Pivotable Organic Weed Control Device with Mowing and Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural systems lack an efficient method for controlling weeds between rows of planted crops, as existing solutions either fail to effectively remove weeds or do not prevent their re-growth.
Innovation Solution
An organic device is developed that attaches to a sprayer unit, featuring a pivotable shaft with a rotatable blade for mowing weeds and a motor-driven mechanism for delivering weed-control substances between rows, allowing for efficient weed removal and prevention of re-growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical mowing alone is used to control weeds, then weed removal is achieved, but weed re-growth occurs and control is not sustained
Solution Approach 1:
The patent combines mechanical mowing (rotatable blade) with chemical spraying (nozzle system) into a single integrated device. The mowing unit cuts weeds at the base while the spraying unit simultaneously applies herbicide to the cut surfaces and remaining weed parts, achieving both immediate removal and sustained prevention of re-growth through the synergistic effect of mechanical and chemical control methods
Solution Approach 2:
The mowing blade performs preliminary action by cutting weeds at the base before the herbicide is applied. This mechanical cutting exposes fresh wound surfaces that enhance herbicide absorption and translocation, making the subsequent chemical treatment more effective and ensuring sustained weed control
2Reliability
If chemical spraying alone is used to control weeds, then weed growth is suppressed, but mechanical removal of existing weeds is insufficient
Solution Approach 1:
The integrated device merges chemical spraying capability with mechanical mowing functionality. The nozzle system delivers herbicide for reliable growth suppression, while the rotatable blade provides effective mechanical removal of existing weeds, particularly at the base where chemical alone would be less effective
3Device complexity
If a fixed non-pivotable device is used, then structural simplicity is maintained, but adaptability to different row configurations is limited
Solution Approach 1:
The device employs a pivotable shaft that allows the mowing and spraying units to dynamically adjust their position and orientation. This pivotable mechanism enables the device to adapt to different row widths and field configurations while maintaining relatively simple structural design, resolving the contradiction between complexity and adaptability

AI summary
An agricultural system includes a plurality of organic devices for controlling weeds in a planted field, the organic devices being positioned between respective adjacent rows of planted matter in a field. Each the organic devices includes a pivotable shaft having an upper end and a lower end, and a weed-control unit attached to the lower end of the pivotable shaft. The weed-control unit includes a rotatable blade for mowing weeds growing between the adjacent rows of the planted matter. The system further includes at least one motor coupled to one or more of the organic devices for driving the rotatable blade of each weed-control unit.
