This adjusts the contact area between the elastic ball and the road, thereby adjusting the width of the marking line. The road marking equipment provided by the embodiment of the present invention can conveniently adjust the horizontal height of the marking barrel through the upper and lower adjustment parts, thereby conveniently controlling whether the road marking equipment is marking and adjusting the thickness of the marking line, thereby improving the efficiency of marking.

[0043] See also Figure 1 The present invention provides a road marking device in an embodiment, including an up / down adjustment unit 4 (specifically, a screw slider mechanism), a ball marking unit 3, a movable bracket 1, and a marking barrel 2. The marking barrel 2 is slidably mounted on the movable bracket 1, the marking barrel 2 having marking paint contained therein, and a paint outlet provided at the bottom of the marking barrel 2. The ball marking unit 3 is positioned at the paint outlet and includes an elastic ball 31 (which may be made of an elastic material such as rubber). The elastic ball 31 is rotatably mounted at the paint outlet, with the bottom of the elastic ball 31 protruding outward from the paint outlet. The up / down adjustment unit 4 is positioned between the marking barrel 2 and the movable bracket 1 and is used to adjust the horizontal height of the marking barrel 2.

[0044] The road marking equipment provided in this embodiment is characterized in that a marking barrel 2 is arranged on a movable bracket 1 so as to facilitate the movement of the marking barrel 2, and a paint outlet is provided at the bottom of the marking barrel 2, and a ball marking part 3 is provided at the paint outlet position, and the ball marking part 3 is used to mark the road (the elastic ball 31 in the ball marking part 3 rotates, and the marking line in the marking barrel 2 is adhered to the surface of the elastic ball 31 with paint, and is coated on the road as the elastic ball 31 rotates (rotates due to friction with the road), thereby achieving road marking). The horizontal height of the marking barrel 2 is adjusted by the upper and lower adjusting parts 4, so that when it is necessary to stop the marking action, the horizontal height of the marking barrel 2 only needs to be raised by the upper and lower adjusting parts 4, so that the elastic ball 31 is separated from the road surface and the marking can be stopped. When it is necessary to mark the road, the horizontal height of the marking barrel 2 only needs to be lowered by the upper and lower adjusting parts 4, so that the elastic ball 31 is in contact with the road surface and the marking can be carried out. When the thickness of the marking line needs to be adjusted, it is also only necessary to use the upper and lower adjustment parts 4 to adjust the horizontal height of the marking barrel 2, thereby adjusting the deformation of the elastic ball 31 (when the marking barrel 2 is adjusted downward, the deformation of the elastic ball 31 increases, making the contact area between the elastic ball 31 and the road larger), so as to adjust the contact area between the elastic ball 31 and the road, thereby adjusting the width of the marking line. The road marking device provided by the embodiment of the present invention can conveniently adjust the horizontal height of the marking barrel 2 through the upper and lower adjustment parts 4, thereby conveniently realizing control of whether the road marking device is marking the line and adjusting the thickness of the line, thereby improving the efficiency of marking.

[0045] After adjusting the marking width, to ensure a uniform paint thickness, the amount of paint attached to the elastic rolling ball 31 needs to be adjusted accordingly. To this end, in one embodiment, the rolling ball marking unit 3 further includes a first elastic member 33 and a horizontal baffle 32. The horizontal baffle 32 is positioned at the bottom of the marking barrel 2, with its edge closely attached to the inner wall of the barrel 2, and the top of the elastic rolling ball 31 resting against the bottom surface of the horizontal baffle 32. One end of the first elastic member 33 is connected to the horizontal baffle 32, while the other end is connected to the inner wall of the barrel 2.

[0046] When the road marking equipment is not marking, the edge of the horizontal baffle 32 is in close contact with the inner wall of the marking barrel 2, so that the paint in the marking barrel 2 will not leak out from the paint outlet at the bottom, thereby avoiding paint waste when the road marking equipment is not marking and preventing the paint in the marking barrel 2 from being hardened and expired due to long-term contact with air.

