Description

Technical Field

[0001] This invention relates to the technical field of wall painting, and in particular to an exterior wall painting device. Background Technology

[0002] Exterior wall painting refers to the process of applying a layer of paint or plaster to the surface of a building's exterior walls. Its purpose is to beautify the building's appearance, improve its weather resistance, provide waterproofing and moisture protection, and add a protective layer to the building structure. Before exterior wall painting, the wall surface must be thoroughly prepared, including cleaning away dust, dirt, and old coatings to ensure a smooth and crack-free surface. For areas with cracks or depressions, a base treatment is required, which can be done by filling with repair plaster or other repair materials to make the wall surface smoother.

[0003] In related technologies, traditional exterior wall painting requires workers to wear safety ropes and suspend themselves on the exterior wall to carry paint buckets. However, most modern buildings are high-rises, which adds more challenges and dangers to exterior wall painting. Therefore, some construction companies use suspended platforms to ensure the safety of their workers. Workers stand in the suspended platform and use brushes to paint the exterior walls of the building. However, this manual painting method is inefficient and the workers' workload is high, which affects the construction efficiency and is not suitable for practical use. Therefore, those skilled in the art provide an exterior wall painting device to solve the problems mentioned in the background technology. Summary of the Invention

[0004] In order to address the problems of low efficiency and high labor intensity of manual painting methods described in the background art, which affect construction efficiency, the present invention provides an exterior wall painting device.

[0005] The exterior wall painting device provided in this application adopts the following technical solution: An exterior wall painting device includes a painting basket, a drive roller and a connecting roller bolted to one side of the painting basket, a transmission adjustment assembly being engaged through the painting basket on one side of the drive roller, the lower surface of the transmission adjustment assembly being bolted to the bottom of the inner wall of the painting basket, a transmission assembly rotatably connected to the painting basket, one end of the transmission assembly being movably connected to the transmission adjustment assembly, a plurality of painting assemblies, each located on one side of the transmission assembly, a mechanical drive assembly located on the painting basket and movably connected to the transmission adjustment assembly, and a cleaning assembly located between the drive roller and the connecting roller, used for cleaning the wall surface. The drive roller includes a rectangular frame mounting plate bolted to one side of the painting basket. A first connecting ear plate is symmetrically fixed to one side of the rectangular frame mounting plate, and a second connecting ear plate is fixedly fixed to the other side of the rectangular frame mounting plate. A first shaft is rotatably connected inside the symmetrically arranged first connecting ear plates. One end of the first shaft is fixedly connected to one end of the cleaning component. A rolling wheel and a first gear are fixedly connected to the outer wall of the first shaft. A first toothed belt is driven to the outer wall of the first gear. A second gear is driven to the inner wall of the end of the first toothed belt away from the first gear. One side of the second gear is rotatably connected to the second connecting ear plate. The inner wall of the side of the second gear away from the second connecting ear plate is engaged with the transmission adjustment component. The transmission adjustment assembly includes an adjustment head that engages with the second gear. A connecting transmission rod is slidably connected to the inner wall of the adjustment head. A first limiting block is symmetrically fixedly connected to the outer wall of one end of the connecting transmission rod located on the inner wall of the adjustment head. The first limiting block is slidably connected to the inner wall of the adjustment head. A support frame is rotatably connected to the outer wall of the connecting transmission rod. The lower surface of the support frame is bolted to the bottom of the inner wall of the painting basket. A seventh gear is fixedly connected to the outer wall of the connecting transmission rod away from the adjustment head. A fourth toothed belt is driven to the outer wall of the seventh gear. An eighth gear is semi-cross-driven to the inner wall of the fourth toothed belt away from the seventh gear. The inner wall of the eighth gear is fixedly connected to the transmission assembly. A ninth gear is rotatably connected to the outer wall of the connecting transmission rod. The support frame is located between the seventh gear and the ninth gear. The outer wall of the ninth gear meshes with the mechanical drive assembly.

