Referring to the patent application with reference to publication number CN217247278U, a recycled asphalt concrete mixing equipment aggregate recovery device is disclosed. The gear is driven to rotate by a rotating motor, and the flow limiting plate can be driven to rotate through the engagement of the gear and the arc-shaped rack, so that the flow limiting plate and the through groove are staggered with each other.

[0026] The dust removal component 22 is arranged at the front side of the box body 1 and is used to collect dust generated during screening. The bottom surface of the feed hopper 211 penetrates the box body 1 and the top surface of the fixed cylinder 212 and extends to the inside of the fixed cylinder 212. The output end of the drive motor 214 movably penetrates the left end of the fixed cylinder 212 and is fixedly installed on the left end of the shaft 215. Starting the drive motor 214 can drive the shaft 215 to make a plurality of scrapers 213 screen the aggregate.

When in use, the fan 226 is started to suck the dust generated during screening by the screening assembly 21 into the interior of the installation box 221 through the ventilation slot 224. When the dust enters the interior of the installation box 221, it will be intercepted by the filter 225 and adhere to one side of the filter 225, thereby preventing the dust from spreading and affecting the health of the operator and polluting the working environment.

The discharge device, then the reciprocating vibrator 2110 is started to drive the sieve plate 219 up and down. The aggregate is vibrated to be screened again. At this time, smaller aggregates will be screened by the sieve plate 219 and discharged from the device through the discharge port 2113, while medium-sized aggregates will be discharged from the device from the second discharge hopper 2111 through the sieve plate 219. At the same time, the fan 226 is started to suck the dust generated by the screening component 21 during screening into the installation box 221 through the ventilation slot 224. When the dust enters the interior of the installation box 221, it will be intercepted by the filter 225 and adhere to one side of the filter 225. When the filter 225 needs to be cleaned, the handle 223 can be pulled out of the installation box 221 through the slot 222 for cleaning.
