[0042] In the process of the sweeper slowly driving along the curbstone, the edge roller 501 rolls along the curbstone, the power rod 506 rotating synchronously with the edge roller 501 drives the second transmission wheel 507 to continuously rotate, and the transmission belt 508 and the first transmission wheel 505 jointly drive the synchronous rotation of the transmission rod 502, so that the continuous rotation of the reciprocating screw rod 106 is driven by the rolling of the edge roller 501, the up-down reciprocating motion of the lifting drive assembly 2 is realized by the continuous rotation of the reciprocating screw rod 106, the synchronous up-down motion of the support pipe 406 is driven by the second lifting drive rod 203, the synchronous rotation of the transmission pipe 403 is driven by the helical fitting 405 moving synchronously with the support pipe 406, and the rotation of the multi-hole trapping box 402 is realized, through the relative motion between the multi-hole trapping box 402 and the cavity partition plate 303, the light impurities trapped on the surface of the multi-hole trapping box 402 can be scraped off, and the scraped light impurities are accumulated in the impurity falling box 301, when the part of the multi-hole trapping box 402 on which the light impurities are scraped off rotates to the cavity corresponding to the second flow guide pipe 306, the airflow passing through the multi-hole trapping box 402 can realize backwashing of the part of the filter hole structure, so that the good trapping and ventilation performance of the entire multi-hole trapping box 402 can be maintained, and the long-term stable work of the multi-hole trapping box 402 can be realized, when the cleaning work is completed or the set cleaning time is reached, the light impurities in the impurity falling box 301 can be cleaned by moving the annular sealing plate 6 to open the impurity cleaning port 307, and the cleaning of the gravel in the gravity separation box 102 can be realized by opening the sealing door 7 on the gravity separation box 102.
