SLUDGE SCRAPER
Document Type and Number:
Japanese Patent JP3513618
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To execute traveling more surely by eliminating slip or the like by a method wherein a scraper is linked to a rotary driver, and after the scraper obtains respective attitudes of scraping and returning, a clutch linking mechanism with which power transmission to the scraper is placed in a cut off state, is provided.
SOLUTION: A wheel 54 is rotated in the direction F or the direction R following regular rotation or reverse rotation of a rotary driver 53, and consequently a sludge scraper advances or returns according to the direction F or the direction R. The sludge scraper comes to a position wherein a principal scraper 42 exceeds a rear end side of a pit with advance in the direction F. A subscraper 48 may be also advanced to the position of exceeding the same rear end side. Then, with the revers rotation, the sludge scraper enters a return attitude, and a principal scraper 42 and a sub-scraper 43 are lifted as a virtual line. The principal scraper 42 is lifted forewards, and the sub-scraper 43 is respectively lifted rearwards. For the linking, change of ascent or descent is executed with a clutch linking mechanism 63.