[0006] By adopting the above technical solution, the painting basket is suspended outside the wall by a crane. The paint liquid is delivered to several spray painting components by a pump. The spray painting components then replace manual labor to spray the paint liquid onto the exterior wall. When the painting basket moves down, the rollers roll along the wall and cooperate with the transmission adjustment components and transmission components to control the spray painting components to rotate while spraying, thereby improving the uniformity of paint application and construction efficiency. As the roller rolls along the wall, the first shaft drives the first gear to rotate. When the first gear rotates, the first toothed belt drives the second gear to rotate. The rotation of the second gear controls the operation of the transmission adjustment component. The adjustable head allows for engagement with either the second or ninth gear. As the adjustable head rotates, it is limited by the first limit block, causing the connecting transmission rod to rotate. When the connecting transmission rod rotates, the seventh gear, the fourth toothed belt, and the eighth gear engage to control the operation of the transmission assembly. Preferably, a dust extraction port is provided on one side of the painting basket, the dust extraction port is located above the cleaning component, a connecting channel is provided inside the painting basket that communicates with the dust extraction port, a vacuum cleaner is provided inside the painting basket, and the vacuum cleaner is connected to the connecting channel.

[0007] By adopting the above technical solution, when the vacuum cleaner is started, the connecting channel can control the suction of dust cleaned by the cleaning components from the dust inlet, which can enhance the cleaning effect on the wall.

[0011] By adopting the above technical solution, the symmetrically arranged painting basket, in conjunction with the drive roller and connecting roller, can prevent the painting basket from directly or obliquely sticking to the wall. When the painting assembly is in use, the partition plate and protective plate can provide a certain degree of protection for the spraying area.

[0012] Preferably, the adjusting head includes a cylindrical portion, one end of the connecting transmission rod is slidably connected to the inner wall of the cylindrical portion, and two second limiting blocks are symmetrically fixedly connected to the outer walls of both ends of the cylindrical portion. The second limiting block of the cylindrical portion near the second gear is located inside the second gear. A T-shaped moving block is symmetrically slidably connected to the cylindrical portion.

The second connecting strip passes through the interior of the spring. The lower end of the spring is elastically connected to the inner wall of the cylindrical portion.

[0013] By adopting the above technical solution, when the second limiting block at one end is located inside the second gear, it can engage with the second gear through the cooperation of the triangular locking block and the spring, and can be driven by the second gear. When it is necessary to adjust the position of the cylindrical part, the operator moves the T-shaped moving block away from the second gear, and then, through the cooperation of the first connecting strip, the straight corner code and the second connecting strip, the triangular locking block can be pulled away from the engagement part of the second gear, and the cylindrical part can be controlled to move.

[0014] Preferably, the transmission assembly includes a third shaft rotatably connected to the painting basket, the outer wall of the third shaft being fixedly connected to the inner wall of the eighth gear, a tenth gear being fixedly connected to the outer wall of the end of the third shaft away from the painting basket, a fifth toothed belt being drivenly connected to the outer wall of the tenth gear, and several eleventh gears being drivenly connected evenly to the inner wall of the fifth toothed belt, the several eleventh gears being horizontally arranged with the tenth gear, and the inner wall of the eleventh gear being fixedly connected to the outer wall of the painting assembly.

[0015] By adopting the above technical solution, when the third shaft rotates, the tenth gear and the fifth gear belt can cooperate to control the rotation of several eleventh gears, and the rotation of the eleventh gears can control the rotation of the painting assembly.

[0016] Preferably, the mechanical drive assembly includes a motor bolted to one side of the painting basket, the output end of the motor being fixedly connected to a fourth shaft through the painting basket, and a transmission gear being fixedly connected to the end of the fourth shaft away from the motor, the outer wall of the transmission gear meshing with the outer wall of the ninth gear.

[0017] By adopting the above technical solution, the starter motor can control the transmission gear to rotate through the fourth shaft, and when the transmission gear rotates, it can control the ninth gear meshing with it to rotate.

[0018] Preferably, the reinforced cleaning component includes a second shaft fixedly connected to the inner wall of the fourth gear, one end of the second shaft being rotatably connected to the outer wall of the painting basket, a fifth gear being fixedly connected to the outer wall of the second shaft near the painting basket, a third toothed belt being driven by the fifth gear, several sixth gears being uniformly driven by the outer wall of the third toothed belt, a connecting rod being fixedly connected to the inner wall of the sixth gear, one end of the connecting rod being rotatably connected to the outer wall of the painting basket, and a cleaning plate being fixedly connected to the other end of both the second shaft and the connecting rod.

[0019] By adopting the above technical solution, the rotation of the second shaft can be controlled by the rotating fourth gear. When the second shaft rotates, it cooperates with the fifth gear, the third toothed belt 3063 and several connecting rods to control the rotation of several connecting rods. The rotation of several connecting rods and the second shaft can control the rotation of several cleaning plates to scrape and clean the wall surface.

