Description

Technical Field

[0001] The utility model relates to the technical field of automatic plastering robots, in particular to an automatic wall plastering robot. Background Art

[0002] When painting a wall, cement mortar is applied to the wall. Generally, the mortar is spread evenly by manpower, which is time-consuming and labor-intensive. In recent years, with the continuous emergence of new technologies and new measures, it has become possible to change the cement wall plastering work from manual to machine operation. By using an automatic plastering machine, the mortar on the wall can be spread evenly. The automatic plastering robot consists of a body, a working plate, a connecting rod, a universal wheel, a slide rail, a movable plate, a slider, an electric hydraulic rod, a first motor, a movable arm, a collection box, a scraper, a slide groove and a threaded rod. When the automatic plastering robot is used, the body is pushed and moved to the wall to be plastered through the universal wheel. The first motor is started to drive the threaded rod to rotate, so that the movable arm in the slide groove moves, and then the scraper moves. The scraper spreads the mortar on the wall evenly, so that the scraped mortar enters the collection box. After the movable arm reaches the top of the inner wall of the slide groove, the first motor stops rotating, and the electric hydraulic rod on the working plate connected by the connecting rod is started to move the movable plate upward, so that the scraper continues to rise, and the slider slides in the slide rail, thereby completing the even spreading of the wall mortar.

[0003] The inventor found in his daily work that when the automatic plastering robot is in use, since the automatic plastering robot spreads the mortar on the inner wall evenly with a scraper, the depth of the mortar is changed by replacing the scraper. Since the scraper is fixed by a threaded fixing method and a movable arm, the fixing position is narrow, making it difficult to insert the tool, which makes the replacement process take a long time, thereby affecting the construction efficiency.

[0032] Working principle:

[0033] When the automatic screeding robot is in use, the machine body 1 is pushed and moved to the wall that needs screeding through the universal wheel 6, and the first motor 11 is started to drive the threaded rod 16 to rotate, so that the moving arm 12 in the slide 15 moves, and then the scraper 14 is driven to move. The scraper 14 spreads the mortar on the wall evenly, so that the scraped mortar enters the collection box 13. After the moving arm 12 reaches the top of the inner wall of the slide 15, the first motor 11 stops rotating, and the electric hydraulic rod 10 on the working plate 4 connected to the connecting rod 5 is started, so that the moving plate 8 moves up, so that the scraper 14 continues to rise, and the slider 9 slides in the slide rail 7, thereby completing the smoothing of the wall mortar. When the scraper 14 is quickly replaced, the air pump 27 is started, so that the gas in the air bag 26 in the circular groove 25 is extracted through the air pipe 28, and the air bag 26 drives the semicircular magnetic block 2 4 moves, thereby separating the two semicircular magnetic blocks 24 in the slot 23 from the annular groove 22 on the post 21, dragging the scraper 14 so that the scraper 14 is removed, and then dragging the scraper 14 to be replaced so that the post 21 is inserted into the slot 23, and the gas generated by the air pump 27 is input into the air bag 26 through the air pipe 28 again, so that the air bag 26 swells, so that the two semicircular magnetic blocks 24 are stuck in the annular groove 22, and the scraper 14 is fixed, so as to achieve the effect of quickly replacing the scraper 14. By setting the annular magnet 29 and the semicircular magnetic block 24, the post 21 is further limited. When it is necessary to collect the scraped mortar, the second motor 34 is started to drive the auger 33 to rotate, so that the mortar in the collection box 13 moves to the side of the bellows 31, so that the mortar falls into the bellows 31 and finally falls into the collection box 32.
