Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please refer to Figures 3 to 9 , Figure 3 This is a schematic diagram of the construction spraying equipment provided in the embodiments of this application from a third-party perspective; Figure 4 This is a schematic diagram of the construction spraying equipment provided in the embodiments of this application in the fourth direction; Figure 5 A partial structural diagram of the spraying equipment for construction provided in an embodiment of this application at the mixing equipment; Figure 6 This is a partial structural diagram of the construction spraying equipment provided in the embodiments of this application, including the lifting device, mounting base, sliding base, cleaning component, and spraying component.

[0032] Please refer to Figure 3 , Figure 4 and Figure 7 This application provides a spraying equipment for construction, including a mobile carrier 1, a spraying liquid storage device 2 for storing spraying liquid, and a spraying assembly 3 for spraying spraying liquid onto a target object; both the spraying liquid storage device 2 and the spraying assembly 3 are located on the mobile carrier 1 and are interconnected; the spraying assembly 3 includes a strip-shaped nozzle 301 and two nozzle sealing members 31, which are slidably installed along the length of the strip-shaped nozzle 301, and each nozzle sealing member 31 is connected to a sealing member driving device, and the two nozzle sealing members 31 move independently of each other.

[0033] In this spraying equipment, both the spraying liquid storage device 2 and the spraying assembly 3 are mounted on the mobile carrier 1. Operators can move the mobile carrier 1 within the work area, thereby moving the spraying liquid storage device 2 and the spraying assembly 3. The mobile carrier 1 can have motion characteristics; for example, it may be equipped with rollers, a drive device, or other components. Alternatively, the mobile carrier 1 can be a conventional mounting base, which operators can hold and move.

[0034] In this construction spraying equipment, the spraying liquid storage device 2 and the spraying component 3 are interconnected. In other words, the spraying component 3 is located at the outlet of the spraying liquid storage device 2. The spraying liquid storage device 2 can supply spraying liquid to the spraying component 3, and the spraying component 3 can spray the spraying liquid provided by the spraying liquid storage device 2 onto the target object, such as the road surface, the step surface, etc.

[0035] In this spraying equipment, the spraying component 3 has a strip-shaped nozzle 301 connected to two nozzle sealing members 31. These two nozzle sealing members 31 are slidably connected along the length of the strip-shaped nozzle 301. Either nozzle sealing member 31 can partially block the strip-shaped nozzle 301. Therefore, adjusting the position of the two nozzle sealing members 31 on the strip-shaped nozzle 301 can adjust the actual spraying size of the strip-shaped nozzle 301. The size, moving distance, and moving range of the nozzle sealing member 31 can all affect the actual spraying size of the strip-shaped nozzle 301. For example, the distance the nozzle sealing member 31 moves from the end of the strip-shaped nozzle 301 towards the middle determines the reduction in the actual spraying size of the strip-shaped nozzle 301 by that length.

[0036] When using this construction spraying equipment, the operator can adjust the actual spraying size of the strip nozzle 301 before moving the moving carrier 1, or adjust the actual spraying size of the strip nozzle 301 at any time during the movement of the moving carrier 1. The final spraying effect of the aforementioned strip nozzle 301 mainly depends on parameters such as the actual spraying size of the strip nozzle 301 and the movement range of the moving carrier 1. For example, when moving the moving carrier 1, the strip nozzle 301 maintains its original length L0. When the operator uses the moving carrier 1 to move the spraying component 3 a distance S1 along the width direction of the strip nozzle 301, the strip nozzle 301 can spray a rectangular pattern with a length of L0 and a width of S1 on the spraying surface, such as a road surface. Obviously, if the length of the strip nozzle 301, i.e., the actual spraying size, is changed when moving the moving carrier 1, the strip nozzle 301 can spray other patterns on the spraying surface, such as arrows or other characters on a road surface.

[0037] In summary, the construction spraying equipment provided in this application can use a moving carrier 1 to move the spraying component 3 and its strip nozzle 301 relative to the spraying surface. The length of the strip nozzle 301 can be flexibly adjusted using the nozzle sealing component 31 to achieve the spraying of patterns on the spraying surface. In this construction spraying equipment, the strip nozzle 301 is connected to two nozzle sealing components 31. These two nozzle sealing components 31 can move synchronously around the midpoint of the length of the strip nozzle 301, or they can move independently, thereby flexibly and conveniently spraying various symmetrical or asymmetrical patterns without having to repeatedly move the entire equipment to adjust the spraying pattern. This reduces the difficulty and workload of the operation, improves the operation effect, and enriches the spraying effect.

[0038] The construction spraying equipment provided in this application will be further described below with reference to the accompanying drawings and embodiments.

