Abstract
Description
Technical Field
[0001] This invention relates to the field of decoration and construction technology, specifically a building exterior wall plastering machine. Background Technology
[0002] Painting exterior walls is an extremely important process in building construction. Traditionally, painting is mainly done manually, which is inefficient and labor-intensive. The quality of the painting is also affected by factors such as the worker's skill level, human observation bias, and physical fluctuations, making it difficult to guarantee the overall quality of the painting. Furthermore, as the height of the painting increases, scaffolding must be erected, which puts workers at heights and increases the risk of accidents.
[0003] A search revealed a patent with publication number CN218406314U that discloses a building exterior wall plastering machine. The machine uses a mortar receiving point at the center of the box to collect recycled mortar for reuse. A leveling mechanism is located at one end of the box to level the plaster on the building exterior wall. By adjusting the tilt angle of the leveling mechanism, the amount of mortar falling can be reduced. At the same time, a through groove is provided on the leveling plate in the leveling mechanism to collect excess mortar into the box, thereby reducing mortar waste.
[0004] However, in practical applications, it was found that the above-mentioned patent has defects. The device cannot efficiently plaster curved exterior walls during use.

The automatic material leveling and obstacle avoidance component includes a suspension frame and a vision camera. The vision camera is fixedly installed on the top side of the suspension frame facing the wall.
[0010] An arc-shaped wall reinforcement mechanism is fixedly installed on one side of the bottom of the lifting platform and located at the bottom of the variable-form coating assembly.

[0030] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] This invention provides an improved exterior wall plastering machine. The technical solution of this invention is as follows:
[0032] like Figures 1-6 As shown, a building exterior wall plastering machine includes a fixed base 1, two lifting control frames 2, and a lifting platform 3. The two lifting control frames 2 are symmetrically distributed on both sides of the top of the fixed base 1, and the lifting platform 3 is installed between the two lifting control frames 2. The machine also includes:
[0033] The variable-form coating component 4 is fixedly installed on the top of the lifting platform 3. The variable-form coating component 4 includes a rotating feeding platform 401, a tilt adjustment telescopic rod 402, and a hinge frame 403. The top of the rotating feeding platform 401 is equipped with a feeding conveyor belt. In actual use, the slurry is placed on the feeding conveyor belt. As the whole rises, the slurry at the edge is consumed. The feeding conveyor belt continuously transports the slurry to the side to ensure the plastering effect.
[0034] Two tilt-adjustable telescopic rods 402 are fixed on the top sides of the lifting platform 3 respectively. The two ends of the rotating feeding platform 401 are connected to the telescopic ends of the tilt-adjustable telescopic rods 402 through the hinge frame 403 respectively. The tilt angle of the rotating feeding platform 401 is adjusted by the tilt-adjustable telescopic rods 402 at both ends, which facilitates the movement and conveying of slurry to the side.
[0035] The variable-form plastering component 4 also includes an arc-shaped adjustable telescopic rod 404, a connecting shaft 405, and an elastic plastering rubber 406. An opening is provided on one side of the rotating feeding platform 401, and the elastic plastering rubber 406 is disposed on one side of the opening. The arc-shaped adjustable telescopic rod 404 is fixedly disposed within the opening, and the connecting shaft 405 is fixedly installed on the telescopic end of the arc-shaped adjustable telescopic rod 404. One side of the elastic plastering rubber 406 is bonded to the connecting shaft 405. The elastic plastering rubber 406 is located on the side of the rotating feeding platform 401 and has a certain degree of elasticity, used for plastering the mortar. The variable-form plastering component 4 performs plastering, and the plastering shape is adjustable, thus effectively adapting to the shape of curved exterior walls. This makes the plastering edge of the variable-form plastering component 4 more closely match the curved exterior wall, ensuring plastering effect while improving plastering efficiency.
[0036] Automatic material leveling and obstacle avoidance component 5; Automatic material leveling and obstacle avoidance component 5 is fixedly installed on one side of the top of the lifting platform 3, and is located on top of the variable form coating component 4. Automatic material leveling and obstacle avoidance component 5 includes a suspension frame 501 and a vision camera 502. The vision camera 502 is fixedly installed on the top side of the suspension frame 501 facing the wall. During the lifting process of the lifting platform 3, the automatic material leveling and obstacle avoidance component 5 detects the wall information. When encountering a large opening, that is, the reserved groove of the outer wall, it automatically cuts off the mortar to prevent the reserved groove from being filled. The level of intelligence is effectively improved, no additional manual control is required, and it can also flatten the unevenly piled mortar at the bottom, making the mortar more uniform.
[0037] The curved wall reinforcement mechanism 6 is fixedly installed on one side of the bottom of the lifting platform 3, and is located at the bottom of the variable form coating component 4. The curved wall reinforcement mechanism 6 includes multiple horizontal movement control telescopic rods 603 and multiple curved coating plates 604. The curved coating plates 604 are connected to the telescopic ends of the horizontal movement control telescopic rods 603, and the curvature of the multiple curved coating plates 604 is different. The curved wall reinforcement mechanism 6 is located at the bottom and is used in conjunction with the variable form coating component 4. After the variable form coating component 4 performs initial smoothing, it is reinforced by the curved wall reinforcement mechanism 6 to ensure the fixation effect of the mortar.
