Foreign matter removing apparatus at track branch, and nozzle used in the same

A nozzle for a foreign matter removing apparatus at a track branch mounted at a track branch of rails so as to remove foreign matters having dropped between rails by injecting compressed air,

• the nozzle for a foreign matter removing apparatus at a track branch comprising:
• an injection housing of a conical trapezoid disposed at a front position of a crossing section where the rails intersect each other;
• one or multiple slits formed in a side surface of the injection housing so as to inject the compressed air toward a back position of the crossing section;
• and
• a guide unit disposed between a compressed air introduction port of the injection housing and the one or multiple slits to guide the compressed air from the compressed air introduction port of the injection housing through an inside of the injection housing to the one or multiple slits.

A nozzle used in a foreign matter removing apparatus at a track branch for removing foreign matters having dropped between a stock rail and a tongue rail at the track branch,

• the nozzle comprising:
• a piping unit for supplying compressed air;
• and
• at least one injection nozzle element for injecting the compressed air supplied from the piping unit;
• wherein
• the injection nozzle element comprises:
• a cylindrical housing disposed on an opposite side of the injection nozzle element to the tongue rail, and having a sloped portion approaching more closely to the stock rail toward a nozzle front end of the injection nozzle element;
• and
• slits extending through an inside of the cylindrical housing in a central axis direction thereof so as to inject the compressed air, at least some of the slits opening in the sloped portion, and none of the slits opening toward the stock rail,
• and
• a central axis of the injection nozzle element is oriented from a direction along the stock rail toward the tongue rail at a predetermined angle.
