[0002] Plastering is a traditional construction method of applying mortar on the walls, floors and ceilings of building structures. Plastering projects are divided into internal plastering and external plastering. Usually, plastering located in various parts of the interior is called internal plastering, such as floor, ceiling, dado, skirting, internal stairs, etc.; plastering located in various parts of the exterior is called external plastering, such as exterior walls, awnings, balconies, roofs, etc. In the existing plastering device, the plastering board is not easy to disassemble, which makes it inconvenient to clean the plastering board. Secondly, during the plastering process, mortar is easy to drip onto the ground. After the plastering is completed, the ground needs to be cleaned, which leads to poor practicality of the device. For this purpose, application number: 202220722712.4 discloses a plastering device for construction in the field of construction engineering technology, comprising a base, a support rod is fixedly connected to the top surface of the base, a fixing plate is fixedly connected to the top of the support rod, a threaded screw is rotatably connected between the base and the fixing plate, a driving motor is fixedly connected to the top surface of the fixing plate, one end of the output shaft of the driving motor is fixedly connected to the threaded screw, and the threaded screw is fixedly connected to the top surface of the fixing plate.

There is no need for personnel to remove the plastering plate 109 separately for cleaning, which improves cleaning efficiency and facilitates personnel operation. In addition, after the plastering work is completed, the telescopic hose 7, L-shaped connecting pipe 8, diversion box 108 and multiple spraying pipe heads can be cleaned, which can effectively reduce the situation where mud solidifies in the pipe body and causes blockage, thereby improving the stability of use.

[0030] Working principle: When in use, mortar is placed in the mortar box 107 in advance, and the entire device can be moved by four walking wheels. When performing plastering operations, after the entire device moves to the position to be plastered, the drive motor 103 is first started in reverse, and the output shaft of the drive motor 103 drives the screw 102 to rotate. Under the action of the threaded hole provided on the moving block 104, the screw 102 rotates and drives the moving block 104 to slide downward on the two L-shaped guide rods 101. When the moving block 104 drives the plastering plate 109 to move downward to the lowest position, the drive motor 103 is stopped, and then the mud pump 1 and the solenoid valve 4 on the left are turned on. The mud pump 1 passes through the three-way pipe 3 and the solenoid valve 4 on the left in turn. The mortar inside the mortar box 107 is extracted with the first L-shaped tube 5, and the extracted mortar is sprayed onto the wall through the telescopic hose 7, the L-shaped connecting tube 8, the diverter box 108 and the multiple spraying pipe heads in sequence. At the same time, the driving motor 103 is turned on in the forward direction, which is opposite to the movement process of the driving motor 103 when it is started in the reverse direction, so that the moving block 104 drives the plastering plate 109 to move upward to smooth the sprayed mortar, thereby achieving the plastering effect. When mortar falls during the plastering process, the fallen mortar falls directly into the receiving box 105 and enters the mortar box 107 through the guide pipe 106, thereby achieving the purpose of collecting the fallen mortar and reducing the situation of mortar falling on the ground;

[0031] The distance value for closing the first electric telescopic rod 10 is set in advance by the controller 15. After plastering for a period of time, the left side of the plastering plate 109 will be stained with more mortar. When it needs to be cleaned, the corresponding wireless remote control switch is first controlled by the external remote control to control the first electric telescopic rod 10 to open in the forward direction. The output shaft of the first electric telescopic rod 10 drives the scraper 12 to move left through the multi-stage electric telescopic rod 11. The scraper 12 drives the distance measuring sensor 13 to move left. The distance measuring sensor 13 measures the distance between it and the reflector 14 and transmits its measured value to the controller 15. When the distance value reaches the preset value, the right side of the scraper 12 and the left side of the plastering plate 109 are in the same vertical line. At this time, the controller 15 controls the first electric telescopic rod 10 to close, and then controls the multi-stage electric telescopic rod 11 to open in the forward direction through the external remote control. The multi-stage electric telescopic rod 1 The output shaft of 1 drives the scraper 12 to move downward and generate friction with the left side of the plastering plate 109. Under the friction force, the mortar attached to the left side of the plastering plate 109 can be effectively scraped off, and the scraped mortar can be sequentially passed through the receiving box 105 and the guide pipe 106 to enter the mortar box 107 again, and the mortar box 107 collects the attached mortar, thereby reducing the waste of mortar. After the scraping is completed, the multi-stage electric telescopic rod 11 is driven in the reverse direction, so that the scraper 12 is converted to move back upward and reset, and then the first electric telescopic rod 10 is started in the reverse direction, so that the scraper 12 is converted to move right and reset. After the movement and reset, the multi-stage electric telescopic rod 11 and the first electric telescopic rod 10 can be closed in sequence, thereby achieving the purpose of scraping and cleaning the mortar attached to the left side of the plastering plate 109. This cleaning method does not require personnel to remove the plastering plate 109 separately for cleaning, thereby improving cleaning efficiency and facilitating personnel operation.

[0032] After the plastering work is completed, when there is still mortar in the mortar box 107, the solenoid valve 4 on the left can be closed and the solenoid valve 4 on the top can be opened. At this time, the mud pump 1 is transformed into extracting water from the water tank 2 through the three-way pipe 3, the upper solenoid valve 4 and the L-shaped extraction pipe 6 in sequence. The extracted water is sprayed out through the telescopic hose 7, the L-shaped connecting pipe 8, the diverter box 108 and the multiple spraying pipe heads in sequence, so that the water flows inside them for flushing. By extracting and spraying water, the telescopic hose 7, the L-shaped connecting pipe 8, the diverter box 108 and the multiple spraying pipe heads can be effectively cleaned. By cleaning after plastering, the situation of mud solidifying in the pipe body and causing blockage can be effectively reduced, without affecting the operation of reuse, thereby improving the stability of use.

[0033] In addition, after the mortar inside the mortar box 107 is used up and the plastering work is completed, water can be directly added to the mortar box 107, and the water inside the mortar box 107 can be directly extracted by the mud pump 1 to clean the mortar box 107, the first L-shaped tube 5 and the solenoid valve 4 on the left.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