[0047] When the road needs to be marked, the height of the marking barrel 2 is lowered by the upper and lower adjustment parts 4 so that the elastic rolling ball 31 at the bottom abuts against the ground (such as Figure 2As shown in FIG5 , the elastic ball 31 provides a certain supporting force to the horizontal baffle 32, so that the horizontal baffle 32 overcomes the elastic force of the first elastic member 33 (a structure such as a spring or an elastic rope), so that the horizontal baffle 32 moves upward a certain distance relative to the marking barrel 2, so that there is a certain gap between the horizontal baffle 32 and the inner wall of the marking barrel 2, thereby allowing the paint in the marking barrel 2 to flow downward through the gap to the elastic ball 31, so that marking can be performed as the elastic ball 31 rolls.

[0048] When the width of the marking line needs to be adjusted and widened, the height of the marking barrel 2 can be lowered again by using the upper and lower adjustment parts 4, so that the deformation of the elastic rolling ball 31 is increased (such as Figure 4-5 As shown in FIG2 , at this time, the supporting force exerted by the elastic ball 31 on the horizontal baffle 32 becomes greater, thereby increasing the amount of upward movement of the horizontal baffle 32 relative to the marking barrel 2, thereby widening the gap between the horizontal baffle 32 and the inner wall of the marking barrel 2, so that more paint in the marking barrel 2 can flow downward through the gap onto the elastic ball 31, so as to maintain a uniform thickness of the marking paint after widening the marking width.

[0049] On the contrary, when it is necessary to adjust and reduce the marking width, the deformation of the elastic ball 31 can also be reduced, thereby reducing the gap between the horizontal baffle 32 and the inner wall of the marking barrel 2, thereby reducing the paint flowing from the marking barrel 2 to the elastic ball 31, thereby avoiding excessive paint resulting in too thick markings and waste of paint.

[0050] In one embodiment, the rolling ball marking portion 3 further includes two elastic baffles 34 , one end of the elastic baffle 34 is fixed to the inner wall of the marking barrel 2 , the other ends of the two elastic baffles 34 are closed, and the top of the elastic rolling ball 31 rests on the closed position of the elastic baffle 34 .

[0051] like Figure 7-8 As shown, the ball marking portion 3 in this embodiment can not only automatically adjust the paint output according to the width of the marking line to ensure the uniform thickness of the marking paint (including the sealing function of the paint in the marking barrel 2 in the non-marking state), but also, when the elastic ball 31 gives support to the elastic baffle 34, the two elastic baffles 34 bend upward, so that a gap is generated between the two elastic baffles 34, and the paint in the marking barrel 2 flows downward through the gap to the middle top area of ​​the elastic ball 31. Compared with the ball marking portion 3 with a horizontal baffle 32 structure in the previous embodiment (the paint flows downward to the top side of the elastic ball 31), the paint falling on the middle top area of ​​the elastic ball 31 can be more easily evenly dispersed as the elastic ball 31 rotates, and it is less likely to have less paint or a lack of paint in the middle position of the marking line.

[0052] The presence of dust and moisture on the road surface can easily affect the adhesion of the marking paint to the road surface, which can easily reduce the adhesion of the marking paint. In one embodiment, the road marking equipment includes a drying and cleaning unit 5, which is arranged at the bottom of the marking barrel 2. The drying and cleaning unit 5 includes an annular air duct 51, a hot air pipe 53, and a plurality of air outlet channels 52. Among them, the annular air duct 51 is arranged in the inner wall of the paint outlet; one end of the air outlet channel 52 is connected to the annular air duct 51, and the other end of the air outlet channel 52 extends downward to communicate with the outside world; the hot air pipe 53 is connected to the annular air duct 51, and hot air circulates in the hot air pipe 53. The hot air in the hot air pipe 53 can be generated by a hot air blower. By setting up the drying and cleaning part 5, the hot air in the hot air pipe 53 can pass through the annular channel and then flow through the air outlet channel 52, and then spray hot air to the front end of the moving direction of the rolling ball marking part 3 (the front end of the marking direction), thereby cleaning and drying the front road (removing dust and moisture on the road surface) to facilitate the adhesion of the marking paint to the road surface.

