Abstract

The invention relates to a suction nozzle, a pulse gas path control system comprising the same and a sweeping car comprising the same. The suction nozzle comprises a suction nozzle body, wherein the suction nozzle also comprises a pulse jet device which is arranged on the suction nozzle body, and the pulse jet device is used for jetting a pulse gas flow along the suction-in direction of the suction nozzle body. The pulse gas path control system comprises the suction nozzle, an induction unit used for monitoring the distribution of waste on the surface of a working road, and a control platform used for controlling the on/off of the pulse jet device of the suction nozzle according to the monitoring information fed from the induction unit. According to the technical scheme of the invention, the pulse jet device can jet a pulse gas flow along the suction-in direction of the suction nozzle body, so that a local high negative pressure region is formed at the periphery of the pulse gas flow to effectively improve the negative pressure suction capacity of the suction nozzle within a short time period, so as to meet the cleaning need for severe working conditions and ensure the cleanness rate of the road surface.

Description

technical field [0001] The invention relates to the field of road sweeping vehicles, in particular to a suction nozzle, a pulse air path control system with the same, and a road sweeping vehicle. Background technique [0002] At present, such a road sweeper has appeared, which has a suction nozzle body close to the ground. When the fan is running, a negative pressure is generated inside the suction nozzle body, so that the suction nozzle can suck the garbage on the nearby road surface and then send it to the ground. Into the dustbin connected with the suction nozzle through the pipeline, so as to achieve the purpose of cleaning the road surface. [0003] However, in the cleaning operation of this kind of road sweeper, when encountering severe operating conditions such as a large amount of road garbage or a thick layer of dust, the negative pressure adsorption capacity inside the nozzle body of the conventional suction nozzle is insufficient, so that the road garbage cannot b...
