The utility model provides a screening device with a dust suppression structure, and relates to the technical field of screening devices, the screening device comprises a box body, a
fixed frame is fixedly installed on the surface of the box body, a
vibration motor is fixedly installed on the surface of the
fixed frame, a screen plate is placed on the surface of the
fixed frame, and a sliding groove is formed in the surface of the box body. By arranging the box body, the fixing frame, the
vibration motor, the screen plate, the sliding groove, the sliding plate, a dust suction cover, an air bellow, a dustproof plate, a collecting box, an
exhaust pipe and a discharging port structure, when the screening device is used, the sliding plate can be closed in a sliding mode, dust splashing can be effectively prevented,
pollution is avoided, meanwhile, when the air bellow is started, the air bellow is prevented from falling off, and the screening device is convenient to use. And dust can be sucked into the air bellow from the interiors of the dust suction hoods along the
exhaust pipe, the dust suction area can be increased through the two dust suction hoods, dust suction can be conducted on the interior of the box body more effectively, and the situation that the dust flows out of the box body and harms the environment and the
human body is further prevented.
