Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural implements for soil tilling and fertilization lack efficient mechanisms for uniform soil distribution and fertilizer incorporation, especially in clumpy or wet conditions, and often require multiple passes for optimal fertilizer application.
Innovation Solution
The agricultural implement features a tillage device with coulter wheels and depth control devices, including a swirl device with rotating tines that intercept and redistribute soil and residue, ensuring uniform soil mixing and fertilizer incorporation within the tilled strip, while allowing for high-speed operation and reduced soil loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional tillage devices are used, then basic soil tilling is achieved, but uniform soil distribution and fertilizer incorporation are insufficient especially in clumpy or wet conditions
Solution Approach 1:
The patent employs a rotating depth control device with multiple tines that dynamically interact with the soil. The rotation creates varying angles of attack and soil engagement patterns, allowing the device to handle clumpy and wet conditions more effectively while maintaining uniform soil distribution and fertilizer incorporation.
Solution Approach 2:
The depth control device is segmented into multiple tines distributed around the rotating wheel. This segmentation allows different portions of the device to work on different sections of the soil strip simultaneously, improving overall uniformity while each individual tine can adapt to varying soil conditions through the rotational motion.
2Manufacturing precision
If multiple passes are used for optimal fertilizer application, then fertilizer distribution improves, but productivity decreases and time increases
Solution Approach 1:
The patent combines tillage and fertilizer incorporation operations into a single integrated device. The depth control device with rotating tines performs both soil cultivation and fertilizer mixing in one pass, eliminating the need for separate fertilizer application passes while maintaining uniform distribution through the rotational mixing action.
Solution Approach 2:
The rotating depth control device provides continuous soil mixing and fertilizer incorporation throughout its rotation cycle. This continuous action ensures uniform fertilizer distribution within the tilled strip without requiring multiple discrete passes, thereby maintaining productivity while achieving the desired uniformity.
3Adaptability or versatility
If conventional tillage devices are used, then basic soil preparation is achieved, but equipment complexity increases when additional equipment is added for fertilizer incorporation
Solution Approach 1:
The depth control device is designed as a universal component that performs multiple functions: it controls tillage depth, mixes soil, and incorporates fertilizer. By integrating these functions into a single rotating device with tines, the patent reduces the need for separate specialized equipment while maintaining the ability to handle various soil conditions and fertilizer application requirements.
4Productivity
If high-speed operation is pursued, then productivity increases, but soil uniformity and fertilizer incorporation quality may deteriorate
Solution Approach 1:
The rotating depth control device maintains effective soil mixing and fertilizer incorporation at high operating speeds through its rotational motion. The rotation creates dynamic soil engagement that continues to provide thorough mixing even at higher forward speeds, allowing the system to maintain uniformity while increasing productivity through faster operation.

AI summary
An agricultural implement for tilling at least a strip of soil to be planted includes a tillage device for penetrating and tilling a strip of soil and displacing soil and residue upwardly, and a depth control device laterally offset from the centerline of the strip of soil and mounted for rotation about an axis of rotation located rearwardly of the tillage device and positioned to intercept soil and residue displaced upwardly by the tillage device. Multiple tines mounted on the depth control device extend laterally away from the depth control device toward the centerline to intercept a portion of the soil and residue displaced upwardly by the tillage device. The tines are attached to the depth control device only at one end of each tine, and the free ends of the tines terminate laterally short of the centerline and vertically between the elevations of the upper and lower edges of the depth control device.
