Harvesting Device Pivotable Pickup and Conveyor for Uneven Ground
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing harvesting devices struggle to completely pick up crops on uneven surfaces and safely transport them, as they are not effectively adapted to compensate for ground unevenness, leading to suboptimal harvest quality.
Innovation Solution
The harvesting device features pivotable receiving members and transverse conveyor devices arranged on the support frame, with pivot axes extending in the longitudinal direction adjacent to the chassis, allowing for ground adaptation without height offsets in the transfer area, and includes limiting devices and a damper for optimal crop transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the pickup elements and cross-conveying devices are made rigid and fixed in position, then the structural stability is improved, but the ability to adapt to uneven ground is worsened
Solution Approach 1:
The patent implements dynamic adaptability by allowing the receiving members and cross-conveying devices to pivot about longitudinal axes. This enables the components to dynamically adjust their position relative to the ground surface while maintaining structural integrity through the pivot connection to the support frame.
2Adaptability or versatility
If the pivot axes are positioned far from the transfer area, then the ground adaptation capability is improved, but the crop flow continuity is worsened due to height offsets
Solution Approach 1:
The patent applies local quality by positioning the pivot axes specifically in the region of the chassis adjacent to the transfer area. This localized positioning ensures that the pivot point is close enough to maintain crop flow continuity while still allowing effective ground adaptation of the receiving and conveying members.
3Adaptability or versatility
If the pickup elements and cross-conveying devices are allowed to pivot freely, then the ground contouring ability is improved, but the crop transport stability is worsened
Solution Approach 1:
The patent employs limiting devices that constrain the pivoting movement parameters of the receiving members and cross-conveying devices. By controlling the range and extent of pivoting motion, the system achieves effective ground contouring while preventing excessive movement that would disrupt crop transport stability.