[0053] In addition, since the drying and cleaning part 5 is arranged around the periphery of the rolling ball marking part 3, when the rolling ball marking part 3 completes marking the road, the hot air ejected from the air outlet channel 52 at the rear end of the rolling ball marking part 3 in the movement direction can dry the markings on the road surface, accelerate the drying speed of the marking paint, and prevent the markings from being stepped on by pedestrians or run over by vehicles before they are dry, or being washed away by rain, which may cause the markings to be damaged.

[0054] like Figure 2 As shown, in one embodiment, the outlet end of the air outlet duct 52 is tilted outward. By tilting the outlet end of the air outlet duct 52 outward, when the drying and cleaning unit 5 cleans the front area to be marked, dust and other debris on the road surface will be blown away by the hot air output from the air outlet duct 52, without blowing dust from the front onto the marking paint behind, thereby maintaining the cleanliness of the paint.

[0055] like Figure 2-3 As shown in Figures 5-6, in one embodiment, the road marking device further includes an air volume control unit 6, which includes a second elastic member 63, a connecting rope 62, and a control rod 61. The control rod 61 includes a sliding straight rod section and a tapered plug connected to the sliding straight rod section. The sliding straight rod section is slidably arranged in the inner wall of the marking barrel 2 along the vertical direction. The tapered plug is located in the annular air duct 51 and extends downward into the air outlet channel 52. One end of the connecting rope 62 is connected to the control rod 61, and the other end of the connecting rope 62 is connected to the baffle in the rolling ball marking unit 3. The second elastic member 63 is sleeved on the control rod 61, and one end of the second elastic member 63 rests on the inner wall of the annular air duct 51, and the other end of the second elastic member 63 is connected to the control rod 61.

[0056] By setting up the air volume control part 6, when the ball marking part 3 is in a non-working state, the control rod 61 remains in a closed state under the elastic force of the second elastic member 63, that is, the conical plug of the control rod 61 is inserted into the air outlet channel 52, so that the air outlet channel 52 is in a closed state, and then the drying and cleaning part 5 is shut down.

[0057] When it is necessary to mark the road surface, when the ball marking part 3 is in working state, the baffle (horizontal baffle 32 or elastic baffle 34) in the ball marking part 3 moves upward / bends and rotates a certain distance relative to the marking barrel 2, and the control rod 61 is connected to the baffle through the connecting rope 62, so that the control rod 61 overcomes the elastic force of the second elastic member 63 and moves upward a certain distance (this distance increases as the movement distance of the baffle in the ball marking part 3 increases), thereby causing the conical plug at the bottom of the control rod 61 to move upward, so that the air outlet channel 52 is in an open state. And when the marking width is widened, since the amount of upward movement / deformation of the baffle in the ball marking part 3 increases, the amount of upward movement of the control rod 61 becomes larger, thereby causing the conical plug at the bottom of the control rod 61 to be further withdrawn from the air outlet channel 52 (by Figure 3 Status changes to Figure 6 state), further improving the patency of the air outlet channel 52, thereby increasing the output air volume of the air outlet channel 52, so as to ensure the clean and dry road surface and the drying effect of the marking paint after the marking width is widened.

[0058] In one embodiment, a protective structure that is tightened toward the center is provided at the bottom of the paint outlet, and the aperture of the protective structure is smaller than the diameter of the elastic rolling ball 31. By providing the protective structure, the elastic rolling ball 31 is prevented from falling out of the paint outlet.

[0059] In one embodiment, the mobile bracket 1 includes a bracket body 11 and a moving device 12 disposed at the bottom of the bracket body 11. By disposing the moving device 12 at the bottom of the bracket body 11, the movement and use of the road marking device are facilitated.

[0060] In one embodiment, the mobile bracket 1 further includes a guide ring 13, which is fixed to the bracket body 11, and the marking barrel 2 is slidably fitted in the guide ring 13. By providing the guide ring 13, the stability of the marking barrel 2 is improved.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
