Grit Spreader Support Leg Assembly for Stable Detachable Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil processing machines, such as compactors, require a device for grit distribution during asphalt compaction, but existing solutions do not facilitate easy detachment and stable positioning for both operational and storage purposes.
Innovation Solution
A grit spreader device with a support leg assembly that can pivot between active and inactive positions, allowing for secure coupling to a soil compactor and preventing damage during decoupling, featuring a swivel-slide recess and locking recesses for stable support and adjustable height for easy coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the grit spreader is detachably attached to the soil compactor, then the adaptability and versatility are improved, but the reliability of attachment stability deteriorates
Solution Approach 1:
The support leg units are designed to be pivotable between active and inactive positions, allowing the attachment to dynamically adapt to different operational states. During transport, legs are in inactive position for compactness; during operation, they pivot to active position for stable ground support, thus maintaining reliability while preserving detachable adaptability
Solution Approach 2:
The support leg units act as intermediary elements between the detachable attachment and the ground. They provide a stable reference base that mediates the connection between the mobile attachment and the working surface, ensuring reliability during operation without compromising the detachable nature of the attachment
2Reliability
If the support leg units are positioned in active position for storage, then the reliability of stable positioning is improved, but the ease of operation for coupling deteriorates
Solution Approach 1:
The support leg units are preliminarily positioned in the inactive state by default, ready for quick deployment. The pivot coupling arrangement with locking recesses allows operators to quickly transition between positions without complex adjustments, maintaining ease of operation while ensuring stable positioning when needed
3Ease of operation
If the support leg units are positioned in inactive position during coupling, then the ease of operation for coupling is improved, but the object-affected harmful factors increase due to potential damage
Solution Approach 1:
The pivot coupling arrangement with locking recesses and the ability to position support legs in active state before uncoupling creates a preliminary protective action. This prevents the harmful effect of damage to lower components by ensuring they are properly supported and positioned before the coupling operation occurs

AI summary
An attachment, in particular a grit spreader, for detachable mounting on a soil cultivation machine, in particular a soil compactor, comprises a device body (12), a coupling unit (14) for example on the device body (12) for coupling with a counter-coupling unit (77) on a soil cultivation machine (72), and a support leg assembly (16) with at least one support leg unit (18, 20) pivotable on the device body (12) between an active position and an inactive position, with at least one support leg (22, 24), wherein in the active position the at least one support leg unit (18, 20) is pivoted downwards in a vertical direction (H) to provide a support leg function and in the inactive position the at least one support leg unit (18, 20) is pivoted upwards in the vertical direction (H).