[0020] Preferably, the painting assembly includes a mounting tube fixedly connected to the inner wall of the eleventh gear. The end of the mounting tube away from the eleventh gear passes through the painting basket and the two are rotatably connected. A connecting straight pipe is fixedly connected to the inner wall of the mounting tube. A connecting inclined pipe is fixedly connected to one end of the connecting straight pipe. A paint spray head is fixedly connected to the end of the connecting inclined pipe away from the connecting straight pipe. A delivery hose is connected to the end of the mounting tube away from the paint spray head through a rotary joint.

[0021] By adopting the above technical solution, the installation position of the connecting straight pipe can be restricted by the installation pipe, and a connecting inclined pipe is fixedly connected to one end of the connecting straight pipe. When rotating, the paint spray head can spray in a circular motion through the connecting inclined pipe, thereby enhancing the uniformity of spraying.

[0022] In summary, the present invention has the following beneficial technical effects: 1. This exterior wall painting device suspends a painting basket outside the wall using a crane. A pump delivers paint liquid to several spray painting components, which then spray the paint liquid onto the exterior wall. As the painting basket descends, drive rollers roll along the wall. By cooperating with the drive rollers, transmission adjustment components, and transmission components, the spray painting components can be controlled to rotate while spraying, thereby improving the uniformity of paint application and construction efficiency, and saving manpower. Furthermore, when painting irregularly shaped exterior walls, the position of the transmission adjustment components can be adjusted, driven by a mechanical drive component, enhancing the practicality of this application. 2. This exterior wall painting device, while the drive roller and connecting roller are rolling, can drive the cleaning brush roller to rotate and scrape the wall surface through the connecting shaft. Through the cooperation of the connecting shaft, the second toothed belt and the fourth gear, the second shaft can be controlled to rotate. When the second shaft rotates, through the cooperation of the fifth gear, the third toothed belt 3063 and several connecting rods, several connecting rods can be controlled to rotate. Through the rotation of several connecting rods and the second shaft, several cleaning plates can be controlled to rotate and scrape the wall surface, thus facilitating subsequent spray painting. 3. This exterior wall painting device, through the symmetrical arrangement of the painting basket, drive rollers, and connecting rollers, can prevent the painting basket from directly or obliquely sticking to the wall surface. The partition plate is located above the dust extraction port, which can prevent dust extraction from affecting the painting when the painting assembly is in use. The protective plate is located above the painting assembly, which can prevent the paint from drifting upwards and affecting the activities of personnel inside the painting basket when the painting assembly is in use, thereby enhancing the safety of painting.

[0025] The following is in conjunction with the appendix Figure 1-9 The present invention will be described in further detail below. Example

[0026] This invention discloses an exterior wall painting device. (Refer to...) Figure 1 and Figure 2 The exterior wall painting device includes a painting basket 1. The painting basket 1 needs to be suspended outside the wall by a crane during use. The interior of the painting basket 1 can be used for construction workers to stand, which facilitates the painting work or inspection of the painted wall. One side of the painting basket 1 is connected to a drive roller 2 and a connecting roller 4 by bolts. When the painting basket 1 is suspended outside the wall by the crane and moves downward, the drive roller 2 and the connecting roller 4 can limit the distance between the painting basket 1 and the wall, which can prevent the painting basket 1 from directly sticking to the wall. One side of the drive roller 2 passes through the painting basket 1 and is engaged with a transmission adjustment component 5. When the painting basket 1 moves, the drive roller 2 rolls against the wall, which can drive the transmission adjustment component 5. The lower surface of the transmission adjustment component 5 is connected to the bottom of the inner wall of the painting basket 1 by bolts. In a further preferred embodiment of the invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the drive roller 2 includes a rectangular frame mounting plate 201 bolted to one side of the painting basket 1. The rectangular frame mounting plate 201, in conjunction with the bolts, can be mounted on one side of the painting basket 1. A first connecting ear plate 202 is symmetrically fixedly connected to one side of the rectangular frame mounting plate 201, and a second connecting ear plate 208 is fixedly connected to the other side. The rectangular frame mounting plate 201 restricts the installation positions of the symmetrically arranged first connecting ear plate 202 and the individual second connecting ear plate 208. A first shaft 203 is rotatably connected inside the symmetrically arranged first connecting ear plate 202. One end of the first shaft 203 is fixedly connected to one end of the cleaning component 3. A rolling wheel 204 and a first gear 205 are fixedly connected to the outer wall of the first shaft 203. The symmetrically arranged first connecting ear plate 202 and the first shaft 203 cooperate... The system can limit the installation position of the rolling wheel 204 and the first gear 205. The outer wall of the rolling wheel 204 is a non-slip rubber pad, so that when the rolling wheel 204 rolls along the wall, the first shaft 203 can drive the first gear 205 to rotate. The outer wall of the first gear 205 is connected to the first toothed belt 206. The inner wall of the first toothed belt 206 away from the first gear 205 is connected to the second gear 207. One side of the second gear 207 is rotatably connected to the second connecting ear plate 208. When the first gear 205 rotates, the first toothed belt 206 can drive the second gear 207 rotatably connected to one side of the second connecting ear plate 208 to rotate. The inner wall of the second gear 207 away from the second connecting ear plate 208 is engaged with the transmission adjustment component 5, so the rotation of the second gear 207 can control the use of the transmission adjustment component 5.

