[0029] See also Figures 1 to 6 As shown, according to an embodiment of the present application, a road marking cleaning device is provided, comprising a base plate 1, the bottom surface of the base plate 1 is connected to a rolling assembly, a push rod 5 is installed at one end of the top surface of the base plate 1, a motor 6 is installed at the end of the top surface of the base plate 1 opposite to the push rod 5, a rotating shaft 7 of the motor 6 passes through the base plate 1 and extends to the bottom of the base plate 1, and a grinding disc 8 is fixedly installed at one end of the rotating shaft 7 away from the motor. The road marking cleaning device also includes a dust box 4 and a vacuum pump 2, the dust box 4 is detachably and slidably arranged on the bottom surface of the base plate 1, and an opening is arranged at one end of the dust box 4 close to the grinding disc 8, and the vacuum pump 2 is penetrated on the side wall of the dust box 4 away from the grinding disc 8 to at least be used to suck the debris generated by grinding the grinding disc 8 from the opening into the dust box 4.

[0030] Specifically, when working, first, the road marking cleaning device is moved to the position to be cleaned. Then, after the dust box 4 is installed on the bottom surface of the base plate 1, the motor 6 and the vacuum pump 2 are started, and the push rod 5 is used to apply thrust to the road marking cleaning device so that the road marking cleaning device moves along the marking line to be cleaned. At this time, the grinding disc 8 rotates under the drive of the motor 6, and the grinding disc 8 contacts the marking line so that the marking line is cleaned by the grinding disc 8. When the grinding disc 8 wears and disperses the marking line, a space with an opening is formed between the dust box 4 and the base plate 1. When the vacuum pump 2 is working, the pressure of the space is reduced, so that the opening has a greater adsorption force to the outside world. Under the adsorption effect of the space, the marking line debris that has fallen off is sucked into the dust box 4 by the negative pressure, thereby completing the cleaning of the marking line and the collection of debris. When the road marking line is cleaned, the motor 6 and the vacuum pump 2 are stopped, and then the dust box 4 is removed, and the debris in the dust box 4 is processed.

[0031] In this embodiment, by using the motor 6 and the grinding disc 8 to replace manual cleaning of the road markings, a large amount of labor costs are saved and the cleaning efficiency of the road markings is improved. In addition, the road marking cleaning device is provided with a vacuum pump 2 and a dust collecting box 4, and the vacuum pump 2 is used to negatively adsorb the marking debris to prevent the debris from flying around during the cleaning process, causing the problem of manual secondary cleaning of the debris.

[0032] Furthermore, a slide groove 12 is provided on one of the base plate 1 and the dust box 4, and a latch 13 adapted to the slide groove 12 is provided on the other of the two. The slide groove 12 or the latch 13 provided on the base plate 1 extends from the side close to the push rod 5 to the side close to the motor 6, and the latch 13 can be slidably connected in the slide groove 12.

[0033] Specifically, the bottom plate 1 and the dust box 4 are detachably and slidably connected through the structure of the slide groove 12 and the convex 13, which facilitates the removal of the dust box 4. In addition, the slide groove 12 and the convex 13 have simple structures, which can reduce the production difficulty and production cost of the road marking cleaning device.

[0034] As attached Figure 3 To Attachment Figure 4 As shown, along the first direction of the bottom plate 1 (attached Figure 1 The bottom surface of the bottom plate 1 is provided with two spaced apart sides along the second direction (the second direction) of the bottom plate 1. Figure 1 The dust collecting box 4 includes a shovel plate 16 and a side plate 14. The side plate 14 is arranged around the outer periphery of the shovel plate 16, and the side plate 14 is provided with a clamping protrusion 13 on both opposite sides. The side plate 14 is provided with an opening on the side away from the limiting plate 11, and a pull block 15 is provided on the side of the side plate 14 away from the opening.

[0035] Specifically, when it is necessary to clean the road markings, the two protrusions 13 on the side plate 14 are placed in the two slide grooves 12 on the bottom plate 1, and then the dust box 4 is pushed to contact the limit plate 11 to complete the installation of the dust box 4. When it is necessary to remove the dust box 4, it is only necessary to remove the dust box 4 along the extension direction of the slide groove 12. In this embodiment, the limit plate 11 can limit the position of the dust box 4 to prevent the dust box 4 from being too far back and too far from the grinding disc 8, so that the vacuum pump 2 has a poor adsorption effect on the debris. In this embodiment, the pull block 15 is a force-applying component for the dust box 4, that is, when the dust box 4 needs to be moved, the pull block 15 can be grasped to push the dust box 4 in the second direction or in the direction opposite to the second direction.

