Blade Levelling Assembly with Rotatable Accessory Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current levelling technologies face challenges in achieving precise horizontal levelling on slopes and mounds, requiring additional expensive and heavy rotational assemblies, and often necessitate multiple operations with different machines for ground preparation and levelling, increasing time and cost. Additionally, laser guidance systems are typically only implemented on blade implements, limiting their application to other accessories.
Innovation Solution
A multi-adjustable blade levelling assembly that allows for vertical and rotational movement of the blade relative to the vehicle, incorporating linear actuators and stabilising linkages to maintain blade inclination and elevation, enabling attachment to standard connections without additional rotational assemblies, and featuring a rotatable accessory mounting system for integrated laser guidance control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional rotational assemblies are added to achieve precise inclination adjustment, then levelling precision on slopes is improved, but device complexity and weight increase
Solution Approach 1:
The blade assembly is made dynamically adjustable through hydraulic actuators that enable real-time modification of blade inclination and elevation. This dynamic adjustment capability allows the blade to maintain precise horizontal levelling on slopes without requiring complex fixed rotational assemblies, resolving the contradiction between levelling precision and device complexity
Solution Approach 2:
The system changes operational parameters (blade inclination angle and elevation height) through hydraulic actuation to achieve precise levelling on varying terrain. By dynamically altering these parameters rather than using complex mechanical rotational assemblies, the system achieves high levelling precision while maintaining relatively simple device architecture
2Manufacturing precision
If multiple machines are used for ground preparation and levelling, then ground preparation quality is improved, but productivity and time efficiency deteriorate
Solution Approach 1:
The levelling assembly is designed with universal functionality to perform multiple operations including ground levelling, slope grading, and mound shaping in a single integrated system. This multi-functionality eliminates the need for multiple separate machines while maintaining high ground preparation quality, thereby improving productivity and time efficiency
Solution Approach 2:
The patent combines ground preparation and levelling functions into a single integrated blade assembly that can perform both tasks. By merging multiple functions into one device, the system achieves high-quality ground preparation without requiring sequential operations with multiple machines, thus enhancing productivity
3Measurement precision
If laser guidance systems are integrated only on blade implements, then control precision for levelling is improved, but adaptability to other accessories deteriorates
Solution Approach 1:
The laser guidance system is designed with universal adaptability to control not only the blade assembly but also various accessories such as scarifiers and rakes. This universal control capability maintains precise laser-guided control while enhancing adaptability to different implements and accessories
4Ease of operation
If standard Quick Hitch connections are used, then ease of attachment is improved, but inclination adjustment capability deteriorates
Solution Approach 1:
The system maintains simple Quick Hitch connections for easy attachment while incorporating dynamic hydraulic actuation mechanisms that enable precise inclination and elevation adjustment. The dynamic adjustment capability compensates for the limited static adjustment of standard Quick Hitch connections, achieving both ease of attachment and inclination adjustment capability