[0027] In a further preferred embodiment of the invention, such as Figure 2 , Figure 3 and Figure 4As shown, the transmission adjustment assembly 5 includes an adjustment head 501 that engages with the second gear 207. A connecting transmission rod 502 is slidably connected to the inner wall of the adjustment head 501. A first limiting block 503 is symmetrically fixed to the outer wall of one end of the connecting transmission rod 502 located on the inner wall of the adjustment head 501. The first limiting block 503 is slidably connected to the inner wall of the adjustment head 501. A support frame 504 is rotatably connected to the outer wall of the connecting transmission rod 502. The contact surface between the support frame 504 and the connecting transmission rod 502 is rotatably connected by a bearing. The lower surface of the support frame 504 is connected to the bottom of the inner wall of the painting basket 1 by a screw. A bolt connection is made, and a seventh gear 505 is fixedly connected to the outer wall of the end of the connecting transmission rod 502 away from the adjusting head 501. A fourth toothed belt 506 is driven to the outer wall of the seventh gear 505. An eighth gear 507 is semi-cross-driven to the inner wall of the end of the fourth toothed belt 506 away from the seventh gear 505. The inner wall of the eighth gear 507 is fixedly connected to the transmission assembly 6. A ninth gear 508 is rotatably connected to the outer wall of the connecting transmission rod 502. A support frame 504 is located between the seventh gear 505 and the ninth gear 508. The outer wall of the ninth gear 508 meshes with the mechanical drive assembly 8.

[0028] In this embodiment, the adjusting head 501 can be adjusted to engage with the second gear 207 or the ninth gear 508. When the adjusting head 501 is engaged with the second gear 207, the rotation of the second gear 207 controls the rotation of the adjusting head 501. Simultaneously, the adjusting head 501 rotates under the limitation of the symmetrically arranged first limiting block 503, which drives the connecting transmission rod 502 to rotate. The rotation of the connecting transmission rod 502 controls the rotation of the seventh gear 505. When the seventh gear 505 rotates, it engages with the eighth gear 507 through the fourth toothed belt 506, which controls the use of the transmission assembly 6. A support frame 504 is rotatably connected to the outer wall of the connecting transmission rod 502. The support frame 504 supports and limits the installation position of the transmission adjusting assembly 5. When the adjusting head 501 is engaged with the ninth gear 508, it can be driven by the mechanical drive assembly 8.

