Description

Technical Field

[0001] The utility model relates to the technical field related to sanitation equipment, in particular to a suction nozzle structure of a washing and sweeping vehicle. Background Art

[0002] The surfaces of urban roads, elevated roads or highways are covered with rainwater, dust, fallen leaves, gravel and other debris. When passing vehicles are driving at high speed, splashing will occur, affecting the safety of drivers or passers-by. Therefore, the road surface needs to be cleaned. A road sweeper is a vehicle that is responsible for washing, flushing and sweeping operations in urban areas, national highways, highways and other roads. The road sweeper consists of two brush discs, a central wide suction cup, or four sweeping discs and a rear suction port.

[0003] The existing technology has the following shortcomings: most of the existing suction nozzle structures of the road sweepers are welded in one piece, the position of the suction nozzle is fixed, and the sewage, garbage, etc. are flushed to the suction nozzle opening by the side spray bars on both sides to complete the road cleaning and sweeping. However, there is a certain distance between the suction nozzles and between the side spray bars and the suction nozzles, which causes a waste of water resources and is prone to incomplete cleaning, affecting the cleanliness of the road surface. At the same time, the suction nozzle is only a simple cylindrical structure, which requires multiple sets of vacuum pumps to provide strong suction, resulting in poor energy-saving effect and prone to debris falling;

[0004] In the prior art, a "suction nozzle structure for a washing and sweeping vehicle" with a publication number of CN219547663U is provided with multiple groups of suction ports and suction main pipes to complete comprehensive washing and sweeping operations. Although the number is large, there is a distance between the suction ports, and the assistance of side spray rods is required, a large amount of water resources need to be used, resulting in a waste of water resources, and incomplete washing and sweeping may occur. At the same time, the suction nozzle is only a simple cylindrical structure, which requires a vacuum pump to provide strong suction, and the energy-saving effect is poor. Utility Model Content
