[0030] The working principle of the above embodiment is:

[0031] (1) When the barrier arm is raised or lowered, the hydraulic cylinder 303 is first opened, and the output shaft of the hydraulic cylinder 303 drives the connecting block 304 to move, the connecting block 304 drives the pin 305 to move, the pin 305 drives the connecting plate 306 to rotate, the connecting plate 306 rotates and drives the active connecting rod 307 to rotate, the active connecting rod 307 drives the first sleeve 308 to rotate, the first sleeve 308 drives the active linkage plate 310 to rotate, the active linkage plate 310 drives the support rod 4 to move, so that the support rod 4 drives the barrier arm assembly 5 to move, so as to drive the barrier arm to be raised or lowered.

[0032] (2) During the lifting and lowering of the support rod 4, the linkage block 311 will be driven to move, and the linkage block 311 will drive the driven linkage plate 312 to rotate, and the driven linkage plate 312 will drive the second sleeve 313 to rotate, so that the driven connecting rod 314 will rotate on the driven shaft 315, so that the blocking arm will remain in a vertical state during the movement. When the blocking arm rises, the blocking wheel 502 can contact the drum wheel in the follower shaft at the lower end of the moving swing bracket assembly to promote the relative rotation angle change of the swing bracket assembly. When the blocking arm descends, the blocking wheel 502 is located below the drum wheel in the follower shaft and cannot form contact adjustment. The lower end of the swing bracket assembly can pass through the filling position without interference, thereby facilitating the automatic filling of the slag plug. The motion system of the blocking wheel 502, the self-lubricating bearing 503, and the core shaft 504 can ensure that the rotation angle change process of the swing bracket assembly is smooth.
