Pivotable Support Roller for Mulching Device Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural working devices, such as mulching and mowing devices, lack adjustable components that can adapt to varying conditions like humidity, soil moisture, and plant residue types, leading to inefficiencies and potential damage due to fixed positions and lack of adaptability.
Innovation Solution
The support roller is pivotably mounted and adjustable, allowing it to change positions relative to the working rotor, and the cutting edge can be adjusted mechanically or hydraulically, enabling optimal operation across different conditions, including varying humidity and terrain, while a scraper rail and crop guide plate are designed for efficient material handling and dust reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are arranged in fixed locations on the device, then the device structure is simple and stable, but the device cannot adapt to varying working conditions such as humidity, soil moisture, and plant residue types
Solution Approach 1:
The support roller is designed to be pivotably mounted on the housing, allowing it to dynamically adjust its position between a retracted position and a forward position. This dynamic configuration enables the device to adapt to varying working conditions such as different soil moisture levels, humidity, and plant residue types, while maintaining a relatively simple overall structure.
2Manufacturing precision
If the support roller is positioned close to the working rotor, then cutting quality is improved, but plant material accumulates in the device area inside the housing
Solution Approach 1:
The support roller can be pivoted between a retracted position (reducing accumulation risk) and a forward position (improving cutting quality). This dynamic positioning allows operators to optimize performance based on specific working conditions, such as plant moisture content and residue type, while minimizing harmful accumulation effects.
Solution Approach 2:
By changing the position parameter of the support roller relative to the working rotor, the device can optimize cutting quality while controlling plant material accumulation. The adjustable positioning enables parameter optimization based on working conditions such as soil adhesion capacity and plant matter humidity.
3Object-generated harmful factors
If the support roller is positioned far from the working rotor, then plant material accumulation is reduced, but cutting quality and shredding effectiveness deteriorate
Solution Approach 1:
The pivotable support roller allows dynamic adjustment between retracted and forward positions, enabling operators to optimize the balance between reducing plant material accumulation and maintaining cutting quality based on specific working conditions such as plant moisture and residue type.
4Adaptability or versatility
If movable sub-elements are added to the device housing for adjustment, then adaptability to different working conditions is improved, but device stability is reduced and safety standards are violated
Solution Approach 1:
The pivotable support roller serves multiple functions: it adjusts cutting quality, controls plant material accumulation, and adapts to different working conditions. This multi-functional design provides adaptability while maintaining device stability through a single integrated movable element rather than multiple separate adjustable components.
