Mowing Machine Tumbling Assembly for Blockage-Free Fodder Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mowing machines suffer from fodder accumulation at the bottom of the tumbling bin, leading to blockage of knife holes and reduced cutting efficiency due to the inefficient distribution of fodder within the tumbling mechanism.
Innovation Solution
A tumbling and cutting assembly with a rolling motor, transmission shaft, rolling members, trimming mesh plate, and bevel gears that evenly distribute fodder for uniform cutting, combined with a cutting mechanism using a circular blade and fan blades for efficient fodder collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional tumbling mechanism with rubber strips on a rotating shaft is used, then the structure is simple, but the fodder accumulates at the bottom of the tumbling bin causing blockage of knife holes
Solution Approach 1:
The tumbling mechanism is divided into multiple independent rolling members (cylindrical rollers, blocks, or polygons) distributed across the tumbling bin, each capable of independent rotation. This segmentation allows better distribution of fodder throughout the bin volume, preventing accumulation at the bottom and blocking of knife holes, while maintaining relatively simple individual component structures
Solution Approach 2:
The rolling members are designed to rotate dynamically as fodder is fed into the tumbling bin, creating continuous motion that distributes fodder evenly. The dynamic rotation of multiple rolling members prevents static accumulation zones, ensuring fodder flows continuously to the cutting area without blocking knife holes
2Ease of operation
If rubber strips are arranged on a support rod to tumble fodder, then the mechanism is simple to operate, but the fodder distribution becomes uneven leading to blockage
Solution Approach 1:
The tumbling function is segmented into multiple independent rolling members rather than using a single continuous rubber strip system. This segmentation creates multiple independent zones of fodder movement, ensuring more uniform distribution and preventing blockages that would compromise cutting reliability, while each individual rolling member remains simple in design
Solution Approach 2:
The rolling members act as intermediary elements between the fodder input and the cutting mechanism. These intermediaries actively distribute fodder through their rotation, preventing direct accumulation at the cutting area and ensuring reliable operation of the knife holes without requiring complex control systems
3Device complexity
If fodder accumulates at the bottom of the tumbling bin, then the tumbling mechanism structure remains simple, but the knife holes become blocked affecting cutting
Solution Approach 1:
The rolling members are designed to rotate dynamically in response to fodder input, creating continuous motion that prevents static accumulation at the bottom of the tumbling bin. This dynamic action ensures fodder is continuously distributed toward the cutting area, keeping knife holes clear and maintaining smooth cutting operation without adding significant structural complexity
Solution Approach 2:
The rolling members extend the tumbling action into the vertical dimension by rotating at different heights within the tumbling bin. This multi-level distribution prevents fodder from accumulating only at the bottom, ensuring continuous flow to the cutting area and maintaining operational efficiency with relatively simple mechanical structures