[0039] Please refer to Figure 3 , Figures 6 to 9In some embodiments, the spraying assembly 3 includes not only a strip nozzle 301 and a nozzle plug 31, but also a spray pipe 32 and a sleeve 33. Typically, one spray pipe 32 connects to two sleeves 33, and both sleeves 33 are fitted with the spray pipe 32. The strip nozzle 301 is located on the spray pipe 32, and the nozzle plug 31 is located between any one of the sleeves 33 and the spray pipe 32.

[0040] In the above embodiment, the strip-shaped nozzle 301 is provided on the spray pipe 32 and extends along the length direction of the spray pipe 32. Therefore, the length direction of the spray pipe 32 is also the length direction of the strip-shaped nozzle 301. When the spraying component 3 is stationary, the strip-shaped nozzle 301 can spray a thin line segment on the spraying surface. When the spraying component 3 moves along the S-shaped path, the strip-shaped nozzle 301 can spray an S-shaped line segment with a line segment width equal to the length of the strip-shaped nozzle 301 on the spraying surface.

[0041] In the above embodiments, any one sleeve 33 is fitted onto and rotatably connected to the nozzle 32. Each sleeve 33 has an opening on its periphery, which is aligned with and exposes the strip-shaped nozzle 301. A portion of the edge of this opening is helical and has a helical groove 331 that spirals around the sleeve 33. Simultaneously, one end of any nozzle sealing member 31 is slidably connected to the strip-shaped nozzle 301, and the other end is slidably connected to the helical groove 331. A sealing member driving device is connected to the sleeve 33 and can drive the sleeve 33 to rotate around the nozzle 32. For ease of description, the helical edge of the opening is referred to as the helical edge, and the helical groove 331 is located on and extends along the helical edge.

[0042] Based on the above-mentioned connection relationship between the sleeve 33 and its opening, the nozzle 32 and its strip nozzle 301, and the nozzle plugging member 31, when the plugging member driving device drives the sleeve 33 to rotate around the nozzle 32, on the one hand, limited by the relative motion state of the sleeve 33 and the nozzle 32, the nozzle plugging member 31 can slide along the strip nozzle 301. On the other hand, the nozzle plugging member 31 is always connected to the spiral edge of the opening. Therefore, the spiral edge where the nozzle plugging member 31 is located always intersects with the strip nozzle 301 on the nozzle 32. Thus, the part of the sleeve wall connected to the spiral edge can block the strip nozzle 301, thereby adjusting the length of the strip nozzle 301.

[0043] When the nozzle plug 31 and the sleeve wall that connects to the spiral edge are used to block the strip nozzle 301, the sleeve wall can effectively block the strip nozzle 301 and prevent the spray liquid from leaking from the blocked part. In addition, it can also reduce the restrictions on the shape and size of the nozzle plug 31. In other words, even if the size of the nozzle plug 31 is significantly smaller than the size of the sleeve 33 and the nozzle 32, the nozzle plug 31 can still work with the sleeve wall that connects to the spiral edge to achieve the expected effect.

[0044] For reference Figures 7 to 9 In the above embodiments, the sealing component driving device may include an electric push rod 34, a moving rod 35, and a moving plate 36; the outer surface of the sleeve 33 is provided with a spirally wound guide groove 332; the moving plate 36 may be disposed at the end of the electric push rod 34, one end of the moving rod 35 is inserted into the guide groove 332 on the surface of the sleeve 33 and slidably connected to the aforementioned guide groove 332, and the other end of the moving rod 35 is fixedly connected to the moving plate 36. When the electric push rod 34 extends or retracts, it drives the moving plate 36 and the moving rod 35 to move along a straight trajectory. At this time, the sleeve 33 rotates around the nozzle 32 under the cooperation of the moving rod 35 and the guide groove 332. As mentioned above, when the sleeve 33 rotates around the nozzle 32 in a specific direction, the nozzle sealing member 31 and the spiral edge of the sleeve 33 jointly block the strip nozzle 301, which can gradually reduce the length of the strip nozzle 301. When the sleeve 33 rotates around the nozzle 32 in the opposite direction, the nozzle sealing member 31 and the spiral edge of the sleeve 33 gradually expose the strip nozzle 301, which can gradually increase the length of the strip nozzle 301. Taking the spraying of arrow-shaped markings on the road surface as an example, the operator can move the moving carrier 1 while controlling the electric push rod 34 to adjust the length of the strip nozzle 301. The spraying operation of the arrow-shaped markings can be completed in one forward movement, avoiding the operator having to repeatedly move forward and backward in the same area to spray arrow-shaped markings.

