Mineral Feed Apparatus Adjustable Gap Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mineral material feed apparatuses face challenges in adjusting the distance between the feed conveyor and the feed hopper, leading to issues like material leakage and operational inefficiencies due to manufacturing inaccuracies and wear, which complicates the fixing and operation of the feeder.
Innovation Solution
A feed apparatus with adjustable distance means, comprising a second frame fixed by distance adjustment mechanisms, including screws and levers, allowing stepless adjustment of the gap between the transport surface and the feed box, and compensating for wear by altering the vertical fixing point of seals, thereby reducing material wedging and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the feed conveyor is fixed with bolts against the feed hopper to form a stiff feed entity, then the structural stability is improved, but the adjustability of the distance between the feed conveyor and feed hopper deteriorates
Solution Approach 1:
The patent replaces the fixed stiff connection with a dynamic adjustment mechanism consisting of bolts, adjusting washers, and lever systems that allow the distance between the feed conveyor and feed hopper to be modified. This enables the system to adapt to different operational requirements while maintaining structural stability through proper mechanical fastening.
Solution Approach 2:
The invention allows changing the distance parameter between the feed conveyor and feed hopper by using adjusting washers of different thicknesses and lever mechanisms. This parameter adjustment capability resolves the contradiction by enabling both stable fixation and flexible distance modification according to manufacturing tolerances and operational needs.
2Adaptability or versatility
If adjusting washers are used to adjust the distance between the feed conveyor and feed hopper, then the adjustability is improved, but the complexity of the fixing process deteriorates
Solution Approach 1:
The adjustment mechanism is divided into separate functional components: bolts for basic fixation, adjusting washers for distance calibration, and lever systems for securing. This segmentation allows each component to perform its specific function independently, making the overall complex task of adjustment more manageable and systematic.
Solution Approach 2:
The adjusting washers are pre-positioned on the bolts before final tightening, allowing the distance to be set in advance. This preliminary action simplifies the fixing process by separating the distance adjustment step from the final securing step, making the overall process more organized and less complex.
3Ease of operation
If the gap between the feed hopper side wall and conveyor belt is too large, then the ease of operation is improved, but material leakage worsens
Solution Approach 1:
The patent enables precise adjustment of the gap size between the feed hopper side wall and conveyor belt through the distance adjustment mechanism. This allows optimization of the gap parameter to achieve the right balance: large enough to prevent material wedging and facilitate smooth operation, but small enough to prevent material leakage through the gap.
4Ease of manufacture
If manufacturing inaccuracies are not compensated, then the manufacturing cost is reduced, but the operational reliability deteriorates
Solution Approach 1:
The adjustment mechanism serves as a self-compensation system that allows operators to correct manufacturing inaccuracies in the field. Instead of requiring high-precision manufacturing, the system provides built-in adjustment capabilities that enable operators to compensate for tolerances and achieve proper alignment, maintaining reliability without increasing manufacturing costs.
