Abstract

PURPOSE: To scoop sediment at one stroke to prevent spillage in the return process by operating the body of a scraper for removing waste such as sludge settling in a culvert of a sewer with pulling and returning ropes while being supported with a bellcrank.
CONSTITUTION: When a scraper 14 is pulled with a pulling rope 8, a wheel 17 pivoted on a bellcrank 16 turns to scrape a sediment 5 into the scraper 14 with a scraping blade 10. When the scraper 14 is pulled with a returning rope 9 in the return stroke, the wheel 17 comes under the scraper 14 to maintain the bottom height 24. Thus, there is no sediment raked in the return stroke.
