Haymaking Machine Balance Arm Segmentation for Transport Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing haymaking machines have limited clearance between the rotor and the ground during transport due to a rigid balance arm, which can cause interference and restrict the oblique position of the balance arm.
Innovation Solution
The use of two movable balance arm portions with a horizontal pivot axis allows for a greater distance between the ground and the rotor during transport, while maintaining a substantially horizontal position for effective crop processing, with adjustable stops and protrusions for simplified operation and weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a rigid balance arm is used to support the haymaking machine, then the structure is simple and stable during operation, but the clearance between the rotor and ground during transport is limited
Solution Approach 1:
The rigid balance arm is divided into two separate balance arm portions that can move relative to each other. This segmentation allows the first balance arm portion to pivot relative to the second balance arm portion, enabling increased clearance between the rotor and ground during transport while maintaining structural stability during operation.
Solution Approach 2:
The balance arm structure transitions from a static rigid configuration to a dynamic articulated configuration. The first balance arm portion is mounted to pivot relative to the second balance arm portion, allowing the structure to adapt its geometry between operational and transport states, thereby increasing clearance during transport without compromising operational stability.
2Length of moving object
If the balance arm is positioned obliquely during transport to increase clearance, then the distance between rotor and ground improves, but the wheel may interfere with the rotor
Solution Approach 1:
By dividing the balance arm into two separable portions with relative pivot capability, the system can achieve an oblique transport position that increases clearance while the articulated design prevents the wheel from contacting the rotor, eliminating the interference problem present in rigid structures.
3Ease of operation
If the balance arm portions are freely movable during position transition, then operation simplicity improves, but control precision during positioning may be reduced
Solution Approach 1:
The balance arm portions are designed to be freely movable during the transition from operational to transport position, allowing the mechanism to self-adjust and settle into the correct transport configuration without complex active control systems, thereby maintaining ease of operation while achieving proper positioning.

AI summary
A haymaking machine comprising a frame and a rotatable processing member for crop processing. The processing member is connected with the frame and supported from the ground via a supporting device, which comprises at least one balance arm that is mounted on a substantially horizontal pivot axis and is provided with a wheel at each of its ends. During the crop processing, the wheels bear on the ground, the supporting device further being provided with an element for moving, for transport of the haymaking machine, the balance arm about its pivot axis to an oblique position in which the wheel at one of the ends of the balance arm is located at some distance from the ground. The balance arm comprises two balance arm portions that are movable relative to each other, each balance arm portion having a first end and a second end, the balance arm portions supporting the respective wheel at their first end and being interconnected at their second end.
