The invention discloses equipment for automatically screening large-particle-size gravels in dike filling materials and an implementation method. The equipment comprises a transmission mechanism, a walking mechanism, a cab, a storage bin, a screening mechanism and a conveying mechanism. The transmission mechanism is used for being responsible for overall operation of mechanical equipment. The walking mechanism is used for being responsible for mechanical driving. The cab is used for mechanical operation control; the storage bin is used for storing the screened large-particle-size gravels and pebbles; a material shoveling plate in the screening mechanism is responsible for shoveling the paved gravel and pebble materials, a rotary cutter head is responsible for feeding the gravel and pebble materials shoveled by the material shoveling plate into a roller conveying belt for screening, and the roller conveying belt is used for particle size screening and conveying; a screw elevator in the conveying mechanism conveys the screened large-particle-size gravels to a conveying belt through a screw blade, and the conveying belt conveys the large-particle-size gravels into a storage bin. The equipment is simple in structure, high in functionality, high in automation degree and high in practical value, the construction efficiency can be greatly improved, the construction progress can be accelerated, and the construction quality can be improved.
