A wall coating and scraping machine for construction

Abstract

The invention discloses a wall space spraying and scraping machine for buildings. The wall space spraying and scraping machine comprises a rack, a supporting arm, a box body, a top support, a spraying mechanism, a lifting mechanism and universal wheels; the spraying mechanism is arranged on one side of the box body; a spraying and scraping mechanism comprises a scraping plate, side plates, second air cylinders, a supporting plate, a sealing strip and convex lugs, wherein the side plates are arranged on the two sides of the scraping plate, the side plates are movably connected to the convex lugs at one end of a collecting box through pin shafts, the multiple second air cylinders are arranged at the bottom of the scraping plate, the tails of the second air cylinders are fixedly connected to the supporting plate, the supporting plate is fixedly connected to the side wall of the collecting box, and the sealing strip is arranged at the tail of the scraping plate; the supporting arm is arranged on one side of the rack, the top support is arranged on the upper portion of the supporting arm, and the lifting mechanism is arranged at the lower portion of the top support; and the lifting mechanism comprises a motor, a reduction box, a synchronous pulley, a synchronous belt, a transmission shaft, a fixing base and an extrusion plate. By means of the wall space spraying and scraping machine, the inner walls of the buildings are effectively sprayed, the wall space is flat and smooth, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of architectural coating equipment, in particular to a wall coating and scraping machine for architectural use.

Problems solved by technology

[0002] At present, the walls of buildings need to be painted with putty powder and paint during interior decoration. Traditional wall and top gypsum and putty spraying are all done manually. The stirred slurry is put in a small bucket and painted by hand. Brushing, brushing up manually one knife at a time, this method can be used in rural areas or personal home decoration, but it can no longer meet the development needs of the industry. Later, spraying machines appeared in the industry, and the operating efficiency of spraying machines has been greatly improved. , but the effect is not very ideal, the flatness is poor and there is a sense of unevenness, and the user experience is not good

[0003] The existing mechanical putty painting equipment adopts push brushing or roller coating, which has corresponding deficiencies in manufacturing cost, product portability and use efficiency. Today, with the increasing cost of productivity and the technological development of the decoration industry, there is an urgent need for more Efficient and more convenient process equipment to meet the growing decoration requirements

[0004] After retrieval, the application number is 2015107104148, an interior and exterior wall paint roller coating machine, including a brushing structure and a suction structure, and the brushing structure communicates with the suction structure through a delivery pipe, wherein the brushing The structure comprises a roller brush, a bracket bend and a pole; the present invention carries out the painting of the interior and exterior walls by the roller brush, and the following problems occur: 1) the pressure of the roller coating wall surface is difficult to control, which easily causes the overflow of the paint during the roller brushing process. flow, waste of paint, uneven roll coating on the wall, inconsistent moisture content during the drying process, and easy cracking on the wall surface; 2) During the roll coating process, when the delivery pipe is at different heights, it is easy to cause intertwined roots, which is very confusing, resulting in inconvenience for construction , it is necessary to manually arrange the pipeline, which is time-consuming and labor-intensive
