At this time, the tension generated by the second spring rod will cause the first piston plate, the cross bar and the second piston plate to move, so that the first piston plate can block the connection between the adapter box and the first nozzle, and the second piston plate no longer blocks the connection between the second nozzle and the adapter box, then the maintenance material inside the adapter box will be sprayed out from the second nozzle, so as to realize the switching of the nozzles on the same adapter box, thereby ensuring the smoothness and stability of the operation of the maintenance equipment and avoiding the situation that the highway cannot be evenly maintained after the first nozzle is blocked;

[0024] S4: In addition, when the second piston plate moves, it will drive the top end of the indicator rod to move out of the adapter box, so as to remind the staff that the first nozzle of the adapter box is blocked. In summary, the highway can be maintained evenly and stably.

[0047] Working principle of the present invention:

[0048] First, the vehicle body 1 is moved onto the road and then the vehicle body 1 is moved, and the maintenance material in the tank body 2 is pumped into the pipe body 3 (a pump body connected to the connecting pipe is installed inside the tank body 2), and the solenoid valve 9 is opened simultaneously, so that the maintenance material in the tank body 2 will enter the pipe body 3 from the connecting pipe, and the maintenance material in the pipe body 3 will pass through the connecting pipe 8 and the adapter box 4 and be sprayed out from the first spray pipe 5 to maintain the road;

[0049] When the maintenance material is sprayed out from the first nozzle 5, it will impact the disc 21 and make the disc 21 move downward. The disc 21 moves downward and drives the connecting rod 12 to move downward. The connecting rod 12 moves downward and drives the connecting plate 10 to move downward, and the first spring rod 11 generates elastic force. The connecting plate 10 moves downward and drives the connecting plate 13 to move downward. The connecting plate 13 moves downward and drives the third spring rod 22 to move downward.

In summary, the highway maintenance can be achieved.

[0050] When the first nozzle 5 is blocked, the maintenance material no longer impacts the disc 21, and the elastic force generated by the first spring rod 11 causes the connecting plate 13 and the connecting rod 12 to move upward, and the upward movement of the connecting plate 13 drives the third spring rod 22 to move upward, and the upward movement of the third spring rod 22 drives the sleeve plate 24 to move upward, and the upward movement of the sleeve plate 24 drives the telescopic end of the fourth spring rod 23 and the locking block 25 to move upward, so that the fixing of the locking plate 19 is released. At this time, the tension generated by the second spring rod 16 causes the first piston plate 14, the cross bar 18 and the second piston plate 15 to move, so that the first piston plate 14 can block the connection between the adapter box 4 and the first nozzle 5, and the second piston plate 15 no longer blocks the connection between the second nozzle 6 and the adapter box 4, then the maintenance material inside the adapter box 4 will be sprayed out from the second nozzle 6, so that the nozzles on the same adapter box 4 can be switched, thereby ensuring the smoothness and stability of the operation of the maintenance equipment, and avoiding the situation that the highway cannot be evenly maintained after the first nozzle 5 is blocked;

[0051] In addition, when the second piston plate 15 moves, it will drive the top of the indicator rod 17 to move out of the adapter box 4, which is used to remind the staff that the first nozzle 5 of the adapter box 4 is blocked.
