[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses an interior wall plastering device for decoration construction. Figure 1-3 A plastering device for interior wall for decoration construction comprises a base 1, a telescopic rod 2 is fixed at the center of the upper surface of the base 1, a mortar box 3 is fixed at the top of the telescopic rod 2, two rollers 4 are rotatably connected inside the mortar box 3, four screw barrels 5 are rotatably connected to the upper surface of the base 1, a worm gear 6 is fixed below the outer surface of the screw barrel 5, a screw 7 is threadedly connected inside the screw barrel 5, and the four screws 7 are divided into two groups, and a bottom beam 8 is fixed to the bottom of each group of two screws 7, and the left and right ends of the bottom beam 8 are rotatably connected to the horizontal wheel 9, a worm 10 is rotatably connected inside the base 1, and the outer surface of the worm 10 is meshed with the four worm gears 6, and the bottom of the base 1 is connected to the bottom of the base 1. Side grooves 11 are provided on the left and right sides of the surface, and two longitudinal wheels 12 are rotatably connected inside the side grooves 11; the mortar box 3 can be raised by the telescopic rod 2, so that the drum 4 can contact the top wall and plaster the top wall ceiling. By setting the horizontal wheel 9 and the longitudinal wheel 12, the drum 4 can perform more uniform and straight operations during plastering, avoiding repeated plastering, resulting in differences in the thickness of the mud and plaster, and improving the quality of plastering. The bolts 16 and the screw plates 17 can drive the scraper 18 to move laterally, and then approach or move away from the drum 4, so that the scraper 18 can scrape off the mortar hair on the outer surface of the drum 4 that absorbs excessive mortar.

[0023] Reference Figure 4A push-pull frame 13 is provided on the right side of the upper surface of the base 1, a through-type card hole 24 is opened on the lower surface of the push-pull frame 13, a spring groove 21 is opened at the lower inner side of the push-pull frame 13, a spring plate 23 is slidably connected inside the spring groove 21, and a spring 22 is fixed between the left end of the spring plate 23 and the inner wall of the spring groove 21, so that the horizontal wheel can be raised for horizontal plastering.

[0024] Reference Figure 1-4 A clamping rod 19 is fixed on the right side and the front of the upper surface of the base 1, and a clamping slot 20 is opened on the outer surface of the clamping rod 19. The clamping rod 19 on the right side is located inside the clamping hole 24, and the right end of the spring plate 23 is plugged into the inside of the clamping slot 20. The two clamping rods 19 are adapted to the clamping hole 24. The push-pull frame 13 can be installed to different positions through the two clamping rods 19.

[0025] Reference Figure 1-2 The left and right sides of the mortar box 3 are rotatably connected with bolts 16, and the outer surface of the bolt 16 is threadedly connected with a screw plate 17. A scraper 18 is fixed to the side of the screw plate 17 close to the mortar box 3. The end of the scraper 18 away from the screw plate 17 penetrates into the inner side of the mortar box 3. The mortar box 3 is slidably connected with the scraper 18, driving the scraper 18 to move laterally, approaching or away from the drum 4.

[0026] Reference Figure 2 The opposite sides of the two scrapers 18 are inclined structures, and the opposite ends of the two scrapers 18 are respectively in contact with the outer surfaces of the two rollers 4, and the scrapers 18 are used to scrape off excess mortar on the rollers 4.

[0027] Reference Figure 1-4 The push-pull frame 13 is an L-shaped structure, and a through hand groove 14 is opened on the upper part of the push-pull frame 13. The lower surface of the push-pull frame 13 is in contact with the upper surface of the base 1. The right end of the worm 10 penetrates to the right side of the base 1 and is fixed with an operating block 15. The hand groove 14 is convenient for people to hold the push-pull frame 13.

[0028] The implementation principle of the interior wall plastering device for decoration construction in the embodiment of the present application is as follows: when in use, mortar is poured into the plastering slurry box 3, and the bolt 16 is turned according to the required plastering thickness of the wall surface, so that the screw plate 17 drives the scraper 18 to move horizontally, close to or away from the roller 4, so that the scraper 18 can scrape off the excessive mortar absorbed by the slurry hair on the outer surface of the roller 4, and then the mortar box 3 is raised by operating the telescopic rod 2, and the roller 4 contacts the top wall. At this time, the push-pull frame 13 can be pushed and pulled to utilize the lifting horizontal wheel 9 to perform horizontal plastering operations. When longitudinal movement is required, the push-pull frame 13 is turned to move horizontally. The operating block 15 is moved to rotate the worm 10. Under the transmission of the worm wheel 6, the screw barrel 5 rotates, so that the screw 7 drives the bottom beam 8 and the horizontal wheel 9 to rise, so that the horizontal wheel 9 is away from the ground and retracted into the base 1. At this time, the four longitudinal wheels 12 are in contact with the ground, and the spring plate 23 is pressed to retract it. The push-pull frame 13 is removed and installed at the front clamping rod 19, which can push the push-pull frame 13 to move the device longitudinally forward and backward; the setting of the two types of horizontal and vertical wheels allows more uniform and straight work during plastering, avoids repeated plastering, causes differences in mud and plaster thickness, and improves the quality of plastering.
