[0002] A snow removal vehicle refers to a special vehicle for removing snow, mainly used for cleaning snow on the ground such as urban roads, highways, and airports. Currently, most snow removal vehicles use a vehicle-mounted front-mounted snow removal rolling brush, and the rotating rolling brush is used to clean the snow. As shown in Figure 1 、 Figure 2 , a rolling brush 105 is installed in front of the snow removal vehicle through a rolling brush bracket 104. An installation seat 103 is installed on the rolling brush bracket 104. The rolling brush support wheel 101 is connected to the installation seat 103 through a support frame 102. The rolling brush support wheel 101 plays an auxiliary support role for the rolling brush 105. Since the support frame is fixedly connected to the installation seat, when the snow removal vehicle operates on an uneven road surface, the support frame has no buffering effect, and the rolling brush support wheel cannot automatically adjust its lifting according to the road surface conditions, and it is easy to be damaged during use; after the rolling brush seedlings are worn, the height of the rolling brush support wheel cannot be adjusted to ensure that the rolling brush seedlings are in contact with the ground. Summary of the Invention
