Abstract

PURPOSE: To effectively support the reaction force by scraping motion by connecting both ends of the scraping mechanism link and a beam provided to the scraping mechanism by means of curved links and moving links and the midpoint of the moving link and the beam by a supporting link, respectively freely trunably.
CONSTITUTION: To scrape the precipitate 7 deposited in the bottom of a basin 1 to the channel 8 side, the chain 5 of a scraping mechanism 2 is driven in the arrow direction by an underwater motor or the like and the precipitate is scraped by the flight 6 mounted to the chain 5. At this time, the reaction force exerted upon the scraping mechanis, 2 along with the scraping motion is supported by a supporting link 23 by way of a moving link 20, whereby the scraping work is surely accomplished. On the other hand, to lift the mechanism 2 for the purpose of maintenance and inspection or for moving the same to another basin, a hoisting drum 26 is driven to hoist a wire rope 27, thereby lifting said mechanism. When the wire rope 27 is hoisted, the roller 21 at the top end of the link 20 moves right along a roller guide 22, and this causes the link 12 to bend at a pin 17 as a center, whereby the lifting of the mechanism 2 is accomplished.
