[0023] The present utility model will be further described in detail in conjunction with the accompanying drawings.

[0024] Please refer to Figure 1 - Figure 6 , a building wall plastering device provided by the present utility model, including a base 1, an electric telescopic rod 2 and a plastering mechanism 3, wherein the plastering mechanism 3 includes a plastering component 4, a suction pump 5 and a material placement box 6.

[0025] Please refer to Figure 1 and Figure 2 , the working end of the electric telescopic rod 2 is fixedly connected to the middle of the upper end surface of the base 1, the extended end of the electric telescopic rod 2 is fixedly connected to the lower end surface of the material placement box 6, the suction pump 5 is installed at the bottom of the inner cavity of the material placement box 6, the plastering component 4 is installed on one side of the top of the material placement box 6, the suction pump 5 is communicated with the plastering component 4 through a hose, and the mortar inside the material placement box 6 is conveyed to the plastering component 4. The electric telescopic rod 2 can drive the material placement box 6 to move linearly in the vertical direction through expansion and contraction, and cooperate with the plastering component 4 with mortar to plaster the wall.

[0026] It should be supplemented that universal wheels are installed at the four corners of the bottom of the base 1 to facilitate the movement of the base 1 or lock the position of the base 1.

[0027] It should also be added that a feed inlet is provided at the top of the material storage box 6 .

[0028] See also Figures 3 to 6 The plastering assembly 4 includes an installation box 41 and a plastering drive assembly 42. The installation box 41 includes a box body 412. The side walls and the top diagonal positions of the box body 412 are fixedly connected with guide plates 411. A filter screen 414 is arranged near the connection position between the box body 412 and the guide plate 411. A mounting plate 415 is fixedly connected to the top of the inner cavity of the box body 412. A placement groove 413 is provided on the top of the mounting plate 415. The placement groove 413 is communicated with the top of the box body 412. The plastering drive assembly 42 includes a plastering plate 421 and a drive plate 422. The plastering plate 421 includes a scraper 4212. One end of the scraper 4212 is fixedly connected with a drive gear shaft 4213. The drive gear shaft 4213 is fixedly connected to the upper end surface of the box body 412 through two groups of mounting plates. A discharge hole 4211 is provided on the upper end surface of the scraper 4212. The drive plate 422 is meshed and connected with the drive gear shaft 4213.

[0029] Specifically, the drive plate 422 includes a tooth plate 4222, the top of which is fixedly connected to an anti-collision convex plate 4221, the lower end of the tooth plate 4222 extends into the mounting groove 413 and is fixedly connected to a plurality of groups of elastic components 4223, and the plurality of groups of elastic components 4223 are arranged at intervals and one end away from the tooth plate 4222 is fixedly connected to the bottom of the mounting groove 413.

[0030] It should be noted that when vertically plastering, the guide plate 411 at the side position is located at the bottom of the scraper 4212, and the extended length is less than the extended length of the scraper 4212. When top plastering, the guide plate 411 at the top position is located on the side of the scraper 4212, and the extended height is less than the extended height of the scraper 4212.

[0031] It can be understood that the mortar is conveyed through the hose and through the discharge hole 4211 to the upper end surface of the scraping plate 4212. The elastic component 4223 abuts against the toothed plate 4222 so that the toothed plate 4222 meshes with the driving toothed shaft 4213, so that an included angle b is kept fixed between the end of the scraping plate 4212 away from the driving toothed shaft 4213 and the numerical wall surface. After adjusting the distance between the end of the scraping plate 4212 and the wall surface in advance, only by pushing the plastering component 4 upward through the electric telescopic rod 2, the wall surface in the covered area of the scraping plate 4212 can be plastered from bottom to top. The mortar falling during the plastering process is collected by the deflector 411 at the side position, and then filtered through the filter screen 414 and recycled back into the material placing box 6. When the scraping plate 4212 moves to the height of the upper end of the vertical wall surface, the top wall surface squeezes the anti-collision convex plate 4221. At this time, control the electric telescopic rod 2 to continue to extend. The top wall surface pushes the toothed plate 4222 to compress the elastic component 4223 and move towards the bottom of the placement groove 413. At the same time, the driving toothed shaft 4213 meshing with the toothed plate 4222 rotates. When the toothed plate 4222 moves to the lowest end, the driving toothed shaft 4213 drives the scraping plate 4212 to rotate until the included angle between the end of the scraping plate 4212 and the top wall surface is a. At this time, the electric telescopic rod 2 remains unchanged, and the base 1 is pushed to move linearly along the direction parallel to the vertical wall surface, so as to plaster the covered area of the scraping plate 4212 on the top wall surface. The mortar falling during the plastering process is diverted and recycled through the deflector 411 at the top position. The wall surfaces at different positions can be covered with plaster through simple operations, improving the applicability of the equipment.

[0032] It should be noted that when the toothed plate 4222 is not affected by external forces, the lower end compresses the elastic component 4223 and remains stationary in the placement groove 413. The elastic component 4223 is a spring with a high elastic modulus. The driving force generated by the scraping plate 4212 when plastering the vertical wall surface will not cause obvious influence on the shape of the elastic component 4223.

[0033] It should also be noted that the anti-collision convex plate 4221 is made of high-elastic materials such as rubber and plastic to avoid damaging the top wall surface when plastering the top wall.

[0034] It should be added that the anti-collision convex plate 4221 can be set as a roller with an elastic material wrapped on the outside, which is rotatably connected to the top of the toothed plate 4222 to reduce the friction between the anti-collision convex plate 4221 and the top wall surface.

[0035] Principle: The mortar is put into the material placing box 6 through the feeding port. The base 1 is pushed by the universal wheels to keep the scraping plate 4212 at an appropriate distance from the vertical wall surface to be plastered and the universal wheels are locked. The suction pump 5 works to transport the mortar inside the material placing box 6 to the upper end surface of the scraping plate 4212 through the hose and the discharge hole 4211. The mortar flows along the inclined scraping plate 4212. The electric telescopic rod 2 drives the material placing box 6 to move upward, so that the mortar on the upper end surface of the scraping plate 4212 is evenly scraped and applied on the vertical wall surface in the covered area of the scraping plate 4212. When the end of the scraping plate 4212 moves to the upper end of the vertical wall surface, the protruding anti-collision convex plate 4221 is squeezed by the top wall surface, pushing the toothed plate 4222 to compress the elastic component 4223 and move into the placement groove 413. The downward moving toothed plate 4222 meshes with the driving toothed shaft 4213, so that the driving toothed shaft 4213 rotates counterclockwise to drive the scraping plate 4212 to swing, making the included angle between the end of the scraping plate 4212 and the top wall surface be a. The electric telescopic rod 2 stops working, and the base 1 is pushed to move linearly along the direction parallel to the vertical wall surface to plaster the wall surface in the top area covered by the scraping plate 4212. The mortar falling during the plastering process is diverted by the diversion plate 411 and then filtered by the filter screen 414 and recycled into the material placing box 6 to avoid interfering with the operators and the construction environment. After the top plastering is completed, the equipment is restored. By moving the equipment parallel, the above operations can be repeated to perform covering plastering on the vertical and bottom wall surfaces, greatly improving the plastering efficiency.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
