The water inlet of the water pump 4 is communicated with the water accumulating tank 3 through a pipeline, and the water outlet of the water pump 4 is connected with a water pipe tee 46 through a pipeline. The water pipe tee 46 is connected with a transverse water outlet pipe 41 along the length direction of the vehicle base 1, and one end of the transverse water outlet pipe 41, which is far away from the water pipe tee 46, is fixedly connected with a shower nozzle 43; the water pipe tee joint 46 is fixedly connected with a vertical water outlet pipe 42 along the height direction of the vehicle base 1, the vertical water outlet pipe 42 vertically penetrates through the vehicle base 1 and is communicated with a horizontal longitudinal water outlet pipe 45, the longitudinal water outlet pipe 45 is arranged along the width direction of the vehicle base 1, and a plurality of ground spray heads 44 are arranged on the longitudinal water outlet pipe 45 at equal intervals along the length direction of the longitudinal water outlet pipe 45. The vehicle base 1 is provided with a dust collection assembly for absorbing moisture-containing flying dust. The water pump 4 conveys water in the water collecting tank 3 to a water pipe tee 46, the water pipe tee 46 divides the water into two parts, one part of the water is sprayed into the air from the shower nozzle 43 on the transverse water outlet pipe 41, and the other part of the water is sprayed out from the ground nozzle 44 to the ground through the vertical water outlet pipe 42 and the longitudinal water outlet pipe 45 in sequence.

As shown in fig. 2, the suction assembly includes a suction pump 5, a suction duct 51, and an exhaust duct 52. The air pump 5 is arranged on the vehicle base 1, and the air pump 5 can be a vacuum pump or an electric air pump. The air suction pipe 51 is fixedly connected with an air inlet of the air suction pump 5, and the air suction pipe 51 can be arranged along the length direction of the vehicle base 1. An air suction port 512 is fixedly connected to one end, far away from the air suction pump 5, of the air suction pipe 51, a filter screen 511 is arranged on the air suction pipe 51 and close to the air suction port 512, the filter screen 511 can be a PM10 filter screen and can filter and adsorb large-particle raised dust and water drops in air, and the filter screen 511 can be detachably connected to the inner wall of the air suction pipe 51 through bolts. The exhaust pipe 52 is fixed to the exhaust port of the suction pump 5, and one end of the exhaust pipe 52 away from the suction pump 5 is inclined toward the road surface. Thus, the moisture-containing dust is filtered by the filter net 511 in the suction pipe 51 and then enters the suction pump 5, and the gas discharged from the suction pump 54 is substantially free of dust.

As shown in fig. 2 and 3, a rectangular exhaust port 523 is installed at one end of the exhaust duct 52 away from the air pump 5, a square plate 524 is fixedly connected to one end of the rectangular exhaust port 523 away from the air pump 5, a plurality of air outlet holes 5241 are formed in the square plate 5 along the length direction of the square plate, and the rectangular exhaust port 523 and the square plate 5 are arranged to increase the area of air exhaust. A heating wire 521 is installed on the inner wall of the exhaust duct 52 near the rectangular exhaust port 523, and the heating wire 521 is electrically connected to an external switch. In order to prevent water in the dust-containing gas from falling onto the heating wire 521, a water absorption block 522 is installed inside the exhaust duct 52. The water absorption block 522 is made of a water absorption material, such as silica gel, so that water in the dust-containing gas can be sufficiently absorbed. In order to prevent the water absorption block 522 from blocking the air flow in the exhaust duct 52, the water absorption block 522 is provided with a plurality of exhaust holes 5221, so that the contact area between the air and the water absorption block 522 is increased when the air flows through the exhaust holes 5221, and the water absorption effect of the water absorption block 522 is more excellent. The gas flowing out from the suction pump 5 passes through the water absorption block 522 to be dehydrated, the dehydrated gas passes through the exhaust hole 5221 to reach the heating wire 521, and the heating wire 521 heats the gas, so that the gas flowing out from the exhaust pipe 52 has a high temperature, and the high-temperature gas can dry water on the road surface. This increases the drying rate of the ground and reduces the possibility of a pedestrian slipping or a vehicle slipping due to the water spray causing the road surface to be muddy.

As shown in fig. 1, a blade 6, a roller 7, and a baffle plate 8 are mounted in this order below the vehicle body 1 between the ground shower head 44 and the rectangular exhaust port 523 of the exhaust duct 52. The shovel plate 6 is vertically fixed in vehicle base 1 bottom, and the one end that shovel plate 6 kept away from vehicle base 1 is arc end and extends towards ground shower nozzle 44, and the bottom of shovel plate 6 is apart from ground 2 cm. The shovel plate 6 can shovel off larger stones on the road surface, so that the risk that the rollers 7 are damaged by the larger stones can be reduced. The vehicle base 1 is fixedly connected with two parallel support plates along the width direction, the rotating roller 7 is rotatably connected with the support plates, a plurality of brushes 71 are distributed on the rotating roller 7 at equal intervals along the circumferential direction of the rotating roller, and the brushes 71 are in contact with the road surface. When the vehicle base 1 moves, the roller 7 moves relative to the ground to generate friction force, and the friction force drives the roller 7 to rotate, so that the roller 7 drives the brush 71 to scrub the road surface. 8 one ends of baffle plate rigid couplings in vehicle base 1 bottom, 8 other ends of baffle plate are apart from road surface 2 centimetres, and the bottom of baffle plate 8 is the arc, and the arc end of baffle plate 8 sets up towards rectangle gas vent 523. The baffle 8 is sleeved with a mop cloth 81, one end of the mop cloth 81 is contacted with the road surface, and the other end of the mop cloth 81 is fixedly connected with the baffle 8, so that the road surface brushed by the brush 71 can be cleaned by the mop cloth 81.

This kind of dust fall watering lorry for municipal construction's theory of operation as follows:

when the vehicle base 1 moves forwards, the water pump 4 and the air pump 5 are started, the water pump 4 conveys water in the water accumulating tank 3 to the water pipe tee 46, the water pipe tee 46 divides the water into two parts, one part of the water is sprayed out from the shower nozzle 43 on the transverse water outlet pipe 41 to the air, and the other part of the water is sprayed out from the ground nozzle 44 to the ground through the vertical water outlet pipe 42 and the longitudinal water outlet pipe 45 in sequence.

The water sprayed from the ground spray head 44 washes the ground firstly, then the roller 7 drives the brush 71 to wash the ground, and finally the mop 81 cleans the ground once again, so that the road surface can be cleaned cleanly by the three steps, and the possibility of dust formation after the road surface is dry is greatly reduced.

The water sprayed from the shower nozzle 43 is combined with the dust in the air, so that the air dust falls down, the suction pump 5 forms a suction force, and the dust is sucked into the suction pipe 51. The dust sucked into the suction duct 51 is first filtered by the filter net 511, and the gas filtered by the filter net 511 flows through the suction pump 5 to the exhaust duct 52. The gas reaching the exhaust pipe 52 is dehydrated through the water absorption block 522, the gas dehydrated through the water absorption block 522 reaches the heating wire 521, and the heating wire 521 heats the gas to a higher temperature, so that the gas with the higher temperature can dry the water on the road surface, the drying process of the road surface is accelerated, and the possibility that pedestrians slip or vehicles slip due to a muddy road surface is reduced.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
