static scraper blade is used, then the structure is simple, but debris accumulates on the blade and worsens the cleaning effectiveness
Solution Approach 1:
The rotating debris removal component uses dynamic rotation to prevent debris accumulation on the cleaning surfaces. As the paddles rotate, debris is continuously lifted and released, preventing the buildup that occurs with static blades. The rotation creates a self-cleaning effect where debris cannot adhere to the moving paddles in the same way it would on a stationary blade.
Solution Approach 2:
The rotating component maintains continuous useful action by constantly presenting fresh paddle surfaces to the wheel. Unlike a static blade that becomes clogged and requires periodic cleaning or replacement, the rotating component continuously removes debris through its motion, maintaining effective cleaning action throughout operation without interruption or degradation.
