Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seed drills face challenges in simplifying the lateral positioning of rotary tools, requiring complex assembly processes and time-consuming adjustments, which affect the accuracy and efficiency of seed placement.
Innovation Solution
A seeder design with rotary tools arranged in two rows on separate beams, each with independent ground-following capabilities and a compact mounting structure, utilizing a console with identical arms to simplify tool positioning and allow for independent mounting, reducing assembly time and enhancing precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If rotary tools are mounted individually on crossbeams with complex support structures, then the positioning flexibility is improved, but the assembly time and device complexity increase significantly
Solution Approach 1:
The patent combines multiple rotary tools (opening discs and seeding discs) onto a single console structure, where tools that were previously mounted separately on different crossbeams are now integrated. This merging reduces the number of individual mounting operations and simplifies the overall assembly process while maintaining precise lateral positioning through the unified console design.
Solution Approach 2:
The console is pre-configured with all necessary mounting points and positioning features before field assembly. The lateral positioning of rotary tools is predetermined by the console's fixed geometry, eliminating the need for time-consuming individual adjustments during assembly. This preliminary preparation of the mounting structure significantly reduces setup time.
2Adaptability or versatility
If rotary tools are mounted on complex parallelogram suspension structures, then the ground contour following capability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent segments the ground contour following function from the lateral positioning function. The console handles precise lateral positioning with fixed geometry, while separate ground-following mechanisms (such as individual tool depth control or frame suspension) handle terrain adaptation. This segmentation allows each subsystem to be optimized independently, reducing overall complexity.
3Reliability
If rotary tools are arranged in two rows on separate beams, then the clogging risk is reduced, but the lateral positioning accuracy and assembly precision are compromised
Solution Approach 1:
The patent merges the two-row arrangement advantage with precise lateral positioning by mounting both rows of rotary tools on a single rigid console. The console's fixed geometry ensures accurate lateral spacing between tools in both rows, while the two-row configuration itself maintains clogging resistance by distributing tools across different lateral positions. This integration preserves both reliability and precision.

AI summary
The present invention relates to a seed drill (1) comprising a frame (3) and rotating tools (2) regularly distributed and arranged in two rows on a respective beam (8, 9) fixed to the frame (3). The seed drill is notable in that a bracket (20) carries two rotating tools (2), each connected to the bracket (20) by means of a respective arm (21), and the rotating tools (2) extend substantially below the bracket (20).
