Cleaning suction nozzle and cleaning vehicle

Abstract

The invention discloses a cleaning suction nozzle which comprises a suction nozzle main body capable of moving along an object to be cleaned. The suction nozzle main body is provided with an air inlet, an air gathering area surrounding the air inlet is formed on the lower side of the suction nozzle main body, an opening is arranged at the front end of the air gathering area, air with garbage passes through the opening, air surrounding the suction nozzle can enter the air gathering area from the periphery of the suction nozzle and then enters the air inlet, a front baffle is arranged at the front of the opening, and a groove which is recessed forwards is formed on a first side surface, which faces the air gathering area, of the front baffle. The invention further discloses a cleaning vehicle using the cleaning suction nozzle. Because the air gathering area is formed on the lower side of the suction nozzle main body, the front baffle is arranged at the front end of the air gathering area, and the groove which is recessed forwards is formed on the first side surface, which is opposite to the air gathering area, of the front baffle, air vortex can be strengthened, suction force of the air inlet is increased, and the cleaning efficiency of the cleaning vehicle using the suction nozzle is high.

Description

technical field [0001] The invention relates to the field of cleaning garbage by using vacuum negative pressure, in particular to a cleaning nozzle and a cleaning vehicle using the nozzle. Background technique [0002] In the field of using vacuum negative pressure to suck garbage, the cleaning nozzle plays an important role in garbage suction. Under the action of vacuum negative pressure, the gas mixed with garbage can enter the designated garbage storage area through the suction nozzle. For example, in the field of cleaning vehicles, especially in road sweeping vehicles, under the suction of the fan, garbage can enter the dustbin of the road sweeping vehicle through the suction nozzle together with the air, thereby achieving the purpose of road cleaning. Therefore, the design form of the suction nozzle also directly affects its own suction rate of garbage and the cleaning ability of the cleaning vehicle using the suction nozzle on the road surface. [0003] At present, in...

AI Technical Summary

Problems solved by technology

[0003] At present, in cleaning vehicles such as road sweepers equipped with cleaning nozzles, since the cleaning vehicles themselves have a fixed upper limit for the cleaning rate of road garbage, when the amount of road garbage and the thickness of the garbage layer exceed the existing cleaning capacity of the road sweeper , there will be garbage residue on the road after the cleaning operation, resulting in poor cleaning effect

The method of increasing the power of suction sources such as fans not only wastes energy, but also causes impacts on related components and affects their service life
