[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a road marking device for municipal roads.

[0035] Reference Figure 1 and Figure 2A municipal road marking device includes a mobile body 100, a material storage box 200 is fixedly connected to the mobile body 100, the material storage box 200 is arranged horizontally, a partition plate 210 is installed in the material storage box 200, and the partition plate 210 divides the material storage box 200 into two left and right material storage chambers 220, one of which is used to hold yellow paint, and the other is used to hold white paint. Two groups of paint mechanisms 300 are installed on the mobile body 100, and the two groups of paint mechanisms 300 are arranged in a one-to-one correspondence with the two material storage chambers 220. The paint mechanisms 300 are used to spray the paint in the corresponding material storage chambers 220 onto the road. When the mobile body 100 is pushed to move to draw lines on the road, different paint mechanisms 300 are activated as the mobile body 100 moves, and line markings of corresponding colors can be sprayed on the road. There is no need to operate two line drawing devices, which improves the convenience of road line drawing construction.

[0036] Reference Figure 1 and Figure 3 Each coating mechanism 300 includes a discharge pipe 310 fixedly connected to the storage box 200, one end of the discharge pipe 310 is connected to the storage chamber 220, and the other end of the discharge pipe 310 is connected to a spray gun 320, and the spray gun 320 faces the road surface.

[0037] The mobile body 100 is equipped with an adjustment mechanism 400, which includes an adjustment plate 410 hinged on one side of the mobile body 100. The hinge axis of the adjustment plate 410 and the mobile body 100 is horizontally arranged. The hinge point of the adjustment plate 410 and the mobile body 100 is located near the middle of the adjustment plate 410. The two spray guns 320 are fixedly connected to the adjustment plate 410, and the two spray guns 320 are respectively located near the two ends of the adjustment plate 410. The mobile body 100 is equipped with a driving member 420, which is used to drive the adjustment plate 410 to rotate.

[0038] Reference Figure 1 and Figure 3The driving member 420 includes an electric push cylinder 421 fixedly connected to the mobile body 100, the piston rod of the electric push cylinder 421 is fixedly connected to a rack 422, the length direction of the rack 422 is parallel to the extension and retraction direction of the piston rod of the electric push cylinder 421, the rack 422 is slidably connected to the mobile body 100, and a gear 423 is fixedly connected to the adjusting plate 410, the axis of the gear 423 is colinear with the hinge axis of the adjusting plate 410, and the gear 423 is meshingly connected to the rack 422. By installing the two spray guns 320 at positions close to the two ends of the adjustment plate 410 respectively, when painting lines on the road, the electric push cylinder 421 is started according to the color requirements of the line markings, and the rack 422 is driven to slide by the electric push cylinder 421, and the adjustment plate 410 can be driven to rotate through the cooperation of the gear 423 and the rack 422. When it is necessary to paint white or yellow markings, the corresponding spray gun 320 can be driven downward; when it is not necessary to paint lines on the road, the two spray guns 320 can be raised to reduce the possibility of collision between the spray guns 320 and obstacles on the road surface.

The air outlet of the air outlet pipe 530 faces the paint just sprayed on the road surface. After the road is marked, the hot air blower 510 will simultaneously supply air to the air outlet duct 530, so that the hot air is blown out from the air outlet of the air outlet duct 530 and blown onto the newly marked road line, so that the newly marked road line can be quickly dried. At the same time, since the hot air blown out by the hot air blower 510 will first pass through the heating network pipe and then enter the air outlet duct 530, the heating network pipe can heat the paint at the bottom of the storage box 200, reducing the possibility that the paint has poor fluidity in severe cold weather and affects the paint spraying effect.
