The utility model provides ground polishing equipment. The device is arranged on a frame; polishing device, power device, control device, a first cover is arranged at the bottom of the head of the frame; the first cover narrows and extends towards the bottom of the frame to form a second cover; the first cover and the second cover are connected in a stepped mode. Therefore, a multi-layer shieldingspace is formed. The power device comprises: a power unit; transmission assembly, the driving machine and the transmission assembly are at least partially fixed in the second cover; the driver is fixed at the upper part of the frame body and is in transmission connection with the transmission assembly; the controller is connected with and controlled by the control device; the polishing device comprises a bearing disc and an abrasive disc, the abrasive disc is detachably connected to the bottom of the bearing disc, and the bearing disc is in transmission connection with the transmission assembly to be located below the cage cover of the first cover, so that impact force borne by the polishing device in the machining process is relieved, and therefore the equipment operation difficulty andthe labor intensity of workers are reduced.
