The output shaft 6 rotates through the transmission belt 92 to drive the driven shaft 91 to rotate. The driven shaft 91 rotates and drives the cleaning fan 93 to rotate to blow away the waste generated during the work. The waste is blocked by the arc baffle 94 and enters the interior of the collection bin 96 through the collection port 95. After the work is completed, if it rains and the interior of the collection bin 96 is cleaned, pull the handle 98 to drive the bin door 97 to flip out of the obstruction of the collection bin 96, so that the staff can operate conveniently.
