[0025] like Figure 1 As shown, this embodiment discloses a road marking device for marking a road surface. The road marking device includes a base 10, a stirring mechanism 20, a marking mechanism 30, a driving mechanism 40 and a blowing mechanism 50, which are specifically described as follows:

[0026] like Figure 2As shown, the base 10 is a carrier of each component. A plurality of running wheels 10a are arranged at the lower end of the base 10. The plurality of running wheels 10a are arranged in a triangle below the base 10. The base 10 moves on the road surface through the running wheels 10a. Because the triangle has a certain stability, the base 10 can be moved in a straight line as much as possible when it moves, thereby increasing the accuracy of marking. A handle is provided on one side of the base 10, and the handle facilitates pushing the base 10 forward. The base 10 can move in a straight line in the first horizontal direction through the running wheels 10a.

[0027] like Figure 3 As shown, the stirring mechanism 20 includes a plurality of stirring barrels 21 (two stirring barrels are shown in the present embodiment) and a plurality of stirring blades 22. The stirring barrels 21 are arranged on the base 10 at intervals along a second horizontal direction. The second horizontal direction intersects the first horizontal direction vertically in a horizontal plane. Paints of different colors are arranged in the stirring barrels 21. The plurality of stirring blades 22 are rotatably arranged in the stirring barrels 21 in a one-to-one correspondence. The stirring blades 22 are used to stir the paint in the stirring barrels 21.

The paint in the mixing barrel 21 can be transported to the marking nozzle 33 through the connecting pipe 31. The marking nozzle 33 is installed at the bottom of the base 10, and the marking nozzle 33 faces the road surface. The marking nozzle 33 sprays paint to achieve marking; the control valve 32 is set on the connecting pipe 31 in a one-to-one correspondence, and the control valve 32 controls the circulation of the paint in the connecting pipe 31, thereby controlling the spraying of paint of different colors from the marking nozzle 33. The specific structural form of the marking nozzle 33 can refer to the prior art.

[0030] like Figure 1As shown, the driving mechanism 40 includes a mounting plate 41 and a driving unit 42; the mounting plate 41 is rotatably connected (hinged) to the base 10, and the mounting plate 41 is hinged to the base 10 to facilitate adjustment of the position of the driving unit 42, and to make room for adding paint to the mixing barrel 21. It should be noted that the mounting plate 41 can be directly hinged to the base 10, or can be hinged to the base 10 through other structures. In this embodiment, it is preferred that the mounting plate 41 is hinged to the base 10 through other structures. As follows: the driving mechanism 40 also includes an articulated block 43 and a support block 44, the lower end of the articulated block 43 is fixed to the edge of the upper surface of the placement box 23, the lower end of the support block 44 is also fixed to the edge of the upper surface of the placement box 23, and the articulated block 43 and the support block 44 are arranged relatively spaced along the second horizontal direction, one end of the mounting plate 41 is hinged to the upper end of the articulated block 43 through a pin, and the other end of the mounting plate 41 can be rotatably mounted on the support block 44, and when the mounting plate 41 is mounted on the support block 44, the mounting plate 41 is just in a horizontal state. The articulated block 43 and the support block 44 designed in this embodiment can provide an articulated position for the mounting plate 41, and can also support the mounting plate 41.

It should be noted that in some other embodiments, other structures that can realize the slidable arrangement of the driving unit 42 along the second horizontal direction can also be adopted between the driving unit 42 and the mounting plate 41.

[0032] In this embodiment, the driving unit 42 can change its working position, and then can be connected to any stirring blade 22 in the stirring barrel 21, so as to drive the stirring blade 22 to stir the paint in the stirring barrel 21. Further, when the working position of the driving unit 42 needs to be changed, it is only necessary to rotate and lift the mounting plate 41, and after adjusting the position of the driving unit 42 by sliding the first slider 411, rotate the mounting plate 41 and place it on the supporting block 44, and then connect the driving unit 42 to the stirring blade 22.

[0033] In some preferred solutions, the first slider 411 and the mounting plate 41 may be compressed together by compression bolts (not shown), thereby ensuring the stability of the first slider 411 and the driving unit 42 during operation.

[0034] In some preferred schemes, a cushion layer (such as rubber, not shown) is provided on the upper surface of the first slider 411. The cushion layer is located between the first slider 411 and the driving unit 42. The driving unit 42 contacts the first slider 411 through the cushion layer. The cushion layer is designed to absorb the vibration generated when the driving unit 42 is working, reduce the vibration of the device, and ensure accurate marking.