[0045] For reference Figure 7 and Figure 9 In the above embodiments, any nozzle sealing component 31 may include a sliding plate 311, a first insertion part 312, and a second insertion part 313; wherein, the first insertion part 312 and the second insertion part 313 are respectively disposed on adjacent sides of the sliding plate 311, the first insertion part 312 is sealed and slidably connected to the strip nozzle 301, and the second insertion part 313 is sealed and slidably connected to the spiral groove 331; in addition, the radial dimension of the sliding plate 311 along the nozzle 32 is larger than the width of the strip nozzle 301, which can play a certain degree of shielding role for the strip nozzle 301 at its location, and more effectively seal the intersection of the sleeve 33 and the strip nozzle 301.

[0046] For reference Figure 3 , Figure 4 and Figure 6In some embodiments, the construction spraying equipment provided in this application further includes a cleaning component 4; the cleaning component 4 is disposed on the mobile carrier 1, and the spraying component 3 and the cleaning component 4 are distributed at intervals along the traveling direction of the mobile carrier 1. When using the construction spraying equipment provided in this embodiment, the cleaning component 4 is located in front of the spraying component 3, and can clean the spraying surface before the spraying component 3 sprays. For example, before the spraying component 3 sprays road markings onto the road surface, the cleaning component 4 can clean the road surface to prevent dirt on the road surface from affecting the spraying effect of the spraying component 3. In other words, it can enhance the adhesion between the spray liquid and the spraying surface and improve the service life of the road markings.

[0047] In the above embodiment, the cleaning component 4 may include a brush roller 41 and a debris removal device 42 adjacent to the brush roller 41. The brush roller 41 can rotate on a fixed axis to scrape off dirt adhering to the road surface. The debris removal device 42 is distributed adjacent to the brush roller 41 to collect or disperse debris generated when the brush roller 41 scrapes off dirt. In this embodiment, the cleaning component 4 first uses the brush roller 41 to clean the road surface, which can remove most of the dirt on the road surface. Then, it uses the debris removal device 42 to clean the road surface, removing the remaining debris and other dirt on the road surface, thereby improving the cleanliness of the road surface.

[0048] The debris removal device 42 can use air pressure to collect or disperse debris generated when the brush roller 41 scrapes away dirt. For example, the debris removal device 42 includes an air extractor 421, which can create a negative pressure environment near the brush roller 41 to suck up debris near the brush roller 41; the debris removal device 42 may also include a blower, which can blow air towards the brush roller 41 to disperse debris near the brush roller 41.

[0049] like Figure 6 and Figure 7 As shown, in some embodiments provided in this application, the debris cleaning device 42 uses an air extractor 421 as its main component, employing negative pressure to suck up debris generated when the brush roller 41 scrapes away dirt. In addition to the air extractor 421, the aforementioned debris cleaning device 42 also includes an air guide shell 422, which is interconnected with the air extractor 421, with the opening of the air guide shell 422 aligned with the brush roller 41. When the air extractor 421 is running, it generates a negative pressure environment on the brush roller 41 through the air guide shell 422, drawing the brush roller 41 into the air guide shell 422. Typically, a debris collection groove is provided between the air extractor 421 and the air guide shell 422 to collect and contain debris sucked in from the air guide shell 422, preventing the debris from entering the air extractor 421.

[0050] Based on the above embodiment, a protective shell 5 may be provided on the outer periphery of the brush roller 41. The opening of the protective shell 5 faces downward, and part of the opening of the protective shell 5 is adjacent to the opening of the air guide shell 422. In addition, the air guide shell 422 is provided with an inclined guide plate 4221 at its opening. The inclined guide plate 4221 gives the opening of the air guide shell 422 a "shovel" characteristic, which is beneficial for guiding the debris near the brush roller 41 into the air guide shell 422. The cross-section of the aforementioned inclined guide plate 4221 can be set as triangular, so the aforementioned inclined guide plate 4221 can be regarded as a triangular guide plate.

[0051] For reference Figure 3 and Figure 5 In some embodiments, the spraying liquid storage device 2 may include a storage tank 21 and a stirring device 22 disposed within the storage tank 21; a pulley mechanism 20 is provided between the aforementioned stirring device 22 and the brush roller 41, and this pulley mechanism 20 connects the drive of the brush roller 41 and the stirring device 22, in other words, the brush roller 41 and the stirring device 22 share the same power mechanism. The aforementioned storage tank 21 may specifically be configured as a paint tank, and the stirring device 22 is disposed within the paint tank to stir the spraying liquid in the paint tank and prevent the spraying liquid from settling and clumping. The paint tank is connected to the spraying assembly 3. Typically, a paint pump is provided between the paint tank and the spraying assembly 3. The paint pump pumps the spraying liquid in the paint tank out of the spraying assembly 3, so that the spraying liquid is sprayed onto the spraying surface. As the moving carrier 1 and the spraying assembly 3 move, the spraying assembly 3 can gradually complete the spraying construction of specific patterns such as road markings.

