Then, the dust is sucked into the dust collector 3 through the second dust suction pipe 604, and then the dust is sucked into the dust collector 3 through the second dust suction pipe 604. The pipe 605 sucks the dust generated by drying and screening into the dust collector 3, and filters the dust through the dust bag 503, so that the dust is stored in the dust collector 3. When the dust in the dust collector 3 needs to be cleaned, the first drive motor 704 is started to drive the first connecting rod 705 to rotate, and the rotation of the first connecting rod 705 drives the first gear 706 to rotate, and then the first gear 706 drives the second gear 707 and the second connecting rod 708 to rotate, so that the second connecting rod 708 can drive the stirring rod 709 and the first pulley 710 to rotate. When the first pulley 710 rotates, it can drive the second pulley 712 to rotate through the belt 711, so that the second pulley 712 can drive the threaded rod 713 to rotate.By rotating the threaded rod 713, the two sets of scrapers 714 can move inward at the same time. The inward movement of the scrapers 714 can clean the dust in the dust collector 3 into the collection box 702 through the dust outlet pipe 701. The water pipe is connected to the water inlet 717, and the water pump 716 is started to transport water from the water inlet 717 into the connecting pipe 718. Water is sprayed through the nozzle 719. At the same time, the first drive motor 704 is started again, and the first connecting rod 705 and the second connecting rod 706 and the second gear 707 are driven to rotate. The stirring rod 709 on the connecting rod 708 rotates, mixing the water and dust. The mixed dust is then discharged through the water outlet 720, preventing dust from accumulating in the dust collector 3 and affecting the dust removal effect. The second connecting rod 708 drives the first pulley 710 to rotate, and the first pulley 710 drives the belt 711, which drives the second pulley 712, so that the scraper 14 can move to its original position. The above is the working principle of an asphalt concrete mixing plant with cyclic intermittent dust removal function.
