Soil-Working Machine Movable Disc Beams Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil working machines lack the ability to adjust working depth precisely, accommodate differentiated disc wear, and work effectively across the entire width of the chassis, limiting their operational efficiency and depth adjustment capabilities.
Innovation Solution
The design incorporates multiple rows of oscillating discs with movable disc-carrying beams that allow for independent adjustment of working depth and wear compensation, featuring a system with pivoting supports and actuators for precise axial movement and visual wear indicators for easy adjustment, enabling simultaneous working of the ground by multiple rows during a single pass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple rows of discs are added to increase working width, then productivity increases, but device complexity increases and soil cultivation quality deteriorates due to inability to adjust depth independently
Solution Approach 1:
The machine divides the disc system into multiple independent rows, each with its own adjustable beam. This segmentation allows each row to be controlled independently for depth adjustment while maintaining overall system manageability despite increased complexity from multiple rows
Solution Approach 2:
The patent implements movable beams that can dynamically adjust their position vertically to control disc depth. Each beam is equipped with adjustment mechanisms allowing real-time depth modification during operation, transforming a static structure into a dynamic, adaptable system
2Reliability
If disc wear varies between rows, then reliability deteriorates, but adjustment capability is limited in known machines
Solution Approach 1:
The patent applies local quality by allowing each row's beam to be adjusted independently based on local wear conditions. Each row can have its depth customized to compensate for specific wear patterns in that area, rather than requiring uniform adjustment across all rows
Solution Approach 2:
The system enables parameter changes by allowing independent modification of the vertical position parameter for each beam. This changes the operational parameters of each row to compensate for wear, maintaining consistent cutting depth despite varying disc conditions
3Productivity
If working depth is increased for better soil cultivation, then productivity improves, but ease of operation deteriorates due to lack of precise adjustment
Solution Approach 1:
The patent implements preliminary action by providing adjustment mechanisms that allow depth to be set and optimized before operation begins. The beams can be pre-adjusted to the required depth positions, ensuring optimal soil cultivation from the start of operation
