Agricultural Machine Chassis Segmented Arm Terrain Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural machines with trailed frames and transverse beams face damage when operating on sloping terrain due to lateral sections pivoting, leading to equipment malfunction and high repair costs.
Innovation Solution
The design incorporates extension arms and intermediate arms with horizontal and vertical articulations, ensuring working members remain stationary relative to the central section, preventing damage from terrain inclines by allowing extension arms to pivot while intermediate arms maintain a fixed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lateral sections are made to pivot around horizontal joints to follow ground slopes, then the machine can adapt to terrain variations, but the working members may move closer to central section equipment causing damage
Solution Approach 1:
The lateral section is divided into two independent arms: an extension arm that pivots to follow terrain and an intermediate arm that remains stationary relative to the central section. This segmentation allows the extension arm to adapt to ground slopes while the intermediate arm maintains a fixed position, preventing damage to working members and central section equipment.
2Adaptability or versatility
If the outer end of lateral section is brought into lower position to follow terrain, then terrain following is improved, but the inclination causes damage to sowing unit and equipment
Solution Approach 1:
The lateral section is divided into two independent arms: an extension arm that pivots to follow terrain and an intermediate arm that remains stationary relative to the central section. This segmentation allows the extension arm to adapt to ground slopes while the intermediate arm maintains a fixed position, preventing damage to working members and central section equipment.
3Productivity
If wide working strip of at least 12 meters is implemented, then productivity is improved, but folding side sections for transport increases device complexity
Solution Approach 1:
The lateral sections are designed as dynamic, foldable structures with vertical articulations that allow them to pivot forward during transport and extend during field operations. This dynamic configuration enables the machine to achieve a wide 12-meter working width for high productivity while automatically reducing to a compact form for road transport compliance.

AI summary
The present invention relates to an agricultural machine (1) for working the soil or for sowing seeds, having a trailed chassis (2) and working members (3) distributed on a transverse beam (4) comprising a central section (5) provided with wheels (6) and two side sections (7) extending on either side of said central section (5) when working, each end of said central section (5) bearing on the ground via a wheel (6). The agricultural machine is characterised in that each side section (7) consists of an extension arm (9) and an intermediate arm (10), said extension arm (9) being linked to said intermediate arm (10) by means of a horizontal hinge (11) having a substantially horizontal axis and directed in the work direction of advance, and in that each intermediate arm (10) is connected to said chassis (2) via a vertical hinge (8) and supports at least one working member (3).
