Thereby cleaning the sidewalk.
When the application cleans the sidewalk, the vehicle body 1 moves forwards, in addition, the spray pipe A13 sprays liquid on the sidewalk pavement in front of the vehicle body 1, meanwhile, the driving motor A31 drives the front side of the collecting and sweeping disc 12 to rotate from the outer side of the vehicle body to the middle part of the vehicle body 1, the driving motor C drives the bottom of the feeding brush roller 19 to rotate from front to back, the driving motor B32 drives the crushing rollers 20 to mutually mesh and simultaneously rotate to one side of the feeding groove 17, the exhaust fan 8 is started, the air in the dirt separation groove 7 is pumped out of the cleaning cabin 3, and at the moment, the piston rod of the air cylinder 34 extends out of the air cylinder 34 to the maximum travel position, so that the swinging plate 33 swings to be matched and sealed with the vent hole. Due to the air suction effect of the air suction fan 8, negative pressure is formed above the liquid level in the dirt separation tank 7 and above the liquid level in the filter tank 36, so that the liquid level in the filter tank 36 rises and the liquid level in the feed tank 17 falls; when the liquid level in the filter tank 36 rises to be level with the partition plate B35, if the liquid level in the feed tank 17 is still higher than the bottom edge of the partition plate A16, the liquid level in the filter tank 36 and the liquid level in the dirt separation tank 7 can continuously rise under the action of the exhaust fan 8 until the liquid level in the feed tank 17 falls to be just lower than the bottom edge of the partition plate A16; at this time, due to the continuous operation of the exhaust fan 8, air in the feed tank 17 is pumped into the filter tank 36 through the lower part of the bottom edge of the partition plate A16, upwards passes through the cleaning liquid in the filter tank 36, enters the cavity above the liquid level of the filter tank 36, and is finally pumped out by the exhaust fan 8; The dirt wetted by the cleaning liquid sprayed out of the liquid spraying pipe A13 is gathered from the two sides of the vehicle body 1 to the middle part of the gathering sweep plate 12, and then is fed into the flaring feed hopper 18 by the feeding brush roller 19, and the external air entering the flaring feed hopper 18 is pumped into the pumping pipe 9 and the feeding groove 17 together with the dirt and the cleaning liquid in sequence; the feeding brush roller 19 continuously rotates upwards after feeding dirt to the flaring feed hopper 18 and contacts with the scraping comb 21 arranged at the inner top of the flaring feed hopper 18, so that the dirt remained on the bristles of the feeding brush roller 19 is scraped into the flaring feed hopper 18 by the scraping comb 21 and is pumped into the pumping pipe 9 and the feeding groove 17; the dirt passes through the bite of the particle roller 20 before entering the feed chute 17 from the suction tube 9; the dirt which is meshed with the crushed aggregates by the crushed aggregate roller 20 enters the primary filter tank frame 22 in the feed tank 17 along the inclined downward direction and then falls off under the dual actions of gravity and air flow, part of the dirt floats on the surface of the liquid surface in the feed tank 17, and the rest of the dirt is suspended in the cleaning liquid in the feed tank 17 or is sunk into the bottom of the cleaning liquid in the feed tank 17; the larger dirt is blocked by the primary filter frame 22 and a portion of the smaller dirt passes through the primary filter frame 22 with the cleaning liquid and enters the bottom of the filter tank 36; part of the dirt entering the filter tank 36 is blocked by the horizontal filter screen 37; Part of the dirt entering the filter tank 36 passes through the horizontal filter screen 37 upwards; a part of dirt passing upwards through the horizontal filter screen 37 is blocked by the filter net bag 38, and a part of particle dust passing upwards through the horizontal filter screen 37 also enters the filter net bag 38; most of the particle dust entering the filter net bag 38 is suspended in the cleaning liquid in the filter tank 36, and a small part of the particle dust entering the filter net bag 38 enters the cleaning liquid in the dirt separation tank 7 outside the filter tank 36 