Excavator Compactor Plate with Rotating High Bend
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing add-on compactors for excavators have limitations in effectively compacting soil, especially when approaching boundaries or in tight spaces, due to their fixed design and lack of flexibility in positioning the compactor plate.
Innovation Solution
The add-on compactor features a rotating device that allows the compactor plate to pivot vertically, with a high bend on one edge section and a flat edge on the other, enabling flexible positioning and adjustable angle of attack, and can be remotely controlled for enhanced compaction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the compactor plate has a high bend on one edge section, then the compactor can be positioned more flexibly and prevent digging into soil, but the effective compaction area is reduced compared to a fully flat plate
Solution Approach 1:
The compactor plate incorporates a rotatable device that enables the high bend to be dynamically repositioned around a vertical axis during operation. This allows the operator to rotate the high bend to different locations along the plate's edge, adapting the compaction profile to match varying terrain conditions and boundary positions, thus resolving the contradiction between flexibility and effective area.
Solution Approach 2:
The compactor plate is divided into distinct functional zones: a high bend section for boundary work and a flat section for general compaction. This segmentation allows each portion to perform its specialized function optimally while the rotatable device enables dynamic reconfiguration of how these segments are positioned relative to the work area.
2Adaptability or versatility
If the compactor plate is rotated to position the high bend for effective working, then adaptability to local conditions improves, but the device complexity increases due to the rotating mechanism
Solution Approach 1:
The rotatable device serves multiple functions: it positions the high bend for optimal boundary work, enables the flat section to engage with the ground for enhanced compaction area, and allows quick reconfiguration between different compaction modes. This multi-functionality justifies the added complexity by providing versatile adaptability to various working conditions.
3Productivity
If the high bend is used for boundary compaction, then time is saved compared to manual repositioning, but the manufacturing complexity increases due to the bent edge section
Solution Approach 1:
The high bend is pre-formed on the compactor plate during manufacturing, creating a ready-to-use feature for boundary compaction work. This preliminary preparation eliminates the need for manual repositioning or attachment of separate boundary compaction tools during operation, thereby increasing productivity despite the additional manufacturing step required to create the bent section.
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
This design increases the effective compaction area, saves time, and allows for better soil stabilization by adjusting the compactor plate's angle and contact pressure, particularly useful in confined spaces like ditches or canals, while preventing the compactor from digging into the soil.
Implementation Method 1
A hydraulic eccentric drive is used to generate vibrations
Implementation Method 2
an axis of rotation of a rotary device arranged between the coupling device and the compactor plate, with which the compactor plate can be rotated about an axis that is at least substantially vertical during operation
