Soil Cultigator With Dynamic Tool Spacing Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soil cultivators for mechanical weed control are inefficient as they require manual adjustment of hoe shares and harrow tines, which interrupts the cultivation process and cannot be adjusted precisely enough to avoid damaging young crops, especially in the early growth phase.
Innovation Solution
A soil cultivator with a frame-like element that can change its extent transverse to the traveling direction, allowing soil cultivation tools to be adjusted in distance and angle via swiveling connecting elements, enabling precise and efficient weed control without stopping the tractor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of hoe shares and harrow tines is used, then the distance between tools can be changed, but the cultivation process must be interrupted and adjustment precision is insufficient
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the distance between hoe shares and harrow tines can be changed automatically during operation. The frame-like element with variable extent allows the tool spacing to be adjusted on-the-fly without stopping the tractor, transforming a static tool configuration into a dynamic one that adapts to field conditions while maintaining continuous cultivation productivity
Solution Approach 2:
The adjusting mechanism is designed to be self-regulating through the swiveling connecting elements that automatically respond to changes in the frame-like element's extent. The system adjusts tool positions autonomously based on the frame configuration, reducing the need for manual intervention and maintaining operational continuity

AI summary
A soil cultivator comprises a frame attachable to a tractor and at least one processing unit attached to the frame. The processing unit has a frame-like element, a first soil cultivation tool attached to the frame-like element via a first connecting element, a second soil cultivation tool attached to the frame-like element via a second connecting element, and a swiveling axis element. The first soil cultivation tool and the second soil cultivation tool are arranged on different sides of the swiveling axis element. The first connecting element has a first annular section, and the second connecting element has a second annular section. The first and the second connecting elements are arranged so that they can swivel around the swiveling axis element such that a change in the extent of the frame-like element can effect a change in the distance between the first and the second soil cultivation tools.