[0052] Typically, the mixing device 22 includes a mixing rod and a motor for driving the mixing rod to rotate. Obviously, the motor is the driver of the mixing device 22 mentioned above. The bottom of the aforementioned mixing rod can be connected to the pulley mechanism 20 through components such as a bevel gear set 30 and a transmission rod 40. The pulley mechanism 20 is then connected to the rotating shaft of the brush roller 41, thereby enabling the brush roller 41 and the mixing device 22 to share the same motor.

[0053] For reference Figures 3 to 6 In the above embodiments, both the spraying component 3 and the cleaning component 4 are mounted on the mounting base 6. The mounting base 6 is connected to the moving carrier 1 via a lifting device 7 and a sliding base 8. The sliding base 8 is slidably connected to the moving carrier 1, and the mounting base 6 is slidably connected to the sliding base 8. The lifting device 7 is connected to the sliding base 8. An arc groove 9 and a first sliding connector that slides along the arc groove 9 are provided between the aforementioned sliding base 8 and the aforementioned moving carrier 1. The arc groove 9 is distributed in the vertical plane. Therefore, the sliding base 8 and the moving carrier 1 can slide relative to each other in the vertical plane along the arc groove 9. A straight groove 10 and a second sliding connector that slides along the straight groove 10 are provided between the aforementioned mounting base 6 and the aforementioned sliding base 8. The straight groove 10 is distributed in the horizontal plane. Therefore, the mounting base 6 and the sliding base 8 can slide relative to each other in the horizontal plane along the straight groove 10.

[0054] When the spraying assembly 3 sprays paint onto surfaces with height differences, such as stepped surfaces, the lifting device 7 can drive the sliding seat 8 to rise or fall, thereby adjusting the height of the spraying assembly 3 to adapt to changes in the height of the spraying surface. During the aforementioned operation, due to the connection between the sliding seat 8 and the moving carrier 1, the sliding seat 8 rises or falls along the curved trajectory defined by the arc groove 9. At the same time, due to the connection between the mounting base 6 and the sliding seat 8, the spraying assembly 3 slides left and right along the straight trajectory defined by the straight groove 10, so that the brush roller 41 and the stirring rod (or transmission rod 40) maintain a constant axial distance.

[0055] It can be seen that the above-mentioned connection relationship of the components such as mounting base 6, lifting device 7, sliding base 8 and moving carrier 1 can not only meet the height adjustment requirements of brush roller 41, but also maintain a specific axial distance between brush roller 41 and the driver of stirring device 22, ensuring that brush roller 41 and stirring device 22 operate under the drive of the same power mechanism.

[0056] Furthermore, in some embodiments, the mobile carrier 1 may include a base and a handle disposed on the base; the base may be equipped with a controller for programmable sealing component drive device, and the handle may be equipped with a control key for key-controlled sealing component drive device. In the embodiments provided herein, the aforementioned controller and the aforementioned control key may be selected from one or both; in other words, in the spray liquid storage device 2, the base is equipped with a controller for programmable sealing component drive device and / or the handle is equipped with a control key for key-controlled sealing component drive device.

[0057] In summary, the spray liquid storage device 2 provided in this application can partially block the strip-shaped nozzle 301 using the sleeve 33 and the nozzle sealing component 31, thereby adjusting the actual spraying size of the strip-shaped nozzle 301, which is beneficial for quickly completing the spraying of special patterns such as arrows and improving spraying efficiency; the spray liquid storage device 2 provided in this application can clean the spraying surface, such as the road surface, using the brush roller 41 and the debris cleaning device 42, to avoid the sand and gravel on the road surface affecting the spraying effect of the spraying component 3; the spray liquid storage device 2 provided in this application can realize that the brush roller 41 and the stirring mechanism share the same power mechanism based on the lifting function of the brush roller 41. The former is beneficial for the spraying component 3 to carry out spraying operations on road surfaces with height differences, such as steps, while the latter is beneficial for reducing costs and equipment weight. As can be seen, the spray liquid storage device 2 provided in this application can flexibly adjust the spray width during spraying operations, improve the spraying effect of special patterns, automatically clean the road surface, reduce the impact of dust and other contaminants on the spraying quality, and flexibly adjust the height of the spraying component 3 to solve the problem of height difference affecting spraying, thereby improving the practicality of the equipment.
