[0001] The invention relates to the technical field of wall plastering, and in particular to an environmentally friendly outdoor wall plastering device. Background Art

[0002] Environmentally friendly outdoor wall plastering equipment is a highly efficient and environmentally friendly equipment specially used in building construction, which aims to improve the quality and efficiency of plastering work and reduce the impact on the environment during the construction process. This device is usually automated or semi-automated, which can greatly reduce labor costs, improve construction safety, and has significant advantages in environmental protection.

[0003] The existing outdoor wall plastering device usually moves to the outer wall of the building through a mobile vehicle, and then pushes the scraper up and down through a lifting device to smooth the mortar on the outer wall of the building. However, due to the limited moving height of the scraper, it is impossible to move to a high place to plaster the outer wall of a high-rise building. When plastering the outer wall of a high-rise building, it needs to be applied manually, which is inefficient and costly.

[0004] Therefore, an environmentally friendly outdoor wall plastering device has been developed that can be moved to a high place to plaster the exterior walls of high-rise buildings, improve the wall plastering efficiency, and reduce construction costs. Summary of the invention

[0005] In order to overcome the shortcomings of existing outdoor wall plastering devices that cannot be moved to a high place to plaster the exterior walls of high-rise buildings, and that plastering the exterior walls of high-rise buildings requires manual application, which is inefficient and costly, the present invention provides an environmentally friendly outdoor wall plastering device that can be moved to a high place to plaster the exterior walls of high-rise buildings, thereby improving the wall plastering efficiency and reducing the construction cost.

[0007] Optionally, the smearing mechanism includes a first motor, a connecting screw, a movable frame, a fixed plate, a connecting pipe, a first scraper and a second scraper. The first motor is connected to the upper left side of the connecting and fixing frame, and the connecting screw is rotatably connected to the front left side of the connecting and fixing frame. The output shaft of the first motor is connected to the connecting screw, and the movable frame is threadedly connected to the connecting screw. The right front part of the connecting and fixing frame is also slidably connected to the movable frame. A fixed plate is connected between the movable frames, a connecting pipe is connected to the middle of the fixed plate, the first scraper is connected to the lower part of the fixed plate, and the second scraper is connected to the upper part of the fixed plate. A rope is connected to the connecting bracket so that the connecting and fixing frame is located outside the outer wall of the building. The connecting and fixing frame is moved on the outer wall of the building by retracting and releasing the rope. When the connecting and fixing frame moves to the specified position, mortar is introduced into the connecting pipe so that the mortar is sprayed from the nozzle onto the outer wall of the building.

The first motor 30 is connected to the upper left side of the connecting and fixing frame 1, the connecting screw 31 is rotatably connected to the front left side of the connecting and fixing frame 1, the output shaft of the first motor 30 is connected to the connecting screw 31, the movable frame 32 is threadedly connected to the connecting screw 31, the movable frame 32 is also slidably connected to the right front part of the connecting and fixing frame 1, a fixed plate 33 is connected between the movable frames 32, a connecting pipe 34 is connected to the middle of the fixed plate 33, eight nozzles 35 are connected to the rear side of the connecting pipe 34, the first scraper 36 is connected to the lower part of the fixed plate 33, and the second scraper 37 is connected to the upper part of the fixed plate 33.

[0036] When using the present invention, first move the connecting and fixing frame 1 to the building outer wall that needs to be plastered, then connect the rope to the connecting bracket 2, so that the connecting and fixing frame 1 is located outside the building outer wall, and move the connecting and fixing frame 1 on the building outer wall by retracting and releasing the rope. When the connecting and fixing frame 1 moves to the specified position, mortar is introduced into the connecting pipe 34 so that the mortar is sprayed from the nozzle 35 onto the building outer wall. While the mortar is sprayed, start the first motor 30 to drive the connecting screw rod 31 to rotate, so that the moving frame 32 moves downward, and drives the fixing plate 33 to move downward, so that the first scraper 36 and the second scraper 37 smooth the mortar on the building outer wall, and the excess mortar falls into the first scraper 36, thereby achieving the effect of being able to move to a high place to plaster the outer wall of a high-rise building, improving the wall plastering efficiency, and reducing the construction cost.

[0037] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, it also includes an adsorption mechanism 4, which includes a reciprocating screw rod 40, a guide column 41, an extrusion column 42, a first spring 43, a movable connecting frame 44, a hollow column 45, a suction cup 46 and a connecting column 47.

After the moving frame 32 is separated from the squeezing column 42, the first spring 43 rebounds, causing the squeezing column 42 to reset. At this time, the squeezing column 42 does not trigger the guide column 41 to rotate. When the moving frame 32 moves upward and resets, the squeezing column 42 is pressed again, causing the reciprocating screw 40 to rotate, and the moving connecting frame 44 to reset, thereby causing the suction cup 46 to separate from the wall surface, and then the connecting frame 1 is moved to the next position for plastering.

[0040] The storage mechanism 5 of the device can be used to store mortar. The mortar is injected into the connecting barrel 50. When mortar needs to be introduced into the connecting pipe 34, the first connecting pump 51 is started to allow the mortar to enter the connecting pipe 34 from the first hose 52. After the excess mortar falls into the first scraper 36, the second connecting pump 53 is started to recover the mortar in the first scraper 36 into the connecting barrel 50 through the second hose 54, thereby storing the mortar and facilitating its movement to a higher place for plastering the wall.
