Description

Technical Field

[0001] This utility model relates to the technical field of exterior wall spraying equipment, and in particular to an exterior wall spraying device for building construction. Background Technology

[0002] Currently, exterior wall painting of buildings mainly relies on manual hand-held spray guns or simple mechanical devices. Traditional spraying methods have many drawbacks: First, working at heights poses significant safety risks, requiring workers to erect scaffolding or use suspended platforms, which is not only inefficient but also prone to falls; second, the quality of manual spraying is difficult to guarantee, easily resulting in uneven coating thickness, missed areas, or runs. With the construction industry's increasing demands for construction efficiency, quality, and environmental protection, there is a need for an exterior wall spraying device for buildings.

[0003] Utility model patent application number 202121880506.8 discloses a wall spraying device for building construction. This device, through a moving mechanism, uses a servo motor to rotate a lead screw, which in turn moves two lead screw pairs, thereby moving a lifting hydraulic press to control the horizontal position of the spray. A vertical adjustment mechanism uses a rotary motor to rotate a rotating shaft, which in turn rotates a rotating plate, which in turn rotates a movable rod, which in turn rotates a connecting rod, which in turn moves a slider up and down on a groove, causing the spray pipe and nozzle to reciprocate vertically, facilitating spraying while moving. A stirring device uses a drive motor to rotate a stirring rod, which in turn rotates a stirring blade to mix the paint in the storage tank evenly, ensuring uniform spraying, reducing manual labor intensity, and increasing work efficiency. However, in this design, if an uneven wall surface cannot be sanded in time, the spraying may be uneven, affecting the quality of the exterior wall spraying.

[0004] Therefore, it is necessary to provide an exterior wall spraying device for building construction to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an exterior wall spraying device for building construction.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An exterior wall spraying device for building construction includes: a trolley, a bracket at one end of the trolley, a mounting frame between the brackets, a second telescopic rod between the two ends of the bottom of the mounting frame and the trolley, a grinder at the front of the mounting frame, a fixed rod inside the mounting frame (the fixed rod is inverted L-shaped), one end of the fixed rod being fixedly connected to the grinder, a suction pipe at the bottom of the fixed rod, a dust collection trough at the front end of the suction pipe, a collection box at the bottom end of the suction pipe, sliders between the two sides of the fixed rod and the mounting frame, grooves on the outer sides of the sliders, a third telescopic rod inside the mounting frame near the rear of the fixed rod, a spray pipe at the front of the upper end of the mounting frame, a discharge pipe at the rear of the spray pipe, and a paint tank at the bottom of the discharge pipe.

[0008] Preferably, connecting plates are provided between the two sides of the spray pipe and the mounting bracket, positioning plates are provided between the connecting plates, and a set of first telescopic rods are provided on the positioning plates.

[0009] Preferably, both the discharge pipe and the suction pipe are equipped with telescopic pipes, and an air pump is installed at the bottom of the suction pipe near the top of the collection box.

[0010] Preferably, the spraying pipe has limit grooves at both ends and inside the connecting plate, and a limit rod is provided inside the limit groove. A set of springs is provided inside the limit groove on the side near the limit rod. An adapter is provided between the spraying pipe and the discharge pipe.

[0011] Preferably, a stirring shaft is provided inside the paint tank, and a motor is provided above the paint tank near the stirring shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) This utility model effectively solves the problem of incomplete base treatment in traditional exterior wall construction by using an integrated grinding and dust removal system. The grinding machine can adapt to the protruding parts of the wall surface through the precise control of the third telescopic rod, ensuring uniform grinding force. When the air pump is started, the dust suction pipe can continuously discharge the debris collected in the dust collection tank, preventing the accumulation of debris. It can also absorb the dust floating in the air, improving the treatment effect of debris. This avoids secondary pollution and creates a clean working surface for subsequent spraying.

