Channel Excavation Device with Segmented Cutting and Rotating Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for excavating channels are inefficient in dislodging and discharging material, as they often require slow movement and lack effective mechanisms for neat cutting and material transport.
Innovation Solution
A device with a container and rotor, featuring cutting edges at the front end and rotating knife elements within, which dislodge and move soil to the rear end for efficient discharge through an adjustable discharge opening, allowing for faster movement and adjustable width to accommodate varying channel dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If rotating discs are used for cutting away flanks in combination with a container, then the flanks can be cut away, but the material dislodging and discharging becomes inefficient
Solution Approach 1:
The cutting function is segmented between stationary cutting edges at the front end for flank cutting and rotating knife elements for material dislodging. This segmentation allows each component to be optimized for its specific function, resolving the contradiction between cutting quality and excavation efficiency.
Solution Approach 2:
The knife elements are mounted on a rotating rotor that spins at high speed to dislodge and transport material efficiently. This dynamic rotation enables continuous material removal and discharge, significantly improving excavation productivity while the stationary cutting edges maintain cutting precision.
2Reliability
If the device moves forward slowly to excavate material, then material can be processed, but the excavation speed is reduced
Solution Approach 1:
The rotating knife elements continuously dislodge, transport, and discharge material throughout their rotation cycle. This continuous action allows the device to maintain high excavation speeds without compromising material handling effectiveness, as the material removal process never interrupts the forward movement.
3Device complexity
If the container width is fixed, then the structure is simple, but it cannot accommodate varying channel dimensions
Solution Approach 1:
The container width is made adjustable through movable side walls that can be positioned at different distances from each other. This dynamic adjustment capability allows the container to adapt to various channel widths while maintaining a relatively simple overall structure, resolving the contradiction between structural simplicity and adaptability.
