A Load Cell-Free Solution for Weighing

The agricultural industry increasingly demands innovative solutions to enhance efficiency and productivity, while minimizing overhead costs of an advanced system. Large farms cultivating forage crops for the Dairy and Livestock sectors require high-quality, dense bales that retain their nutritional value. Bale weight serves as a critical parameter for assessing production yields, managing inventory and facilitating fair trade in the industry. Traditional weighing systems reliant heavily on load cells, can pose limitations in terms of cost, complexity and maintenance. This paper presents an advanced model-based weighing system de-signed specifically for balers machine. It utilizes mathematical models and dynamic torque monitoring techniques to accurately estimate the weight of bales just after the baling process. The Bale weight calculation is achieved by measuring reverse pressure experienced during bale handling and monitoring the pitch angle to compensate for measurements over inclines in varying terrain. This innovative methodology circumvents the challenges traditionally associated with load cells, including the need for frequent calibration, additional weight and the costs associated with large load cell installations. The advancement has significant implications for scalability and profitability, allowing for optimized decision-making processes in agricultural operations. With the capability to function effectively in off-road conditions and diverse terrains, this system represents a substantial technological leap that addresses the evolving challenges of modern agriculture. By demonstrating the potential of this design, the paper illustrates how advanced engineering solutions can enhance resource allocation, optimize feed management and distribution, support long-term planning, and contribute to the sustainability of agricultural practices without incurring additional costs.
