Sliding H-Beam Tool Attachment Structure for Adjustable Row Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural machinery lacks a versatile and efficient structure for attaching tools, such as seeding elements and fertilizer buriers, that allows easy adjustment of spacing and simplifies the transition between working and transport configurations without releasing attachment means.
Innovation Solution
A tool attachment structure with two support means, each having two contact surfaces oriented at intersecting planes, allows sliding and centering of tools on a telescopic beam, reducing material and assembly costs while enabling easy spacing adjustment and balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single contact surface attachment structure is used, then the device complexity is reduced, but the tool stability and centering capability deteriorate
Solution Approach 1:
The attachment structure is segmented into two separate support means (first support means and second support means) instead of using a single contact surface. Each support means provides a distinct contact point on the beam, dividing the attachment function into multiple stable contact points that collectively enhance tool stability while maintaining relatively simple individual components.
Solution Approach 2:
Each support means is designed with specific local characteristics - the first support means contacts the beam at a first location while the second support means contacts at a second location. This local differentiation in contact positions and orientations creates stable geometric relationships that center the tool on the beam without requiring complex overall structure.
2Length of moving object
If tools are mounted with overhang on the beam, then the working reach is increased, but the beam structural requirements and material usage increase
Solution Approach 1:
The support means are positioned and oriented in advance during beam design to optimize the load distribution. By pre-configuring the contact locations and orientations of the support means, the beam can be designed with minimal necessary material to handle the overhang loads, rather than requiring excessive material to accommodate arbitrary mounting configurations.
3Stability of the object's composition
If fixed attachment means are used, then the tool position is stable, but the ability to adjust row spacing deteriorates
Solution Approach 1:
The attachment structure transitions from a static fixed connection to a dynamic adjustable system. The support means are designed to allow relative movement or repositioning along the beam while maintaining stable contact during operation. This enables the tool position to be adjusted for different row spacings while preserving stability during each working configuration.

AI summary
The invention relates to a tool attachment structure for a beam (10) of an agricultural machine (9), comprising: - a first and a second support means (30';30), - at least one tool attachment means (40, 40'), - at least one support (50, 50') for the first support means (30;30'), - at least one fastening means (60) for holding the first and second support means (30';30) against the beam (10), and for mounting the tool attachment structure (20) on said beam (10), characterized in that: the first support means (30;30') has two contact surfaces (31, 32; 31', 32') designed to come into contact with a respective support surface (101, 102; 101', 102') of the beam (10) of the agricultural machine, the first and second contact surfaces (31) each being oriented according to a respective guiding plane (P1; P1'; P2; P2'), intersecting one with the other.