[0029] In a further preferred embodiment of the invention, such as Figure 4 , Figure 5 and Figure 6As shown, the adjusting head 501 includes a cylindrical portion 5011. One end of the connecting transmission rod 502 is slidably connected to the inner wall of the cylindrical portion 5011. An installation groove for mounting the connecting transmission rod 502 and a sliding groove for limiting the movement of the first limiting block 503 are provided inside the cylindrical portion 5011. Second limiting blocks 5012 are symmetrically fixedly connected to the outer walls of both ends of the cylindrical portion 5011. These symmetrically fixed second limiting blocks 5012 are located on the outer walls of both ends of the cylindrical portion 5011, allowing them to be positioned inside the second gear 207 or the ninth gear 508 respectively during adjustment. The second limiting block 5012 near the end of the cylindrical portion 5011 closest to the second gear 207 is located inside the second gear 207. A T-shaped sliding joint is symmetrically slidably connected to the cylindrical portion 5011. Block 5013, a T-shaped moving block 5013 is fixedly connected to a first connecting strip 5014 on the side near the second limiting block 5012. A letter angle bracket 5015 is hinged to one end of the first connecting strip 5014 near the second limiting block 5012. A second connecting strip 5016 is hinged to the other end of the letter angle bracket 5015 away from the first connecting strip 5014. A triangular locking block 5017 is fixedly connected to the upper end face of the second connecting strip 5016. The triangular locking block 5017 is slidably connected to the second limiting block 5012. The outer wall of the triangular locking block 5017 is engaged with the inner wall of the second gear 207. A spring 5018 is fixedly connected to the lower surface of the triangular locking block 5017. The second connecting strip 5016 passes through the interior of the spring 5018. The lower end face of the spring 5018 is elastically connected to the inner wall of the cylindrical part 5011. When the second limiting block 5012 at one end is located inside the second gear 207, it can engage with the second gear 207 through the cooperation of the triangular locking block 5017 and the spring 5018, thereby enabling it to be driven by the second gear 207. When it is necessary to adjust the position of the cylindrical part 5011, the user can move the T-shaped moving block 5013 away from the second gear 207. When the T-shaped moving block 5013 moves, it can be driven by the cooperation of the first connecting strip 5014, the straight corner bracket 5015 and the second connecting strip 5016. Pulling the triangular locking block 5017 to move it disengages it from the engagement part of the second gear 207, thereby controlling the movement of the cylindrical part 5011. When the cylindrical part 5011 moves away from the second gear 207, the second limiting block 5012 at the other end of the cylindrical part 5011 can be located inside the ninth gear 508. At this time, the triangular locking block 5017 located in the second limiting block 5012 at the other end can engage with the ninth gear 508, thereby enabling the ninth gear 508 to drive the mechanical drive assembly 8.

[0030] Reference Figure 1 , Figure 2 and Figure 7The transmission component 6 is rotatably connected to the painting basket 1. One end of the transmission component 6 is movably connected to the transmission adjustment component 5. There are several spray painting components 7, all of which are located on one side of the transmission component 6. When the transmission adjustment component 5 is driven to move, the transmission component 6 can simultaneously control the rotation of several spray painting components 7. Paint liquid is connected to one end of the spray painting component 7 through the pump body, so that the spray painting component 7 can spray paint onto the wall while rotating. The method of spraying paint by rotating the spray painting component 7 can improve the uniformity of paint application. The transmission assembly 6 includes a third shaft 601 rotatably connected to the painting basket 1. The outer wall of the third shaft 601 is fixedly connected to the inner wall of the eighth gear 507. The rotation of the eighth gear 507 can control the rotation of the third shaft 601. A tenth gear 602 is fixedly connected to the outer wall of the end of the third shaft 601 away from the painting basket 1. A fifth toothed belt 603 is drivenly connected to the outer wall of the tenth gear 602. Several eleventh gears 604 are evenly drivenly connected to the inner wall of the fifth toothed belt 603. When the third shaft 601 rotates, the tenth gear 602 and the fifth toothed belt 603 cooperate to control the rotation of several eleventh gears 604. The several eleventh gears 604 and the tenth gear 602 are horizontally arranged. The inner wall of the eleventh gear 604 is fixedly connected to the outer wall of the painting assembly 7. The number of eleventh gears 604 matches the number of painting assemblies 7, so that the rotation of the eleventh gears 604 can control the rotation of the painting assembly 7. The painting assembly 7 includes a mounting tube 701 fixedly connected to the inner wall of the eleventh gear 604. The end of the mounting tube 701 away from the eleventh gear 604 passes through the painting basket 1, and the two are rotatably connected. This rotatable connection between the mounting tube 701 and the painting basket 1 restricts the position of the eleventh gear 604 when it rotates. A straight connecting tube 702 is fixedly connected to the inner wall of the mounting tube 701, and a connecting inclined tube 703 is fixedly connected to one end of the straight connecting tube 702. For inclined installation, a paint spray head 704 is fixedly connected to the end of the inclined pipe 703 away from the straight pipe 702. When rotated, the paint spray head 704 can spray in a circular motion, which can enhance the uniformity of spraying. The end of the installation pipe 701 away from the paint spray head 704 is connected to a delivery hose 705 through a rotary joint. The wall paint can be delivered into the interior of the installation pipe 701 through the delivery hose 705. The rotary joint can maintain the transfer of liquid between the two relatively rotating parts without hindering their relative rotational movement.

