Excavating Head With Integrated Storage Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excavating heads face challenges with low material removal efficiency and long working times due to the inefficiency of suction pipes in removing excavated material, especially as depth increases, and the slow process of coring methods.
Innovation Solution
The excavating head features a plate-shaped body with protruding excavation tools and a storage chamber with extraction pipes and a frusto-conical storage surface, allowing for efficient collection and discharge of excavated material without reversing the head, utilizing pressurized air for direct flow and gravity-assisted discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If suction pipes are used to remove excavated material, then material removal is possible, but the removal amount is limited and energy consumption increases with depth
Solution Approach 1:
The invention divides the material removal function into two distinct mechanisms: a suction pipe for removing fine particles and dust, and a storage chamber for collecting and discharging larger excavated material. This segmentation allows each mechanism to optimize its function, with the storage chamber handling bulk material removal that would be energy-intensive for the suction pipe alone.
Solution Approach 2:
The storage chamber acts as an intermediary between the excavation tools and the external environment. Material is first collected in the storage chamber during excavation, then discharged externally when the head is extracted. This intermediary storage mechanism decouples the continuous excavation process from the intermittent material discharge, enabling more efficient energy use.
2Productivity
If coring method is used to remove soil, then excavation can proceed, but material accumulates inside the cylindrical body requiring frequent extraction and deposition
Solution Approach 1:
The invention merges the excavation function and material storage function into a single integrated head structure. The storage chamber is built into the head body, allowing material to be accumulated during continuous excavation without needing to stop for discharge. This combination eliminates the time loss associated with frequent extractions and depositions required by coring methods.
Solution Approach 2:
The storage chamber is pre-configured within the head structure before excavation begins. This preliminary preparation allows material to be immediately stored during excavation operations, preventing accumulation issues that would require stopping work for material removal. The chamber is ready to receive material from the outset, enabling continuous productivity.
3Reliability
If traditional heads with central opening and suction pipe are used, then excavation can be performed, but productivity is reduced due to low material removal speed
Solution Approach 1:
The invention segments the material removal system into dual channels: a central suction pipe for fine particles and a peripheral storage chamber for bulk material. This segmentation allows simultaneous operation of both removal mechanisms, dramatically increasing overall material removal speed while maintaining excavation continuity that relies on reliable, uninterrupted material evacuation.
Solution Approach 2:
The invention adds a spatial dimension to material removal by positioning the storage chamber peripherally around the central suction pipe. This dimensional arrangement allows both systems to operate independently and simultaneously without interfering with each other, maximizing material removal capacity while ensuring continuous excavation operation.
