Double-Shoot Disc Opener Row Unit with Adjustable Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc drills face challenges in reducing the distance between parallel rows of deposited agricultural products without increasing the weight and complexity of the frame structure, which limits the ability to achieve higher crop density and efficient fertilizer diffusion.
Innovation Solution
A double-shoot row unit with two discs and a mechanical linkage assembly that allows for adjustable longitudinal and lateral separation, enabling the formation of two separate trenches and providing flexibility in row spacing without overlapping the discs, combined with independent damping assemblies to prevent excessive motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple rows of row units are added to reduce separation distance, then crop density increases, but weight and frame complexity increase significantly
Solution Approach 1:
The patent combines two disc openers into a single integrated row unit assembly, where the first and second disc openers are mounted on a common frame structure with shared support components. This merging approach allows multiple rows to be produced from one row unit, reducing the overall number of separate row units needed and thereby decreasing frame complexity while maintaining high crop density
Solution Approach 2:
The row unit is designed with multi-functional components that serve multiple purposes. The common frame structure supports both disc openers, and the arrangement allows the same row unit to produce multiple parallel rows. This universality reduces the total number of components needed, lowering overall system complexity while achieving the desired crop density
2Quantity of substance
If multiple rows of row units are added to reduce separation distance, then crop density increases, but the power required to tow the disc drill increases
Solution Approach 1:
By merging multiple disc openers into a single integrated row unit with shared support structures and components, the overall weight of the implement is reduced compared to using separate row units. This weight reduction directly decreases the towing power required while maintaining the ability to produce multiple close-spaced rows for high crop density
3Adaptability or versatility
If the longitudinal separation distance is increased to prevent disc overlap, then the mechanical linkage assembly complexity increases, but this enables flexible row spacing adjustment
Solution Approach 1:
The mechanical linkage assembly incorporates adjustable and movable components that allow the longitudinal separation distance between disc openers to be dynamically changed. This dynamic design enables flexible row spacing adjustment to adapt to different crop density requirements, while the linkage mechanism is designed to manage the complexity through modular and standardized components

AI summary
A double-shoot disc-opener row unit for use with agricultural implements includes two discs that form two separate trenches in a planting surface of a field. The mechanical connection between the two discs provides an adjustable longitudinal separation between the discs to prevent an overlap between the discs from a point view perpendicular to the direction of travel of the row unit. The longitudinal separation may reduce the interference of the flow of soil from one disc from interfering with the formations of trenches by the other disc. An adjustable lateral separation between the discs may also provide for a separation between the trenches produced by the different discs.