[0031] In a further preferred embodiment of the invention, such as Figure 1 and Figure 2As shown, the mechanical drive assembly 8 is mounted on the painting basket 1 and movably connected to the transmission adjustment assembly 5. When painting an irregularly shaped exterior wall, the position of the transmission adjustment assembly 5 can be adjusted to drive the mechanical drive assembly 8, thereby enhancing the practicality of the application. The mechanical drive assembly 8 includes a motor 801 bolted to one side of the painting basket 1. The output end of the motor 801 is fixedly connected to a fourth shaft 802 through the painting basket 1. A transmission gear 803 is fixedly connected to the end of the fourth shaft 802 away from the motor 801. Starting the motor 801 can control the transmission gear 803 to rotate through the fourth shaft 802. The outer wall of the transmission gear 803 meshes with the outer wall of the ninth gear 508. When the transmission gear 803 rotates, it can control the rotation of the ninth gear 508. When the adjustment head 501 is engaged with the ninth gear 508, the drive can be controlled by the rotation of the ninth gear 508.

[0032] Reference Figure 1 and Figure 8 The cleaning component 3 is located between the drive roller 2 and the connecting roller 4 and is used to clean the wall surface. The rotation of the drive roller 2 and the connecting roller 4 can control the rotation of the cleaning component 3 to perform a certain amount of scraping and cleaning on the wall surface, thereby improving the painting effect of the exterior wall. In use, the painting component 7 is mainly used to replace manual painting of the exterior wall. While the painting component 7 is spraying, the drive roller 2, the transmission adjustment component 5 and the transmission component 6 can be used to control the painting component 7 to rotate while spraying, thereby improving the uniformity of the paint and the construction efficiency, making the application more suitable for practical use.

A connecting channel 10 is provided inside the painting basket 1, which is connected to the dust extraction port 9. A vacuum cleaner 11 is installed inside the painting basket 1 and is connected to the connecting channel 10. The vacuum cleaner 11 can be activated when the painting basket 1 moves down. When the vacuum cleaner 11 is activated, the dust cleaned by the cleaning component 3 can be sucked out from the dust extraction port 9 through the connecting channel 10, thereby enhancing the cleaning effect on the wall and facilitating subsequent spray painting. Example

[0034] This embodiment is an improvement based on embodiment 2, please refer to the following for details. Figure 1As shown, one side of the painting basket 1 is symmetrically connected with limiting rollers 12 by bolts. The symmetrically arranged limiting rollers 12 are all located above the dust extraction port 9 and in the upper middle part of one side of the painting basket 1. The symmetrical arrangement of the painting basket 1 with the drive roller 2 and connecting roller 4 can prevent the painting basket 1 from directly or obliquely sticking to the wall. One side of the painting basket 1 is fixedly connected with a partition plate 13 and a protective plate 14. There is a certain gap between the partition plate 13 and the protective plate 14 and the wall. When the painting assembly 7 is in use, the partition plate 13 and the protective plate 14 can play a certain protective role for the spraying area. The partition plate 13 is located between the limiting roller 12 and the painting assembly 7, which can prevent the dust extraction from affecting the painting. The protective plate 14 is located above the painting assembly 7, which can prevent the paint from drifting upwards and affecting the activities of the personnel inside the painting basket 1.

[0035] The implementation principle of the exterior wall painting device in this embodiment of the invention is as follows: In use, the painting basket 1 is suspended from the outside of the wall by a crane. The distance between the painting basket 1 and the wall is limited by the drive roller 2 and the connecting roller 4. The paint liquid is delivered to several spray painting components 7 by the pump body. The paint liquid can then be sprayed onto the exterior wall by the spray painting components 7. When the painting basket 1 moves down, the drive roller 2 rolls along the wall. By cooperating with the transmission adjustment component 5 and the transmission component 6, the drive roller 2 can control the spray painting components 7 to rotate while spraying, thereby improving the uniformity of paint application and construction efficiency. While the drive roller 2 and the connecting roller 4 are rolling, they can also drive the cleaning component 3 to move. The movement of the cleaning component 3 can perform a certain amount of scraping and cleaning on the wall, thereby improving the painting effect of the exterior wall and making this application more conducive to practical use.
