Description
Technical Field
[0001] The invention belongs to the technical field of cleaning vehicles, and particularly relates to a high-speed air-washing cleaning vehicle. Background Art
[0002] There are haze and dust pollution; with the increase in the mileage of roads and the substantial increase in vehicles, traffic dust pollution and dust are the main sources; with the rapid development of transportation, roads, as an important part of the modern transportation network, their cleaning and maintenance work has become increasingly important. In the past, after watering the dirt road, the dust merged with the ground; now, on cement and asphalt roads, the dust cannot merge with the ground; currently, the main source of road dust is that when a vehicle passes by, the tires and chassis bring soil onto the road, and after repeated rolling by vehicles, fine dust rises with the hot air flow to form air pollution, and larger particles and foreign objects splash to the roadside; when watering for dust reduction, on the watered road surface, the water splashes onto the tires and chassis of the driving vehicles, and the dirt on the vehicle beams is washed and falls onto the road surface, forming secondary pollution. Currently, among the existing cleaning vehicles, there are mainly pure suction type, sweeping and suction type, and blowing and suction type. The suction ports of the existing cleaning vehicles are all circular suction ports, and the center position of the suction port is far from the edge of the suction port, with a small flow rate. The negative pressure of the suction port cannot completely suck up the particulate garbage. This defect is more obvious when the cleaning vehicle runs at a high speed, resulting in slow cleaning speed, low efficiency, time-consuming and energy-consuming, and poor cleaning effect. For the sweeping brush type cleaning vehicle, some of the dust and water from watering for dust reduction fall to the ground, and the dust cannot be completely collected. The gravity dust removal in the dust removal bin requires a certain amount of water, about 600 kilograms of water per kilometer. The uncleaned water splashes onto the passing vehicles, soiling the vehicles, and the collected sewage is discharged into the sewer, increasing the burden of sewage treatment. The pure suction type cleaning vehicle cannot collect the dust in the potholes and gaps by air flow. Summary of the Invention

[0014] The technical solution of the present invention has the following advantages:
[0015] 1. The front elastic air nozzle is connected to the air box through a rubber bellows at a certain angle. The pressure generated by the air flow pushes the air nozzle to the positioning position. The high-speed air flow blows towards the ground, blowing the garbage towards the suction port. Through the negative pressure generated by the suction port, the garbage is collected faster through the strong convection on the ground of the suction port. The missed dust is collected again through the rear suction port and enters the negative pressure chamber, where it undergoes pulse dust removal in the dust removal chamber. The air flow returns to the air inlet of the high-pressure blower, thus forming a closed air flow wind tunnel phenomenon and realizing the recycling of the operating air flow. The strong convection high-speed suction port on the ground can better collect garbage, thereby improving the suction force and cleaning effect. Under the same vehicle type and the same road surface environment, the efficiency of this cleaning vehicle can be increased by three to four times. The suction air volume of the suction port is greater than 30-40% of the blowing air volume of all the blowing nozzles. The excess air volume is discharged through the exhaust valve of the air box.
[0016] 2. The sand flows out through the middle of the second front air nozzle and the second rear air nozzle. The high-pressure air blown out by the second front air nozzle and the second rear air nozzle makes the sand hit the ground at high speed. Through the high-speed air flow at the blowing port and the suction force of the front suction port, a high-speed air flow is formed in the sandblasting disc to realize sandblasting for cleaning the ground attachments. The multiple guide plates reflect multiple times, enabling the sand to rub against the ground multiple times. The sand sprayed onto the ground is collected into the negative pressure chamber through the sand suction port and the steel hose, and falls into the sand box through the suction pipe pressure reduction device and the sand falling device, realizing the recycling of the sandblasting sand, which is energy-saving and environmentally friendly. The sand suction air volume of the sand suction port is greater than 35-45% of the blowing air volume of all the blowing nozzles. The excess air volume is discharged through the exhaust valve of the air box.

