[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rotating blade assembly includes: a motor 20, a first rotating shaft 21 disposed below the motor 20, the first rotating shaft 21 being cylindrical, and multiple first rotating shafts 21 being uniformly fixedly connected to the arc surface of the first rotating shaft 21; the motor 20 being electrically connected to a corresponding power source, which is existing technology and will not be described in detail here.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the obstacle removal structure is installed on the wall of the motor 20 to remove impurities in front. The obstacle removal structure includes: a box body 30, a second rotating shaft 31, a second blade 32, a wind plate 33, and an air outlet plate 34. The motor 20 is fixedly connected to the top of the box body 30, the second rotating shaft 31 is symmetrically rotatably connected to the bottom of the box body 30, the second blade 32 is fixedly connected to the wall of the second rotating shaft 31, the wind plate 33 is fixedly connected to the top of the second blade 32, and the air outlet plate 34 is fixedly connected to the front wall of the box body 30.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the box body 30 is a bullet-shaped hollow box with an open bottom. The second rotating shaft 31 and the first rotating shaft 21 are rotatably connected to the bottom cavity of the box body 30. A motor 20 is installed at the top of the box body 30 above each of the second rotating shafts 31 and the first rotating shaft 21. Each corresponding motor 20 can drive the corresponding second rotating shaft 31 and the first rotating shaft 21 at the bottom to rotate. The second rotating shaft 31 is cylindrical, similar to the first rotating shaft 21. Multiple identical second rotating shafts 31 are arranged in a circular array on the arc surface of each second rotating shaft 31. The second blade 32 is a rectangular plate. The top of each second rotating shaft 31... The same second blade 32 is fixedly connected to each other. The front wall of the box body 30 has a rectangular opening. The air outlet plate 34 is a rectangular plate and is located in the opening on the front wall of the box body 30. Multiple round holes are opened through the front wall of the air outlet plate 34. Multiple rectangular grooves are opened in the top of the cavity of the box body 30. The obstacle clearing structure also includes inclined plates 35. The inclined plates 35 are symmetrically fixedly connected to both sides of the rear wall of the box body 30. The rear wall of the box body 30 is in an open state. The inclined plates 35 are rectangular plates. Each inclined plate 35 is placed obliquely on both sides of the box body 30. A rectangular opening is opened at each inclined plate 35 on both sides of the box body 30.

[0032] In practical use, the power to the motor 20 is turned on. The motor 20 drives the corresponding second rotating shaft 31 and first rotating shaft 21 at the bottom to rotate. The second rotating shaft 31 and first rotating shaft 21 on the left side will rotate counterclockwise, and the second rotating shaft 31 and first rotating shaft 21 on the right side will rotate clockwise. When the first rotating shaft 21 rotates, it drives the first blade 22 to rotate, and the second rotating shaft 31 drives the second blade 32 to rotate. The rotating second blade 32 and first blade 22 can scrape and remove the markings on the ground. When the second blade 32 rotates, it will drive the top air plate 33 to rotate. The rotating air plate 33 can create a suction effect and blow the air from back to front. The rearward air can enter the cavity of the box 30 through the openings on the side walls of the box 30 at the inclined plates 35 on both sides. Then, the rotating air plate 33 drives the air in the cavity of the box 30 to move forward. Finally, the air will pass through the round hole on the wall of the air outlet plate 34. At this time, the air blown out by the air outlet plate 34 will automatically blow away the stones or impurities in front of the air outlet plate 34, so that the stones and impurities are separated from the top of the marking line.

[0033] In summary, by setting up a clearing structure, the high-speed rotating second blade 32 drives the air plate 33 to pass through the cavity of the box 30 and automatically blow away the stones and impurities above the marking line from the air outlet plate 34. This not only clears the marking line, but also automatically cleans the top of the marking line along the way, eliminating the need for workers to manually clean the marking line beforehand.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the wall of the box 30 is provided with a water spray structure, which includes a shower head 40, a water guide pipe 41, and a guide plate 42. The shower head 40 is fixedly connected to the opening on the rear wall of the box 30, the water guide pipe 41 is fixedly connected to the top of the shower head 40, and the guide plate 42 is fixedly connected to the front wall of the shower head 40. The shower head 40 is a rectangular box with a hollow cavity. The water guide pipe 41 is a round pipe. The bottom of the water guide pipe 41 can communicate with the cavity of the shower head 40. Multiple round holes are evenly opened on the front wall of the shower head 40. The guide plate 42 is a rod with a right-angled triangular cross section. The top slope of the guide plate 42 is aligned with the round holes on the front wall of the shower head 40.

[0035] In practical use, when the second blade 32 and the first blade 22 are clearing the markings, the top of the water guide pipe 41 and the water supply pipe are connected. The water supply pipe will inject water into the cavity of the water guide pipe 41. Then the water will pass through the cavity of the shower head 40 and finally spray out forward through the round hole on the wall of the shower head 40. The water sprayed out from the wall of the shower head 40 will come into contact with the rotating second blade 32 and the first rotating shaft 21 to reduce their heat and the dust in the cavity of the box 30. The water mist in the cavity of the box 30 will also be sprayed out towards the air outlet plate 34 as the wind plate 33 rotates.

[0036] In summary, by setting up a water spray structure, not only can the water sprayed by the shower head 40 be used to cool down and reduce dust, but the sprayed water can also be directed to pass through the air outlet plate 34 in conjunction with the air plate 33, thereby enhancing the obstacle removal effect.

[0037] like Figure 1 As shown, a road marking removal machine includes a removal machine 10 and a rotating blade assembly as described above. The bottom of the removal machine 10 is equipped with a bracket for connecting to the top of the housing 30. When in use, the removal machine 10 is pushed on the road surface. The pushed removal machine 10 can drive the housing 30 to move synchronously through the bracket. The moving housing 30 will drive the second blade 32 and the first blade 22 at its bottom to remove the road markings.

[0038] By setting a rotating blade, not only can the markings be cleared, but the top of the markings to be cleared along the way can also be cleared by airflow at the same time, thus avoiding the problem that impurities above the markings will damage the second blade 32 and the first blade 22.

[0039] Working principle: When the power to motor 20 is turned on, motor 20 drives the corresponding second rotating shaft 31 and first rotating shaft 21 at the bottom to rotate. The second rotating shaft 31 and first rotating shaft 21 on the left side will rotate counterclockwise, and the second rotating shaft 31 and first rotating shaft 21 on the right side will rotate clockwise. When the first rotating shaft 21 rotates, it drives the first blade 22 to rotate, and the second rotating shaft 31 drives the second blade 32 to rotate. The rotating second blade 32 and first blade 22 can scrape and remove the markings on the ground. When the two blades 32 rotate, they will drive the top air plate 33 to rotate. The rotating air plate 33 can create a suction effect and blow the air from back to front. The rearward air can enter the cavity of the box 30 through the openings on the side walls of the box 30 at the inclined plates 35 on both sides. Then, the rotating air plate 33 drives the air in the cavity of the box 30 to move forward. Finally, the air will pass through the round hole on the wall of the air outlet plate 34. At this time, the air blown out by the air outlet plate 34 will automatically blow away the stones or impurities in front of the air outlet plate 34, so that the stones and impurities are separated from the top of the marking.