[0014] (2) This utility model adopts a quick disassembly structure with a limit rod and a spring, which shortens the replacement time of the spray tube. During operation, only one hand is needed to squeeze the limit rod to both sides to release the constraint of the connecting plate. With the screwing design of the adapter, the entire spray tube can be quickly disassembled, so as to support the replacement of different nozzles (fan-shaped, cone-shaped, etc.) to adapt to different coatings (latex paint, stone paint, fluorocarbon paint), further improving the practicality of the device.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0022] Example 1

[0023] like Figure 1-5As shown, the exterior wall spraying device for building construction provided by this utility model includes: a trolley 1, which facilitates the movement of the device to a designated position; a bracket 3 is provided at one end of the trolley 1; a mounting frame 4 is provided between the brackets 3; the mounting frame 4 and the brackets 3 are slidably connected; and a second telescopic rod 15 is provided between the two ends of the bottom of the mounting frame 4 and the trolley 1. The second telescopic rod 15 can be selected as an electric push rod, a cylinder, or a hydraulic cylinder as needed. In use, the second telescopic rod 15 can push the mounting frame 4 to move up and down between the brackets 3, thereby adjusting the height of the device and performing up and down spraying. The front of the mounting frame 4... A sander 5 is installed on the side. The sander 5 can be used to sand down any protruding parts of the wall surface before exterior wall painting, smoothing the surface before spraying. This greatly improves the painting effect and prevents uneven spraying. The mounting bracket 4 has a fixing rod 18 inside. The fixing rod 18 is inverted L-shaped, and one end of the fixing rod 18 is fixedly connected to the sander 5 to secure it. A dust suction pipe 7 is installed at the bottom of the fixing rod 18, and a dust collection groove 6 is installed at the front end of the dust suction pipe 7. This allows the sander 5 to effectively collect the debris generated during sanding and to draw out the dust. The ash pipe 5 continuously discharges the debris collected in the ash collection trough 6, preventing debris accumulation. It can also absorb dust floating in the air, improving the debris treatment effect. A collection box 8 is provided at the bottom of the ash suction pipe 7, allowing the debris sucked up by the ash suction pipe 5 to be guided into the collection box 8 for unified treatment. Slider blocks 20 are provided between the two sides of the fixed rod 18 and the mounting frame 4. A sliding groove 19 is provided on the outer side of the slider 20. A third telescopic rod 21 is provided inside the mounting frame 4 near the rear side of the fixed rod 18. The third telescopic rod 21 can be selected as an electric push rod, a pneumatic cylinder, or a hydraulic cylinder as needed. During use, the third telescopic rod 21 can be activated. The telescopic rod 21 and the third telescopic rod 21 can simultaneously push the sander 5 and the dust collection tank 6 to move, allowing the sander 5 to closely follow the protruding parts of the wall and move as the protruding parts are continuously ground smooth, further improving the sanding effect of the device. When spraying is performed later, the sander 5 can retract backward. The front side of the upper end of the mounting frame 4 is provided with a spray pipe 9, and multiple nozzles are installed on the spray pipe 9. The rear side of the spray pipe 9 is provided with a discharge pipe 12, and the bottom of the discharge pipe 12 is provided with a paint tank 2. After sanding is completed, the paint in the paint tank 2 can be discharged from the discharge pipe 12 and sprayed out from the spray pipe 9 to achieve the spraying of the exterior wall.

[0024] Example 2

[0025] like Figure 1-2As shown, connecting plates 11 are provided on both sides of the spray pipe 9 and between the mounting bracket 4. A positioning plate 26 is provided between the connecting plates 11. The connecting plates 11 are slidably connected to the bracket 3 and the positioning plate 26. A set of first telescopic rods 10 is provided on the positioning plate 26. The third telescopic rod 21 can be selected as an electric push rod, a cylinder, or a hydraulic cylinder as needed. The output shaft of the first telescopic rod 10 is connected to the spray pipe 9. When spraying, the first telescopic rod 10 can be activated to drive the spray pipe 9 out, which makes it more convenient to spray the exterior wall.

