This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,856,893.

Background and Problem Solved

The original patent, 'Concave support and adjustment system for combine harvester', provided a rotary threshing system for combine harvesters. However, it had limitations in terms of concave set rotation, gap control, and maintenance. The present invention addresses these limitations by introducing novel solutions for self-leveling hydraulic suspension, real-time crop condition monitoring, adjustable concave-to-rotor gap control, modular quick-release attachment mechanisms, and predictive maintenance.

Novelty and Inventive Step

The present invention's novelty lies in its integration of advanced technologies, such as self-leveling hydraulic suspension, real-time crop condition monitoring, and predictive maintenance, to create a more efficient, reliable, and maintainable concave support and adjustment system. The inventive step is in the combination of these features, which provides a significant improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the invention could include the use of alternative suspension systems, such as pneumatic or electromagnetic suspension. Additionally, the system could be adapted for use in other agricultural harvesting applications, such as forage harvesters or sugarcane harvesters.

Potential Commercial Applications and Market

The enhanced concave support and adjustment system has significant commercial potential in the agricultural industry, particularly in the combine harvester market. The system's ability to improve threshing efficiency, reduce grain loss, and increase overall system reliability makes it an attractive solution for farmers and agricultural companies seeking to increase their productivity and reduce their costs.
