[0006] One of the purposes of the present application is to provide a sweeping disc with a rotating joint, comprising a sweeping disc body, a rotating joint body being installed at the center of one side of the sweeping disc body, a ring-shaped movable ring block being arranged on the side of the sweeping disc body close to the rotating joint body, and the movable ring block and the rotating joint body are arranged on a concentric axis, a moving component for driving the movable ring block to move in the axial direction of the rotating joint body is arranged on the sweeping disc body, a plurality of high-pressure nozzles are evenly arranged on the side of the movable ring block away from the sweeping disc body, a hose is fixedly connected to the side of the high-pressure nozzle close to the rotating joint body, one end of the hose is fixedly connected to a high-pressure nozzle, and one end of the high-pressure nozzle is communicated with the rotating joint body.

[0007] As an improvement of the above technical solution: the bottom ends of the plurality of high-pressure nozzles are fixedly connected with a rotating block, the rotating block is rotatably connected with a connecting column, one end of the connecting column is fixedly connected to a side of the movable ring block away from the sweeping disc body.

[0008] As an improvement of the above technical solution: the moving component includes a hydraulic cylinder fixedly installed on the side of the sweeping disc body close to the movable ring block, the output rod of the hydraulic cylinder is fixedly connected to the end surface of the movable ring block away from the high-pressure nozzle, and the side of the sweeping disc body away from the hydraulic cylinder is fixedly connected to a limiting rod, and one end of the limiting rod slides through the movable ring block.

[0009] As an improvement of the above technical solution: there are at least three high-pressure nozzles. When the multiple high-pressure nozzles and the high-pressure nozzle pipe are in the same horizontal plane, the angle between the spray direction of some of the high-pressure nozzles and the movable ring block is 90 degrees, the angle between the spray direction of some of the high-pressure nozzles and the movable ring block is less than 90 degrees, and the angle between the spray direction of some of the high-pressure nozzles and the movable ring block is greater than 90 degrees.

[0010] The second object of the present application is to provide a road cleaning vehicle, which comprises the above-mentioned sweeping disc with a rotary joint, a hydraulic motor and a water pipe, wherein the hydraulic motor is fixedly connected to a side of the sweeping disc body away from the movable ring block.

[0011] Beneficial effects of the utility model:

[0012] When the road is cleaned by a sweeping disc with a rotating joint on a road cleaning vehicle, the controller controls the hydraulic cylinder to repeatedly drive the movable ring block to move upward in both directions of the axis of the rotary joint body, which will synchronously drive multiple high-pressure nozzles connected to the rotating block to move, so that the spray direction of the high-pressure nozzle is closer to the center of the movable ring block. When moving downward, the spray direction of the high-pressure nozzle is further away from the center of the high-pressure nozzle. Therefore, by repeatedly moving up and down, multiple high-pressure nozzles can spray in multiple directions on one side of the movable ring block, thereby increasing the spray range of the high-pressure nozzle, thereby effectively improving the road cleaning effect and efficiency.
