Laterally Adjustable Three-Point Hitch Implement Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tractor-mounted implement systems often misalign during turns and veering, leading to crop damage, uneven application of chemicals, and inadequate soil cultivation due to limited lateral movement and stability, especially when the tractor is off-course.
Innovation Solution
A connecting apparatus for tractors featuring a slidable framework with laterally extending rails and drivers, such as hydraulic cylinders, to maintain implement alignment and stability, utilizing GPS or laser guidance systems to automatically adjust the implement's position relative to the tractor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional three-point hitch systems are used, then the implement can be attached to the tractor, but the implement misaligns during turns and veering occurs
Solution Approach 1:
The patent implements a laterally adjustable framework that can dynamically change its lateral position relative to the tractor during operation. The framework includes adjustment mechanisms that allow it to move left and right to compensate for tractor veering and maintain proper implement alignment, transforming a static connection into a dynamic adaptive system.
Solution Approach 2:
The system incorporates guidance systems (GPS, laser, or visual markers) that provide feedback on the implement's position and orientation. This feedback enables automatic or manual adjustment of the framework's lateral position to correct misalignment caused by tractor turns and veering, ensuring the implement remains properly aligned with the field path.
2Strength
If the implement is rigidly connected to the tractor, then structural stability is maintained, but lateral adjustment capability is lost
Solution Approach 1:
The connection system is divided into multiple independent components: the tractor, the adjustable framework, and the implement. The framework acts as an intermediate segment that can laterally adjust its position while maintaining strong connections to both the tractor and implement, allowing lateral movement without compromising connection strength.
Solution Approach 2:
The framework incorporates dynamic adjustment mechanisms that allow it to change its lateral configuration in response to operational conditions. These mechanisms include telescopic arms, adjustable linkages, or motorized positioners that enable the framework to adapt its lateral position while maintaining structural integrity and strong connections.
3Device complexity
If manual adjustment mechanisms are used, then device complexity is reduced, but adjustment precision and speed are insufficient
Solution Approach 1:
The system replaces manual mechanical adjustment with automated control systems. Motors, hydraulic actuators, or electric positioners automatically adjust the framework's lateral position based on feedback from guidance systems, eliminating the need for manual operation while achieving high precision and rapid response to alignment requirements.
Solution Approach 2:
The system uses electronic sensors and control systems to precisely measure and control the framework's lateral position parameters. GPS coordinates, laser distance measurements, or visual marker detection provide precise parameter data that enables automated adjustment mechanisms to achieve accurate alignment with sub-inch precision.
