Step-Down Spring Seat for Vibratory Screen Horizontal Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vibratory screen deck assembly design requires vertical displacement and removal of coil springs for repair or replacement, which is cumbersome, costly, and time-consuming.
Innovation Solution
A step-down spring seat assembly with detachable adapter plates allows for horizontal displacement and removal of coil springs, facilitating easier and faster replacement without the need for vertical lifting of the screen deck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If coil springs are mounted using traditional vertical displacement method, then the screen deck assembly remains stable during operation, but spring replacement becomes time-consuming and labor-intensive requiring vertical lifting of the entire screen deck
Solution Approach 1:
The spring mounting system is segmented into separate components: a base plate attached to the screen deck, individual spring seats for each spring, and detachable mounting mechanisms. This segmentation allows springs to be accessed and replaced independently without moving the entire screen deck assembly, directly resolving the contradiction by enabling easy spring replacement while maintaining overall system stability
Solution Approach 2:
The invention introduces dynamic, adjustable mounting mechanisms that allow the spring seats to be quickly positioned and secured at different heights and locations. The base plate can be repositioned along the screen deck frame, and spring seats can be adjusted vertically to accommodate different spring lengths, enabling rapid spring replacement without fixed vertical displacement requirements
2Ease of repair
If traditional vertical spring mounting is used, then structural simplicity is maintained, but maintenance cost increases due to equipment rental and labor requirements for vertical lifting
Solution Approach 1:
The spring replacement system is designed to be self-service capable, with all necessary mounting components (base plate, spring seats, fastening mechanisms) integrated directly onto the screen deck assembly. Mechanics can perform spring maintenance using only basic hand tools without requiring specialized lifting equipment or external assistance, thereby reducing maintenance costs while improving ease of repair
Solution Approach 2:
The base plate and spring seat design incorporates universal mounting features that can accommodate different spring types, sizes, and positions. The system serves multiple functions: securing springs, allowing height adjustment, enabling quick release, and providing structural support, all while using standardized components that reduce manufacturing complexity and maintenance cost
3Reliability
If coil springs are fixed in vertical position, then proper spring support and vibration isolation are achieved, but replacement requires raising the entire screen deck assembly which reduces productivity
Solution Approach 1:
The spring mounting function is extracted from the main screen deck structure and placed into separate, removable spring seats that attach to both the deck and the spring. This extraction allows the spring to be removed and replaced independently while the screen deck remains in its fixed, vibration-isolated position, thereby maintaining reliability during operation and enabling quick spring replacement that improves maintenance productivity
Solution Approach 2:
Spring seats serve as intermediary components between the screen deck and the coil springs. These mediators provide the necessary vibration isolation and structural support while enabling easy spring replacement. The spring seats can be quickly detached and reattached, allowing spring maintenance without disturbing the vibration isolation characteristics of the overall assembly, thus maintaining both reliability and productivity

AI summary
A step-down spring seat assembly secured to a vibratory screen machine is configured to receive one or more universal adapter plate assemblies, to which one or more compression springs is secured. The universal adapter plate assemblies are secured to a top surface of the step-down spring seat assembly, and one or more spring guide castings are connected to the one or more universal adapter plate assemblies. Compression springs are positioned atop the spring guide castings, and are secured to a top adapter plate assembly that is connected to one or more universal adapter plate assemblies positioned above the one or more compression springs.
