Description

Dry road vacuum cleaner

Technical field

The utility model relates to the technical field of road cleaning vehicles, in particular to a dry-type road cleaning vehicle.

Background technique

Existing urban street cleaning vehicles mostly adopt rotating cleaning discs to sweep dust and rubbish off the ground, and then use wind force to inhale the ash box. The disadvantages of this kind of sweeper are that first, there will be secondary dust during work, which will affect the air quality of the city; It is convenient to work in winter in the cold northern regions of our country.

Contents of the invention

The purpose of this utility model is aimed at the deficiencies of the prior art, to provide a new type of road sweeper that does not need to clean the disc and does not need to sprinkle water during work, so as to reduce the use cost and improve the use performance.

In order to achieve the above object, the utility model adopts the following technical scheme: it includes a car chassis with a power drive and a walking system, behind the driver's cab there is also a dust-absorbing engine installed on the car chassis and a motor driven by the engine through a transmission. Fan, behind the fan, there is an ash box installed on the chassis of the car through a hinge shaft. The ash box is divided into a lower sealed ash box and an upper dust filter ash box by a partition in the middle. There is an ash box at the rear opening of the two ash boxes. The door is connected with a car cover at the front ends of the two ash boxes. There is an opening on the top surface of the dust filtering ash box, and a dust filtering device is arranged below the opening. An upwardly protruding top cover is also installed on the dust filter ash box and the car cover, and an air outlet is provided at the front part of the top cover. A dust suction pan is installed under the chassis of the car, and the upper end of the dust suction pipe installed on the dust suction pan communicates with the sealed ash box. The air pipe is communicated with the sealed ash box, and the air outlet on the upper part of the fan is communicated with the dust filter ash box through the air outlet pipe.

The dust suction pan of the utility model has a thin air chamber, an air blowing pipe communicates with the air chamber, and a plurality of air blowing nozzles are arranged below the air chamber.

Both sides of the front portion of the utility model are also hinged with telescopic dust collectors that can be expanded outwards.

Because the utility model completely adopts the airflow inhalation method to remove the dust on the road surface, there is no need for the cleaning disk to rotate and clean, and there is no secondary dust, so the air quality of the street environment will not be affected during operation; since there is no use and consumption of the cleaning disk, the use cost can be greatly reduced. The trolley can save 30,000 to 40,000 yuan per year, and is easy to use and maintain; since there is no need to sprinkle water during the work process, water resources are saved and operating costs are reduced, and it can also work normally in winter in the cold northern regions of our country.

Detailed ways

The embodiment shown in the drawings comprises an automobile chassis 1 with power drive, walking system 2 and driver's cab 3, behind the driver's cab 3 there is also an engine 4 installed on the automobile chassis 1 and driven by the engine 4 through transmission 5 The blower fan 6 of impeller 33 is housed in the inside. At the fan 6 rear, there is an ash box installed on the rear part of the automobile chassis 1 by a hinge shaft 20. The ash box is divided into two parts, the sealed ash box 19 of the bottom and the dust filter ash box 11 of the top, by the inclined flat partition plate 16 of the middle part. The oil cylinder that drives the ash box to rise and fall is installed on the chassis 1. Openings at the two ash box rear ends are provided with ash box doors 18, and ash box door opening and closing oil cylinders 17 are housed behind the dust filter ash box 11. The car outer cover 7 that engine 4 and blower fan 6 are covered therein is connected at two ash box front ends. The top surface of the dust filter ash box 11 has an opening, and a dust filter 15 is housed below the opening. Above the dust filter ash box 11 and the car cover 7, an upwardly protruding top cover 14 is also installed, and the top cover 14 front portion both sides are provided with an air outlet 8. The bottom of the automobile chassis 1 is equipped with a dust suction pan 21 close to the road surface and an oil cylinder 28 that drives the dust suction pan 21 to lift. The suction pan 21 has a thin air chamber 22 , and the suction pan 21 is symmetrically provided with two main air blowing pipe interfaces 29 , two auxiliary air blowing pipe interfaces 31 and two dust suction pipe installation adapters 30 . The inside of the housing of the blower fan 6 is provided with a fixed vane 34 that guides the airflow to its lower air outlet, and the air blowing pipe 24 connected to the lower air outlet of the blower fan communicates with the air chamber 22 through the main air blowing pipe interface 29, and through the auxiliary air blowing pipe interface 31 The auxiliary air blowing pipe 9 upper end that is communicated with air chamber 22 is communicated with the air chamber below the top cover 14, and the dust suction pipe 13 lower end passes through the dust suction pipe installation connecting pipe 30, and the upper end communicates with the sealed ash box 19. A plurality of rubber blowing nozzles 25 are housed below the air chamber 22 . On both sides of the front part of the dust collector 21, there are also hinged telescopic dust collectors 26 driven by oil cylinders that can be expanded outwards. The air blowing pipe 27 upper end is communicated with the air chamber below the top cover 14, and the rubber blowing nozzle 25 is also equipped with the telescopic suction cup 26 below.
