Description

Technical Field

[0001] The utility model relates to the technical field of trowel machines, in particular to a wall trowel machine for construction. Background Art

[0002] At present, when plastering the wall, a plastering machine is usually used to plaster the wall, which reduces labor intensity and greatly improves work efficiency. The prior art announcement number is CN216766669U, which discloses a wall plastering machine for construction, including a mobile base, the upper surface of the mobile base is fixedly connected with a fixed column, the outer surface of the fixed column is slidably connected with a lifting sleeve, the outer surface of the lifting sleeve is fixedly connected with a plastering box, the side of the plastering box is hinged with a plastering plate, the side of the plastering plate is opened with a through hole, and the inner wall of the through hole is provided with a nozzle, the lower surface of the plastering box is provided with an adjusting mechanism, and the side of the plastering box is provided with a slurry pump. The wall screed machine for construction uses a servo motor to start the screw rod to drive the screed box to rise and fall, and uses the screed board to apply the slurry on the wall, so that the workers can perform the screed operation on the ground, reducing the safety hazards during the construction process. The screed board is driven to rotate by the screw rod to adjust the distance from the wall, and the thickness of the screed is adjusted. At the same time, the thickness of the screed is kept consistent, reducing the workload of subsequent leveling.

[0003] In the actual wall plastering process, after the plastering machine moves up and down, it is necessary to move the plastering machine left and right to plaster adjacent areas of the same wall. It is difficult to ensure that the plastering machine is parallel to the wall during the movement, and the plastering thickness needs to be repeatedly adjusted. This process mostly relies on manual experience to control its quality. Based on this, the existing plastering machine has the problem of being difficult to move left and right, resulting in large repeated positioning errors and the need for repeated adjustment of the plastering thickness, which needs further improvement.
