Description

Technical Field

[0001] The utility model belongs to the technical field of wall repair, and in particular relates to a paint spraying device for wall repair. Background Art

[0002] Buildings refer to man-made assets and fall under the category of fixed assets, including two major categories: houses and structures. Houses refer to engineering buildings for people to live, work, study, produce, operate, entertain, store items and conduct other social activities. Structures are different from buildings. Structures refer to engineering buildings other than houses. From an architectural point of view, the components that enclose buildings to form the boundary between indoor and outdoor are called exterior walls. Its functions include: bearing certain loads, blocking wind and rain, keeping warm and insulating, preventing noise, and fire safety. As the use time increases, the exterior walls of the building will show certain damage, and a wall repair paint spraying device will be needed.

[0003] At present, a Chinese patent with announcement number CN217342010U discloses a paint spraying device for repairing the exterior walls of buildings, including a support seat, a mixing box fixedly connected to the top of the support seat, a connecting shaft rotatably connected inside the mixing box, a rotating seat rotatably connected inside the mixing box and located on the outside of the connecting shaft, one end of the rotating seat is fixedly connected to a connecting rod, a stirring rod is equidistantly provided on one side of the connecting rod and the outside of the connecting shaft, the top of the support seat is fixedly connected to a support plate, and a lifting seat is slidably connected to the outside of the support plate.

[0004] However, when the above device is used, after spraying, the paint on the wall is not uniform enough, and the staff still needs to apply paint on the wall later, which increases the labor intensity of the staff. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a paint spraying device for wall repair. The advantage of the utility model is that it can reduce the labor intensity of the workers.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A paint spraying device for wall repair comprises a body, a coating mechanism is provided on one side of the top of the body, and a spraying mechanism is provided on one side of the top of the body;

[0008] The smearing mechanism includes an electric hydraulic rod fixedly connected to the top side of the vehicle body, the top of the piston rod of the electric hydraulic rod is fixedly connected to a connecting plate, one side of the connecting plate is provided with a connecting groove, one side inner wall of the connecting groove is fixedly connected to a connecting spring, one side of the connecting spring is fixedly connected to a connecting frame that forms a sliding fit with the inner wall of the connecting groove, and the same smearing roller is rotatably connected between the inner walls of the two ends of the connecting frame through bearings, which can reduce the labor intensity of the staff.

[0009] A drying port is provided on one side of the connecting plate, and a hot air blower is fixedly connected to one side of the connecting plate. The exhaust end of the hot air blower is communicated with the drying port. The setting of the hot air blower can make hot air blow out through the inner wall of the drying port, and can dry the evenly applied paint.

[0010] The inner wall of the drying port is inclined so that the hot air blown out of the drying port is directed downward and blown along the flow direction of the paint, thereby preventing the hot air from flowing upward and causing bulges on the surface of the paint.

[0011] The spraying mechanism includes a nozzle fixedly connected to one side of the connecting plate, the coating roller is located between the nozzle and the drying port, the top of the vehicle body is fixedly connected to a paint box, and the inner wall of one side of the paint box is fixedly connected to a pump connected to the paint box. The pump and the nozzle are fixedly connected through a feed pipe. The setting of the pump can spray the paint in the paint box through the nozzle when it is started, so that the wall can be sprayed.

[0012] A cover plate is provided at the top opening of the paint box, which forms a sliding fit with the inner wall of the paint box. The bottom of the cover plate is fixedly connected to a fixing rod, and the bottom of the fixing rod is fixedly connected to a mesh plate. The arrangement of the mesh plate allows it to move when the cover plate moves up and down, so that the upper and lower layers of paint can be mixed, thereby avoiding stratification of the paint.

[0013] Limiting grooves are provided on both sides of the top of the paint box. The inner walls of the limiting grooves are slidably connected to limiting blocks. The limiting blocks are fixedly connected to the cover plate. The setting of the limiting blocks allows them to slide in the inner walls of the limiting grooves, allowing the cover plate to move up and down.

[0014] The limit block has a T-shaped structure, and a reset spring is fixedly connected to the bottom of the limit block. The T-shaped structure design can avoid separation between the limit groove and the inner wall of the limit block, and the reset spring can facilitate the reset of the cover.

[0015] The beneficial effects of the utility model are:

[0016] 1. The paint spraying device for wall repair can make the coating roller roll along the wall through the electric hydraulic rod. The thickness of the applied paint can be adjusted by the elastic force of the connecting spring. When the coating roller rolls, starting the hot air blower can make the drying port blow out hot air with a suitable wind speed to dry the paint, thereby reducing the labor intensity of the staff.

[0017] 2. The paint spraying device for wall repair can mix the paint by holding the handle on the cover plate and moving it up and down to make the limit block slide in the limit groove. BRIEF DESCRIPTION OF THE DRAWINGS
