Wing Fold Hydraulic Pressure Control for Deeper Disc Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The penetration depth of disc blades in agricultural implements is limited by the mass of the wing sections, leading to reduced effectiveness in soil tillage and potential soil compaction during transport and tillage operations.
Innovation Solution
A hydromechanical linkage assembly with a blocking valve and driver system controls fluid pressure within the wing fold assembly, allowing for high-pressure application during transport to facilitate rapid wing section rotation and low-pressure operation for increased penetration depth during tillage, reducing soil compaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high fluid pressure is applied to the wing fold assembly during transport, then rapid wing section rotation is facilitated, but penetration depth of disc blades is reduced due to increased wing section mass effect
Solution Approach 1:
The system dynamically adjusts fluid pressure based on operational mode: high pressure during transport for rapid wing rotation, and low pressure during tillage for maximum penetration depth. The blocking valve assembly enables this dynamic pressure regulation by controlling fluid flow to the wing fold cylinder.
Solution Approach 2:
The blocking valve assembly changes the pressure parameter of the hydraulic fluid by blocking or allowing flow based on wing section position. This parameter change enables the system to switch between high-pressure transport mode and low-pressure tillage mode, resolving the contradiction between rotation speed and penetration depth.
2Force
If low fluid pressure is applied to the wing fold assembly during tillage, then penetration depth of disc blades is increased, but wing section rotation speed is reduced
Solution Approach 1:
The system dynamically adjusts fluid pressure based on operational mode: low pressure during tillage for maximum penetration depth, and high pressure during transport for rapid wing rotation. The blocking valve assembly enables this dynamic pressure regulation by controlling fluid flow to the wing fold cylinder.
Solution Approach 2:
The blocking valve assembly changes the pressure parameter of the hydraulic fluid by blocking or allowing flow based on wing section position. This parameter change enables the system to switch between low-pressure tillage mode and high-pressure transport mode, resolving the contradiction between penetration depth and rotation speed.
3Force
If wing section mass is increased to improve penetration depth, then structural strength is improved, but soil compaction increases during transport and tillage operations
Solution Approach 1:
The system uses hydraulic pressure control to compensate for wing section mass. By applying low pressure during tillage operations, the system reduces the effective force exerted by the wing section on the soil, thereby maintaining penetration depth while minimizing soil compaction. During transport, high pressure enables rapid rotation without increasing wing mass.
Solution Approach 2:
The blocking valve assembly dynamically changes the pressure parameter to regulate the force exerted by the wing section. Low pressure during tillage reduces soil compaction while maintaining adequate penetration, and high pressure during transport enables rapid wing rotation without requiring increased wing mass.
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
The system enhances the operational efficiency of agricultural implements by increasing penetration depth of ground-engaging tools while minimizing soil compaction, improving both transport and tillage performance.
Implementation Method 1
The valve assembly may control a wing fold cylinder of the agricultural implement, which may drive a wing section of the frame to rotate relative to a center section of the frame. When the wing section rotates, a driver coupled to the frame of the agricultural implement may actuate the blocking valve to adjust fluid pressure within the wing fold assembly.
