Description

Technical Field

[0001] The utility model belongs to the technical field of wall construction, in particular to an anti-air-drum wall plastering device. Background Art

[0002] Plastering mortar is a general term for a type of mortar that is applied to the building base surface for leveling or protection. Depending on the operation, plastering mortar is divided into on-site mixed mortar and premixed dry powder plastering mortar. Premixed dry powder plastering mortar is a type of commercial mortar, among which dry powder plastering mortar is made of cement, filler, aggregate and a variety of functional admixtures. Plastering mortars with different functions are used on different wall substrates. For example, there are plastering mortars suitable for lightweight walls such as aerated concrete blocks, fly ash blocks, expanded clay bricks, and directly applied on the surface of concrete shear walls. In order to prevent the plastering mortar from hollowing and cracking, it needs to be polished. The current polishing device usually produces a lot of smoke and dust during polishing, which affects the air quality.

[0003] For example, a Chinese utility model patent with announcement number CN219617331U discloses a device for smoothing plaster mortar to prevent hollowing and cracking. The device comprises a support frame with a hollow interior provided with a threaded rod. A first bevel gear is connected to one end of the threaded rod. The first bevel gear is meshed with a second bevel gear. The second bevel gear is connected to a first motor. The first motor drives the first bevel gear to rotate, thereby driving the second bevel gear to rotate, so that the threaded rod rotates. The threaded rod penetrates a moving block. The inner wall of the moving block in contact with the threaded rod is provided with a thread, which meshes with the thread on the surface of the threaded rod. When the threaded rod rotates, the moving block can move along the threaded rod.

[0004] However, after the wall is plastered, hollows are prone to occur due to uneven plastering, and the wall plastering needs to be smoothed. During the process of smoothing the wall, the device not only generates dust, but also large particles of dust fall as the vertical wall is plastered and smoothed. When these large particles of dust fall to the ground, they will contaminate the ground, requiring subsequent staff to clean the ground, which increases the staff's extra cleaning workload.

[0005] In summary, there is a need for a wall plastering device that can clean dust in time. Utility Model Content

[0034] The implementation principle of an anti-air-drum wall plastering device in an embodiment of the present application is: after pushing the device to the work site, start the electric push rod, drive the moving wheel to retract upward through the fixed plate, so that the support column is fixed on the ground, making the device more stable during operation.

[0035] After the device is fixed, the third motor is started according to the height of the wall, so that the third motor drives the bidirectional screw rod 7 to rotate, and the two movable seats 9 move relative to each other, so that the scissor rods 11 shrink inward, and then the height of the top plate 8 is adjusted, thereby increasing the overall height of the device, making it convenient for the device to perform plastering work on walls of different heights within a certain range, thereby increasing the applicability of the device.

[0036] After the height adjustment is completed, the second motor is started first to drive the second screw rod to rotate, so that the second movable block 6 moves horizontally. After the horizontal position is adjusted, the discharge pump and the first motor are started, and the first motor drives the first screw rod 3 to rotate, so that the first screw rod 3 drives the plastering part 19 to perform up and down plastering work. After the plastering is completed, the second motor is started again to drive the second screw rod to rotate, thereby adjusting the second movable block 6 for horizontal position adjustment until the plastering of a certain range of the wall is completed.

[0037] After the wall surface is completely dried, the direction of the device is reversed, and the smoothing motor 15 and the water outlet pump 16 are started again, so that when the smoothing motor 15 is working, the precipitation member 13 sprays water through the water outlet nozzle, and at the same time, the dust cover 12 is attached to the wall surface, so that the smoke and dust generated when the smoothing disc 17 smoothes the wall surface falls to the bottom of the dust cover 12 under the action of water, and at the same time, large particles of dust also fall into the dust cover 12, so that the smoke and dust impurities and large particles of dust also fall into the interior of the dust box 20 under the action of the dust suction pipe, and are filtered by the pull-out box 21. The smoke and dust impurities and large particles of dust are all collected by the pull-out box 21, and the water flows to the bottom of the dust box 20, and then the water flow is re-pumped into the interior of the water tank through the reflux pump 18, which not only realizes the repeated use of the water flow and improves the utilization rate of water resources, but also recycles large particles of dust and smoke and dust impurities to prevent them from falling, thereby reducing the subsequent cleaning work required.

[0038] In addition, the same or similar element symbols are used to refer to the same or similar parts or steps in the drawings and descriptions as much as possible. The drawings are presented in simplified form and are not drawn to exact scale. For convenience and clarity only, directional terms such as top, bottom, left, right, upward, above, above, below, below, behind, and in front may be used with respect to the drawings.
