Reversible Kicker Paddle for Road Reclaimers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kicker paddles for road reclaimers are costly and time-consuming to replace due to their integration with the reclaiming drum, leading to extensive downtime during maintenance.
Innovation Solution
A reversible kicker paddle design featuring a symmetric block with a mounting mechanism, allowing for easy detachment, inversion, and reattachment, which extends the life of the paddle and reduces servicing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional kicker paddles are used and welded to flightings, then the flightings and mounting blocks are protected from excessive wear, but the kicker paddles become costly and time-consuming to replace requiring extensive downtime
Solution Approach 1:
The kicker paddle is segmented into a modular design with a separate mounting mechanism that allows independent replacement from the flighting. The paddle body and mounting mechanism are distinct components that can be serviced separately, enabling quick removal and installation without affecting the flighting structure.
Solution Approach 2:
The mounting mechanism is designed to be reusable and removable, allowing the kicker paddle to be easily detached, inverted, and reattached. This enables the recovery and continued use of the mounting mechanism while replacing only the worn paddle portion, reducing waste and replacement costs.
2Ease of operation
If conventional kicker paddles are welded to flightings, then the paddles function to pulverize material and protect components, but the servicing process becomes difficult and time-consuming
Solution Approach 1:
The kicker paddle system is divided into serviceable segments including the paddle body and mounting mechanism. This segmentation allows the mounting mechanism to remain attached to the flighting while only the paddle body needs replacement, simplifying the repair process.
Solution Approach 2:
Instead of welding the paddle to the flighting, the design inverts the attachment approach by using a removable mounting mechanism that facilitates easy detachment and reattachment, making servicing as simple as removing and reinstalling components rather than requiring welding operations.
3Reliability
If kicker paddles are made as sacrificial wear components, then the flightings and mounting blocks are protected, but each paddle must be individually replaced after wear
Solution Approach 1:
The kicker paddle is segmented into a reusable mounting mechanism and a replaceable paddle body. This allows the mounting mechanism to remain on the flighting and be reused, while only the worn paddle body needs replacement, reducing the complexity of the replacement process.
Solution Approach 2:
The mounting mechanism serves multiple functions: it attaches the paddle to the flighting, allows for easy removal and reattachment, and can be reused across multiple paddle replacements. This multi-functionality reduces the overall complexity of the replacement system.

AI summary
A kicker paddle is disclosed for use with a reclaiming drum. The kicker paddle may have a block with a first end and a second end. The kicker paddle may also have a mounting mechanism located between the first and second ends. The kicker paddle may be symmetric relative to a plane passing through the mounting mechanism that is parallel to the first and second ends.
