Purely sweeping type road sweeper

Abstract

The invention belongs to the technical field of an environmental sanitation vehicle, in particular to a pure-sweeping typed cleaning vehicle. The cleaning vehicle comprises an automobile chassis, a middle sweeping device assembly, a garbage conveyer assembly, a garbage collecting box and a hydraulic system. The rear suspension position of the automobile chassis is fixedly provided with the middle sweeping device assembly; wherein, a roller brush is arranged on the shell of the middle sweeping device; the roller brush is connected with the hydraulic motor of the middle sweeping device by a chain wheel pair; the front part of the roller brush is provided with a feeding dustpan hole; the front part of the feeding dustpan hole is provided with a garbage feeding hole; and a lifting hydraulic cylinder of the middle sweeping device is arranged between the shell of the middle sweeping device and the automobile chassis. The pure-sweeping typed cleaning vehicle integrates collecting, sweeping and dust-pressing into a whole, has simple structure, little malfunction, is not restricted by reasons and provided with a spraying dust-pressing device, thus avoiding the secondary pollution due to dust flying during the operation process.

Description

Technical field: [0001] The invention belongs to the technical field of sanitation vehicles, in particular to a pure sweeping road sweeper. Background technique: [0002] At present, the road sweeping vehicles used in China use the combination of suction and sweeping to complete the cleaning of the road surface. The defects of this type of sweeping vehicles are: 1. Due to the large power consumption of the dust suction fan, this type of vehicle generally uses two The engines work at the same time to complete the cleaning operation, the chassis engine is used for walking, and the auxiliary engine is used to provide power for the cleaning system, which not only consumes a lot of fuel, but also costs a lot, and also has a large amount of exhaust gas emissions; moreover, the noise generated by the two engines is large, It will cause noise pollution to the surrounding environment, and since the main and auxiliary engines are respectively located below and behind the cab, the work...

Problems solved by technology

[0002] At present, the road sweeping vehicles used in China use the combination of suction and sweeping to complete the cleaning of the road surface. The defects of this type of sweeping vehicles are: 1. Due to the large power consumption of the dust suction fan, this type of vehicle generally uses two The engines work at the same time to complete the cleaning operation, the chassis engine is used for walking, and the auxiliary engine is used to provide power for the cleaning system, which not only consumes a lot of fuel, but also costs a lot, and also has a large amount of exhaust gas emissions; moreover, the noise generated by the two engines is large, It will cause noise pollution to the surrounding environment, and since the main and auxiliary engines are respectively located below and behind the cab, the working noise generated will also have a great impact on the driver. Even if the cab is sealed and air-conditioning and audio are installed, It can only alleviate the noise, but not the root cause

2. The dust removal system of the suction-sweeping road sweeper generally adopts circulating water to depressurize dust removal. The air pressure discharged from the dust removal system of the road sweeper is relatively high, and the dust removal effect of the water is good under clean conditions, but with the increase of water pollutants The dust removal effect is reduced, and the air discharged from the dustbin is likely to cause secondary pollution. At the same time, the dust removal circulating water needs to be replaced regularly, which limits the operating radius of the road sweeper and is not conducive to high-frequency long-distance operation.

3. The temperature in northern my country is low in winter, and the garbage has been frozen on the ground in winter. The suction sweeping road sweeper has limited suction and cannot collect it, and the circulating water pipeline is very easy to freeze, and even the pipeline is cracked. Restricted winter operations
