[0025] It can be understood that the equipment main body 1 can hold asphalt, can move automatically, or move under the action of external force, and the equipment main body 1 can supply asphalt to the metering nozzle assembly 4. During the walking process, the metering nozzle assembly 4 can spray asphalt quantitatively. The connecting seat 2 and the connecting assembly 3 cooperate to stably hold the metering nozzle assembly 4, so that during the spraying process, the metering nozzle assembly 4 will not shift or shake, so as to make the thickness of the asphalt spraying uniform and the spraying accuracy high.

[0026] Please refer to Figure 2 , in some embodiments, the connecting seat 2 includes a stabilizing rod 201 and a limiting rod 202. The limiting rod 202 is connected to the equipment main body 1 through the stabilizing rod 201, and the connecting assembly 3 is connected to the limiting rod 202.

[0027] It can be understood that the number of the stabilizing rods 201 can be two, which can be vertically welded to the equipment main body 1. The limiting rod 202 can be vertically welded to the stabilizing rod 201. The limiting rod 202 can fixedly connect the connecting assembly 3 and limit the movement of the connecting assembly 3, so as to improve the stability of the connection of the metering nozzle assembly 4.
