Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a spraying device for building decoration and renovation projects. Background Technology

[0002] Building decoration and renovation projects encompass ten major categories, including building floors, plastering, exterior wall waterproofing, doors and windows, lightweight partition walls, decorative panels, facing bricks, curtain walls, and painting. The purpose of these projects is to protect various building components from natural elements like wind, rain, and moisture, improve thermal insulation, sound insulation, and moisture resistance, enhance building durability, and extend the building's lifespan. Simultaneously, they aim to create a better working, living, and production environment for people. During construction, spraying is required on building walls. Compared to manual labor, automated spraying equipment offers advantages such as high efficiency and shorter working hours.

[0003] Therefore, in the existing building decoration and renovation project spraying device, with the publication number CN221856098U, when in use, the fourth motor is turned on through the operation control panel. Under the support of the C-shaped frame, the fourth motor drives the first gear to rotate. Under the meshing action of the first gear and the second gear, the first gear drives the second gear to rotate, the second gear drives the support shaft to rotate, the support shaft drives the connecting arm to rotate, and the connecting arm drives the spray head to rotate.

[0004] However, during the rotating spraying process, it is difficult to keep the distance between the nozzle and the spray surface consistent. The distance between the nozzle and the spray surface will vary, which will result in a large difference in the adhesion effect of the paint at different positions on the spray surface. For example, when the distance is close, the paint is concentrated and the coating is thick, which may cause sagging; when the distance is far, the paint is dispersed and the coating is thin, or even missed spraying occurs, affecting the uniformity of the overall spraying quality. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a spraying device for building decoration and renovation projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spraying device for building decoration engineering, comprising a spraying box, a plurality of racks and a chassis are provided on one side of the spraying box, the plurality of racks are spliced ​​end to end and fixed by bolts, a movable wheel is provided at the bottom edge of the chassis, and a gear that meshes with the racks is rotatably installed in the middle, a liftable support plate is provided above the chassis, a support frame is fixedly connected to the top of the support plate, a threaded rod is rotatably connected to the inner side of the support frame, a lifting plate that is slidably installed with the support frame is threadedly connected to the threaded rod, a limit plate is fixedly connected to the top of the lifting plate by bolts, a spray head is provided between the lifting plate and the limit plate, and a pipe is connected between the spray head and the spraying box.

[0007] Preferably, the nozzles are arranged in a linear array, and the limiting plate has limiting grooves corresponding to the number and position of the multiple nozzles, with the nozzles located in the limiting grooves.

[0008] Preferably, two horizontally placed hydraulic rods with their telescopic ends facing each other are fixedly connected to both ends of the chassis. The telescopic ends of the two hydraulic rods are fixedly connected to push plates that are slidably installed with the chassis. Connecting rods are hinged to the opposite sides of the two push plates, and the other end of the connecting rods is hinged to a support plate.

[0009] Preferably, a motor is fixedly connected to both the chassis and the support plate. The motor spindle on the chassis is fixedly connected to a gear, and the motor spindle on the support plate is fixedly connected to a threaded rod.

[0010] Preferably, a spray pipe is fixedly connected to one side of the lifting plate, and a pressure pump is installed on the spray pipe. The input end of the pressure pump is connected to the spray pipe, and the output end is connected to the feed end of the nozzle. The spray pipe and the spray box are connected by a flexible hose.

[0011] Preferably, a manual hose reel is rotatably connected to the spray box, and the hose between the spray pipe and the spray box is wound around the manual hose reel. A connecting plate is fixedly connected to one side of the spray box, and the connecting plate is used to splice and fix with the rack.

