Conveying rail with self-unchoking function

The invention discloses a conveying rail with a self-unchoking function. The conveying rail comprises a wide rail, a narrow rail, a monitoring mechanism and a cleaning mechanism, wherein the wide rail is communicated with the narrow rail, and an inlet of the narrow rail is communicated with a discharging port of a vibration pot. The monitoring mechanism comprises symmetrical sensors which are correspondingly arranged on the two sides of the wide rail. The cleaning mechanism comprises a high-pressure air source and an air nozzle, wherein the air nozzle is communicated with the high-pressure air source, is in controllable connection with the monitoring mechanism, and is fixedly arranged on the wide rail, and an opening of the air nozzle faces the narrow rail. The conveying rail is simple, convenient to use, and free of location and manual processing. By means of the design of the wide rail and the narrow rail, a similar filter mechanism which is added is far higher than a filter mechanism in efficiency, most of
