Device installed at front end of locomotive and used for cleaning steel rail sand grains

The invention relates to the field of steel rail sand removal, in particular to the field of removing sand grains accumulated on a steel rail of a rail transit system affected by wind and sand disasters, and particularly relates to a device installed at the front end of a locomotive and used for cleaning the sand grains on the steel rail. Sand grains are blown into the air through the fan at the front end of the locomotive, and the sand grains in the air are accumulated in a concentrated area through the ultrasonic part and then sucked through the sand suction device. And meanwhile, the fan on the side of the locomotive cleans the sand outside the area of the sand suction device, so that the sand on the steel rail is cleaned together. 本发明涉及到钢轨除沙领域，具体涉及到受到风沙灾害影响的轨道交通系统除去堆积在钢轨上的沙粒领域，尤其涉及一种安装于机车前端清理钢轨沙粒的装置。沙粒经由机车前端风扇吹起至空中，超声波部分使得空中的沙粒堆积在一个集中区域，再经由吸沙装置吸入。同时，机车侧方风扇清理吸沙装置区域外的沙粒，共同完成对钢轨上沙粒的清理工作。