[0036] In the present embodiment, when the dust box 4 is mounted on the chute 12, the open end of the dust box 4 just contacts the ground, and will not be subjected to excessive external force applied by the ground, which makes it difficult for the road marking cleaning device to move. In addition, in the present embodiment, a flexible pad 161 is provided on the bottom surface of the dust box 4 close to the grinding disc 8. On the one hand, the flexible pad can avoid a large gap between the dust box 4 and the ground, thereby causing some debris to pass through the gap and cause the debris to fly. On the other hand, the flexible pad 161 has an anti-wear effect, which improves the service life of the dust box 4 and reduces the use cost of the dust box 4 to a certain extent, that is, the flexible pad 161 only needs to be replaced after being worn, without replacing the entire dust box 4. In some preferred embodiments, thanks to the low cost of the rubber pad, the flexible pad 161 at least includes a rubber pad.

[0037] In some embodiments, when the grinding disc 8 is working, the fallen debris may fly out along the tangent direction of the grinding disc 8 under the action of the grinding disc 8, resulting in the debris not being smoothly sucked into the dust collecting box 4, thereby reducing the cleaning efficiency of the road marking cleaning device. Figure 2 and attached Figure 4 As shown, in this embodiment, a U-shaped groove 17 is opened on the base plate 1, and the motor 6 is located at the open end of the U-shaped groove 17. The road marking cleaning device also includes a U-shaped baffle 18, which is detachably inserted into the U-shaped groove 17 to be used to surround the outer periphery of the dust box 4 and the grinding disc 8.

[0038] Specifically, when it is necessary to clean the road markings, the U-shaped baffle 18 is installed in the U-shaped groove 17. At this time, the U-shaped baffle 18 is arranged around the outer periphery of the dust box 4 and the grinding wheel 8. The debris splashed by the grinding wheel 8 is blocked by the U-shaped baffle 18, thereby being blocked in the space surrounded by the U-shaped baffle 18. Subsequently, the debris is adsorbed in the dust box 4 under the adsorption action of the vacuum pump 2, thereby improving the cleaning efficiency of the road marking cleaning device and avoiding the need for workers to perform secondary cleaning of the splashed debris.

[0039] Further, along the height direction of the road marking cleaning device (attached Figure 1 The U-shaped baffle 18 includes a stop section 181 and a limiting section 182 which are connected to each other. The stop section 181 passes through the U-shaped groove 17 to surround the outer periphery of the dust box 4 and the grinding disc 8. The width of at least part of the limiting section 182 is greater than the width of the U-shaped groove 17.

[0040] Specifically, in this embodiment, the height of the U-shaped baffle 18 is lower than the height of the bottom plate 1, that is, when the U-shaped baffle 18 is installed on the U-shaped groove 17, the U-shaped baffle 18 will not be completely pressed on the ground, making it difficult for the road marking cleaning device to move. The limiting section 182 is used to prevent the U-shaped baffle 18 from completely passing through the U-shaped groove 17 under the action of gravity, so that the stopping section 181 is subjected to excessive resistance from the ground, resulting in the road marking cleaning device being unable to move normally. In this embodiment, the limiting section is a rectangular body, and the width L1 of the rectangular body is greater than the width L2 of the U-shaped groove 17, which can stop and limit the U-shaped baffle 18 on the bottom plate 1. It is worth mentioning that in this embodiment, the height of the stopping section 181 should be the same as or lower than the height of the bottom plate 1.

[0041] Furthermore, connecting plates 20 are connected to the two opposite side walls of the U-shaped baffle 18, and a handle 21 is provided on the top surface of the connecting plate 20. When assembling the U-shaped baffle 18, an external force is applied to the handle 21 to lift the U-shaped baffle or place the U-shaped baffle in the U-shaped groove, so as to facilitate the assembly of the U-shaped baffle 18.

[0042] Considering the limited volume of the dust box 4, when the road marking cleaning device is working for a long time, if the dust box 4 is filled with marking debris, the marking debris ground by the grinding disc 8 cannot enter the dust box 4, so that the debris falls on the ground, which will cause the problem of needing to clean the debris twice. Therefore, in this embodiment, an observation slot 9 is provided on the top surface of the bottom plate 1, and a transparent plate 10 is installed in the inner seal of the observation slot 9. The observation slot 9 and the transparent plate 10 can observe the situation of the dust box 4. For example, when it is observed through the observation slot 9 and the transparent plate 10 that the dust box 4 is full, the operator can stop the road marking cleaning device at this time, remove the dust box 4, and deal with the debris in the dust box 4 before cleaning the road marking. It can be understood that the suction port of the vacuum pump 2 in this embodiment should be set on the side of the dust box 4 close to the top to avoid debris blocking the suction port, and a filter screen or other structure can be set at the suction port to filter the dust.

[0043] Furthermore, the rolling assembly includes a plurality of rollers 3, and the plurality of rollers 3 are rotatably mounted on the base plate 1. In a specific embodiment, the rollers 3 include four rollers 3, and the four rollers 3 are rotatably connected to the four corners of the base plate 1, respectively, to improve the stability of the movement of the road marking cleaning device.

[0044] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0045] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0046] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
