A second extension rod 22 that cooperates with the width adjustment mechanism is also provided on the protective shell 1, and one end of the second extension rod 22 is embedded in the front connecting plate 14.

[0041] In actual use, by setting up a smoothing mechanism, it is convenient to use the drive motor 29 to drive the scraper 27 and the smoothing blade 28 to rotate, thereby eliminating small unevenness and tiny potholes on the concrete floor. By setting up the smoothing blade 28, it is convenient to hang out small solids to make the floor smoother, thereby greatly improving the flatness and smoothness of the floor, ensuring that the construction quality reaches higher standards; at the same time, it can help to form a more uniform and delicate texture on the surface of concrete or other materials, so that the two steps of leveling and smoothing can be performed continuously to form an integrated construction, reducing the conversion time during the construction process, and also reducing the frequency and intensity of manual intervention, thereby significantly improving the overall construction efficiency.

[0042] In actual use, by setting up a scraping mechanism, it is convenient to use the scraper 12 and the shovel blade 13 to perform secondary leveling on the smoothed ground, avoiding the accumulation or hardening of residual materials produced during leveling on the ground. This not only helps to keep the ground clean and tidy, but also helps to accurately control the thickness of the ground material layer, avoiding local excessive thickness or thinness, ensuring that the entire ground is flat and consistent, making the ground flatness more accurate, and there is no need for construction workers to interrupt work to manually clean up excess materials, and the use effect is good.

[0043] like Figure 2 As shown, in this embodiment, the width adjustment mechanism includes a fixed plate 19 connected to the lower end of the pull rod 10, and two vertical rods 17 and two cross rods 18 arranged in a crisscross shape and respectively connected to different sides of the fixed plate 19, a mounting block 16 is provided on the rear connecting rod 15, one end of the two vertical rods 17 are connected to the mounting block 16, sliders 20 are provided at both ends of the cross rod 18, and a second sliding groove 23 for the sliding movement of the slider 20 is provided on the second extension rod 22.

[0046] In this embodiment, a handle 11 is provided at the upper end of the pull rod 10 .

[0047] During actual use, the first slide groove 9 and the second slide groove 23 are parallel to each other, and the lengths of the first slide groove 9 and the second slide groove 23 are equal, so that construction workers can pull the handle 11 to make the pull rod 10 drive the fixed plate 19 to move, and then drive the slider 20 to slide on the second extension rod 22, and then drive the shovel blade 13 to move, so that the shovel blade 13 pushes the concrete debris between the scraper 12 and the protective shell 1, avoiding the influence of excess concrete debris on the movement of the scraper 12.

[0048] In this embodiment, the protective shell 1 includes a top plate 24 and a bottom ring 25 . The top plate 24 and the bottom ring 25 are connected by a plurality of protective rods 26 . The other end of the second extension rod 22 is connected to the top plate 24 .

[0049] During actual use, the motor protective shell 2 is located at the center of the top plate 24, so that multiple scrapers 27 are also located at the center of the top plate 24, and the top plate 24 is a circular plate with a diameter larger than the rotation area of ​​the scraper 27, which is convenient for forming a cylindrical protective shell 1. It can not only prevent the concrete debris produced by the scraper 27 from splashing indiscriminately, but also protect construction workers from the rotating scraper 27, and has strong safety.

[0051] In this embodiment, the guard plate 5 is an arc-shaped plate, and the lower surface of the guard plate 5 is higher than the upper surface of the scraper 27 .

[0052] In actual use, by setting up the guard plate 5, it is convenient to prevent flying stones, debris or other sundries from causing harm to on-site workers, greatly improving the safety of the construction site, and also preventing excess materials and dust generated during the leveling process from spreading to the surroundings, limiting their impact range, thereby significantly reducing the workload of cleaning after construction and improving work efficiency. In addition, the guard plate 5 can effectively prevent cement slurry, mortar and other building materials from causing pollution or damage to walls, decorated floors or facilities.

[0053] It should be noted that the support rod 3 and the pull rod 10 are both in an inclined state, which makes it convenient for construction workers to stand on the side of the guard plate 5 away from the protective shell 1 and pull the support rod 3 backward.

[0054] When the utility model is used, after the concrete floor is paved, the drive motor 29 is turned on, so that the multiple scrapers 27 start to rotate, and the concrete surface is scraped and leveled by friction. At the same time, the construction personnel pull the support rod 3 to move backward, so that the scrapers 27 gradually smooth the entire floor, and also drive the scraper 12 to move backward to level the floor for the second time, and by pulling the pull rod 10 backward, the shovel blade 13 is driven to collect the debris on the concrete floor.

[0055] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
