Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a painting device for house construction. Background Art

[0002] Building construction refers to projects with roofs, beams, columns, walls, foundations and internal spaces that can meet people's needs for production, residence, study, public activities, etc. The exterior walls of buildings will be eroded by wind, rain, snow, etc. during long-term use, so the buildings must be painted to protect them.

[0003] For example, a Chinese patent (publication number: CN214885218U) discloses a wall painting device for house construction, comprising a paint box and a third telescopic rod, the four ends of the bottom of the paint box are fixedly mounted with universal wheels, a liquid pump is fixedly mounted at the bottom of the inner side of the paint box, one end of the liquid pump is fixedly mounted with a liquid inlet pipe, the other end of the liquid pump is fixedly mounted with a liquid outlet pipe, one end of the liquid outlet pipe penetrates the paint box and extends to one side of the paint box, one end of the liquid outlet pipe is fixedly connected with a telescopic pipe, a hollow plate is fixedly mounted on the top of the third telescopic rod, a nozzle is fixedly mounted above the side wall of one side of the hollow plate, a mounting frame is fixedly mounted below the side wall of one side of the hollow plate, and a roller brush is movably mounted on one end of the mounting frame. The utility model provides a series of structures to enable the device to reduce the labor required for workers to carry paint, and does not require workers to dip in paint continuously during painting;

[0004] However, when the device is difficult to adapt to building surfaces of different shapes (such as corners, edges of doors and windows), and when the device is painting the wall, when painting to the edge of the wall, the width of the remaining unsprayed paint part of the wall is smaller than the width of the roller brush, if only the remaining unsprayed paint part of the wall is sprayed with paint, the remaining part of the roller brush will exceed the wall, and the nozzle corresponding to the roller brush that exceeds the wall will spray the paint in the remaining space, resulting in a waste of paint. If the paint roller is completely in contact with the wall, the previously painted part will be re-sprayed with paint, resulting in uneven paint spraying thickness, which reduces the painting quality. Therefore, a painting device for house construction is needed to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a painting device for building construction to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: A painting brush device for house construction, comprising a support assembly, an adjustment assembly, a control assembly, two limit racks, a material storage assembly, a brushing assembly and two reset assemblies, wherein the support assembly is a fixed shell;

[0007] The adjusting assembly comprises a threaded rod, the threaded rod is rotatably connected in a fixed shell, one end of the threaded rod is connected to a motor, the motor is connected to the fixed shell, the threaded rod is externally threaded with a threaded block, the top of the threaded block is connected to an electric push rod, and the movable end of the electric push rod is connected to the movable block;

[0008] The control assembly includes a controller, a plurality of ultrasonic sensors and a plurality of electromagnetic nozzles, and the controller is connected to the fixed shell;

[0009] The fixed shell is connected to two limit frames;

[0010] The material storage assembly includes a plastic hose, both ends of which are connected to a hard pipe, the top and bottom of the plastic hose and the hard pipe are provided with limit grooves, the limit frame and the movable block are slidably connected in the two limit grooves, and one end of one of the hard pipes is connected to a conduit through a water pump;

[0011] The brushing assembly comprises a first scraper and a second scraper, wherein the first scraper and the second scraper are both connected to one side of the plastic hose.

[0012] As a preferred solution, the bottom of the fixed shell is connected to a connecting frame, and the bottom of the connecting frame is connected to a connecting head.

[0013] As a preferred solution, a limiting block is connected inside the fixed shell, and the threaded block is slidably connected outside the limiting block.

[0014] As a preferred solution, the first scraper and the second scraper are made of elastic material.

[0015] As a preferred solution, the ultrasonic sensor and the electromagnetic nozzle are arranged between the first scraper and the second scraper, and the first scraper and the second scraper are both arranged in an inclined shape.

[0016] As a preferred solution, the reset assembly includes a connecting block, which is connected to the hard tube, and the adjacent sides of the two connecting blocks are connected to the guide rods, and the two guide rods are slidably connected in the limit frame. The guide rod is outer-mounted with a spring, and the two ends of the spring are respectively connected to the limit frame and the connecting block.

[0017] As a preferred solution, the conduit is connected to one of the hard pipes through a water pump, the hard pipe is connected to a plastic hose, and the plastic hose is connected to a plurality of electromagnetic nozzles.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] According to the present invention, when the plastic hose is in a straight tube state, the motor is controlled to work, and the moving limit block drives the movable block to move through the electric push rod. When the movable block moves to a suitable position, the electric push rod is controlled to shrink, and the shrinking electric push rod drives the plastic hose to deform through the movable block. The deformed plastic hose can bend according to the angle of the wall corner, and the bent plastic hose drives the first scraper and the second scraper to bend at the same time, and the lengths of both sides of the bending part of the plastic hose can be adjusted according to actual conditions, so that the device can be used for painting wall corners under different conditions;

[0020] In the present invention, when the first scraper and the second scraper of the device contact the wall, a plurality of ultrasonic sensors can monitor the wall in front of them. When there is no wall in front of the ultrasonic sensor, the controller controls the electromagnetic nozzle below the ultrasonic sensor to be closed, and at the same time the controller controls the remaining electromagnetic nozzles to be opened, so that the paint in the plastic hose can be evenly sprayed on the wall through the opened electromagnetic nozzles, so that the paint is not easily sprayed out of the part beyond the wall, which leads to the waste of paint, so that the paint can be sprayed on the wall surface with high quality;

[0021] In the present invention, since the electromagnetic nozzle is arranged between the first scraper and the second scraper, when the device moves from top to bottom, the second scraper moving downward can clean the wall, and then the paint is sprayed on the cleaned wall surface, so that the paint can adhere to the wall surface with high quality, and then the first scraper moving downward can scrape the paint on the wall evenly. It only needs to move the device to perform cleaning, spraying and scraping operations, and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
