Large-area vibrating and polishing device

The large-area vibrating and polishing device comprises a vibrating panel, a mounting frame is fixedly connected to the vibrating panel through a first connecting piece, a mounting plate is fixedly connected to the mounting frame through a second connecting piece, and a supporting plate is fixedly connected to the top of the mounting plate through a stand column. An oil tank is fixedly installed at the top of the supporting plate, a diesel vibration machine is fixedly installed on the side face of the oil tank, a pull rope starter used in cooperation with the diesel vibration machine is installed on the diesel vibration machine, a metal framework is fixedly connected to the top of the mounting frame through two holding rods, and supporting rods are symmetrically installed on the metal framework. The diesel vibration machine is higher in vibration frequency, the proper vibration frequency can be selected, the slurry extracting and surface finishing effect can be better achieved during concrete leveling, the co
