Underground roadway drainage ditch dredging device and dredging method

Abstract

The invention belongs to the technical field of roadway desilting, and particularly relates to an underground roadway drainage ditch desilting device and method. The desilting device comprises two scraping plates which are rotationally arranged on the same rotating shaft and symmetrically arranged along the rotating shaft. The elastic piece is arranged between the two scraping plates and used for enabling the two scraping plates to be in an outward unfolding state all the time; the balancing frame is hinged to the rotating shaft, the hinged axis is perpendicular to the extending direction of the rotating shaft, and the balancing frame is located on the backs of the two scraping plates; the driving assembly is connected to the rotating shaft and drives the rotating shaft to move so as to drive the scraper to move along the drainage ditch. According to the desilting device, the scraped sludge is pushed into the drainage ditch by the scraping plate, at the moment, only the sludge in the drainage ditch needs to be cleaned at a fixed point, the labor intensity of desilting work is greatly relieved, and the working efficiency is improved.