[0026] Example 3

[0027] like Figure 1-3 As shown, both the discharge pipe 12 and the suction pipe 7 are equipped with telescopic pipes 13, so that when the spray pipe 9 and the dust collection trough 6 move, the telescopic pipe 13 can be stretched or retracted together to ensure the effectiveness of the device. The bottom of the suction pipe 7 is equipped with an air pump 16 near the upper part of the collection box 8. When sanding, the air pump 16 can be started to quickly collect the debris inside the dust collection trough 6 and the floating dust outside, ensuring the sanding and spraying quality of the wall. In addition, a paint pump is installed on the discharge pipe 12 to facilitate the extraction and transportation of the paint inside.

[0028] Example 4

[0029] like Figure 2 and Figure 5 As shown, both ends of the spray pipe 9 and the interior of the connecting plate 11 are provided with limiting grooves 23. A limiting rod 22 is provided inside the limiting groove 23. The front end of the limiting rod 22 passes through the limiting groove 23 in the connecting plate 11. A set of springs 24 is provided inside the limiting groove 23 near the limiting rod 22. When the device needs to replace the nozzle, the limiting rod 22 can be pulled to squeeze the springs 24, pulling one end of the limiting rod 22 out of the limiting groove 23 in the connecting plate 11, realizing the quick disassembly of the spray pipe 9 and the connecting plate 11. This enables the replacement of different nozzles (fan-shaped, conical, etc.) to adapt to different coatings (latex paint, stone paint, fluorocarbon paint), further improving the practicality of the device. An adapter 17 is provided between the spray pipe 9 and the discharge pipe 12, which facilitates the rotation of the adapter 17 to realize the disassembly between the spray pipe 9 and the discharge pipe 12. Furthermore, the output shaft of the first telescopic rod 10 is connected to the spray pipe 9 by a socket, and it can be disassembled simply by pulling it outward.

[0030] Example 5

[0031] like Figure 1 and Figure 4As shown, a stirring shaft 25 is installed inside the paint tank 2. A motor 14 is installed above the paint tank 2 near the stirring shaft 25. In use, the motor 14 can be started to drive the stirring shaft 25 to rotate, so as to continuously stir the paint inside the paint tank 2, prevent the paint from settling, and improve the uniformity of the paint.

[0032] The working principle of the exterior wall spraying device for building construction provided by this utility model is as follows:

[0033] When using this device, first move it to the designated construction position using the trolley 1. Adjust the second telescopic rod 15 according to the wall height, and push the mounting frame 4 up and down along the bracket 3 to the appropriate height. Before spraying, start the third telescopic rod 21 to push the grinder 5 and dust collection tank 6 towards the wall. At the same time, start the grinder 5 to grind the protruding parts of the wall. During the grinding process, the air pump 16 continuously sucks up the debris and floating dust in the dust collection tank 6 through the suction pipe 7 and directs it into the collection box 8 for unified treatment, ensuring a clean working environment. After grinding is completed, the third telescopic rod 21 retracts to remove the grinder 5 from the wall, avoiding interference with subsequent spraying operations.

[0034] During spraying, the first telescopic rod 10 pushes the spray pipe 9 outward. The paint in the paint tank 2 is transported to the spray pipe 9 through the discharge pipe 12 and evenly sprayed onto the wall through the nozzle. The motor 14 above the paint tank 2 drives the stirring shaft 25 to continuously stir, preventing paint sedimentation and ensuring spraying quality. During the spraying process, the operator can adjust the second telescopic rod 15 as needed to move the mounting frame 4 up and down to achieve continuous spraying. The telescopic pipe 13 extends and retracts synchronously with the movement of the spray pipe 9 and the dust collection trough 6 to ensure unobstructed pipeline. If it is necessary to change the nozzle to adapt to different paints (such as stone paint or latex paint), the limit rod 22 can be pulled to compress the spring 24, causing it to disengage from the limit groove 23, and the spray pipe 9 can be quickly disassembled to replace the nozzle.

[0035] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
