Abstract

Scraping device at sedimentation basins for removing sediment collected on the bottom of the basin, comprising a wagon which reciprocates on the botton of the basin by means of rope drive means and which is provided with scraping members (11, 12) taking in one direction of the wagon a scraping position, and in the other direction of movement a passive return position. The device is easily pulled and easily guided in that it is provided with guiding wheels (22, 23) for guidance along a guiding beam (21) arranged in the basin centrally relative to the wagon, while the weight of the wagon is taken up by special carrying wheels (15, 20) abutting against the bottom of the basin. The traction ropes (27, 28) for traction of the wagon are fastened directly in the wagon framing, and the operation of the scrapes between their working position and return position is separated from the ropedriving in that the scrapes are tilted at both ends of the basin when contacted by stationary shoulder members within the basin.
