Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a plastering device for building construction. Background Technology

[0002] The function of plastering equipment is to evenly apply mortar to the walls and floors of a building. By using plastering equipment, not only can the efficiency of plastering work be improved and the construction cycle shortened compared to manual plastering, but the thickness of the applied mortar can also be made more uniform, ensuring the flatness and aesthetics of the building surface, and laying a good foundation for subsequent decoration and renovation work.

[0003] Construction plastering equipment is an application of plastering equipment in specific fields. It is designed for the construction environment and requirements. The plastering equipment needs to adapt to the complex conditions of different construction sites. Whether it is high-altitude operation in high-rise buildings or operation in confined spaces, it must be able to operate stably. The equipment must not only ensure the quality of mortar application, but also have flexibility and mobility so as to efficiently complete the plastering task in various building structures and different construction stages.

[0004] In traditional plastering equipment, aggregates in the mortar tend to adhere to and accumulate on the inner wall of the delivery pipes over long-term use, causing localized blockages and resulting in uneven thickness streaks on the wall surface, affecting the plastering quality. However, existing technology uses ceramic-coated pipes with spiral guide vanes inside to rotate the mortar during delivery, reducing adhesion and ensuring stable mortar delivery. During plastering operations, the friction between the mortar and the wall surface, as well as the movement of the plastering disc, causes a large amount of dust to be raised and dispersed in the air, which not only reduces the air quality at the construction site but also harms the health of construction workers.

[0035] Specifically, the feeding pump 502 starts, drawing the ash material through the discharge pipe 501 and conveying it to the plastering disc component 503, which then performs the plastering operation on the wall. Simultaneously, the dust collection mechanism 2 operates synchronously. Two connecting blocks 201 are fixed to the front and rear sides of the plastering housing 1.

The storage tank 302 is fixedly connected to the inner wall of the support ring 301. The storage tank 302 is used to store ash material. The top of the storage tank 302 is fixedly connected to a sealing cover 303, which prevents the ash material from drying out due to excessive contact with the outside environment. The top of the sealing cover 303 is fixedly connected to a mounting base 304. Mounting base 304 provides a mounting position for servo motor 305. Servo motor 305 is fixedly connected to the inner wall of mounting base 304. Servo motor 305 provides power for the rotation of the spiral stirring blade shaft 306. The output end of servo motor 305 is fixedly connected to the spiral stirring blade shaft 306. The spiral stirring blade shaft 306 drives the spiral blades to stir the ash material, preventing ash material from settling and clumping. A feed chute 307 is provided on the top left side of the sealing cover 303, facilitating the entry of ash material into the storage tank 302.

The outer wall of the rotating frame 3081 is fixedly connected to the inner wall of the spiral stirring blade shaft 306 to ensure that the rotating frame 3081 can rotate with the spiral stirring blade shaft 306. The left and right sides of the U-shaped frame 3081 are slidably connected with hanging plates 3082. The position of the hanging plates 3082 can be adjusted by sliding to be close to the inner wall of the storage tank 302. Multiple fixing screws 3083 are equidistantly arranged on the left and right ends of the front side of the U-shaped frame 3081. The fixing screws 3083 are used to fix the position of the hanging plates 3082 on the U-shaped frame 3081.

[0037] Specifically, when it is necessary to stir the ash material inside the storage tank 302, the servo motor 305 starts, driving the spiral stirring blade shaft 306 to rotate. The spiral blades on the spiral stirring blade shaft 306 stir the ash material inside the storage tank 302, preventing the ash material from settling and clumping, and ensuring that the ash material is always in a uniform and loose state, so that it can be smoothly transported to the troweling plate component 503 for troweling operations through the feeding mechanism 5. At the same time, the cleaning component 308 plays a role, and the return frame 3081 is fixed on the spiral stirring blade shaft 302. As the spiral agitator 306 rotates, the hanging plate 3082 can slide to the left and right sides of the spiral frame 3081. By adjusting the fixing screw 3083, the position of the hanging plate 3082 on the spiral frame 3081 can be changed so that it is close to the inner wall of the storage tank 302. During the rotation of the spiral agitator shaft 306, the hanging plate 3082 scrapes off the ash material adhering to the inner wall of the storage tank 302, further avoiding the accumulation of ash material residue, ensuring the normal flow of ash material in the storage tank 302, and solving the problem of ash material adhesion and sedimentation affecting the use in the prior art.

