Description

Technical Field

[0001] The present invention relates to the technical field of road cleaning, and particularly relates to a combined suction and sweeping road sweeper. Background Art

[0002] A road sweeper is a vehicle for road cleaning and sanitation; it has multiple functions such as road cleaning, road washing, and low-pressure flushing; it can be widely used for road cleaning on arterial roads, municipal areas, airport runways, urban residential areas, parks, etc.; washing and sweeping can not only clean up garbage, but also wash the road, which not only ensures the beauty of the road, maintains environmental hygiene, keeps the road in good working condition, but also reduces and prevents the occurrence of traffic accidents and further extends the service life of the road surface.

[0003] During the working process of traditional road sweepers, the inventor found that there are still some problems in the washing and sweeping process, which are specifically as follows:

[0004] 1. When traditional road sweepers clean roads with a large amount of sediment, most of the sediment can only be washed away, and thus the sediment will accumulate on the roadside. Such simple flushing cannot clean the road surface, resulting in poor cleaning and requiring multiple cleanings, which affects work efficiency.

[0005] 2. When traditional road sweepers are working, a large amount of water will be sprayed on the road surface by high-pressure water guns. After the cleaning work is completed, this water remains on the road surface, wasting a large amount of water resources and making the road surface slippery, posing a safety hazard.

[0006] In view of this, in order to improve the above technical problems, the present invention provides a combined suction and sweeping road sweeper, and its specific beneficial effects are as follows:

[0007] 1. The present invention installs an adjustable bucket at the bottom of the vehicle frame, fixedly installs a suction pipe on the bucket, and installs a motor box in the water tank. A suction motor is installed in the motor box. By the operation of the suction motor, suction is generated in the suction pipe, and the larger sediment is sucked away by the suction, and the washing and sweeping of the road surface with more sediment is realized in cooperation with the cleaning unit; the cleaning effect is effectively improved.

[0008] 2. The present invention designs the bucket into a hollow semi-cylindrical shape, which can effectively collect the water sprayed by the cleaning unit. At the same time, a polyester filter cloth and a filter screen are installed between the water tank and the second dustbin, so that the collected water mixed with mud can flow back into the water tank again after simple filtration, achieving the effect of recycling, saving water resources and reducing the safety hazard caused by excessive water accumulation on the road surface.
