Agricultural Tillage Control System for Penetration Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The forces acting on disc blades in agricultural tillage implements can become unbalanced, leading to variations in penetration depth and reduced effectiveness of tillage operations.
Innovation Solution
A control system that includes a controller configured to receive signals from pressure sensors and angle sensors, and to control a tilt actuator to maintain fluid pressure within a target range and the angle of the rolling basket frame within a target range, thereby maintaining consistent penetration depth of the disc blades.

Engineering Contradiction Analysis
1Manufacturing precision
If the tillage implement traverses the field with disc blades, then soil breaking operation is performed, but the forces acting on disc blades become unbalanced resulting in variations in penetration depth
Solution Approach 1:
The system uses pressure sensors to monitor the forces acting on disc blades in real-time and feeds this information back to the controller. The controller then adjusts the tilt actuator to balance the forces, maintaining consistent penetration depth. This closed-loop feedback mechanism directly addresses the force balance stability issue.
Solution Approach 2:
The system dynamically adjusts the tilt angle of the main frame using the tilt actuator based on real-time force measurements. This dynamic adjustment allows the system to adapt to changing soil conditions and maintain force balance, resolving the contradiction between operational effectiveness and force stability.
2Productivity
If the disc blades are arranged in front row and rear row, then tillage operation is performed, but variations in penetration depth reduce the effectiveness of tillage operation
Solution Approach 1:
Pressure sensors monitor the penetration depth and forces on both front and rear disc blade rows, providing real-time feedback to the controller. The controller adjusts the tilt actuator to maintain uniform penetration depth across all rows, ensuring consistent tillage effectiveness throughout the field.
Solution Approach 2:
The system changes the tilt angle parameter of the main frame dynamically to compensate for variations in penetration depth. By adjusting this key parameter, the system maintains uniform soil breaking depth across multiple disc blade rows, improving overall tillage effectiveness.

AI summary
A control system for an agricultural tillage implement includes a controller configured to receive a pressure sensor signal indicative of a fluid pressure within a rolling basket cylinder and/or an angle sensor signal indicative of an angle of a rolling basket frame relative to a main frame. The rolling basket cylinder is configured to couple to the main frame and to the rolling basket frame. The controller is also configured to control a tilt force applied by a tilt actuator to the main frame to maintain the fluid pressure within a threshold fluid pressure range of a target fluid pressure and/or to maintain the angle of the rolling basket frame within a threshold angle range of a target angle. The tilt actuator is configured to couple to a hitch assembly and to apply the tilt force to the main frame.
