The invention discloses a snow shovel for a snow clearer which comprises a push plate, the front side of the push plate is provided with a snow shovel plate, two mounting rods are mounted on the rearside wall of the push plate, the rear side of the push plate is provided with a device groove, the inner wall of the device groove is rotatably connected with a rotating lever, the outer side wall ofthe rotating lever is fixedly connected with a roller. A plurality of device cavities are arranged on both sides of the device groove, the two ends of the rotating rod penetrate a plurality of devicechambers. A cam is fixedly connected to the outer side wall of the rotating lever located in the device cavity, a first abutment lever and a second abutment lever are slidably connected to the inner bottom and the inner top of the device cavity respectively, pulleys are installed at the contact ends of the first abutment lever and the second abutment lever and the cam, and the upper and lower sides of the device cavity are respectively provided with a cavity and a placement groove. The invention has reasonable structure, can crush the ice layer of the pavement, and reduce the integrity of theice block, thereby avoiding the slip phenomenon, sprinkling salt on the pavement at the same time, and effectively preventing the pavement from freezing again.
