Simple device integrating aggregate screening, cleaning and drying and using method thereof

The invention provides a simple device integrating aggregate screening, cleaning and drying and a using method thereof, and relates to the field of civil engineering indoor tests. The device comprisesfive systems of a variable frequency transmission system, an aggregate screening system, a waste collection system, an ultrasonic cleaning system and a drying system. During tests, vibration force isfirst applied to the aggregate screening system by the variable frequency transmission system, a sieve plate in the aggregate screening system is vibrated up and down, so that aggregates are screened, after screening is complete, a waste collection cabinet in the waste collection system is taken out, then force is applied to the aggregate screening system by the variable frequency transmission system, the screening system is lowered into an ultrasonic cleaning device, the screened aggregates are cleaned, and after the aggregates are cleaned, the variable frequency transmission system is turned off, and the aggregate s
