The marking device is in contact with the vehicle, and the air valve (equivalent to a pneumatic valve) that controls the movement of the marking device moves. The feed pipe transports hot melt to the marking mechanism, and the vehicle moves forward to start the marking operation. At the same time, the roller brush motor is controlled to work, and the roller brush motor drives the central axis of the roller brush to rotate, so that the roller brush rotates to clean the road, ensuring that the road surface in front of the marking mechanism is clean. The marking mechanism evenly applies the hot melt on the road. The two marking mechanisms can work at the same time, so that two marking lines can be drawn at one time, and the marking efficiency is high. The heat transfer oil pipe injects high-temperature heat transfer oil into the heat transfer ring cavity in the pipe wall of the feed pipe, thereby heating the hot melt in the feed pipe, ensuring that the hot melt entering the marking mechanism is kept warm, and the fluidity of the hot melt remains good.

[0017] It should be noted that the swing arm assembly in the present invention is composed of four swing arms, a parallelogram composed of the upper swing arm, the lower swing arm, the upper swing arm and the lower swing arm. The lower swing arm cylinder drives a set of diagonals of the parallelogram, which makes it easier to achieve telescopic and rotational movements. In addition, the parallelogram structure is also a key factor in preventing disordered movement of components connected to the lower part of the lower swing arm assembly.

[0018] The invention has scientific design and simple structure, can mark two marking lines at one time, has high marking efficiency, ensures the heat preservation of the hot melt entering the marking mechanism, and keeps the fluidity of the hot melt good. BRIEF DESCRIPTION OF THE DRAWINGS
