Articulated Pulling Arm with Hydraulic Angle Adjustment for Plows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural machinery, such as plows, require manual and discrete adjustments of the articulated traction arm's position, necessitating the operator to exit the vehicle for each adjustment, which is inefficient and inconvenient.
Innovation Solution
An articulated traction arm device with a sector-shaped adjustment piece connected by a pivot joint and a length-adjustable rigid elongated member, such as a hydraulic cylinder, allows for continuous and remote control of the arm's pivoting position, enabling automatic attachment and detachment of secondary machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual and discrete adjustments of the articulated traction arm's position are used, then the machine structure remains simple, but the operator must exit the vehicle for each adjustment, reducing operational efficiency and safety
Solution Approach 1:
The patent replaces manual mechanical adjustment with a hydraulic actuation system. The hydraulic cylinder (element 12) provides powered adjustment of the articulated traction arm (element 4), eliminating the need for manual intervention and allowing the operator to remain in the vehicle. This substitution of mechanical manual adjustment with hydraulic actuation directly resolves the contradiction by improving productivity while accepting increased device complexity.
Solution Approach 2:
The patent employs a hydraulic cylinder (element 12) to automate the adjustment of the articulated traction arm's position. The hydraulic system enables remote control from within the vehicle, allowing continuous adjustment during operation without requiring the operator to exit. This application of hydraulics directly addresses the productivity issue while introducing the necessary complexity for automated control.
2Loss of time
If discrete manual adjustments are made, then the adjustment mechanism remains simple, but the number of adjustments required increases time consumption and reduces productivity
Solution Approach 1:
The hydraulic actuation system replaces manual adjustment mechanisms, enabling continuous and rapid repositioning of the articulated traction arm. This substitution eliminates the time-consuming nature of discrete manual adjustments while accepting the complexity of the hydraulic control system.
Solution Approach 2:
The patent transforms the static, discrete adjustment system into a dynamic, continuous adjustment system. The hydraulic cylinder enables the traction arm to be repositioned continuously during operation, reducing the time lost to adjustments while introducing dynamic control complexity.
3Ease of operation
If the articulated traction arm requires frequent manual adjustment, then the adjustment mechanism remains simple, but operator safety is reduced due to repeated vehicle exits
Solution Approach 1:
The hydraulic control system replaces manual adjustment mechanisms, allowing the operator to adjust the articulated traction arm from within the vehicle. This substitution improves ease of operation and operator safety by eliminating repeated vehicle exits, while accepting the complexity of the hydraulic control system.
4Adaptability or versatility
If the traction arm is fixed in position, then the structure remains simple, but the ability to perform multiple soil working operations simultaneously is limited
Solution Approach 1:
The patent transforms the fixed traction arm into a dynamically adjustable system. The hydraulic cylinder enables the arm to be repositioned continuously to accommodate different soil working operations, improving adaptability and versatility while introducing the complexity of active positioning control.
Solution Approach 2:
The articulated traction arm with hydraulic adjustment serves multiple functions by being repositionable for different soil working operations. This multi-functionality improves adaptability while requiring the complex hydraulic positioning system to enable the versatile operation.
