[0002] A dust removal device refers to a device that separates dust from floating air, also known as a dust collector or dust removal equipment. The dust removal equipment utilizes a dust removal water pipe and a compressed air pipeline, adds a certain additive to water, introduces air pressure, and through a special device, completes a series of technological processes to generate water mist, which is sprayed onto the dust source through a distributor and a nozzle support assembly. In the prior art, a dust removal device for highway construction sites with the publication number CN214832291 U has achieved the effect of dust removal using the prepared water. By setting a drive motor, a rotating rod, and a drive gear on the drive bin, it is convenient to drive the rotating rod and the drive gear to rotate when starting the drive motor. By setting a rotating seat on the drive bin, and a rack and a water tank on the rotating seat, it is convenient for the drive gear to drive the rack to drive the rotating seat and the water tank to rotate when rotating, and then drive the lifting plate and the nozzle to rotate through a pulley along a sliding groove, thereby achieving the purpose of convenient nozzle steering spraying and improving resource utilization efficiency. However, the dust removal method and function of the above dust removal device are relatively single, so the dust removal efficiency is not good, and the existing dust removal device needs to be frequently maintained during dust removal, so the practicability and economy are not good. Based on this, the present invention provides an accompanying dust removal machine for highway engineering to solve the problems raised in the above background art. Summary of the Invention
