Multifunctional shield structure and excavator

The utility model discloses a multifunctional protective cover structure and an excavator. The protective cover structure is formed by integrally assembling a plurality of protective cover componentsside by side. The shield components assembled in a row are installed on the supporting frame and the lower vehicle, and the two sides of the supporting frame are fixedly connected to the lower vehiclethrough fasteners so as to prevent foreign objects from impacting the speed reducer and the hydraulic pipe. The upper tops of the shield components arranged side by side are flush to form a plane walking board, and a space is reserved at the lower end and used for observing the overall working conditions of the speed reducer, the motor and the hydraulic oil pipe. The protective cover structure effectively achieves protection of the speed reducer, the motor and the hydraulic oil pipe, meanwhile can achieve multiple other functions, and is high in overall rigidity, high in stability and convenient to assemble and disass
