[0018] (Three) beneficial effects

[0019] Compared with the prior art, the beneficial effects of the present application are as follows:

[0020] The present application is provided with an atomizing nozzle, a sponge, an L-shaped toothed plate, an arc-shaped brush plate, an inclined pipe, an arc-shaped clamping block and a filter plate, which effectively start the motor to drive the belt pulley and the rotating shaft to rotate when the roadbed is paved with asphalt, and the sponge rotates at the same time. Then the worker starts the water pump to pump the water in the water tank to the water delivery pipe and finally to the inside of the atomizing nozzle for spraying and wetting the surface of the rotating sponge. The worker pushes the handle to drive the base and the bottom wheels to move on the surface of the roadbed, and the dust on the surface of the roadbed is adsorbed on the surface of the sponge, effectively reducing the amount of dust that is inhaled by the workers and pedestrians during the cleaning process of the road surface dust by the brush body. During the process of rotating the sponge to adsorb dust, the inclined pipe is driven to rotate by the rotating rod, and the arc-shaped clamping block connected to the inner wall of the inclined groove will drive the semicircular rod to swing left and right on the outer surface of the circular shaft according to the shape of the inclined groove. When the semicircular rod swings back and forth, it will push the arc-shaped brush plate to swing left and right on the outer surface of the circular shaft, and the brush body will clean the rotating sponge surface during the swinging process of the arc-shaped brush plate. At the same time, the sponge will be squeezed by the L-shaped toothed plate after the brush body is cleaned, and the surface water will be squeezed out at the same time, and the surface dust will also flow into the water storage chamber of the shell through the tooth grooves on the surface of the arc-shaped brush plate, effectively preventing the sponge from being unable to be used after cleaning the dust on the surface of the roadbed for a certain distance, and effectively ensuring the recycling of the sponge.

[0021] In the initial stage of the water flow into the filter plate, the sponge surface sewage flows to the bottom of the water storage chamber on one side of the shell, and the water flow decreases slowly and floats out of the water surface, and the larger particles in the water are filtered on the surface during the floating process. After the roadbed cleaning is completed, the sewage in the water storage chamber on one side of the shell is discharged by the side pipe cover of the water outlet pipe. In the process of discharging, the sewage is filtered by the semi-permeable membrane to adhere the particles in the water storage chamber. The filter plate is lowered with the particles adhering to the surface of the filter plate, and finally the staff pulls the strip to drive the plug strip to open the water storage chamber and pull out the filter plate to wash the surface clean. The dry and wet separation of sewage effectively reduces the long-term adhesion of particles in the water storage chamber to form dirt which is difficult to clean in the later period.

[0036] With the above scheme: the outer surface of the sponge 18 is oval-shaped to better utilize the self-deformation material to clean and absorb dust in the pits and bumps on the base surface again, so that the pits and bumps are also clean. One side of the brush body 32 is movably connected with the sponge 18 and the inclined L-shaped tooth plate 22, one side of the inclined L-shaped tooth plate 22 is inclined and tightly attached to the sponge 18, and tooth grooves 221 are opened in the one side of the inclined L-shaped tooth plate 22 at equal intervals. This is to make the sponge 18 surface rotate and absorb dust during the process, which will drive the inclined pipe 29 to rotate through the rotating rod 19, and at the same time make the arc-shaped clamping block 26 located in the inner wall of the inclined groove 291 drive the semicircular rod 28 to swing left and right on the outer surface of the circular shaft 30. When the semicircular rod 28 swings back and forth, it will push the arc-shaped brush plate 24 to swing left and right on the outer surface of the circular shaft 30. In the process of swinging the arc-shaped brush plate 24, the brush body 32 will swing to clean the rotating sponge 18 surface. At the same time, the sponge 18 will be squeezed by the inclined L-shaped tooth plate 22 after cleaning to squeeze out the water on the surface and at the same time the dust on the surface will flow into the water storage chamber of the housing 2 through the tooth grooves 221 on the surface of the arc-shaped brush plate 24. This effectively prevents the sponge 18 from being unable to use after cleaning the dust on the base surface for a distance, and effectively ensures the recycling of the sponge 18. After the sponge 18 surface stains and water are hung in the water storage tank through the inclined L-shaped tooth plate 22, the sponge 18 surface will be scraped again through the inclined scraper 25 to further clean the sponge 18 surface.

[0037] The working principle and use process of the present application: when using the base surface cleaning device in the asphalt cover construction, first start the motor 3 to work through the output shaft to drive the belt pulley 9 to rotate, at the same time, the rotating shaft 7 will rotate, and the sponge 18 will rotate at the same time. Then the worker starts the water pump 11 to pump the water in the water tank 12 to the water inlet pipe 15 through the water suction pipe 33, and finally to the inside of the atomizing nozzle 16, which is sprayed through atomization and the surface of the rotating sponge 18 to be wetted. The worker pushes the handle 10 to drive the base 1 and the bottom wheels to move on the roadbed surface, and the dust on the roadbed surface is adsorbed on the surface of the sponge 18, effectively reducing the amount of dust raised during the road surface dust cleaning process by the brush body, which is inhaled by the workers and pedestrians. In the process of pushing the base 1 forward, the worker encounters the uneven pits on the base surface, which will be cleaned out by the soft brush 14 at the bottom of the shell 2, and the dust on the surface of the sponge 18 will be adsorbed to ensure the cleanliness of the base surface. When the sponge 18 rotates and adsorbs dust, the rotating rod 19 will drive the inclined pipe 29 to rotate, which will make the arc-shaped block 26 clamped in the inclined groove 291 rotate along the shape of the inclined groove 291, and the semicircular rod 28 will swing left and right on the outer surface of the circular shaft 30. When the semicircular rod 28 swings back and forth, it will push the arc-shaped brush plate 24 to swing left and right on the outer surface of the circular shaft 30, and in the process of swinging the arc-shaped brush plate 24, the brush body 32 will swing to clean the surface of the rotating sponge 18. At the same time, the sponge 18 will be squeezed by the inclined L-shaped tooth plate 22 after being cleaned by the brush body 32, and the water on the surface will be squeezed out at the same time, and the dust on the surface will flow into the water storage chamber of the shell 2 through the tooth groove 221 on the surface of the arc-shaped brush plate 24, effectively preventing the sponge 18 from being unable to use after cleaning the base surface dust for a period of time, and effectively ensuring the recycling of the sponge 18. After the sponge 18 is squeezed by the inclined L-shaped tooth plate 22, the surface stains and water will be hung in the water storage tank, and then the sponge 18 will be scraped again by the inclined scraper 25 to further clean the surface of the sponge 18;

[0038] When the sponge 18 surface sewage flows into the water storage chamber on one side of the shell 2, the filter plate 21 at the bottom of the water inlet pipe 13 will slowly float out of the water surface in the initial stage of water flow reduction, and in the process of floating, the larger particles and impurities in the water will be filtered on the surface. Finally, after the roadbed is cleaned, the pipe cover 131 on one side of the water outlet pipe 13 is used to discharge the sewage in the water storage chamber on one side of the shell 2. In the process of discharging, the sewage will be filtered by the semi-permeable membrane 23 to deposit the particles in the water storage chamber. The filter plate 21 will descend with the water flow, and the particles will deposit on the surface of the filter plate 21. Finally, the worker pulls the strip plate 5 to drive the plug strip 20 to open the water storage chamber, pulls out the filter plate 21, and cleans the surface, effectively separating the sewage and reducing the deposition of particles in the water storage chamber, which will form dirt and be difficult to clean in the later period.
