Intelligent Baler Sensor Calibration and Chamber Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural balers face challenges in achieving optimal bale density and throughput due to the inverse relationship between material quantity and compression density, leading to inefficient operation and wear on the machinery, and the need for compromising between density and throughput during startup.
Innovation Solution
The agricultural baler employs multiple sensors to measure bale parameters directly and indirectly, with a controller prioritizing direct sensors during startup to ensure predetermined bale characteristics, and subsequently calibrating and prioritizing indirect sensors for optimal operation, allowing for faster and more accurate control of the baling process.

1Productivity
If a large quantity of material is fed into the bale chamber on each stroke, then the throughput of the baler is improved, but the density of the bale decreases
Solution Approach 1:
The patent applies dynamics by making the baling chamber dimensions adjustable during operation. The width and height of the baling chamber can be dynamically changed to optimize the balance between throughput and density. By adjusting the chamber size, the system can accommodate varying material quantities while maintaining consistent bale density, thus resolving the contradiction between feeding large quantities for high throughput and maintaining compression density.
2Manufacturing precision
If a small quantity of bale material is fed into the bale chamber on each stroke, then the density of the bale is improved, but the throughput of the baler decreases
Solution Approach 1:
The patent applies dynamics by making the baling chamber dimensions adjustable during operation. The width and height of the baling chamber can be dynamically changed to optimize the balance between throughput and density. By adjusting the chamber size, the system can accommodate varying material quantities while maintaining consistent bale density, thus resolving the contradiction between feeding large quantities for high throughput and maintaining compression density.
3Device complexity
If the baling chamber dimensions are fixed, then the device complexity is reduced, but the adaptability to different material quantities and density requirements is limited
Solution Approach 1:
The patent applies dynamics by making the baling chamber dimensions adjustable during operation. The width and height of the baling chamber can be dynamically changed to optimize the balance between throughput and density. By adjusting the chamber size, the system can accommodate varying material quantities while maintaining consistent bale density, thus resolving the contradiction between feeding large quantities for high throughput and maintaining compression density.
Solution Approach 2:
The patent applies universality by designing the baling chamber with adjustable dimensions that can adapt to different material types, quantities, and density requirements. This multi-functional capability allows a single baling machine to handle various baling scenarios without requiring multiple fixed-dimension chambers, thus improving adaptability while maintaining reasonable device complexity.

AI summary
An agricultural baler includes a baling chamber and a pre-compression chamber. The pre-compression chamber is configured to gather crop material and to periodically form a slice of the crop material and introduce the slice into the baling chamber. The baling chamber includes a plunger provided for moving in the baling chamber thereby compressing slices of crop material into a bale. The agricultural baler further includes multiple sensors and a controller configured for controlling operation of the agricultural baler based on inputs of the multiple sensors. A first subset of the multiple sensors is directly related to bale parameters, and a second subset of the multiple sensors is indirectly related to the bale parameters. The controller is configured to control the operation of the agricultural baler and calibrate the sensors of the second subset based on outputs of sensors of the first subset.