[0038] Furthermore, the lifting control frame 2 includes a limiting frame 201, a limiting rod 202, a cable reel 203, and a cable 204. The limiting rod 202 is welded inside the limiting frame 201. The two sides of the lifting platform 3 are respectively threaded onto the limiting rods 202 inside the two lifting control frames 2. The cable reel 203 is fixedly installed on the top inner wall of the limiting frame 201. The cable 204 is installed on the winding end of the cable reel 203. One bottom end of the cable 204 is fixed to the outer wall of the lifting platform 3. The position of the lifting platform 3 is restricted by the limiting rod 202, so that the lifting platform 3 can only move up and down. The lifting and moving of the lifting platform 3 is achieved by the cable reel 203 winding the cable 204, so that the lifting platform 3 can move flexibly between the two limiting frames 201 for lifting and plastering treatment of the exterior wall.
[0039] Furthermore, the automatic material leveling and obstacle avoidance component 5 also includes a mounting base 503, a blocking control telescopic rod 504, and a blocking plate 505. The suspension frame 501 is screwed to one side of the top of the lifting platform 3, the mounting base 503 is welded to the bottom of the suspension frame 501, the blocking control telescopic rod 504 is fixedly installed at the bottom of the mounting base 503, and the blocking plate 505 is connected to the telescopic end of the blocking control telescopic rod 504. The suspension frame 501 serves as the mounting bracket, and the visual camera 502 collects information about the exterior wall. When encountering a large opening, i.e., a reserved groove in the exterior wall, the blocking control telescopic rod 504 extends, controlling the blocking plate 505 to descend, thereby automatically cutting off the slurry on the rotating feeding platform 401 in advance. This ensures that when the rotating feeding platform 401 moves to the reserved groove, there is no slurry in that area. The system is highly intelligent, requires no additional manual control, and is convenient and fast.
[0040] Preferably, the automatic material leveling and obstacle avoidance component 5 further includes a pressing telescopic rod 506 and a pressing plate 507. The pressing telescopic rod 506 is fixedly installed on the bottom side of the suspension frame 501. The pressing plate 507 is connected to the telescopic end of the pressing telescopic rod 506. The height of the pressing plate 507 is controlled by the pressing telescopic rod 506, so that the pressing plate 507 can press the slurry, making the unevenly distributed slurry more uniform, so that the slurry can be applied more evenly.
[0041] Furthermore, the curved wall reinforcement mechanism 6 includes an mounting plate 601 and a mounting side plate 602. The mounting plate 601 is an L-shaped plate, with one top end of the mounting plate 601 welded to the bottom of the lifting platform 3. The mounting side plate 602 is welded to one side of the bottom of the mounting plate 601. The horizontal movement control telescopic rod 603 is fixedly installed on the side wall of the mounting side plate 602, and the curved coating plate 604 is fixedly installed on the telescopic end of the horizontal movement control telescopic rod 603.
[0042] Furthermore, the number of both the horizontal movement control telescopic rod 603 and the arc-shaped coating plate 604 is preferably three. The three arc-shaped coating plates 604 are respectively connected to the telescopic ends of the three horizontal movement control telescopic rods 603, and the curvature of the three arc-shaped coating plates 604 is different. The extension and retraction of each arc-shaped coating plate 604 is controlled by the horizontal movement control telescopic rod 603. The extension of the three different arc-shaped coating plates 604 is controlled according to the curvature of the outer wall surface, so that the arc-shaped coating plates 604 can better match the curvature of the outer wall surface and be used for effective reinforcement and pressing of the plaster.
[0043] Working Principle: Other equipment is mounted on the fixed base 1. The height of the lifting platform 3 is adjusted via the lifting control frame 2, allowing the lifting platform 3 to move up and down, carrying plaster, a variable-form application component 4, an automatic material leveling and obstacle avoidance component 5, and a curved wall reinforcement mechanism 6. This allows for plastering on the building's exterior wall. In actual use, the variable-form application component 4 is used to pile up the plaster, pushing it towards one side of the wall as it rises to achieve basic plastering functionality. The variable-form application component 4 then applies the plaster, and the plaster shape is adjustable, allowing for application even on curved exterior walls. It can effectively adapt to its shape, so that the plastering edge of the variable form coating component 4 matches the curved exterior wall better, ensuring the plastering effect while improving plastering efficiency. The vision camera 502 collects information on the exterior wall surface. When encountering a large opening, that is, the reserved groove of the exterior wall, the blocking control telescopic rod 504 extends and the blocking plate 505 descends, thereby automatically cutting off the slurry on the rotating feeding platform 401 in advance, so that when the rotating feeding platform 401 moves to the reserved groove, there is no slurry in that part. The degree of intelligence is high, no additional manual control is required, and it is convenient and fast.
