The utility model relates to a special dust automated processing of building wall fitment machinery, including red -tape operation board, pushing mechanism, two adjustment mechanism and two absorbingmechanism, pushing mechanism install on the right side of red -tape operation board upper end, two adjustment mechanism symmetries are installed in the left side of red -tape operation board upper end, an absorbing mechanism is all installed to every adjustment mechanism upper end. The utility model discloses can solve to scrape on the current wall and sweep in -process that the dust goes on retrieving to the dust that falls into ground again and need the staff need wear the gauze mask when scraping the dust on sweeping the wall to carry out work, can not avoid the suction of dust completely,there is the potential safety hazard, the staff stands for a long time and cause the potential safety hazard easily on table surface, the staff can collect the dust that falls down with the help of the instrument scraping when sweeping, the dust that descends slowly and lightly of part can carry out the centralized processing after sweeping scraping again, time -consuming is long, be difficult toclean up, difficult problems such as the big and inefficiency of work intensity of labour, can realize the automated processing's of dust function.
