[0027] The working principle and use process of this utility model:

[0028] During use, water required for spraying is pumped into the connecting pipe 351 by connecting a water pump. When the water enters the filter element 35 through the connecting pipe 351, it is filtered by the filter element 35 and then discharged into the storage barrel 32 through the filter barrel 34. Then, the valve of the valve pipe 43 is opened to allow the filtered water to be sprayed out through the spray head 42. At this time, the motor 12 is started to drive the threaded rod 13 to rotate, so that the threaded rod 13 drives the slide 14 to move, so that the slide plate 2 moves, thereby moving the spray head 42 to spray, thereby increasing the spraying area. By pressing the switch, the motor 12 rotates in the opposite direction, so that the spray head 42 sprays reciprocally, thereby improving the spraying effect.

[0029] When the spraying is completed, close the valve pipe 43 and turn off the motor 12. During use, the worker can stand on the sliding plate 2 for secondary stirring. After the concrete surface fully absorbs water, use the stirrer to stir the concrete for the second time until liquid appears on the concrete surface and reaches the required density and flatness. Then the worker can use the finishing tool to finish the concrete surface to ensure that the surface is flat and smooth. When maintenance is required, the above spraying process can be repeated again to spray the cement for maintenance.
