Description

Technical Field

[0001] The utility model relates to the technical field of building spraying, in particular to a paint spraying device for building construction. Background Art

[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid based on resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, prepared with organic solvents or water. During existing construction, it is necessary to spray paint on the wall to achieve the purposes of thermal insulation, corrosion resistance, and aesthetics. Therefore, a paint spraying device for construction is needed.

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN213115392U) discloses a device for spraying exterior wall paint for construction, in which a stirring shaft is driven to rotate by a second drive motor, so that the stirring shaft drives a sun gear, a stirring blade and a stirring rod to rotate, and the stirring blade and the stirring rod stir the paint inside a mixing barrel, and the sun gear drives the planetary gear to rotate, so that the planetary gear drives the first rotating shaft to rotate, and the first rotating shaft drives an auger and a scraper to rotate, and the auger transports the paint at the bottom of the mixing barrel to the stirring blade, and the scraper removes the paint on the inner wall of the mixing barrel, thereby achieving uniform stirring of the paint inside the mixing barrel and enhancing the stirring effect of the paint.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed exterior wall paint spraying device for construction has the following problems: although the exterior wall paint spraying device for construction can stir the internal paint to prevent the paint from sinking to the bottom, it is unable to recycle the paint splashed from the wall, which not only increases the cost of use but also pollutes the environment. In view of this, a paint spraying device for construction is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a coating spraying device for building construction.

[0007] As a further description of the above technical solution: a pin shaft is arranged in the storage tank, and a sealing piece is rotatably sleeved on the pin shaft, and the sealing piece is abutted against the feed port. The filtered paint can push the sealing piece along the feed port to rotate around the pin shaft and enter the storage tank, thereby preventing the paint collected in the storage tank from being spilled to the outside due to the movement of the base.

[0008] As a further description of the above technical solution: the number of the pin shafts is two, and the two pin shafts are symmetrically installed in the storage tank, which can improve the stability of the rotation of the sealing member.

[0009] As a further description of the above technical solution: a stirring shaft is rotatably arranged in the storage tank, a plurality of stirring rods are fixedly mounted on the stirring shaft, the stirring rods and the fixed tubes do not contact each other, a motor is fixedly mounted on the top of the storage tank, a driving shaft of the motor is fixedly connected to one end of the stirring shaft, and when the motor is turned on, the stirring shaft can drive the stirring rods to rotate and stir the paint in the storage tank, thereby preventing the paint from sinking to the bottom and improving the quality of the paint.

[0010] As a further description of the above technical solution: the number of the stirring shafts is two, and the two stirring shafts are symmetrically installed in the storage tank, and gears are fixedly sleeved on the two stirring shafts. The two gears are meshingly connected, and the motor is fixedly connected to one of the stirring shafts. When the two stirring shafts rotate, due to the meshing connection of the two gears, the two stirring shafts will rotate in opposite directions, which can avoid the formation of columnar bad areas during stirring and improve the uniform mixing effect of the paint.

[0011] As a further description of the above technical solution: a plurality of stirring rods are arranged on the stirring shaft at equal intervals, and the stirring rods on two stirring shafts do not contact each other.

[0013] As a further description of the above technical solution: casters are provided at the four corners of the bottom of the base, a handle is fixedly installed on one side of the base, and a controller is provided on one side of the handle. The controller is electrically connected to the negative pressure pump, motor and electric push rod, which facilitates the movement of the base and also facilitates personnel to control the switch and operating status of the negative pressure pump, motor and electric push rod.

[0014] The utility model has the following beneficial effects:

[0015] The paint spraying device for construction designed by the utility model can, by turning on the negative pressure pump, enable the fixed pipe to transport the paint in the storage tank to the nozzle and spray it out. When spraying the paint on the wall, part of the paint will rebound and fall due to the collision with the wall. At this time, the paint will fall into the receiving trough and be filtered by the filter. Then the filtered paint flows into the storage tank along the feed port, so the effect of recycling the paint can be achieved, which not only reduces the use cost but also avoids polluting the external environment.

[0016] The paint spraying device for construction designed by the utility model can turn on the motor, and since the two gears are meshed and connected, the two stirring shafts can drive the stirring rods to rotate in opposite directions, which can not only stir the paint in the storage tank to prevent precipitation, but also avoid the formation of columnar bad areas by stirring, and can improve the uniform mixing effect of the paint. By turning on the electric push rod, the driving end of the electric push rod can be extended and retracted, and the height of the storage tank and the spray head can be adjusted, so that it is suitable for spraying walls of different heights.

[0024] During specific implementation, the negative pressure pump 5 is turned on, so that the fixed pipe 4 can transport the paint in the storage tank 2 to the nozzle 3 and spray it out. When the paint is sprayed on the wall, part of the paint will rebound and fall due to the collision with the wall.