The bottom of the fixed base 605 is fixedly connected to the top right side of the base plate 7, so that the fixed base 605 is stably installed on the base plate 7 and provides support for the entire lifting mechanism 6.

[0039] Specifically, the limiting block 11 can prevent the guide slide rod 601 from rising excessively and detaching from the plaster shell 1; the buffer pad 12 can buffer when the guide slide rod 601 rises to the limit position to reduce impact; the hopper 10 can collect the plaster material that falls during plastering; the laser positioning device 13 can assist construction personnel in accurately determining the plastering position and range; and the bottom of the fixed base 605 is fixedly connected to the top right side of the base plate 7, so that the fixed base 605 is stably installed on the base plate 7.

[0040] Working principle: When the device is running, the feeding pump 502 starts, drawing out the mortar through the discharge pipe 501 and conveying it to the plastering disc component 503. The plastering disc component 503 then performs plastering operations on the wall. Simultaneously, the dust collection mechanism 2 operates synchronously. Two connecting blocks 201 are fixed to the front and rear sides of the plastering shell 1. The right end of the dust collection branch pipe 202 on its inner wall is connected to the dust collection hood 208, which can effectively collect the dust raised during the plastering process. The dust enters the dust collection main pipe 203 through the dust collection branch pipe 202, and then reaches the dust collection pump 205 through the filter pipe 204 at the bottom right end. The filter mechanism 4 plays a key role in this process. The coarse filter 401 first intercepts larger dust particles, then the medium filter 402 filters medium-sized dust particles, and finally the fine filter 403 further blocks fine dust, ensuring that the dust entering the wall is filtered out. The air entering the vacuum pump 205 is relatively clean. The vacuum pump 205 discharges the filtered air through the exhaust pipe 207. The lifting mechanism 6 can adjust the position of the plastering device according to the height of the wall. The servo motor 603 starts, driving the drive gear 604 to rotate and mesh with the toothed plate 602, so that the guide slide rod 601 slides up and down along the front and rear sides of the plastering shell 1. The fixed base 605 rises and falls accordingly, thereby adjusting the height of the plastering plate component 503 to meet the plastering needs of walls of different heights. During the plastering process, the vacuum mechanism 2 collects and filters dust in time, reducing the amount of dust in the air at the construction site. It effectively solves the problem of dust spreading due to friction between mortar and wall surface and the movement of the plastering plate, protects the health of construction workers, and improves the air quality at the construction site.

[0041] Furthermore, when it is necessary to stir the ash material inside the storage tank 302, the servo motor 305 starts, driving the spiral stirring blade shaft 306 to rotate. The spiral blades on the spiral stirring blade shaft 306 stir the ash material inside the storage tank 302, preventing the ash material from settling and clumping, and ensuring that the ash material is always in a uniform and loose state, which facilitates its smooth delivery to the troweling device 503 for troweling operations via the feeding mechanism 5. At the same time, the cleaning component 308 plays its role, with the return frame 3081 fixed to the spiral stirring blade shaft 302. As the spiral agitator 306 rotates, the hanging plate 3082 can slide on the left and right sides of the spiral frame 3081. By adjusting the fixing screw 3083, the position of the hanging plate 3082 on the spiral frame 3081 can be changed so that it is close to the inner wall of the storage tank 302. During the rotation of the spiral agitator shaft 306, the hanging plate 3082 scrapes off the ash material adhering to the inner wall of the storage tank 302, further avoiding the accumulation of ash material residue, ensuring the normal flow of ash material in the storage tank 302, and solving the problem of ash material adhesion and sedimentation affecting the use in the prior art.