[0035] The present invention provides a high-speed air-washing cleaning vehicle, as Figure 1-9 shown, comprising: a vehicle chassis 1, a sub-engine 2 and a high-pressure blower 3 are arranged at the front of the vehicle chassis 1, a negative pressure bin 4 is arranged at the tail of the vehicle chassis 1, dust removal bins 5 are arranged on both sides of the negative pressure bin 4, a pulse dust collector and filter cartridges are arranged in the dust removal bins 5, the output end of the sub-engine 2 is connected to the input end of the high-pressure blower 3, the output end of the sub-engine 2 is connected to a first pulley, the input end of the high-pressure blower 3 is connected to a second pulley, the first pulley and the second pulley are connected by a belt, the air inlet of the high-pressure blower 3 is communicated with the air outlet of the dust removal bin 5, a combined air-washing suction cup 6 is arranged below the vehicle chassis 1, a suction port 7 is arranged on the combined air-washing suction cup 6, the lower end of the suction port 7 is composed of a front suction port 8 and a rear suction port 9, a plurality of rows of elastic air nozzles 10 are arranged in front of the front suction port 8, a shovel deflector 11 is arranged between the front suction port 8 and the rear suction port 9, the shovel deflector 11 is triangular, a first rear air nozzle 12 is arranged at the rear side of the shovel deflector 11, the elastic air nozzles 10 and the first rear air nozzle 12 are inclined towards each other and are both communicated with an air box 13, the air box 13 is communicated with an air box 14 at the air outlet of the high-pressure blower 3, the air box 13 is located in the combined air-washing suction cup 6, the air box 13 is connected to the combined air-washing suction cup 6, a plurality of air distribution valves and exhaust valves are arranged on the air box, the air distribution valves are used to adjust the air volume of each air outlet, the exhaust valve is communicated with a muffler and is used to discharge a part of the air volume when the air volume is too large, and after eliminating the noise, it is discharged into the external air, and the suction port 7 is communicated with the air inlet of the negative pressure bin 4. The angle between the first rear air nozzle 12 and the ground is 30-35°, the distance from the ground is 7-15 mm, and the distance between the rear suction port 9 and the ground is 5-15 mm. The shovel deflector 11 is made of high-strength material and has a certain angle with the ground. When subjected to a strong impact, the suction port is instantly lifted, playing a protective role for the suction port and the first rear air nozzle.
[0036] Working principle and beneficial technical effects of the above technical solution: The high-pressure air blown out by the high-pressure fan 3 is adjusted in air volume through the air distribution valve and blown into the elastic air nozzle 10 and the first rear air nozzle 12. The high-speed air flow from the front elastic air nozzle 10 blows towards the ground, blowing the garbage towards the front suction port 8. Through the negative pressure generated by the suction port 7, the strong ground convection through the front suction port 8 can collect the garbage faster. The missed dust is collected again through the rear suction port 9 and enters the negative pressure bin 4. The volume of the negative pressure bin relative to the suction pipe increases and the flow rate decreases, and the garbage falls into the negative pressure bin. The dust passes through the dust removal bin 5 for pulse dust removal, and the air flow returns to the air inlet of the high-pressure fan 3, thus forming a closed air flow wind tunnel phenomenon and realizing the recycling of the working air flow. The strong ground convection high-speed suction port can better collect garbage, thereby improving the suction force and cleaning effect. Under the same vehicle type and the same road surface environment, the efficiency of this cleaning vehicle can be increased by three to four times.
[0037] In one embodiment, a water tank is provided in front of the high-pressure fan 3 on the vehicle chassis 1, and a nozzle is provided on the tail door of the negative pressure bin 4.

One end of a tension spring 17 is hinged to the combined air and water suction cup 6, and the other end of the tension spring 17 is hinged to the swing rod 16. When the two telescopic air and water suction cups 15 encounter the roadside, the telescopic air and water suction cups 15 are squeezed and will retract inward to prevent the suction cups from being damaged by impact. When the telescopic air and water suction cups 15 affect the driving vehicle, they are retracted into the vehicle and fixed pins are inserted. Rollers 18 are respectively provided at the front end and the front and rear sides of the combined air and water suction cup 6. The vehicle pulls the combined air and water suction cup 6 to move through a pull rod, and at the same time drives the telescopic air and water suction cup 15 to move through the swing rod. When the combined air and water suction cup is not needed, the hydraulic rod first retracts the telescopic air and water suction cup 15 through the steel wire rope on the pull rod, and then retracts the entire suction cup upward.

An outer air nozzle 24 is provided at the lower end of the wind hood elastic plate 23, and the angle can be adjusted to blow the garbage on the roadside in the reverse direction. A negative pressure air duct is provided at the lower end of the outer air nozzle. When there is a foreign object in front of the suction cup or the roadside is uneven, the front guiding protection plate 19 makes the suction cup contract to play a protective role; when there is a foreign object on the ground in front of the suction cup or the road surface is uneven, the front protection wheel 20 makes the suction cup lift or contract to play a protective role; when the roadside has unevenness or a notch, the side protection wheels 21 and the side protection elastic plates 22 ensure that the suction cup keeps a certain distance from the roadside and play a protective role.

[0043] Working principle and beneficial technical effects of the above technical solution: When there are other attachments on the road surface, the high-pressure air of the high-pressure blower 3 adjusts the air volume through the air distribution valve on the air box 14 and enters the air inlet steel wire hose 47, and at the same time is sent to the front air nozzle 44 and the second rear air nozzle 45. At this time, the sand leakage steel wire hose 49 is opened through the electric butterfly valve, and the sand flows out through the sand flow nozzle 46 between the front air nozzle 44 and the second rear air nozzle 45. The high-pressure air blown out by the front air nozzle 44 and the second rear air nozzle 45 makes the sand hit the ground at high speed. Through the high-speed air flow of the front air nozzle 44 and the second rear air nozzle 45 and the suction force of the sand suction port 52, a high-speed air flow is formed in the sand blasting suction cup 43 to realize sand blasting and cleaning of the ground attachments.
