In some embodiments, the spatula 400 is at least partially a resilient plate, and the resilient plate contracts and deforms when the spatula 400 is pressed. The elastic plate of the partial troweling plate 400 is connected with the bracket 200, so that the troweling plate 400 is flush with the rolling surface 600 when the roller 100 contacts the wall surface 500, for example, the upper end part of the troweling plate 400 is made of elastic material and is connected with the bracket 200, the troweling plate 400 extends out of the rolling surface 600 in a non-working state, when the rolling surface 600 is overlapped with the wall surface 500, the wall surface 500 extrudes the troweling plate 400, the troweling plate 400 can be compressed backwards due to the elastic action, and the troweling plate 400 is tightly pressed on the wall surface 500 under the elastic action, so that a better troweling effect is achieved.

In some embodiments, as shown in fig. 1 to 3, the trowel 400 is integrally and movably disposed on the support 200, and the wall surface troweling apparatus 1000 further includes a torsion spring 330, the torsion spring 330 is connected between the trowel 400 and the support 200, and the torsion spring 330 acts to push the trowel 400 so that the lower end of the trowel 400 extends out of the rolling surface 600.

In some embodiments, as shown in fig. 1-3, the wall surface smoothing device 1000 further comprises: extrusion mechanism 300, extrusion mechanism 300 includes: the mounting seat 320 and the wiping plate 400 are arranged on the mounting seat 320, the mounting seat 320 is movable relative to the support 200, one end of the torsion spring 330 is connected with the mounting seat 320, and the other end of the torsion spring is connected with the support 200. That is, the torsion spring 330 enables the floating plate 400 on the mounting seat 320 to move when the roller 100 contacts the wall surface 500, when the rolling surface 600 is overlapped with the wall surface 500, the roller 100 starts the floating operation, at this time, the floating plate 400 is compressed backwards through the extrusion mechanism 300, that is, the wall surface 500 enables the torsion spring 330 to be compressed, the lower ends of the mounting seat 320 and the floating plate 400 are retracted, the extrusion mechanism 300 enables the floating plate 400 at the lower end to form a certain extrusion with the wall surface 500, and the secondary extrusion floating effect is achieved while the roller 100 is floating.

In some embodiments, as shown in fig. 2 and 3, the pressing mechanism 300 further comprises: a fixed seat 310 and an adjusting block 312 movably arranged on the fixed seat 310. The fixing seat 310 is disposed on the bracket 200, the mounting seat 320 is pivotally disposed on the fixing seat 310, and the torsion spring 330 is disposed between the fixing seat 310 and the mounting seat 320. That is, during the troweling operation of the troweling plate 400, the torsion spring 330 elastically rotates the mounting seat 320 on the fixing seat 310, so that the troweling plate 400 is retracted by rotating counterclockwise. One end of the adjusting block 312 abuts against the mounting seat 320, and the adjusting block 312 can adjust the position of the mounting seat 320 to adjust the protruding distance of the trowel 400 relative to the rolling surface 600. That is, by moving the adjusting block 312, the mounting seat 320 can be further pressed, so as to adjust the position of the mounting seat 320 on the fixing seat 310, and finally adjust the extending distance of the trowel 400 relative to the rolling surface 600, so as to adjust the extrusion amount of the trowel 400 on the wall 500 and control the extrusion effect.

It should be noted that the protruding distance of the trowel 400 relative to the rolling surface 600 can be adjusted according to the characteristics of the trowel material, for example, as shown in fig. 5, the trowel 400 may exceed the rolling surface 600 by a certain range of 0-8mm before the wall surface trowel device 1000 contacts the wall surface 500, the coarse-grained ready-mixed mortar can be adjusted by a range of 2-3mm, and the fine-grained anti-crack mortar and putty can be adjusted by a range of 0.5-1.5 mm. By adopting the wall surface trowelling device 1000, even if the particle sizes of different materials are different, thick particles which are mixed on the surface and influence the quality cannot be effectively taken away due to overlarge particles and insufficient extrusion amount, so that the wall surface 500 is prevented from being damaged by pulling in the secondary extrusion and light receiving process; the wall surface 500 is not scratched due to repeated elastic deformation of the trowelling plate in the secondary extrusion light-receiving process caused by excessively fine particles and excessively large extrusion amount. Of course, the above specific numerical ranges are only examples, and the range of the trowel 400 exceeding the rolling surface 600, the adjustable range of the coarse-grained ready-mixed mortar, the adjustable range of the fine-grained anti-crack mortar and the adjustable range of the putty may be other ranges, which are not specifically described herein.

The method of use of the wall screeding device 1000 of the present invention is described below:

1. the wall surface troweling device 1000 is fixedly mounted on a vertical moving shaft (i.e., a lifting mechanism).

2. After reaching the operation point, the roller is driven by an external moving shaft to vertically move upwards along the wall surface 500, and in the moving process, the roller 100 automatically rotates by the friction force of the wall surface 500 to finish the floating and preliminary compaction work of the target wall surface 500; the scraper 110 arranged at the rear end prevents the roller 100 from adhering flash to pollute the wall surface 500 or strain the wall surface 500; and since the upper end is the small diameter of the drum 100, it can be almost covered to the top of the wall.

3. In the process of vertical lifting movement, the trowelling plate 400 extruded from the lower end completes trowelling operation at the wall root, so that the trowelling coverage rate of the wall surface 500 can exceed 95%; meanwhile, the secondary compaction operation of the wall surface 500 which is already leveled by the roller 100 at the upper end is completed along with the rising process, so that the compaction degree of the wall surface 500 is greatly increased, and hollowing and cracking are prevented.

In addition, the elasticity of the three extrusion mechanisms 300 can be adjusted according to the working condition of the wall surface 500 and the characteristics of the material to be smeared, and meanwhile, the adjusting blocks 312 at the two ends can be adjusted to achieve the adjustment of the secondary compaction size.

After the equipment is in place and the posture adjustment is completed, the wall surface 500 is trowelled by the actuator under the driving of the external moving shaft. In the moving process, the roller 100 rotates by the friction force of the wall surface 500 to finish the floating and preliminary compaction work of the target wall surface 500; the scraper 110 arranged at the rear end prevents the roller 100 from adhering flash to pollute the wall surface 500 or scratching the wall surface.

Compare prior art, the direct floating disadvantage of traditional floating plate lies in:

taking mortar trowelling as an example, the traditional trowelling only adopts a trowelling plate which forms a certain included angle with the wall surface to be trowelled. Like this at the floating slab in-process of floating upwards, constantly piling up of floating slab top mortar leads to the floating slab to warp the bending gradually, causes the lower tip of floating slab and treats to float and can be separated by the mortar between the wall 500, like this with treat that to float wall direct contact be the mortar, but not the lower tip of floating slab, lead to the wall 500 to float the quality low.

The wall surface troweling apparatus 1000 of the present invention has the advantages of:

the roller 100 can rotate by means of friction force of the wall surface 500, mortar can be discharged in time, mortar in the floating process can be effectively prevented from being accumulated, rolling is formed by rotation between the roller 100 and the wall surface 500, binding force of the mortar and the wall surface 500 can be effectively increased, and hollowing is prevented. In addition, carry out preliminary floating to the wall through cylinder 100, the lower tip of floating slab carries out the fine floating again to the wall for the floating quality of wall is higher.
