Coaxial Windrowing Assemblies for Compact Side-Delivery Rake Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side-delivery rakes face challenges in maneuverability and transportation due to their size discrepancy between working and transport configurations, leading to increased costs and inefficiencies, and difficulties in navigating unstraight paths without proper forage collection.
Innovation Solution
A side-delivery rake with coaxial windrowing assemblies and a compact frame design, featuring a longitudinal bar, bridge-type supporting structure, and three-point hitch connections, allowing for rotation and adjustment to maintain a wide working spread while being easily transportable, utilizing a single hinge pin for compactness and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the side-delivery rake is designed with a large working spread to process a given area efficiently, then productivity is improved, but the device size in road transport configuration increases requiring special transport arrangements
Solution Approach 1:
The windrowing assemblies are designed to be rotatable between working and transport positions. In the working position, the assemblies are lowered and spread wide to maximize processing area. In the transport position, the assemblies are rotated upward and inward, reducing the overall width and length to fit standard transport restrictions without requiring special arrangements
Solution Approach 2:
The invention utilizes vertical rotation of the windrowing assemblies to achieve compactness in the horizontal transport dimension. By rotating the assemblies upward and inward about vertical axes, the device reduces its horizontal footprint while maintaining its processing capability when in the working position
2Stability of the object's composition
If the distance between windrowing assemblies is increased to provide structural support, then stability is improved, but maneuverability deteriorates when navigating curved paths
Solution Approach 1:
The windrowing assemblies are connected to the frame via rotatable connections that allow dynamic adjustment during operation. When navigating curved paths, the assemblies can rotate independently to follow the frame's motion, maintaining coordinated operation and proper forage collection even on tight curves
Solution Approach 2:
The invention allows the operational parameters of the windrowing assemblies (such as their angular position and spacing) to change dynamically based on the operating conditions. During curved path navigation, the assemblies adjust their positions to maintain optimal performance while reducing the effective radius constraint
