Beach Cleaner Separation Rods Guide Heavy Debris
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beach cleaners that scoop garbage and stones with sand face efficiency issues due to sand accumulation in the recovery unit, leading to reduced recovery efficiency and loss of heavy items like large stones and plastic bottles.
Innovation Solution
A beach cleaner with a separation rod unit comprising longitudinal and lateral members that bridge between the scraper and the recovery unit, allowing heavy items to be guided back into the recovery unit and pulverizing sand lumps to maintain efficient sand screening, preventing backflow and improving recovery efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a gap is provided between the separator and the recovery unit to reduce sand accumulation, then sand recovery efficiency is improved, but heavy garbage and stones drop through the gap and cannot be recovered
Solution Approach 1:
The separator is divided into multiple longitudinal members (rods) with spaces between them, creating a segmented structure that can selectively separate different types of debris based on size and weight while maintaining overall separation functionality
Solution Approach 2:
Different regions of the separator have different properties - the longitudinal members are arranged to create varying gap sizes and orientations, allowing certain areas to capture heavy items while other areas allow sand to pass through
2Loss of substance
If the separator scrapes all sand and garbage together to maximize collection, then comprehensive garbage recovery is achieved, but sand accumulates excessively in the recovery unit reducing efficiency
Solution Approach 1:
The longitudinal members act as intermediary elements between the scraping action and the recovery unit, selectively intercepting heavy garbage while allowing sand to pass through to the recovery unit, thus mediating the separation process

AI summary
A beach cleaner for recovering relatively heavy garbage or stones while minimizing the amount of sand entering a garbage recovery unit. The beach cleaner includes a frame formed by a longitudinal member and a lateral member. A towed portion is provided at the front portion of the frame for towing by a tow vehicle. A separator is provided at the lower front portion of the frame to separate and scrape garbage from sandy ground. A recovery unit is provided behind the separator to collect garbage scraped onto the mesh member. At least one separation rod unit is provided having a plurality of longitudinal members and a lateral member for joining the rear ends of the respective longitudinal members. The front end of at least one separation rod unit is secured to the separator so as to be turnable in the up-and-down direction.
