Raw material screening equipment for municipal engineering construction

The utility model discloses raw material screening equipment for municipal engineering construction, and belongs to the technical field of building equipment. Raw materials are poured into the feeding hopper and fall onto the first-stage sieve plate, then the motor is started, the first-stage sieve plate and the second-stage sieve plate form an up-and-down vibration form through the arranged elliptical wheel, the raw materials can be screened, after screening is completed, the material receiving box is taken out, then the material blocking plug is pulled up, the air cylinder is started, and the bearing plate and all components on the bearing plate are in an inclined state; the raw materials left on the sieve plates can enter the two material collecting boxes, then the air cylinder is started, the bearing plate is reset, and therefore screening work is completed, through the arrangement of the first-stage sieve plate and the second-stage sieve plate, the raw materials can be screened more finely according to t