[0035] like Figure 3 As shown, in some preferred schemes, the detachable connection between the output end 421 of the driving unit 42 and the stirring blade 22 can be a snap-on connection or a bolt connection. In this embodiment, a bolt connection is adopted, which is as follows: a mounting slot is coaxially arranged on the lower end face of the output end 421 of the driving unit 42, and the inner diameter of the mounting slot is larger than the outer diameter of the connecting shaft 221 of the stirring blade 22. When connected, the mounting slot is sleeved on the outer periphery of the connecting shaft 221, and corresponding mounting holes are arranged on the outer periphery of the output end 421 and the outer periphery of the connecting shaft 221. The first bolt 45 is penetrated and connected in the mounting hole to realize a stable connection between the output end 421 of the driving unit 42 and the connecting shaft 221.

[0036] like Figure 1 and Figure 5 As shown, the blowing mechanism 50 includes an air blowing mechanism 51 and a brush mechanism 52. The air blowing mechanism 51 can blow air toward the road surface, and the brush mechanism 52 is used to brush the road surface.

[0037] like Figure 1 As shown, the blowing mechanism 51 includes a fan 511 and a blowing pipe 512; the fan 511 is arranged on the upper surface of the base 10, the output end of the fan 511 is connected to one end of the blowing pipe 512, and the other end (the air outlet end) of the blowing pipe 512 extends to the bottom of the base 10, which is used for blowing and cleaning the road surface.

[0038] like Figure 5 As shown, the brush mechanism 52 includes a brush 521, which is disposed below the base 10. The brush 521 contacts the road surface, thereby brushing the road surface before marking.

[0039] It should be noted that along the first horizontal direction (i.e., the movement direction of the base 10), the marking nozzle 33, the other end of the blowing tube 512 and the brush 521 are sequentially arranged below the base 10, which can achieve the effect of brushing first, then blowing and finally marking, thereby improving the quality of marking.

[0040] like Figure 5 As shown, in some preferred solutions, the brush mechanism 52 also includes a second slider 522 (rectangular block) and an adjusting screw 523; wherein the base 10 is provided with a second slide groove 10b along the second horizontal direction, the upper end of the second slider 522 is provided in the second slide groove 10b, the second slider 522 can only slide in the second slide groove 10b along the second horizontal direction, and the brush 521 is connected to the second slider 522; the adjusting screw 523 is rotatably provided below the base 10, the adjusting screw 523 passes through the second slider 522, and the adjusting screw 523 is threadedly matched with the second slider 522, wherein the axial direction of the adjusting screw 523 is configured as the second horizontal direction, and when the adjusting screw 523 is rotated, the second slider 522 and the brush 521 can change position in the second horizontal direction. In this embodiment, by providing the adjusting screw 523 and the second slider 522, the position of the brush 521 can be adjusted, so as to facilitate the adjustment of the cleaning position according to the actual working conditions.

[0041] like Figure 5 As shown, in some preferred schemes, the lower end surface of the second slider 522 is provided with a concave rectangular groove, and the side wall of the second slider 522 is provided with a plurality of first connecting holes 522a distributed along the height direction, one end of the brush 521 is inserted into the rectangular groove, and one end of the brush 521 is provided with a second connecting hole 521a. When it is necessary to connect the second slider 522 and the brush 521 together, it can be achieved by passing the second bolt 524 through the first connecting hole 522a and the second connecting hole 521a, and the plurality of first connecting holes 522a can facilitate the selection of the installation position of the brush 521, and then the installation height of the brush 521 can be adjusted. When the brush 521 is not in use, the brush 521 is raised to realize the storage function of the brush 521.

[0042] The working principle and use process of the marking device in this embodiment are as follows:

[0043] Preparation:

[0044] The mounting plate 41 is rotated upwards and the two mixing barrels 21 are inserted into the placement box 23, and the two connecting pipes 31 are respectively inserted into the two mixing barrels 21, and the mounting plate 41 is rotated downwards, and the driving unit 42 is connected to the mixing blades 22 in the mixing barrels 21, and then the driving unit 42 is started to drive the mixing blades 22 to rotate and stir the paint in the mixing barrels 21 to prevent the paint from solidifying. During the marking process, if it is necessary to stir the paint in another mixing barrel 21, the connection between the driving unit 42 and the mixing blades 22 is released, and then the mounting plate 41 is lifted again and the position of the driving unit 42 is slidably adjusted, and then the driving unit 42 is connected to the mixing blades 22 again;

[0045] After selecting the installation position of the brush 521 on the second slider 522, the brush 521 is fixedly installed on the second slider 522, and then the position of the brush 521 is adjusted to the front of the marking nozzle 33 by driving the adjusting screw rod 523;

[0046] Start working:

[0047] The fan 511 is started to blow the road surface, and then the staff pushes the base 10 forward along the first horizontal direction to mark the road surface. In this process, the brush 521 and the air pipe 512 first clean the road surface, and then the paint in the mixing barrel 21 is transported to the marking nozzle 33 through the connecting pipe 31 and sprayed toward the road surface to mark the road surface. When it is necessary to switch to different colors of paint, it is only necessary to control the flow of paint in the connecting pipe 31 through the control valve 32.