[0012] Preferably, the spray box is equipped with a feed pump, the input end of which extends into the inside of the spray box, and the output end is connected to the hose between the spray pipe and the spray box.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a rack, multiple racks are spliced ​​together to form a longer rack. When the device is in use, it is placed along the spraying surface. By setting a chassis, the motor on the chassis controls the gear to rotate. The gear rolls along the rack, causing the chassis to slide along the rack, thereby causing the nozzle to move laterally relative to the spraying surface. By setting a lifting plate, the motor on the support plate drives the threaded rod to rotate, thereby causing the lifting plate to slide within the support frame, causing the nozzle to move longitudinally relative to the spraying surface. This ensures that the nozzle always maintains a fixed distance from the spraying surface during spraying, thus guaranteeing the uniform spraying effect of the device.

[0015] 2. In this utility model, by setting a hydraulic rod, when the extension end of the hydraulic rod is extended, it drives the push plate to slide. When the two push plates slide relative to each other or in opposite directions, they drive the connecting rod to move, thereby raising or lowering the support plate. The lifting and lowering of the support plate drives the overall lifting and lowering of the support frame, making the device easy to pass through the lintel, facilitating entry from the outside to the inside. It can also further adjust the height of the spray nozzle, increase the spraying range of the spray nozzle, and improve work efficiency. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4As shown, a spraying device for building decoration engineering includes a spray box 1. Multiple racks 4 and a base 7 are arranged on one side of the spray box 1. The racks 4 are spliced ​​end-to-end and fixed with bolts. A movable wheel 5 is provided at the bottom edge of the base 7, and a gear 13 rotatably mounted in the middle, meshing with the racks 4. A liftable support plate 6 is provided above the base 7. A support frame 10 is fixedly connected to the top of the support plate 6. A threaded rod 11 is rotatably connected to the inner side of the support frame 10. A lifting plate 19, which is slidably mounted on the threaded rod 11 and is connected to the threaded rod 11, is slidably mounted with the support frame 10. A limit plate 17 is fixedly connected to the top by bolts. A nozzle 16 is provided between the lifting plate 19 and the limit plate 17. The nozzle 16 is connected to the spray box 1 by a pipe. Multiple nozzles 16 are provided and distributed in a linear array. The limit plate 17 is provided with a limit groove 18 corresponding to the number and position of the multiple nozzles 16. The nozzles 16 are located in the limit groove 18. Motors 12 are fixedly connected to both the chassis 7 and the support plate 6. The main shaft of the motor 12 on the chassis 7 is fixedly connected to the gear 13. The main shaft of the motor 12 on the support plate 6 is fixedly connected to the threaded rod 11.

[0024] In this technical solution, a rack 4 is set, and multiple racks 4 are spliced ​​together to form a longer rack 4. When the device is in use, it is placed along the spraying surface. A base 7 is set, and when the gear 13 rolls on the rack 4, it drives the base 7 to slide on the ground and move forward along the rack 4. A support plate 6 is set, and the lifting and lowering of the support plate 6 drives the overall lifting and lowering of the support frame 10, making the device easy to pass through door lintels and convenient to enter from the outside to the inside. It can also further adjust the height of the spray head 16 to increase the spraying range of the spray head 16. A lifting plate 19 is set, and the electric motor on the support plate 6... The machine 12 drives the threaded rod 11 to rotate, which in turn drives the lifting plate 19 to slide within the support frame 10, causing the nozzle 16 to rise and fall. By setting a limiting plate 17, multiple nozzles 16 are placed between the limiting plate 17 and the lifting plate 19, and the nozzles 16 are clamped by tightening bolts, thus fixing the nozzles 16. When it is necessary to fine-tune the distance between the nozzle 16 and the spraying surface, the bolts are loosened to reduce the pressure between the limiting plate 17 and the lifting plate 19, and the nozzle 16 is moved to change the position of the nozzle 16 in the limiting groove 18, thereby adjusting the distance between the nozzle 16 and the spraying surface.

[0025] like Figure 2 As shown, two horizontally placed hydraulic rods 9 with their telescopic ends facing each other are fixedly connected to both ends of the chassis 7. The telescopic ends of the two hydraulic rods 9 are fixedly connected to push plates 15 that are slidably installed with the chassis 7. Connecting rods 8 are hinged to the opposite sides of the two push plates 15. The other end of the connecting rods 8 is hinged to the support plate 6.

