Abstract

A method for using parts and parts processing molds and accessories for washing and sweeping vehicles belongs to the technical field of mechanical engineering. A noise reduction suction port is composed of a suction port base, a suction port cover plate and a spoiler; The mold, the upper mold core, the lower mold core and the guide rod are connected; the suction cover processing mold is composed of an upper mold and a lower mold; the noise reduction suction port adopts a combined design, which is easy to disassemble and install. It is processed by casting molding, the processing method is scientific and reasonable, the manufacturing speed is fast, and large-scale processing can be realized in the same process. When the invention works, the suction cover has 4 spoilers with different angles to divide the inhaled airflow and pass it through. The sound waves coming in from different angles will cancel each other out, dissipate part of the sound waves through the crests or troughs of the spiral groove, and conduct through the spiral groove, so as to achieve the purpose of noise reduction, which can effectively reduce the noise of the air flow of the cleaning vehicle fan.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to an accessory for a sweeping vehicle and a method for using the accessory processing mold and the accessory, in particular to a combined noise-reducing suction port for a cleaning and sweeping vehicle, a processing mold and a method for using the processing mold . Background technique [0002] Noise refers to the sound emitted by the sounding body doing irregular vibrations, which propagates in a certain medium in the form of waves. From a physiological point of view, noise seriously affects people's physical and mental health. The creation and use of various mechanical equipment in modern society It has greatly promoted the progress of society, and at the same time, it will inevitably produce more and more noise pollution. For example, the sweeping car that cleans urban roads is like this. When the sweeping car is turned on, it will produce loud noise. The measured n...
