DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the following preferred embodiments are cited with reference to the accompanying drawings for further detailed description of the present utility model. However, it should be noted that many details listed in the specification are only for enabling the reader to have a thorough understanding of one or more aspects of the utility model, and these aspects of the present utility model can be implemented even without these specific details.

[0016] Please refer to Figures 1 to 2 , the present utility model provides a plastering device for civil construction, and the technical solution is as follows:

[0017] It includes a bracket 1, the bracket 1 is a vertical stand, a threaded rod 2 is provided in the middle of the bracket 1, and two guide rods 3 are symmetrically provided on the bracket 1. A driving unit is provided at the bottom of the bracket 1, and the output shaft of the driving unit is connected to the threaded rod 2. A moving member is provided on the bracket 1, and a threaded hole matching the threaded rod 2 is provided on the moving member. Two spray heads 4 are symmetrically provided on the moving member, and a connecting pipe 5 is provided on each spray head 4. A stirring unit is provided outside the bracket 1, and each connecting pipe 5 is connected to the stirring unit. A smoothing component is provided on the bracket 1, and the smoothing component is located below the spray head 4.

[0018] Before the construction workers carry out the spraying and plastering operation, first, the cement mortar is stirred evenly by the stirring unit to meet the standard for spraying and plastering. Then, the bracket 1 is erected in front of the wall to be sprayed and plastered, and the two connecting pipes 5 are connected to the stirring unit. Subsequently, the driving unit is started, and the driving unit drives the threaded rod 2 to rotate, thereby driving the moving member and the smoothing component to move upward. At the same time, an external suction pump is provided to slowly spray the mixed cement mortar from the two spray heads 4. There is a certain gap between the moving member and the smoothing component. During the upward movement, the smoothing component levels the sprayed cement mortar until it moves to the top of the bracket 1, and then a single spraying and leveling operation is completed. Through the cooperation of the moving member and the smoothing component, the steps of manual operation are reduced, the labor intensity of the workers is reduced, and the density of the wall plastering layer is improved, thereby improving the quality of the wall.

[0019] The smoothing component includes a mounting frame 6 and a squeegee 7. The mounting frame 6 is provided on the bracket 1, and a slot 8 is provided in the mounting frame 6. Two squeegees 7 are provided in the slot 8, and a part of each of the two squeegees 7 extends outside the mounting frame 6. The two squeegees 7 in the mounting frame 6 are divided into an upper plate 701 and a lower plate 702. A through groove 703 is provided at one end of the upper plate 701 close to the inner side wall of the mounting frame 6. Under the combined action of the driving unit and the threaded rod 2, the mounting frame 6 moves upward stably. During the process, the two squeegees 7 in the mounting frame 6 level the cement mortar sprayed by the spray head 4. The two squeegees 7 are arranged vertically. Also, a through groove 703 is provided at a section of the upper plate 701 close to the mounting frame 6. When the upper plate 701 levels the cement mortar, the excess cement mortar will flow into the lower plate 702 through the through groove 703, and the lower plate 702 levels this part of the cement mortar on the wall again, reducing the loss of the cement mortar, improving the utilization rate of the cement mortar, and the secondary leveling of the lower plate 702 further ensures the density of the wall plastering layer.

[0020] The moving part is a moving frame 9, and the cross-sectional shape of the moving frame 9 is a C shape. Two spray heads 4 are symmetrically arranged at the top of the moving frame 9, and the mounting frame 6 is arranged inside the moving frame 9; a retention groove 10 is formed at the top of the support 1, the width of the retention groove 10 is greater than the width of the moving frame 9, and a smooth rod portion 11 is provided on the threaded rod 2 located in the retention groove 10.

[0021] Under the combined action of the driving unit and the threaded rod 2, the moving frame 9 moves steadily upward. At the same time, under the action of the pumping unit, the two spray heads 4 spray the cement mortar that has been stirred in the stirring unit onto the wall surface, and the smoothing assembly at the lower end of the moving frame 9 smooths it; the two spray heads 4 are arranged at the top of the moving frame 9 to avoid the smoothing assembly at the lower end hitting the spray heads 4 during upward movement, resulting in damage to both sides and improving stability; and the mounting frame 6 is arranged inside the moving frame 9. When it rises to the top, the moving frame 9 will enter the retention groove 10, and the threaded rod 2 has a smooth rod portion 11 in the retention groove 10. Since there is no thread on the smooth rod portion 11, the moving frame 9 will stay in the retention groove 10, and the mounting frame 6 continues to rise until it abuts against the moving frame; the driving unit rotates reversely, driving the threaded rod 2 to rotate reversely. However, at this time, the moving frame is in the retention groove 10 and will not rotate along with it. Instead, the mounting frame 6 moves downward under the reverse action of the threaded rod 2. When it moves to contact the lower end of the moving frame, it abuts against the moving frame and drives the upper end of the moving frame to engage with the threaded rod 2, and then follows the downward movement under the action of the threaded rod 2 until it returns to its original position.

[0022] Both of the two scraping plates 7 are arranged obliquely. The upper plate 701 is inclined upward, the lower plate 702 is inclined downward, and the cross-sectional shape of the two scraping plates 7 is in a shape of an inverted V; both of the two scraping plates 7 are arranged obliquely, and the upper plate 701 is inclined upward. When smoothing upward, the excess cement mortar will flow along the inclined upper plate 701 to the through groove 703, and then flow from the through groove 703 to the lower plate 702. And the lower plate 702 is inclined downward, and the excess cement mortar will contact the wall surface again along the inclined lower plate 702, so as to perform secondary smoothing on the excess cement mortar, improve the utilization rate of the cement mortar, reduce the waste of the cement mortar falling to the outside, and at the same time reduce the formation of cement waste after the fallen cement mortar dries, preventing the occurrence of difficult handling due to caking.

[0023] Working process:

[0024] Before the construction personnel carry out the spraying and plastering operation, they first mix the cement mortar evenly through the stirring unit to reach the standard for spraying and plastering, and then set up the bracket 1 in front of the wall to be sprayed and plastered, connect the two connecting pipes 5 with the stirring unit, and then start the driving unit, which drives the threaded rod 2 to rotate, and then drives the movable frame and the mounting frame 6 to move upward. At the same time, a pump is provided on the outside to slowly spray the mixed cement mortar from the two nozzles 4. The mounting frame 6 moves upward stably under the cooperation of the driving unit and the threaded rod 2. During the process, the two scrapers 7 in the mounting frame 6 evenly spread the cement mortar sprayed from the nozzle 4 until the movable frame 9 moves into the retention groove 10; the driving unit rotates in the opposite direction, driving the threaded rod 2 to rotate in the opposite direction, and the mounting frame 6 moves downward under the reverse action of the threaded rod 2. When it moves to contact the lower end of the movable frame, it presses against the movable frame to drive the upper end of the movable frame to pinch the threaded rod 2, and then moves downward under the action of the threaded rod 2 until it is reset.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