[0026] In this technical solution, a hydraulic rod 9 is provided. When the extension end of the hydraulic rod 9 is extended, it drives the push plate 15 to slide. When the two push plates 15 slide relative to each other, the end of the connecting rod 8 connected to the push plate 15 moves closer to each other. Since the total length of the connecting rod 8 remains unchanged and the other two ends of the two connecting rods 8 are fixed, the connecting rod 8 will swing upward, thereby lifting the support plate 6. In addition, in order to ensure that the support plate 6 only moves in the lifting direction, a telescopic rod is fixedly connected between the support plate 6 and the chassis 7 to limit the lateral displacement of the support plate 6 relative to the chassis 7.

[0027] like Figure 3 As shown, a spray pipe 14 is fixedly connected to one side of the lifting plate 19. A pressure pump 21 is installed on the spray pipe 14. The input end of the pressure pump 21 is connected to the spray pipe 14, and the output end is connected to the feed end of the nozzle 16. The spray pipe 14 and the spray box 1 are connected by a hose.

[0028] In this technical solution, a spray pipe 14 is provided to hold the paint and a pressure pump 21 is installed. The paint delivered to the spray pipe 14 is rapidly sprayed out of the nozzle 16 by the pressure pump 21.

[0029] like Figure 1 As shown, a manual hose reel 3 is rotatably connected to the spray box 1. The hose between the spray pipe 14 and the spray box 1 is wound around the manual hose reel 3. A connecting plate 20 is fixedly connected to one side of the spray box 1. The connecting plate 20 is used to splice and fix with the rack 4.

[0030] In this technical solution, by setting a manual hose reel 3, when installing the device, the length of multiple spliced ​​racks 4 is determined according to the length of the spraying surface, and the length of the hose to be used is also determined. The construction personnel manually control the manual hose reel 3 to release the hose of the length corresponding to the length of the spraying surface. By setting a connecting plate 20, the multiple spliced ​​racks 4 are fixed to the spray box 1 to prevent the racks 4 from slipping during the operation of the device.

[0031] like Figure 1 As shown, a material pump 2 is installed on the spray box 1. The input end of the material pump 2 extends into the interior of the spray box 1, and the output end is connected to the hose between the spray pipe 14 and the spray box 1.

[0032] In this technical solution, a material pump 2 is provided to transport the spray material in the spray box 1 to the spray pipe 14.

[0033] Working principle: First, move the spray box 1 to one side of the spraying surface. Then, splice and fix multiple racks 4 end to end and place them parallel to the spraying surface. Next, splice and fix one rack 4 at the end to the connecting plate 20. Move the chassis 7 above the rack 4 and parallel to the spraying surface via the moving wheels 5. Then, mesh the gear 13 with the rack 4 to release a certain length of hose. When spraying begins, the motor 12 on the support plate 6 drives the threaded rod 11 to rotate, causing the lifting plate 19 to slide within the support frame 10 and rise and fall, thereby driving the nozzle 16 to rise and fall. At this time, the material pump 2 and the pressure pump 21 work. The spray material in the spray box 1 is sprayed out from the nozzle 16, so that the nozzle 16 sprays the spray surface longitudinally. When the lifting plate 19 moves from the top of the spray surface to the bottom of the spray surface, the motor 12 on the chassis 7 controls the gear 13 to rotate. The gear 13 rolls along the rack 4, which drives the chassis 7 to slide along the rack 4, and then drives the support frame 10, the lifting plate 19 and the limiting plate 17 to slide along the rack 4, thereby driving the nozzle 16 to move laterally along the spray surface. After the lateral movement is completed, the motor 12 on the support plate 6 works again to spray the spray surface longitudinally along the edge of the previously coated surface.

[0034] The wiring diagrams of the feed pump 2, hydraulic rod 9, motor 12 and pressurizing pump 21 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the feed pump 2, hydraulic rod 9, motor 12 and pressurizing pump 21 will not be explained in detail.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
