Mulcher Feed System with Adjustable Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current forestry clearing machinery lacks an efficient and controlled method for mulching and chipping vegetation, particularly for processing large diameter logs, which results in inconsistent mulch product sizes and safety concerns during operation.
Innovation Solution
A mulching and chipping attachment equipped with a cutting disk, guide chute, and feed system that includes rollers and a reactionary member, allowing for controlled feeding of logs into the cutting disk, enabling safe and efficient processing of large diameter logs into consistently sized mulch products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If logs are fed manually or without control into the cutting disk, then the processing speed may be increased, but safety concerns arise and the mulch product size becomes inconsistent
Solution Approach 1:
The patent introduces a feed system with rollers and a reactionary member as an intermediary between the operator and the cutting disk. This intermediary mechanism controllably feeds logs into the cutting disk at a controlled rate and angle, eliminating the need for manual feeding while maintaining safety and product consistency. The feed system acts as a mediator that transforms uncontrolled manual feeding into controlled mechanical feeding.
2Device complexity
If a simple cutting disk design is used, then the device complexity is reduced, but the ability to process large diameter logs efficiently is compromised
Solution Approach 1:
The patent segments the log processing function into distinct components: a guide chute for positioning, a feed system with rollers for controlled advancement, a reactionary member for securing the log, and the cutting disk with cutting elements. This segmentation allows each component to perform its specific function efficiently, enabling the processing of large diameter logs while maintaining manageable overall system complexity.
Solution Approach 2:
The feed system incorporates movable rollers and a reactionary member that can dynamically adjust to accommodate logs of varying sizes. The rollers are positioned to grasp and feed logs of different diameters, and the reactionary member can react against logs of various sizes to secure them for cutting. This dynamic adaptability enables efficient processing of large diameter logs without requiring a completely different system design.
3Productivity
If logs are fed at high speed into the cutting disk, then productivity increases, but the mulch product size consistency deteriorates
Solution Approach 1:
The feed system incorporates a reactionary member that provides feedback by reacting against the log being fed. This reaction force ensures that logs are fed at a controlled rate and angle, preventing excessive speed that would compromise mulch product consistency. The reactionary member adjusts its position and force based on the log characteristics, providing real-time feedback control to maintain consistent cutting conditions while achieving high productivity.

AI summary
A mulching and chipping attachment includes a deck having a top plate. A cutting disk is attached to the deck. The top plate includes an opening that exposes a portion of the cutting disk. A guide chute is attached to the deck, and is disposed over the opening. The guide chute includes a feed system. The feed system includes a first roller, and a reactionary member operable to react against the first roller to secure a log therebetween. The first roller and the reactionary member cooperate together to grasp and controllably feed the log through the opening. The first roller or the reactionary member may be moveable relative to the other, to adjust a throat distance therebetween. An anvil may be disposed at a rearward edge of the opening, and extend downward to define a chip cutting height between the anvil and the cutting disk.