along with the flow of the cleaning liquid and is deposited; dirt in the cleaning liquid of the feed chute 17 gradually precipitates to the chute bottom B23 of the feed chute 17, and gradually falls and is collected in the dirt collecting cavity 26 after passing through the convex rod 25 at the discharge hole along the chute bottom B23; After the dirt collecting cavity 26 is fully collected, the dirt is directly deposited and accumulated on the bottom B23 of the tank; most of the dirt entering the filter tank 36 will also settle at the tank bottom C and drop into the tank bottom B23 of the feed tank 17 after passing through the primary filter tank frame 22 again along the tank bottom C; in the process that the dirt falls into the feed chute 17, the liquid suction pump 29 pumps out the cleaning liquid in the dirt collecting cavity 26 and conveys the cleaning liquid to the liquid spraying pipe B28 through the liquid outlet pipe 30 for spraying; so that the dirt remained on the side wall of the primary filter tank frame 22 is washed downwards under the action of the cleaning liquid sprayed by the liquid spraying pipe B28, and then the dirt falls downwards to be contacted with the cleaning liquid of the feeding tank 17; When the cleaning liquid in the water tank 14 is not much, the valve of the bypass pipe B41 is opened, so that the cleaning liquid in the dirt separation tank 7 outside the filter tank 36 is conveyed into the water tank 14 through the liquid discharge pipe 42, and the vehicle body 1 can be ensured to continuously spray the cleaning liquid on the sidewalk.
When one section of sidewalk is cleaned, the vehicle body 1 leaves the sidewalk and runs towards the other section of sidewalk, at the moment, the piston rod of the cylinder 34 returns to the maximum travel position of the cylinder 34, so that the swinging plate 33 swings to be separated from the vent hole, and at the moment, the air in the dirty separating tank 7 is directly communicated with the outside air through the pumping pipe 9, so that the air pressure above the filtering tank 36 is equal to the air pressure above the feeding tank 17, the liquid level in the feeding tank 17 is increased, the liquid level in the filtering tank 36 is decreased, and the liquid level in the feeding tank 17 is equal to the liquid level in the filtering tank 36; during the liquid level in the filter tank 36 and the liquid level in the feed tank 1 rise, the cleaning liquid in the filter tank 36 flows downwards and reversely flows into the feed tank 17, and the cleaning liquid in the feed tank 17 flows upwards, so that the meshes of the filter net bag 38, the meshes of the horizontal filter net 37 and the meshes of the primary filter tank frame 22 can be reversely flushed; avoiding dirt adhering to each mesh to influence the flow of the cleaning liquid; by repeatedly retracting and extending the telescopic rod from the cylinder 34 during the period, the flowing direction of the cleaning liquid in the feeding groove 17 and the filtering groove 36 can flow forward and backward for a plurality of times, the ventilation effect of each mesh is ensured, the effect of sucking away the ground dirt by the negative pressure is ensured, and the cleaning effect is finally ensured; when the vehicle body 1 again requires the cleaning of the sidewalk, the above-described cleaning process is repeated.
After the final cleaning is finished, the liquid spraying pipe A13 stops spraying liquid to the pavement of the pavement, the driving motor A31 stops driving the collecting and sweeping disc 12 to rotate, the driving motor C stops driving the feeding brush roller 19 to rotate, the driving motor B32 stops driving the crushing roller 20 to rotate, and the exhaust fan 8 is closed; then the sealing cover at the top of the cleaning cabin 3 is opened, the primary filter tank frame 22 and the filter net bag 38 are respectively taken out upwards from the feed tank 17 and the filter tank 36, and dirt in the primary filter tank frame 22 and the filter net bag 38 is removed; then the bottom cover 27 at the bottom of the vehicle body 1 is opened, and the residual cleaning liquid and dirt in the dirt collecting cavity 26, the feeding groove 17 and the filtering groove 36 are discharged downwards; the valve of the drain pipe 41 is opened to drain both the cleaning liquid and the dirt remaining in the dirt separation tank 7.
