When the utility model uses, shovel board 2 scoops up the foul on ground to cambered surface 3 first, is then passing through brush roll By the foul in cambered surface 3, along cambered surface 3, brush is swept upwards under 10 bristle action, when the foul in cambered surface 3 is made in the bristle of brush roll 10 When being swept at 8 position of strip through-hole with lower brush, the suction function due to air draught chamber 4 in cambered surface 3 positioned at bar shaped to lead to It continues to move in foul sucking air draught chamber 4 at 8 position of hole and under the action of negative pressure, until being blocked by filter plate A7, by mistake Material collecting tank 12 will be fallen into downwards after the foul that filter plate A7 is blocked is cumulative, when gravity is greater than vacuum force It is interior.

With the traveling forward of car body 1, ground cylinder A14 inswept before passing through, floor surface is not swept clean at this time The surface that floating ash dust is adsorbed on cylinder A14 under electrostatic interaction is adsorbed with floating ashes then as the rotation of cylinder A14 The surface cylinder A14 of dirt is passed through at 40 position of air draught transverse tube, since the suction function of air draught chamber 4 is thus by the surface cylinder A14 position Foul at 40 position of air draught transverse tube is entered in air draught chamber 4 by air draught transverse tube 40, since the material of air draught transverse tube 40 is Metal after being grounded again by electric discharge chain 18, no longer has electricity by air draught transverse tube 40, into the floating grey dust in air draught chamber 4 Lotus, floating ash dust are continued to move to, until being blocked by filter plate A7 along air draught chamber 4 under the action of negative pressure, are blocked by filter plate A7 It will be fallen into downwards in material collecting tank 12 after floating ash dust is cumulative, when gravity is greater than vacuum force.

When foul, the floating ash dust in material collecting tank 12 are more, by unlocking the lock of material collecting tank 12 Yu car body 1, Then material collecting tank 12 is taken out, and by material collecting tank 12 foul or floating grey dust outwell after be again loaded into car body.

Filter plate A7 can be observed in passing when material collecting tank 12 is extracted out, it is right when filter plate A7 is excessively dirty Filter plate A7 is replaced.

Car body 1 continues the ground that dirt was removed before forward passing through cylinder B21, at this time the cloth of cylinder B21 and ground face contact It has been soaked by watering transverse tube 23 before material 22, contact and relative friction of the cloth 22 of wetting with ground to be bonded ground Dust also erases, and with the rotation of cylinder B21, wipes the surface of the cylinder B21 of dust by water squeezing plate 34, and pass through water squeezing The effect of plate 34 will be squeezed out by the dirty water containing dust in the cloth at 34 position of water squeezing plate and is dropped in by scouring On ground.

Finally with the traveling forward of car body 1, squeezed out by water squeezing plate 34 and drip again dirty water on the ground first with Scraping article A28 contact while so that the dirty water on ground is gathered to centre, can also be played dirty water brush due to the structure of scraping article A28 And back through scraping article A28, between scraping article A28 and scraping article B29, and continue under the action of scraping article B29 to gather to centre, And after being swept by scraping article B29, water tank 24 is sucked by suction hose 30, after dirty water passes through the filtering of filter plate B32, into water In case 24, and the wetting of the cloth 22 for the surface cylinder B21.

Due to dirty water drippage on the ground after, dust in dirty water in water can not with ground Rapid contact, even if dirty After dust and ground face contact in water, it also can not effectively be fixedly connected with ground, can still be taken away easily by water, so dirty water is dripped After on the ground, before water evaporation, secondary pollution will not be caused to ground.And due to being dropped in ground in the utility model The dirty water in face is siphoned away by de-watering apparatus at once, so more can guarantee that dirty water will not generate secondary pollution to ground.

Filter plate B32 is observed by visual windows 27, when filter plate B32 is excessively dirty, openable the cover is filtered The replacement of plate B32.
