Coulter Arrangement Lateral Spacing Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural implement coulter arrangements with fixed lateral spacing are prone to obstructions, such as stones, which can lead to operational issues and damage due to the formation of gaps between coulter units.
Innovation Solution
Incorporating a movable coulter unit arrangement with an avoidance device that allows coulter units to adjust their position laterally, temporarily increasing the distance between them to avoid obstructions, and potentially pivoting or translating to spread apart upon contact with disruptive bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If coulter units are arranged with fixed lateral spacing to maintain precise furrow placement, then manufacturing precision and operational consistency are improved, but the risk of obstructions getting trapped between units increases and operational reliability deteriorates
Solution Approach 1:
The coulter units are made dynamically adjustable in their lateral spacing through a positioning device. Each coulter unit can be individually positioned along the support arm to change its lateral distance from other units, allowing the system to adapt between fixed precision mode (normal operation) and dynamic avoidance mode (obstruction present), thus resolving the contradiction between fixed precision and operational reliability
Solution Approach 2:
The lateral spacing parameter between coulter units is made variable through the positioning device. By changing this parameter dynamically based on obstruction detection, the system maintains precise furrow placement under normal conditions while preventing obstruction trapping when needed, thereby resolving the contradiction between manufacturing precision and operational reliability
2Productivity
If coulter units are arranged with smaller lateral spacing to increase productivity, then the number of furrows per unit width increases, but gaps between units become more prone to trapping obstructions and reliability decreases
Solution Approach 1:
The positioning device enables dynamic adjustment of lateral spacing between coulter units. During normal high-productivity operation, units maintain smaller spacing for high furrow density. When obstructions are detected, the system dynamically increases spacing to prevent trapping, thus resolving the contradiction between productivity and operational reliability
Solution Approach 2:
The lateral spacing parameter is optimized to be variable rather than fixed. This allows the system to operate at high productivity with reduced spacing under normal conditions, then switch to reliability mode with increased spacing when obstructions are present, resolving the contradiction between furrow density and operational reliability
3Stability of the object's composition
If multiple coulter units are arranged closely together on a support arm to eliminate lateral forces, then structural stability is improved, but the likelihood of obstructions becoming trapped between units increases and reliability worsens
Solution Approach 1:
The positioning device provides dynamic lateral adjustment capability for each coulter unit on the support arm. This allows the system to maintain close spacing for structural stability during normal operation, while enabling individual units to move laterally to avoid obstructions, thus resolving the contradiction between structural stability and operational reliability
Solution Approach 2:
The support arm structure is segmented with individual positioning mechanisms for each coulter unit. This segmentation allows independent lateral movement of each unit while maintaining overall structural stability, enabling the system to prevent obstruction trapping without compromising structural integrity, thus resolving the contradiction between structural stability and operational reliability

AI summary
Share arrangement (20) for an agricultural implement, comprising at least one support arm (24), which is preferably pivotable in a vertical direction on a frame (10) of the implement, and several share units (21, 22), in particular shares (21A-22B), which can be brought into engagement with a field soil, and which are each coupled to the support arm (24) via at least one retaining arm (21C, 22C), in particular in pairs, and are arranged spaced apart from each other with a defined lateral distance (A).In order to design a share arrangement (20) in such a way as to improve operational safety, in particular of share units (21, 22) arranged in pairs and/or particularly close together, it is provided that at least one share unit (21, 22), in particular a share (21A-22B), is assigned at least one escape device (31, 32) by means of which the share units (21, 22), in particular shares (21A-22B), are arranged to be movable in their position and/or location on the support arm (24), preferably with a variable distance (A), in a substantially lateral direction (R) to each other.
