Soil Cultivation Device Lateral Pull Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil cultivation devices face challenges in maintaining central alignment behind a towing vehicle due to uneven lateral forces acting on transverse rows of rotatable disk elements, requiring complex and time-consuming adjustments with changing ground conditions.
Innovation Solution
The implementation of a height-adjustable mechanism using hydraulic or mechanical adjusting devices allows for simple adjustment of the rear transverse row relative to the front transverse row, with optional automatic control via sensors or angle measuring devices to equalize lateral forces and prevent lateral pull.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the disk elements in the front and rear transverse rows are set to engage the soil with the same depth, then the structure is simple, but lateral forces become unbalanced causing the tillage implement to pull to one side
Solution Approach 1:
The patent introduces height-adjustable mechanisms that allow the rear transverse row to be dynamically adjusted relative to the front transverse row. This enables the system to adapt to varying soil conditions and maintain central alignment by balancing lateral forces, transforming a static symmetric structure into a dynamically adjustable asymmetric configuration when needed.
Solution Approach 2:
The patent applies different engagement depths to the front and rear transverse rows through localized height adjustment mechanisms. By adjusting only the rear row's height relative to the front row, the system creates local asymmetry in the engagement configuration to balance lateral forces, rather than requiring uniform adjustment across all components.
2Ease of operation
If individual adjusting elements are arranged on crossbeams to adjust disk element heights, then lateral pull can be eliminated, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
The patent employs a unified height-adjustable mechanism that serves multiple functions: it adjusts the rear transverse row's height, controls the engagement depth differential between front and rear rows, and balances lateral forces. This multi-functional approach consolidates what would otherwise require multiple separate adjustment operations into a single integrated system.
Solution Approach 2:
The patent combines the height adjustment function and lateral force balancing function into a single integrated mechanism. By merging these functions, the system eliminates the need for separate adjustment operations for each function, reducing the overall complexity and time required for adjustments.
3Productivity
If the tillage implement position shifts laterally due to unbalanced forces, then no adjustment is needed, but the implement is no longer centrally positioned behind the towing vehicle
Solution Approach 1:
The patent incorporates angle measuring devices that detect the orientation and angular position of the tillage implement relative to the towing vehicle. This feedback mechanism monitors lateral position shifts and provides information to the control system, enabling automatic or manual adjustment of the height-adjustable mechanisms to restore central alignment.
Solution Approach 2:
The patent replaces manual mechanical adjustment with automated control systems that use angle measuring devices and control units. The control unit processes data from the angle sensors and automatically actuates the height-adjustable mechanisms, substituting manual mechanical operations with an automated electromechanical control system.

AI summary
Soil cultivation implement with a frame on which soil cultivation tools, in particular rotatable disc elements, are arranged in at least two transverse rows one behind the other and engage the soil and are inclined to the direction of travel, wherein the soil cultivation tools in one transverse row are arranged inclined in the opposite direction to the soil cultivation tools in the other transverse row, wherein the frame is arranged on its rear side by means of at least one trailing device rolling on the ground, to which at least one adjusting device arranged between the frame and the trailing device is assigned, in a height-adjustable manner and on its front side by means of at least one support device rolling on the ground, to which at least one adjusting device arranged between the frame and the support device is assigned, in a height-adjustable manner.To significantly simplify the elimination of lateral pull by adjusting the rear transverse row relative to the front transverse row, it is provided that an adjusting device for height adjustment of the soil cultivation tools in the rear transverse row relative to the soil cultivation tools in the front transverse row is assigned to the rear and/or front adjustment device.
