Round Baler Tailgate Pressure Feedback for Bale Density Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balers connected to tractors lack control over bale density, as the opening of the tailgate is not dependent on the bale's density, limiting user control over the baling process.
Innovation Solution
A baler system with a cylinder-piston actuator connected to a pressure sensor and control unit, which generates an alert signal when the bale reaches a desired density, allowing for precise control over the tailgate movement and bale formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the tailgate opening is controlled by sensors responsive to tailgate position or cylinder piston actuator orientation, then the tailgate can be opened and closed automatically, but the user has limited control on the whole process and cannot control bale density
Solution Approach 1:
The system uses a pressure sensor to provide feedback on the actual bale density during formation. This feedback is displayed to the operator, enabling manual control of the baling process while maintaining automatic tailgate operation. The operator can adjust the baling process based on real-time density information.
2Extent of automation
If the tailgate opening is controlled by sensors responsive to tailgate position, then the tailgate can be opened automatically, but the opening does not depend on bale density
Solution Approach 1:
A pressure sensor is integrated into the system to continuously monitor bale density during formation. The sensor provides real-time feedback to the operator, enabling precise control of bale density while maintaining automatic tailgate operation. The system links tailgate opening to both position sensors and density feedback.
Solution Approach 2:
The system monitors changes in pressure parameters to determine bale density. By tracking pressure variations during the baling process, the system can detect when the bale has reached the desired density and trigger tailgate opening accordingly.
3Device complexity
If no density monitoring system is provided, then the system is simpler, but the user has limited control on the whole process
Solution Approach 1:
The system incorporates a pressure sensor and display unit that provide real-time feedback on bale density to the operator. This allows the operator to control the baling process with full visibility of density parameters, maintaining simplicity while enhancing operational control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise control over bale density by alerting the user to stop the tractor when the bale is fully formed, ensuring optimal bale density and efficient baling process.
Implementation Method 1
A pressure sensor is provided in a baler. The pressure sensor is configured for detecting a pressure inside the closing chamber

AI summary
A baler includes a chamber having a fixed size that receives crops and houses a formed bale. A tailgate is connected to a frame and is movable between a closed position, for cooperating with the frame to delimit the chamber, and an open position, for discharging the formed bale. A conveying assembly delimits the chamber for imparting a rotating movement to the crops contained in the chamber, and has a first portion provided in the frame and a second portion provided in the tailgate. An actuator includes a closing chamber and moves the tailgate from the open position to the closed position upon receiving an actuating fluid in the closing chamber. A binder binds the formed bale, and a pressure sensor detects a control signal representative of a pressure inside the closing chamber of the actuator. A control unit generates an alert signal as a function of the control signal.
