Water washing and screening test device for detecting aggregate raw materials in highway engineering test

The utility model relates to the technical field of road construction, in particular to a highway engineering test detection aggregate raw material washing and screening test device which comprises a support, a vibration mechanism is installed on the top of the support, a screening mechanism is installed above the vibration mechanism, and the screening mechanism comprises a screening drum, a spraying assembly and a cleaning assembly. A first screen plate and a second screen plate are mounted in the screen drum, the spraying assembly sprays and cleans materials placed on the surface of the first screen plate, and the cleaning assembly stirs the materials placed on the surface of the first screen plate; the highway engineering test detection aggregate raw material washing and screening test device has the advantages that in the process that the vibrating mechanism jacks the screen drum to move up and down in a reciprocating mode, materials on the first screen plate are fully cleaned in cooperation with spraying
