Seed Drill Coulter Pivotable Retaining Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sowing coulter design has poor accessibility and difficulty in maintaining the seed supply line and associated components, particularly in the end region and outlet openings, leading to challenging blockage removal and assembly processes.
Innovation Solution
The seed supply line and seed catching/pressure roller are arranged on a detachable and pivotable retaining element on the coulter holder, allowing for easy access and exchange, facilitated by a pivot bearing or plug-in connection, enabling the end region to be pivoted into a more accessible area for maintenance and blockage removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seed supply line and seed catching/pressure roller are arranged on a fixed retaining element, then the structure is compact and stable, but the accessibility for maintenance and blockage removal is poor
Solution Approach 1:
The retaining element is divided into a fixed part and a movable part that can be detached from each other. The seed supply line and seed catching/pressure roller are arranged on the movable part, which can be separated from the fixed retaining element to provide access to the seed supply line end region for maintenance and blockage removal.
Solution Approach 2:
The retaining element transitions from a static fixed structure to a dynamic structure with movable and detachable components. The movable part can be pivoted or detached to change the accessibility of the seed supply line, allowing the structure to adapt between operational and maintenance states.
2Ease of manufacture
If the seed supply line is assembled in a fixed position on the coulter, then the assembly is stable, but the assembly and disassembly process is difficult and time-consuming
Solution Approach 1:
The assembly is segmented into modular components: a fixed retaining element and a movable part containing the seed supply line and seed catching/pressure roller. This segmentation allows the movable part to be easily detached and reattached, significantly reducing assembly and disassembly time while maintaining operational stability.
Solution Approach 2:
The seed supply line and associated components are pre-assembled on the movable part of the retaining element before attachment to the coulter. This preliminary assembly simplifies the overall installation process, as the movable part can be attached as a complete unit and quickly removed for maintenance without disassembling individual components in the field.
3Adaptability or versatility
If the holding element with seed supply line is permanently fixed on the coulter holder, then the structural integrity is maintained, but the ability to exchange different furrow opening elements is limited
Solution Approach 1:
The retaining element is segmented into fixed and movable parts, where the movable part can be detached to allow exchange of different furrow opening elements (such as disc coulters, tine coulters, or other seed delivery mechanisms) while maintaining the overall structural integrity of the coulter assembly through the fixed retaining element.
Solution Approach 2:
The fixed retaining element is designed as a universal mounting structure that can accommodate different types of furrow opening elements and seed delivery mechanisms. The standardized interface between the fixed and movable parts of the retaining element allows various configurations to be attached to the same coulter holder, providing multi-functionality and adaptability.

AI summary
The coulter (5) has a furrow opening element arranged at a shoal holder (7). A seed feed pipe (19), front and back attached seed interceptor (22) and/or seed pressure roller (24) are arranged behind the opening element. The seed feed pipe and the seed interceptor and/or seed pressure roller are arranged at a holding element (18) that is arranged at the shoal holder by a swivel bearing in a detachable and path rotatable manner. A deployment channel (20) of the seed feed pipe is detachably attached at the shoal holder.
